2021 TESLA MODEL Y Forward Collision Avoidance Problems

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12V battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “VCFRONT offline/unable to contact VCFRONT” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12V failure and says the overheating was due to an air pocket in the cooling system, but the VCFRONT messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of VCFRONT/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.

The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

On October 2, my Model Y battery was replaced with a defective cell. Tesla service center replaced the battery. The vehicle could not charge or operate, making it unable to be driven. Today, November 2, while driving my car, my Tesla ABS system and other battery components experienced total failure while driving. For a brief period of time, I was unable to brake completely and my vehicle felt like it was skidding. At the time this occurred, my 1 year old daughter and pregnant wife were in the vehicle. This could have been much worse.

I was driving along one of the main highways in Orlando, Florida called [XXX], on Wednesday [XXX], in my Model Y Tesla. I was between the exits of [XXX], and [XXX]. I was in the middle lane. There was a software update issued the previous Sunday. The warning came on the display that the lane changing was not valid. At that point the car took over and accelerated. The brakes would not work, until I slammed on it after 3 times, and the car began to decelerate. The air conditioner went off, along with the electrical turn signals. I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a concrete barrier, and a tree infront of the barrier. The car would not respond to park, neutral or the emergency brake. I tried re-booting the car 3 times and nothing. I had to call a tow truck to tow to the Tesla Service Center in Clermont, Florida. They could not get it in park either and had to drag the Tesla onto the flatbed. After 5 days of not responding to my text, I walked into another Tesla service center to plead my problem. Long story short, there is an unexplained anomaly that is in the CANBUS and cannot duplicate the error. More $ to have to tested for another week. They gave me a loaner to use, a Model S. After a few days driving it the loaner screen went blank and I was stranded. I had their loaner towed back to the service center. They will not 100% address the problem. They know it is in the CANBUS system, but now I definitely am scared to drive the car or get it back. How do I know if they will really tell me it is fixed? I fear if I get back in the car.

Tesla’s Full Self-Driving (FSD) system has repeatedly demonstrated unsafe behavior in my 2021 Model Y (VIN [XXX] , ~60,184 miles). The issues involve Adaptive Cruise Control, Lane Keeping Assistance, and Forward Collision Warning. FSD frequently follows vehicles too closely, leaving insufficient distance. When I disengage, I am left with no safe option: braking hard risks being rear-ended and triggers a hard-braking event, while lifting off the accelerator leaves me dangerously close, still flagged as unsafe following. FSD often waits until less than a mile before highway exits to attempt lane changes, causing last-second darting, missed exits, or unsafe maneuvers. It also performs excessive and unnecessary lane changes that add risk without improving efficiency. Merges are frequently unsafe, forcing me to brake hard to let others pass or accelerate aggressively to avoid being cut off. On several occasions, FSD has jerked or swerved into adjacent lanes without signaling, seemingly triggered by shadows or changes in the road surface. These phantom maneuvers are unpredictable and hazardous. On [XXX] at about [XXX], at a T-shaped intersection, FSD failed to yield to a vehicle traveling straight with the right of way while I was making a left turn. I had to slam on the brakes to disengage, narrowly avoiding a collision. This was the second such incident in the same intersection in one week. These repeated failures—unsafe following, late exit attempts, failed merges, phantom swerves, and failure to yield—create significant risks for me, my passengers, and surrounding drivers. The problem has been reported to Tesla multiple times via in-car voice reports and a written service request, and logs from my vehicle should confirm these events. No warning lamps or system alerts appeared before or during the failures. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Immediately after an over-the-air (OTA) update on Aug 8, 2025, my vehicle began showing camera connection errors and disabled multiple safety/ADAS features. Over the following days, I repeatedly received alerts that AEB was unavailable. The vehicle remained drivable, but AEB and related safety functions were inactive. Chronology: Aug 8, 2025: OTA software update to 2025.26.6 completed. Right after completion, the touchscreen displayed camera connection errors and disabled AEB / Autopilot / cruise control. Aug 11, 2025: While driving, I again received an “AEB unavailable” alert. Similar alerts appeared intermittently throughout the week. There was no water intrusion, impact, or external damage. Cameras were clean and unobstructed. I scheduled the earliest available Tesla Service appointment and reported the AEB failure as a safety issue. Service diagnosis: Tesla diagnosed a failure of the Autopilot computer (HW3) and ordered a replacement. Cost/coverage: I requested that the repair be covered by Tesla because the failure started immediately after the OTA update and I am a paid Full Self-Driving (FSD) purchaser. My request was denied; I was charged ~$1,600 (slightly discounted) for the computer replacement. Safety risk description: The failure disabled AEB and other forward-collision mitigation features without an external cause, beginning minutes after the OTA update. I consider this a safety defect because an advertised crash-mitigation system became unavailable during normal use, increasing crash risk. The timing suggests a possible software–hardware interaction (software change triggering or revealing a hardware fault) that could affect other vehicles.

I WAS DRIVING ON AN INTESTATE HWY I-70 EAST BOUND ON THE LEFT LANE AND I WAS ABOUT TO TAKE THE EXIST 62. I WAS ON CRUISE CONTROL AND IT WAS RAINING AND THE ROAD WAS WET. WHEN I TRIED TO CHANGE THE LANE THE CAR AUTO BRAKED AND CAR SKID AND ROTATED 360 DEGREES AND HIT THE RAILING. THE CAR GOT DAMAGED FRONT AND BACK. LUCKILY THERE WAS NO VEHICLE NEAR US SO MY FAMILY WAS SAFE. BUT I DONT KNOW WHY THE CAR AUTO BRAKED AND ONE SHOULD NOT HARD BRAKE WHEN THE ROAD IS WET. I CALLED 911 AND TESLA INSURANCE. I TOOK THE CAR TO THE BODY SHOP AND THEY ARE DEEMING IT TOTAL LOSS. PLEASE TAKE NECESSARY ACTIONS SO IT DOESNOT HAPPEN AGAIN

While reversing in this 2021 Tesla Model Y (software v12, 2025.14.1, Full Self-Driving Supervised), the vehicle’s ultrasonic sensors showed a wall directly behind on the display. However, the Tesla Vision camera system did not visually render the wall, and neither Automatic Emergency Braking (AEB) nor Obstacle-Aware Acceleration activated. The car reversed under driver input directly into the wall, causing a collision with property damage. The safety defect appears to be that the ultrasonic sensors, although still present and visually displayed, are no longer integrated into the collision avoidance systems after Tesla’s software updates activating Tesla Vision. As a result, the AEB and OAA systems seem to rely only on camera data, ignoring ultrasonic sensor input — leaving a dangerous blind spot in reverse. This problem affects safety because the driver receives no warning that AEB or OAA will not engage based on ultrasonic detection alone. Tesla’s updated owner manuals (2023.12) state that AEB is now designed to work in reverse, but in this case, the system failed. The issue has not yet been inspected by Tesla or a dealer but appears reproducible on vehicles with ultrasonic sensors running Tesla Vision software. This is likely a widespread defect affecting 2020–2022 Tesla Model 3, Y, S, and X vehicles equipped with ultrasonic sensors but updated via software. There were no warning lights or system alerts before the failure. I request NHTSA investigate whether Tesla’s software has disabled or failed to integrate ultrasonic sensor data into rear collision avoidance, creating an undisclosed safety risk for owners.

The Adaptive cruse control would stop working off an on. also it would give false land departure warnings causing driver to swerve thinking they were going to run into another care

The front collision warning is too sensitive and reacts unnecessarily to many events that are not a risk for collision. In addition, the sound of the warning is too loud causing the driver to become unnecessarily startled and may cause possible loss of control of the vehicle.

Several times on residential speed control the system does not recognize yellow flashing school speed reduction signs. Never slows or breaks. The speed of 25 mph does not register on the screed (other speed signs do). I told tesla service center when other services were being done. They said they were aware. I have seen no improvement over the last several months

Since March 2024, FSD has failed to function as designed. Tesla denied any problem with the vehicle until October 2024, when a manager told me it's a known issue with no available fix. The issue started with FSD not recognizing traffic signals. Meaning that regardless of whether a traffic light was green or red, the vehicle would treat it like an 4 way stop. It would come to a stop and then proceed through the intersection if it didn't detect immediate cars. This was dangerous and Tesla refused to acknowledge the problem for months. Since then the issue has evolved with FSD only engaging in certain situations (interstate driving). As of the most recent update, FSD won't engage at all.

This report addresses concerns regarding recent safety updates in the Tesla Model Y, specifically focusing on the "Rear Cross Traffic Alert" and the blind spot warning system. These updates are intended to enhance driver awareness and prevent collisions. However, there are significant shortcomings in their current implementation that may compromise driver safety. 1. Rear Cross Traffic Alert: Intended Functionality: The "Rear Cross Traffic Alert" is designed to warn drivers of approaching vehicles from the side when reversing, thereby preventing potential collisions. Current Implementation: The system currently highlights a portion of the infotainment screen in red when a potential hazard is detected. There is no accompanying audible alert to notify the driver of the danger. Safety Concerns: Drivers are likely to be looking over their shoulder or at their mirrors while reversing, rather than at the infotainment screen. The lack of an audible alert means that drivers may not notice the visual warning, especially if their attention is directed away from the screen. This could lead to an increased risk of collision, as the visual cue alone may not be sufficient to capture the driver's attention. 2. Blind Spot Warning System: Intended Functionality: The blind spot warning system is designed to alert drivers of vehicles in their blind spot when the turn signal is activated, helping to prevent lane-change collisions. Current Implementation: Similar to the Rear Cross Traffic Alert, the system highlights the screen in red when a vehicle is detected in the blind spot. No audible warning is provided to alert the driver. Safety Concerns: In adverse weather conditions, such as rain, drivers may rely more heavily on blind spot warnings due to reduced visibility. Drivers typically turn their heads to check for vehicles, which means they may not see the screen's visual alert. Without an audible warning, drivers may inadvertently change lanes into an occupied space, increas

This complaint addresses the recent changes made to the cruise control system in Tesla vehicles, as per NHTSA guidance in 2024. While the update aims to simplify the activation of enhanced cruise control, it introduces significant disadvantages and safety risks that need to be addressed. 1. Cruise Control Activation Update: NHTSA Guidance: In 2024, Tesla was required to modify the activation process for enhanced cruise control, allowing it to be engaged with a single pull when the option is selected. There are two options available: single pull and double pull. Advantages:  The update simplifies the process, enabling users to activate enhanced cruise control with a single pull, which is more convenient and user-friendly. Disadvantages:  When the enhanced cruise control is activated and the turn signal is engaged, the system automatically deactivates.  This deactivation causes the vehicle to stop maintaining its set speed, leading to a slowdown or complete stop. 2. Safety Risks: Driver Reaction:  The sudden deactivation of cruise control requires drivers to quickly move their feet back to the gas pedal to maintain speed.  This is particularly concerning when attempting to change lanes or merge into tight spaces, where maintaining speed is crucial for safety. Loss of Safety Features:  Upon deactivation of the enhanced cruise control, the vehicle no longer maintains a safe following distance, transferring full control back to the driver.  This abrupt transition means that the driver is left without the system's assistance to ensure safe driving and timely reactions, potentially increasing the risk of collisions. Increased Driver Workload:  Drivers must frequently reactivate cruise control after changing lanes, which demands additional effort and diverts attention from the road.  This constant need to manage the cruise control system can lead to driver distraction and increased cognitive load, potentially compromising road safety. 3. Recommendations: see attche

Summoned my car in parking lot. Vehicle showed on app that it planned to go straight then turn left but instead cut to a left and thus colliding with the car that was parked next to me. I have the footage if needed. Car should have stopped instead, or followed planned route. I was staring at the car the whole time and it looked that it was going straight, even after colliding, it looked like it was aimed to go forward. The car created a log of what happened if needed.

To Whom It May Concern: I am writing to report yet another dangerous incident of phantom braking in my Tesla vehicle. As a Tesla owner who has previously filed multiple complaints about this issue, I am deeply concerned and frustrated by the lack of resolution to this potentially life-threatening problem. Today, I experienced a terrifying phantom braking event that nearly resulted in a catastrophic accident. I was driving on a completely empty road with no traffic in sight - no vehicles behind me, none in front, and none approaching from any direction. Suddenly, without any apparent trigger, my Tesla aggressively applied the brakes, violently decelerating from approximately 25 mph to just 3 mph in a matter of seconds. This abrupt and unnecessary braking action caught me entirely off guard. The force of the deceleration threw me forward, and I narrowly avoided losing control of the vehicle. Had there been any traffic behind me, I have no doubt this incident would have resulted in a severe rear-end collision. The frequency and unpredictability of these phantom braking events make me feel unsafe every time I get behind the wheel. It’s only a matter of time before one of these incidents leads to a serious accident or fatality. Despite multiple reports to both Tesla and NHTSA, this critical safety issue remains unresolved. I implore NHTSA to take immediate and decisive action to address this problem. The safety of Tesla drivers, their passengers, and other road users is at stake. Please investigate this issue thoroughly and compel Tesla to implement a permanent fix for the phantom braking problem. Your swift action on this matter is crucial to prevent potential tragedies on our roads. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Tesla released a feature called Obstacle Aware Acceleration. The Owner's Manual states: "Obstacle-Aware Acceleration is designed to reduce the impact of a collision by reducing motor torque and in some cases applying the brakes, if Model Y detects an object in its driving path. The touchscreen displays a visual warning and sounds a chime when the brakes are automatically applied. For example, Model Y, while parked in front of a closed garage door with Drive engaged, detects that you have pressed hard on the accelerator pedal. Although Model Y still accelerates and hits the garage door, the reduced torque may result in less damage. Obstacle-Aware Acceleration is designed to operate only when all of these conditions are simultaneously met: Drive or Reverse is engaged. Model Y is stopped or traveling less than 10 mph (16 km/h). Model Y detects an object in its immediate driving path." However, my vehicle (and at least some other Model Y Performance models) do not behave in this manner. Rather than reducing motor torque when all of the above conditions have been met, it reduces torque every time the vehicle accelerates from a stop. This has been replicated by my local Tesla Service Center, and they confirmed the vehicle did not detect any objects in it's path. This is dangerous because the vehicle accelerates so slowly from a stop that I may not be able to avoid an accident if the vehicle doesn't accelerate as expected.

Twice, while in full self-driving mode on I-395, my Tesla has made the potentially fatal mistake of trying to turn the vehicle directly into the closed gates of the so-called "hot lanes" (which separate the north and sound bound lanes) and into on-coming highway traffic on those lanes. This is a serious safety issue that must be fixed IMMEDIATELY. This happened most recently on Sunday October 20, 2024, when I was driving south-bound on I-395 with my wife and son in the car. I was in the far left lane with "full self driving" activated. The hot lanes were to our left with all traffic on those lanes driving northbound. The gates to the hot lanes were closed to southbound traffic to prevent someone from driving directly into oncoming traffic. Shortly before we were about to pass those closed gates, the Tesla left indicator light came on and the car began to turn. The map showed the car was trying to turn us directly into the closed gates and oncoming traffic. Fortunately, I was paying close attention to this potential problem because the identical thing had happened previously, during the prior 30 day period when full self-driving was made available for free to all Tesla owners in April 2024. On that weekday evening, I was my driving my son northbound on I-395 after his basketball practice. The hot lanes were running southbound. Once again, as I approached the closed hot lane gates, the left indicator light came on as the car prepared to drive us through the closed gates and into the on-coming hot lane traffic. I am not a Tesla critic. I really like the car, but please address this issue ASAP before somebody gets killed.

This morning when operating on FSD trail version, at tye stop sign I had to make left. This is at intersection of Rueslane and Old bridge Turnpike of East Brunswick, NJ. My car started to make a left when there was an incoming car from the left, and they do.not have to stop. Thank fully the car on the left applied instant brakes and avoided tye accident. FsD failed to make right judgement if left turn was possible or not. Fsd version is v12.3.6

My Tesla still has the phantom braking problem. It is repeatable and consistent. I can tell when it will occur on a route that I drive regularly. Day or night does not seem to alter the occurrence. There is no indication on the touch screen when this occurs. Traffic volume does not matter. It always occurs at the same places so it should be relatively easy to fix if someone would just monitor my computer when it occurs. I regard this as a dangerous problem on the freeway because my car suddenly slows and if the person behind me is not paying attention, I am going to be rear ended. Such a serious fault for a vehicle that performs so well otherwise. Since Tesla does not have a service center in my town no one has offered to look at the problem but since it has been reported so often, I'm not sure they would. I would be happy to demonstrate the problem to a technical person who might be able to diagnose it.

The issue appears to be an acceleration malfunction and brake failure in my 2021 Tesla Model Y. The vehicle is available for inspection upon request. On [XXX] at [XXX], while waiting for the garage door to open, the car experienced an unknown unintended acceleration malfunction, surging forward uncontrollably. It didn't wait for the garage to open, crashed through the garage into the family room, causing significant structural damage to the framing and door. The City of Eastvale declared the house unsafe, sealing it off. I am now homeless and staying with friends temporarily. During the crash, the airbags did not deploy, and the ABS system failed, preventing an emergency stop. The car stopped 4-5 feet away from my wife, who was on the sofa, posing a critical life-threatening situation. Thankfully, [XXX] and I survived, but this incident caused severe mental trauma for my family. We have not reported the incident to Tesla. The dashcam footage appears deleted during the crash and the car seemed to have only recorded footage before the crash and after. This issue has not been reproduced or confirmed by any dealer or service center, but further investigation needs to be done. The vehicle has not been inspected by Tesla or any service center. However, the police and insurance representatives have been involved. We are coordinating further inspections to find the cause of the acceleration and brake failure. We aim to invoke the Tesla Event Data Recorder (EDR) tool to investigate what exactly went wrong with the car. There were no warning lamps, messages, or symptoms before the incident.

Tesla FSD consistently ignores temporary lane closures, and will cheerfully try to drive over the barrier poles. The locale is the San Diego Pure Water Project construction zones. They set up lane closures that change every week or so. They use a line of red poles along the middle of the road to block off a lane and direct both lanes of traffic into one lane. Sometimes there is also a large CLOSED sign in the middle of the closed lane. Tesla never sees the red poles and often does not see the CLOSED sign. I attach several photos each showing both the Tesla screen and reality in the same image. (Unless Tesla fixes this soon) I can send you lots more photos if you wish.

Tesla removed the ability to use only cruise control, with adaptive following distance, and have forced the only option to now use full self driving instead (with a recent soft-ware update). I do NOT feel safe using full self driving (even supervised) and believe Tesla is being unsafe forcing full self driving use. We used to be able to just use cruise control-with adaptive following distance-a driving option in all other recent cars!!! , but cannot do that now in Tesla? Why would a company take away what I consider to be a safer option?? This is not an improvement (but a forced help-Tesla-improve-it’s-unsafe-full self-driving-software!)

Since December when Tesla did their software update to supposedly make my car safer, I have been BURIED in warnings to keep my hands on the steering wheel and my eyes on the road. It seems like every 25-30 seconds, if I even glance over at the speedometer, I get a red "keep your hands on the steering wheel" / "Pay attention" warning. This is ridiculous. These distracting notifications could cause an accident.

March 31 I received an email from Tesla that I had been selected to participate in a free Full Self Driving (FSD) trial. I have no interest in FSD, and there was no way to opt out of this trial. At some point FSD was downloaded on to my Model Y as part of a regular software update. I was not given the opportunity to accept or refuse this particular feature. While both of these events feel wrong to me, it did not rise to the level of reporting to NHTSA until I realized Tesla had also ENABLED FSD on my car. In other words they switched my configuration from Auto Pilot to Full Self Drive, presumably as part of the software update that downloaded the software on to my vehicle. One could argue that because two features on my screen were different I was able to figure out my configuration had changed, and manually change it back. One could also argue that not everyone would sort this out, and the next time they pulled the stalk down to engage cruise control they would unknowingly engage FSD. And that is not OK. I find the timing of all of this ironic given Tesla just settled out of court on a fatality related to their vastly overhyped FSD.

The vehicle's primary Autopilot processor randomly and completely failed while in active use on February 10th, causing the vehicle to immediately change course towards a highway barrier at high speed. Since that moment, every time the Autopilot DAS computer is reset, the primary processor refuses to transition from the INIT state to the NOMINAL state and instead transitions to CRITICAL state. The vehicle had software update 2023.44.30.8 for recall campaign #23V-838, recall number SB-23-00-008 applied 1 month ago, which was supposed to decrease the probable misuse of the DAS system. However, many individuals reported that the recall immediately and irreversibly damaged their DAS computer, so Tesla offered them a free replacement without hassle. However, I have been struggling to work with Tesla's Carlsbad, California service center for over a week to get the DAS computer replaced at no cost, since the computer was damaged after an update caused the computer to become irreversibly damaged after their software update was installed -- a software update which was supposed to have made the Autopilot system safer, but which has instead unfortunately irreversibly damaged the Autopilot computer, and caused my vehicle to randomly and immediately weave towards a highway barrier at high speed. I am wrongfully being asked to pay in excess of $2500 for a replacement computer as a result of the update damaging the DAS computer. They claim the catch-all diagnosis of a "short circuit" internal to the DAS computer caused the damage which would be out of warranty, except the computer has never been opened by myself. They confirmed to me that they chose that diagnosis after a process of elimination without actually probing the electrical system within the computer. The Carlsbad service center refuses to give me an accurate estimate for any further engineering analysis, claiming it could take multiple hrs/days at $245/hr. This is extremely unreasonable and presents unlimited risk.

I was driving to work this morning, February 7th, 2024 driving at freeway speeds. My Tesla touchscreen dropped out and went completely dark. The reset process is to press and hold for about 30 seconds and another 30 seconds for the full restart. I attempted this twice and proceeded to pull off the highway. During this period, I could not see how fast I was driving, whether my brake lights, turn signals, or headlights worked at this time to safely transit through traffic to get off the road. I put my hazard lights on, but again did not know if these worked or not. The screen finally came back online and seemed fine until I could get to work, this was an extremely scary experience and a perfect example as to why all cars should have a cluster driver screen mandatory, I will be getting rid of this car as soon as possible.

The most recent recall and modifications to Autopilot have dramatically reduced subjective safety. I am more distracted by warnings and interventions by the system. The system is less able to adapt to changing conditions. It seemed to be far more effective from a safety standpoint prior to the recall. People were and are the problem with autopilot, not autopilot. As with people, it made/makes mistakes. But an attentive driver easily corrects. Full Self Drive is different, but if any driver has ever been under the illusion that autopilot does not require full attention, it is the driver's fault.

Since installing the update for 23V-838; TC2023-657 compliance, you guys have absolutely ruined autopilot. Your regulatory overreach has resulted in my task workload increasing while using any ADAS systems Tesla supplies, and multiple times I have reached task saturation from the number of nags, alerts, and prompts that have appeared since applying the 23V-838; TC2023-657 update. In some cases I have engaged autopilot, been nagged, wiggled the wheel which disengaged, re-engaged, been nagged, wiggled the wheel which disengaged, re-engaged, 3 times in a row. I have benchmarked almost every other ADAS system on the market and you [XXX] have somehow regulated tesla auto pilot into a place where it has literally the most frequent nags, alerts, prompts, and annoyances of anything on the market. Ask yourselves whether you honestly think nags that audibly prompt and distract the driver for merely glancing at the autopilot set speed, briefly adjusting the map, or even daring to adjust vent position are really a wise tradeoff, or just something you cooked up because you have an axe to grind. Here's another one - as petty bureaucrats, would you rather have Autopilot or FSD on the road, or a hypothetically drunk driver?

Tesla Autopilot lost control in rainy weather, swerved off the road on freeway at 80mph, swung back in the leftmost lane and then to shoulder, risking lives of driver and all passengers including 2 children. Impact resulted in broken wheel rims and bursted tires. This could have been fatal accident if there are other cars on the road at the time of incident. There were absolutely no warning on the screen and near zero time to react with vehicle wheels turning sharp left at 80mph. Footage though immediately visible on DashCam has disappeared from USB drive. Requested vehicle logs from Tesla but that too has gap in coverage exactly during time of accident. Tesla Service Center has not responded to request to get system log at the time of accident. Missing logs and camera footage exactly at the time of incident is suspiciously missing. Footage and logs are available for next day as well as several weeks and months in the past.

While driving on highways using adaptive cruise control, the vehicle will slow down quickly from highway speeds of 60 to 75 mph, down to 40 or 45 mph without the presence of an obstruction in front, such as a vehicle, or even a shadow, that could fool the vehicle’s camera. This puts us at risk of being rear-ended on the highway. The problem happens randomly. I have reported the issue to Tesla twice. It happened once while on the phone with a Tesla representative that had called me back regarding my reported complaint. The Tesla rep said they were aware of the issue and were working on correcting the issue via a software issue. Tesla has cancelled my requests for service appointments regarding this issue. In September of 2023 we attempted to use the cruise control to see if it had been repaired but it happened again. There were no prior warnings. The issue first appeared in September of 2021. It has happened many times since then. I first reported around Sep of 2022.

After the latest recall (campaign #23V-838), the automated warnings while using autosteer becomes so frequently that it becomes distractingly dangerous. Even when i briefly avert my eyes while driving on an empty highway results in the warnings

Subject: Safety Concerns Regarding Recent Model y Autopilot Update To Whom It May Concern at the National Highway Traffic Safety Administration (NHTSA), I am writing to urgently express my concerns about the latest software update for the Tesla Model Y’s autopilot system, which, in my view, significantly compromises safety. As a Model 3 owner for over one year, I have generally found the vehicle and its features to be reliable and safe. However, the recent update has introduced an overly stringent hands-on-wheel detection mechanism that is not only inconvenient but also potentially hazardous. The new update requires frequent and often forceful interaction with the steering wheel to assure the system of driver presence. This change is drastically different from my previous experience, where I received only one hands-on-wheel violation in two years. The current sensitivity of the system disrupts the smooth operation of the autopilot, leading to frequent and abrupt disengagements. I have found myself struggling to maintain the system’s activation, inadvertently causing the vehicle to exit autopilot mode multiple times. This issue goes beyond mere inconvenience; it actively detracts from driving safety. The need for constant and sometimes aggressive adjustments to satisfy the system’s requirements is distracting and can lead to erratic vehicle behavior. The irony is stark: a system designed to enhance driving safety and ease is now a source of potential danger and stress. The unpredictability and over-sensitivity of the updated system could lead to dangerous situations, especially on highways or in heavy traffic, where sudden disengagement of the autopilot can be particularly risky. As a driver, I now find myself more focused on keeping the autopilot engaged than on the actual driving conditions and surroundings, which is surely contrary to the feature’s intended purpose. Thank you for your prompt attention to this serious safety concern. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

After Tesla software update 2023.44.30.2, the rear back up camera no longer works. It’s just a black screen. Failure first occurred on 12/20/2023. Also, Tesla “Auto pilot” no longer works (cruise control and lane assist). Support team could not fix both issues. Have a service appointment scheduled on 12/27/2023. Thank you and happy holidays.

The Regenerative brakes malfunctioned looks like and the car kept on spinning and we hit the side of the freeway and ended up in a ditch and the tow truck had to pull us out of the rubble. it was very scary and lucky we did not get hurt. I was reading some online reviews and looks like many people are having similar issues with Tesla Model Y and other Tesla Models. thanks

Phantom braking. We were going at around 45 miles per hour on route 30 and the car suddenly engaged brakes without anybody in front of me. Apparently it's a known issue called phantom braking and I wanted to report it

What component or system failed or malfunctioned, and is it available for inspection upon request? Emergency Breaking in Autodrive mode. How was your safety or the safety of others put at risk? My car auto breaked hard for no apparent reason when I was driving at 75 MPH on an open highway. Has the problem been reproduced or confirmed by a dealer or independent service center? There are plenty of articles online about Phantom Breaking. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, this happened yesterday morning on 11/18/2023. I plan to report this to Tesla today as well. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Not a single warning and this was the first time that this has happened to my vehicle. I was driving using auto drive at 75 MPH on highway at 8:45AM on 11/18/2023. All of a sudden, and for no reason, my Tesla Model Y slowed down within 3 seconds to around 45 MPH. This was completely unexpected as no other car, debris, person was near me. When I got. home that day, I read about phantom breaking with the Tesla. What happened to my car is yet another example of phantom breaking. This could have caused a major accident if there were more cars on highway at the time. Luckily no one was injured, but my daughter and I were in shock and shooken up.

My car has had a problem with TACC since the day I bought it. Brakes aggressively in what should be a normal driving situation. For instance, when I pass a semi truck on the interstate with my own lane in front of me, the car will slam on the brakes when it is beside the truck. Highly likely to cause a rear end collision.

Car will, without warning brake aggressively while in cruise control, without pressure applied to brake. No other factors on road, except cars behind. This occurs frequently when car is driven in autopilot. Car will, without warning accelerate to a high speed without pressure applied to the accelerator. This acceleration is stopped with pressure being immediately applied to brake.

While in cruise control, car will randomly suddenly brake without warning or visible obstacle. This has been an ongoing problem ever since buying the vehicle in 2021. Very dangerous as it has happened on the highway. Is startling and causes seat belt locking. I have reported the issue to Tesla and it's apparently a "limitation of software". We usually do not use cruise control in the Tesla because of the dangerous of this, but I decided to try again recently in hopes they had fixed it but to no avail.

driving from Albuquerque NM to Farmington NM, in approximately 1 1/2 hours of driving on hwy 550, 4 lane divided highway, encountered no less than 12 hard shadow breaking events. in all instances there were no vehicles, animals or debris in front of the vehicle. It was a cloudless day, starting around 9am, clear no fog, temperature in the 40's. high risk of being hit if a car was following close behind, incident has been reported to tesla, no inspection. there was no waring prior to all hard shadow breaking events.

When travelling with adaptive speed control enabled the car will suddenly and violently decelerate 30 to 50 MPH below the set speed. This happens frequently and does not appear to correlate with anything specific. Sometimes it happens when passing a large white truck. Sometimes there is no other traffic anywhere near me. At the very least I would like Tesla to give me the option of disabling the "safety" features so the car operates like every other car with adaptive cruse control. This is not just me. Search the internet for Tesla phantom braking and you will find many instances going back years. It seems to be getting worse with each software update.

Driving with cruise control on the car would suddenly brake for no reason. Sometimes it was just a quick brake for a second or two but multiple times the car braked hard enough to have things in the car fly off the seats. These incidents happened on 9/5/2023. Needless to say we didn't use the cruise control after that, we are just glad no cars were behind us at the time. If this helps, we did use cruise control on a trip on 6/24/2023 with no issues.

Subject: Formal Complaint Regarding Vehicle Fire - model y performance 2021, XXXXXXXXXXX Dear Tesla Customer Relations & CarMax, I am writing to express my deep concern and file a formal complaint regarding a serious incident involving my Tesla [model y performance ,, 2021, XXXXXXXXXXXXX], which caught fire on August 1st 2023 while in operation. This incident has raised significant safety concerns for me and my family and requires immediate attention and resolution. The vehicle fire occurred under normal driving conditions, and thankfully, no one was injured in the incident. However, the fire resulted in substantial damage to the vehicle and posed a significant risk to nearby properties and individuals. The incident has left me shaken and worried about the safety of Tesla vehicles. I have attached the following documents and information for your reference: I have been a loyal Tesla customer and have appreciated the innovative features and benefits that your vehicles offer. However, this incident has eroded my confidence in the safety and reliability of your products. I kindly request a thorough investigation into the cause of the fire and an explanation of the circumstances that led to this incident.

Furthermore, I urge you to take immediate action to prevent similar incidents from occurring in other vehicles. Safety should be the utmost priority for any automobile manufacturer, and I hope Tesla will take swift measures to address any potential risks. I understand that accidents can happen, but it is essential that Tesla demonstrates transparency, accountability, and a commitment to ensuring the safety of its customers. I expect to be kept informed about the progress of the investigation and any steps that will be taken to prevent future incidents. I appreciate your prompt attention to this matter and expect INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

When autopilot is engaged (I don't know if just cruise does this) on a highway entrance set to a reasonable speed like 35 or 45, as I approach the acceleration ramp the setting jumps to 90 and then quickly back to 85. I've found no reason to beleive that the car won't accelerate up to 85. There is no way for the driver to make such a jump. Driver is only able to jump in 1 or 5 mph increments. I have no trouble disengaging autopilot, but still... This has been going on for weeks, and despite a software update or two. I can provide video of this happening but I don't think I can upload it here.

During raining multiple teslas including my tesla last week experienced hydroplaning lead to close ti fatal accidents I believe the car inappropriately used emergency breaking that lead to accident, i am not if that was due to the car seeing water/reflection ln the ground I was driving the speed limit and all cars were driving at the same speed 70-75 mile per hour) I suddenly started spinning with no warnings It is impossible that multiple teslas experienced the same thing more than other cars I am trying to get the data from tesla to confirm this, but it is not easy to make them get us what exactly happened I am seeking third party analysis hopefully once i get the data, but it would be best done from NHTSA The damage to my car was due to hitting the road and my car went to the middle due to hight difference No other cars or objects were hit If i hit anything, it could have been fatal

This has occurred on three different occasions. I was driving on highway five on the way to Sacramento, and as I was passing a truck, I was in the fast lane, and the brakes came on, and the car slowed drastically. I was very lucky that I was able to hit the gas pedal to try to maintain speed so that I would not be rear-ended. I had the cruise control on. It is adaptive cruise control, there were no warning lights , and there was no indication to me that something was about to happen. This occurred on two other occasions always when the cruise control was on. I have not used the cruise control very much at all. I am afraid that the phantom breaking it will occur.

Driving Down freeway at 70 mph when my car stopped immediately ! No one or nothing in front of me . 6 cars behind me and everyone swerved to avoid me or they would have hit me. I was terrified. I called Tesla and they said it was “phantom breaking”. It happens to model 3/Y from 2021 and 2022. It happened 2x in an 8 hr period. July 22, 2023

Dear Tesla Customer Support, I hope this email finds you well. I am writing to express my extreme concern and disappointment regarding a serious malfunction I experienced with my Tesla vehicle, Model Y, on 08/01/2023. The incident has left me deeply troubled and has raised significant questions about the safety and reliability of your vehicles. On the aforementioned date, while I was driving my Model Y, I noticed an unusual burning smell coming from the vehicle. Shortly after, the cruise control system began to malfunction erratically, leading to a loss of control over the vehicle's speed. In a matter of seconds, the display and all lights on the dashboard went dark, leaving me unable to monitor crucial information such as speed, battery level, and vehicle warnings. Worse yet, the electronic power steering suddenly failed, causing an immediate stiffening of the steering wheel and making it incredibly difficult to control the vehicle. As a result, my car veered into a curb, causing damage to the wheels and suspension and fire. I cannot stress enough how distressing this situation was. Not only did it put my safety and the safety of others at risk, but it also raises questions about the reliability and effectiveness of the various systems within the vehicle. I have always trusted Tesla's commitment to innovation and cutting-edge technology, but this incident has shattered my confidence in the vehicle's reliability. I am writing to urge you to take immediate action to investigate this malfunction thoroughly and provide a comprehensive explanation for what transpired. I request a detailed analysis of the root cause of the issue and assurance that appropriate measures will be taken to prevent such incidents from occurring in the future. I have been a loyal Tesla customer for 2 years and until this incident, I have been delighted with the exceptional performance and features of your vehicles. However, this incident has left me deeply concerned, and I sincerely hope

Phantom Braking. When there are refractions on the road seen in my lane in bright sunshine. Also in a 2-lane highway with oncoming vehicles that have lots of chrome also in bright sunshine. Never happens at night or when cruise control not enabled.

I was on the highway with cruise set to 80. With no vehicles anywhere near in front of me, the car brakes hard and the cruise was set to 50. I was able to gain control by hitting the accelerator but slowed down quickly from the phantom breaking.

Approximately 11:26 am on Thursday July 27, and approximately 110 miles east of Gallup, New Mexico, I experienced when driving a 2021 Tesla Model Y, a series of extreme phantom braking events. One phantom braking event resulted in an extreme braking and the car gave a loud alarm signal. This happened while passing two rather closely spaced semi-trailer trucks that were in the right lane of the interstate highway 40 roadway going westbound. Both trucks were traveling without making any unusual movements. They were steadily traveling between 70 and 80 mph. There was a large SUV following our vehicle. This event resulted in an extremely hazardous condition. A high-speed rear-end collision was imminent. I, as the driver of the Model Y, immediately accelerated and steered over to the left-lane shoulder. No collision occurred and I was able to pass the two trucks and return to the right lane. Clearly, this behavior of the Model Y is extremely hazardous and must be corrected. It is my recollection that I had disengaged the auto steer mode prior to passing the two trucks and then reengaged the auto steer after passing the two trucks and moving to the right lane. I have experienced this behavior before as I have been driving the vehicle for the past two years of my three-year lease. Strangely it always occurs, it seems when driving on rural interstate, such as this case. Fortunately, these experiences helped me to instantly respond by accelerating and moving onto the left lane shoulder to avoid a disastrous accident. It is appalling that this has been happening. The Tesla gives absolutely no indication of the cause of the urgent breaking either before or after the event. Also there has been no notifications from Tesla on this dangerous phantom breaking. I am sending this report to Tesla and the NHTSA.

My family and I were driving from San Diego to Arizona on Interstate 8. I was utilizing autopilot (adaptive cruise control with lane keeping assistance) and 4 different times the car slammed on the brakes from approximately 75 mph to 60 mph. We were driving on a bright, sunny, extremely hot day (116 degrees). Luckily there were no cars behind us or we could have been rear-ended. It's also noteworthy, there were no cars/vehicles in front of us or objects in the road when the phantom braking occurred. I now no longer feel safe using autopilot on our Model Y. No warning messages appeared and no additional information was provided by the car. We have used autopilot on several other road trips and never experienced this issue.

I was driving the speed limit with the adaptive cruise control engaged on I-95 in Maine with no one in front of to the sides of me. All of a sudden without warning my car brakes on the middle of the highway. I regained control right after and did not use the adaptive cruise control for the rest of the drive.

Phantom braking in autopilot. Traveling at 75mph with traffic behind, fortunately the car behind was not following closely. No warning message beforehand, just happened very suddenly with no obstructions in sight. Weather was clear and sunny, no traffic in front. Two minutes later, the car completely ignored a deer standing on the hard shoulder!

We have recently experienced a significant and concerning increase in incidents of phantom braking and have thus far been unable to receive an adequate response from Tesla. We have had at least six instances of this occurring today, 16-Jun-2023 in the first 6-7 hours of our cross-country drive, and I’ve shared these time stamps with Tesla service. This is because we experienced this same thing 2-3 times on another long drive in November of 2022, and Tesla service told us at the time they couldn’t do anything about it unless we had time stamps because otherwise, it’s too many pages of code to sort through and beyond that, you have to notify them within 12 days of the incident or they can’t look into it at all (which is what happened with me- although I had to chase them to even get a response). They also said it was a “known issue” but were unsure about a planned remedy. I took screenshots of that conversation with Tesla service and have attached to this submission in the event that’s helpful. We are still pending a response from Tesla service for the multiple incidents today. Interestingly, we had taken this car on multiple lengthy drives in all types of conditions prior to Nov 2022, but never experienced this issue previously. It certainly seems to be increasing in frequency and intensity (I know my n=1 for my sample size here makes this somewhat anecdotal, but it’s terrifying regardless) and it seems like only a matter of time until tragedy strikes.

Countless times, at high legal speed, with adaptive cruise control enabled, on a straight blemish-free level highway with perfect visibility, sudden automatic deceleration was experienced-- several times every hour over 11 hours of driving. I have video recordings.

Repeated "phantom braking" caused by shadows from clouds, pavement coloration changes, billboards some distance from the highway, large advisory signs, and even pieces of blown-out truck tires on the shoulder produce sudden deceleration of over 30 mph in just seconds from the automatic emergency braking system on my 2021 Model Y Performance. This mostly occurs on interstate highways or secondary highways when the vehicle is in cruise control or auto steer with cruise control mode. A recent trip of several thousand miles produced over 20 cases of phantom braking. The windshield area in front of my forward facing cameras is always kept clean. HAZARD: It has created the risk of rear-end collisions, or stimulated road rage from following drivers.

While driving eastbound on the CA60 freeway and merging onto the Interstate 10 freeway, on a clear sunny day and on a dry road, without another vehicle beside the car, with the 'autopilot' (not full version) engaged, the car suddenly initiated an uncommanded acceleration which required the driver to aggressively depress the brake pedal to stop the acceleration and to disengage the automated driving feature. This sudden acceleration brought the vehicle dangerously close to another vehicle traveling in front before it could be stopped. Witnesses were in the car when this incident occurred.

While driving northbound on the CA111 freeway along an elevated ramp leading to the Interstate 10 freeway, in the evening after sunset, and on a dry road, without another vehicle beside the car, with the 'autopilot' (not full version) engaged, the car suddenly initiated an uncommanded acceleration which required the driver to aggressively depress the brake pedal to stop the acceleration and to disengage the automated driving feature. This sudden acceleration placed the driver and occupants at risk to the car traveling around an elevated tight curve with a ramp speed limit that the car exceeded. Witnesses were in the car when this incident occurred.

While driving at speed (75-80 mph) on Interstate 90 and 80 (different days) auto aggressively applied brakes. No other autos, trucks or obstructions were anywhere close to the car. There was no forewarning the problem was going occur. All occurred in daylight from morning until mid afternoon. I recognize this as phantom braking. Tesla refuses to look at the car because I did not have the exact time the problems occurred, messages from 6/2/23. I am of the opinion if this was Elon's car they would look at it.

For last several months my 2021 Tesla Y is experiencing phantom braking while using cruise control. Happens about once every 50 miles on the highway and occurs on straight roads with no traffic in front or behind and no road hazards. Braking is sudden and hard and represents a significant hazard . Thanks

On a trip from Spokane to Seattle on 5/27/2023, while traveling at 72mph on I-90, we experienced “phantom braking”. This resulted in the vehicle rapidly decelerating based on its detection of something in front of the car to avoid a collision. This occurred 3 times on the trip, and in no case was there anything for the vehicle to avoid. Weather was clear and road conditions were dry. Our biggest concern is that there could have been someone following directly behind, and would have certainly caused an accident if this were the case. The Tesla was in “autopilot”, which is the only mode we have experienced this. We experienced this last year on the same stretch of I-90, just east of Moses Lake to just west of George Washington.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 55-65 MPH, the vehicle experienced "Phantom Braking". The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 22,000.

Mileage: 22,000

Driving I-80 on May 9 between 2 - 4 pm going approx 70mph using autopilot. Sudden, unexpected, rapid deceleration causing back seat contents (suitcases & my dog) to fly forward. Nothing in front of me, no visual obstruction, weather clear and sunny. Luckily no one behind me. It felt like I had slammed on the brakes. I did get off highway shortly after to get dog out of where he lodged in back seat.Tesla rep via text messaging said I caused this by tapping accelerator & no need for inspection, but I do not recall doing that. I did receive a message/warning around the approx time I think this occurred stating “Driving visualization temporarily degraded” (I have screenshot.) They did send me the spreadsheet data of that day but I can’t decipher it.

The problem I am writing about is not specific to my Tesla vehicle, but inherent to all Tesla's. I have read in the news about the issue concerning the full AutoPilot with drivers not paying attention figuring the vehicle will drive itself. Although, there is another inherent issue with vehicles without subscribing to AutoPilot while using the cruise control feature resulting in a problem referred to within the Tesla community as "phantom braking." While the cruise control is active and the driver is attentive with hands on the steering wheel, the vehicle intermittently jams on the brakes even though there are no obstacles in the road ahead. The driver and passengers are panicked requiring the driver to immediately respond by pressing the accelerator to avoid being rear-ended. My wife and I have experienced the issue on multiple occasions since owning our Tesla Y since September 2021. We have experienced the issue on clear days with perfect weather and a clean windshield. The road is clear with no vehicles in front of us on a divided highway traveling at highway speeds. We've also experienced the issue on a two-lane non-divided road with oncoming traffic in the other lane. Eventually, the problem becomes such an issue that we have to turn-off the cruise control to drive normally which defeats the reason why cruise control is desired. I had presented the issue with Tesla support, but I was basically blown off. Although, this issue is frequently commented by other Tesla owners on social media. Basically, the Tesla cruise control does not function like any of my other car's cruise control. The problem is thus software related to how the images from the camera are interpreted. I'm worried about my safety with the possibility of being rear-ended.

Over the past 2 weeks there have been multiple (5+ times in one day) instances of phantom breaking both using adaptive cruise control and autopilot. This often happens when approaching a bridge but also in areas where bridges are not present. Sometimes the sun may be towards the front of the car, sometimes not. Luckily no collisions, but the sudden breaking is a safety hazard and prevents the use of the car’s advanced features that are meant to reduce driver fatigue.

Phantom Braking while driving interstate 15 on May 8, 2023 at 11:15 AM. No other cars were within a half mile in front or behind. Car went from 70mph with hard braking until I took control to regain speed. Had there been other vehicles behind me, it could have resulted in a rear end collision. Reported to Tesla today, May 15th, but told there is no fix. I have not used the Autopilot feature much at all, since most driving is short city trips. I do not intend to use this feature for safety concerns.

I own a 2021 Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, Ca. Ever since, I have had thousands of instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. On January 26, 2022, I had 47 documented episodes, in just two hours. The experiences of severe phantom braking have been terrifying. The car often slams on its brakes for no apparent reason, many times on a four lane highway, or on a freeway with no cars or obstacles. I worry about getting rear-ended, which could end in severe injury or death. It has been in for repair five times, and the technicians are animate that a software update is coming very soon to resolve this problem (they've been promising that since a few weeks after taking possession of the Tesla). I expected the problem to be resolved by now. It hasn't. The AEB continues today. Can you please force Tesla to fix this problem immediately? It is very dangerous. Please provide a response identifying actions you are taking to resolve this very important safety matter.

For the FSD beta, it does not currently parse and respect road signage such as “No Turn on Red” and “Detour”. This constitutes a material safety risk and also a moving violation.

I experienced multiple instances of ghost braking while driving at highway speeds, one that resuled in a near collision with the vehicle behind me.

I was driving down the highway. The weather was clear. Sunny. The road was dry. Middle of the afternoon. I was using the Adaptive Cruise Control. I was driving the speed limit, 70 MPH after driving for a couple of hours, the car had about three different times when it felt like the brake was tapped, the car slowed a bit and then regained speed. I stopped at my destination for about 4 hours and then returned home. Same roads conditions, sunny, dry road, etc. Same road, 70 MPH, the car suddenly hit the brakes HARD. Slammed might be too strong of a word because it's not like the car left skid marks on the road, but the brakes hit very, very hard. The car slowed to 25 or 30 MPH. Fortunately there were no cars behind me or me and my wife could had been killed right then.

Last weekend, during a 600-mile road trip, I experienced at least 20 instances of phantom braking when using the traffic-aware cruise control. A rapid deceleration of the car for no apparent reason is dangerous and needs to be fixed. I have complained to Tesla on a couple of occasions and there now seems to be more instances of the braking issue occurring since my last highway trip.

Phantom braking of Tesla: While using the AutoPilot feature to assist driving, on April 13, 2023 between 10 am and Noon while traveling on US Highway 2 on a clear sunny day on a 4 lane highway with excellent visibility and no traffic, the Tesla suddenly and unexpectedly slammed on the brakes for no apparent reason. I placed a service request to Tesla the next day and the texting Tesla service tech said he need a timestamp within 5 minutes of the incident. Because I could not define the time within 5 minutes of when it happened, there was no further information available. We finished the texting episode by cancelling the service appointment and I will not use the AutoPilot feature on the Tesla until Tesla says it is safe. I feel the phantom braking issue, if traffic had been present, could have caused a chain reaction collision by other cars trying to avoid the rapidly braking Tesla.

On the evening of April 18, 2023, I was driving on the southbound 101 in Northern California using autopilot, and despite the surrounding area being clear of other vehicles, pedestrians or debris, without warning, the autopilot system forced the vehicle to suddenly and harshly brake. It was completely unwarranted and unexpected and really gave me and my passenger a scare, and this ain’t the first time it occurred. We purchased our vehicle in November 2022 and in December we were using autopilot on the 405 south in Los Angeles, traffic was moving at a steady 70MPH when the vehicle abruptly braked, thinking it was a one-off we didn’t report it but after reviewing several complaints of similar issues by other Tesla owners, this is a real problem. I saved the event on my Tesla dashcam.

Severe phantom braking incident - 12:18 CST, March 12th 2023, followed by less severe braking problem at 1:16, 1:23, 2:18 on the same day and road. No forward traffic, no hazards, just bright sun. The car with a less experienced driver applied hard braking nearly causing a rear end collision with a truck approaching from the the back. The truck moved into the shoulder and passed to avoid hitting the car.

Vehicles continues to make random unwanted and dangerous sudden braking at highways speeds while the cruise control is engaged.

The contact owns a 2021 Tesla Model Y. The contact stated while driving approximately 75 MPH with the "auto pilot" and the "cruise control" functions engaged, the vehicle made an emergency stop. The contact stated that the force of the emergency braking had thrown him forward into the seat belt. The contact stated no warning light was illuminated. The contact was able to disengage the auto pilot and cruise control and continued his trip. The contact stated that the emergency or "phantom braking" had become a recurring failure. The contact scheduled a remote service for the vehicle and an over-the-air software update had been performed. The vehicle had been repaired. The contact stated that the failure continued after the software update. The manufacturer had been informed of the failure. The failure mileage was approximately 18,000.

While utilizing the ADAS features including the adaptive cruise control, the vehicle unexpectedly applies its brakes while driving at highway speeds.

Vehicle began showing the below warning messages, followed by loss of power steering and abnormal braking behavior (brakes did not work properly). This is a recurrence of an issue that previously resulted in the vehicle being towed to Tesla, but whom were unable to diagnose the problem. -Automatic Emergency braking disabled -Lane Departure Avoidance features unavailable -Traction control disabled -Automatic vehicle hold disabled -Stability control disabled -Steering assist reduced -Front motor disabled -Power reduced

Sudden deceleration and braking while at interstate speeds and crossing over a bridge. I was using cruise control only, overcast day, dry pavement with moderate traffic. Cruise control strongly applied the brakes from interstate speeds while crossing over an overpass bridge. There was no danger or traffic ahead of me that should have triggered the emergency braking. This needs to be investigated, it will get someone killed.

We recently traveled about 300 miles on a roadtrip in this Tesla and while using the adaptive cruise control, the car would randomly slam on the brakes for no apparent reason. There was nothing in the road or any hazards at all. Also, it was not just a one time thing. It happened multiple times before I decided to not use the cruise control because it to dangerous.

This is my second NHTSA report for this car, there was no reply to my first report. Since the manufacturer, without warning or owner consent, disabled radar systems for automated cruise control, the car is now exhibiting a new dangerous behavior when the camera detects the presence of emergency vehicle flashing lights and suddenly, and dangerously applies an emergency brake to slow the car, without taking into consideration the location of the emergency flashing lights relative to my car, or the presence of other cars around me that might be affected by the sudden, un-announced braking of my car. In many cases, the police/emergency lights are on the opposite side and direction of the freeway, 8+ lanes away from my car, and I am under no legal obligation to brake, nor would it be safe to do so. There is no warning by the car, only the sudden braking action and I have almost been hit from behind by other cars who were not expecting my car to brake while at freeway speed. This event has occurred at least 10 times in the past year regardless of time of day, weather or traffic conditions. I would like the previous complaint I filed about sudden, unexpected braking, as well as this new complaint reviewed by the NHTSA, as this is evidence of a critical, significant safety hazard by the car which the manufacturer has deliberately created.

This car is unsafe. 70K+ purchase price with the inability to use basic cruise control, must-less the 10K FSD purchase that is USELESS. The phantom braking is constant while trying to use the basic cruise control, auto-pilot/FSD. Driving this car makes me a nervous wreck and I am beginning to HATE it and regret my purchase. I am seriously concerned for the safety of myself and other Tesla owners based on the current radar-less autonomous features. NHTSA should get involved and force Tesla to address the phantom braking issues before more people are involved in an accident that could be avoided.

ON MARCH 18, 2023 WE WERE DRIVING ON HIGHWAY 80 FROM Winnemucca NV TO FERNLEY NV. At 3pm and about 3:10pm the car suddenly decelerated from ~82mph to ~50mph. The road ahead was clear of obsticles. Luckly there were no cars following close behind us, if there had been the unnecessary and unexpected deceleration could have been dangerous.

While driving the vehicle on a 2 lane highway in sunny conditions, the vehicle suddenly braked while using cruise control. There was no traffic on the road ahead, no oncoming or traffic in my lane. Car slammed on the brakes slowing from 55 to 30 in about 2 seconds. If there was a vehicle behind me this would have caused a serious accident. This is NOT an isolated incident on my vehicle. The exact scenario has been reported a multitude of times by other people. This will kill someone and needs a recall. This is the standard equipment cruise control provided on all Tesla models. This isn't self driving or any other advanced feature. This is a critical issue that needs to be resolved.

The contact owns a 2021 Tesla Model Y. The contact stated that while entering or exiting the driveway on an incline, the automatic braking system engaged and locked up the tires in icy conditions. While reversing, the contact noticed that he was unable to turn off the integrated braking feature. While driving the brake pedal was depressed but the vehicle failed to brake efficiently. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 1,500.

Mileage: 1,500

There are multiple issues: 1. When trying to back up slowly, or move forward slowly, the car goes automatically on park "to prevent roll". I am intentionally trying to slowly back out of parking, and the car keeps stopping 2. When I try to change lanes, in many cases the car gives a solid "beep" which is equivalent to me almost crashing to another car. But there are no other cars! 3. The car keeps giving forward collision warnings when there is no immediate danger to collide with anything, and in most cases there is nothin in front.

The contact owns a 2021Tesla Model Y. The contact stated while driving 65 MPH with the cruise control activated, the vehicle independently and aggressively slowed without driver input. The vehicle then accelerated independently. There was no warning light illuminated. The failure occurred approximately 10 times. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 65,000.

Multiple "phantom braking" events while using adaptive cruise control (no full self driving, just basic adaptive cruise). First time while going at interstate speed and crossing a bridge, vehicle saw a shadow on the road and slammed on the brakes thinking it was a vehicle. Obviously this is a startling and dangerous situation especially for vehicles behind you. This has also happened on the highway, flat terrain, roads were clear of any obstacles and it slams on the brakes thinking there is something in the road. Every time it does this, there appear to be shadows on the road (from street signs, light poles, trees, etc.). The sudden braking is of course bad, but there's also nothing in the vehicle that tells you why, no chime, it just hits the brakes. It still appears that cruise control is active, but it won't resume speed after an event like this until you turn cruise off and back on again. I know this isn't an isolated incident and it absolutely will cause a crash, if it hasn't already.

It seems like this is a common problem if you search "tesla phantom braking," which very obviously needs a solution. I commonly experience the phantom braking when there is a shadow like passing under a bridge. The car will slam on the brakes thinking the shadow is another car, which is obviously extremely dangerous especially on the highway. A simple solution would be to add a legacy cruise control option, while fixing the phantom braking. This would cause a lot less wrecks and deaths.

On February 19, 2023, I was driving my 2021 Tesla Model Y on I-5 from LA to Sacramento on a clear afternoon. I was using adaptive cruise control (ACC) set at 78 mph, but not using auto-pilot, in the fast lane with a car following me. My car suddenly braked aggressively without anything in the roadway ahead of me. I then applied the foot brake and veered off onto the gravel left shoulder to avoid having the car behind me hit me. I saw in the rear-view mirror the following car swerve to the right to get around me, entering the slow lane. I believe that when I stepped on the brake, the ACC turned off and the car's automatic braking ceased. I then got back into the fast lane as there were no other cars approaching and resumed my drive. I didn't notice the speed my car had decreased to during the incident before I resumed speed, but I guess it may have been about 40 mph. Phantom braking happened one other time on I-5 on my way to LA from Sacramento two days previously (Feb. 17) also while in ACC, but there were no other cars around me and the automatic braking stopped when I tapped the brakes and I resumed my speed. In the year and a half we have owned the car, we have experienced approximately 10 instances of phantom braking, but fortunately, no accidents.

I have been driving long distance 418 miles today from Phoenix, AZ through Las Vegas, NV and north. In my 6 hour journey today my breaks were applied randomly by the computer around 20 or more times on autopilot and on cruise control. It is an extreme safety hazard. I want this on record because this is day one of a cross country trip and in case anything happens. The phantom breaking was so frequent in the last hour I could not drive with autopilot on anymore for fear of a car following me would crash into me at highway speeds above 65mph.

Numerous times we have experienced phantom braking when the cruise control is engaged at highway speeds. We think it occurs when you are close to cresting a hill and a vehicle is detected in the distance. The vehicle is quite distant, perhaps 500-1000 ft, but the auto braking system only see a short distance of lane lines (because they are out of sight on the other side of the crest) and interprets the vehicle to be much closer. This generally occurs about once every 100 miles of highway driving. Because of this, we are reluctant to use the cruise control. The date provided below is just the latest occurrence.

Experienced phantom braking twice today on I 5. Almost crashed or got rear ended. Car was on auto pilot. This needs to be fixed

Experienced phantom braking twice today on I 5. Almost crashed or got rear ended. Car was on auto pilot. This needs to be fixed

While driving on the highway at 70mph, on two separate occasions while using autopilot and cruise control, the car suddenly braked for no apparent reason. There were no vehicles immediately behind me at the time, however this was terrifying because I was scared that I was going to be rear ended at a high speed. I can no longer trust this safety system due it has happened twice randomly now.

SYSTEM MALFUNCTION: Emergency braking ("phantom braking") while set to automated driving/adaptive cruise control. OUR SAFETY PUT AT RISK: On a 2,000 mi. road trip from Denver CO to Tucson, AZ and back, the vehicle slammed on the brakes at 75-80 mph speeds over two dozen times. All incidents occurred either driving south on I-25 or west on I-10 going to Tucson, or on I-10 east and I-25 north on our return. By far the most dangerous event occurred when we were driving east on I-10 in SE Arizona on our return to Denver on 29 January. Driving in the right lane at 75 mph on a perfectly clear day with excellent road conditions, the vehicle suddenly slammed on its brakes. Following closely behind us was a semi-tractor-trailer, that also slammed on its brakes, blasted its horn, and very nearly rear-ended us. The truck driver then followed us at very close range for the next ten miles, If we slowed down, the truck slowed down. If we speeded up, the truck speeded up. We disengaged cruise control so we wouldn't involuntarily brake hard once more. Finally, the truck drive honked once more and dropped back as we sped up. In our view, this was an evident case of road rage on the trucker's part that might have ended tragically. REPRODUCTION OF PROBLEM: We have a 2/27/23 appointment with a Tesla service center here in Colorado to check out the automated driving/cruise control/camera and sensing system. However, this problem only arose under quite specific topographical, and road surface/light conditions on I-25 and I-10 in rural areas, so I'm doubtful Tesla service techs would be able to replicate the conditions. WARNINGS: There were no warnings emitted by the vehicle either audibly or visually (on the display screen) prior to any of these incidents.

The car brakes at highway speed with no safety hazards in sight. This phantom braking occurs while on cruise control or when using the accelerator pedal. We don't use auto pilot. It is very upsetting and could cause a rear-ending accident.

While driving on cruise control, the car slammed on the brakes out of nowhere. It was terrifying and we were almost hit from behind. There was absolutely no obstruction or any reason for the car to slam on the brakes. We do not feel safe having our young children in the car. We have notified tesla of the issue many times and they refuse to fix it. This car is unsafe and someone, a Tesla driver or members of the public on the road with this car, is going to be killed by the phantom braking . What is the NHTSA waiting for? Please force a recall. Clearly Tesla doesn’t care.

I was driving on a large, multi-lane, divided freeway (5 south Interstate just before Anaheim, CA in Orange County, California) and using adaptive cruise control (not autopilot) to maintain my speed in the mid 70s MPH. It was around 9pm PT and there was very light traffic. The next car in front of me was at least 100 feet ahead of me and there weren't any cars on the left or right of me. All of a sudden the car started decelerating really quickly, and by the time I pressed the accelerator to counteract the deceleration, the car was at roughly 60 MPH. There wasn't any indication as to why the car decelerated so suddenly, and there wasn't anything that I could see that might have caused the cruise control to react that way. Thankfully there wasn't a car close behind me - if there had been, it's possible that the trailing car could have hit me and caused an accident at high speeds. I've read online that there are quite a lot of reports of "Phantom braking" from Teslas, and from the descriptions I've read, my experience seems to be exactly the same. I hope that NHTSA and Tesla can work together to get to the bottom of this and prevent these types of scary incidents from ever happening again.

Jan 13, 2023 at 7:02AM PST. While using adaptive cruise control with lanekeeping, I was driving in second lane from the right at a constant speed. There was plenty of room in front of me- no car nearby. As I was slowly passing the car to my right, another car that was behind the car to my right began a normal lane change to its left into my lane behind me. For no reason, my car began to slow down suddenly. Video footage of cameras on my car show the moment when the front of my car pitched down because it was suddenly slowing down. The rear camera view shows when my car's brake lights illuminated for no good reason. I immediately intervened and accelerated back to my highway speed so as to not contribute to the car behind me running into me or having to suddenly brake itself and leading to a problem for yet more drivers. These video files I am linking to show the incident 14 seconds into each video. https://www.icloud.com/sharedalbum/#B0kGqkRUiGD9Mw9 I've experienced many examples of this phantom breaking since upgrading to 2022.44.30. I wish my car had a feature to enable simple, old fashioned, cruise control so I could use it on highways.

I was driving on highway 395 in California on Jan 6th in the afternoon. It was a very clear day. I was driving north on the 2 lane portion of the road north of Adelanto and Kramer junction with cruise control on set to about 72. With no cars in sight in front of me the car hard braked with no cars in front of me. I disabled cruise control and later enabled it again. It happened again. I contacted Tesla and they determined there no hardware issue with the car. I am afraid to use cruise control now in the car.

Multiple phantom brakes in a day with nothing in front of the vehicle on an interstate. Terrified drivers behind as a result.

Car sufferers from “phantom braking” and will aggressively brake while adaptive cruise control is engaged for no apparent reason. No “regular” cruise control is available to over ride this.

When driving with Autopilot enabled, the brakes suddenly and sharply come on when I crest a hill. It's very disorienting and could be dangerous if the road is busy. The Autopilot should not be beta tested on consumers and other drivers like this.

I have experienced phantom braking numerous times with this car so I plugged in an arbitrary date below. Fortunately it has generally been on rural, open roads where there was nobody close behind me, but there have been at least a couple of times where there were cars behind me and the braking came close to causing accidents. It is also terrifying when it does happen and has nearly caused me to lose control of the car more than once as I attempted to compensate for the abrupt braking. I understand that you are already investigating this issue with these cars so you know the details. Generally it happens when I am on 2-lane roads that don't have good dividers. The cruse control seems to mistake oncoming cars in the opposite lane as being cars in my lane and it will slam on the brakes. It also seems to be triggered by highway mirages and shadows. I have managed to capture the issue on video at least once.

Phantom braking

Tesla "Traffic Aware Cruise Control" occasionally unnecessarily applies brakes aggressively for no apparent reason when cruise control is in use. This presents a hazard to other driver's who may be behind the Tesla. This phenomena is well known to Tesla owners who have repeatedly posted about it in Tesla's Owners Forum. It is often referred to as "phantom braking". There is no option for the Tesla owner to disable the "Traffic Aware" aspect of Tesla's cruise control I believe Tesla could resolve this problem with a simple software update which would allow the Tesla owner to use cruise control normally without the "Traffic Aware" feature. The "Traffic Aware" feature is part of Tesla's problematic "Auto Pilot" feature. However, my Tesla is not equipped with "Auto Pilot". My Tesla is available for inspection upon request.

I was driving on the freeway, no one was near me (I had full control of the car, it wasn’t on autopilot) and the car’s brakes deadlocked while I was traveling high way speed and then made a sharp left turn which caused me to crash into the center divide and then hydroplane across the entire freeway uncontrollably

I had the adaptive cruise control (Autopilot) engaged on I95 and had it set to 60 MPH. Twice between a minute, the Model Y lowered the cruise speed to either 40 MPH and 25 MPH while on the interstate. No obstacles were in front of me to affect the cruise control system.

While in autopilot, the Tesla has been phantom braking repeaters. We noticed many time while driving at high speeds on the freeway, the Tesla model y will slam on the brakes for no apparent reason. There are no police reports

In Traffic Aware Cruise Control (aka Autopilot) car randomly changes the maximum set speed. This has caused a dangerous dramatic slowing of the car when highway driving. Car should not change speed setting without human input. I have video of this occurring.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 75 MPH, the vehicle inadvertently stopped without warning. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 1,600.

My Model Y applied the brakes suddenly when it was in Adaptive Cruise Control while I was driving in the interstate at 75 mph. This caused the vehicle to decelerate very abruptly. There was no vehicle in front of me and no obvious debris in the road. This happened several times on a trip from California to Kansas and back. On one occasion , I had just pulled back into the right lane after passing several tractor trailer rigs going 70 mph. I had to tromp on the accelerator to avoid being rear-ended.

Phantom Breaking. On Saturday -12/3/22, around 3.50 PM CST en route to Arlington on HWY 360, I experienced phantom breaking twice in quick succession. I was driving on autopilot at 70MPH and suddenly the car applied brakes and it was very scary to me and all my family. After the second event, I stopped using the pilot and drove with manual control.

On a long trip on I-70 across Colorado and Kansas I experienced 4 instances of "phantom" braking while using cruise control. I had set the speed at 78 and the car aggressively braked itself as if there was an object in the road when there was no object or reason to brake. In each instance if a car had been following closely they likely would have crashed into me. It also causes panic to the driver when the car aggressively brakes. I am contacting Tesla service today to report this issue and hope that it will be addressed but there has not been any inspection at this point. There was no waring or issues with the car prior to this and it has never happened to me before. It only occurred when using cruise control as I do not have full self driving and was also not using lane assist.

I own a 2021 Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, CA. Ever since, I have had more than 1000 instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. ​The experiences of severe phantom braking have been terrifying. The car often slams on its brakes for no apparent reasons on all highways and freeways, mostly where no cars or obstacles are present. I worry about getting rear-ended, which could lead to injury or death. My Tesla has been in for repair five times, and the technicians say they cannot fix it, that only a software update can solve the phantom braking problem They've been promising a software update since August 2021. After 16 months and five service appointments, I expect the problem would be solved by now. It hasn't. Please force Tesla to remedy this very hazardous safety problem. Let me know what you are doing to force Tesla to fix the problem.

I was driving about 65 mph on the highway with my Tesla 2021 Model “Y” in “Traffic-Aware Cruise Control” (not Auto Pilot) when, for no apparent reason, the car decelerated rapidly. This happened four times during a 1 hour trip from Boston to New Hampshire. No accidents occurred due to this incident but it was very concerning. This is not a new problem but it is occurring more often since the software was updated to include “Tesla Vision” instead of radar. I did not report this to Tesla because they are already aware of “Phantom Braking” issues with my model.

I was driving on highway when the car in front of me brake hard. Tesla failed to detect imminent crash and did not provide warning AND emergency braking. The vehicle has been recently serviced in tesla service center. There were no other warning lamps / messages / symptoms of the problem prior to the failure.

We were driving 65 miles per hour using cruise control on a flat road with no cars in front or behind us for hundreds of yards on both sides of a two-way highway. Suddenly, and for no apparent reason, our Tesla applied the brakes hard as though it was trying to avoid hitting an obstacle on the road. Within a second our speed dropped to about 30mph at which point our Tesla released the brake and accelerated back up to 60 miles and hour before I shut off cruise control.

When i was traveling at speed around 70mph on highway. Tesla has applied emergency brakes and locked the steering, which made telsa rotate(spinned) 3 times on its own and stopped.luckily no vehicles were near on either ways. The vehicle was all the way stopped on opposite road and I was able to start after some seconds it stopped and started my driving. No vehicles were near or nothing approached to apply emergency brakes. When contacted telsa they told to schedule service appointment and no help was given.

On many occasions while driving on a freeway near a feeder road the car automatically breaks by itself. I have come close to being rear ended several times. It appears the vehicle turns this feature on at the beginning of each new trip even after I have turned it off and the consumer must turn it off every time they begin to drive. I have also had instances of going around a bend and the car thinks it sees something, usually the barrier dividing traffic and breaks by itself.

I drove from Flagstaff, AZ to Las Vegas, NV on 10/26/2022. I attempted to put my car in AutoPilot (adaptive cruise control) around a dozen times during this 260 mile trip. Every 10-25 miles the car would brake extremely hard forcing the passengers to lunge forward as if the brakes were being slammed. In every case, the car was in the same lane (no lane changes) with nothing but open road ahead. In most cases there wasn't a vehicle in front or to either side of me (only behind me). No corrective messages or indications appeared on the screen to explain this action. The only corrective action I could take was to hit the accelerator to avoid a rear end collision. When I contacted Tesla about the issue, they checked the logs during this trip and found no faults in the system to explain this behavior.

UNKNOWN This incident happened on 10/16/2022 while on I-95 while the vehicle was engaged in the Auto-Pilot mode on the highway (We do not use this autopilot mode unless we are o the highway for long distance drives and that is very infrequent). The vehicle suddenly swerved around and lost control while on auto pilot. As always my hands were on the wheel and I could undo the auto pilot and take control of the vehicle. Fortunately there were no other vehicles around us and there was no damage! We have filed another claim previously with the NHTSA - 11455695

The vehicle is subject to phantom braking. When I use the adaptive cruise control and am driving in the middle or left lane (i.e. when there is a clear lane to my right), the car will brake when there is no car beside me. Sometimes this occurs when I am passing a large truck on my right. Last weekend, I was driving 68mph on a highway during a bright sunny day. There were no cars on either side of me. The car braked for no reason. I had to step on the accelerator pedal to get back to highways speeds.

Experienced phantom braking 6 times. There was no warning Automatic emergency braking system engages when there is no other vehicle around. Also experienced phantom braking with automatic emergency braking system turned off but cruise control was on, 2 times. Tesla shop replaced some type of coolant sensors and recalibrated mirrors but phantom braking still occurring. Technician took vehicle out on highway and did not experience phantom braking, and suggested more monitoring from me using "bug report" on screen to document incidents. Currently I avoid cruise control and automatic emergency braking system because of the potential of being rear-ended with rapid and unplanned slow down. This is a dangerous issue.

Phantom braking is common when driving on highway with advanced cruise control. On a recent trip from Tucson to San Diego I noted seven events in a 300 mile stretch. There were no cars within 1/2 mile in front of me, or any road debris during any event (I saved dash cam footage each time). There was a car behind me during one particularly violent event. I regularly commute on I-5 between San Diego and Irvine. One event per 70 mile trip is about the average. I’m almost used to it now.

While travelling on TX-130 legally at 85 miles-per-hour with cruise control enabled, the braking system suddenly and without warning self-engaged, greatly reducing the speed of the vehicle. System available for inspection upon request (however I can help). The sudden speed change at such a high speed is alarming to the driver, possibly provoking unneeded corrective action which could destabilize the vehicle. If another vehicle had been following even reasonably closely, a collision was very likely. A collision at such high speed is obviously very dangerous. Manufacturer has not been contacted, but such "phantom braking" is the subject of frequent news articles from various sites. No explanation for the cause of the braking was displayed.

While driving with cruise control set to 70-74mph, we had several incidents of phantom braking on a recent road trip. From 70mph with no obstacles, trees, structures, or other cars in sight, the car would suddenly brake itself. This happened multiple times, sometimes just a minute or so after the previous time. We were saved from being rear-ended only because the cars behind us were far enough back, but it was terrifying nevertheless. We cannot use cruise control anymore. Tesla must address this totally unacceptable safety issue.

I was returning home with my family at around 7 pm today (10/23/22). The autopilot (basic autopilot) was engaged and the vehicle was moving at 50 mph. Suddenly the car seemed to have engaged the brakes and I felt it almost came to a stop. At that time the red steering wheel alert appeared on the screen with the message to take control immediately. I had not braked nor there was a vehicle or any other object or vehicles in front of me or behind me. No vehicles were on the other lane either. The only thing I can clearly remember was a pickup truck waiting at a stop sign in a street connecting with the road I was on on the opposite side from me. Luckily there were no vehicles directly in front of me or behind me. It would have caused an accident if there was car behind me. All of us really got scared and my children are claiming they will never travel in my Tesla again. The vehicle may be inspected if needed. From what I read about this phenomenon it looks like what I experienced was a “phantom braking” event. The vehicle has not been inspected by anyone at this time after the incident.

I was going on I-95 North (Palm Beach County) on Autopilot (and I had Full Self Driving enabled in my car). It was raining, and I was at moderate speed, I would say 45-50 mph. The car started spinning uncontrollably. By miracle nodoby hit me, the card corrected after what I believe were 2 spins and continue on the same direction as traffic. I believe, with the nerves of the moment, that about 45 to 60 seconds later, I put auto pilot again, not knowing what hapened. And the car, out of nothing, started spininng again. 3 times, and I hit the opposite wall of the highway. By another miracle, nobody hit me (rush hour, I-95 north, 820am)

My wife and I recently drove cross country in our Tesla Y. Occasionally, we had the forward collision warning go off for no reason. More importantly, when we had the adaptive cruise control on and particularly when the autopilot system on, we experienced episodes of sudden braking when there were no other vehicles or other objects in the vicinity. This happened, on average, once or twice every 30 minutes. It got to the point where we had to keep the cruise control off because it seemed to put us in potentially dangerous situations. My car’s software is and was up to date. I contacted Tesla about this issue. They blew me off. Thanks. Steve Steinberg

The "Traffic Aware Cruise Control" and "Auto Steer". Yes, available for inspection. During driving on a long highway trip with these features turned on, the car suddenly braked severely for no reason(no objects or other vehicles were in front of car). This caused a large truck, which was following me to also brake and nearly collided with my car's rear. Repeat experiences like this "phantom braking" occurred. Based on other reports, this is common in other Teslas. No warning alerts in car.

While driving on freeway on a clear day with no other cars in front of me the car suddenly hard brakes such that one could feel the anti locking activating. I was lucky there were no cars behind me or it would have been vary dangerous. There was a car on my right but it was holding its lane and there was no visible reason for emergency braking.

When on cruise control, the vehicle frequently brakes hard at highway speeds, jerking our bodies and forcing cars behind us to brake hard as well. Sometimes this happens when we’re beside a semi truck or a car changes lanes far in front of us, but often there’s nothing. There is no warning prior to the braking.

I started a drive from my house. I entered a destination into the NAV system, it plotted a route. I then proceeded to start my drive. When I tried to backup, the backup cameras did not display any video, I waited over 1 minute and there was still no video. I then proceeded with my drive. The car would not start the cruise control, autopilot or FSD functions. Whenever I tried to engage the systems the car would state that they are unavailable. At this time, I also noticed that the NAV system was not updating the display, it continued to display the same image that showed that I was at home in the driveway. After 15 minutes, I pulled into a parking lot to video the problem. First, I put the car in reverse and recorded that the cameras did not display video for over 30 seconds, I then started to drive and recorded that the navigation display was not updating. The display that usually has the lane markings and displays the other vehicles was also not working, there was no information other than a picture of my car with a totally blank gray area around it. I have contacted Tesla about the problem, but they keep saying that they don't detect any problem with the car. I sent them the video and am waiting to hear back from them.

Phantom braking on 4-lane highway with no other vehicles near.

Vehicle was driving with auto steer enabled at 65 mph on freeway and braked unexpectedly and unnecessarily 3 times within a few minutes. Each time it occurred, I canceled auto steer and re-engaged. At no time were any obstructions or objects visible in front of the vehicle, and at no time did any warning lights or messages appear, the car simply braked without notice. Safety was at risk as cars behind me were traveling closely and were not expecting my car to brake suddenly, although I responded quickly enough to prevent further braking and accelerated out of danger. I have researched "phantom braking" and it seems this incident is exactly what was described in those reports. The car has not been inspected since the incident. I am hesitant to use auto steer since I do not trust that the cameras are adequately detecting what's in front of the vehicle.

Adaptive cruise control has failed many times. Recently had adaptive cruise control set at 75 mph on interstate. With no warning, the car instantly slowed to 55 mph. If a car would have been behind me I would have been rear-ended. Or worse, if someone behind me thought I was intentionally braking hard or "squating" they could become angry and instigate a road rage incident. The car provided zero warning before it braked. The car has not been inspected yet. Yes, the car is available for inspection.

When in autopilor mode (cruise controll) the vehicle ocassionally brakes for no known reason (phantom braking). This usually happens at the crest of hill if there is a guard rail. or if there is a low overpass overhead. I have reported this before (it is an ongoing problem) and discuss with Tesla representatives who reply that the car will "learn" to avoid this behavior. It is an obvious collision danger if someone is following closely. On 09/27/2022 this occured 8-10 times during a 600 mile trip

5YJYGDEE2MF161659 VIN 2021 Tesla Model Y AWD with basis cruise control This last weekend we drove from our home in Arroyo Grande CA to the Mammoth Lakes area. Enroute, we experienced a number of unneeded emergency braking events while on the highways at speed (65-72 mph). While this happened about a dozen time, 5-6 of them were significant slow downs and could have caused us to be rear ended. In none of these events was there any reason for the emergency braking. One happened when another car was approaching from the rear quickly to pass. These events led us to stop using the cruise control entirely for the last 2 hours of our trip home. I have not yet contacted Tesla about this which I will be doing right after I submit this report. Prior to this, the adaptive cruise control had functioned normally with very few unexpected emergency braking events in the last year or so. We did disable the feature of “automatic emergency breaking” but that had no effect at all. This is a serious issue that need to be addressed immediately.

I have not yet contacted Tesla about this which I will be doing right after I submit this report. Prior to this, the adaptive cruise control had functioned normally with very few unexpected emergency braking events in the last year or so. We did disable the feature of “automatic emergency breaking” but that had no effect at all. This is a serious issue that need to be addressed immediately.

My Tesla model Y has been braking for no apparent reason when using the adaptive cruise control. Sometimes there may be a car coming in the opposite direction, but most times there is no other cars within miles. Several times the braking has been extremely aggressive causing me to have to hit the accelerator hard to avoid somebody behind me running into me. This has happened many times on long,straight, flat roads in the middle of the Arizona desert.

Using normal cruise control in the highway, my car brakes randomly and suddenly. This phantom braking has happened over 10 times in the past two weeks! It's very dangerous.

The vehicle brakes for no apparent reason without any other vehicles in near vicinity, both in adaptive cruse control and autopilot. This has improved with updates, but on a recent trip we experience six phantom breaking events on interstate travel.

Vehicle is experiencing “phantom braking”. Has happened dozens of times. I have contacted Tesla a few times regarding this, and they downplay everything.

While car was on cruise control. The car went off cruise control without intervention or warning and slowed down quite abruptly. This occurred about 4 times in a 4 hour period while going interstate speeds.

Tesla's Traffic-Aware Cruise Control system has malfunctioned on my vehicle several times. It will often brake hard at high speeds despite there being no vehicle or object in front of me.

Multiple incidences of phantom braking while using cruise control/autopilot (not full self driving) traveling to/from Sacramento, CA and Park City, Utah on August 13th and 19th. This has happened previously while traveling to/from Sacramento, CA and Napa, CA. Unexpected hard braking on the highway at speeds of 55-85 mph) for no apparent reason is a hazard to the driver/passenger as well as any nearby vehicles. It causes undue fright, motion sickness, whiplash, and potential accidents. I contacted Tesla and they evaluated the car remotely and said they found nothing wrong. Yes, the car is available anytime for an inspection. No, the car or components have not been inspected by anyone, except as noted above by Tesla's service department. There were no warning lights/messages. This has been a problem for at least 6 months. It just became more evideent on our trip to/from Utah.

Traveling at 80 MPH using autopilot on an open freeway when suddenly a phantom braking event occurred and slows us down to 50 MPH in 5 seconds. There were no objects on the freeway and the closest car in our lane was at least one mile in front of us.

The contact owns a 2021 Tesla Model Y. The contact stated that while her husband was driving approximately 75 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle inadvertently slowed down to 30 MPH. The contact disengaged the cruise control and the self-driving feature also disengaged simultaneously. The manufacturer was made aware of the failure. The Service Center diagnosed the vehicle with a software failure however, there was no current fix. The failure mileage was 10,043.

I was driving my Tesla Model Y using “navigation with autopilot” on 9/4/22, from San Francisco to San Jose. The vehicle suddenly stopped while traveling at high speed after crossing “green” metering light in the ramp from 237 to 880S. The vehicle behind had to make a sudden stop, barely avoiding a rear end collision. This is the 4th time I have experienced this “phantom braking” while traveling at high speed on freeways.

During a drive on 09/06/222 the car had 3 instances of phantom emergency braking while using autopilot. All the times there were no cars around the Tesla, the stop was a hard brake that jerked passengers around as well as shifting cargo. This has happened periodically before but now it is become common on every drive. Two of these instances occurred with in minutes of each other. The other happened later in the drive after stopping to charge. A hard stop like these could cause a serious accident if someone is following to close. These hard brakes could also cause whiplash style injuries, seatbelt abrasions, or bruises to passengers. There were no warnings, messages or sysmptoms prior to the issue.

During daylight hours when the autopilot is engaged at normal highway speeds - the Tesla brakes engage and quickly slow down the car. It occurs on long straight roads with no traffic. This appears to be a "phantom braking" issue that is causing my car to suddenly brake for no reason. There are never any cars around when this occurs-- just long clear roads. This can be very dangerous. Last known occurrences were on Aug 13 at 8:30a and 10:29a of this year.

I have experience phantom braking on my Model Y many times when I used FSD(full self drive) on the freeway. The car just randomly slows down / decelerates abruptly even if there are no obstacles or other cars in front. This results in a serious situation when the vehicle behind may ram into you causing a fatal accident. I have always reported this issue using voice control REPORT BUG and got acknowledgement saying THANKS FOR THE FEEDBACK. But I have never heard from Tesla that they have fixed or are fixing it. This is repeated happening every time I use FSD on freeway even as of last week (week of Aug 21, 2022)/

Frequent, random, phantom braking using cruise control. Informed Tesla with times +/- one minute. Sometimes the braking was very hard and could cause a rear-end collision (at highway speeds). Always occurred with no warning and highly variable conditions (light, or hills, or overpasses, and then apparently nothing). I called Tesla and technician said overpasses were a problem. Vehicle and components have not been checked.

I had unexpected and sudden braking while using Tesla autopilot while in TAC mode or adaptive cruise control. Not Autopilot that steers and keeps you in the lane and not Full self driving, my car does not have FSD. I had 5 or 6 incidents while heading West on I 10 towards Yuma on I 8. There was no rhyme or obvious reason for the braking. No one in front of me or behind me. The amount of braking over the separate incidents was different each time. On the way back to Tucson it happened another 5 or 6 times.

Tesla Autopilot (Adaptive Cruise Control) rarely recognizes parked vehicles or obstructions beside the driving lane (right or left side) based on the display console driving environment display. Bicyclist, pedestrians, and other large roadside obstructions are also rarely recognized. Might explain the recent Tesla collisions with stopped emergency vehicles while in Autopilot mode. Don’t know if Teslas recent elimination of radar sensing made this problem worst or not. This failure to recognize nearby obstructions happens daily.

I own a 2021Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, Ca. Ever since, I have had numerous instances of abrupt automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. On January 26, 2022, I had 47 episodes, in just a couple of hours. This is typical. Several of the phantom braking episodes occurred with vehicles tailgating me. This is a grave safety issue and requires immediate attention. My Tesla Model Y has been to the Tesla service center over 4 times regarding this problem without resolution. They say phantom braking is a software issue and only the engineers can fix it. I was assured soon after delivery that the software would be updated quickly, and it would fix the problem. The issue still exists. I am very disappointed with the vehicle and fear for my safety. Please require Tesla to remedy this very serious safety issue immediately.

Autopilot was on during a light rain event where I was traveling less than the posted speed limit on the I95 northbound Highway. The autopilot appeared to force the car to abruptly jolt the steering wheel/tires, causing a slip/ hydroplane of the front end which forced the car into a left/sideways slide across the highway. The car slid sideways for about 100 feet or so before going straight into the concrete divider along the Highway (front driver side initial impact, then rear driver side 2nd impact). Control could not be regained with the vehicle. Steering did not work (tried to correct the path), it felt as if brakes did not slow the vehicle as the car approached the divider. Autopilot was fully engaged and lane keeping was active… with at least one hand on the steering wheel and moderate level of attention to the road. I must say I had likely became over-reliant on the autopilot. No warning was provided to me as, prior to the incident. A similar hydroplane problem can also be seen on a YouTube video posted online for the same model car. I experienced the same outcome as the other vehicle except I hit a divider after crossing lanes. I am however very pleased with how well the car handled the impact and how well the airbags went off, although also unfortunate- I do feel like the car may have been partially responsible for the accident itself.I have experienced a few prior occurrences where the car will jerk the wheel when in autopilot to keep or find a lane, even with hands on the wheel and full attention facing forward.

multiple incidents of phantom braking well traveling on I 90. 5 documented incidents. Have requested vehicle service however previous service for this type of incident did not correct the issue. at one point the car slowed from 75 to 50 before i could react. there were no other vehicles near my vehicle when the events occurred.

While driving cross country on interstate highways using cruise control my car would try to stop itself. During a 500+ mile day it would do this 10x per day. Most times hard enough to engage seat beats. There has been no inspection. Tesla is denying a problem. The danger is if someone is following too close they could resend me. I was never in traffic when this happens. Never anyone in front of me or next to me when this happens. On line they call the phantom braking. I can’t tell if it’s braking, or the cruise control disengages and the car is suddenly stopping because of one pedal driving mode.

Currently and noticing other reporting the inaccurate location of the GPS in the car. At times the car gpe will drift into areas not associated with the cars correct location. If the car is in adaptive cruse or teslas autopilot the car will maintain the posted speed limit for that GPS location or a delta of the users defined (+ - 10 or 15 mph). This cause a car to abruptly reduce the speed if not within the posted speed limit for that area. For example a car in autopilot or adaptive cruse going 70mph on the highway, the gps will start drifting into areas outside of you location and abruptly reduce the speed to assumed location. This is even more troublesome if autopilot is engaged where the car will try to change lanes as directed by the gps.

My wife and I have owned the Tesla Model Y for one year. We have taken it on several long distance drives from our home in Moscow Idaho to the Oregon and Washington coasts, Vancouver BC and Seattle. During each of the trips we experienced phantom braking when the car was driven with cruise control engaged at highway speeds on 2 lane highways. Phantom braking has occurred when 1) there was no oncoming traffic during daylight hours 2) with oncoming traffic that was not in our lane 3) when there was a slight turn in the highway and no traffic. The most recent phantom braking events occurred 7-14-22 and 7-30-22 on Washington highway 26. When the phantom braking occurs it appears to be random. The car will very quickly drop from 65mph to 55mph causing us a scare. We do not use the cruise control feature anymore on the two lane highways. Its just too scary when it happens. We have complained to Tesla and have submitted service requests and was told they are aware of the problem but no corrective action has happened yet.

We experienced 3 phantom braking events while using the autopilot feature of the Tesla model Y on our trip from Los Angeles to San Francisco. While on autopilot on the 5 freeway northbound, the car just braked when the lanes in front of us are clear.

Reporting numerous instances of ghost braking while Adaptive Cruise Control is enabled. These are instances of sudden deceleration of the car when no other vehicles or obstructions present while traveling on 4 lane highways at freeway speeds. Requires overriding ACC feature by engaging the accelerator to maintain speed and avoid a possible rear end collision. Rear end collision is the most of the highest risk when this sudden deceleration occurs. No warnings were given before the deceleration. These episodes are most noticeable when traveling at freeway speeds of 65+ mph in open terrain with no curves. One instance could be attributed to a shadow across the roadway, however, more times than not shadows across the roadway didn't cause ghost braking. The point being that there often is no rhyme or reason that can be identified or repeated. This problem is a known problem that Tesla is aware of as well as the NHSTA.

While driving at highway speeds the adaptive cruise control suddenly slams on the brakes for no reason. It is more frequent when there is little to no traffic. This happens regularly, it is not an isolated incident.

On October 12th, 2021 my vehicle had multiple instances of phantom braking that occurred on highway 10 in California while traveling Eastbound with autopilot engaged. This was a trip in excess of 400 miles. Two of these instances occurred as my vehicle approached rainwater washes where metal barriers appear on both sides of the road ( see 33°38'10.5"N 115°05'01.6"W for an example ). The third instance occurred when a truck in the slow lane began drifting towards my lane slightly. In each of these three instances the car did a heavy braking at which time I quickly disengaged the autopilot by tapping the brake and speeding back up. Thankfully no accident but these three occurrence were scary. I reported phantom braking into the voice command database of the vehicle after each occurrence. According to a tesla representative these are saved.

On multiple occasions the vehicle in question exhibited dangerous behavior while the "Autopilot" cruise control system was engaged. This is not "fully automated cruise control FSD" but the standard "Autopilot" system. Each of the incidents listed below occurred on multiple dates, multiple times and in various times of day, speeds and weather conditions. 1. While driving at speed, the vehicle, upon detecting the cars in an adjacent lane separated by pole dividers were stopped, suddenly slammed on the brakes in an attempt to stop the car, risking a collision from behind, even with my own lane completely clear of other cars 2. While driving at speed, the vehicle, upon detecting a higher or lower posted speed limit sign alongside the road, suddenly braked or accelerated without warning, risking a collision in front, or behind 3. While driving at speed, the vehicle, upon detecting emergency flashing lights from a passing police, ambulance or fire vehicle, regardless of that vehicle's location or direction, suddenly decelerated without warning, risking a collision from behind 4. While driving at speed, the vehicle, upon detecting a change in lane width, the loss of a lane marker, or the presence of a concrete barrier in place of a lane marker, suddenly swerved to attempt to remain in the center of the changed lane width, and on more than one occasion, almost swerved into a barrier or another vehicle

A. 3 or 4 times while I was driving on the highway with cruise control the car very suddenly de-accelerated even though the road ahead was completely clear. This happened before. B. Also later on the same trip the car hit a part of a tire tread left on the road. The underside of the car was apparently damaged. The screen message was "okay to drive. power reduced". Over next several hours the power, and later other functions like air conditioning, and maximum speed was reduced from 69 to 67 to 65 to 62 mph and message "okay to drive" was repeated. Suddenly while car had message of 62 mph maximum speed it suddenly wouldn't go over 37 mph. Seconds later it dropped to maximum 13 mph while still showing "okay to drive - 62 mph max speed". I pulled over on shoulder and car wouldn't go into drive function.

While in cruise control, which is adaptive, vehicle will abruptly slow down for no know reason. Usually there are no other vehicles, no highway obstructions, nothing that I can see. Tesla finally told me that this is a "known issue", after making a service appointment, and them calling me to cancel the appointment.

Car regularly brakes for no reason causing near accidents constantly and posing a huge safety risk. Additionally, the full self driving option is totally unusable. Both these issues have been reported to Tesla multiple times. We have been told the only way we can have an actual working cruise control is to disable the full set aware driving without refund for that Bert expensive option

The driver infotainment system locks up randomly. Which makes all safety features, turn signal indicators, backup camera, reverse mode (mirrors drop), speedometer, collision sensors, etc NON-FUNCTIONAL. Until either the system crashes or finally unfreezes. This also removes one-pedal driving as well when frozen. Version is 2022.16.3

While using adaptive cruise control we have experienced multiple incidents of our vehicle braking hard, fast, without warning, and for no reason. The most recent incident just happened (07/21/2022) while driving on a 4 lane highway. My husband was using ADP traveling at approx 65mph when suddenly our Tesla model Y began rapidly braking, throwing my upper body towards the dash and causing us to almost be rear ended by the vehicle traveling behind us. Thankfully, I did not hit the dash and the vehicle behind us was paying attention and swerved into another lane to avoid a collision.

The vehicle loose power all of sudden while driving disabling all power including loss of power steering, failure of lane departure avoidance, regenerative brakes, parking breaks, traction and stability controls. This has caused hazardous dangerous conditions on the road. The vehicle had to be towed to local Tesla repair/service center on 4 occasions. We have been given false reassurance with no definitive fix yet, continues to be an ongoing issues that recurs after few weeks that vehicle comes back from service center.

On July 16, 2022 I was traveling west on I-40, east of Tucumcari, NM. I was using Traffic Adaptive Cruise Control (TACC). There were no cars within a mile of me, front or back. The weather was clear, the road was flat. The car suddenly braked without warning. The objects stored in the back of the car flew forward, striking the two front seats. The wheels did not lock up. I immediately stabbed the accelerator. I saw the power line bar graph indicator go fully to the right. I contacted Tesla to request a service appointment. Tesla initially set an appointment but then cancelled it, explaining there was nothing wrong with the car. I was reminded that TACC (along with virtually all other Tesla driving aids) is "beta" and may therefore not function as intended or expected. It was the responsibility of the driver to assume the risks implied. Prior to this event, I had already decided not to use any technology more advanced than the speed control (TACC) as they behaved poorly. I thought that adaptive cruise control (Tesla: TACC) was a such a common technology that it wouldn't exhibit phantom braking. I was wrong.

I own a 2021Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, Ca. Ever since, I continuously experience automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. It is very dangerous because I almost got rear-ended. I've had it in Tesla's service center several times for inspection. They always say the technicians can't fix the phantom braking problem, that only the engineers can, and that they are working on it. It's been one year and there hasn't been a software update to remedy the dangerous flaw. Will you please force Tesla to fix the hundred, perhaps thousands, of Tesla Models 3 and Ys that have this problem? An investigation and recall would be welcomed. Thanks!

On a roadtrip between California and Wyoming, the adaptive cruise control, full-self driving, and emergency breaking engaged for absolutely no reason on dozens of occasions - what I understand is termed "phantom breaking." This was so bad that on Sunday, July 10, I noted each severe incident. Some of these occurred with absolutely no traffic in the road, some during busier periods. In each case, it was scary and dangers -- to the point where my dog went flying off the seat. While this was an issue throughout the road trip, I only noted incidents on July 10, but please be aware this happened on many other days as well. Here are the significant incidents on July 10. Please note there were less severe incidents on this day that I didn't note because it would have been too many to count. 12pm mountain time just outside Idaho Falls, ID -- car braked with no warning from 70 MPH to 60 MPH 2pm mountain time - 77 miles outside twin falls, ID 256pm mountain time - right outside twin falls 408pm mountain time - heading south from Twin falls towards Nevada -- the car braked three times in rapid succession 447pm mountain time - heading south past Jackpot NV 450pm Mountain time - same 420pm Pacific time - 16 miles north of Wells NV, braking multiple times in succession 524pm pacific time - just west of Wells, NV, sudden braking from 85 mph to 65 mph 643pm pacific time - half way between Wells, NV and Winnemucca NV

The vehicle was on cruise control (NOT auto-pilot). Driving on Freeway approximately 82 mph when the vehicle slowed to 60 mph instantly numerous time within my 160 mile drive. There were no vehicles in front or beside me. There were no obstacles in the roadway or on the side of the road. Sunny day with no clouds. There were no warnings lamps or messages that would indicate the car was going to brake. My safety was put at risk if there was another driver behind me, I could have been rear-ended. It Could also had been very dangerous if there was adverse weather. Tesla was not able to recreate the problem and never found any problems with the vehicle. This was not the first time we took the vehicle in for phantom braking. Tesla blamed the driver. I was also told by a tesla representative the the vehicle can brake unexpectedly by sensing a shadow on the road from a cloud. Apparently there is no way to disable this feature. The vehicle has been deemed unsafe to drive by our senior management as this is not the first time this has occurred and Tesla has not remedied the problem.

While adaptive cruise control was engaged on highway, it would disengage and harshly break even though there was nothing ahead as an obstacle. If there was a vehicle behind, it would have created a significant change of collision. During a 5+ hour drive, this occurred 20+ times. It seemed to occur when cresting small hills where visibility was somewhat limited ahead and when there were few cars ahead. In a few occurrences, there was a warning chime, but in other cases, it disengaged and braked silently. This just happened yesterday, so it has not been inspected by Tesla.

My car is experiencing phantom braking nearly every time I use cruise control. It only happens when there are no cars or other obstacles in front of me. It happens at various speeds. The braking slows the car to a stop within seconds if I don’t immediately disengage the cruise control, even at highway speeds.

Going 40 MPH on CA 210W in left lane. Full Self Driving available on vehicle but no autopilot/lane assist activated at time of incident. Steering wheel locked up completely; I was unable to turn the wheel at all so I ended up drifting across 4 lanes of highway (miraculously didn’t hit anyone) and ended up under a semi. Car airbags did not deploy and system did not detect a collision. Contacted Tesla to ask about the cause of the accident multiple times; never got an answer. They had us pull the USB in glovebox and see if anything is on there but there wasn’t even though dash cam was activated. They “escalated” the ticket to a supervisor and have been ghosted ever since asking for an answer. We scheduled a service appointment to have them check out the vehicle and they canceled it. It is a miracle that I did not die; I have severe PTSD from the incident which has affected my career negatively. I would like Tesla to take accountability for things like this; it’s scary that they don’t and threaten legal action instead.

Phantom braking during normal highway travel at high speed, multi accuracies in one trip. The braking made vehicle travel speed dropped from 70MPH to 50MPH suddenly and pose great danger.

I was driving on I5 north with autopilot enabled at 75 mph and the car decelerated rapidly to 45 mph. There could have been an accident if someone were behind me.

I own a 2021Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, Ca. Ever since, I have had thousands of instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. On January 26, 2022, I had 47 episodes, in just a couple of hours. This is typical. My latest incident of phantom braking occurred on June 27, 2022. In August 2021, I was promised by Tesla that a software update would be issued soon to remedy the problem. It still hasn't. I'm very exasperated. I understand Tesla was supposed to give you information about this issue on June 20, 2022. I am anxious to hear about Tesla's response. Furthermore, I sincerely hope the Tesla has told you they are fixing the problem. Has it? Please let me know of updates and proposed fixes to Tesla's phantom braking.

Driving on major interstates across Idaho, Wyoming, and Utah, there were several instances of so-called “phantom braking” — while using Adaptive Cruise Control, with no other cars or obstacles in front, the brakes were rapidly applied, decelerating the car from roughly 75 MPH down to around 60 before I could manually press the accelerator pedal to override the behavior. Not only is this dangerous for myself, but could easily cause an accident if people are following closely at highway speeds. If Tesla’s camera-only system (as opposed to radar) can’t do the job, they should at least provide an option for a non-adaptive cruise toggle that would hopefully work around the issue.

We just completed a 6500 mile round trip road trip from So Cal to Toronto Canada and back. 5/24/22-6/12/22 During the trip we used the "Auto Pilot" with and with out "Auto Steering" Not Full Self Driving. I lost count of how many times we encountered "Phantom Braking" with the car at highway speeds. My guess would be at least 50 times. It got to the point where I would not use Auto Pilot especially when there was heavy traffic at full highway speeds. My deduction on why this is happening is that the Tesla cameras are "Infrared" sensitive and it seemed that the car was applying the brakes when it would see the heat waves off the hot road surface. Also in early morning one day the sun was directly behind us and the cars shadow was directly in front of us on the road surface and it kept applying the brakes thinking it was another car. In slow moving bumper to bumper traffic going 30MPH or less does not seem to initiate the "Phantom Braking". But at highway speeds it is super scary and dangerous when this happens. ;(

The vehicle randomly applies hard brakes. This makes cruise unusable and presents a safety issue for cars behind. I was almost hit from behind when my Tesla applied brakes on interstate going from 65 to 35MPH.

-Auto pilot (adaptive cruise control). Yes it is available for inspection. -Vehicle unexpectedly slowes down on highways (when using cruise control) at an unsafe rate when there is nothing in the path of the vehicle. This has cause multiple instances of vehicles almost rear-ending me due to the rapid deceleration. -I have asked a Tesla Service Center representative about the phantom breaking and they stated it was a known issue and that was being worked on. -No, the vehicle was not inspected by the manufacturer since we were advised it was a known issue. -There is no warning lights or sounds before the vehicle suddenly brakes. I suspect that hills, shadows, on coming traffic on two lane highways are some of the causes for the phantom braking.

There are 4 issues to report for our Tesla Model Y: 1) On the highway, our Tesla often presses on the brakes and slows down by itself when it should not be doing so. This occurs when we have adaptive cruise control on. We’ve noticed that at the time of the slowdown, the Tesla misreads the highway speed limit. For example, the Tesla will read the speed limit as 70 mph, then all of sudden without warning, the Tesla will suddenly read the speed limit at 40 mph, which then causes the Tesla to break and slow down by itself, when the speed limit is actually still 70 mph. This can happen several times on a single highway trip. Aside from the shock we receive as a driver as our vehicle slows unexpectedly, this could cause a rear end collision if a car is following us too closely from behind. 2) When we use adaptive cruise control and the steering assist feature, the car does not recognize to slow down on highway off ramp curves. I monitor the speed around curves, though if a driver is not aware of the issue and expects for the Tesla to take the curve slowly, this could cause an issue. In particular, if there is a big curve, I’d be concerned of the Tesla losing control and going off the road, due to speed. 3) The car will often provide a frontal collision warning, even if there is no car or object in front of the car, while it's in motion. This can lead to confusion for the driver or possibly hard breaking, which could cause a rear-end collision, if a car is following too close behind the Tesla. Also, the Tesla driver may swerve unnecessarily to avoid an object that isn’t there, which could cause a collision. 4) The Tesla is advertised as being able to travel over 300 miles on a single charge, however, the conditions for this to happen seem incredibly difficult to meet, as mileage is usually far less than this. This can cause drivers to overestimate how far they can drive, which could lead to cars urgently pulling of the road to prevent stalling where traffic is.

This is my sixth complaint to you. I own a 2021Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, Ca. Ever since, I have had several thousand instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. On January 26, 2022, I had 47 episodes, in two hours. This is typical. I was told immediately following my purchase last August that there would soon be a software update to remedy the problem. There hasn't! I have had five appointments with the Tesla service center, and they continually say "we can't fix it, only the software engineers can". The braking episodes are dangerous! I implore you to hold Tesla accountable and demand they fix the problem immediately. PLEASE!

I was traveling early morning before sunrise over the tehachapi pass towards Mojave in California. Someone had lost a camper shell from the top of a pickup truck in the lane. It was still dark outside. I saw the obstruction in the road but the car cameras did not pick it up. I pulled into the left lane to try to get around the camper shell. The lane assist pulled me right back into the camper shell which tore down the side of the car doing 10k in damage. The car never recognized impact or an accident. I have the videos from the cameras of the car. The lane assist, as far as I know, only doesn’t activate when the turn signal is used, which I did not have time for, as I had less than 200 feet between me and the camper shell.

Several instances of emergency braking applied without warning or obvious need during multiple driving sessions. This results in an unexpected rapid vehicle deceleration. Fortunately no other vehicle was following close enough to represent an imminent safety hazard though it is easily plausible this could happen. Typically the issue occurs when traveling uphill or around a bend and encountering traffic in an oncoming lane, structures (bridges) or dark shadows. The unexpected emergency braking has also happened when adaptive cruise control or autopilot is engaged while overtaking large vehicles on the left (tractor trailers in the right lane). I have also noticed several erroneous lane departure warnings despite turning off these notifications on the dashboard. They are more a nuisance than safety hazard so far but would like to completely silence them entirely. These issues have yet to be reproduced or inspected by the dealer, police, insurance or other investigator. No warning lamps or indicators were active at the time the braking or lane departure warnings were observed.

I was driving to and from mammoth lakes California. Middle of the day, clear weather, with no other cars within thousands of feet if me. I put my vehicle into adaptive cruise control (not autopilot) and several times during the drive the brakes would slam to the point of reducing my speed from around 70 mph to roughly 40 mph very quickly. It was extremely happened and was repeatable but with no known reason.

When autopilot, it’s sudden breaks with no reason. My wife got neck injury.

Unexpected and rapid slowing/braking of vehicle since new in November of 2021. Occurs when on cruise control usually at highway speed, more often on open highways and have possibly (though not always) related it to cresting a hill, distant reflective “water mirage” on our western roads, passing large trucks, two lane highway having large oncoming trucks +/- on curves. On one occasion while passing a semi truck with car on my tail came within a foot or so of being rear ended. Many other occasions where got to point I do not feel safe using the cruise control. We have driven it from Denver to Tucson in November and back in May, both times was worse on wide open western roads, sometimes tho not always with bright sun, pretty unpredictable and random but often to point of not using any of our autopilot or cruise control functions with confidence of safety. No warnings, lights or prehappening signs. Reported and examined in Tucson on arrival there in Nov/21. Told would “get better with time” and further hardware updates. Hasn’t happened with city driving (tho rarely use cruise control. Happened a couple times on highway drives in Arizona while on cruise and thought maybe better until recent trip to Denver when it was as severe as November. Again contacted Tesla and told would lengineers are aware of problem and would be fixed with hardware app fix at end of June. Recontact them in July if still an issue. When serviced in November for this issue tech said he could see in computer log what was happening. When I set up appointment this time basically said live (or die) with it until June and nothing they could do til “hardware fix”. In blanks below I entered last episodes date. It has been ongoing from 11/2021 to present at speeds from 50 to 80 mph. Started with first trip when less than 300 miles til present 5436 miles on it. Could almost guarantee it would happen on highway trip with cruise control if you would like to risk your life on a test drive.

The vehicle braked and slowed down on the highway for no reason when on autopilot. The speed of the vehicle was around 55 mph when suddenly it stated to decelerate for no reason. Ot resume speed after 100 ft or so

This is a supplement to NHSTA Safety Issue ID 11467902. I requested service from Tesla. Attached is the service center's response writing that it is software subject to updates. This is unacceptable to me as the car is not driveable with this safety issue.

The vehicle phantom breaks spontaneously upon an interstate drive for 1.5 hours on cruise control it will slam on the breaks between 3-5 times when there is no car or object near the vehicle. This has been reported to Tesla and they do nothing and pose no solution to the problem. It is dangerous and going to cause accidents.

Recently, I had a long distance trip and and Tesla Model Y braked the vehicle at highway speed when it was on Advanced cruise control 3 or 4 times with obvious reasons. I had to push the acceralator pedal to speed up in order to avoid rear ended collision in a bumper to bumper traffic.

The car had a phantom braking incident where I was on the freeway with the autopilot set and the car slammed the brakes on because it thought it saw a person in the freeway. This is what it showed on the screen. The car decreased the speed from 70 mph to 40mph. There was no notification of this decrease. This has happened before in the car, but not as drastically and it doesn’t happen very often.

I have been experiencing that my Tesla suddenly automatically slammed on the brakes while it’s on self driving mode on highway specifically I-66 and while returning from my work from Nebraska Avenue complex to Ashburn VA. This automatically phantom braking is very dangerous.

During 350 miles of driving, I experienced over 35 phantom braking events. Most were while driving at 75 mph. Some were while driving 45 mph. It did not matter whether I was in Autosteer with cruise, cruise alone or driving manually. I turned off Emergency Braking on the screen. I still had incidents. Some incidents were severe to the point that I could feel the ABS. There were no other cars, structures, signs etc. in the vicinity. Had there been a semi following me, there would have been an accident. If another car, I could only hope that they had traffic aware cruise and emergency braking. This is unacceptable as it is so dangerous.

Driving on I-43 in Wisconsin on June 2 around 2pm CDT while in cruise control the car suddenly went into emergency braking and slowed down dramatically requiring me to override the system. There was very little traffic and a semi-truck about 200-300 yards ahead of me.

The brakes engage during lane assist mode as if to avoid something in the road although there is nothing there. This happens many times on a road trip from Phoenix to Los Angeles on I 10. It also happened multiple times on the freeway in town in Phoenix. It is very jarring

Phantom braking. Had car on cruise control and FSD and car would brake excessively for no reason.

I was driving on Auto pilot and with no obstacle in sight or the need to do so, the car AEB system get activated ( PHANTOM BRAKING) another complaint that I got is went the traffic lights changes to green and I'm on Auto Pilot and the car slower down on the middle of crossing that intersection that can create an accident because the car from behind do not expect you slower down, the AEB system get activated went it's nothing in front of you.

For the last several software versions, the car experienced “phantom breaking” when on a high speed roadway with no apparent obstacles in the road.

The car suddenly stops as if the traffic ahead is stopped. I noticed it happens when the auto pilot is on. I gave up using the autopilot because I have experienced the sudden break and I have missed having an accident. It kind of feel like the sensors from the sides get the idea that if the side lane is going slow the car has to break suddenly.

Driving on I95 in Florida. Cruise control engaged at approximately 70 mph. Problem: sudden braking without my stepping on brake pedal. Car started slowing down immediately and veering to the left almost out of lane of traffic. I immediately pressed accelerator and avoided any collision. This happened 3 times to me, always on I95 where I do most driving, always with cruise control engaged.

While the car is in “autopilot” (we did not pay for full self driving package), the car will apply braking often while at posted speeds on interstates and highways in Montana, Idaho, Nevada, California, and Utah. Our observations notice it happens when the road color transitions between older and newer road surfaces and in curved sections of roadway (especially curves to the left). We are looking for a replacement electric vehicle now due to this problem.

My Model Y Tesla, while driving on the freeway using full self driving, would abruptly slow down from 70mph to 40 mph in matter of seconds without warning and luckily there was nobody around me. I did a bug report on it many times but Tesla discounted that. Also my front windshield wipers would come on for no reason even on a sunny day. Sometime on a raining day when going into a tunnel the windshield wipers would stop and would not come back on when I get out of the tunnel and that is really scarily as I was unable to see during heavy rain. I had to manually turn it on and that took a few seconds and in the meantime I could not see anything due to heavy rain. I brought this to Tesla and they told me that the windshield wiper control and the headlight use the same sensor and there is nothing I can do except to place the windshield wiper on manual mode. The rain detection wipers are on many different model cars without issues. I am not sure why Tesla could not add an additional sensor just for the windshield wipers.

While using the autopilot (not full self driving feature) on the highway, I have experienced multiple inatances sudden braking for no reason. No vehicle has been in front of me in these instances and it has occurred most often on undivided highways and highways where there is a hill. This has made engaging the autopilot dangerous as there are cars behind me and I could have been rear-ended on multiple occasions. Additionally, while driving manually on city streets where there are stop signs, there have been multiple instances where the vehicle has given me a forward collision warning because I am slowing down to a vehicle that is ahead of me at the stop sign. This has most often happened on uphill and downhill instances where there are stop signs.

I am reading about the Tesla braking for no reason & wanted to report my own experiences with this. I have not reported this before to anyone at Tesla, just told my husband. Numerous times (at least 5) over the past year I have owned my Y it has suddenly braked for no reason. It either always or almost always happened when I was going freeway speeds on a turn & there was a vehicle in the lane next to me that I think my Tesla thought I was going to hit. But I wasn't. It was a sudden brake that if I had not been in full control of the car with my feet ready to move so I had to hit the accelerator pedal quickly there could have been a big problem if there was a car behind me. This issue made me stop using the auto pilot on the highway it happened the most on - Hwy 80 between Sacramento & Truckee CA. But it has happened on other freeways too. It makes me very hesitant to use the autopilot unless I am on a straight freeway.

My Tesla model Y will experience phantom braking while in Auto pilot / adaptive cruise. It happens randomly but does occur every time at one point in Tacoma on I-5 head south on a bridge just before the Tacoma dome.

Traveling at highway speeds (70mph) while adaptive cruise control was active, the car applied the brakes suddenly with no apparent reason. No obstructions were present and no traffic was in the area.

While driving using cruise control or auto drive the car randomly brakes while at highway speeds. There are often no cars or objects in front of the car. I have almost been rear ended, because the car hit the brakes to almost stop. This happens every time the vehicle is placed in regular cruise control or auto drive.

Driving on 2 lane highway at about 70mph with auto pilot enabled in left lane. There was a large truck on the right. No vehicles in front of the car. The truck on the right remained in its lane. The Tesla suddenly applied the brakes, dropping the speed to about 50 mph very quickly and unexpectedly. I disabled autopilot and pressed the accelerator to get back to the original speed. It almost seems like the auto pilot decided that the truck was in front of the Tesla when it was actually in a different lane. No accident or problems except for the shock of the car breaking suddenly.

Phantom braking on highway when using ACC and FSD. When going 80 mph car will suddenly brake for no apparent reason. This happened over 12 times in one day on a recent trip. I sent video clips to Tesla for every event. This is the second report of this defect. I have ever had and ACC act this way. I am afraid I will get rear ended.

On Sept 2 or 3, 2021, I was using cruise control on long straight highway, with no other vehicles in sight, sunny clear weather, traveling at 65-70 mph. Suddenly brakes slammed on very hard. A short time later, same conditions, brakes slammed very hard 4-5 times in a row, rapidly. It was terrifying. I stopped driving for the day and I have never dared to use cruise control again. When I returned home I took the car to the dealer and told them time and location of incident. I assumed there was something wrong that would be corrected, like a Camera not pointing correctly. The Tesla employee checked the computer record of the incident, told me there was nothing wrong and changed the subject. This was an extremely scary thing for me, severe enough that I got a sore neck, and I have no doubt if another vehicle was following I could have been rear ended. I actually was relieved to read about other Tesla owners experiencing this, and thought there would quickly be a solution. I am disappointed there has not been. I have been driving for over 50 years, have never had an accident while driving….I am very cautious! I want to emphasize again, this was not a minor incident. It was very very frightening, and very dangerous.

We are experiencing two issues with our Tesla Y, one of which I have come to learn is common. That issue is the cruise control will suddenly "disengage" forcing the brakes on, either actively or just through the regenerative components. This has happened in several conditions from high speeds on interstates (>55 MPH) and on smaller state highways (<55MPH). The primary concern is being rear ended by cars following; effectively the Tesla is "brake checking". I am not aware of Tesla pushing updates or addressing this issue in any typeof inspection. There are no warnings, and I have noticed no pattern as to why it happens (and it happens frequently). I have notified Tesla of the issue. The second issue is that the control/infotainment screen has frozen and gone blank on at least four occasions. This as well has happened in various conditions, most recently on both legs of a long roadtrip on the highway. It effectively leaves all control of the car other than steering and velocity out of our control. It is scary. There are no warnings and I am not aware of Tesla doing anything to address the issue though I am aware that it is happening to other vehicles.

Car was on autopilot full self driving. Truck hit car and vehicle was severely side scrapped. Over 35k in damages. Autopilot did not stop or drive to the side to avoid collision. Autopilot failed Videos can be provided.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 60 MPH with the adaptive cruise control activated, the vehicle experienced phantom braking. The contact stated that the speed was then reduced to approximately 35-40 MPH inadvertently, and then resumed the set speed. There were no warning lights illuminated. The contact stated that there were no other vehicles or objects nearby to cause the failure. The contact stated that the failure had been reoccurring while driving in self-driving and adaptive cruise control modes. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 10,100.

Mileage: 10,100

On multiple occasions, I have experienced the "phantom breaking" problem when using either adaptive cruise control or the limited self driving feature on my Tesla. I've experienced the problem when driving in traffic (me in another lane, passing a larger vehicle) when the breaking system will activate and all kinds of warning sounds given by the vehicle. I've also experienced the problem when driving alone on the highway (no traffic in either direction), usually in daylight conditions, when the breaking system activates and alarms go off. Additionally, I've experienced the problem when cruise control is activated and a vehicle turns in front of me (either in the same direction or sometimes when turning on a cross street), it's just strange for this to happen when the vehicle is about 1/4th of a mile (or more) in front of me and the turning action of the other vehicle will be complete without causing any concern for my vehicle. This has happened 30-50 times since I purchased the vehicle in late September 2021, so I don't have specific dates for each of these occurrences but it happens so frequently that I pretty much don't use the cruise control or self driving function anymore.

My Tesla Model Y has phantom braking issue. When on autopilot (not full self-driving) traveling io the freeway, it just suddenly slows down to 45MPH for no obvious reason. This problem happens every time on the southbound direction of Interstate 5 when the car passes under the overpass bridge at Valley View Blvd in Santa Fe Springs, CA. The slow down also happens without fail in the same general area on the northbound direction of the same freeway. This incident last happened on May 27, 2022 but has happened numerous other times. It has also happened randomly on other freeways.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 79 MPH with the cruise control activated, the vehicle experienced phantom braking. The dealer was made aware of the failure; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

There was no warning light illuminated. The contact depressed the brake pedal to disengage cruise control. The contact then depressed the accelerator pedal and was able to continue driving. The contact stated that there were no other vehicles around the vehicle at the time of the failure. The contact stated that the failure reoccurred three more times while driving. The manufacturer was notified of the failure through email. The vehicle was not diagnosed or repaired. The failure mileage was approximately 4,300.

With AP and AS activated the vehicle will have multiple episodes of phantom braking. With no vehicle in front, next to, or behind for 100’s of feet or even visible to the naked eye on a divided highway. No flashing lights, no moon visible, no signs just a straight stretch of flat highway 70-50 hard stop before deactivated. Nothing on the driving display to indicate a need to brake.

Going on highway at 70mph at around 440pm on I76 on 5/23/22 with autopilot with no cars in front. Clear weather and suddenly car brakes on the highway to almost 30mph. Thankfully there was no car behind me. It could have been a grave mishap. Have reported about this earlier also and has happened multiple times.

On or about 4:30 pm Monday, May 16th there were two instances of unintended braking. Then at approximately 10:30am on 19 May another 6 instances of unintentional braking occurred. I believe this is a serious safety risk and Tesla should be required to correct.

Repeated random automatic braking while using cruise control at highway speeds. Near miss of rear end collision. Tesla service representative just said to live with it and be careful.

While in cruise control, our 2021 Tesla Model Y (WE DO NOT HAVE AUTO PILOT!) applied the brakes HARD dropping between 10-40 mph with no warning. Cruise control stays active. There were no cars anywhere near us, either in front or in the rear. Over thirty (30) Tesla bug reports were recorded on April 25 and April 26, 2022. While we were not SERIOUSLY hurt, had a vehicle actually been behind us, we would have ended up with a vehicle in our back seat and certainly serious injuries. This same thing happened six months ago on our last road trip. Tesla has blown us off saying that this simply cannot occur. Their response is that the computer cannot slow the car without seeing something. Therefore it must have seen something. This is circular reasoning and is meant to blow off the consumer. This is a serious safety issue. The braking on occasion has been violent. This is similar to the reports in other models. Tesla has twice now, within six months, addressed this issue simply by saying "it cannot occur." Seriously?!

When engaged, Autopilot often causes vehicle to suddenly brake for no apparent reason. Online this phenomenon is often referred to as “phantom braking”.

My 2021 Tesla Model Y, when using adaptive cruise control engages in phantom braking on a perfect clear road with no obstacles. On a recent road trip the vehicle braked suddenly at least 10 times while driving at highway speeds on both divided and single lane roads. This is cleariy unsafe especially if there is a car following. Tesla is aware of this problem and has done nothing to resolve it.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 60 MPH with the cruise control activated, the radar detected a hazard ahead on the roadway and deactivated the cruise control, causing the vehicle to experience phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.

Mileage: 3,000

Recently while pulling into my children's school, my car has started deciding that the entrance to the parking garage is a large truck stopped diagonally in front of me and slams on the brakes scaring me and causing everything in the car to go flying. Luckily no one has been behind me while this has happened. I am always entering very slowly, maybe 5 mph at the very fastest.

We were driving roughly 80 mph on an open highway. Clear skies. No cruise control/autopilot engaged. Vehicle slammed on the brakes. Threw both occupants rapidly forward in our seats. Lucky no cars behind us.

On 3/7/22- 3/15/22 I and my wife took our Tesla Model Y 2021 for an extensive trip from San Diego, CA to Sedona, AZ. Our Tesla does not equipped with Autopilot. On 3/7 while on I-8 E Arizona, our Tesla was on cruise control at HWY speed, it suddendly braked from 75 miles/hr to 60 miles/hr and slowly going back up without any appearance reasons! There was No cars near and around. Afterward, it happened several more times so we stopped using cruise control on the second day of our trips until return home due to safety concerns of getting hit from behind. I took the Tesla to Tesla service for a check of the issue about a week after return San Diego, and the Tesla technician took the car for a test drive and found nothing wrong!

During cruise control the vehicle automatically slows down periodically.

When my Tesla Y is in cruise control, there have been intermittent unexpected slow downs causing the car to abruptly slow down on the highway. On my last road trip it happened about 5 times.

I was driving on full self driving assistance on the highway on the far left lane. I wanted to change lane to exit but notice a car was in my blind spot so I tried to take over the car my tugging the wheel. The car sounded an alarm indicating I was going to crash I think into the left median, so it auto corrected to pull towards the right lane. I didn't want to hit any incoming car so I tried to tug it left. I believe I was fighting with the car to regain control of the car and ended up hitting the left median which ricochet the car all the way to the right hitting the median, where the car came to a stop.

Occasionally, while the Adaptive Cruise Control (TACC) is engaged, the vehicle will suddenly brake as if there is an obstacle immediately in front of the car, even though there is not one and the road is completely clear. Sometimes this happens randomly on a divided highway, other times it happens on a two-lane highway when a large truck is approaching in the oncoming lane. Sometimes it is a minor deceleration, other times it is aggressive braking. During one particular road trip, on an empty & divided highway, the vehicle braked unnecessarily over 20 times in a 1 hour span. This is an ongoing issue and continues to occur any time TACC is engaged and there is a clear, unobstructed road ahead of the vehicle. This prevents a safety hazard to any vehicle(s) following behind, as well as the occupants of the offending vehicle, because it could directly result in being rear-ended. When I initially reported this problem to Tesla in December of 2021, they refused to acknowledge it, much less attempt to address it. I submitted a second request for service that same month, 3 weeks later, and their response was the same. However, when I submitted a third request this month (April 2022), the dealer finally confirmed that this is indeed an issue. Yes, the vehicle has been inspected by the manufacturer. No warning of any kind accompanies the malfunction, and there are no discernable symptoms.

While driving in the adaptive cruise control the vehicle will suddenly go into a hard brake while at highway speeds. This has happened multiple times during both day and night, on roads varying from two lane highways to larger multi lane interstate freeways, and during weather conditions have always been clear. This feature has been typically only been used when traffic is light, as this problem has been documented by countless Tesla Y owners. This issue has been documented and reported to Tesla via the in vehicle reporting feature. When this happens it is a sudden and unexpected action that may cause another vehicle to rear end me, and or possibly loose control during the hard and sudden braking.

When driving the vehicle primarily on highways and with the Adaptive Cruise Control active, the car randomly reduces the cruise speed by up to 35 mph and then proceeds to slam the brakes. This happens intermittently on open road, 4 lane highways, with and without any traffic nearby. We logged the times that these occurred and took them to our local Tesla service center and they said “This is a software bug that we have to wait for Tesla to fix. There is no way to disable the adaptive nature of the cruise control either.” We informed them that this has been occurring for about 6 months now and they said “You’ll just have to wait until Tesla fixes the code. It gets better every release so eventually it won’t do this anymore”

While driving on interstate 25 the adaptive cruise control braked hard for no reason. There wasn’t any hazard and no traffic on clear days on a well marked road. It happened quite often . More than 100 occasions on a 65o mile drive.

Over the course of an eight hour drive on a single lane highway, the vehicle abruptly applied brakes without any warning at full speed multiple (at least 30 times). In some instances, there were vehicles in the opposite lane. In other instances, there were none. In all cases, there were no vehicles in front in the same lane. Weather conditions were clear and dry, with full daylight illumination. This issue is most likely related to the camera-only change made to Tesla vehicles, which are used for TACC and autopilot features.

All of these incidents occurred with adaptive cruise control engaged, and sometimes with lane keeping engaged. The vehicle frequently brakes, or slows dramatically, when on the freeway and there is no obstacle in the vicinity. Over the last three days I made the drive from Burbank to Anaheim along I-5. Always in the same area, the car would suddenly slow. In two out of the three incidents, the "max speed," which was set to 80, dropped to 45. Simultaneously, the car thought it was in a 55 mph zone (it was a 65 mph zone). In one of the three instances, the max speed was not changed, but the car still slowed dramatically. On the same commute, the car navigation always has me get off on Artesia Blvd, and then get right back on the freeway. The adaptive cruise has a configurable follow distance that the car seems to generally ignore. It's a number from 2 to 6 or so, and it's not clear what it's supposed to be (seconds or car lengths). It's rarely either, although it should represent seconds. When traffic comes to a complete stop, the car waits until it is too close to brake. When traffic begins moving, the car waits too long to start moving, and then accelerates excessively to catch up. Finally, when using the regular adpative cruise and lane keeping, I would signal lane changes and initiate the change. The car disengages steering but maintains cruise. In many cases, while still indicating the lane change, the car's lane departure warning will sound and it will attempt to correct my steering, which I have to physically override. My Nissan Leaf had adaptive cruise control, lane centering, and lane departure avoidance, and it never gave me these issues. Oh also, the Tesla frequently and erroneously warns of forward collision. It's really terrible, and it's due in no small part to the removal of the forward radar sensor.

Frequent abrupt and unsafe phantom braking while using cruise control. Mostly due to headlights from semi-trucks coming in opposite direction but occasionally from just a dark patch on the road. On a long road trip from WA to AZ, it made using the speed control feature impossible. The vehicle would lurch hard enough to physically throw you forward in your seat and rapidly slow the car (increasing potential to be rear ended). No warning messages or failure notifications. The problem was reported to Tesla (not to police, insurance, etc because no accident ensued) and the response was in a nutshell “it is working how it should “.

Driving along highway 330 in Iowa, car slowed from 70 mph to 15 for no apparent reason. No cars, animals or obstruction were around

The contact owns a 2021 Tesla Model Y. The contact stated while driving approximately 25 MPH, the vehicle independently stopped without the brake pedal being depressed. There were no warning lights illuminated. The local dealer was contacted and scheduled an appointment. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 11,500.

Mileage: 11,500

We have had issues with the “autopilot” function braking when no obstruction exists. Situations that trigger these unnecessary breaking events generally involve shadows on the roadway, visible disturbances such as reflected sunlight, or other visual circumstances that in some way impact the appearance on the roadway surface. These appearances are generally widespread on county roads and state highways, but are less frequent on the Interstate highways. Due to the severity of these breaking actions we have greatly reduced the use of the “Autopilot” feature, and now only us it sparingly on the interstate when the lighting conditions are good. Due to loss of confidence we use it very infrequently, only once every few weeks at most. These emergency breaking events are greatly unwarranted 95% of the time. In addition, we feel that the unexpected nature of these events and the severity of them have increased our risk of collision. This is due to the unexpected and unintended breaking causing an accident from a vehicle rear ending us on the highway. We have not been in a collision yet. I feel that this feature is not yet ready for release and it should be disabled or rolled back until such a time it can be trusted to not increase the risk of collision for the occupants. To answer the questions specifically: What component or system failed or malfunctioned: Autopilot / automatic emergency breaking. How was your safety or the safety of others put at risk?: Uncommanded and unwarranted emergency breaking increases risk for an accident. Has the problem been reproduced or confirmed by a dealer or independent service center?: No Has the vehicle or component been inspected by the manufacturer or others: Remote diagnostics performed by manufacture. No problem found. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?: Other then alerting to the breaking action, no warnings have been displayed.

I was stopping at the parking lot of my church St. Thomas Syro-Malabar Catholic Forane Church (508 Elizabeth Ave, Somerset, NJ 08873) to drop my daughter. I applied the break but the vehicle kept moving and hit the gas line of the church. The gasline broke and car front got damaged. There was no auto break and warning of the obstacle.

While driving on the highway from Ohio to Arizona in December and returning to Ohio in February when using the adaptive cruise control, my car would suddenly and without warning brake and felt as if it would stop if I had not pushed the accelerator. I drove a total of 10 days, and it happened on some days two or three times, once happening five times. Luckily when it happened the traffic was light, but if someone had been behind me, I'm sure there would have been a rear end collision. It caused my wife and me to lurch forward from the sudden deceleration, and our seatbelts kept us from hitting our heads. When I got home, I reported it to Tesla by phone and was told that someone would get back to me. On March 24 I received an email, stating that "this behavior is a known limitation" and "Traffic-Aware Cruise Control may react to vehicles or objects that either do not exist or are not in the lane of travel, causing Model Y to slow down unnecessarily or inappropriately." Tesla did not offer to remedy the problem, saying only that "The braking behavior will improve over time with software updates." Tesla suggested that somehow I did something wrong, when it stated: "When using Autopilot features it is the driver’s responsibility to remain aware and be ready to take corrective action at all times." There was no corrective action to take except for the sudden braking of the car.

I have experienced the now well-documented "phantom braking" problems with my 2021 Tesla model Y. This happens on long trips when I use "Traffic-Aware Cruise Control." The problem seems to occur most often at the crest of a hill, especially if there is a guard rail.

Since buying the car 6/30/21 the automatic emergency braking has activated >300 times not once was it appropriate. We have had the car back to Tesla Service twice to repair the problem with out any improvement. It is only by luck that we have not had an accident. This is not an effective safety feature and it is increasing the likelihood of an accident. If Tesla cannot fix this it should be forced to deactivating the system

For the last few software updates and for a few months the vehicle will phantom brake and apply aggressive stopping in traffic for no reason when using cruise control, autopilot, or full self driving. Instances have occurred which has nearly caused us to be rear-ended by other vehicles. Additionally the car will turn aggressive when using passing lanes. We have experienced instances where the car will turn into a short right turn lane at highway speeds unexpectedly and then require immediate intervention or the brakes will be applied very hard. These situations are repeatable and occur frequently for no reason.

We've owned this car since delivered in June 2021. Took a trip from AZ to MO in July 2021. When using cruise control, the system occasionally and severely activated the brakes when passing a large vehicle on a four lane divided highway and in some cases no one else was around on the 4 lane divided highway. Auto braking only happened if on cruise control and did not occur if cruise not activated. I mentioned this to a service tech at one of the charging stations in Rolla, MO who indicated it was a known issue and they were working on it. I didn't report it to Tesla thinking it was being handled, but now I see many others reporting it and you dates indicate cars produced prior to April 2021. I'm assuming ours was produced around that time.

I was driving northbound on Highway 1 on 3-18-22 from Ventura California to Clayton California where I live. Four times through my trip the car suddenly decelerated and the brakes were applied automatically for no reason whatsoever there was no traffic in front of me there were no obstacles in front of me there were no hazards in front of me, it was open road and for whatever reason the car auto braked which immediately reduced my speed to a dangerous condition. If I had been in traffic I would’ve been rear ended!

Vehicle brakes randomly at highway speeds while utilizing ADAS. Brakes hard and fast without warning.

Using autopilot on 405 freeway at approximately 60mph. When approaching stopped traffic, I initiated a lane change using the turn signal. Halfway through the lane change the car swerved back into the original lane and slammed on the brakes causing the car behind me to rear end the vehicle. Damage was minor. I reported the incident to tesla on October 17. The original response was to schedule a service appointment. The appointment was later cancelled after I received a message from Tesla legal regarding autopilot. My message to Tesla was deleted from my service history. Tesla autopilot, TACC and FSD are not safe to use on any roads. I have experienced dozens of phantom braking episodes in this car on all types of roads in clear conditions.

The cruise control of Tesla is majorly defective after taking out the Ladar component as it is entirely dependent on cameras. Sudden or phantom braking has been so bad that sometimes I avoid using it. My most recent episode happened last weekend as I was driving at a two way country highway at 50mph to get to the interstate. I was headed south between 9 to 10am. The sun was on my left (east) and there was a truck approaching on the opposite lane. When the truck passed (I guess it cast a huge shadow as it blocked the sun on my left) the car slammed on the brakes. There was no warning. Luckily there were no cars behind immediately behind me, otherwise we would have been rear ended in a possibly fatal accident.

While using adaptive cruise control on my Tesla Model Y on a 1974 mile trip to Florida and back the car would emergency brake for no reason. This happened at least 25 times on the trip. I believe this is being referred to "Phantom Breaking". So far I have been lucky and no one has rear ended me but that is a strong possibility.

Pulling into a parking space, at very slow speed, pressed service brake to stop car. The car suddenly accelerated at high speed, hit a tree directly in front of the space, veered off and sprinted across another parking space and a two lane passage, hit a brick pillar, veered into the wall of a restaurant, bounced off the wall and back into the street. All airbags deployed. No one was injured. Car probably totaled.

Phantom breaking while using adaptive cruise control. Happened 3 times in past two months. First two times were traveling on a major highway, both on a hilly section at the bottom of a hill, with no other cars nearby. The car apparently thought the hill was something that should cause the breaks to engage. Car went from about 70 to 55 in a few seconds. Very startling. The third time was on a residential road, going about 38-40. There were no cars nearby, and the breaks engaged abruptly. The safety implications are obvious, although luckily there were no cars behind us when the breaks went on. We reported these incidents to Tesla today and asked for a service appointment. A Tesla representative called us and said we had assumed these risks when we bought a Tesla, there was nothing they could do, and it was probably driver error. They did agree to make an “internal report.” We told them we would report this to you. This is our second Tesla. We had a 2018 Model 3 and never had any problem like this. We wanted more storage space and higher seating, so we sold the 3 and bought the Y in July 2021, not understanding that Tesla had changed to an “all camera,” no radar/lidar safety system. Add us to the growing list of evidence that the new system is dangerously faulty.

Have had problems with 'phantom breaking" while using adaptive cruise control (not full Autopilot). This has happened over a dozen times over the last several firmware updates including latest version 22.4.5.16. For no obvious reason, the car just applied the brakes fairly hard (no skids) while at highway speeds without other vehicles nearby or no shadows visible.

We were driving on I-8 yesterday from California to Arizona and while using cruise control the car kept phantom braking. It happened multiple times - some times the braking was so hard, it threw us and our children forward in their car seats. It was terrifying and almost caused us to get into multiple accidents. There was absolutely no reason for the car to be braking . We tried to notice a pattern. It almost seemed like the car was afraid of its own shadow in front of us (the setting sun was directly behind us at points). But the phantom braking also happened when there was no shadow and nothing at all around. Absolutely terrifying.

Without warning and with the lowest setting for front impact prevention my cruise control randomly slams on the brakes. This happens basically anytime I use the cruise control, so I just don’t anymore to prevent possible collision. It happens when no cars are around, when cars are in the oncoming lane but not crossing the line. It happens in any situation and it is very frustrating. I put in a service ticket with Tesla, to my understanding there is not currently a fix.

While using the ADAS the Tesla had several incidents of phantom braking. We would be going 80 and it would slam the brakes on and take us to 50. It did it several times on a drive from Dixon,CA to Flagstaff, AZ. There were no cars near or anything remotely concerning on the road at the time the incidents took place. We called Tesla and reported and they could find no codes or system issues.

Since receiving Tesla Model Y 2021.44.x software update, I've experienced phantom braking on the highway at least once every time I drive it using autopilot. This continues through the software currently installed 2022.4.x. The most common scenario is I'm in the second lane from the right, a car is entering the highway to enter the first lane from the right. Each car is in its own lane. My car sometimes brakes for no reason. On many occasions there are no cars anywhere near me, but the car breaks suddenly. Not a danger for others, but dangerous for the driver and upsetting for passengers. I now only engage autopilot when there are no cars close behind me and no one else is riding with me. I don't want to cause and be responsible for someone hitting me because my car braked for no good reason. I'd prefer regular old cruise control to this behavior.

Hello, We have had our car for almost a year now. Ever since we purchased the car we have been having an issue with the "Phantom Braking". On writing about it to Tesla within a few months after the car purchase, they sent a representative to our house with whom we went for a test drive. On the test drive, while on the highway with the vehicle on Auto-Pilot the car suddenly slowed down fast, similar to "slamming the brake", for no reason. There was absolutely no obstruction in front of us. The representative mentioned that he had heard of this phantom braking but this was the first time he really saw it and he would pass the info to Tesla. We later got a reply from the company which explained that "as more info is gathered by Tesla from your experience as wells from other owners, the system will improve and issues such as yours should decrease." We still consistently get this problem on ALMOST every trip on the highway and if the auto-pilot is engaged. In fact it does happen multiple times on each trip! We sincerely feel that it is very unsafe esp. for a software which is supposed to make driving safer. Kind regards, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Using the Autopilot feature, I experienced the unexpected and phantom breaking several times while driving at highway speeds of usually 70 MPH or greater. This occurred well over 5 times in a single 300 mile trip and each time I disengaged the autopilot to recover from the sudden breaking.

We have noticed an increase in phantom Braking while using cruise control and/or auto pilot. Prior to November it would happen randomly and only on single lane highways. Now it happens every time we try to use cruise control. It is very dangerous as we may be rear ended it stops so fast with nothing in front of us. We have reached out to Tesla more than one time and they just suggest we disengage use if cruise control if we experience this random phantom braking. We have reported this is not rare or random it’s constant and every time we attempt to use this product we paid $10,000.00 for. We are not safe with this braking and Tesla basically says they are working on it.

Phantom breaking at high speeds for no reason

While driving from Tucson to Denver the vehicle suddenly decelerated and/or braked no less than hundreds of times with varying rates--sometimes just a couple miles per hour and other times more than 30 miles per hour. These events were generally on a divided interstate highway with clear visibility, flat, straight roads without precipitation and oftentimes without another vehicle within 1/2 mile or more. These events even happened 3 times within 3-4 minutes while I was speaking to Tesla roadside service trying to disable all sensors/interventions. More than once there was a vehicle behind me at highway speeds that thought I was "brake-checking" them and would anger them and cause them to honk and give me a few finger symbols (road rage)... there was no reason for the car to suddenly brake; no cars merging or in front of me other than light vehicle traffic in the opposite direction of the DIVIDED interstate. I asked several times if there is a way to turn off all the "assistance" (unsafe interference) and just have it function as a normal cruise control without "traffic aware" and other automatic braking features--but the answer was no. I am not exaggerating when I say this happened hundreds of time during my trips. I always turned off the speed control when the roads were curving because I knew that it would suddenly brake during a mountain pass curve and upset the vehicle--make it difficult to control, and potentially cause an accident at high speed for NO reason. My risk tolerance is fairly high, I have been driving cars with "Eyesight" and radar speed control and advanced safety features for over 10 years and have never felt less trusting or less safe than I do now in my Tesla Model Y. I think Tesla should disable the "safety" feature until they can resolve the issue--I believe it will cause accidents even when someone is fully aware of its sudden, random braking issues. I have many video clips/pics of when the events occurre as Tesla asked me to record.

While traveling on US 93 southbound, the vehicle raandomly saw oncoming traffic as a threat and applied braking. This was most pronounced seemingly with large trucks, usually white in color, and occasionally apparently with flashing lighted signs. This phonenomen has occured at other times. Often in city traffic on city streets, it is overly sensitive and applies braking when cross-traffic occurs but is not yet a threat. I have not yet been rear-ended but have decided to only use this feature when I can be reasonably sure no one will be close behind me. Tesla's response is that this is a Beta feature. Your safety rating included this "feature" as one of the positive factors. Maybe that was a mistake?

While driving 50-55 mph down a two lane highway, with adaptive cruise control in place, the vehicle suddenly slowed and signaled a front collision by beeping. It was terrifying as there was nothing in front of us. It was a clear day and we were lucky that there was no car behind us, as it could have easily caused an accident. We are now not wanting to use our cruise control or the autopilot that we purchased for this vehicle, until more is understood about the cause.

This complaint is specific to the automatic control of the Model Y related to "PHANTOM BRAKING". This is an ongoing problem with the "AUTOPILOT" and "FULL SELF DRIVING" functions on my car, it has always had. Most of the miles on my car are freeway and highway miles. Regardless of which of the automatic functions selected on my car, "phantom braking" occurs repeatedly in a startling fashion that doesn't seem to be related to the environment the car is being driven in. The problem is consistent enough that I will not use any of the auto driving functions when I have passengers in the car with me. The problem requires constant intervention by the driver. There are 2 versions of this type of un-commanded breaking: 1. Unexpected braking with no computer warnings or alerts. It can be hard braking or, light to medium breaking, for no apparent or justifiable reason. This type of breaking can happen sporadically or, at times it can happen in a chain fashion that can be so continuous that it becomes necessary to disengage the automatic functions completely. Although, it happens at varying times of day and different kinds of traffic, making it nearly impossible to relate the event to any specific cause, I have noticed it happens almost 100% of the time when a large vehicle is approaching from the opposite direction on a two lane road. That will usually be version 2 type of full emergency braking. 2. Full emergency braking with computer visual warning and loud computer audio alert. This type of braking is EXTREMELY dangerous because, just like with version 1 braking, it happens un-expectantly and for no apparent or justifiable reason. If this type of braking happens in freeway traffic, as I have experienced, it can cause a rear end collision or worse, a chain of collisions. Tesla is aware of this problem and I have reported it multiple times. I have received no response from Tesla related to these problems. I have experienced this problem since the car was new.

the emergency braking failed, by activating when it should not have activated. Caused hard braking which the rear car almost ran into me. Vehicle has not been taken into dealer to be reproduced or confirmed by dealer. Vehicle has not be taken into dealer to be inspected. On vehicle display, there was a pedestrian image causing hard braking, but no actual pedestrian was there.

While using Autopilot, the vehicle brakes when coming over the crest of any hill on the highway. It's not even occasionally, it's every single time I have Autopilot/CruiseControl enabled, it phantom brakes. To be clear, this is with just Autopilot, not FSD. My guess is the car can not see the road on the other side of the hill, so it freaks out. Also, this is a case of the car braking, it does not disengage Autopilot. After this happened about 20 times on a road trip I have just stopped using it. It's terrible. Also, another detail is this happens whether it's just on cruise control or autopilot. Even if I am in full control of the steering of the vehicle it still happens. Tesla doesn't have an option to just maintain speed with the cruise control where I control braking, it's the adaptive cruise control or Autopilot. Very frustrating to not be able to use something as basic as cruise control when driving across the vast expanse of West Texas without having my kids jostled awake at the crest of every hill (big or small).

This report is not about a single incident, but rather a REPEATED problem over several years with the adaptive cruise control on 3 different Tesla cars I have owned. These cars are a 2017 Tesla S, and 2 different 2021 Tesla Y models. in each case, whenever these cars are driven on a highway with the adaptive cruise control engaged, several times during each hour of driving, the cars will rapidly brake/decelerate with no action taken to cause the situation by the driver, nor any external situations with the traffic that would justify them. With the Tesla regenerative braking, these deceleration events are so extreme that it would be easy to imagine an accident with a car following closely behind. Indeed, with these situations occurring with no warning and extreme braking they are quite frightening to the passengers traveling in the car. During the most recent occurrence, I noted the exact day and minute of it's occurrence, and filed a service request with the local Tesla office. Even with the exact time of this event, the service center was unable to find anything wrong with the car. The Tesla service center attributed this issue to problems with the Autopilot and Full Self Driving software, but none of my cars have had this optional software-only the software which came standard on each of these cars. While otherwise appreciating the good characteristics of these cars, this unexplainable deceleration problem is what caused me to sell the prior 2 models before purchasing this latest model Y, hoping that this problem would not recur. It is worth noting that I have owned several other make and model cars with comparable adaptive cruise control, yet this situation never occurred even once on any of these other makes of car.

Multiple hard phantom braking events using adaptive cruise control on interstate with no obstacles.

Multiple hard phantom braking events using adaptive cruise control on interstate with no obstacles.

On Friday February 25, 2021, while driving on Florida’s Tamiami Trail (41), my Tesla repeatedly experienced extreme phantom braking, even though there were no vehicles in front of us or behind us either in our lane or the oncoming lane. It was a sunny bright morning between 9:30 and 10:00 AM.

When driving cross country from Illinois to Texas, the adaptive cruise control did the phantom braking 3 separate times. The first time scared me and I was not prepared for the car to act that way. Well, wasn’t prepared for the others either. I was going 75 and to have the phantom braking kick in is a safety hazard. The car behind hit the horn.

Car will suddenly brake hard when a pickup truck or semi truck is in the oncoming lane at highway speeds when adaptive cruise is engaged. This happens nearly every time a larger vehicle is in the oncoming lane, mostly only on two lane highways. Will also [XXX] occasionally brake for apparently no reason with adaptive cruise on. Tesla service knows of this problem and claims there is no fix. The hard braking happens every drive multiple times and nearly causes us to get rear ended by following cars. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at various highway speeds with either the cruise control or self-driving feature activated, the vehicle would independently brake without warning. The contact spoke with the service center about the failure and was informed that they were aware of the failure. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was unknown.

Sudden and dramatic application of emergency collision braking for no apparent reason. No objects in the road in the driving path of the vehicle, but the emergency braking system engages. Available for inspection upon request. Having this occur during traffic can result in being rear ended as the braking can be so severely applied. Bodily injury in the form of whiplash is also foreseeable. The problem has not been reproduced by the dealer or service center. The vehicle has not been inspected for these problems. There is a warning chime prior to almost every event. Sometimes it just slows without warning. They first occurred on our first long road trip beyond twenty miles.

This vehicle when on ADAS (aka autopilot) and adaptive cruise control I experience constant "phantom" braking where car will slow down or slam on brakes for seemingly no reason. Most noticeable on a non separated highway phantom braking occurs constantly and is very predictable when large truck is near on the oncoming lane; happens probably 80% of the time. Slamming on the brakes for no reason is alarming and dangerous in my estimation. This system is completely unusable and very unnerving. Ironically I had a 2019 Model 3 with the same features and did this very rarely so this feature is much worse than it was on older vehicles with radar.

Phantom braking on a two lane highway. The vehicle would suddenly go into emergency braking when a truck was coming in the opposite direction. We were making a 200 mile round trip and it happened approximately 6 times. Called Tesla who advised to disable automatic braking on two lane highway until bug was fixed,

I was on a road trip and no less than 20 times over 10 hours, my car when standard cruise control was set, the car applied the brakes HARD for me without any warning. It went from scary to nearly resulting in a rear-end collision. The cause ranged from absolutely no reason except for maybe a slight dip in the highway(? weird) to oncoming traffic - standard, nothing close to an emergency situation. I had ALL auto features disabled and was just using the set speed feature. I've submitted a service request but the next appointment is in two weeks and in the meantime, I'm frankly scared to drive the car. It happened at 70 miles per hour and immediately dropped me down to 40 on the highway and I just about had to take a break from driving I was so shaken. It also happens on local backroads when I have the feature set to just 35 miles per hour.

This is the second Tesla I have owned and the previous model did not have this problem at all. This vehicle has phantom emergency braking occurrences during use with the cruise control and also with the auto drive feature. It will randomly brake hard when there is nothing around the vehicle, either in front, back or sides. I have contacted Tesla 3 times, the first two they said nothing was wrong and the 3rd time is scheduled for February 28 here in Houston. The first two times Tesla told me to record the time and place of the occurrence so that they could look at the data that was being input to the vehicle. I did this but it did not work. When the vehicle has an emergency braking occurrence all of the occupants of the vehicle are violently slammed forward until the driver can push down on the accelerator or disable the cruise or auto drive. This has caused us to almost lose control multiple times. As of right now no one can use the cruise or the auto drive feature at all, it is just too scary when the vehicle decides to have a phantom brake event with no problems around the vehicle. THIS HAS OCCURED DOZENS OF TIMES OVER THE LAST FEW MONTHS.

This has caused us to almost lose control multiple times. As of right now no one can use the cruise or the auto drive feature at all, it is just too scary when the vehicle decides to have a phantom brake event with no problems around the vehicle. THIS HAS OCCURED DOZENS OF TIMES OVER THE LAST FEW MONTHS.

Daily phantom breaking, puts me at risk of being rear-ended. There is one specific stretch of road where this always happens - wide 4 lane road free of any possible complications for the vision system. Happens regularly and without warning in other circumstances as well.

I was driving on a 2 lane highway at about 60 mph in the middle of my lane. The adaptive cruise control was used to manage my speed. Another vehicle was travelling in the opposite direction going toward me, and in the middle of their lane. The other vehicle was an 18 wheel truck. Suddenly, with no warning, the braking system slowed my vehicle. Both myself and my wife felt our seat belts tighten quickly. There was a vehicle behind us, that nearly hit us when the brakes were applied so quickly, for no apparent reason. I had to quickly put my foot on the accelerator pedal to stop the braking, and get back to the correct speed. This has happened several times, usually when driving on a road that gently curves to the right. The sudden braking also occurred when there was no other traffic, just a new section of pavement on the road ahead of us. The loud collision warning sounds came on each time, which startled us. There was no reason for the warning. This caused me to react very quickly, which could have resulted in overcorrection, possibly leading to an accident. After learning about bug reports, I sent in a bug report to Tesla immediately after every incidents I called Tesla to report the problem. They eventually replied that there were no issues with my vehicle, that it was working properly. I set up a service appointment to have the problem diagnosed. I wanted them to diagnose the "phantom breaking". Their diagnosis - "Verified Proper Operation". They noted that it was a "Known Characteristic, future firmware solution". The correction was "Remote education" - they tried to inform me how to correctly drive with adaptive cruise control, then told us to stop using cruise control. My wife and I are scared of using cruise control, as we are sure it will happen again, and someone could crash into us from the rear if it happens again. The way Tesla responded made us feel as if they didn't care about our concerns.

Autopilot or Cruise Control Performance - Several times over the last couple weeks, when I disengage TACC/AP by pushing the stalk up during driving, the car shifts into Neutral instead of staying in Drive and engaging the regenerative braking. I cannot reproduce it on demand, it is intermittent. This causes a collision hazard as o am expecting braking to occur but it does not.

Vehicle engaged full automatic braking inappropriately while driving around 55 miles per hour on a two-lane Oregon highway. No traffic in front of me or any debris in road.

Frequent phantom braking events occur without warning in cruise control and range from light braking to very hard braking. This especially occurs on two lane roads and occasionally on four lane roads and rarely on freeways, but it does occur. For example, we recorded approximately 14 phantom braking events within 20 minutes on US 191 North in Utah (2/12/22), and 28 phantom braking events on US 6 in Utah (2:46 pm to 4:37 pm on 2/17/22). The "hard" braking occurs without warning and rapidly reduces speed by about 20 mph, which is extremely dangerous especially with traffic from behind when traveling the posted speed limit of 65 mph. The majority of observed phantom braking events will reduce speed from 5 to 20 mph. Phantom braking has occurred the entire time we have owned the vehicle (8/21)

I was driving south on Highway 101 on 2/8/22. I was using the self driving feature. The car abruptly slowed down and was appearing to stop even though there was no collision imminent. Traffic was moderate.

Sometimes randomly but often in the spot, when in autopilot, the car will randomly brake hard when there is no car or obsticle in front of me. This has occured when I'm on the highway and I've noticed a pattern that it happens when I go under and overpass. Its usually very sunny and there is a strong shadow in front of the car. I think with the camera vision autopilot it thinks the shadow is an obstacle in the road but I'm not sure. This happens very suddenly and luckily has not happened when a car is following close behind me. But if it did this could definitely cause a rear collision at high speeds.

When using cruise control, the vehicle unexpectedly brakes on multiple occasions. This occurs when there are no other vehicles in the vicinity. It has also occurred when passing tractor trailers. I understand there have been hundreds of similar reports. No warning provided prior to the failure. This is a safety hazard that must be addressed. Tesla service will be notified.

44E east of Joplin car braked hard while on autopilot. Pressing the accelerator would override but as soon as you let up it would hard brake again even though the car was below the cruise control speed

At 12:21pm on February 20, 2022, while driving on a divided highway (US-36), the Tesla Model Y braked hard with no cars nearby. The braking occurred as the car encountered a shadow on the roadway from an overpass. The sun was very bright, so the shadow had very high contrast. We suspect this is a case of "phantom braking", as has been reported with many Tesla Model Y and 3. The problem is not easily re-producible, but we also do not feel safe using the cruise control feature any longer, so it's unlikely to be reproduced soon. The vehicle has not been inspected by Tesla, nor confirmed by the dealer. There were no warning lamps or chimes - just a sudden, hard braking for approximately 1 second, losing approximately 20mph, immediately.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at various speeds with the cruise control activated, the braking system erroneously activated, causing the vehicle to abruptly slow down and reduce speed. The contact indicated that the failure had occurred on multiple occasions. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 500.

Mileage: 500

While adaptive cruise control is enabled, the car will hard brake at random. The screen doesn't indicate why the car is randomly braking, not are there any other indicators as why or when this will happen. This occurs most often while going around corners, up hills, or when traffic is oncoming in the other lane. This happens on standard roads and highways - although highways are a little better as long as the opposite bound lane is separated by a wide median. Contacted Tesla support December 16, 2021 in which their reply was that "the car is learning... apply constant pressure to pedal in order to override braking system". I did try that for a couple of months, and instead of hard braking, it is a little gentler, but then I run the risk of going over the speed limit as constant pressure has to be applied ontop of whatever the cruise control is set to. Not too mention this defeats the purpose of having cruise control.

Phantom braking when adaptive cruise control engaged. More extreme braking occurs when oncoming traffic approaches from uphill or oncoming vehicle is large (e.g. box truck or semi tractor). Also occurs when large objects appear well off the right side of the road.

WHILE DRIVING IN AUTO PILOT ON HIGHWAYS, NOT FREEWAYS, THE CAR WILL SUDDENLY BRAKE WHEN IT SEES A CAR ON THE SIDE ROAD THAT IS NOT COMING INTO TRAFFIC. THE BRAKING IS VERY SUDDEN AND HARSH. THROWING DRIVER AND PASSENGERS FORWARD. I WILL NOT USE THIS FEATURE BECAUSE I FEEL IT IS UNSAFE TO USE. PLEASE MAKE TESLA MAKE CHANGES.

Multiple occurrences of unanticipated hard breaking. Adaptive Cruise Control will slam on the breaks when car is adjacent a pedestrian or bicyclist. The car car doesn't slow down as it approaches a pedestrian walking on the side of the road but slams the breaks on when the car is next to the pedestrian or cyclist. This unanticipated event causes the car to immediately drop in speed between 5 to 30 mph. Any motorists following will not be prepared for this illogical behavior and significantly increases the probability of a rear end collision. This behavior of the Adaptive Cruise Control has also occurred when the car approaches oncoming highway traffic regardless of whether the highway is divided or not. In this event, if the driver of the Tesla model Y does not instantly take over complete control of the vehicle a severe rear end collision can occur. I have not addressed this with Tesla nor have I taken my car in for inspection. I have been told by an owner of a Model 3 and an owner of a Model S that they have also experienced similar situations caused by the poorly calibrated performance of the Tesla Adaptive Cruise Control system. I have been forced to stop using the Adaptive Cruise Control and Auto-steer on my Model Y as this problem is on going.

The adaptive cruise control feature frequently hits the brakes despite no obstacles in the road. Major triggers seem to be: Oncoming cars on an undivided highway at night. Oncoming 18-wheelers on an undivided highway at any time in day. Going over the top of a hill. Small bumps in the road at night. A large vehicle with blinking red hazard lights in view. (This will slam on the brakes and set the speed limit to 50 as it seems to think it's an emergency vehicle) Blinking red traffic lights. Sometimes HOV lane entrances will use a blinking red light to show that the lane is closed, and the car will slam on the brakes thinking it's an emergency vehicle. There's a risk of rear-end collisions caused by the sudden decelerations. Most of these events happened on highways with low traffic. No warning lights or messages were displayed before the events.

The car ‘phantom’ brakes all the time. It is so bad that I cannot use the cruise control. I’ve had several instances where vehicles following me almost hit the back of my car because my car braked so hard.

While I’m adaptive cruise control or Autopilot the vehicle has phantom braking which occurs. Vehicle will slam on the brakes for no apparent reason.

Phantom braking. I have had numerous incidents of phantom braking, and can reproduce the problem at will on a particular stretch of road. It happens regularly on city streets, occasionally on Interstate highways. It is sufficiently unreliable as to be worthless. I reported the problem to Tesla online in a service request, and was told that the problem will be or has been solved with software.

While using the adaptive cruise control on the highway, the car abruptly slowed down from approximately 70 mph to less than 55 within a few seconds before I was able to push the gas petal and reaccelerate. This has happened 3 other times in the last several weeks and I am now afraid to use the cruise control. Whereas no accident occurred, if it happened when another car was following me closely, it could have easily resulted in a crash. Each time this has happened, there were no other cars nearby so I don’t know what the car ‘saw’ and was reacting to. The date entered below for the incident is the most recent occurrence.

My Tesla Model Y has terrible Phantom Braking problems. The AutoPilot features on the Tesla is extremely dangerous. Phantom Braking can happened anytime whenever AutoPilot feature is used, it just suddenly slow the vehicle without warning, there’s no other vehicle in front of me. The problem occurred more on a less busy freeway/ highway, sometimes it’s totally useless because the the feature is too dangerous. On a two lane highway, when more car detect a larger vehicle on the opposite lane, it started slowing down, sometimes that’s very dangerous because cars behind me almost hit my car. Tesla’s AutoPilot is extremely dangerous, they should recall the car and fix the problem.

When using autosteer or adaptive cruise on I5, our car performed a phantom brake that cause the truck behind us to nearly flip over in order to miss hitting us. We were not in the lane by the divider, there were wide open lanes in front of us to the left and right by half a football field and no overpasses at the time. We slowed from 69 to about 39 before I could correct the braking. This happens so often we do not feel safe using the cruise control at all.

Wipers have frozen down in place. Car is garaged and the buildup was from the road and not parked accumulation. New car <7k miles. Phantom breaking on the autopilot system where it will slam on the breaks always at some points on a commute and when driving in some conditions such as oncoming opposite side of road traffic at night with headlights on. The car will momentarily and to an extreme degree sometimes slam on the breaks.

The car randomly brakes hard when the cruise control is on. It’s intolerable on roads with a lot of tree shadows or even clouds.

These issues occur w/ no warning, occur randomly, in all conditions. Issue 1. Vehicle randomly slams on the brakes with no obstructions or vehicles in front. This occurs at highway speeds as well as neighborhood speeds. I'm worried about being rear-ended. This occurs daily. Issue 2. Vehicle thinks oncoming traffic is in same lane and attempts to emergency stop. Issue 3. Upon changing lanes, using auto lane change, vehicle serves back I to lane for no reason.

Phantom braking has occurred multiple times randomly when autopilot and cruise control are activated.

On multiple occasions the car triggers emergency braking when no obstacle is in front of the car, often at high speeds. The car is not equipped with radar, and relies entirely on camera-based adaptive cruise control. this is a safety risk and possible rear end collision cause. Due to the lack of radar, the vehicle also accelerates to desired speed slowly when using adaptive cruise control while on interstate. Often times resulting in traveling under the speed limit for an extended amount of time, causing a safety hazard.

While using adaptive cruise control on I-25 making round trips between Albuquerque and Ft Collins, I have experienced numerous (dozens) phantom braking events. They are so frequent that I have stopped using adaptive cruise control. Almost all of these events occur when there is no traffic and no discernible reason for braking. In many cases, my first response is to look in the rearview mirror since I'm worried that if someone is behind me it would cause an accident since the stop is very unexpected. To date, there has not been a close call. The stopping varies between slight hesitations causing 1-2 MPH decrease to dramatic decreases of over 20 MPH. I have made numerous 'bug reports' using my voice in the car immediately after many of the events. I also scheduled a service call but was told that they examined the software and could find no problem. There is no warning of an impending braking event.

We have had multiple incidents from July through Dec 2021when the vehicle is operating in cruise control and brakes hard for no good reason. Most of these are on highway 86 between Tucson and Sells. For some of those incidents there was an oncoming school bus, which may have been the visual trigger. For others we do not know the cause.

Car slams on brakes at inappropriate times. Ex: 1. When a car makes a left turn across my travel lane several blocks away. 2. When a vehicle moves into my travel lane, going the same direction, several blocks in front of me. 3. For no reason I can discern. Cars behind me often honk. Could easily rear end me. Thankfully hasn't happened. You are welcome to inspect it. Don't think service center has tried to replicate the braking. No accident so not reports. Just very scary, thankfully. No warning lamps, etc. Anticipating question about dates, happens randomly, but pretty frequently. At least weekly. Speed also variable. Sometimes 35, sometimes 70, and in-between

Multiple phantom braking incidents using cruise control on 2 lane roads when there is no hazard

Car braked for now reason when the entire roads in front was clear and there was a car behind me. It was a hard brake which scared me and my family. That was very very close to being in an accident. Need compensation from Tesla for going through such an incident after paying so much money for the car.

On a cross-country trip from Washington, DC to Oklahoma City on Feb 5th and 6th (Saturday and Sunday) I tried to use the "adaptive cruise control" for the first time. Terrifying. The car would be driving along at 80mph, and then it would suddenly slam on the brakes, seemingly without provocation... with a 30-35mph sudden deceleration (absolutely nobody/nothing in either of the lanes in front of me). This was not while using the "full self-driving" feature, as I did not pay the extra $10k for this functionality, only the adaptive cruise control. Another very disturbing thing was that when the adaptive cruise control was enabled, it would not allow me to turn off the windshield wipers... and every so often the wipers would just start frantically wiping despite only a small bit of rain hitting the windshield (again, disturbing, as it is very startling when it happens out of nowhere). Needless to say, after this happened 5 or 6 different times over these two days, I turned off adaptive cruise control and kept it off. Tried to contact Tesla service, but they kept dodging the issue so I stopped trying.

Phantom braking. Vehicle slams the brakes on as soon as it sees an approaching vehicle in the opposite lane. Cruise control is unusable on two lane roads.

When driving with the cruise control on, the car suddenly and rapidly brakes for no apparent reason. Nothing in front of the car. Problem has happened multiple times. Very hard Braking that if someone was behind us it would likely have caused an accident. We no longer use the cruise control because we are afraid of it causing an accident.

Multiple Emergency braking events basically everytime a semi passed during auto pilot and some phantom braking when only using traffic aware cruise control... Lucky to not get rear ended

This issue has happened numerous times since I’ve taken possession of the car. The vehicle perceives a potential collision when no such potential collision exists. The car will suddenly brake while traveling down the interstate at high speeds (maximum speed limit). Fortunately, no one has been so close behind me that this has resulted in an accident, but it is only a matter of time. I took it in to a Tesla dealership this week to have it looked at. Despite the adjustments made at the dealership, it happened again on my drive home from the dealership. I feel this automatic breaking system is unsafe. It also breaks suddenly at sharp turns or curves in the road, even at low speeds. It doesn’t anticipate the turn and thinks the driver is heading straight into an obstruction. Part of the issue is learning to think like a computer and learning to anticipate what the computer thinks is happening as opposed to what the human driver thinks is happening. It requires constant vigilance.

I have had over 18 occurrences of phantom braking while on cruise control; rapid deceleration without warning. I reacted by accelerating with the brake pedal. I reported this twice to the service adviser. One response was I needed to return with a date and time when it occurs again. When I did this, they could not find it in the computer record. They explained this occurs because cruise control is part of the self drive software and that is only in beta stage.

The Tesla Model Y had a software update at 12:05 am on Feb 13, 2022, which was complete. I drove the car to local YMCA at around 8:15 am on Sunday Feb 13, 2022, for my swim exercise and drove it home at around 9:30 am. I planned to park it by backing up to my driveway so that I can charge it. I positioned my car, with the front facing my neighbor's house. My foot was on brake and my right hand was moving the Drive Stalk towards R for reverse. The car all of the sudden flew forward on its own! It was only stopped after it hit my neighbor's house, making a big hole into her house, and causing severe damages to it outside and inside (smashed furniture and falling glassware), as well as to her landscaping. When this happened, my foot was still on the brake but pushing brake did stop the car. Additionally, hitting a tree also did not stop the car. Only the house and its strong frame stopped the car. The front of the car was totally damaged, including pieces falling out of the car and a big piece under the car falling down. Please come by immediately to take photos and examine damage. I called 911 immediately. The police and emergency trucks came. Since no one seemed to be visibly hurt (I had a whiplash and headache due to impact but was more was scared and shocked), the emergency medical crew left. The police said they are not making a report because the accident happened in private driveway and no crime was involved. I called Liberty Mutual to file a claim and was directed to file it online. I never bought the Tesla autopilot package but the new software update showed autopilot is an included package. This is a problem. I called Tesla customer service and reported this serious software malfunction. Thinking back, software problem caused another safety concern that started on Feb 6, 2022. Not only the right passenger door cannot be opened from outside, it also cannot be opened from inside. Someone could be trapped inside. This is a SAFETY alert!

At 55 MPH on clear day, with visible lines the car automatically braked when an on coming truck passed nearby causing near rear end collision. I have two good videos of this if you wish to see actual conditions. Dealer acknowledged problem but said there was no fix and I should turn off automatic braking.

While driving my Tesla Model Y with Cruise Control activated, the vehicle would inexplicably brake/decelerate rapidly without any vehicle traffic in front of the car. It would occur at its worst while changing lanes, as I approached another vehicle from behind and attempted to change lanes to overtake. I would either be mostly in the other lane, or had already successfully changed lanes, when the vehicle inexplicably braked/decelerated. It was alarming, frustrating, and infuriating as it seemed clearly unjustified. This occurred while on the interstate, which was extremely dangerous given the speed traveling at as well as the number of vehicles that typically travel on the interstate. I have not used the feature since, and have even attempted to try and disable the feature while still being able to utilize some sort of basic cruise control feature, to no avail.

I have owned two Tesla Model Y's, this one from 2021 and a 2022 version as well. Both vehicles have exhibited the type of "phantom braking" that I have now seen described by several other owners. When attempting to use either the full Autopilot system (which includes both adaptive cruise control and lane keeping assist), or when using just the adaptive cruise control (without lane keeping), the vehicle would brake suddenly and forcefully. This appears to be in response to a threat perceived by the car, but it would happen on totally clear roads, in great weather, without some of the typical false indicators experienced by "vision" based systems. It's noteworthy that both of my cars used the vision-only system, as this vehicle was one of the first ones that Tesla produced that did not include a radar-based system. I experienced phantom braking so often with this car that I was completely unable to use cruise control. On a ~1,000 mile road trip through Wyoming and South Dakota (with minimal traffic in clear conditions on well-marked roads), I experienced over 100 phantom braking incidents in 4 days of highway driving. After that trip, I never used cruise control again regularly, but I would occasionally attempt to see if it fixed itself, and every time I would turn it on, I would have a phantom braking incident within minutes. I was able to capture a few videos of this behavior that I can send, as well, but I apparently can't do that as part of this form so please let me know how I could provide those, if required. Finally, the dates that I'm entering below are for the first occurrence of the phantom braking that I experience, but between the two vehicles, I have probably had it happen to me 150-200 times now. I have since sold the second Tesla (largely to avoid these issues), but please let me know if I can provide more info. These cars are not safe right now, and I've been looking for a way to remedy that for a while.

My 2021 Tesla Model Y has two problems related to braking: (1) frequent unexpected and unnecessary slowdowns while driving on Autopilot adaptive cruise control. The vehicle seems to believe something is in the road but it is not the case. This has been called "phantom braking" by many online reports. I experience this on nearly every drive where adaptive cruise control is engaged. (2) On one occasion the car locked up its brakes and began swerving to the left for no reason whatsoever. An alarm appeared on the screen and audible tones and a video was automatically saved. The event lasted only a second but would surely have caused a collision if another car was following me. The event occurred as I passed an oncoming truck on a two lane highway at night in good visibility. I was driving manually. Adaptive cruise control and auto steering were *not* engaged at the time. The extreme braking event was caused by the Adaptive Emergency Braking (AEB) system.

Numerous times in the last 6 to 7 months, while driving my tesla on the freeway in auto pilot mode, auto pilot will just turn off and the car will abruptly slow down. Without reason, auto pilot turns off. And because of the settings on my car, this causes the car to quickly slow down. I rarely use auto pilot because I am afraid it will happen again and I’ll be rear ended.

After hearing of the "phantom braking" problem with the 2021 Tesla Model Y I thought I'd add my observations. My car has rapidly, unexpectedly, and without other warning decelerated several times but always when the forward sensors apparently picked up a car crossing in front of me. Normally, I'd appreciate the help but it has happened several times when the crossing car was well in front of me and there was no cause for alarm from me and no way a tailing car should expect such a dramatic braking action. Tesla should certainly be asked to review this system and modify the braking action so that it is more gradual for distant cars or preceded by a moderate sound alert for concerning but not immediately threatening front-crossing cars. I should also note that the warning sound seems to go off at appropriate times as I approach stopped cars and it doesn't brake inappropriately when I approach stopped cars. The only problem I've noticed is cars crossing in front of me, mostly from my left to right, when I'm still comfortably distant from that car. Hope this helps.

I have already reported this to TESLA and they did nothing for the following except to ask for a "time stamp". As I'm driving in Auto or Full self drive mode the car will suddenly brake as though there is something on the road in front of the car and at the time there is nothing present on the road or coming out into traffic. The car will make an alarm noise (internally) as though I did something wrong and as I said will decrease in speed dramatically and scare the driver behind me if there is a driver present.

While driving with cruise control engaged my car has now on several occasion suddenly and without warning applied the brakes on its own when there was no reason for the brakes to have been applied. Sometimes it has done it when a truck is approaching in the opposite direction, but sometimes it does it for no reason at all. Recently it did it with such severity that it was clear to me that if a car had been behind me I would have been hit from behind. Also, it was startling to the point where I could have lost control of my vehicle.

The driver assist feature was engaged, what TESLA calls FSD, full self-driving. This has happened multiple times where the car will slam on the brakes, even on the highway for obstacles not in the car's path. For example, a car is on the exit ramp and I am in the adjacent lane. The car on the exit ramp slows down to make its exit and the TESLA will slam on the brakes. The TESLA also has done this for cars making turns. It will not brake until the last second and then it slams on the brakes, even after the car in front of me has turned.

"phantom" braking occurred 2/17/22 ~ 630pm driving in parking lot, not in autopilot no people or other cars nearby went from 15mph to 0 instantly screen showed a person directly in front of car - no one there was foggy with light rain

After seeing news reports about the problems with Tesla "phantom braking", I realized this is not an issue localized with my vehicle. I also have this problem where the car will slam on the brakes when using the advanced cruise control system. It's jarring, to say the least. I reported the issue to Tesla a month after buying the car (10/21) and they instructed me to do a power cycle on the car but this has not helped. Incidenct occurance varies on the type of driving, but it's probably every 5 miles or so on a 2-lane road.

I am aware that NHTSA is investigating Tesla over the emergency braking issue when using its advanced features. When I have read articles about this they always reference auto pilot or full self driving. I wanted to make sure you knew that this issue also impacted adaptive cruise control. When I brought my Model Y home in August of last year I quickly learned I could not safely use the adaptive cruise control. I live in rural NE Iowa, and mainly drive on two lane roads. If I was on a downhill slope and meeting a vehicle with any kind of height to it the car would activate emergency braking, even though the other vehicle was completely in its own lane. It appears to me this issue has gotten better as updates have been issued the last six months and I have started to gingerly use cruise control again. It is common in the winter here to have tall piles of snow in parking lots. I also noticed on a sunny day I could drive right up to one of these piles when parking. It was striking that that huge pile of snow was invisible to the vehicle. Any other time I approach a barrier (e.g. pulling in to my garage) it gives all manner of warnings and a visual indication of how far you are from the wall. This issue would be much more dangerous if an analogous situation occurred using Autopilot or FSD. It is my understanding that for the 2021 Y Tesla went to just a camera based system (dropped LIDAR). I don’t know if that is what caused these problems or not. The car is a joy to drive. BUT, Tesla’s habit of releasing updates and features to the masses before they are fully tested is dangerous in my opinion. There are more Tesla’s on the roads these days, at some point the accidents are going to add up. The ability to update systems that control how a car is operated/functions is relatively new. I would offer that the processes around how these updates are managed should be the subject of a separate investigation.

Per previously reported cases, by Tesla Y suffers from “phantom braking” when I am using adaptive cruise control at highway speeds. In general it will decrease up to 20MPH very suddenly. This is always in response to a falsely detected hazard; it will sometimes do the same when passing a vehicle that has exited an off ramp and has break lights on but is no longer in my lane of traffic. in general i drive with maximum 5-6 car lengths in my adaptive cruise control and this should not be happening. This has been an intermittent but ongoing issue through 2021; have not experienced in 2022 but have not done a lot of high way driving. Scares the heck out of my passengers. Love the car but please fix the software or it will be my last Tesla.

I DO NOT DRIVE THIS CAR OFTEN, BUT WHEN I WENT ON A ROAD TRIP FOR TWO WEEKS OVER CHRISTMAS I NOTICED THAT THE CAR WHEN IT WAS IN CRUISE CONTROL WOULD PICK UP VEHICLES COMING TOWARD ME ON A TWO LANE ROAD AND SUDDENLY SLOW DOWN. IT GOT MUCH WORSE COMING HOME WHEN I WAS IN NEW MEXICO ON I25 GOING NORTH. IT WOULD SUDDENLY SLOW DOWN COMING UP TO A CREST OF A HILL WITH NO OTHER VEHICLE AROUND ME. IT ALSO PICKED UP SEMIS GOING SOUTH THAT WERE HUNDREDS OF YARDS AWAY FROM ME. IT HAPPENED NUMEROUS TIMES AND SCARED MY WIFE. WHEN I WAS HOME I SET UP AN APPOINTMENT WITH TESLA SERVICE. THEY LATER CANCELLED IT AS THEY DID NOT SEE IT AS A PROBLEM.

While driving on the interstate (divided) highway at 73 mph with adaptive cruise control engaged, the vehicle abruptly braked. There were no other vehicles or obstructions within 250' at the time of braking. No warning lights or messages appeared. To correct the situation, I immediately pressed the accelerator to increase speed. Conditions: daylight, dry road surface. If another vehicle was following close by this could have caused an accident. I've had the car about 7 months and this type of braking has occurred 7 times, all with no vehicles nearby. It has happened both in the daytime (6) and night (1) at similar speeds mention above. I brought car in for service at Tesla on two occasions for this problem and they could find no faults in the software or braking. Basically, I was told Tesla continues to update software.

Autopilot suddenly breaks to a dangerous levels while driving in the highway. Sometimes this happens with incoming cars/trucks on the other line. I have to manually take over control as I am worried I might be rear ended. These events are very likely to happen at least once on a given commute. This sudden braking also happens while going over a certain bridge. This has happened to all drivers in this car.

Phantom braking when using Tesla autopilot

This has happened multiple times. I am on the highway and have the cruise control set. The car suddenly decelerates but there is nothing in front to cause this. It is very jarring to me as the driver and to those behind me. When it happened during the day time I think it reacted to a shadow in the road from an overpass. It happened last night when it was dark. I had stopped using the cruise control because of the uncertainty, but decided to try it again on my trip yesterday. I received the car in September and I believe this has happened four times. I am reporting this now because I heard of the investigation. Now, I will keep closer track of the times, conditions and other facts. I have not reported it previously to Tesla, but will do so now. I looked on the Tesla forum and it is clearly a known issue.

The vehicle engages automatic emergency braking frequently and repeatedly without reason, especially on two lane highways with oncoming traffic. This occurs during the day and at night. The vehicle also engages phantom braking (without emergency braking notifications) during normal driving on freeways and highways. Video of this incident is also available.

North bound on interstate highway, my vehicle rapidly deaccelerated and then accelerated without warning

In 16 months I have experience 2 episodes of dramatic emergency braking while traveling at highway speed in the carpool lane adjacent to a concrete barrier wall estimated 5 feet high on the left side of the vehicle. The car decelerated from 65 mph to roughly 30 mph in roughly 2 to 2.5 seconds. Had someone been following at an unsafe distance an accident would have occurred. Thankfully it did not. I never experienced this in my previous Tesla Model S. Overall I love the vehicle, but these 2 incidents were disconcerting.

Hello, my Tesla Model Y frequently brakes unexpectedly causing me concern in traffic I could be rear-ended. This happens when engaged in FSD Beta software version 10.9 currently and has happened in all previous versions of the software as well. I have held a commercial drivers licnese and want everyone on the road to be safe as possible. The car brakes hard reducing speed 15mph in a second. The car has also attempted to take off from a red light when the first car at an intersection treating it as a stop sign when when several lights are present indicating a solid red and the screen in car shows me solid red as well. I have had to intervene many times to prevent accidents.

with cruise control on, when large vehicles (in their respective lane), would approach in opposite direction, the car would brake. Sometimes lightly, once (tour bus approaching) at 60 mph, the brakes were slammed on, with the car behind us nearly rear ending us

Phantom braking, rapid deceleration occur without warning and randomly.

Phantom braking, rapid deceleration occur without warning and randomly.

Car rapidly brakes when in cruise control and auto pilot. Will also rapidly brake when a car passes by. It will always be random and sudden. Also, occasionally the screen will turn off and I will lose the screen completely and not know my speed.

Two phantom braking incidents on loop 202 Wednesday night

When using basic Tesla Autopilot (AP) on side roads or highways the car will experience “phantom braking” with no other vehicles around. Phantom braking is where the car will slam on the brakes because it sees a safety issue ahead. I was driving on a highway at 60mph and engaged AP after about 5 miles the car brakes hard and fast down to around 40mph and then sped back up to 60mph after about 50 yards. It did this twice on the drive home. If we have an 18 wheeler behind us and they’re not paying attention they would definitely rear end our car.

The contact owns a 2021 Tesla Model Y. The contact stated while driving with the cruise control activated, the vehicle erroneously applied the brake. The contact stated that the brakes were immediately released independently of driver assistance. There were no warning lights illuminated. The failure had occurred approximately 6 - 10 times. The contact had not taken the vehicle to the dealer. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,000.

The adaptive cruise control and lane assist on the Tesla Y models are defective and pose significant risk to drivers, occupants and surrounding traffic. Phantom braking and sudden slowing are common place and many times unpredictable. Countless times when oncoming traffic in the other lane approaches, sudden braking and aggressive slowing will occur especially if this happens to be a logging truck or larger vehicle. Coming under any overpass or bridge will also produce phantom braking. This will happen countless times in a single trip rendering the adaptive cruise useless. I complained to Tesla and was called by the corporate office in Denver and told that this is a reality and it was my responsibility to "teach the neuro-net" that it's phantom braking was an error by accelerating aggressively during those episodes and producing "bug reports" to Tesla! I have had this Tesla 3 months now and have stopped using the cruise control and lane assist because of safety concerns. My attempts at "teaching" the computer the correct response has utterly failed. I have had 3 episodes that I know of that someone following closely behind me had to take evasive action which precipitated "road rage" type behavior on their part for no fault of my own. Tesla has made no effort to correct this defect and have even cancelled my repair appointments stating it was"not needed". Every Tesla owner I discussed this issue with has a similar experience. Eventually someone will get injured or killed due to this defect.

The cruise control on my Model Y frequently slams on the brakes for no apparent reason (no obstacle or vehicle in my lane). This happens at all speeds (from 30mph to 75mph). The cruise control is so unsafe and scary that I will not use it at all with other passengers in my car or when I have a car following me. My car slams on the brakes so hard it makes it completely unsafe for me and the people following me. In my opinion, it drastically increases the chances of being involved in a rear-end collision. There is no ability in the Model Y to use cruise control that is not adaptive-based. Until this problem is fixed, Tesla needs to offer a cruise control option that is 100% controlled by the driver (standard cruise) where the speed and brakes cannot be changed by the car. My car has not been inspected by the manufacturer and this has not been reported to the manufacturer because it is a widespread and known problem, and Tesla is not currently doing anything to help others who have reported the issue.

When driving with cruise control on I experience issues with sudden braking. Sometimes it seems like it may be an error due to on coming traffic (particularly trucks), but sometimes it’s due to blind curves or small humps (such as an interstate bridge/overpass) where the pavement is a different shade. Typically I’ll be at cruising speed 60-75mph and braking will be sudden and aggressive, to about 45mph. This has happened numerous times since purchase in June 2021.

I've been having problems with phantom braking, primarily on highways. This problem has gotten much worse in the last month or two. The car will unexpectedly brake while either autosteer or adaptive cruise control are engaged while driving on the freeway, and typically (although not exclusively) when my speed is approx. 70-80 MPH (where speed limit is 75-80 MPH). This will happen approx. once every half hour, although it is sporadic and often happens in spurts. Until about 1 month ago this would happen only while autosteer was engaged. However, during the last month or so ago this has also been happening while adaptive cruise control is engaged (without autosteer engaged). It happens most often when I am in the left lane passing a semi-truck which is in the right lane, although it happens other times as well. Always without any warning. It has happened a total of probably 20-30 times in the last 2 months (approx. 5,000 miles). Sometimes it manifests as a gentle, almost tentative tap on the brakes, whereas other times it is a fairly jarring with sudden hard braking. It has not caused any accidents or incidents, but I am concerned about it happening when a car may be behind me. Because of that, I will often disengage cruise control or autosteer if other cars are close behind me. My car software is equipped with Full Self Driving, but the FSD (beta) has not been downloaded.

While driving on C-470 in Colorado, eastbound approaching the Quebec St. exit, I was in the right lane. A car was exiting the highway while I continued straight. I was 2 sec behind this car and the car was in the exit lane, while I continued on the right lane. However, the highway curves to the left here. A straight forward view shows this car mostly in front of me. The Model Y braked excessively, from 65 to 45-50 before I could press the accelerator to continue forward. I would be worried of a rear end collision if there were a car behind me.

When the traffic aware of cruise control or auto pilot is engaged, particularly on two-lane roads with opposing traffic, phantom breaking occurs with about 90% of the approaching semi tractor trailers, and perhaps 25% of the approaching automobiles.

Phantom braking at all speeds both on city streets and on highways. On the highway 138 between Palmdale and Victorville California I was unable to use cruise control because the car would continually brake. I was the only car on the road at the time.

My Tesla Y suddenly decelerates while in cruise control at the same location on a highway. It occurs when I am passing an exit ramp, but not exiting. The car reads the exit ramp speed of 45 and suddenly decelerates from. 65 to 45. It never reads exit ramp speed when I am not using cruise control and am exiting.

The contact owns a 2021 Tesla Model Y. The contact stated while driving at highway speeds with the cruise control activated, the vehicle had erroneously applied the brakes causing the vehicle to reduce the speed. The failure had occurred on multiple occasions. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 10,000.

I have had issues since i purchased this vehicle in march of 2021 where driving down the highway with Adaptive Cruise Control enabled and it will suddenly slam on the brakes at highway speeds with no other vehicles around. This sudden braking is so severe at times that everyone in the car is thrown forward and bracing for a false impact. This has caused several close calls for vehicles following me. Also the severity of the braking in winter weather causes the vehicle to lose traction and potentially place all the occupants and others on the road at risk. During my time in the FSD Beta program i was able to report all of these events, sometimes dozens of times a day. Eventually I asked to be removed from the program as it seemed worse in the program than when on a standard build version of the software.

Our Tesla started last month braking suddenly and hard when cruise control was enabled. This is happening at night when cars are passing us going in the opposite direction. At no point did the braking occur due to cars actually being in our lane or potential accident. These braking errors happen when normal driving conditions under or at the speed limit with clear visibility.

While driving at highway speeds I have recently had repeated unexpected breaking events occur while using adaptive cruise control. It happens without warning and for no apparent reason. The breaking is significant and could easily result in a rear end collision.

I too have had an issue were without warning or provocation when on cruise control, whenever a semi-truck approached in the oncoming lane, or on four-lane divided highways, my car decelerated from 75 miles per hour to 40 miles per hour in a matter of seconds. I have also had the car phantom break when going under a overpass on a highway and while crossing 2 lane bridges. Luckily no accidents so far but definitely terrifying.

This car is subject to frequent "phantom braking" . Using adaptive cruise control or full self driving, the car will occasionally brake hard for no logical reason. This happens every time I drive the car on two lane roads, i.e., with vehicles approaching from the opposite direction in the opposite lane. It happened from the time I took delivery until the present. It happened today (2-17-22). In 90% of cases, the phantom braking is triggered by a large vehicle - semi truck or bus, approaching from the opposite direction. In 10% of cases, the cause is either not clear, or caused by a smaller vehicle. The phantom braking occurs in all lighting conditions - right sunlight, overcase, night. The vehicle has not yet been inspected by Tesla.

On 2021 August 18 Wednesday at approximately 2:40 pm (Eastern time USA) and again at 2:59 pm, my Model Y braked severely while driving at high speed. Weather: Moderate to heavy rain due to passage of the remnants of Hurricane Fred. Location - incident 1 (about 2:40 pm): Pennsylvania Turnpike eastbound, just west of the Somerset exit. Location - incident 2 (2:59 pm): PA 219 South (limited-access expressway) near Meyersdale, PA. Situation/speed - incident 1: (2:40 pm): Driving in the passing lane traveling at approximately 70 mph. Cruise control was engaged. Situation/speed - incident 2: (2:59 pm): Driving in the passing lane traveling at approximately 70 mph. Cruise control was engaged. Description of incident (2:40 pm): The incident happened on a downhill curve while passing another vehicle when the Model Y braked suddenly and sharply. The speed dropped from approximately 70 mph to approximately 40 mph. The area was a construction zone but not an active construction zone at the time. There were construction barrels and flags on the shoulder of the left lane. There were concrete Jersey barriers/K-rails in the median strip between the eastbound and westbound lanes. The lane markings were visible but may have become obscured by rain/mist and a vehicle in the right lane. There was no vehicle behind the Model Y. Description of incident 2 (2:59 pm): While passing another vehicle the Model Y braked suddenly and sharply. The speed dropped from approximately 70 mph to approximately 55 mph. The area was a staging area for a construction zone but not an active construction zone at the time. There were construction barrels and flags on the shoulder of the left lane but no other barriers or fences. The lane markings were visible but may have become obscured by rain/mist and a vehicle in the right lane. There was no vehicle behind the Model Y.

On 2021 August 18 Wednesday at approximately 2:40 pm (Eastern time USA) and again at 2:59 pm, my Model Y braked severely while driving at high speed. Weather: Moderate to heavy rain due to passage of the remnants of Hurricane Fred. Location - incident 1 (about 2:40 pm): Pennsylvania Turnpike eastbound, just west of the Somerset exit. Location - incident 2 (2:59 pm): PA 219 South (limited-access expressway) near Meyersdale, PA. Situation/speed - incident 1: (2:40 pm): Driving in the passing lane traveling at approximately 70 mph. Cruise control was engaged. Situation/speed - incident 2: (2:59 pm): Driving in the passing lane traveling at approximately 70 mph. Cruise control was engaged. Description of incident (2:40 pm): The incident happened on a downhill curve while passing another vehicle when the Model Y braked suddenly and sharply. The speed dropped from approximately 70 mph to approximately 40 mph. The area was a construction zone but not an active construction zone at the time. There were construction barrels and flags on the shoulder of the left lane. There were concrete Jersey barriers/K-rails in the median strip between the eastbound and westbound lanes. The lane markings were visible but may have become obscured by rain/mist and a vehicle in the right lane. There was no vehicle behind the Model Y. Description of incident 2 (2:59 pm): While passing another vehicle the Model Y braked suddenly and sharply. The speed dropped from approximately 70 mph to approximately 55 mph. The area was a staging area for a construction zone but not an active construction zone at the time. There were construction barrels and flags on the shoulder of the left lane but no other barriers or fences. The lane markings were visible but may have become obscured by rain/mist and a vehicle in the right lane. There was no vehicle behind the Model Y.

Phantom breaking while driving with cruise control.

On almost all my long highway trips (about 4 hours long), if I have traffic aware cruise control (TACC) enabled on my Tesla Model Y, I experience one or more episodes of phantom braking. The first time it occurred I had owned the car for only a few weeks and was not yet accustomed to its fast acceleration. I was driving at about 70mph on a clear day with no one in front of me when the car suddenly braked. My first impulse was to hit the brake to disengage TACC, but I realized that would slow down the car more, increasing the chance I might be rear-ended. So I hit the accelerator and rocketed back up to 80mph before settling back to normal speeds. I was fortunate to be on a straightaway with no one ahead of me. Since then I have experienced phantom braking with TACC enabled under similar circumstances, i.e., with no cars or trucks in front of me and in clear weather in daytime. With more experience, I have noticed that the problem happens more often when I am passing a truck on the highway, especially when doing so around a curve. In past years I have driven numerous rental cars with adaptive cruise control and have never experienced anything like the phantom braking of the Model Y. This is not normal behavior and I hope you can get Tesla to fix it.

While driving in autopilot the car will randomly slam on the breaks multiple times at all speeds from 30-60mph even when the road is empty. This can increase if a large bus/truck is on the other side of the road in the opposite direction.

Anytime we are using the adaptive cruise in our Model Y, we have experienced "phantom braking" issues where the car suddenly brakes for no apparent reason, decreasing cruising speed from 60-70 mph by as much as 20 mph all at once. This mostly occurs on two lane highways and with oncoming vehicles that are larger (truck, etc.). Also sometimes occurs cresting a hill. It happens so often that we do not use the crusie control feature unless we are on an interstate with dividers between oncoming traffic and ourselves. Any rural two-lane highway causes multiple incidences of "phantom braking" every time we use it. Literally happened dozens of times at this point.

We are familiar with managing the controls which, in my experience, operate similarly to other vehicles with similar safety and driver-assist features. Unfortunately, in regards to the effectiveness and ease of operation of the TACC, our Tesla is by far the worst of the 5 vehicles with which I'm familiar. The experience of managing TACC with oncoming traffic is frustrating, distracting and sometimes unsafe. Autosteer, because it builds on TACC's systems, is similarly deficient although the features it provides would be extremely welcome when TACC is improved. Nearly every oncoming large truck (including many pickup trucks) caused TACC to brake the car TACC assisted braking was inconsistent. Sometimes an immediate, slight reduction in speed (5-10mph) and other times it was an immediate major reduction in speed, on the order of half-speed within 3 - 5 seconds. It was common to have the car brake from 65 - 35 for no other reason than a large, oncoming truck. After 3 or 4 occurrences of heavy braking, I would turn off TACC and manually maintain speed with the accelerator. This in itself is fatiguing and I would eventually resort to a system in which I would disengage TACC when approached by a truck, usually 200 - 300 yds away and then reengage when traffic was clear Heavy braking was severe enough that, if a there had been a closely following/unaware car, it would have rear-ended our vehicle TACC (and Autosteer) seem "happiest" when following other vehicles and, even on 2 lane highways, phantom braking was much less frequent A standard cruise control (no Traffic Assist except for Following Distance) is not available but would be welcome Summary: On the Interstate Highway system TAAC works reasonably well but could use improvement. On 2 lane highways TACC is more work and less safe than operating the vehicle manually and, as a system designed to reduce driver workload and improve safety, it fails.

Several times over the past 6 months the car suddenly slowed down without any reason while driving on autopilot with nothing ahead of it on highway (there was no change of speed limit so that can’t be an explanation). Also known as “phantom breaking”

I’ve been driving my Tesla mostly under autopilot about 90% of the time over the past 4 months. During that time, I’ve experienced about 30 or more phantom braking issues where the automatic braking system will engage when there is no object in front of the car. It’s all happened when autopilot was engaged. It happens during the day, generally on a single lane road, and also at night when on coming traffic lights are blinding. Each time it causes the car to rapidly slow down and causes the car behind me to slam on their brakes, potentially causing an accident. This needs to be fixed since it’s safety risk.

Traffic aware cruise control frequently hard brakes / emergency brakes on 2 lane roads when large vehicles such as semis and dump trucks approach in the opposite direction even though all vehicles are properly in their respective lanes. This presents a serious risk of being rear ended as well as heart attack for startled passengers. TACC is so bad it's not just unusable it is unsafe.

While using TACC ( traffic aware cruise control) the car would suddenly break and beep warning sounds. Happened randomly and at various speeds but seemed to correlate most with trucks in the left lane. Some colors seemed to be picked up more than others. Bridges and shadows also triggered it. It was my first long trip in the Tesla Y and so experienced these horrible, unpredictable episodes around 40 - 60 times during an 8 hour drive mostly on highways - many of them two way

When using the cruise control (and, by extension, Autopilot) feature, the car often brakes unexpectedly and in some cases dramatically for no obvious reason. I often use cruise control on single lane undivided roads that have speed limits between 35-50mph. When using cruise control in this scenarios the car will often automatically apply the brakes for no obvious reason, often applying the brakes hard enough that the car slows down quickly. Many times the forward collision warning sound is played but there is nothing in front of me in my lane or in the opposite lane. Other times this happens when a car is approaching me in the opposite lane. There have been several cases where the car applied the brakes for no obvious reason so hard that had I not intervened (by pressing the accelerator) the car behind me would have been at risk of hitting me. It has gotten to the point where I am becoming somewhat conditioned to override the automatic braking anytime it happens. That is dangerous and can lead to an issue where the car legitimately has a reason to decelerate but I override it thinking it is braking for no reason. I see this behavior in both cruise control (which Tesla calls Traffic Aware Cruise Control) or in Autopilot. I don't currently have the Full Self Driving feature of the car. It occurs most often when I'm on a single lane undivided road using either cruise control or Autopilot. When I'm using cruise control or Autopilot on a traditional divided highway the unexpected braking happens much less frequently.

While using adaptive cruise control driving at the I-25 speed limit in northern New Mexico on Feb. 5, 2022, when I went to pass a tractor-trailer rig on a left-turn stretch of freeway, the brakes suddenly slammed on hard (phantom braking), though there was no endangerment in the driving situation. This happened twice on this trip. In both instances, it was while legally passing a big rig on the interstate at the speed limit, with our car in the left lane and the truck in the right. We've taken this vehicle on long interstate road trips through the Mountain West before, and never encountered this problem before in similar circumstances. There must have been some software upgrade that made the car more dangerous and unreliable to drive while using cruise control on freeways with tight bends. Now I don't trust the vehicle and won't be using cruise control until this problem is remedied.

First, the car was not in auto pilot mode or cruise control. The car was driven into the garage, 22 inches from the landing and put in park. The “P” was lit so it was in park when it suddenly lurched forward and hit the landing and the four way flasher came on. Damage has been repaired but was $2500. Per Tesla, the car was not at fault and the car functioned as intended but it was driver error. With all the safety features that this car has, why did it not sound a warning or apply brakes to prevent this from happening. I have read about hundreds of thousand’s of incidents of sudden unintentional acceleration but yet nothing has been done about it. There is another problem with phantom braking when the car suddenly stops if you use the cruise control. I do not use cruise control because of this problem. Tesla continues to add games and other nonsense but have done nothing to fix these problems. I reported this to the Minnesota Attorney Generals office and they suggested that I contact the nhtsa. Their response from Tesla was also that it was driver error and it was not, the car was in park.

Slams on the brakes without warning. Almost caused semi to hit me from behind. This is very dangerous and must be fixed.

PHANTOM BRAKING When cruise control is engaged (not auto steer or full self driving) the vehicle will intermittently slow down or apply corrective braking when no hazard exists. This happens more frequently on 2 lane roads but also happens occasionally on multi-lane freeways. On a 2 lane road, my vehicle will either slow down, brake or break HARD when anything larger than a SUV is coming from the other direction at normal speeds and in his lane. I have also experienced this when there is nobody for 1+ mile in front of behind me. If there are cars behind me, I find myself covering the accelerator and ready to floor it in case my car suddenly slams on the breaks. This make cruise control very unsafe and stressful. I have another Tesla vehicle doing the same thing and will post separately on that one. Thank you. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Issue #1 When on autopilot, vehicle can suddenly brake on its own (phantom braking) without warning. This happens frequently on major highways and in some instances I have to respond quickly to prevent rear end accidents. Issue #2: Vehicle only alerts when another vehicle is suddenly stopping in front and does not automatically brake as required.

This is another incident of "phantom braking" that affected my wife and I- which occurred on Feb. 7th, 2022. We were returning from a trip to Michigan and headed back to Chicago-area at about 2 PM ET. The same exact scenario unfolded as the incident on Feb. 1st ( when we were driving TO Michigan. ) This time we were on I 94 headed WEST toward Chicago. There was a truck approx. 150-200 ahead of us and in the lane to our right. I was driving in Autopilot. All the cars on my highway were headed in the same direction all headed west to Chicago. So the phantom braking was not triggered by a truck in an opposite-headed lane. It was triggered by a truck headed in the same direction and to the lane to my right- the same exact scenario as what happened on Feb. 1st. Almost identical configuration. I was doing about 60- frankly paranoid that the car could stop throughout our whole trip home. Sure enough, when we approached the arrangement where a truck was ahead and to the right of our lane, the car suddenly braked. Luckily there was no vehicle tailgating us. So that's it. It happened again. All told, this is about 8th incident of phantom braking on the expressway.

on the 2022 Model Y, they have an Emergency Braking issue when the cruise control is set and you meet an oncoming car the Model Y will slam on its brakes.

The vehicle will randomly brake with no traffic in broad daylight (shadows cast by trees?), or always at the same area (e.g. when entering or exiting Sumterville, FL from the south), or when a large vehicle is approaching from the opposite direction (such as a semi rig), often producing an audible alert but at times without any warning. My previous vehicle, a Model 3 equipped with radar and the old software still relying on it for input, would also produce phantom braking events, but only in small numbers. The new Model Y with vision only is unreliable and dangerous, and practically useless when adaptive cruise control is engaged. This has been occurring since day one. Never before have I experienced such dangerous behavior in any prior vehicle, let alone one as modern and expensive as a Tesla.

Numerous phantom breaking incidents. Dangerous

blind spot warning on the lower left corner of the screen, which is covered by the right hand when driving. With the turn signal, it is impossible to the blind spot warning video without taking the right hand off from the steering wheel. A dangerous situation trying to turn the vehicle with one hand! Also Tesla model Y phantom breaks every time I used autopilot on interstate. Fortunately, no vehicles were behind me. An accident waiting to happen.

Like many other Tesla owners, I’m having daily problems with phantom braking when using my adaptive cruise control.

This is an ongoing issue. When using autopilot, I experience phantom braking, usually with large oncoming trucks on 2 lane highways. The problem is worse with logging trucks, but I've had it happen with vehicles as small as school buses. In the worst cases, the collision alarm sounds and the car slows up to 30mph immediately. I have this happen at least twice every morning on my 7 mile drive to town. I have videos that capture this event. Photos don't work

When we were driving in cruise control and auto pilot on two different trips, the car would brake for no reason We experienced dramatic breaking -Frequently up to 20 mph. These incidents would occur when a car was approaching us on a 2 Lane Highway but often for no apparent reason. We feel this poses a high risk of rear end collision if a car is behind us when it breaks

I was driving on a 2 lane highway using cruise control and the car suddenly aggressively slowed down. I have owned the car since October 2021 and this is probably the 15th phantom breaking event that has occurred. Cruise control on this car is not trustworthy nor safe on a 2 lane non-divided highway.

When using cruise control on two lane secondary roads the brakes are activated when a large truck approaches from the opposite direction causing vehicles behind me to have to brake unnecessarily. The cruise control is virtually unusable when not on a limited access highway.

While traveling at night on a 2-way highway at about 65-70mph my vehicle incorrectly thought every semi-truck I encountered was in my lane and would apply hard braking. This has happened 10+ times.

On February 1st, 2022 I was driving with my wife from the Naperville, IL area to Holland, MI. We were on I 94 headed east, approximately 20 miles west of Michigan City Indiana headed east. I was driving around 65 miles per hour. We were on a 4 lane highway- all the cars on those 4 lanes were headed in the same direction. There was a truck in front of us ( headed in the same direction ) that was located to the right of us in the lane to our right and it was about 60 or 70 feet in front of us. All of a sudden the car, that had been operating on Autopilot, braked suddenly. We went from 65 to almost 0 in a split second and if my wife and I weren't wearing seat belts we would have been very seriously injured. My neck suffered a whiplash and I'm still in pain several days later.

Phantom braking hard braking on freeway with no cars or objects around

FSD, the design of FSD using the safety score is designed to defeat failure reporting to government agencies. If you allow the FSD system to drive on its own, it will crash, run into things, fail to stop, or stop at green lights constantly. What the driver score system does is force human beings to manage and mitigate its failures leaving a on paper result that the system is more safe than drivers driving on their own. This is 100% false, if you allow FSD to drive, it will fail almost 100% of the time in very quick succession. From lane change mistakes, to turning mistakes, not staying within its lane in a consistent manner, not putting the car into left turn lanes or stopping at green lights, which in itself is dangerous. The safety score system MUST be eliminated as it cherry picks those drivers willing to spend the time and energy to ANTICIPATE the failure/weakness of the software and mitigate its failure before it fails, thus providing the government with false "safety" numbers... Grab a car and drive it, it will not be long before it fails left and right!

I commonly will experience phantom breaking driving on two-lane roads, particlualy when meeting oncoming traffic. This occurs most commonly at the crest of a hill or when meeting trucks. It occurs nearly 100% of the time when meeting trucks at the crest of a hill. There are also random occurrences on flat roads with no other vehicles and no shadows or bridges. It also occurs on bridges and occasionally with shadows. Performance has been better on four lane roads with more traffic. It's as if the system needs to have other traffic to gauge itself. With no traffic on four lane roads, phantom braking will rarely occur. There is no single date of this occurrence. It happens ALL THE TIME.

I am driving down the highway and the car brake checks hard 3 separate times one one occasions for no reason while using Auto Pilot.

While driving in my car on a highway in cruise control, my car will break very hard for no reason. It’s as if it is detecting a car in front of us and it disengages cruise control very abruptly. It can be very scary especially if there are cars behind us. I no longer dare to use cruise control because it has happened multiple times. I have not discussed this issue with the dealer and there were no warnings in the car at the time.

The Tesla has been doing phanton breaking. For example on the highway using dynamic cruise control or autopilot. When a truck is merging to the right lane it will apply quite the break force. Almost got rear ended cause of this on the highway. Observed this a few times on drive from Ga to NJ. I also noticed going up and down hills with dynamic cruise control it will sometimes trigger the front collision warning or phanton break. This seems to be sporadic and doesn’t like one lane back roads. Last and it least I also noticed that using auto pilot the car forces you to use auto high beans. On the highway at night it will go off and on a lot to the point drivers on opposite side of the road would flash their lights to let me know about the high beans. The model teslas doesn’t use radar or laser sensors like previous year. It does seem to have a lot of impact cause I did not see these issues with my Lexus RX350 With dynamic cruise control, lane keep assist, auto high beans, and front collision warning.

On the highway at night it will go off and on a lot to the point drivers on opposite side of the road would flash their lights to let me know about the high beans. The model teslas doesn’t use radar or laser sensors like previous year. It does seem to have a lot of impact cause I did not see these issues with my Lexus RX350 With dynamic cruise control, lane keep assist, auto high beans, and front collision warning.

The Tesla has been doing phanton breaking. For example on the highway using dynamic cruise control or autopilot. When a truck is merging to the right lane it will apply quite the break force. Almost got rear ended cause of this on the highway. Observed this a few times on drive from Ga to NJ.

This car is exhibiting random “phantom braking” incidents when cruise control or auto pilot is engaged. In EVERY incident the road is clear ahead and in the adjacent lanes, with no other vehicle traffic. The car will appl full emergency braking for no reason, and with no warning

Phantom braking

Phantom braking

When cruise control is active, the car slams on the brakes for no apparent reason. This happens basically every time I drive the car. I’m always concerned it will cause me to be rear-ended.

The car experiences phantom braking when adaptive cruise control is engaged. Happens most often when going under an overpass but has happened on clear open roadway as well (no cars around).

Phantom braking. I can’t use the cruise control at all because it constantly brakes and swerves when nothing is in front of the car. I took the car to the device center and was told they can’t do anything.

When driving with Adaptive Cruist Control on, the car will randomly slam on the brakes (phantom braking) for no reason. It can be with a shadow on the road or, VERY commonly, when any car or large truck passes on a 2-lane highway or road. It's extremely dangerous to any cars behind and to myself.

The vehicle brakes out of no where when on autopilot. Phantom braking

When cruise control (TACC) enabled the car will brake on 2 lane undivided roads when oncoming vehicle is a semi or other large vehicle. Vehicle may suddenly slow 5-15mph causing unsafe condition if being followed closely. Problem is easily reproducible on any 2 lane road. Will also occur when autopilot engaged as autopilot is simply TACC with lane keeping. The features otherwise seem safe on interstates and divided highways.

From June, 2019 to June, 2021 we owned a Tesla Model 3. We have had the Model Y since June, 2021. The current Model Y has a significant phantom braking problem. Worse than the Model 3 that we owned. Our Model Y relies on "Tesla Vision" without radar. Last week we drove 1,400 miles from Montana to Southern California. On more than a fifteen occasions phantom braking occurred, to the point that we were reluctant to use it. Driving on an Interstate at 80 mph, the car would suddenly brake. The 1st reaction is to overcome the braking with acceleration. On one occasion when there was no traffic behind, I didn't accelerate until 45 mph. From 80 mph to 45 mph suddenly. Dangerous. On city streets we also experienced phantom braking, yet not so dramatic. Some thoughts on what causes this issue: pavement glare, a change in pavement color, concrete barriers on an overpass, reflection from on coming traffic. Traffic Assisted Cruise Control is an important feature for me and now I'm reluctant to use it.

Vehicle abruptly applied automatic braking as I was cruising at 40 mph. Went to an almost complete stop in a short distance. No one was behind me but if there were it would have been dangerous. Also, there were patches of ice in the road which made it even more dangerous.

Frequent phantom braking when in cruise control. The vehicle unexpectedly brakes often while in cruise control when there is an oncoming vehicle in the oncoming traffic lane, despite the fact that both my vehicle and the oncoming vehicle are in their respective lanes (in other words there is no apparent danger of collision). The phantom braking also sometimes happens apparently at random, in other words when I can't see anything in the vehicle pathway that could be interpreted as dangerous. I am entering a date under "Additional Details" below, but this has happened repeatedly on many different dates.

When using AutoPilot, the car will without any basis or immediate need brake most abruptly without any due cause, as there is no traffic or cars around it. It’s usually when passing over overpasses but not always. This sudden deceleration has almost caused accidents. Only me being wary and cognizant has saved the car from being rear ended. Sometimes there’s no cars around but it still can be very dangerous. This has been happening over almost a year and Tesla has not done anything to address this widespread issue.

Sudden, unexpected breaking multiple times while using autopilot cruise control.

Sudden, unexpected breaking multiple times while using autopilot cruise control.

On multiple occasions when auto pilot engaged, car will suddenly brake with extreme force. I have not been rear ended because of it, but it could very well happen. On Jan 30, as an example, travelling on divided 4 lane highway, no one in front of back, autopilot engaged, for no reason, it tried to come to a sudden complete stop while going 70mph. There was nothing in the road whatsoever. MULTIPLE other instances of this. On 2 lane roads, this happens even more frequently, I would estimate once every mile, though not always as severe.

phantom breaking issues on 2 lane roads.

phantom breaking issues on 2 lane roads.

Traveling at 70mph on a highway with no cars in front using Autopilot with steering assist. The car suddenly braked hard and came to almost 35mph before quickly regaining speed. Had a car behind me that could have rear ended me on the highway. This was one of many times has happened but this was the most severe.

Chronic problems with phantom breaking. We’re deathly afraid of getting rear-ended on the interstate. It’s a scary situation - we’re terrified.

Experienced "Phantom Braking" several times when cruise control is activated on a highway.

I was driving north on I-5 in southern Washington on a sunny Sunday morning with low traffic in October 2020. I had only had the car for a few days and was using the autopilot and cruise control for the first time. As I approached an overpass that was casting a shadow across the highway, the car suddenly braked hard. Fortunately there were no vehicles immediately behind me. If there had been, I likely would have been rear-ended. About 15 minutes later, while driving in the middle of the three northbound lanes, a motorcycle passed me on the left and then cut across my lane to get to an exit. Again, the car braked suddenly. When I next stopped to charge the vehicle, I went online and read on various Tesla user chatrooms that this was a widely experienced problem. I immediately stopped using the autopilot and cruise control. I have not used them at all in the past 15 months.

Vehicle will randomly reduce speed when using the adaptive cruise control.

I have consistently experienced “phantom braking” when using cruise control. (I do not use full driver assist). I drive frequently on two lane highways and the braking occurs seemingly randomly, sometimes even when no other vehicles are close enough for concern, but usually when a large truck is approaching on the opposite side. I don’t recall having the problem while driving on divided highways. Each time this has occurred I am startled by the warning beep and am in fear of a rear-end collision, so I have stopped using cruise control except on multi-lane, divided highways. I read about “phantom braking” in the Washington Post and was surprised that there were not more similar complaints.

On numerous occasions while using cruise control the the Model Y brakes would be suddenly applied in the following situations. While in the inside lane of a curve in the road when several approached from the other direction the brakes would be suddenly applied when the front of the Model Y was pointing at one of the middle vehicles in the line of approaching vehicles. This sudden braking does not happing when traveling down straight sections of roadway or when traveling in the outside lane of a curve.

I just want to add my name to list to complain about phantom braking. You can't trust the adaptive cruise control to maintain correct speed as it will at random times brake hard when there is nothing in front of you. Maybe 20% of the times I use it.Sometimes it looks like a shadow on the road will cause it, maybe at night and when the weather is bad. It brakes hard too and you have to be ready to compensate. I think it is from using just cameras and no radar in my newer model

When driving on divided interstate highways using adaptive cruise control the car would suddenly without warning brake heavily. This is happening up to five times a day on long trips. Weather was clear, no other cars in front and no obstacles on the road. The only recourse was to slam the accelerator to the floor and hope no one was tailgating. This has also been happening on two lane roads when a truck or other large vehicle approaches. This was so dangerous we can no longer use the feature on two lane highways.

Driving a 4 lane road with not other vehicles in site the car suddenly braked to the point of locking up the seat belts and throwing items around the cabin. I reported this to the manufacturer and they were able to review logs and confirm that the car mistakenly saw something and applied the brakes. I would have been hot from behind if a car was following. I was told not to use this feature on certain roads. But I asked how to disable it I was told there is no way. This needs to be addressed before there is an accident. I was not using full self driving. I only had cruise control on.

While using cruise control, aka “Autopilot,” the brakes automatically engage, even with no reason to. It’s happened so many times at high speed, and while passing, that I am now scared to use “autopilot.” While using autopilot, I have to be ready to mash the accelerator peddle at any moment, due to unwanted breaking and it feels very dangerous. It can also be traumatic for passengers when the vehicle suddenly brakes hard at high speed. I’m worried it could also cause an accident if someone were right behind me and also traveling at a high rate of speed.

Unexpectedly slamming on my brakes in response to imagined hazards, such as oncoming traffic on two-lane roads. This happens often and I have to shut off this feature to avoid a spin out on icy roads. Very hazardous. overly sensitive to trucks in the opposite lane. Car lurched from 50 mph to a near-stop in response to a large truck. Is this phantom braking?

The contact owns 2021 Tesla Model Y. The contact stated that while driving approximately 55 MPH with the vehicle on auto pilot, a large commercial truck in the opposite lane passed the vehicle, which then applied the brakes and slowed from 55 to 35 MPH. The contact stated that this should not have happened and was an instance of "phantom braking". The contact reported that once the commercial truck passed the vehicle went back up to speed within seconds. The contact stated that he did not notice if a warning light was illuminated, but the contact stated that he heard the vehicle sound an audible beep. The contact did not take the vehicle to a local dealer to be diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure; however, the contact went to the dealer to report the failure. The failure mileage was approximately 1,000.

Mileage: 1,000

(1) My car dangerously and aggressively applies the brake dropping the speed of the car between 3 to 30 mph within a second or two (phantom breaking) EVERY SINGLE TIME I drive the car in adaptive cruise control or auto steer. This happens on 2 lane roads, on divided highway, driving on straight and curvy roads, when there are shadows, frequently when a truck or car is coming toward me, and even on overcast days when driving on a freeway when there are no shadows and no traffic in either direction. The car seems to be sensing an object that is going to cause a collision and applies the brake even when no object, threat, or shadow is anywhere in view in any direction. I frequently have to immediately step on the accelerator to keep from getting rear-ended in what could be a severe or fatal accident. (2) On a 225 mile drive to the Tesla Service Center to correct the phantom braking problem, my car inappropriately applied the brake 40 times, including aggressively dropping the car's speed from 63 mph to 35 mph in a second or two. (3) My car dangerously and aggressively applies the brake whenever a car is turning in front of me that is sufficiently far enough away that there is no absolutely no threat whatsoever of a collision. I then have to quickly step on the accelerator to keep from being rear-ended. (4) I have taken the car into the Tesla Service Center twice to correct this problem. I even gave them a list of dozens of times/dates I experienced phantom braking and the # of mph the car slowed (I recorded this on paper and as "bug reports" on the car's computer). On one visit the technician spent 12 hours reviewing my bug reports and the car’s operation. In both of my Service Center visits the bug reports were sent to a Tesla engineer for review. After both visits to the Service Center I was told the technician and the engineer could find nothing wrong with the car and “it was working as designed.” (5) In conclusion, my Model Y has a SEVERE safety defect.

In short: Phantom Braking While driving on single lane highways with Autopilot enabled my car slams on the brakes and alerts whenever a semi is safely approaching. What component or system failed or malfunctioned, and is it available for inspection upon request? - I assume the Tesla Vision System + Autopilot are what fail in this scenario. How was your safety or the safety of others put at risk? Immediately this puts us in risk of a rear end collision. Alert fatigue from false alarms creates a long term risk as drivers are trained to ignore / cancel alerts. Has the problem been reproduced or confirmed by a dealer or independent service center? Not explicitly. We have mentioned it to a dealer and said it was a common complaint. Also it is a well known (under addressed) issue amongst Tesla owners. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, given the lack of property or personal injury it doesn't seem right to alert those institutions. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, all systems appear to be functioning correctly. That is a large part of the problem - if the Tesla Autopilot is unable to function reliably on one lane highways it should at least warn drivers.

I drive on the highway from Dallas to Austin to Houston every week. Every trip I have about 2-4 phantom braking incidents at full speed. It seems to occur at similar points every time. It is incredibly alarming and I have to slam on the accelerator to not cause an accident. This needs to be repaired.

When using cruise control. My car will phantom brake. Most of the time it is when oncoming traffic is present… but a few times there are no cars around me… a few weeks ago, the car phantom brakes on an ice patch almost causing a wreck.

Automatic Emergency Braking. Known also as "phantom braking." Tesla is aware of the problem. Regardless of whether or not I'm using the standard cruise control or the more advanced full self driving feature, the car routinely hits the brakes even when there is no obvious obstruction in front of it. If the car suddenly brakes on the highway with another car behind it, it risks a rear end collision. No other warnings appear. The car simply brakes for no reason. This automatic emergency braking system should be removed for standard cruise control. It's more of a hazard than a benefit.

phantom braking, my car have driven 13.6K miles in the last 1 years. It happened once on the city street (early morning with no cars on the road and twice on the freeway, both time I was next to a big trailer truck, and no cars behind me, lucky.

While using adaptive cruise control the vehicle will suddenly brake. I thought it would get better after it’s system learned but still happens when a large vehicle or even a pedestrian is in an adjacent lane. Car has 3940 miles on it now. Last highway trip of 100 miles it happened five times. I don’t know how badly it brakes now because I keep my foot on the gas pedal while in adaptive cruise control so I can react quickly to it. We previously owned a 2018 Tesla 3 with radar enhanced “auto pilot” and did not experience this problem.

Each time I'm on a two lane rural road (one lane on each direction with the double yellow line between the lanes) the phantom breaking is unbearable (MYLR vision only). 90% of the time if there is a large truck going on the other side, Autopilot will slam on the breaks and beep like crazy thinking that the truck is going to hit me head on. I don’t think it is the forward collision warning as this never happens when I don't use autopilot.

Car randomly breaks while in autopilot mode. Very dangerous since someone can crash into me from behind. There is nothing on the road in the way and no emergency vehicles nearby and no stoplights or stop signs when this happens. The car does not always notify of blind spots when backing the car up.

Multiple times we have been on empty open roads traveling at 60-70 mph only to have the vehicle slam on the brakes and slow down to approximately 30-50 mph. There are no obstructions on the road or oncoming vehicles when this happens. This has been reported multiple times to Tesla and I have been told their are no issues and the the car “must have seen something on the highway”. This is totally untrue. The vehicle will also slam on the breaks in 2 lane highways if a large truck or semi is traveling in the opposite direction.

While driving on the freeway at 70 mph with cruise control activated, the Tesla suddenly braked hard. There was no emergency or vehicle entering my lane. This occurs on a regular basis, more so when passing a semi or large vehicle. Vehicles behind me have to brake or swerve to avoid hitting me. I have notified Tesla Service about the issue and their response was they know about the issue. I was told to keep my hands on the steering wheel and pay attention....UNACCEPTABLE!

Phantom braking!! It's happening almost everytime I engage autopilot and it's unfortunate because this system would be amazing if it wasn't do this issue. Anytime I'm in a 2 way highway and I have a semi or a large vehicle coming my way on the opposite lane it decides to slow down from the speed limit around 75mph in Texas all the way down to 35mph, which makes for a dangerous condition and puts me at risk of getting rear ended. I have reached out to Tesla Service and they said they can't do nothing about it. I have videos of these incidents but it seems like I can't upload on these Forms. Please reach out to me so I can send you these videos of the phantom braking.

When using auto pilot our car will suddenly slam on the brakes usually for no reason. Sometimes it will if there is a large vehicle in the oncoming lane. Other times it will do this if we are the only car on the road. It will also do this even more frequently at night. It does this even if emergency braking is turned off. It causes us to panic and search around for a problem. At minimum they need a way to turn this "feature" off and offer normal cruise. This system is not ready for road use. This happens multiple times every time we use the car.

My 2021 Tesla Model Y has a huge problem with phantom braking. It even occurs when I am only using cruise control. Sudden stops and slow downs. I clearly has problems with large vehicles approaching in adjacent lanes. Not only does it scare the daylights out of my passengers, but it is a major safety issue is someone is following closely behind. The answer I get from Tesla Mobile service is to keep reporting it as a "bug". The answer I get from my Tesla Service center is "what to you expect...Tesla Vision is still in Beta mode". I am selecting a date below because your form requires it, but the problem has been occurring since I took delivery in July of 2021

While on a 475 mile road trip, my vehicles emergency brake system was activated while using cruise control on more than one occasion with no visible hazard ahead of me. This caused my car to brake at speeds upward of 70 miles per hour on two lanes highways, leaving me to fear that any car behind me could easily rear end me and harm me or my children who were in the backseat. On another occasion during this same trip, the weather began to turn. Snow began to fall heavily leading to poor road conditions. My model y activated corrective steering twice at speeds of 10-20 miles/hr, both times attempting to swerve my car into the lane next to me occupied by a semi truck. These issues are unacceptable and need correcting as they pose a threat to passenger safety.

The full self-driving mode in my tesla does not react correctly to speed limit changes in small towns. I will be driving with the FSD at 65 MPH when I get to a small town and the speed limit changes to 45 and then down to 25 for residential area the cars speed does not decrease quickly enough to be at the correct speed limit by the time the car reachs the speed limit sign. Based on the speed limit laws I was taught was the car you are driving and are slowing down you must be at that limit when you reach the speed limit sign or else you can be ticketed for speeding. The Tesla FSD is not in compliance with that specific rule of the road.

This car is continually slamming on the brakes when in cruise or autopilot I have reported this to Tesla and tried to have them repair it but they say it’s normal. My 2019 didn’t hav3 this issue. One time I’d did this my wife started to chock on her gum when it slammed the brakes on so hard it dropped about 40mph in a few seconds.

Multiple times on highway car “phantom breaks” when there are no obstacles/cars in front of me. I noticed that the car seems to regularly do this at certain places the highway. For example, on one stretch I’ve had it happen multiple times going under a specific bridge when I’m in cruise control. The car seems to think the speed limit has reduced, leading me to believe the car is reading the overpass speed liMit, not the highway, and adjusting. On another highway, after a steep decline there is an incline. At the end of the decline, the car slams on the breaks as if it thinks the incline in the road is an obstacle.

I have experienced many episodes of sudden, unexpected and seemingly inappropriate strong braking. The most common circumstance is overtaking semi truck/ trailers that are slowly ascending the mountain slopes of Interstate 5 in southern Oregon. Often the trucks have their emergency flashers in use. IT self-brakes from 65 mph down to perhaps 30-35 mph and I "take over" by depressing the accelerator. It also happens frequently with oncoming traffic on 2 lane highways night or day and usually on a curve. The problem is frequent enough to avoid using cruise control on 2 lane roads and on I-5 mountain grades. It happens reliably on my way to town where an intersection has a flashing light and the approach is downhill into a right hand turn. It does not happen travelling the other direction and does not require any other traffic. For all of these, the sudden braking puts myself and others at significant risk for a rear-ender" collision. There are no lights, warnings, or ability to learn what triggered the inappropriate braking. I do not have the full self-driving option on this vehicle. A call to Tesla for service concludes with, " There are no faults with any of the hardware in the vehicle and these behaviors are a limitation of software in the system at this time". I did not take it to them to look at the car as it is 5 hours of driving plus the service time to do so.

Driving down the highway/interstate when autopilot is on and the brakes are automatically applied for no reason. This happens frequently, especially on two lane roads to the point where I am not able to use autopilot anymore of fear of the car behind me crashing into me when brakes are applied suddenly for no reason.

I have a 2021 Tesla Model Y. Washing Post reported an increase in phantom breaking recently. It's not just recent. I took delivery of my car in May 2021 and quickly learned that when in cruise control this car will randomly apply the brakes - at times going from 70's to 30's very quickly. In a simple drive from Las Cruces, NM to Albuquerque, NM with no traffic on the freeway the system will throw on the bakes while in cruise control at least 6 times. And it's repeatable. You simply cannot use cruise control on the free with any traffic for concern of the system engaging and causing an accident.

Since delivery the vehicle has experienced several "phantom braking" incidents in situations where no threat was evident, including some in which braking was initiated on clear, straight highways with no other traffic anywhere in sight. The events are aggressive and result in immediate profound loss of speed, making the threat of a collision an issue.

When using Autopilot, I experience multiple, repeatable phantom braking issues on a regular basis. While it is worse on two lane highways, I've also experienced the issues on separated freeways and interstates. The phantom braking varies from a minor throttle response to decrease speed to full emergency braking that drastically reduces the speed at a rapid pace resulting in unsafe driving conditions for occupants of my vehicle as well as those who might be following behind me. Situations that seem to trigger the phantom braking include cresting a hill with oncoming traffic, navigating a turn with oncoming traffic, a larger than average vehicle (commercial truck/tractor trailer) approaching in the opposite late, shadows cast by large trees or overpasses, and changes in pavement color - for example, transitioning from gray concrete to black asphalt.

I have experienced 3-4 occurrences of "phantom braking" while driving on the freeway with the autopilot system engaged on my Model Y. Each time, i have been traveling at 70mph+ when the automated system suddenly slammed on the brakes, causing me to decelerate by 20-40mph before I was able to override the systems by stepping on the accelerator and disconnecting the autopilot system.

Saw this article today in the Washington Post: https://www.washingtonpost.com/technology/2022/02/02/tesla-phantom-braking/ We have a 2021 Tesla Y. It does not have the Lidar technology. We have experienced this phantom braking when driving west and east across I-94 through MN and North Dakota and Montana. Sometimes it seems like it happens when we cross over a small bridge on the interstate and sometimes it happens randomly. We can't figure out what set it off. Anyway, I told my husband we should never use the auto pilot as that is when it occurs. So, we have quit using it. It is super scary when it happens!

A well known phenomenon of "phantom breaking" occurs frequently and without warning with the Traffic aware cruise control engaged. This occurs not only on 2 lane highways, but even on undivided and divided highways. On the 17 mile commute to work everyday, this will occur 5-10 times, which results in rapid, unanticipated deceleration. At the time of these deceleration events, there is no visual cause to the driver that would have resulted. Often it appears to be activated by oncoming traffic lights, lights on the side of the road at businesses, when cresting the road, and when the road naturally has a bend or swerve in the traffic pattern. These rapid deceleration events place the occupants at risk of rear end collisions and also are uncomfortable as you must immediately place your foot on the acceleration pedal, which results in a jerking movement to the occupants. Telsa needs to either employ a "dumb" cruise control or greatly improved their TACC system before continued use of their system.

On a recent trip to Minnesota when adaptive cruise control was engaged there were several ( >10) episodes when the car would suddenly decelerate for no apparent reason. On a two lane highway it might occur if a large vehicle such as a truck was oncoming in the opposite lane. On the interstate, the common scenario was traveling in the right lane going up a slight upgrade with a car passing in the left lane. Often the sudden speed reduction was 25 mph or more. On occasion even on a flat section the car might suddenly brake for no apparent reason. On one occasion this happened in the afternoon going west with the sun glinting off some shiny asphalt crack filling. No accident occurred, but if a car were following closely, sudden braking could cause a crash. Because of this erratic behavior I don't use adaptive cruise control except for short distances. This is a known Tesla problem, but it seems the company is more interested in enhancing games to be played while charging rather than attend to a major flaw.

My Tesla Model Y seems to be suffering from what is called "phantom braking". My vehicle was produced shortly after the radar was removed and Tesla went to a camera only system. My car has the lasted updates installed. It is not a Full Self Driving vehicle. Since I purchased the vehicle it has had a problem during low light or sunny conditions with suddenly braking when using the cruise control. The situation has been reported to Tesla multiple times and "bug reports" were recorded and reported to the service center. During one morning drive of about 35 minutes I reported 8 occurrences. Sometimes the vehicle will sound the emergency avoidance braking. The car will suddenly slow from 60 to 30 mph. On multiple occasions the vehicle behind me had to take evasive action to avoid rear ending me. During one of my service visits the vehicle was taken on an extended over night test drive and the technician confirmed the problem. During the other visit the service center did not even take the vehicle for a drive. in both cases Tesla said the hardware was functioning normally and this was a "normal" operating condition for the vehicle. The car does better if I am following another vehicle because it seems to be able to maintain it's depth perception better if it has that reference point. I did report to the service center that the car seems to follow closer at night, even at the max following distance setting. The vehicle also struggles with the automatic high beam headlights which the computer turns on automatically if cruise control is activated. Very often the car is slow to turn the high beams off but in other cases it will turn the high beams off and then turn them back on as another car approaches. I am flashed by other drivers on a daily basis because of this. Tesla does not seem concerned with resolving these known issues. I hope NHTSA involvement can get their attention for these safety related items.

On 2 occasions within the last month my Tesla Y experienced a radical but brief stopping response. This happened on a freeway while passing a large truck in an adjacent lane. The car suddenly slowed down and then immediately speeded back up. This happened a second time on a freeway but I am unsure of the specific circumstances. I got delivery of the car in Oct 2021 and both of these incidents happened in Jan 2022. It has only happened those 2 times.

I have experienced several instances of the phantom braking in my Tesla model Y. it primarily happens when I’m on a two-lane road and there is a large truck approaching on the opposite lane. However it will also phantom brake on a highway where there are two lanes going in one direction separated by a median with two lanes going the opposite direction. It seems to happen when it’s coming up on a slight hill, where you cannot see over the hill. The car will slam on the brakes in the middle of the freeway, which when going at speeds of 65 to 75 miles an hour when traveling with other vehicles going the same speed, it can be especially dangerous in Texas where the giant pick up trucks like to tailgate electric vehicles. In one instance the pick up truck behind me thought I was brake checking him and jamming on my brakes to be a jerk; he then “coal rolled” me, putting out a giant cloud of black smoke. This situation has made it so I am afraid to use traffic aware cruise control, which I need to be able to use on road trips. It is especially bad in the two-lane winding roads around Amarillo, Texas, but I’ve also had it do this on a much larger road that goes through Chandler, New Mexico to Colorado. I absolutely love my Tesla, but the phantom braking is concerning, and the response I’ve gotten from Tesla service is that the car adapts and will eventually learn where not to do it. I don’t know if that’s true or not, but it doesn’t seem to be getting better, and it does it at the same locations on the road. I need cruise control to be working. Another suggestion might be to have the ability to turn off traffic aware cruise control. I paid for full self driving but have not had the courage to apply to use it because of phantom braking. I would also like to see federal laws passed to address coal rolling of electric vehicles. It is extremely dangerous and it’s happening a lot in Texas.

I’m experiencing “Phantom Braking” in my Tesla Model Y. I live in a rural area where 2 lane roads (1 lane each direction) are the only roads around. Larger pick up trucks, pickups with trailers, busses, semi trucks, dump trucks, sprinter vans, and other vehicles of that size in the opposite lane trigger my vehicle, when in cruise control, to slam on its brakes. This happens when it’s sunny, cloudy, any type of weather condition. Occasionally, when in cruise control, I notice the car makes slight braking attempts, even when there is no traffic in the other lane. It’s as if it’s sensing a ghost it doesn’t want to hit… This has happened ever since we purchased the vehicle. I do not use auto pilot because I do not see the point where I live. This issue happens when using the adaptive cruise control. I have not noticed it when using auto pilot as, mention before, I rarely use that feature. I recently say articles where many other Tesla owners were having this problem so I thought I would add to the awareness of this issue. My wife does not use cruise control nor auto pilot for fear the car will slam on it’s brakes and someone might rear end us. Speed limits range from 35-55mph in my area.

The vehicle driver assist system frequently has phantom braking in situations it should not be, especially when there are vehicles behind putting us at risk for a collision due to unexpected braking behavior of the car. This happens especially in setting of 2 lane roads with oncoming traffic, and guaranteed with a truck in the vicinity. On major highways it is less so, but does still happen occasionally. On local roads even if straight and no obstruction the automatic braking without notice occurs when least expecting. Also the lane departure system disables automatically for the remainder of a drive if you veer off a lane even once and didn't take the corrective action the vehicle thinks should have happened. That's not how a safety feature should work... It should remain on regardless. As much as I do enjoy this car, these quality issues definitely make you second guess and keep a closer eye on how you drive to avoid accidents if the system decides to not work as advertised

-Tesla autopilot phantom emergency braking, multiple times makes using the autopilot useless, can't even set it to just cruise control. Yes. -Hard, unexpected, emergency braking at highway speeds from 75mph to immediate 35mph. Dangerous to passengers and other motorists due to the sudden, unexpected high deceleration speed. -Yes. Reported the problem to Tesla service center Spokane on 11/15/2021. They performed a remote investigation and told me I had used the car in a manner/location that was outside the current limitations of the software. No further action until the software system is updated sometime in the future and remotely closed the service appointment without any further input from me. - No. Phantom braking started the day I picked it up 9/24/2021 and continues to this day.

This car has had numerous phantom braking incidents. It is unusable on 2 lane roads. It breaks suddenly for trucks in the opposite lane. It can also begin to brake for cars in the opposing lane. The only remedy is to press on the accelerator to turn off the Autopilot. It also slows down periodically for shadows (for example when going thru an underpass). It was reported to Tesla service and evidently nothing can be done since it seems to be a software issue. I am unsure of that since this car no longer has the radar that previous versions of this car did have.

The Tesla adaptive cruise control has been malfunctioning for the past 12,000+ miles (since new). Yes, it is available for inspection upon request. When the cruise is set, there are a significant number of phantom breaking events, making it a real hazard for anyone following our vehicle. The breaking can happen as often as 3 times every minute, and can decelerate 10-15 mph within seconds before I am able to react and override the cruise. The vehicle has been inspected 2 times by the manufacturer and has been found to have no hardware failure. There is no warning prior to the phantom breaking. However, periodically there are warnings during the phantom breaking events in the form of alarms sounding.

Sudden braking while passing semi-trucks on a 2-lane highway while using Autopilot and Traffic-Aware Cruise Control. I made a video: https://www.youtube.com/watch?v=LW-nrsR1Bg0

The adaptive cruise control system is very dangerous due to constant "phantom braking" problems. With cruise control enabled, the car will randomly slow down, sometimes gradually and others times rapidly. Sometimes the deceleration happens when passing a large truck, or a car on the other side of the road. Sometimes it is in response to shadows on the road. Sometimes there is no discernable reason. Instances of rapid and unexpected deceleration make it likely we will be hit by another car or otherwise cause an accident. This problem is prevalent throughout all Model Y cars and detailed online. Dealers say that there is nothing wrong with the vehicle and they hope it can be fixed in the future by software. However, in the meantime, the dangerous situation exists. My vehicle has not been inspected by anyone for this purpose, at least not yet. There are no warning lamps or messages when this happens.

75 MPH on interstate with FSD 10.9. 6 separate phantom braking events over 350 miles. Very dangerous in traffic.

I was driving on the 7 mile bridge in the Florida Keys with the Adaptive cruise control set to 58 mph. There was no traffic in my lane for about a mile ahead of me. As an oncoming Semi approached me, remaining in his lane, my car applied emergency braking. I had to immediately add throttle to avoid a collision with the truck behind me. This “ Phantom braking “ has occurred on multiple occasions to me. There is no way to engage cruise control without the adaptive feature which uses cameras instead of radar on these new Teslas. I did not have this problem on my 2018 Tesla that did use radar.

When using cruise control or autopilot the vehicle will suddenly slam on the brake which almost caused an accident on multiple occasions. The lack of lasers has caused the cruise control and autopilot to become very dangerous to myself and others in road as the phantom braking it does for no reason is very powerful.

Vehicle constantly experience phantom braking. Will randomly brake for shadows, vehicles in the opposing lane, and when it feels like it. Chance for rear collision is higher due to autopilot.

The cruise control and auto pilot functions failed while driving in the rain. The car would not disengage from auto pilot and continually would engage back into auto pilot and eventually locking tires and spinning out across all lanes of the freeway. My safety and all the drivers around me are put at risk when something that dramatic occurs. The car spun out completely out of control and after doing a complete spin the car continued to spin losing all control and ended up inches from the center median and was facing oncoming traffic. Unknown- I instantly called tesla and removed my memory stick from the vehicle, they are still conducting their "investigation". Took it into the dealer and had them look into the issue. They are currently remotely working on what caused the issue with their engineers. No warning lamps or messages appeared prior to the occurence.

The cruise control and auto pilot functions failed while driving in the rain. The car would not disengage from auto pilot and continually would engage back into auto pilot and eventually locking tires and spinning out across all lanes of the freeway.

Several times now the car has done a phantom braking event where the car brakes for no reason when using adaptive cruise control on two lane highways. Mostly it's when large vehicles like a semi truck or RV passes in the other lane. Sometimes it appears to be due to shadows like overpasses or trees. The car slows down so quickly sometimes that if someone were following me it may cause a rear end collision. Most of the time the slowdown happened without warning. I have submitted a service ticket with Tesla about this but this seems to be a systemic problem on the TMC forums: https://teslamotorsclub.com/tmc/threads/phantom-braking-in-my-new-model-y.253378/#post-6301315 https://teslamotorsclub.com/tmc/threads/phantom-braking-and-active-safety-features.248184/ https://teslamotorsclub.com/tmc/threads/possible-to-deactivate-tacc-and-use-regular-dumb-cruise-control-phantom-braking-unexpected-slowdowns.235813/ https://teslamotorsclub.com/tmc/threads/27-phantom-brake-in-10-miles-how-often-should-i-press-camera-button-to-report-10-6-1-fsd.250396/

The car's adaptive cruise control system will suddenly and dangerously brake in random situations on multiple occasions. It presents a very dangerous condition should there be cars behind that can't brake in time

The car's adaptive cruise control system will suddenly and dangerously brake in random situations on multiple occasions. It presents a very dangerous condition should there be cars behind that can't brake in time

When driving on a two lane road and approaching an oncoming 18 wheeler the cruise control consistently slams on the brakes and I am concerned about the well-being of my 5 and 4 year old in the back seat. It whips them forward. I am also concerned about cars following me and getting rear ended with the force it is applying this phantom braking. I called Tesla and they said this is expected behavior and it might be fixed in a future firmware but no guarantees. I think this is an unacceptable answer regarding the safety of my family.

Traffic Aware Cruise Control is just about useless on 2 lane highways. Once enabled it is plagued by frequent decelerations for absolutely no obvious reason. What is more concerning is the application of emergency braking when meeting an oncoming truck, even on a well marked highway where the truck is centered in it’s lane. Fortunately this has not happened to me while I was being followed by a vehicle, but it is highly likely that a large truck or inattentive driver would have rear ended me in this scenario. Tesla service has looked at my car, and told me that everything was working properly, that it was a common complaint and they did not have a fix.

On Monday November 22 at around 6:15 PM CST, I was driving my model Y and had Tesla's Full Self Driving Beta software engaged. A right banked curve on a two lane road in a rural area came up with a vehicle coming around the curve the opposite direction. The Model Y slowed slightly and began making the turn properly and without cause for concern. Suddenly, about 40% of the way through the turn, the Model Y straightened the wheel and crossed over the center line into the direct path of the oncoming vehicle. I reacted as quickly as I could, trying to pull the vehicle back into the lane. I really did not have a lot of time to react, so chose to override FSD by turning the steering wheel since my hands were already on the wheel and I felt this would be the fastest way to avoid a front overlap collision with the oncoming vehicle. When I attempted to pull the vehicle back into my lane, I lost control and skidded off into a ditch and through the woods, causing significant damage to the vehicle. I was able to retrieve the dashcam footage of this incident and it is attached here. I did analyze the footage myself briefly. You can see the vehicle leave the lane, and within about 10 frames, I had already begun pulling back into the lane before losing control and skidding off the road. Since this video is recorded at about 36 FPS, this would mean I reacted within 360ms of the lane departure. I understand it is my responsibility to pay attention and maintain control of the vehicle, which I agreed to when I enrolled in FSD beta. I was paying attention, but human reaction does not get much faster than this and I am not sure how I could have otherwise avoided this incident. I am thankful this was the outcome rather than a front overlap collision with the oncoming vehicle, which would have likely resulted in bodily injury. Tesla has confirmed that FSD beta was engaged, per the attached correspondence, but insists that this incident and the resulting accident are my responsibility.

When cruise control or Autopilot systems are active, the car will often slam on the brakes and sound an alarm as if there going to be an imminent collision, even thought the lane is clear in front of the car. This happens most likely often when cresting small hills or on curves. There may be a car in coming in the opposing lane, but there is no danger as the opposing car is fully in their lane. The adapative cruise control or Autopilot system decreases the speed very quickly, often reducing the speed by 10-20mph within seconds. This causes panic for the driver and any cars behind us have to suddenly slam on their brakes, creating a dangerous situation. I own both a 2021 Tesla Model Y and a 2021 Model 3 that both have the Tesla Vision Camera based cruise/Autopilot/collision detection system. This problem has gotten worse as Tesla has released new firmware updates in recent months. Many Tesla owners are reporting that they are having the same issues recently. Tesla's response is that the systems are under development and that they will improve over time. The problem is that this is a safety issue NOW! They seem to be overly focused on developing and testing their full self driving systems that they are ignoring a huge safety flaw in their current cruise control and Autopilot systems.

I am experiencing phantom braking when using both the features listed below * Adaptive Cruise Control * Tesla Auto-Pilot I have experienced this safety issue when 1. I would be crusing on the road using either of these featuers. All of a sudden, and without warning, the car has applied brakes, even when there's no object / human in the same lane or attempting to come to the lane. 2. I'm cruising in the middle lane of a 3 lane highway, with no vehicles around. This has happened even when vehicles are following behind my car. 3. In both daylight and at night.

While driving my Tesla Model Y using cruise control, the vehicle will continuously brake suddenly for unknown reasons. In several instances, I was worried that the car following me would either hit my car or be forced to take other actions, possibly causing an accident. The system is dangerous and useless. When I contacted Tesla regarding my concern, they said something about the software program evolving…no fix available. I have had my Tesla Model Y in their service center three times and have had numerous phone conversations with them and their customer service department regarding this issue. They said they simply cannot do anything about it. Again, the cruise control system is extremely dangerous. Please require Tesla to resolve this problem immediately. Thank you.

On two occasion, our brand new Tesla model Y lurched forward from a complete stop. The first time, on 2021/10/09 at 4:36pm I was at a car wash and trying to put the car in neutral. Fiddling with the gear selector, the car jumped forward without me touching the pedals. I hit the breaks and neither the car or anyone else was injured. The second time, on 2021/10/25 at 8:10 am, my wife was dropping off the kids at school. At full stop the car lurched forward again without her touching the pedals or the speed controller. The car hit the car in front of it 3 times with force. The car as well as the two other cars in front of it got seriously damaged. My two year old son was on board, there was many middle schoolers around but thankfully no one was injured. Incidents were reported to Tesla right away who has assured us they would investigate but we have had no update since despite contacting them multiple times. They assured us they have the ability to download telemetry remotely but I am concerned that as time goes by data will no longer be available. We later got an alert on the app that the emergency braking system had been disabled at the time of the second incident. I have videos files, recorded by the car itself of both incidents as they are happening available. The body damage of the car is fully repaired but the car is otherwise available for inspection/data downloads.

I was driving on Interstate 80 in NJ this morning. I was in the middle of three lanes. In the lane to the right of me were two tractor trailers. Adaptive cruise control was engaged. For no apparent reason my vehicle suddenly braked hard, startling me and making me wonder what I might have missed in my surroundings. There was no hazard...this was frightening and a major flaw in the system that I have seen referred to as "phantom braking." It has happened to me a couple of times before but never on such a crowded roadway...I could have been rear ended. This component of the vehicle has not been subjected to a service call...the car has 5,000 miles. There was no warning.

While driving on an interstate highway (75 mph) at about 12am (little traffic) on four separate occasions, with cruise control engaged, the brakes were unexpectedly applied without warning, no forward traffic, no wildlife, no vehicles on the side of the road. Had there been a vehicle behind us, it could have resulted in a rear end collision. Several days later, on a two lane road (55 mph), cruise engaged, with oncoming large delivery/semi vehicles, again, the brakes were applied as if it was an imminent collision - which it was not. We have not seen any warning lamps, messages, warnings - however, we are new to this vehicle and not sure where we would see such a warning. After the latter event, I contacted Tesla service but was told it is an issue being looked at however there were no fixes available at this time. I have not driven with cruise control since as I am very afraid of being rear-ended.

Tesla's autopilot / adaptive cruise control / emergency braking is defective. On multiple occurrences I have had incidents where the vehicle's adaptive cruise control and automatic emergency braking systems have activated inappropriately. In one occurrence I was driving on I-17 through Phoenix in the middle lane. I was beginning to pass a pickup truck pulling a trailer (my front bumper was just behind the trailer) when the car detected this as an imminent collision and applied significant braking. I had to use the accelerator to disable the emergency braking, and this triggered a number of cars behind me having to brake as well. In a second occurrence I was driving on SR-74 westbound in phoenix between I-17 and Lake Pleasant Parkway. This is a two lane road in many sections, and at one point I had a semi truck and trailer coming towards me in the opposite lane and my car detected this as infront of me and applied emergency braking. Thankfully there was no one behind me as the vehicle reduced speed from 65 to 40 before I was able to push the accelerator and resolve the issue. There have been other incidents of it braking in ways that were unexpected and dangerous. What component or system failed or malfunctioned, and is it available for inspection upon request? Auto pilot / adaptive cruise control / automatic emergency braking How was your safety or the safety of others put at risk? See Above Has the problem been reproduced or confirmed by a dealer or independent service center? NO, but is well known among Tesla owners Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO

Have a recurring issue with phantom braking, without apparent issue, causing the car to suddenly brake (hard) without warning. (60 mph to 30 mph). This happens when using adaptive cruise control. Dealer has been contacted and their response is that this is perfectly normal, it happens to everyone, and that the car and systems are in beta. They indicate all that mechanical components are in working order and my software is up to date. Over time this may be fixed. Meanwhile, I’m concerned about being rear ended caused by my car's sudden phantom braking. This issue is prevalent in other Teslas and reports on the internet are numerous.

When traveling down a clear road with no obstructions, the Tesla will unexpectedly put the brakes on, sometimes mildly and sometimes severely when the Speed Sensitive Cruise Control OR the Autopilot is engaged. This is not Tesla full self driving, just standard cruise. This is a known problem that Tesla is aware of and has not addressed. The problem has become much more pronounced in recent software updates. This happens frequently and sometimes causes an unsafe condition causing me to not want to use this feature while driving at all.

Every time I drive on a two lane undivided highway with traffic aware cruise control or AutoPilot engaged, the car will slam on its brakes when a large vehicle is passing in the oncoming lane, even if the passing vehicle is safely passing. Phantom braking with vision only.

Adaptive Cruise Control breaks hard for no apparent reason. If there had been any cars trailing close behind I could easily be rear-ended. Happens at least once every time I turn on cruise control. On a recent longer highway trip of about 90 miles it happened three times. One time on that trip it happened while passing under a bridge, did it pick up the lower speed from the bridge above? The other times it seemed to happen for no reason. All these times our hearts dropped (2 passengers in car). Note that I do not have full self driving, so I’m talking about adaptive cruise control being the problem.

While using autopilot (adaptive cruise control) and driving on two lane highways the car will suddenly apply braking. The braking is abrupt and aggressive. The concern is being rear ended even for vehicles following at a safe distance. The abrupt braking happens randomly and more consistently when there is an oncoming car, especially around turns or hills.

The autopilot randomly applies the brakes. Sometimes it applies the brakes on a 2 lane highway when a truck or large vehicle approaches in the oncoming lane. Other times nothing is in the lane and it slams on the brakes. Other times the forward collision warning starts making noises and nothing is in front of me. I took the vehicle in for service, but of course the Tesla tech could not duplicate. Although the invoice says "autopilot will improve as firmware is released."

While driving on a two lane highway at 70mph with adaptive cruise control on, every time a semi would approach the car, the car would brake really hard with no notice. Not one car caused this issue. It was only large semis trucks or trailers.

Car is frequently emergency braking when autopilot is enaged and large trucks or semi tractor trailers merge from the right. Car will also unnecessarily and prematurely emergency brake when cars are climbing a hill. The unexpected braking has nearly caused several accidents and we have discontinued use.

When driving with Cruise Control engaged, the car repeatedly brakes VERY HARD. Sometimes the braking is when there is a car in the opposing lane and is approaching but not over the line. Sometimes the sudden hard braking occurs for no apparent reason. But on a two lane highway this occurs VERY regularly. It occurs several times an hour. This is a serious problem because if there is a car behind me the sudden hard braking may cause that car to crash into me from behind. You can submit a bug report to Tesla by pushing the right hand steering wheel button, saying "Bug Report" and then describing the report verbally while driving. This will include all sorts of driving data being sent to Tesla. I have done this dozens and dozens of times. Each time I get a message on the screen thanking me for sending in the bug report. Never once have I ever heard back from Tesla other than the instantaneous message on the screen saying that the bug report has been submitted. I believe that Tesla has had a recall for a very similar problem with the Model S and Model X with Full Self Driving. This recall was fixed almost immediately with an over-the-air software update. However my problem does not relate to Full Self Driving (which my car does not have). This relates only to cruise control. I have spoken to several other Model 3 and Model Y owners who ALL report the exact same problem. A quick search online will reveal hundreds of other similar reports for Model 3 and Model Y owners who do NOT have Full Self Driving. I believe this is a very serious safety problem and needs to be addressed immediately. Regards, Ken Maples

When placed in cruise control (which is called TACC: traffic aware cruise control), and driving on 2 lanes road, the car frequently (more than 10 times over 20 miles) slams on the brakes when incoming large vehicles on the other lane. This is generating dangerous situation with following cars being surprised for sudden (and unwarranted) braking occurs. I have a dash cam video of one such incidents

Vehicle will brake hard when approaching oncoming large trucks. This may result in a rear end collision of the following vehicle and possible chain reaction incident. The vehicle has not been inspected and is two months old. This is an ongoing issue and common with this make and model.

When driving on cruise control the car will suddenly and randomly decelerate and/or break for no reason. I have had this happen on empty two lane highways and on 4 lane highways with cars around me. It's incredibly stress full and if cars are following too close very dangerous.

Driving I5N near Delmar with auto pilot in daylight, car suddenly braked while there was no obstacle, or any other car in front of it. Luckily no one rear-ended me. Max cruise speed was set to 75 MPH, and speed suddenly dropped below 45 MPH. The maximum cruise speed I set to also automatically changed to 45 MPH as well.

When on Cruise Control or using Autopilot mode, there are frequent phantom breaking issues. On a long trip, we experienced phantom breaking consistently on the Highway both at night and during the day. These phantom breaking issues would sometime be significant and immediately drop speeds 10 miles an hour creating a danger of surprising people behind us. On a 2 lane country road, the issues are GREATLY compounded. The breaking would constantly trigger with oncoming traffic in the other lane and break VERY hard with the auto break alarm sounding. At night on a country road, it occurs with almost EVERY oncoming car. It is amazing to me that this made it through quality control because it is easily reproducible. The auto braking feature should just be turned off for country roads if this can't be fixed. At one point, I was right next to an older Model 3 on a mountain passing lane when an oncoming car was coming. The Model 3 was in the left lane closer to the 'danger' and my car phantom braked with the auto breaking alarm coming on and the model 3 just continued on, no issue. No idea if they were on cruise or auto pilot etc.

On September 26, on our first long distance trip with our just delivered (9/17/2021) Tesla Model Y, during daylight nice weather driving with Adaptive Cruise Control switched “On”, on at least 6 occasions (strait roads, freeway and non-freeway driving), the car suddenly, without any reason, violently slammed on the brakes. These events are hair raising for me and passengers, let alone for a driver behind me. If he/she does not pay attention at that very moment, the result could even be disastrous. I would never have expected such a serious safety issue with a Tesla. Suffice to say that this is absolutely unacceptable to me. When checking out the web, many people reported similar issues with their Model Y vehicle. I had the car checked-out at the Tesla Lynnwood, WA, Service Center on September 30, 2021, and when picking-up the car I was informed that no anomalies had been found. At later dates, similar emergency braking occurred without any reason, while driving with Adaptive Cruise Control. Obviously, I do not trust this Cruise Control system one bit anymore, and no longer use it. I have written a letter to Tesla (11/12/2021) requesting a time frame when a solution can be expected, but so far, I have not received any word from them. I sincerely feel that Tesla should temporarily disable this Adaptive Cruise Control feature on ALL Model Y vehicles currently on the road and those still to be delivered (to unaware new owners), until this serious safety issue has been resolved.

Repeated automatic breaking in the assisted driving mode when the road is clear and there are no other drivers or obstacles. The other day my speed was dropped from 55 to 45 mph. It was fortunate no one was behind me.

I have been having inconsistent behavior from the autopilot system. The vehicle has hit the breaks hard when no obstacle was present. I have not had this problem verified by a dealer/service center. It happens seemingly randomly. There was no warning before the breaking started.

The latest version of Autopilot has very serious phantom braking issues. It will brake hard frequently for no apparent reason. Other times it will slow down, but not braking hard, also for no apparent reason. It will also beep at me frequently when cars are approaching in the opposite lane, again for no apparent reason. In short, the latest version of AP is all but unusable and more importantly is not safe for us b/c of the phantom braking issue. Luckily no car has been close behind me when the hard braking has occurred but it certainly could be and could cause a serious accident.

Other times it will slow down, but not braking hard, also for no apparent reason. It will also beep at me frequently when cars are approaching in the opposite lane, again for no apparent reason. In short, the latest version of AP is all but unusable and more importantly is not safe for us b/c of the phantom braking issue. Luckily no car has been close behind me when the hard braking has occurred but it certainly could be and could cause a serious accident.

Driving across the country in Model Y. Passed semi in left lane, and when merging back into right hand lane vehicle applied full brakes dropping the vehicle speed from 80mph to 60mph, right in front of semi. I was forced to take over and accelerate to avoid serious rear end collision. It wasn’t just the one time, vehicle continued to perform aggressive braking actions many times. Autopilot was unusable for majority of trip. Tesla needs to make autopilot able to be disabled, and standard cruise control possible. Tesla vision is not safe, and is a major liability. It’s very clear Tesla vision is an attempt to remove radar to get around supply chain issues, at the cost of consumer safety.

I have 13987 miles on the car. 2 times in 1 month on a 2 way highway that has lane markers on the left side of the road. While using cruise control once and the second time was in auto drive mode going about 60. Hard braking with no notice, good thing no one was right behind me. I took control with no issue but this is really a safety issue. I see others reporting it maybe cars coming toward you. But in one case I was alone no on coming cars. Like I said the road has safety markers that are about 3 ft high.

Using basic Autopilot (adaptive cruise control without auto-steer), the car randomly slams on the brakes putting me at risk of being rear-ended by any vehicles following me.

Vehicle braked suddenly on the exit lane of a highway around noon time, when there was no car ahead of me. There was a large truck passing on the adjacent lane. My car gave a red color warning of imminent collision and braked hard. Fortunately, I avoided having an accident with cars following me by pressing on the gas peddle and moving ahead. Tesla service remotely reviewed and determined that at that time emergency brakes were applied because the car detected an object. Tesla said it could have been a reflection, the sun, or any number of things that could have triggered the false detection causing the vehicle to brake.

Very often when "autopilot" or "traffic aware cruise control" are activated on two lane roads (county or state highways) and there is oncoming traffic the system will alarm and brake hard as though the car is about to have a head on collision. This is a safety hazard because if anyone is following me when this happens it would be very easy to get rear-ended. This problem has been happening since I purchased the car and has been reported to Tesla 4 times along with videos of the incidents and they refuse to fix it.

This is our second Tesla, so I am familiar with the function of adaptive cruise control and autopilot. Vehicle frequently initiates hard braking events without warning or cause on the highway. I have contacted Tesla service, and they are stating that the car functions normally, and that this is normal behavior. If this is normal behavior, it is definitely unsafe. I have almost been rear ended several times.

While using Tesla Autopilot, I’m receiving significant “phantom breaking” events where the vehicle, for no apparent reason, applies the breaks, quickly and unexpectedly decelerating at highway speeds.

The car will hard brakes all the time on autopilot. I've had it occur going up slight hills, the sun being out, rounding bends, etc.

I had 2 accidents both caused by the wheel forcefully turning and not letting me take over. First incident: On 8/31/21 I was driving on the right lane of the palisades pkwy S (NJ) the car was on “autopilot” my hands where on the steering wheel. It was raining, there was no car around me for at least a few hundred feet. Suddenly the “forward collision warning” started beeping, and I felt the steering wheel is forcing itself very sharply to the left, I tried turning back to the right, but I couldn’t. Fearing that the car will end up in the lane of the opposite traffic, I slammed the breaks. The car ended up doing a 180 hitting the dividing guardrail against oncoming traffic. The car was towed to a shop where it was until oct 18 when it was ready for pickup, damage costed about 15k to repair. There was no injuries, and no other car involved. Second incident: On oct 26 A week after I picked up the car from the repair shop, I was driving on the NJ Turnpike N on the left most lane. It was raining, and the car drove over a small puddle of water. Suddenly I felt the steering wheel turning very forcefully to the right. I tried pulling back to the left, but was unable. it felt as if the steering wheel was locked, causing the car to abruptly make a hairpin curve, bypassing the next lane, and hit a car two lanes over. From the impact the car was thrown back to the left, knocked into the highway divider, the car then spun and flew all the way to the other side of the highway. This time there was another car involved. I was in the car with my wife, both of us besides being all shaken up had no injuries, it is not known to me if there was any injuries to the other driver My car was a total loss. In both instances I felt the car taking over the steering wheel and not letting me take back control. The first incident was on autopilot, second time was not. I have dash-cam footage of both incidents (can’t upload it here, will provide upon request)

Our 2021 Model Y features the new vision based cruise control system, both traffic aware cruise control and autopilot utilize this camera only system. At the time of ordering we were under the impression we were getting a much safer and mature radar based system. Upon accepting delivery at the end of May we have accumulated 9,000 miles on the car and have a had horrible experiences with the traffic aware cruise control slamming on the brakes for no apparent reason with nothing ahead or passing cars. Behavior can be 5-10mph slowdowns or in some cases FULL brake pressure which puts us in danger of being rear ended. Multiple times we have been close to rear ended. In addition the system can also produce audible beeps when cars pass however no warning or message is displayed. I want to stress this behavior is a daily occurrence day or night. We have reached out to Tesla in order to get the vehicle looked at for repairs and have a been denied even a service appointment. The vehicle was declared fine hardware wise. I documented our experiences in just one evening of driving and put together this YouTube video showing the behavior. https://www.youtube.com/watch?v=20ETPyzjc_U As referenced in the video below Tesla explains the cruise control is BETA and to be ready to take over at any moment. I take great exception to the practice Tesla is utilizing of declaring previously standard features "BETA" and making customers deal with their poor results with no accountability. We don't accept BETA seatbelts or BETA tires. This feature was enabled by default on the car upon purchase and it objectively doesn't work safely. This compliant is really an act of desperation as we simply have no other avenue to express our frustration and safety concerns for a half baked feature.

While driving using cruise control the vehicle will occasionally brake suddenly for unknown reasons. In one instance I was worried that the car following me would either hit my car or be forced to take other action possibly causing an accident. When I contacted Tesla regarding my concern they said something about the software program evolving…no fix available. The cruise control system is Dangerous. There is NO warning, you are traveling down the highway, all seems fine, and then for no apparent reason the car applies the brakes so hard that everyone in the vehicle is startled and vehicle behind you sounds their horn!

The contact owns a 2021 Tesla Model Y. The contact stated while driving at various speeds, the vehicle would experience random braking without input from the driver. The contact stated no warning lights were illuminated. The vehicle was taken to a local dealer but was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 6,450

Mileage: 6,450

The Vehicle was in FSD Beta mode and while taking a left turn the car went into the wrong lane and I was hit by another driver in the lane next to my lane. the car gave an alert 1/2 way through the turn so I tried to turn the wheel to avoid it from going into the wrong lane but the car by itself took control and forced itself into the incorrect lane creating an unsafe maneuver putting everyone involved at risk. car is severely damaged on the driver side.

Since purchasing the car less than a month ago, there have been over 100 phantom braking events while using cruise control. The vehicle will suddenly SLAM on the brakes with no apparent reason, even when there are semi trucks following closely behind. The only way I have avoided rear end accidents is by emergency presssing the accelerator. It is incredibly dangerous.

Vehicle applies brakes suddenly while cruise control is active at highway speeds, for no discernible reason. This happens extremely often and has almost caused the person following to rear end me on multiple occasions

While driving on well marked highways, the adaptive cruise control would initiate rapid and unsafe braking while using the vehicles “AutoPilot”. The braking is equivalent to a user putting full pressure on a brake pedal, losing 10-20mph by the time I am able to intervene, even if I’m ready to take over. Such rapid deceleration leaves me vulnerable to a rear collision from following drivers There is no warning, and no alarms from the vehicle. The manufacturer has no specific response, other than advising a system reset. The system reset does not solve the problem.

I was driving in cruise control at the posted speed limit of 80mph. The conditions were dry and sunny. Without warning the car braked hard and decelerated from 80mph to 69mph in less than a second. The braking was so violent, my head snapped forward and I almost lost control of the car. This 'phantom' braking occurred other times but it was less sever. The unpredictable nature of the adaptive cruise control and emergency braking has prompted me to disable these so-called safety features.

My car brakes for no apparent reason when cruis control is active of autopilot. Sometime it is about sometimes it is gradual. In one instance on the interstate at 75mph it took me down to 50 befor I could hit the accelerator petal to make it continue. This is a hazard for drivers around me. I have been in contact with tesla multiple time but they have done nothing to fix it. Lane keep assist is also an issue. When the lane keep assist is turned off in the settings it will still preform the lane keeping. This caught me off guard and caused damage to the vehicle.

I purchased the Tesla Full Self-Driving capability via subscription for my 2021 Tesla Model Y on Saturday, July 17, 2021. On Sunday, July 18, 2021 at approximately 12:40pm CT. while activating the Smart Summon feature in a private residential parking lot, the car drove itself into a tree damaging the front of the car resulting in a total cost of $1,799.32. Tesla is refusing to refund me the $200.00 for the Self-Driving subscription after their software malfunctioned. This is a dangerous feature that is available to millions of drivers. Video footage of the incident is here: https://vimeo.com/580859343 This is the description of Smart Summoned directly from Tesla’s website: https://www.tesla.com/support/autopilot#usingautopilot Smart Summon is designed to allow your car to drive to you or a location of your choosing, maneuvering around and stopping for objects as necessary. Like Summon, Smart Summon is only intended for use in private parking lots and driveways. You are still responsible for your car and must monitor it and its surroundings at all times and be within your line of sight because it may not detect all obstacles. Be especially careful around quick moving people, bicycles and cars. To use Smart Summon, open your Tesla app, tap Summon and then select the Smart Summon icon. To activate the feature, press and hold the COME TO ME button. Alternatively, tap the target icon, set the target destination of your choice by adjusting the map, and then press and hold the GO TO TARGET button. You can stop your car from driving at any time by releasing the button. Smart Summon works with your Tesla app and your phone’s GPS to operate. You must be within approximately 200 feet of your car to use. Smart Summon requires the latest version of the Tesla mobile app (3.10.0 or later). Please refer to the Owner’s Manual for additional details about this feature.

Phantom braking is a known problem with the Tesla Model Y. My adaptive cruise control has malfunctioned 2 times in 1 week. It's a very dangerous situation. Apply panic braking when the road has very little traffic and no curves. No warning signs at all. I reported the 2 incidents to Tesla. They essentially said that there was nothing they could do.

I was changing lanes on the highway and my tire flew off the vehicle. Car lost control and slammed between railing and a large truck multiple times. Airbags did not deploy. Defective vehicle!

On June, 4th, 2021 in the morning I went to Markham Park with my 13 year old daughter for the covid vaccine. We arrived and right after the shot on her we stopped our Tesla in a line where we should wait for about 15/20 minutes to see if everything was fine with my daughter. While the car was stopped in the line, I was talking to my daughter and the car started moving in the direction of the car in front of us and it hit the car many time till I turned the steering wheel to go away from there. Everything was very fast and confusing. I`m still trying to understand what happened with the car. The car was out of control and the car never tried to break or stop. I think it has stopped because I pressed the P button. I am so frightened and scared about what happened. My daughter and I, the passengers in the car in front of us and the people in the park could have been seriously injured. I opened a report at Tesla in the same day.

I WAS TRYING TO PARK THE TESLA MODEL Y AFTER FINISHING A 15-20 MINUTE TEST DRIVE ON FREEWAYS AND STREETS. I PARKED IN A PARKING LOT AT THE DEALERSHIP IN BETWEEN TWO OTHER CARS. IN ORDER TO PARK THE CAR, I WAS BRAKING TO BRING IT TO A COMPLETE STOP. AFTER THE CAR WAS POSITIONED INTO THE PARKING LOT AND JUST BEFORE STOPPING, IT ACCELERATED ALL OF A SUDDEN, SWERVED LEFT AND HIT A PLANTER IN FRONT AND ANOTHER PLANTER ON THE LEFT BEFORE COMING TO A STOP. I GOT OUT OF THE CAR AND MY FAMILY TOO AND REPORTED TO THE DEALERSHIP. I DID NOT LEAVE UNTIL TESLA FIRE AND TESLA SECURITY FOLKS CAME IN AND TOOK STOCK OF THE SITUATION. THEY FOUND THE LEFT FRONT WHEEL LOCKED IN POSITION AND HAD TO MANUALLY UNLOCK IT USING TOOLS. 3 OTHER FAMILY MEMBERS WERE IN THE CAR (INCLUDING KIDS). TESLA HAS NOT OFFERED ANY EXPLANATION FOR THE LAST 6 DAYS AS TO WHY THIS HAPPENED.

THIS IS THE 2ND TESLA MY MOM OWNED, SHE DROVE A MODEL 3 WITHOUT ANY PROBLEMS FOR MANY MONTHS. SHE PICKS UP THIS MODEL Y ON NOVEMBER 19 2020, AND DRIVES HOME FROM THE DEALER WITHOUT ISSUES. NEXT DAY NOVEMBER 20, 2020, DRIVES TO HER WORK, PULLS INTO A PARKING SPOT AND CAME TO A COMPLETE STOP. APPROX 5-10 SECONDS LATER THE CAR LURCHES FORWARD, HOPS OVER THE PARKING CURB, OVER SOME GRASS AND INTO A BRICK WALL AT FULL ACCELERATION. LUCKILY NOBODY WAS HURT, BUT SEVERE DAMAGE TO THE BUILDING AND THE CAR. THIS CASE OF UNINTENDED ACCELERATION NEEDS INVESTIGATION. MY MOM DOES NOT FEEL SAFE GETTING BACK INTO THIS MODEL Y.
