2023 TESLA MODEL 3 Forward Collision Avoidance Problems

The vehicle’s brakes did not work, automatic emergency brakes and collision warning both did not work. I pressed on the brake for about 5 seconds but the brakes did not work, resulting in a collision with the car in front. Everything is available for inspection if needed. Both my safety and the driver of the vehicle in front of me was at risk. The problem has not been confirmed yet. The vehicle is currently at a shop, waiting inspection. There were no warning lamps, messages, or symptoms.

On August 7th, 2025 at around 8 AM in the morning, my vehicles mobile phone car key was in-operable and I was unable to get in the car which led me to trouble shoot how to fix this issue with the car. Upon researching I was directed by Tesla to directly complete a soft reset of the vehicle holding down both buttons on the vehicle once I was inside, and pushing on the brake pedal. Upon completion, my vehicle booted up and I realized that all camera systems were down, my navigation systems were down, my safety features were down, my auto pilot, lane keeping assist and auto brake were down, sensors were down and I was no longer able to pre heat my battery to charge my vehicle due to issues with the navigation. I then took the vehicle to Tesla Service Center Irvine where a service advisor quoted me 2900 for a new ECU and Bolts and told me that I needed to replace my whole unit and that I was to cover the cost of the repair even though my vehicle is only 2 years of age and this failure is due to the quality control and software of the vehicle. I have been driving around a vehicle with absolutely no safety features whatsoever such as no cameras, sensors, auto braking, or full self driving due to this ECU failure and I fear for my safety and well being while driving this car.

The Tesla ran a red light on two separate occasions while in full self driving mode. The first time it went through without me being able to intervene. Given it had done it before, the second time I was able to stop it. Both times occurred at the intersection of [XXX] and [XXX] . It has not done it at other intersections.

During driving, Tesla car spontaneously stated multiple active safety features and regenerative braking were no longer available and stopped working during driving with multiple warnings appearing. Driver safety at risk during this as well as others safety due to the lack of functioning. The car was taken to Tesla service center and was explained that front lower lateral suspension links were damaged by "impact" although the car was never in an impact or accident preventing proper alignment and functioning of the car. The part has been since repaired and currently undergoing further investigation for warranty dispute.

While driving my Tesla equipped with Autopilot/Traffic-Aware Cruise Control, I experienced an unexpected and abrupt braking event. A vehicle had entered the center turn lane and had already cleared my lane, posing no obstruction to my path. Despite this, my Tesla suddenly applied the brakes without warning, causing a rapid deceleration that could have led to a rear-end collision had another vehicle been following closely. There were no visible hazards, warning messages, or alerts prior to the braking. The incident occurred in clear daylight conditions on a dry road, and the vehicle in the center turn lane was stationary or turning away from my lane. This appears to be a case of phantom braking, possibly due to misclassification of the adjacent vehicle or overcautious object detection by the vehicle’s Advanced Driver Assistance Systems (ADAS). This issue has occurred more than once in similar scenarios, and I believe it poses a serious safety risk. I have not yet had the issue inspected by Tesla or a service center, but I am submitting this report to raise awareness and request investigation into the reliability of Tesla’s braking logic in these situations.

On [XXX], my 2023 Tesla Model 3 (VIN: [XXX] ) suddenly accelerated on its own and the brakes failed to respond despite repeated pressing. To avoid hitting other vehicles, I turned into a property driveway and struck a tree. The airbags deployed. This was a case of sudden unintended acceleration combined with complete brake failure, creating a serious safety hazard. Forward Collision Warning also did not prevent the impact. A police report was filed by the Dekalb County Police Department, GA, USA (Report #[XXX], Case #[XXX]), which specifically documented brake failure as the cause of the accident. The report also notes that the driver was injured by the airbag and that the vehicle had to be towed from the scene. A copy of the police report can be provided upon request.

Autopilot (adaptive cruise control) will freak out and slam on the brakes when a motorcycle passes by splitting lanes. This is a serious safety issue as cars and motorcycles behind me may not be able to react in time and cause a rear end collision or into the wall or vehicles next to them. It is impossible to override the braking with the accelerator as it will be too late by the time the car accelerates. Flooring the accelerator is also not a safe option.

My Tesla Model 3 disengaged cruise control while going 68 mph and braked hard for no apparent reason. I was driving northbound on I-405 at 3:45 a.m. going to LAX airport in the number 3 or 4 of six or seven lanes. Cruise control had been activated for at least 10 minutes before the incident at a speed of 68 mph. There was no traffic within half a mile before or after me due to the time of day. Neither my left or right foot were near either the brake or acceleration pedal, nor were they in motion. Both hands were on the steering wheel and no control was being activated. The only noticeable environmental condition is that the road surface had just changed from a dark gray asphalt to a bright white new concrete roadway. No emergency braking alert was seen or heard, so I do not think it was a false collision detection, and there was no car within a half mile. However, I do believe the severity of braking could have caused an accident if there had been someone behind me. Tesla Model 3 Software Version was v12 (2025.20.6 046c4575d120).

The contact rented a 2023 Tesla Model 3. The contact stated that while driving at 55 MPH in the rain, a vehicle in front of him abruptly slowed down. The contact depressed the brake pedal, but the vehicle jerked to the side. The contact stated that the emergency braking system unexpectedly activated ("slams on") while he was driving due to the Automatic Emergency Braking (AEB) system falsely detecting a potential collision. There were large rocks in the roadway, and there was no traction, causing him to crash into an embankment. The driver's side airbag did not deploy. The other airbags in the vehicle had deployed. The contact sustained a fractured rib, and medical attention was provided at the hospital. The vehicle was towed to a towing company. There were no reported fires. A police report was filed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, where an unknown diagnosis was completed. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was unknown.

Description of Problem: While driving under normal highway conditions on July 2, 2025, my Tesla suddenly and violently phantom braked — meaning it rapidly and without cause applied the brakes forcefully. There were no obstacles, vehicles, or hazards present. The sudden deceleration caused a severe flare-up of a recent cervical disc replacement surgery I had undergone. I experienced extreme neck and spinal pain and had to seek emergency medical attention. I am now under medical supervision, on pain medication, and unable to work. I contacted Tesla requesting the logs from the incident and have received no response. I’m deeply concerned about the safety of this vehicle and the lack of accountability for this known and previously investigated issue. I am in the process of retaining legal counsel and intend to pursue this further as a product liability and injury case.

While driving with the Adaptive Cruise Control enabled, on California highway 5 on Aug 28, 2023, the vehicle applied the brakes very aggressively and suddenly, shy of making a complete stop, without any object or shadow requiring it to do so - known as the "Phantom Breaking". It was so dangerous that if it was a weekend with many cars behind me, I would've been violently rear-ended and perhaps not lived to report this incident. This happened twice in two hours, to the point that I have never engaged the cruise system again. The Adaptive Cruise Control (ACC) system (which is part of the Auto Pilot system) on this vehicle is dangerous and should be avoided. I wish the vehicle had the [old fashioned] non-adaptive cruise control but it doesn't. Answering the questions: Nothing failed but the ACC clearly malfunctioned since there was no object, shadow, road animal, change in asphalt color, etc. to cause it to abruptly break. It was a clear sunny day. Any accident at such highway speed could've been deadly to multiple drivers on the road. When I informed the dealer, they "verbally" acknowledged and informed me of the term "Phantom Breaking" that they had heard of the problem being reported by others but nothing to worry about and they didn't inspect the vehicle. There we no warning lamps, messages or symptoms prior to the problem. Again, this issue happened twice within a two hour period and I have not used the ACC system again. My spouse was with me in the car in both cases and witnessed the scary situation.

Curvature Assist feature agressively brakes while driving at highway speeds. This is supposed to slow down for curves, but frequently intervenes for straight, clearly marked lanes. Feature cannot be turned off. Drivers behind me have gotten agitated several times for the sudden, harsh braking, and I do not feel comfortable driving this car.

I was traveling at highway speeds on a highway with no vehicles or other obstacles in front of me. I had adaptive cruise control on. Then, the emergency brakes deployed for no reason (so called “phantom braking”), decelerating the car quickly. I turned off adaptive cruise control as fast as I could and nothing bad happened. But the situation was dangerous, as if a car was close behind me it could have rear ended my vehicle.

But the situation was dangerous, as if a car was close behind me it could have rear ended my vehicle.

The full self driving is very dangerous. I had several events that put me in danger. Like, going to the wrong lane. Going to the wrong way. Changing lanes that almost hit a car good thing I took over right away. It made the other car upset and honk at me.

Software updates caused failure notifications (seat restraint system) and disabled cameras/emergency brakes, happened immediately right after software updates. All hardware performed and properly functioned before the software updates. 1. First failure noticed on the begin of March 2024, component affected : " Rear center safety restraint system fault". Second failure noticed on [XXX] component affected: " Autopilot cameras unavailable", "Automatic emergency braking is unavailable" 2. I feel extremely unsafe now when using the vehicle with failure notification of the car's components, especially while driving my children to school. I am unsure if the system failure that could causes accidents and put my kids at risk or danger. 3. First issue was notified Tesla representative immediately right after the software update (happened over night). They scheduled an appointment, but I saw a charge bill that I have to approve before taking the car in for an inspection. It happened when my car is just out of warranty. I called Tesla dealership in Buena Park, CA to discuss about my safety concerns and got told it might be just a software glitch and I should be ok to drive. (??). Second issue was also notified Tesla and got a schedule for an inspection/service on December 10th, 2024, and again with an approval of $650 that I might got charged for ahead of the service ???? (Why do I get charged for something that wasn't my false until Tesla pushed a bad software to make us pay for their bad scripts?) 4. There was no failure notification "at all" before the last 2 or 3 software updates. Tesla offered some kind of 1 month free FSD then software updates to remove the FSD then everything started to fall apart. I am very concerned with Tesla software updates now and failures it might cause that put our family at risk because of their bad scripts or batches.

If a Tesla software update fails it causes an APB version mismatch causing all safety features to become disabled until you schedule service for repairs. It is not covered outside of warranty even though it’s an issue caused by their update. If you google APB Version Mismatch, a lot of people have experienced it. Out of warranty repair is $2-3k for a computer replacement even though it was working fine before the update.

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to brake, the system did not function properly, suggesting a potential mechanical or software defect in the braking and/or safety alert systems. Aftermath: •My vehicle sustained considerable damage. •I now feel unsafe driving the vehicle, particularly on highways, as I am concerned the brake failure could recur. Request for Investigation: Given the severity of this issue, I am seeking an investigation to determine: 1.Whether there is a defect in Tesla Model 3 braking systems that could result in brake failure under normal driving conditions. 2.If there is an issue with the vehicle’s safety features failing to activate appropriately. This incident has raised significant concerns regarding my safety and that of other drivers, especially given the car’s relatively new condition and low mileage. I would appreciate a prompt investigation into these safety concerns.

The system failed to detect the driver having a seizure and had no way for the passenger to break the vehicle. People in the vehicle and Others were put at the risk of a seizing person accelerating in a car that could not be prevented by the car or by the passenger. No dealer/service center has confirmed the issues. The vehicle is currently being inspected by police. No known warning signs/messages before the incident.

With the TACC system activated when traveling on a 2-lane road with a right-hand curve, if there is a semi-truck in the opposing lane, the emergency braking engages with a hard brake application. It can be overridden with accelerator pedal, but it endangers the car from collision with a following vehicle. There have been multiple incidents. I attempted to report the condition to Tesla customer support.

When traveling on an interstate highway with a speed limit of 65 mph, with navigation system operating and with TACC engaged, the system sometimes resets the maximum speed to that of the speed limit of the exit ramp (usually 40 mph) when I am NOT exiting the highway. This results in rapid deceleration significantly below the prevailing highway speed with the potential of causing a rear end collision from following traffic. This is consistent some certain exit ramps along I-93 in NH, and is prevalent when traveling in the right traffic lane.

The contact owns a 2023 Tesla Model 3. The contact stated that while entering a parking lot, the brake pedal failed to respond, the driver was unable to control the steering wheel and crashed into a Ford vehicle and a tree. The air bags deployed, and the vehicle stopped shortly after. The forward collision emergency braking system failed to engage. There were no warning lights illuminated. The vehicle was towed to a tow lot. A police report was filed. There was no reported fire. The contact sustained injuries to the neck and shoulder and had bruises. Medical attention was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 12,166.

While using standard cruise control (without autosteer), car sporadically & aggressively brakes for no reason with no obstruction or cars ahead and while at highway speeds. With cars close behind, a serious, life-threatening accident could've occurred. Can not determine how to recreate issue on demand. This is a known issue with Teslas that has not been addressed by Tesla. I have not reported this issue to Tesla.

Since I purchased my car in July 2023, I’ve had multiple false forward collision warning resulting in my insurance premium increasing by sizeable amounts and has caused me undue stress. I’ve reported this problem to Tesla but to no avail. Today 8/9/2024, between 5:17 and 5:21 pm, while driving my cars forward collision warning was activated while no vehicle was in front of my but instead to a parked car on the pavement. This has happened multiple times and Tesla denies being aware of any issues.

The contact owns a 2023 Tesla Model 3. The contact stated while driving at various speeds with the Adaptive Cruise Control or ADAS Self Driving feature activated, the vehicle would independently decelerate without warning. During the failure, there were no other vehicles or objects nearby. The Service Center was notified of the failure through the Tesla App. The contact was informed that since a time stamp could not be provided for each failure, the Technician could not determine the cause of the failure. The manufacturer was not yet made aware of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 28,000.

On [XXX] around [XXX], my daughter drove her Tesla Model 3 on [XXX] from school. Two strange/scary accidents happened to two different Tesla cars (Model 3 and Y). It was raining with low/medium visibility. One of the cars was driven by my daughter, and luckily, both drivers were safe with very minor injuries. The cars had significant damage but were drivable, and there were no airbags out. These two accidents occurred within 3 to 5 minutes at the “SAME LOCATION.” When I asked them what happened, my daughter and other Model Y drivers described a sudden loss of control, with their cars spinning and becoming unresponsive to steering and braking. They then hit the guardrail on the center line. I checked the video recordings of our car multiple times; no vehicle-to-vehicle collision was involved. I also checked the road to see if there was any oil spillage, but the lane was clean. She didn't use Auto Pilot, FSD, and Cruse Control. The office recorded it as Hydro Plane in his report, but my concern was incidents that happened only to Teslas. Also, when I posted this incident on a Tesla WhatsApp group, multiple Tesla owners reported that they had a similar issue when it was raining. It seems like Sensors malfunctioning in the rain. Also, my daughter was driving below the posted speed (68/70), and she gave a written note to the officer too, but the officer recorded it as 70/70. I need to check that in the Wake County traffic court. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was in cruise control, and cruise control did not deactivate causing the vehicle to propel into a building, causing airbag deployment. Safety sensors of car failed to recognize building, other vehicles, and obstructions as required.

On [XXX], I was driving my Tesla model 3 from California to my new home in Idaho as part of my move there. During the day, I had 6 or 7 situations where the car would suddenly go into full regenerative braking, or outright apply the brakes for no apparent reason. Most of these events took place of freeways at freeways speeds, or on highways (not freeways) at the local speed limit. Every situation was when I had supervised self drive or traffic aware cruise control enabled. These situations were extremely startling and in my opinion potentially dangerous. I don't want to imagine what might have happened if one of these "phantom braking" events had occurred with a heavy 18 wheeler behind me in traffic.

Tesla Motors has two self-driving features, a mode they call enhanced autopilot and Full Self-Driving. Enhanced Autopilot is used primarily on freeways, and allows the car to switch lanes without driver's assistance, while maintaining the speed of traffic. Full Self Driving is a separate system in and of itself that relies on far more sensors, and is far more complex, as it needs to be in order to handle all the nuances of allowing a car to drive itself on and around city streets. During the month of April ,Tesla previewed the supposed improvements in its full self driving mode by releasing it to everyone for free for that month. I was exiting the [XXX] freeway in Los Angeles, utilizing the enhanced autopilot feature to navigate myself to my destination. At this exit, the car makes a right on [XXX], drives down about 500 feet and then makes another right so that you're briefly traveling underneath the freeway from you'd just exited. As the car made that second right, while on what should have full self-driving mode, the car failed to navigate the angle of that turn and ran right into a steep curb at a fairly fast speed, destroying the right drive train, the right tire, the entire front bumper, and the cars wheel chassis and suspension system all still have to be fixed. I believe the malfunction was caused by the car failing to properly switch between enhanced autopilot and full self-driving if they utilize GPS to make that determination, because it felt almost as if the car was trying to switch into the lane to the right (which didnt exist there was the curb there) and not like it was attempting to negotiate or preparing to make a wider turn maneuver. I don't believe it even decelerated as it hit the curb. I broke my toe but otherwise am all right. Tesla won't honor their warranty and is threatening to repo the car they won't fix.

Full self drive FSD took car in opposite road direction, sudden lane changes, almost crash in upcoming traffic. Sudden stops in middle in road. FSD autopilot very dangerous driving that could cost crash. I can’t trust FSD

The contact owns a 2023 Tesla Model 3. The contact stated while driving approximately 72 MPH with the cruise control activated, the vehicle abruptly decelerated and nearly came to a complete stop. During the failure, there were no other vehicles or objects nearby. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 6,730. The contact stated the primary concern is that unexpected emergency braking for no apparent reason on our 2023 Tesla Model 3 was dangerous. The dealer indicated that their review of the data for the approximate date and time did not show anything and cancelled the appointment.

when I was driving my Tesla Model 3 with FSD exiting [XXX] , the FSD directed me to a wrong routing. I corrected the direction by taking over the FSD, the car then lost its full braking system. I was not aware of it until my car slipped backward at a stop and hit a car behind me. The other driver is good enough to let me go, but my Tesla back bumper was damaged. When I got home and read the message on the screen, I was told that the braking hold was disabled, autopilot was disabled, braking charge was disabled, and wheel alignment was disabled, and more. I contacted Tesla and make an appointment half a month later. I was also told that the Tesla recommends to have alignment adjusted every 6000 miles or every 6 months- while I was not aware of this, I thought Tesla is maintenance free. This was what I told Tesla representative then: If this disfunction is safety related, it should be mandatory, not recommended! I feel I was lucky that I only have a small accident, it could be worse. I just dropped my car to Tesla for repair yesterday, the estimated costs was originally $275, then it went up to ~$1500, then ~$1800, When I was talking to a representative, the costs increased to $2167 in a few minutes! I asked why the prices go up, they said the previous prices are mistakes, and if I don't want to pay, I can drive my car home! I believe this happens to many other Tesla users as well, it needs to be addressed before more accidents and damages. The fragile safety operation and the way Tesla treat its customer are not acceptable, at least to my case. Thanks for your attention, if you need more information about my report, or have any question, please feel free to contact me.

1. My 90 year-old mother-in law got trapped inside the car in very bad weather because my phone key wouldn't open the door after I got out and walked her elderly friend to the door of her house about 20 feet away, and then walked back to the Tesla. I've been able to reproduce the problem repeatedly, of course without my mother-in-law in the car. 2. Several near-misses because, unlike most other cars, the Tesla's blind-spot warning system, and many other basic control functions such as adjusting the windshield wipers, opening the glove compartment, etc, require you to take your eyes off the road. For example changing lanes requires you to look away from the lane you're about to move into to check the blind spot display on the touch screen. 3. Several near misses because easing up on the accelerator slows down the car forcefully 98% of the time, but does nothing 2% of the time. Specifically, accidentally flicking down on the right-hand control stick, which turns on the windshield wipers in most cars, activates cruise control and gives minimal feedback to the driver that cruise control has indeed been activated. In this circumstance, easing up on the accelerator pedal doesn't slow down the car at all. This is very frightening and unexpected and could easily cause an accident.

When using cruise control, my 2023 Tesla Model 3 will aggressively brake without warning or apparent cause. The braking is near maximal - as though the vehicle is attempting to prevent an imminent collision. This defect poses a hazard to occupants of vehicles behind mine as well as myself and my passengers as sudden braking could cause a rear-end collision and cascading loss of control. Inclement weather would have exacerbated the problem. This problem is documented. From my brief research it appears Phantom Braking has been the subject of a NHTSA investigation previously but for prior model years. The issue persists. When I questioned Tesla Service regarding this life and limb threatening problem their staff was aware and well versed at requesting the customer report the issue as though it were a minor software glitch. This is a significantly more serious problem necessitating an appropriate response.

I was driving behind someone when a suv came over from left lane into the right lane in front of the cars that were in Front of me and made a sudden turn into a business. I was already applying the brake and was the 3 second rule behind the car in front of me, however the car did not stop as I slammed on the brakes as hard as I could. There have been other times that the car will automatically slammed brakes on because it feels that it need to…when it’s not necessary at all. But the other day when I needed the brakes to help me stop abruptly…they failed to do so. I hit the car in front of me and was cited as well. If I had been going faster..this could have been way worse. This definitely needs to be evaluated on Teslas. I have a dahcam video that I’m unable to upload.

The adaptive cruise control of the Tesla Model 3, like other Tesla models, rely on the cameras for determining speed. While driving on the freeway the Tesla Model 3 began to abruptly break almost causing a car to rear-end me. This has occurred multiple times since the full self driving was released to everyone. I discovered that the software reads the freeway's "Minimum Speed Limit" signs as the maximum speed limit. I reached out to Tesla and was told that there would be a firmware up-date but one has not come out since.

Constant lane change while driving has gotten out of control. A couple of instance the vehicle has changed lanes without manual manipulation. This is getting out of hand and has certainly put risks on my family while operating vehicle.

The car phantom brakes constantly (at least every 10 miles) when using cruise control. You will be driving highway speed and the car will slam on the brakes for no reason,, making the cruise control dangerous and unusable

Driving normally down I-5, no other cars nearby and system suddenly phantom brakes. I am lucky no other cars were behind me as it may have well caused an accident. There were no other cars in front of me within at least 1 mile.

Back in February my Tesla Model 3 started acting up Emergency Brake was disabled, automatic vehicle hold was disabled, and traction control was disabled all issues I reported to the company app with photo. This problem stated when a software update happened after the Tesla app requested it.

As I was approaching my off ramp (which has a very tight turn), my automatic brakes failed which caused me to slam onto the brakes, and skid into one of the off ramp signs. All 3 of my children were in the back, the back driver side window shattered, I lost my driver side mirror, and there was damage done to the back door and wheel well (all on the driver's side). Although the damage looked minimal, no one was willing to work on the vehicle and I was strongly encouraged by my insurance company to claim it as a total loss. Granted, I had this vehicle for approximately 2 months, and had put at least $4,000 into it.

I decided to take my first road trip in the new Telsa Model 3. The trip was from Seattle to Portland down [XXX] which is a pretty straight and easy road. Because of this I decided to use the Autopilot feature (I purchased the FSD package) to help take the stress out of driving. (Note, this is my first Electric Vehicle AND even my first vehicle with a screen, so I stayed very aware and present the whole time driving with hands on wheel). After a while of driving I noticed the 'Arrow' icon on the maps, which indicates my car, wasn't centered on the road and was in fact about quarter to half an inch to the right of the road. I didn't think much of it as I've seen my Google maps do this before and after a little bit it readjust and fixes it. As the car was driving, it performed a SUDDEN deceleration and then put on the blinkers to turn left (which I'm on the interstate so there was no left turn). What I noticed was that because the icon on the map wasn't centered on the road, it thought I was off the side of it. When it came up to a side street, it then thought I was on the side street. Thus it rapidly slowed me down to the side street speed limit (35 mph vs the 70 on the interstate), and then thought it needed to turn left to get on to an on-ramp to get me back on the interstate highway. Luckily I was able to catch it in time, but I had to fight with the blinkers for almost a full minute to get them to turn off. After this happened again several more miles down the road, I decided to manually drive the rest of the way. Once I got to a charging station and powered the car off and on, the icon then was centered on the road again. I have noticed a few times since, that it 'gets confused' on what road I'm on and it is concerning that this has a lot of control over the car. It would be great to have a manual way to tell the map that I am currently on which road so it can then note that.

The Autopilot feature of my Tesla Model 3 was safe and effective prior to the update mandated by NHTSA. With the recent update, I now receive multiple warnings during my drive on a daily basis for checking my mirrors or adjusting the radio. These are loud and startling. This update was completely unnecessary and counterproductive to my safety. I'm sure some Tesla drivers drive recklessly, but it makes just as much sense to require ICE vehicle manufacturers to install hardware/software to prevent drivers from doing donuts. Please reconsider the "recall" you mandated of Tesla. It was unhelpful. Respectfully, [XXX] Palmdale, CA INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Jan. 1, 2024 at around 2:19-2:20PM, the vehicle in front of me made a sudden brake causing my vehicle to trigger the Automatic Emergency Brake. My foot was on the brake pedal as well, I even floored the pedal to make my car stop right away but it continued anyway, the pedal felt so loose/soft. My car almost made a full stop but when the vehicle in front of me started moving, the car started to somehow accelerate, I was confused as to why the car was moving when my foot was firmly pushing the brake. This unexpected move caused me to rear-end the vehicle in front when they abruptly stopped for the second time. My thought is since the car in front moved, the Tesla thought the vehicle in front was no longer a threat and stopped applying the brake to make a full stop. I watched a lot of AEB videos online. 1. Automatic Emergency Brake - malfunctioned, maybe, the car log has it but I took a photo that AEB was in progress during the incident 2. My experience is similar to a car without a brake - no matter how hard I pushed the brake pedal, the car didn't stop. It's frightening because I'm out of control over the situation. 3/4. My car was already repaired but I haven't taken it to a Tesla Service Center to inspect the system - the manual brake is working though 5. There were chimes and screen notifications that an Automatic Emergency Brake was in progress. I can upload the dashcam recording if you need it.

I am writing to report several safety issues that I have experienced with my Tesla Model 3. These issues pose a significant risk to my safety and the safety of other road users. I kindly request that you investigate these matters thoroughly and take appropriate action to address them. 1. Steering Wheel Failure: On three separate occasions, the steering wheel of my Tesla Model 3 suddenly stopped working. Two of these incidents occurred while driving on the highway, which made it extremely difficult for me to maintain control of the vehicle. This sudden loss of steering functionality is a serious safety concern and could potentially lead to accidents and injuries. 2. False Forward Collision Warnings: The car's forward collision warning system has been providing false warnings, which has had a negative impact on my insurance premiums. Despite the fact that my insurance company is aware of the issue and acknowledges that it is a system failure, they have been automatically increasing my insurance rates on the leased vehicle. This has resulted in a significant financial burden, with my insurance premium increasing from $120 to almost $400 per month. Furthermore, I have been informed that next month, my premium will be raised to $600. I would like to emphasize that I have a clean driving record with no previous accidents or traffic violations. 3. Slow Charging Speed: Another issue I have encountered is the extremely slow charging speed of the vehicle. Despite the fact that the Tesla Model 3 is rated at 160 kW/h, it consistently charges at a maximum rate of 50 kW/h, regardless of the charging location or time. This significantly limits the usability. Took the vehicle to the Tesla service center twice. However, they said that they have been unable to replicate the steering wheel failure which would be crazy if they could replicate it every time the car is driven. and they have dismissed the slow charging speed as a normal variation and it's not. Disregarding safety!

Repeated "phantom braking". With cruise control engaged and zero traffic in front of the vehicle, false readings on the collision detection system will cause strong, sudden, and unpredictable braking. Highly unsafe particularly in conditions where there is traffic behind the vehicle. In my first 900 miles of driving the vehicle there have been 20-25 of such incidents. When triggered, breaking force is strong and deceleration is sudden.

Driving down the highway on a clear day with nothing in front of me, with adaptive cruise control turned on, the car suddenly started braking as if it was in full regen braking. I had to hit the accelerator pedal to override the braking.

Recent recall update makes auto pilot more dangerous and distracting. I am getting alerts while my hands are on the steering wheel and paying attention to the road, which then causes me to take my eyes off the road to see the alert. Which I then get kicked out of autopilot. Was using autopilot and got an alert the max speed was reduced due to road conditions and when I looked at the alert got another alert to pay attention to the road, then was immediately kicked out of autopilot. This is extremely dangerous especially if road conditions are deteriorating and to have to constantly be looking at all the new and frequent alert. The recent recall has made me constantly have to take my eyes off the road. I can even check my side view mirrors without getting a pay attention alert.

The most current "safety" recall software 2023.44.30 which made the autopilot more alert to the driver has made the car less safe. Before the update, autopilot would work as intended and kept the car safe in the lane. Now, even when doing everything correctly, I get nothing but alerts which takes my attention away from the road. The car was safer before the mandatory government update. Honestly not surprised that NHTSA made the car less safe. Let Tesla do what's best for their cars, they had it working great before you got involved. Thanks.

Subject: Concerns Over NHTSA-Forced Changes to Tesla Model 3 Autopilot I am a Tesla Model 3 owner writing to express concerns about recent autopilot updates, seemingly implemented following NHTSA directives. These updates have significantly altered the system's operation, leading to potential safety risks. Previously, the autopilot required minimal, intuitive steering interaction. However, the new update, presumably in response to NHTSA's safety requirements, demands frequent and forceful steering inputs. This has caused abrupt and frequent accidental autopilot disengagements, a stark contrast to my earlier, safer experiences. It is extremely dangerous when it is not clear to the driver that the system has been disengaged and the nags from the system frequently cause accidental disengagements that don't always get noticed by the driver who is more focused on paying attention to the road than the screen. The heightened sensitivity of the system is not only inconvenient but hazardous. The need for constant, sometimes aggressive adjustments is distracting and can result in unpredictable vehicle behavior. Ironically, a system designed for safety is now a source of danger and stress. In heavy traffic or on highways, the risk of sudden autopilot disengagement has increased, diverting my attention from driving conditions to maintaining system engagement. This is contrary to the autopilot's intended purpose. I urge the NHTSA to reevaluate these changes. It appears the effort to enhance driver engagement has compromised the autopilot's operational safety. Modifications are essential to prevent potential accidents and ensure the system aids in driving safety, rather than detracting from it. Thank you for your attention to this critical issue. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Autopilot now requires so much force to confirm you have your hands on the wheel it’s disengages causing rapid deceleration and steering into the other lane or shoulder. Also requires confirmation at times when the driver should be looking at mirrors when passing etc instead of watching the display.

Autosteer was engaged while approaching Weatherford, OK on I40 - Sporadically, the vehicle slammed on the brakes, even though nothing was in front of me, and nothing was behind. The vehicle dropped in speed by almost 20 mph.

Summary: FSD malfunctioned, failed to disengage, causing loss of steering control, thus causing car to steer into wrong lane and resulting in an accident. Tesla Service Center refused to inspect unless car is fixed. Car was sent to Crash Champions ( autobody shop) and was quoted $35k to fix. Car was deemed as totaled by Tesla insurance. No response from [email protected] I suspect that the latest FSD software update has caused my car to lose control. Time of incident: 19:28 pm Location : [XXX] , [XXX] Entering from [XXX] . Weather condition: Clear night, well lit. Low traffic. What happened:
 My car has been driving in FSD on Lawrence Expressway and it was doing everything correctly. Approaching that upcoming tight bend, the FSD slowed down the car, and I took over by steering the steering wheel to the right to deactivate FSD and taking the tight turn, right before the white rows of triangles on the street. At this moment, the steering wheel forcibly turned to the opposite direction (i.e. left). I tried to correct the steering wheel by turning right even more, but the steering wheel wasn’t responding to my input for a split second. At this moment, my car is now on the wrong lane of Wildwood Ave and my car finally responded to my steering input. I had to swerve in the opposite direction to avoid the incoming traffic and ended up brushing against an SUV, followed by an impact on the curb, before finally slowing down. Seeing that there was incoming traffic from the back, I drove down to a residential street to park my car for safety reason. The SUV driver called the police to handle the situation, we had our information and testimonies recorded down. I have already followed the safe practices of driving with FSD according to the manual, but in this situation, I am not certain which technology is responsible for causing my car to override my manual steering input. This led to me to question the driver safety systems in this car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

When using Cruise control the car will brake suddenly even when there is no obstacle in front. This happens often. The phantom braking can be dangerous if someone is following at freeway speeds and not expecting the car ahead to brake. Also, when using cruise control the windshield wipers are automatically placed on auto. The windshield wipers will then go on and off as the sunlight changes, when no precipitation is evident. We often have to pause cruise control because the windshield wipers will not stop.

Vehicle will repeatedly aggressively brake while using “Enhanced Autopilot”, posing a danger to any cars behind. Complaints given to Tesla have been unresolved.

Adaptive cruise control falsely decelerated on dozens of occasions during a single 500 mile road trip. Sudden braking in the vicinity of other vehicles may cause a crash. Tesla's service technician stated "no hardware related faults were found" and "potential incorrect object detections leading to slowdowns may occur".

Random phantom breaking when using cruise control at high speeds. Goes from 70-40 mph and always worried someone is going to rear end me when my car automatically rapidly slows down for no reason. Huge hazard and risk!

Driving North/East on Highway 87 at 1215pm, kind of into the sun (Sun was to the right of us), the car would not maintain cruise control without constantly applying the brakes forcefully. No cars in the immediate vicinity during the event, though there were other cars on the highway at the time. Returning south on the same road, about an hour later, no issues whatsoever.

As part of transitioning from radar to a camera based system (this affects model years '22 onward), Tesla, has "temporarily" disabled key features such as lane departure, blind spot alerts and emergency braking. Though disabled, these features are still selectable (not greyed out) when the user chooses safety options. These features, which are available on most modern cars, have been disabled for many months with no committed date to restore functionality ... this poses a major safety risk. This should impact Tesla's NHTSA safety rating which will pressure the company to re-enable these basic safety features ASAP. Thank you.

Will Randomly slam on the brakes saying that there is something in front of cars on the highway. This has caused me to almost get into a few accidents suddenly slamming on the breaks at 75 mph. It has happened numerous times and the car feels unsafe to drive. One example it slammed on the brakes in front of an 18 wheeler causing it to almost hit me but I had to slam on the gas very rapidly. There is usually a warning light on about parking break not working when these happen.

On 2 separate occasions, the cruise control set to 80 and suddenly decelerates. Very scary. Term being used in Tesla chat rooms is 'phantom breaking'.

Going down secondary road with cruise control on at 42 mph ; no auto steer just plain cruise control. The car all the sudden slams on the brakes for no reason causing the car behind to slam on brakes and almost causing a accident. This needs to be addressed or the cruise control disabled until they fix the issue.

Tesla Model 3 Policy #: [XXX] Claim Number: [XXX] I hope this email finds you well. I am writing to report an incident involving my Tesla Model 3 (Blue) and to initiate the process for an insurance claim. The incident occurred on [XXX], at approximately 2:15 PM. My fiancée was the driver of the vehicle at the time of the incident. Incident Details: - Date: [XXX] - Time: Approximately [XXX] - Vehicle: Tesla Model 3 (Blue) Location: The incident took place on the freeway merge from [XXX], where it merges onto [XXX]. Heading home. Circumstances: My fiancée was operating the vehicle in Autopilot mode while maintaining her hands securely on the steering wheel. As she approached the freeway merge from ramp [XXX], heading onto [XXX], she experienced an unexpected jolt. Despite her continuous control of the steering wheel, the Autopilot system seemed to be accelerating without her input. Simultaneously, my fiancée felt a sudden tire malfunction, which resulted in a significant loss of control over the vehicle. Despite her best efforts to maintain the car's position within the lane, the Tesla Model 3 veered off the freeway and entered the adjacent Ravine area. Impact and Airbags: Upon entering the Ravine area, the vehicle experienced a collision. multiple plants/highbrush/uneven terrain as well as having to maneuver around 2 large palm trees which resulted damage to side mirror. Notably, none of the vehicle's airbags were deployed during the incident, and there were no sensor alerts, except for the tire pressure warning light. Also there wasn't any record of dashcam recording when we checked the car. We are seriously concerned that the airbags did not deploy , attached are photos concerning the damage. I would like to emphasize that my fiancée was diligently following safety guidelines and had her hands on the steering wheel while using Autopilot. This incident occurred suddenly and unexpectedly.

While on a cross country trip and while on the highway using the Tesla auto pilot and/or adaptive cruise control, we experienced numerous phantom braking incidents. Several while driving during the day with no other vehicles around and several while passing semi trucks in the other lane. At night the same thing occurred and on one occasion, with no other vehicles around, suddenly braked from 70 mph to near stop. Had we been on a wet or icy surface, there is the possibility of control issue.

Multiple times, the vehicle braked on its own while traveling eastbound on the Interstate 8 freeway between Yuma, AZ & Gila Bend, AZ. This was when no other vehicle or obstruction was on the freeway within a mile of the vehicle. The braking was very jarring, and if another vehicle was behind us it could have easily caused a high speed rear-end collision.

The Driver Assistance System fails. Specifically, the cruse control, parking assistance, blind spot monitor, display of other objects, lane identification, stop sign or traffic light recognition and other safety features fail repeatedly.

While on our first road trip in this vehicle, we engaged Adaptive Cruise Control (ACC). After about 30 minutes, the vehicle suddenly (within 1-2 seconds), and without warning, decelerated from 75 mph to under 50 mph. After re-engaging ACC, exactly the same thing happened again 5 minutes or so later. Thereafter, we did not use ACC, and the car ran fine. This was a safety hazard because if someone had been following us when these incidents happened, it could have resulted in a rear-end collision. We have not yet taken our vehicle to a service center. Since there was no resulting accident, we have not reported this to any authority. Clearly, however, our Tesla Model 3 has a safety problem.

While driving with cruse controll, auto pilot, or adaptive cruise control my vehicle brakes suddenly without warning and without any reason or danger. This has happened many times. Today on the I8 traveling from Yuma az to Surpirse AZ the car braked around 15-20 times with out reason. I held the tesla car symbol on the screen to report the problem.

When cruise control is engaged, the vehicle suddenly decelerates, (at times dropping speed by more than 20 mph in less than 2 seconds). This occurs as often as 5-10 times in a single 60mi trip, and occurs at least once per trip on this same route (divided highway, sometimes with hills, often with no other cars ahead of or around the vehicle, speed 60-70mph) These events are unsafe because unexpected braking is a hazard for following cars and my passengers. My job as a driver is to be as predictable as possible, but when I use the cruise control the car behaves unpredictability Problem reported to dealer, confirmed by remote diagnostic, and car was serviced but the problem got worse. There are no warning lamps or error messages displayed in conjunction with these sudden braking events. First appeared when the car reached 2000miles on odometer

While driving on a two lane highway I experience daily ghost braking incidents. While doing 75, in both cruise and autopilot mode, the car will slam on the brakes when approaching a semi in the right lane. Today it even swerved to the right without the semi moving out of its lane. I also experience panic braking if a car crosses the lanes in front of me even if it is 500m away and the crossing car even left the road before braking occurs.

When on a recent trip from Salt Lake City to Denver Via I 15 to hwy 6 and on I 70 When it was in cruse control and also auto pilot the car would on it's own brake. Some of the time it would brake very harshly others it would not be so violet ,but would certainly be some thing that could cause a very bad accident. The only solution Tesla service would offer was to go on a test drive to see it happen. This could take posably many miles, and then said they did not have a solution.

Vehicle suddenly brakes while in autopilot with no road obstructions. This has happened to me several times and I'm concerned that if someone is following me too close this may cause a collision.

The cruise control was set at 70 MPH. The car braked itself and tried to stop itself even though I had no cars or objects in front of me. I had to apply the accelerator to get it to out of stopping itself. It happened twice in a short amount of time on that morning. The car is available for inspection. This is a safety issue as it could have caused an accident if I had someone too close behind me while driving on freeway I-75. I have not had the car inspected as this just happened yesterday 09/22/2023 and today is 09/23/2023. There was no warning prior to this happening and no issues with the car. Again this happened on 09/22/2023 for the first time. Thank You.

Cruise control set to 82mph on interstate with no cars nearby. Car slams on brakes on multiple different cruise control sessions. Dangerous for other cars that could be driving behind me and could cause me to lose control of the vehicle.

I was driving on I-35 from Kansas City to Des Moines on 9-11-23, and three times the car experienced phantom braking (i.e. the car suddenly braked for no apparent reason) while the adaptive cruise control was activated. During these instances the car would suddenly brake and slow down and on one occasion I had to accelerate immediately to avoid possibly being rear ended. On all occasions there were no obstacles on the road or cars within 1/4 of a mile ahead of me.

While driving late at night at highway speeds (interstate Hwy), the car applied the brakes suddenly and without cause, with no cars in the proximity of my vehicle. The car was set in cruise control mode (adaptive.) It appeared that the vehicle may have picked up a reflection from the highway striping. This occurred two times during a single trip of approximately 200 miles.

On 09/08/2023 while the vehicle was engaged in Autopilot/Traffic Aware Cruise Control and at highway speeds, the vehicle suddenly braked with no visible / reasonable cue from the surroundings. Minutes later, it suddenly braked again suddenly and without any visible cause but with more force. After this, I stopped using this feature of the vehicle for the remainder of our trip. A similar event occurred around Apil 2023 and when I reported this to the Tesla Service Center they replaced both the right side and left side repeater cameras (faulty). The first incident of this nature occurred around a week after taking ownership in late October: Again at highway speeds, the vehicle suddenly and abruptly braked without cause. The Service Center was notified but they found no issue with the car. This type of behavior places myself and my family at risk of being rear ended with the abrupt nature of this kind of braking (sudden, abrupt and with no cause). It also places the vehicles that happen to be following me at risk with this sudden braking behavior - the braking is not gradual. After I reported the most recent incident, the service center did not find any faults with the hardware and said that "these behaviors are a limitation of software in the system."

The car does phantom braking on the highway when using cruise control. It is usually caused by a truck in the neighboring lane applying it's brakes, but not entering my lane.

1. When vehicle is on autopilot mode. Vehicle will all a sudden brake by itself with no reason as to why, no cars in front of me intermitly. Mostly happens when driving at highway speeds and when approaching a overpass. 2. Could be crash from the rear. 3. Have not notified Tesla. 4. No inspections have been performed 5. No warnings and no beeping either just brakes by itself intermitly.

The vehicle slowed down at a very rapid rate when in cruise control for no reason. There were no other vehicles or obstructions anywhere near the vehicle. This happened 3 times. I reported these events to Tesla and they said it was a known issue called ghosting and there was nothing to repair. A rapid deceleration of the vehicle for no reason and with no warning is a safety issue that should be addressed immediately. Iv'e used cruise control on many other vehicles and have never had a problem.

We were driving on cruise control on 7/24/23 between the hours of 6AM - 8AM on a completely open highway with no cars near and no objects in the road. Our car braked on its own when we were driving 74-77MPH bringing the car to an almost complete stop. The same thing occurred on 7/22/23 between the hours of 9AM - 2PM. It was extremely scary and an obvious malfunction/ defect of the car. We both have back pain now from the sudden stop.

The car makes unintended braking when there is no vehicle in front. The car made a sudden brake from 75 mph to near 0 mph such that the driver felt that the vehicle almost flipped.

I was on a road trip in South Dakota through I-90 and the vehicle stopped in middle of the road caused by phantom braking while running by its autopilot (7 times total). In multiple instances, there were vehicles not far behind. This is really scary as in any moment we could have been in a fatal accident on the 80mph road. Tesla needs to fix this ASAP. Not acceptable at all from a vehicle that costs this much.

While driving westbound on US Rt 50 in Nevada with AutoSteer Beta engaged, car repeatedly decelerated rapidly with no audible or visual warning presented. This "phantom braking" could easily put vehicles traveling behind mine at risk of a collision. I have been able to reliable reproduce this in certain conditions - when a mirage is present on the roadway ahead and there are no cars immediately in front, the visual object detection system is apparently thrown off by the refraction of light and incorrectly detects cars, pedestrians, or motorcycles where none exist. As I see it, there are two major problems in play here - one is that the camera-based object detection system is easily confused by the presence of mirages on the road surface ahead and there are no other sensors in other portions of the EM spectrum (IR LIDAR or RADAR) to confirm the presence of visually detected objects. The second is the lack of audible driver warning before deceleration takes place. The only indication that occurs is the energy use indicator (a thin line at the top left of the screen) shows energy use transition to regeneration. Together, these constitute a serious safety hazard for anyone operating these vehicles and those following behind them.

While using cruise control on a highway traveling between 65 and 75 MPH the brakes slammed on when there was absolutely no traffic in front of or beside us, no overhead obstructions, no upcoming corners, nothing at all but straight road ahead. If anyone had been behind us we could easily have been rear-ended. The car had only 1500 miles on it the first time it happened. There were 4 such events in our short 400 mile road trip. Took it directly to Tesla service and have been told there is nothing wrong with the car!

Car accelerated forward unexpectedly while making a turn and hit a telephone pole. Brakes did not engage nor did the forward collision warning sound or engage. Was manually driving. Car is non-driveable and repairs from Tesla are backlogged so we waiting 8+ weeks to get our car back.

The vehicle will randomly brake when cruise control is being used. No obstructions, good weather conditions and flat road.

During my first highway trip from Dallas to my home in Alpine, TX, I experienced numerous instances where the car would suddenly decelerate as if I had applied the brakes. At first I thought it was because there was a lot of road glare because I was driving late in the day into the west sun, but the next day it happened early in the morning when the sun was behind me and the road was straight, relatively clean with clear markings. The ultimate instance was when I was driving on a newly reopened dark asphalt road with new markings, straight, no glare, sun behind me. Clearly there is a problem.

I enabled the tesla adapter cruise control during my trip in interstate 15. All of sudden, the car stopped to a slow speed for no reason. There was nothing in front of my car at that time. I was able to step on the brake to disable the cruise control and step on the accelerate pedal to resume the speed. Luckily there was no vehicle behind us, otherwise it might have been a rear end collision.

While traveling on a busy interstate highway, my Tesla 3 presented four errors on the control screen: Automatic Emergency Braking disabled, Power reduced, Vehicle shutting down and Unable to drive. The left hand side of the screen flashed red and instructed me to pull over safely. The car was immediately slowing down, and as I was in heavy traffic, I was unable to pull over to the shoulder safely. I turned on my hazard lights and performed a soft reset of the car - which caused my hazard lights to turn off, all while cars were honking and whizzing around me. After the car reset, I was able to drive a short distance, with enough speed, to cross several lanes of traffic and come to a stop on the shoulder emergency lane of an exit ramp. The car is only 6 months old, with 4000 miles, but had to be towed to the Tesla service center. The problem has been diagnosed as a problem with the rear drive unit inverter and will be replaced under warranty. While I appreciate the resolution and that it will be fixed, it could have been a very serious situation and caused an accident. Thankfully, I was able to get to safety and wait to be towed.

I was driving on a rural, two-lane highway with no other cars around and with cruise control engaged. Without warning, the car decelerated suddenly and rapidly from about 60 MPH and continued to decelerate until I pressed on the accelerator pedal (at about 40 to 45 MPH) to stop the deceleration. It happened at least 5 times during a drive from Spring Grove, IL to Champaign, IL on July 7, 2023, between 10:30 AM and 2:00 PM. If there had been a car following close behind me it would have been very dangerous. I had the Basic Autopilot engaged with Traffic-Aware Cruise Control (but not Autosteer). Weather conditions were bright sunlight with a few clouds. The problem has occurred several times (at least 4 times) since then. The problem has not been reproduced or confirmed by a dealer or independent service center. I have not had the vehicle inspected by anyone. There were no warning lamps, messages, or other symptoms of the problem prior to the failures.

Emergency braking applied when no other vehicles were in sight. Braking was hard enough to spill coffee. Seems to occur when adaptive cruise control is on. Happened about 10 times on recent road trip. Lucky no one was behind us! Felt very unsafe.

The vehicle applied sudden and strong braking in clear road for no reason. It has done it on many occasions in the 2000 miles we have had the vehicle.

My vehicle constantly slows down and occasionally even slams on the brakes to slow down for nonexistent obstacles. I believe this is a serious safety concern if there is a vehicle behind mine, as the driver of that vehicle would not expect mine to rapidly slow down. The root cause seems to be that the camera vision system frequently mistakes certain signs and dark cars reflected in mirages as pedestrians.

The ADAS regularly brakes suddenly for no apparent reason. There does not seem to be a consistent reason. Yesterday, during a 90 mile drive EB on the interstate in the afternoon it braked (scaring us) suddenly so often that it made cruise control more of a hazard than a help. This morning between 9-11 am, westbound on the same interstate it braked suddenly 20-30 times. This sudden braking is dangerous as unexpected behavior could cause an accident with any vehicle behind us.

I was stopped before turning left into a parking space. I was driving slowly. The car stopped but I did not engage the brake as a Tesla will stop once the foot is removed from the accelerator. At that point the car leaped forward at full speed hitting parts of a building and a fence. I did NOT step on the accelerator. No one was injured. The airbags did not deploy even though there was $17,000 damage to the front of the car. There were no warning signals. The person inside the building was waiting for me and saw the car come to a stop.

On Adaptive cruise control mode about a set speed of 70-75mph on I-5 , the car was suddenly decelerating or braking on Freeway for no reason. I.e. No vehicle or obstacles was there which required braking during approx 3 occurrences happened on a same day of 200+ miles drive. It was deadly dangerous and increases risk for a nasty rear-end crash.

Since purchasing this vehicle in May 2023 I have had four (4) instances of the vehicle automatically braking (phantom braking) while traveling at a higher speed on the interstate using cruise control (Autopilot). This has occurred during both daylight and nighttime driving. At the time it occurred, only once was there a vehicle in front of me, but far enough away that the auto braking should not have activated.

While driving, both while using Adaptive Cruise Control and while using "Autopilot" (automatic lane centering), the car has severely emergency braked with no input from me. The conditions were bright sunlight, with mirages on the roadway in front of the car. I believe the car cannot tell the difference between these mirages and actual obstacles. The emergency braking is severe enough to potentially cause an accident, with speed rapidly dropping from 70 mph to 45mph. This is a serious defect that needs addressed ASAP.

The contact owns a 2023 Tesla Model 3. The contact stated while driving 70 MPH, the vehicle stopped suddenly without warning. The vehicle was not diagnosed or repaired. The dealer was not contacted. The manufacturer was not contacted. The failure mileage was 5,000.

While I was driving along a freeway using autopilot cruise control, the car suddenly slammed its brakes even if there was no cars in front of us. I thought it was just a fluke but it happened at least twice if not thrice during that trip. There was at least an approximate of 3 miles gap between us and the car in front, so practically no cars in front. Had there any vehicles behind us, it would for sure rear ended us.

My Tesla Model 3 has had 3 phantom braking episodes since I bought the car new in June 2023. All 3 episodes were when the cruise control was on. Without any warning, the car will violently slow from 70mph to about 25mph in a very short time. My guess, less than 2 seconds. The tires loose grip on the road surface and the car will come to a stop. In all 3 instances, I needed to apply the accelerator to get the car moving again. During all 3 phantom braking episodes, there were no vehicles behind me that could of rear ended me. If so, the vehicle(s) behind me would have no doubt rear ended me. All 3 instances occurred on clear warm days close to Yermo CA on Interstate 15. I reported this phantom brake issue with the local Tesla location and they reviewed my cars software and said nothing was wrong. The system is working as intended. Once my Tesla Model 3 phantom breaking started, I have researched the issue online and noted a tremendous amount of complaints and reports to your agency. This phantom braking needs to be fixed and until then disclosed when a customer buys a Model 3.

I have had this car for 6 months. Three times within the past month sudden braking (phantom braking) occurred while driving on the high way with cruise control engaged. The car slowed from 70miles/hour to 35-40 miles/hour without warning on a clear day on a clear road. Then the car picked up speed. The cars in the front and the rear were far away to cause any incident. This happens in a random fashion and cannot be reproduced.

When driving in highway using autopilot, the car suddenly slammed on the brakes. This made no sense at all as there were no cars in front of it.

Scenario 1: Driving mid day in hot weather in desert highway with rolling hills and cruise control activated. Upon cresting a ridge with mirages the car slams on the brakes until the mirage dissipates. Also as another car approaches and its reflection is bounced back from the mirage in the road surface the car slams on the brake until the reflection shifts or the mirage dissipates. Scenario two: Driving on freeway mid day in warm weather and brightly illuminated freeway and approaching dark shadows under an overpass. The car slams on the brakes until closer to the overpass. 20-40 mph deceleration noted. The specific freeway section had a slight descending roadway leading into the shadow and then ascended on the other side so that a continuing road surface was not immediately visible beyond the shadow.

Phantom braking occurred 3 times over the span of several minutes while driving at highway speeds. The first two incidents occurred while utilizing Autosteer. The third time occurred while only using cruise control.

On July 6th, at 6:42pm, while driving 70 MPH on California Highway 152, on a clear day (88 degrees F), with no traffic around our car, the car slammed on the brakes, taking the speed from 70 MPH to 46 MPH in a period of 5 seconds (with most braking in the first couple seconds). I was using the cars' built-in Autopilot system. The car did the same thing about 2 minutes earlier, so we happened to have been recording a video of the cars operation when it happened this second time. The car did the same exact behavior on June 29th at 10:30am, on the same highway but different location. It was also a sunny day, and there were (thank goodness) no cars near us when it happened. That time, it braked so hard it triggered the ABS system.

We have experienced several episodes of the car suddenly breaking for no reason when using cruise control. The speed is very quickly reduced a good 15 mph without warning.this is not only very alarming as drivers/passengers but it is incredibly dangerous. If there was a car following closely behind us, they would have hit us.

I was driving on a divided highway in the right hand lane out of two lanes. To the right was a grassy berm. To the left of the road was a grassy median. I was driving with the adaptive cruise control enabled and set to about 70MPH. Full self driving was not enabled. There were no vehicles or other obstacles visible ahead or to the sides, no vehicles following. Without any reason I could perceive, the vehicle abruptly decelerated rapidly. I pressed my foot on the accelerator pedal and the car stopped decelerating and resumed normal operation at roughly 40MPH. If another vehicle had been following me, the unexpected rapid deceleration could have resulted in a collision. This vehicle is a rental car owned by Hertz, and I have not had the vehicle inspected or diagnosed by any dealer, service center, the manufacturer, police, or insurance representatives. The Alert log in the vehicle computer showed at 6:16pm, code EPBL_a180: Emergency brake applied (see attachment).

Tesla has serious safety issues automatic emergency, braking Blindspot warning, Lane, departure warning, and other basic safety features which are very common in the cars these days. I purchased Tesla for my teenage child. In past three months we have encountered multiple instances where Tesla was not able to perform as promised this morning I was driving tesla loaner Vehicle when I was heading to pick up my car and someone drifted into my lane without warning and Tesla did not apply emergency brakes or generated any warning signals. I have notified Tesla service about the incident and past incidents to tesla service representative. Tesla representative at Costa Mesa office opened the service request to get the software diagnosis completed so that they can get to the bottom of it, but [XXX] from Irvine office called me and he is in denial that it is a car issue and blame it on me that it is between the car and the car owners manual, I have requested an escalation from Tesla service Center. In the meantime, I am filing this complaint so that NHTSA can start their investigation before. It is too late and some life is lost because of irresponsible behavior by Tesla and send in selling the features which do not work I have Lexus RX 350, 2017 model and all these features work seamlessly in the car , I am shocked Tesla is falsifying and and selling inaccurate features to the consumers which cannot be discovered until it is too late. Please start investigation investigation ASAP. Thank you. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Multiple times the car while on cruise control has slammed on brakes due to seemingly nothing. It's without warning our alert and it is extremely violent. It happens at least once every week.

While in cruise control vehicle will brake hard as if it detects something in front but there’s really a clear road.

Tesla's traffic aware cruise control (adaptive cruise) frequently brakes hard for no reason (aka "phantom braking"). This behavior occurs multiple times per week during my daily commute on a two lane highway. It happens at different locations, different times of the day, and with or without other vehicles around. "Autopilot" is disabled so there is no auto steering or lane centering. Unnecessary hard braking will significantly increase the chances of a collision with other vehicles, especially with higher levels of traffic. This problem is a well known issue with "vision only" Teslas with no radar and has been documented by many other owners. This issue has been occuring since the vehicle was new and is a system design issue, not a specific part failure. There are no warnings or other messages. There is currently no way to disable adaptive cruise control and use basic fixed-speed cruise control.

Vehicle automatically applies the breaks while using the cruise control. Braking occurs randomly and very suddenly at highway speeds with no warning. The car slowed rapidly to about 25 mph. This has occurred twice in the last 6 weeks in two different locations. Fortunately, there were no vehicles following at a close distance. If there had been, the sudden application of the brakes would almost certainly have resulted in a rear-end collision with the car that was following us.

The 2023 Tesla Model 3 Performance Autopilot cameras "saw" things that are not there while driving during daytime on the highway aka phantom braking. This resulted in quick automatic braking making for a very uneasy drive with fear of being rear-ended when it happens. Yes, my vehicle is available for inspection. Our safety was put at risk due to potential to be rear-ended. Also, this happened on an icy road which has potential to cause sliding. I called the Tesla sales department where I purchased the vehicle. They said there was nothing they could do and that Tesla is working on it. There are many websites discussing the problem. My vehicle has not been inspected by Tesla. They told me there is nothing we can do. I have not contacted my insurance company or police. I'm not aware of any warning signs. You are driving on a highway during the day at 80 mph, the car's cameras "see" something that is not there, and it automatically brakes hard.

I was driving from Palmdale, CA up to Mojave, CA at 7:05PM on June 16. The car was close to Rosamond, CA on the highway when it engaged FULL brakes. I started in the right lane, the autopilot was ON and set to 79MPH. The only cars visible on the highway were my car and the car in front of me. There were no other cars immediately visible to me or autopilot in front of me or behind me - other than us two. My car was traveling faster than the car in front of me, so at ~3-5 car lengths I started a left turn signal to merge into the left lane, and overtake the small car (silver Toyota?) in front of me in the left lane. When I started the left turn signal the autopilot disengaged as expected. I got in the left lane then stopped the signal, and turned ON autopilot @ 79MPH. My car started overtaking the car in the right lane, the car beside me was now in my right blind spot. Then all of a sudden my car engaged FULL brakes and went from 79 MPH to maybe 30MPH? As a reminder there were no cars in front of me or behind me. The other car was to my right. I quickly assessed the situation to confirm I wasn't going to be rear ended by the car to my right and pushed the gas peddle as hard as I could to accelerate back to 70+ MPH. I checked to see the sun was behind me so the car's cameras were definitely not blinded, I sped far enough away from the car next to me to take a photo of the area I was driving in. Please see the photo attached to see the condition of the sky and to confirm the roads were completely empty when the tesla decided to brake in its full capacity for what I believe to be no reason at all. I fully believe if there was someone behind me in the left lane even at a safe distance I would have been inadvertently rear ended as there was no reason or cause for the car to be breaking that hard. I'm sure Tesla can provide telemetry data from my car to corroborate my version of the events.

When I started the left turn signal the autopilot disengaged as expected. I got in the left lane then stopped the signal, and turned ON autopilot @ 79MPH. My car started overtaking the car in the right lane, the car beside me was now in my right blind spot. Then all of a sudden my car engaged FULL brakes and went from 79 MPH to maybe 30MPH? As a reminder there were no cars in front of me or behind me. The other car was to my right. I quickly assessed the situation to confirm I wasn't going to be rear ended by the car to my right and pushed the gas peddle as hard as I could to accelerate back to 70+ MPH. I checked to see the sun was behind me so the car's cameras were definitely not blinded, I sped far enough away from the car next to me to take a photo of the area I was driving in. Please see the photo attached to see the condition of the sky and to confirm the roads were completely empty when the tesla decided to brake in its full capacity for what I believe to be no reason at all. I fully believe if there was someone behind me in the left lane even at a safe distance I would have been inadvertently rear ended as there was no reason or cause for the car to be breaking that hard. I'm sure Tesla can provide telemetry data from my car to corroborate my version of the events.

I was driving from Palmdale, CA up to Mojave, CA at 7:05PM on June 16. The car was close to Rosamond, CA on the highway when it engaged FULL brakes. I started in the right lane, the autopilot was ON and set to 79MPH. The only cars visible on the highway were my car and the car in front of me. There were no other cars immediately visible to me or autopilot in front of me or behind me - other than us two.

Car unexpectedly brakes while using the cruise control. This can occur multiple times on a long drive without warning and for no apparent reason.

On several occasions ( 8 or 10 times) while driving at highway speeds, with little traffic, on an extended trip, the vehicle suddenly applied the brakes for no apparent reason. I have learned that this is called "phantom braking". On one such occasion, I narrowly avoided being struck from behind by another vehicle following me by applying the accelerator. I have not yet reported this problem to Tesla, but intend to.

While driving on 15 freeway between Riverside CA to Las Vegas NV, I put the car in cruise control. While near Barstow, the car hard brakes dropping speed quickly. Luckily no other car was near. I changed lanes to pull on the side as I wasn’t sure what was happened, as it actually felt like the car had locked up. I did take the car out of cruise control and that seemed to fix the problem. I’ve used cruise control before and the adaptive braking has been manageable, this was extreme. On 4 June 2023.

When adaptive cruise control is engaged, the vehicle harshly brakes. This occurs very randomly and is abrupt. The operator needs to quickly take control and accelerate as the speed is reduced significantly. One incident, the speed was 80 mph and it reduced to less than 60.

On a clear sunny day driving on the freeway at 75mph on a 70mph speed limit, the regular cruise control(not Autopilot) was engaged. Experienced 4 separate incidents of strong emergency brakes being activated by the vehicle automatically for 2-3 secs, dropping speed by 10-15mph. As the driver I disengaged the cruise control by strongly accelerating the vehicle. Also multiple incidents of brakes engaging slightly for 1 second , always when driving on a straight freeway, with zero other vehicles present in the front or rear. The road had a slight incline then a slight decline. Just as the vehicle reaches the top of the incline the brakes activated. No warning lamps of sounds, just immediate sharp braking one all incidents. As the driver I felt very unsafe, and glad there were no vehicles close behind, which could have resulted in a rear collision. Vehicle has not been inspected by any party. As a Tesla driver I do not trust the Standard Cruise control feature any more.

While in cruise control, the car suddenly reduced its speed; there is no obstacle in the path of the cat that would warrant such an action. This deceleration is sudden and violent and when it happens is dangerous for following drivers.

2023 Tesla Model 3- Consumer wrote about comparison of braking mode to non-EV's, experience driving a rented EV (Electrical Vehicle) w/ braking mode and suggestions to make EV's braking mode safer. When EV's accelerator is NOT pressed the EV goes into regenerative braking mode. No brake lights are triggered because brake pedal wasn't pressed. Consumer listed two "real world dangers". Consumer recommendation- The regenerative braking of EV's should also trigger brake lights notifying vehicles behind the EV that the pace of the vehicle is slowing with the same force. as if brakes where applied.

Vehicle breaks suddenly for no reason under a variety of circumstances. there is no pattern I could identify. i went on line to see if there is an update. many others with the same problem. Very dangerous if there is a car behind. Happens every day or so at freeway speed. Tesla needs to fix this!

When driving and using “autopilot” or just cruise control, the vehicle will randomly brake. Sometimes it brakes lightly, but sometimes it will violently slow the vehicle down, without warning. There is no obstacle in front of the vehicle. If another vehicle is behind the car when the car randomly brakes, this can potentially cause a rear-end event or potentially cause the car that is behind to swerve to avoid an accident. I submitted a service request to Tesla, but Tesla responded by stating that there was no malfunctions that needed to be addressed. They described various scenarios in which the computer would determine a need to brake.

Phantom braking. Traveling highway 5 Southbound between Red Bluff, CA and WIliams, CA at 70 mph, the vehicle suddenly and firmly applied brakes as if attempting to avoid a collision with an obstacle closely ahead. The braking force was enough to activate the seatbelt restraint. There was no traffic for at least a 1/4 mile ahead and behind and no obstacle. I managed to flip the ACC lever up to disable it during the braking but felt that I was losing control of the vehicle. After ACC was disabled normal operation ensued. Speculation: The incident occurred mid-May and the area is agricultural and therefore teeming with bugs that collect on the front of the car. The forward camera may have been hit by a bug and the visual recognition system may have mistaken the bug for a large obstacle.

Tesla 3 2023 is making hard breaks on auto pilot even though there is no objects. It’s happened over 30 times in last 7 days. It’s scary bcz other cars Coming behind can leads to life threatening accidents. Pls help

The contact rented a 2023 Tesla Model 3. The contact stated that while testing the collision avoidance system the vehicle was moving at 2 mph and the brake pedal was not depressed the collision avoidance system did not activate. The vehicle collided with another vehicle. The air bags did not deploy. A police report was filed. The manufacturer was notified of the failure. The failure mileage was approximately 30. The VIN was not available.

Mileage: 30

Car steering felt stuck and slid off the road which resulted in crashing into a tree. Tesla features did not help stay in the lane or break in an emergency.

Hello, I have experienced 2 times the same issue with this new car model. I was driving on a interstate with 2 lanes, no cars in front of me and fortunately no cars behind, I was in autopilot mode and emergency brake system got engaged for no reasons apparently (Phantom braking) and I had to take over immediately. It was scary and I was lucky that no car was behind as it could have created definitely a worse scenario. The first time I was entering a bridge and the color of the asphalt was a bit different from the main road that might have triggered this phantom braking. The second time I entered in a driving area in the shade, here the phantom braking might have been triggered by a sudden change in the sun light. Regards.

The vehicle gives false forward collision warnings which increases my insurance premium. This happened multiple times in the last month.

The car phantom brakes 50% of the time when I use Enhanced Autopilot Feature on the highway

Automatic emergency braking. Phantom braking without any real incident

At random times the vehicle will slam on the brakes although there is nothing in front of it. It has happened with vehicles behind me and I have averted multiple crashes by luck I suppose.

I was driving on the HOV lane (going between 65-70 miles mph) with the adaptive cruise control and lane keep assist on when the car suddenly slammed on it’s brakes to stop. There was a slight hump in the highway, but no car or object in front of me in the lane. Thank goodness there were no cars behind me or they could have easily rear ended me. It was extremely scary and now I’m too scared to use these driver assist features moving forward.

I was on Interstate I5 on March 16th with car cruising on Tesla Auto Pilot Assist. The road was completely clear with nothing ahead of behind me for atleast half a mile. All of a sudden I experienced Sudden Breaking (Phantom Breaking) and broke hard to about 30 MPH before resuming. I was fortunate that there was nothing behind me otherwise I would have been rear ended. The only thing I could see was there as a dip in the roadway and some shadows were falling across the highway. Tesla has no radars and I suspect the camera was fooled by the lighting.

- The adaptive cruise control malfunctioned, It sharply braked while no cars in front or arround me was braking.Conditions were clear, no rain/no snow, in the daytime. The windshield was clean, the road was clean as well (on the asphalt with road markers clearly visible). - My safety and the safety of others was put at risk, the braking was realy sharp nothing could have helped me or other users of the road predict that it was going to happen. Someone behind had to slam the brakes to avoid a collision with me. - Nothing was inspected - No warning or symptoms were visible then nor now.

I bought a new Tesla Model 3 in December of 2022. In mid March 2023 we had our first road trip in this vehicle. I had at least 4 major phantom braking incidences while traveling an average of 75 mph on I-80 with the cruise control on. Two were experienced while traveling eastbound in Nebraska and two were while traveling westbound a week later in Wyoming. Each experiece was separated in time by at least two hours. The last one scared me and my wife so much that she won't ride in the Tesla on the freeway until it is fixed. We also had several minor phantom braking experiences which did not alarm us. What happened is that the car slammed on the brakes while going 75 and reduced the speed to about 55 in seconds. It was over before I could react. The tires did not skid and fortunately no one was following us. I fear that if someone was tailgating me that they would have rear ended our car. I had experienced a couple of phantom braking events in Utah in previous months but they weren't severe enough for me to report it.

While traveling with cruise control enabled and not using autopilot, about every 50 miles or so I will encounter a situation where there is no one in front of me and the car with begin rapidly decelerating. I have had several drivers behind me hit their horns in a panic while trying not to hit my car. I am very worried that this issue will cause me to be rear-ended by another driver. This issue is occuring at both highway speeds exceeding 65mph as well as speeds speeds as low as 50 mph. It has happened on multi-lane highways with no other cars around as well as on single lane local roads.

I experienced unnecessary emergency braking while driving from Chicago to Madison on I-90. I was driving at 75 mph on adaptive cruise control with auto steer on. I suddendly I experience hard braking for no reason. I observed my set speed limit changed to 45 mph. However, I instantaneously took over and pressed accelarator. I experienced the same 2 more times during the same trip. It's created a very dangerous situation.

Driving on interstate using Tesla model 3 autopilot about 75 mph. Road narrowing from 3 to 2 lanes and I was in the merging lane approaching entry to 2 lane road. Cars were to my right, visible, but safely distant. Suddenly, unexpectedly the car started breaking, creating alarm for me, but was able to re-engage the accelerator and safely merged into 2 lane highway. If a car was closely following me, which was not the case, could have resulted in rear end crash. Had used autopilot frequently before this episode and never had this problem, and subsequently autopilot seems to be working properly. Occurred 3/11/2023.

We were driving down the road, emergency braking enabled came on and car came to a complete abrupt start 10ft from railroad tracks and would not do anything. Could not reset it. Nothing.

The undercarriage shield of my car disconnected and started dragging while I was driving in the rain. I did not collide into anything or hit a bump. I inspected my wheel well to discover a set of screws that were bunched up and not installed during manufacturing. I had to pull the shield from under my car so that I can continue to drive the vehicle. the shield is connected to the forward warning and pedestrian warning collision system which became inoperative. The faulty manufacturing that caused the shield to disconnect caused a dangerous condition while operating. After I removed it, a second dangerous condition was created since all of the safety senors were disconnected.

This model doesn't have parking assist, so every time I park there is a danger of collision. All modern cars have parking assist. Tesla promised in Nov 2022 that software update enabling parking assist will be available within "next couple of weeks". 3 months passd since then and there is still no parking asist.

Multiple times on the highway the car would slam the brakes for no reason in autopilot mode reducing the speed significantly. In all cases it reduced the speed from around 70 mph to 40 mph. The road was clear with no vehicles in front.

My Tesla Model 3 was delivered on 14 December 2022. I first drove it on 16 December 2022 and that day I had an accident. I was about to park my car and I was already on the designated parking slot when the car made a sudden Un- commanded acceleration. I first hit the handicap sign, but the car did not stop and apparently the collision avoidance safety feature did not work. The continue to accelerate and I hit a restaurant establishment. The police came and I reported the incident to my insurance (Geico). The police (Mr. McClure) gave me the case number 2238293. Geico is taking care of the repair which would cost over $10K and the property damage, which added up to 10K. I went to the Tesla service center in Carlsbad and Mr. Hyuma said that I can request for the log. I guess it is the EDR. They gave me a link to request for the EDR but the start date is 23 January 2023 way after the accident date of 16 December 2022. I have not received any log or EDR from Tesla to date. I am uploading the pictures of the car before the repair. Please help me find out what exactly happened and why the car suddenly accelerated without pressing the gas pedal. I am a retired US Navy (20 years) and I bought a Tesla to save money because i have solar in my house. I have a fixed income and cannot afford to spend money on the EDR. I believe that here is a defect on the Tesla Model 3 that I bought and I will appreciate all the help you can provide.

The contact owns a 2023 Tesla Model 3. The contact stated while driving 65 MPH, the vehicle experienced phantom braking and the vehicle stopped abruptly. There was no warning light illuminated. The contact was able to accelerate to avoid getting rear ended. The dealer was contacted and admitted knowledge of the failure; however, there was no remedy for the failure. The manufacturer was not contacted. The failure mileage was 2,000.

Mileage: 2,000

While exiting a hospital parking deck, after driving for approximately 15 to 20 seconds, the car began to accelerate to an uncontrollable rate of speed on its own. The Tesla crashed into a parked car which was then pushed into two other parked cars. The Tesla and at least the first car hit are totaled. There was no sign of the emergency braking system engaging. Injuries from the airbag deploying were sustained. The driver has a fear to drive again as the car seemed to have a mind of it's own. The Tesla is being held at the insurance company's tow yard. There has been no feedback from the dealer. No inspections have been conducted on the car. There were no indications there was a problem with the vehicle previous to the crash. It is unknown if any warning alert systems activated during the incident.

sudden, abrupt braking on multiple occasions when passing a specific location along NJ Garden State Parkway (near exit 89) while driving on auto pilot.

Driving west on 1-10 west of TLH vehicle suddenly decelerate if if there was slowed or stopped traffic ahead. I was alone on road.

I took deliver of the Model 3 Performance in late October 2022 and have experienced phantom braking at least a dozen times over the last few months on the highway/interstate when using cruise control and Tesla’s standard autopilot, which keeps the vehicle centered in the lane. The phantom braking has occurred both in times with just the cruise control enabled and also when both cruise and autopilot have been enabled. The vehicle has slowed from 70 to 60 and even 50 miles per hour very quickly when there was no object nearby that would cause a collision. This is both frightening and upsetting, as such sudden braking could cause an accident, especially with any car following me from behind. I am fearful to use the cruise or autopilot as a result of this defect.

I was pulling into a park spot , coming to a stop and the car within seconds accelerated into a building. There was no warning at all. Also, after the collision a warning popped on the screen saying that the emergency break was disabled. This was the first time seeing this alert, and I did not disable anything. I picked up the car on 11/28.

While moving car to DRIVE mode, Cruise Control was activated accidentally, which resulted in car moving on its own from a stopped position in garage. By the time it was learnt what has happened, the car rear ended another parked car. Luckily no human was in front of the car and thus grave body injury was avoided. The car speed might have been less than 20mph. The front collision avoidance warning was not there and neither did Emergency brakes got deployed.

While traveling on the interstate at 75+ mph, which the cruise control engaged, the vehicle emergency braked 2 times during on one trip. The first felt like a fluke, speed was reduced by 10ish miles per hour. The second time was terrifying. I was traveling approximately 77 mph on the interstate and out of no where my vehicle slowed down significantly. I was too scared of getting hit from behind to look at the speedometer to know how much it actually breaked but it felt like it dropped down to 30 mph out of nowhere. Luckily I was not on a busy stretch of interstate, the car behind me had enough time to slow down and there was no one else around. My husband and I were scared out of our minds, wondering why and how this happened. He immediately google and that is when we learned of 'phantom breaking" I have owned this car for less than a week and now I am scared to use cruise control. I don't even have the self driving or advanced auto pilot. Thank god no one was hurt. This is more than a safety issue, this could be life and death. I read that this particular issue has been reported more often lately. I reported the problem to Tesla but urge you to conduct an investigation that gets this matter resolved, not just for Tesla drivers but for the safety of everyone on the road.
