2018 TESLA MODEL 3 Forward Collision Avoidance Problems

Repeatedly and randomly, with cruise control (not FSD) engaged, the car would brake, sometimes aggressively. The last time, it braked so hard the tires or brakes squealed and the car swerved slightly before I was able to regain control. This was on the freeway (in Colorado, if I remember correctly) while I was cruising at 70 or 75 MPH. I decided that that was the last time I would use cruise control; it was just not safe. I had an appointment on October 22 to take the car in for service. But then a friend told me this was called "phantom braking" and that there was no fix. A friend suggested that I contact the NHTSA.

I believe my car should be included in the recall for trunk harness recall. My alert and issue is the rear camera being off due to rear trunk ruining the wiring harness that has affected many cars. This is already a recall but I believe my car missed being involved.

Main incident: Time: 2025-08-28 ~12:41 PM PST What happened: After searching for a parking space, the driver was preparing to reverse into the spot, the driver pressed up the stalk to shift the gear into reverse, a sound was heard and something showed up on the screen, the vehicle once again started accelerating and running forward suddenly and sharply (3 mph to 28 mph in 3 secs), driver tried to steer the vehicle away from cars and buildings to minimize danger, the car rushed onto a concrete curb, hit one blue Tesla, then hit the side of a concrete utility pole, and ran over a plant and last crashed into the chain-link french before it finally stops Injuries: * Spine pain for one passenger Damages: ** All tires blown out, tire falls off ** Severe damages throughout the vehicle body * One Tesla parked on the parking lot was severely damaged * The utility pole's base box was scraped and deformed * One plant was knocked down Similar case 3 few mins ago: Time: 2025-08-28 ~12:38 PM PST What happened: The driver entered a oneway parking lot, but found no available spot and was trying to back up, the vehicle suddenly accelerated on its own. The driver performed an emergency brake and stopped the vehicle. At the time the vehicle stopped, it was only about 20 inches away from two cars in front of it Injuries and damages: None What component or system failed or malfunctioned, and is it available for inspection upon request? Malfunctioning of the electronic control or braking system leading to abnormal acceleration Conflicting gear shifting and autopilot engagement design The right stalk is used to both shift gears and engage autopilot features, this design makes it very easy for the system to confuse the two actions Autopilot feature safety issues Autopilot features (whether its FSD or cruise control) should not be allowed to initiate abrupt acceleration to a dangerous speed in a low speed area (for example parking lot) Insurance claim filed, number: 25-647243342

Too fast and too close to stop sign to red light or other cars while in Full Self Drive (supervised).I had to disable it to avoid risks of accident.Even using Chilly Mode.

Backup camera recall was not fixed properly or the new parts have same issue. As a result the backup camera was not functioning. When the camera is not functioning the autopilot system drives aggressively, speeding up to the max set speed when it is not safe to do so with current traffic conditions. Had to disengage autopilot otherwise it would have crashed. Also I received an alert that the emergency breaking system was not functional. When reversing could not use backup camera.

October 12, 2024. I was using the Tesla on autopilot. I was in the far right lane and the freeway was curving to the left. The car was following in the lanes, but then all of a sudden it stopped following the freeway and drove into the right guardrail. There were no alerts by the car. It did not warn to take over the vehicle or attempt to avoid the collision. The car drove directly into the guardrail without warning and was totalled.

Car performed automatic emergency braking on driver's resumption of forward travel from a full stop when traffic light went from red to green. No oncoming vehicles or obstacles were present. Weather was clear and sunny and road was dry.

On December 24, 2024 I was driving on Freeway 5 South and all of the sudden my vehicle came to an abrupt breaking without any reason. The traffic ahead of me was of normal traffic. This abrupt breaking happened twice within 5 minutes of time span. I have notified Tesla Service Center and the service center gave me a quote of $137.50 for diagnostic and to schedule the service. I felt that this issues should be taken care of by Tesla with no charge to me. This is a safety issue. I have experienced the abrupt breaking issues with my vehicle on many occasions since I own the vehicle in 2018. Each time I was told there's no problem with the vehicle when I notified Tesla Service Center.

Two incidents while testing the most recent version of Tesla's "Full Self-Driving": 1. While driving at less than 25mph in a residential neighborhood, using the "Full Self-Driving" mode, the car was entirely unable to detect either heavy steel plates in the road (being used to cover road work) or significant potholes in the area near the plates. 2. While driving on H1 (a federal "interstate" highway) on Oahu, at approximately 55mph, using the Tesla's "Full Self-Driving", the car inexplicably slammed on the brakes. There was absolutely nothing visibly in front of the car for at least 200 yards. The car behind me had to swerve to avoid rear-ending my vehicle.

I have a 2018 Tesla Model 3 that was involved in an accident on 10/12/2024. It has Enhanced Autopilot, which was the most advanced version of self driving when I bought the car. It was engaged in "Navigate on Autopilot" on the freeway. The car was following the freeway as it veered to the left, but then it stopped following the lines and crashed into the side of the freeway. The result of the accident was a total loss on the vehicle. I had shoulder and neck pain that have not required serious medical attention, but it was almost a week of discomfort and difficulty sleeping. My insurance company has deemed the vehicle a total loss and I will have to get a replacement. There were no warning alerts and the vehicle did not recognize that it was leaving the freeway lines. I was not going over the speed limit. The car did not prompt me to take over the vehicle because of danger. It just went straight towards the freeway guardrail. The car is not drivable due to the damage it sustained.

I was driving (~42 m/h) my Model 3 Tesla on a freeway and the traffic in front of me suddenly slowed down. The driver in front of me (she was a new driver with a new car) braked hard and came to a complete stop even though the traffic in front of her was moving. I ended up colliding with her as a result. I would have expected the Tesla Forward collision system or the Automatic Emergency Braking system to have activated and prevented this crash. Further, it seems Tesla brakes behave differently when it is fully charged as the engine braking does not engage. In fact the car seems to accelerate instead. If the Tesla Forward collision system and the AEB do not work and prevent such accidents, what is the point of having these systems?

The MCU in my 2018 Tesla Model 3 failed after a software update, rendering several key safety features inoperable, including the car’s cameras and Autopilot functions. The vehicle currently has 16,600 miles and had previously received an MCU replacement in 2022. This most recent failure occurred during a firmware update, which got stuck at 50%. The Tesla Service Center confirmed that the MCU needs replacement again, but I was not given clear diagnostic logs or evidence of a pre-existing hardware issue. Due to this failure, the rearview camera, blind spot monitoring, and Autopilot features are no longer operational, which directly impacts the safety of driving the vehicle. These features are critical for safe operation and are standard in ensuring driver assistance, situational awareness, and accident avoidance. The issue has been inspected by the Tesla Service Center, and they proposed replacing the MCU at a significant cost, though no prior warning signs or messages appeared before the failure during the update.

On 9/6/2024 I was driving on I-10 E going about 70 mph in the left lane. I had engaged the cruise control but not the Autopilot because I’ve had dangerous experiences with the Autopilot phantom breaking and misinterpreting cracks in the road as lane markers and dangerously changing lanes. So even though Inoaid thousands of dollars for Autopilot I never use it. So I was driving approaching a big rig in the lane to the left of mine and the sun was low in the sky casting a shadow on the road. The car thought the shadow was a car and slammed on the breaks and almost came to a complete stop until I pressed on the breaks to release the cruise control. We are very lucky the car behind us didn’t hit us. The car behind us almost hit us and my passenger and I both sprained our necks. The same exact thing happened 5 minutes later. After that I am too scared to use cruise control which is very inconvenient when on a road trip. My car is a 2018 Tesla Model 3 that is equipped with LIDAR radar when I bought it, however Tesla turned this feature off awhile back. I never had issues with cruise control when the LIDAR was still enabled. I am very angry that a carmaker can turn off a safety feature that I paid for without my consent. I would have bought a different electric car if I had know I’d have to go back in time to the 1990’s before cruise control was invented. Most cars use some kind of radar for their cruise control systems and this seems to much safer. There are many, many complaints on line of other Tesla drivers having lots os problems with phantom braking. This is an important safety issue that needs to be addressed immediately.

I recently took my car in for a recall for the trunk wiring harness and have never had any major issues since I purchased it in 2018. Since replacing the recalled harness, I’m starting to receive several alerts from my driver assistance system (emergency brakes, camera failure). I called a service tech who mentioned there’s either a failed camera or a failed wiring harness. Looking online, I was shocked to see hundreds of other owners with a 2018 model 3 also experiencing the same issue in 2024 (assuming after they replaced the recently recalled harness). I strongly believe that these two issues are related and that the camera should be replaced alongside the wiring harness. Several people on this forum have been quoted hundreds or thousands from tesla to replace the harness (including myself) and are taking matters into their own hands by replacing with after market parts. This is a serious safety issue since the cameras control all self driving functionality. I’m shocked that it’s not already been addressed through a recall! The first time my system had gone out while on Autopilot, the car flashed and sirened and asked that I take over. Since then all my driver assistance features including my rear camera are no longer functional. Please see this forum where several others are experiencing the same issue on their 2018 Model 3s [XXX] Attached are error messages from my car and screenshots from the forum above where people have described the DIY fix and the costs quoted by Tesla.

While driving on the highway with FSD on, the car severely amalfunctioned with sudden deceleration at 4 separate ocassions. At 68 mph when changing lanes, the car suddenly decelerated. There were several cars behind us and it could have been a major multi car collision. At all 4 ocassions, I immediately took over control on steering and acceleration, thus avoiding any accident. This problem has not been reproduced or confirmed by a dealer or independent service center yet. My vehicle or component(s) have also not been inspected by the manufacturer, police, insurance representatives or others yet. Additionally, there were no warning lamps, messages or other symptoms of the problem prior to the failure.

Autopilot FSD 12.3.6 in Ohio is interpreting state route signs as speed limit signs. In Milford Ohio, the speed limit is 25mph. While traveling on [XXX] each state route sign had the max speed jump to 50mph. Then back to 25 at the next actual speed limit sign. An [XXX] sign was interpreted as 20mph. Errors is speed are dangerous in either the car going too fast or risking a rear end collision by incorrectly slowing down.

I may have figured out the common link between Tesla Autopilot crashes. Distracted operators have the accelerator pressed while the TACC is engaged, thinking (for many reasons) that the vehicle will stop if there are any obstacles in front of them. However, when the accelerator is being pressed, the vehicle will not stop. It will happily run into a wall. One second before impact, the forward collision warning turns on, followed by the ABS and the slamming of the brakes, but by then it's too late for a distracted driver. The raw Tesla "Vehicle Data" on Column D, shows "Accelerator Pedal Position (%)." I strongly encourage you to take a look at the data for the autopilot crashes and review this column to see how many had the accelerator pressed until 1 second before the accident, even if the autopilot was engaged. The 4/25/24 update to Investigation EA22002 states that in 82% of the crashes, the operator did not apply the brake until <1 second prior to impact. Tesla's Director of Autopilot Software Ashok Elluswamy also made a claim that the vehicle can switch pedals if the accelerator is pressed instead of the brake, and that technology saves 40,000 crashes per year: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Following an over-the-air software update, all audio in the vehicle stops working. This includes entertainment services, but more importantly turn signal indicator "clicks", forward collision warnings, parking assist chimes, shift confirmation and warning chimes, and various ADAS notification sounds. In some instances, the problem corrected itself within 24 hours. In another instance, it persisted for nearly a week before I discovered that unplugging the USB cable for the dashcam fixed the problem. The dashcam hard drive has been installed for over 4 years, per the instructions in the user manual, without problems until early 2024. There were no error notifications or anything else to indicate that there was a problem with the car's safety systems, or what the cause of the problem was, except for the lack of audio. I chatted with Tesla service about the issue. After discovering and sharing that disconnecting the USB drive fixed the issue, they were persistent in wanting to cancel my appointment without gathering any additional information. Here is the transcript of our interaction: Me: Unplugging my dascham hard drive from the USB port fixed it. Weird. Tesla: Oh interesting. Good to know! Do we have permission to cancel this appointment? Me: Since it keeps happening I'd like to keep it open. I turned on remote debugging in case that helps you to report the bug or something. Tesla: We have nothing else to diagnose if your vehicle is operating as expected. Me: Ok. If it keeps happening I will still want to bring it in, so let's keep the appointment. And I wouldn't say it's operating as expected. Having to disconnect USB cable to get the turn signal to work properly isn't what I would expect. Tesla: I would hate for you to bring in your car, only for us to tell you that it is because of your third party accessory, and we charge you for the diagnostic time. Me: I appreciate your concern.

The most recent software update v11.1(2024.3.10 9d92fb944d7f) was downloaded automatically and I installed it. The next time I drove, the car made uncommanded and unwanted lane changes, apparently because I could "go faster" if I passed the traffic in front of me. I did not want to go faster due to congestion and aggressive drivers where I live. I then discovered that "Full Self Driving" had been activated after the download and without my knowledge or authorization. I believe that this was an unsafe condition and wish to report it. I immediately turned "FSD" off.

I don’t feel comfortable driving this car because it is unsafe when I am on autopilot on the highway it would randomly stop the car by breaking instantly out of nowhere when there isn’t any car in front of me?! Please give me another car that is more safe to drive!?

I got a recall notice from Tesla and Tesla is still in safety violation and is refusing to fix the issue, so I need your help to force Tesla to fix their abusive ways. The recall 23V-838 is related to "when Autosteer is engaged". Autosteer/Autopilot/FSD now DISABLES even when NOT engaged, alleging "improper use" when it wasn't even being used. It also disengages Autosteer/Autopilot/FSD while driving if it detects "improper use" (even if it's detection system itself is buggy), forcing the car to slow down like in the middle of the freeway! When the battery is low and there's only a mile or two to go to a charger, the software will slow down and force the car to pull over to get a tow, taking on average 2 hours to get a tow truck to go 2 miles, rather than allowing the driver to reach the charger with the remaining battery it shows. Tesla keeps changing the battery percentage for when it shuts down. It used to be 0%, then 3% and recently 6%. This randomness creates "range anxiety" and distrust in the battery percentage being a useful indicator. Tesla should use 0% as "shut down" and leave the rest of the battery as "drivable" to reach a charger to have an accurate indicator. It also flashes alerts on the SCREEN to "Pay attention to the road", which is ironic to have a screen display to distract attention to the screen... rather than pay attention to the road. Tesla took AWAY my Autosteer/Autopilot improperly, and no one in the Service Center or Support at Tesla knows how to fix this BUG or give it BACK to me, so I can drive SAFELY like with lane centering. I paid $10,000 for this "safety" that Tesla takes away at random, claiming they can do whatever they want because they've now labeled it BETA software! This is an abusive practice the NHTSA should force Tesla to stop doing and give the power back to responsible drivers like me. Tesla abuser names include [XXX] and [XXX] . Teslas also don't detect cars in blind spots and still phantom brakes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

The new software update forced as part of the autopilot recall is terrible and the system needs to go back to the way it was. They adjustments make the feature useless. There are many unnecessary warnings and notifications, all of which destroy the driving experience and actually make the car less safe. Bring back the old system

There are two issues. 1) The adaptive cruise control brakes for no reason. If someone was behind me they could've rear ended me. 2) At night the blind spot camera is flooded by the turn signal and it's hard to see the blind spot warning. When the turn signal is on the blind spot camera shows on the screen and blind spot warning shows up as a red shaded area. It's hard to see the warning itself because the turn signal light floods the screen.

Cabin facing camera required for using Autopilot stopped working after software update requiring cabing camera usage. Technician has stated that many cameras have had to be replaced since the update requiring the use of the cameras

I had come to a complete stop at the red light for about 1-2 minutes when, unexpectedly, my car surged forward and collided with the vehicle in front of me. Initially, I believed someone had rear-ended me and caused the accident, but that turned out not to be the case. Although I attempted to apply the brakes to prevent the collision, it was unfortunately too late.

I AM WRITING TO REPORT URGENT SAFETY CONCERNS WITH MY 2018 TESLA MODEL 3, SOFTWARE VERSION 2023.44.30.5.1, AFTER THE NHTSA RECALL ON AUTOPILOT FUNCTIONALITY. I HAVE OWNED MY VEHICLE FOR OVER 4 YEARS AND HAVE NEVER HAD CONCERNS WITH THE ADAS / AUTO-PILOT / AUTO-STEERING FUNCTIONALITY UNTIL THE NHTSA REQUIRED CHANGES IN DECEMBER 2024. WHILE DRIVING ON I-405 IN GARDEN GROVE, CA, MY VEHICLE WHILE IN ADAS / AUTO-STEERING / AUTOPILOT MADE REPEATED AND UNUSUALLY PERSISTENT ATTEMPTS TO CHANGE FROM LANE 4 TO LANE 3. I HAD TO MANUALLY CANCEL EACH ATTEMPT, DESPITE MY SPEED BEING SET TO MATCH TRAFFIC FLOW. THIS ISSUE NEVER AROSE BEFORE THE SOFTWARE UPDATE FOR THE NHTSA RECALL. MOREOVER, THE VEHICLE CONSISTENTLY SIGNALED FOR DRIVER ATTENTION, DESPITE MY FULL ATTENTION TO THE ROAD, A CONCERNING NEW BEHAVIOR POST-UPDATE. THE NEED TO FREQUENTLY OVERRIDE THESE UNDESIRED MANEUVERS FORCED ME TO DISABLE THE ADAS AUTOPILOT/AUTO-STEERING. THIS PUTS ME AND MY VEHICLE OCCUPANTS AT RISK, AS I BELIEVE THE ADAS SYSTEM, FUNCTIONING CORRECTLY PRE-RECALL UPDATE, SAFELY MAINTAINED DISTANCE FROM VEHICLES AHEAD AND DID NOT MAKE UNINTENDED MANEUVERS TO CHANGE LANES. THESE ISSUES SUGGEST THE RECALL MODIFICATIONS ADVERSELY AFFECT AUTOPILOT FUNCTIONALITY, CREATING SAFETY HAZARDS. THIS IS ESPECIALLY ALARMING GIVEN THE POTENTIAL FOR SERIOUS ACCIDENTS DUE TO UNEXPECTED LANE CHANGES AND FALSE DRIVER ATTENTION ALERTS. I URGE THE NHTSA TO RECONSIDER THE RECALL MODIFICATIONS TO TESLA'S AUTO-STEER/AUTOPILOT ADAS FEATURES. IT'S CRUCIAL THAT RECALL ADJUSTMENTS DO NOT JEOPARDIZE VEHICLE AND VEHICLE OCCUPANTS SAFETY. A COMPREHENSIVE REVIEW OF THE RECALL'S IMPACT IS NEEDED, POTENTIALLY LEADING TO AN AMENDMENT OR REVERSAL, TO ENSURE THE SAFETY OF TESLA USERS AND OTHER ROAD USERS.

Dear NHTSA Representative, I am writing to express my deep concerns and seek resolution regarding the latest version of autopilot enforced in the recent Tesla recall, identified under Campaign ID #23V-838. I am a Tesla owner that’s deeply invested in the safety and functionality of my vehicle. Recent reports indicate that the mandated autopilot update has rendered the car unsafe and nearly undrivable with autopilot engaged. Disturbingly, users have reported false warnings, causing drivers to divert their attention from the road and react to incorrect information. This poses a significant safety risk to drivers, passengers, and others on the road. I wish to bring to your attention that the autopilot feature in my vehicle is currently usable, and I am hesitant to compromise its functionality based on the reported issues with the mandated update. It is disconcerting that a safety recall mandated by the NHTSA could potentially make my vehicle less safe for me and my family. I urge the NHTSA to conduct a thorough investigation into the safety implications of the autopilot update and to consider the concerns raised by Tesla owners seriously. Thank you for your prompt attention to this matter. I look forward to a swift resolution that prioritizes the safety and satisfaction of Tesla owners. Sincerely, A Tesla Owner

I wish to bring to your attention that the autopilot feature in my vehicle is currently usable, and I am hesitant to compromise its functionality based on the reported issues with the mandated update. It is disconcerting that a safety recall mandated by the NHTSA could potentially make my vehicle less safe for me and my family. I urge the NHTSA to conduct a thorough investigation into the safety implications of the autopilot update and to consider the concerns raised by Tesla owners seriously. Thank you for your prompt attention to this matter. I look forward to a swift resolution that prioritizes the safety and satisfaction of Tesla owners. Sincerely, A Tesla Owner

I received the recall update for recall #23V-838 and am currently running version 2023.44.30.5.1 with the added Autosteer alerts. I am finding the alerts to be too frequent when I am just looking forward at the road. I have used this system for five years and never have I had so many alerts that I feel like the car is making me take my eyes off the road just to see what it is complaining about. Then it just says keeps eyes on the road. Well, I already was so now I'm being distracted by these added notifications. This NHTSA recall has created a safety problem as the new alerts are very distracting.

Recently I noticed that the automatic windshield wipers are completely non-functional on my vehicle. Windshield wipers can still be turned on manually and work normally as expected in all speeds in manual control mode. But in auto control mode, they simply don't turn on at all, even in very heavy rain. This is critical because when driving the vehicle in Autopilot mode or Full-Self-Driving mode, the vehicle automatically puts the windshield wipers in auto control mode and the driver cannot change them to manual mode. So when driving using Autopilot in the rain, the windshield wipers just stay completely off all the time, even when Autopilot is displaying warning messages about severe weather. I contacted Tesla support about this and Tesla support immediately responded that this is a known issue and should be corrected via over-the-air update soon, but no ETA available.

"Self-Driving System" turned into a one-way road, going the wrong way when the road was well labeled. I have had similar problems every time I have activated self-driving over the past 6 years. It is easy to reproduce the issue at any time.

The adaptive cruise control (Autopilot) suddenly applied the brakes while I was traveling about 70 MPH on a major interstate highway. There was no reason for the sudden and rapid braking. No obstacles of any kind. I suspect the Autopilot was confused with the shade of the road from asphalt to concrete as I approached a small bridge. Software version on the vehicle is 2023.38.6.

I was traveling about 10-15 mph and my car unexpectedly activating the automatic emergency braking system. It was very scary and dangerous

I received a warning message that displayed, “Front Left Safety Restraint System Fault.” This is an engineering problem as the cables associated easily detach under the driver’s seat. Tesla has been long aware of this problem. They came out to my home and replaced the wire connection by installing sturdier connectors. I was subsequently was charged $329.40.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving at various highway speeds with the Forward Collision Avoidance Adaptive Cruise Control activated, the vehicle experienced phantom braking, causing the vehicle to stop abruptly in the middle of the highway. The contact stated that the failure had occurred on four separate occasions. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 27,000.

Mileage: 27,000

while driving my Tesla Model 3, using the ACC and self-steering option, I occasionally get "forward collision warnings" when going over a hill, where you can't see the road until you get over the hill. I have also had the same "forward collision warnings" on a flat stretch of road when there is clearly nothing in front of me in my lane. I have also been experiencing "phantom braking" episodes, noticing a pattern where they will happen as I approach a bridge overpass, as if the car thought the bridge overpass was perhaps an obstacle. These occur on a fairly regular basis, as in, at least 5-10 times per month. I drive a lot of highways, and drive approx 20,000 miles per year

Dear NHTSA, I am writing to report a safety defect with my Tesla Model 3, VIN [XXX] . On July 28th, 2023, at 3:34 PM PST, My wife [XXX] was driving into my driveway at my home at [XXX] . The weather was sunny and car was traveling at 5-10 mph. The car was not in Autopilot and the driving mode was set to Chill mode. When pressed the brake pedal to slow down, the car did not stop and went straight into my garage, causing significant damage to my home and the car. Very experienced driver and I am confident that wife was applying the brake pedal correctly. However, the car simply did not stop. I am very concerned that this is a software glitch in the Tesla car, and I am worried that it could happen to other Tesla drivers. I have tried to contact Tesla to report the issue, but I have not been able to reach anyone. I had the car towed to a body shop, but the car is now totaled and I cannot take it back to Tesla. I am requesting that NHTSA investigate this safety defect and take appropriate action to protect Tesla drivers. I am also requesting that NHTSA help me to get in touch with Tesla so that I can resolve this issue. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving down a residential street at approximately 20 miles per hour. The emergency braking system suddenly activated and the car slammed on the brakes. There was nothing in the road at all. Some people were on the side of the road and they confirmed that there was absolutely nothing in front of the car to cause the braking. The brakes engaged so rapidly that I have whiplash in my neck. This was a very scary incident and felt very unsafe. Had there been a car behind me, they would have rear ended me for sure. I feel traumatized by this event and am now scared to drive. The emergency braking warning came on at the same time the brakes slammed.

When driving using Full Self Driving or Autopilot, the car unexpectedly and suddenly brakes as if there is something on the road which is in the way even though there is nothing there. On one trip of 260 miles, the car unnecessarily braked twice on the freeway. Had someone been following too closely to me it could have caused a collision.

The issues are all related to the feature called AutoPilot, all on a highway, traveling at highway speed while using autopilot. sunny, dry, daytime 1. The car hard braked with no other vehicles or objects on roadway. I had to take back control quickly 2. The car hard braked when i was driving in the right lane and a car was in the entrance lane beside me, causing a near accident with the other vehicle which was trying merge onto lane, i had to quickly take back control to avoid a dangerous situation. 3. I was in left lane and turned on the turning indicator to move to the right lane, the car started to move lanes, then suddenly abandoned attempt, moving back to the original lane. there was no object in the target lane and there was a car behind me in the left lane wanting to pass, causing a dangerous situation. (this happened twice)

While vehicle is in full self driving (FSD), it randomly hallucinate, triggering left or right turns when the mapped course is forward. This has occurred 8-10 times within the past week. I stopped using it today after a near accident while driving on the highway. I reported all incidents to Tesla, they historically do not respond to inquires. This is extremely dangerous to the driver, other drivers, and demonstrates Tesla’s neglect in releasing beta releases to the public. No warnings were displayed at the time of each incident. Tesla has my driving data, camera access and my feedback notes. TeslaFSD version is v11.4.4 or 2023.7.20.

Software bug for sure. When car is in autopilot the windshield wipers start and cannot be turned off. This occurrs when the windshield is clean , not raining. The wiper off virtual switches cannot be turned off and the only option is to switch from auto to 1 to slow the wipers. If the car is not in autopilot the issue doesn’t not occur and the wipers operate as they should.

Vehicle has experienced dramatic increase in so-called phantom braking incidents when adaptive cruise control is turned on. The vehicle suddenly and forcefully brakes for no apparent reason even when there are no vehicles or other hazards in front or on the sides of it. I have revisited sites where the incidents have occurred to see if there is some environmental factor such as reflective signs that might have triggered the incidents but have been unable to replicate them. They are completely random. I am aware that this phantom braking issue has previously been reported but based on a review of various Internet sites such as Reddit, owners have reported a dramatic increase in incidents over the past month or so.

I have owned my Tesla Model 3 since early 2019. The adaptive cruise control worked incredibly beautifully for years up until a few weeks ago - I think sometime in June 2023 (could have been May 2023). All of the sudden, I was *frequently* experiencing phantom braking, ie. braking with no explanation, while using adaptive cruise control. Sometimes the braking was gradual, other times more forceful. It would happen at random places - Sometimes in/near intersections or around other vehicles, other times just out on the open road with no vehicles or stoplights anywhere in sight. Even on a 20 minute drive, it can happen three or four times. To me, this is a severe hazard. I have a disability, and I purchased this vehicle because of the incredible safety features. Prior to this, it has 100% lived up to what people said about it - just amazing. But now, the very reason I purchased this vehicle, its advanced safety features, I find not just unreliable but somewhat terrifying. I *believe* that Tesla may have (effectively / unintentionally) disabled the built-in radar in vehicles like mine. This is because I've read online accounts of people with the same year having the same problems as mine, also at around the same time that mine started. Specifically, my model year has radar built in. But I understand that newer Teslas rely solely on cameras, ie. "Tesla Vision." I understood that because my vehicle physically has radar installed, that my adaptive cruise control would still work at least as good as it had in the past - certainly not worse. If this can't be fixed I'll be forced to sell the car, which I desperately don't want to do, as I love the car and I think the world of Tesla. I just want it to work properly again.

Driving on the highways in cruise control. Car auto braked when going under an under pass. No other cars in front to trigger.

The contact owns a 2018 Tesla Model 3. The contact stated while driving with the Adaptive Cruise Control set to 75 MPH, the vehicle decelerated quickly to 45 MPH. The contact stated no warning light was illuminated. The contact was able to drive to his destination. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was approximately 80,000.

Mileage: 80,000

Driving in Full Self Driving mode, the vehicle made a left turn into oncoming traffic.

Owner driving route on 680 approaching Omaha 6/9/23 at 4:43. Car abruptly slowed and braked while passing a semi truck in the right lane on a curve. Regained control by pressing accelerator. But the reduction in speed was large and could easily have caused a rear end collision had a car been following at the time. Logged using In Car Bug Report as instructed previously by Tesla Customer Support. However, follow up with Tesla service center was unproductive.

Tesla Cruise Control was in use when passing a white van or suv on route 505 near Winters. On Friday May 19 at approx. 5:45PM. Our Tesla abruptly slowed from 70mph to approx 50mph before our driver regained control. A motorcycle following was forced to pass us using the left shoulder. The motorcycle was following at a safe distance but was put at risk due to abrupt slowdown by our Tesla. Tesla Customer Service checked vehicle remotely and states there are no current problems with the car. No alerts. Cameras are aligned. Tesla advised computer reboot and ongoing monitoring by owner. States that car may learn over time. Car is equipped with "Full Self Driving " feature but only "Cruise Control" was in use at time of event.

2018 Tesla Model 3 was in cruise control (not self-drive) on an interstate with no other vehicles in the near vicinity. The car repeatedly applied brakes unexpectedly. I have traveled with this vehicle before and did not have unexpected braking problems. I have requested a Tesla service appointment but do not know if Tesla has an answer to what I hear is a widespread problem.

This is an issue regarding the full self driving software. My car continues to run red lights at which it is already stopped. The light is solid red to the naked eye, and the camera definitely does not show the normal steady blink of a malfunctioning signal. The pitch forward in the video is me slamming on the brakes as the car tries to run the light (about 28 seconds in). I have previously reported this to Tesla on 12/28/21, 8/25/22, 9/21/22, 11/21/22, and 4/24/23. It has happened many more times than that, as I usually don't see a point in reporting the same bug multiple times on the same software version. As far as I know, nothing is being done about this and I have received no acknowledgement of the problem. The [email protected] autoreply states that they forward this information to the correct department. This is, in my opinion, many orders of magnitude more serious than the previous Tesla recall regarding waiting too long at stop signs as this will cause a crash for an inattentive driver. https://youtu.be/ZvJASdlEEPU

Multiple "phantom braking" events in which the car, on a clear day & no cars around, would suddenly slam on the brakes and try to stop. No messages were displayed on the screen. Tesla Service seems uninterested as it is a "software" issue. I tried a full reset of the car with no improvement.

On a trip today from Pasco wa to Spokane WA (us395) there autopilot and full self driving would randomly phantom brake for no obvious reason. It happened every 5 minutes or so in both directions. Scary and dangerous.

The contact owns a 2018 Tesla Model 3. The contact stated while driving 65 MPH, the contact attempted to activate the Autonomous Self Driving feature; however, there was a message stating that the Forward Collision Avoidance: Adaptive Cruise Control inoperable was unavailable. The vehicle was taken to the dealer for diagnosis and the dealer stated that an unstated computer needed to be replaced due to overheating. The vehicle was not repaired. The manufacturer was contacted and stated that the vehicle was not under recall, and that the Warranty had expired. The failure mileage was 99,000.

While attempting to park the car in a parking lot, the car did not respond to the release of the accelerator or the press of the brake but just continued. Car continued to jump the curb and run into a concrete wall without slowing or stopping. No auto functions were enabled on the car. Car was attempting to park in the spot on the right side of the photo but just continued on and ran into the stone wall.

This is a report of suddent unintended acceleration on a 2018 Model 3 performance with 47,800 miles on the odometer - the first known occurrence on this car. At 50% state of charge, I drove the Tesla on a 10 minute trip and pulled into an underground parking garage with 3 lanes of valet parking. At about 5-10 MPH, the forward collision warning came on as I was driving towards the cones and stop sign. I brought the vehicle to a full stop with the friction brakes (not regenerative braking, which was set to LOW). The drive mode was set to HOLD, which lets the car roll forward but not backwards and doesn't CREEP when foot is off the brake. About 15-30 seconds after coming to a complete stop, my foot was hovering over the brake with maybe slight pressure up to 5%. The car suddenly lurched forward with wide open throttle type acceleration. It has over 450 electric horsepower from 2 motors. The car moved between 2 feet and 5 feet. My passenger noticed and asked what I did, if anything. I did not ever once touch the accelerator. Since my foot was on the brake pedal but not pushing hard on it, I was able to depress it with my foot and stop the car. There was a concrete wall perhaps 25 feet in front of the car. No people were in the front of the car. I was at the stop sign in the garage where valet takes over. I do not know if the car would have kept accelerating if I wasn't able to engage the brakes hard.

During rush hour traffic on Highway 101 Southbound near Redwood City, I experienced an incident while utilizing AutoPilot and AutoSteer. Despite being in stop-and-go traffic, the vehicle did not respond to the car in front which suddenly came to a complete stop. Neither the Automatic Emergency Braking system nor warning sounds, which has been known to activate erroneously, were triggered. As a result, I was forced to manually brake at the last moment, but there was not enough time for manual intervention and the vehicle collided with the car in front. It is worth noting that every other instance in which I have utilized AutoPilot and AutoSteer, which occurs on nearly every trip I take, the vehicle has been able to respond and brake, albeit with slow reaction times and close distances.

Hello, The side camera in our Tesla model 3 have stopped working. Because they have stopped working, the GPS, and the car status (360 overhead view) parts also stopped working. This means that we can't use the Enhanced Autopilot with the car. This is a huge issue as the side cameras and the car status are very important for safety. It looks like this is a known problem but Tesla isn't issuing a recall to fix this https://www.cnbc.com/2021/12/06/tesla-is-replacing-faulty-autpilot-cameras-in-some-model-s-x-3-cars.html This started happening in mid-Jan, when our car had 41K miles and 4 years 1 month age. Tesla's warranty only goes 40K miles and 4years

Full Self Driving was engaged, my hands were on the steering wheel, and vehicle made very unexpected and wrong turn sharply to the right directly into a barrier with front bumper. I have the incident recorded on the dash cam. The time from the sharp turn until the collision was less than 0.5 seconds, not allowing driver response. I have the video of the dashcam recording of the accident. Tesla also has the cabin recording of my engagement during the accident. I cannot send the video through this web page unfortunately

FSD Beta code version: 2022.44.30.10 seems to have a nasty bug where due to some bad speed limit data for highways, will automatically change the max cruising speed set by me. Hence the car results in abruptly slowing down on the highway. I have filed bug reports via the car as soon as its happened. Locations it has occurred: On I-90 eastbound right after the Framingham on-ramp around the place where the service plaza exit happens. And on Route-2, eastbound between the I-95 offramp to Rt-2 thru Rt-2 exit to Winter Street. Its due to bad navigation data as the speed change happens very predictablely in the same area, regardless of road conditions, car position in lane, or weather conditions. This never happened in the past 4 years. FSD automatically changed max speed from 75 to 61 miles per hr, causing the slow down.

The contact owns a 2018 Tesla Model 3. The contact stated while driving at various speeds, the vehicle experienced phantom braking. There were no warning lights illuminated. The contact stated that there was no vehicle or objects around the vehicle at the time the failure occurred. The contact was not using autopilot at the time the failure occurred. The contact stated that the failure had been reoccurring while driving. The contact stated that the failure reoccurred while driving at 5 MPH with her 12-year-old son sitting in the front passenger’s side seat. The manufacturer was notified of the failure and informed the contact that they were not aware of the failure and the issue would be escalated. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 20,000.

While driving a Tesla Model 3 on an interstate highway at a speed of about 75 MPH with Full Self Driving engaged, the car aggressively applied the brakes for no apparent reason. This action could cause injury to passengers in the vehicle or an accident involving another vehicle that is following too closely. No information about the reason this occurred was presented. Tesla is aware of this issue.

The automatic wiper does not always work. Set to auto but despite poor visibility on the windshield, it failed to start until I manually adjusted the wiper control on the screen. With poor visibility and having to look at the infotainment screen to adjust wiper while vehicle is in motion, my safety was put at risk. Every time it rains, the auto wiper is unreliable and often fails to start or is too slow to start as if there is a huge delay and does not keep up with in heavy rain as it sometimes wipes too slow and I have to look at the screen to find the settings for the wiper to manually override the wiping speed. Also, the adaptive cruse control accelerates too aggressively at stop and go traffic causing hard braking by the car and I worry this will cause rear end collisions. The blind spot side cameras are unusable at night when turn signal is on as the light blinds the camera image and can’t see anything from it, multiple visits to service center and they told me it is normal and refuse to replace but this cannot be normal as the image from the camera is blinded by the turn signal.

Significant phantom braking issues on two lane highways like US95 in NV. The vision system cannot reliably tell if something is in the road or not when there clearly is nothing, cars or objects. Unclear if my 2018 if the radar is still active, but the vision software cheats I believe by using traffic in front to know the road is clear, but when there is no traffic on a rural highway, it panic stops from 70mph down to 45mph quickly before I can disengage Autopilot. No shadows over the road, no tree, no over passes. Happened several times going south on US95 south on a cloudy day and several times going north a few days later on a sunny day. At all times nothing in the road. It seemed to be more confused on slight rise and downhill, but occurred in even flat road sections. I think the AI has not been trained in non-traffic rural roads and unclear if the radar is still active.

While on Adaptive Cruise Control on a highway at 70mph, the vehicle’s autonomous system triggered an emergency brake causing the speed to drop down. Reacted and immediately sped up to avoid any possible collision from vehicles in the same lane. No obstructions in the lane or the immediate lanes at the time of the incident. No weather related occlusions (no rain, haze or fog)

When driving on the highway and using the "autopilot" lane assist feature the care will automatically change the set speed limit and hard brake which puts my passengers and I in danger of being rear ended due to the abrupt stop. For example I have been driving on the highway with the autopilot set to 65mph and all of a sudden the speed will change to 35 and execute a hard braking maneuver. To compensate for this I have learned to hover my foot over the accelerator to counteract this phantom braking. When this happens there are no alerts that there is something in my path that I need to slow for. Other times there are forward avoidance alerts, but there is nothing in the path. The manufacturer has done nothing to remedy this issue.

This summer while driving on interstate highways the Adaptive Cruise Control (with and without all other driver assistance/autopilot features enabled or disabled) would unexpectedly brake the car, slowing down by 10 or more MPH over 1-2 seconds, with no obstructions or vehicles in front of the car for hundreds of meters at least. This happened repeatedly, and we believe we correlated it to cases when the car came up over a low rise or bridge, and there was bright sun creating a small mirage in the distance on the highway in front of the car without any other vehicle in between to block the view. This seems to be a safety issue because at highway speeds, unexpected braking is very disruptive and startling to the driver, the passengers as well as anyone following behind who may not react in time especially on a clear sunny day with no obvious obstructions to take extra care of. * component: Adaptive Cruise Control (with or without other Autopilot ADAS features) * safety: Braking at highway speeds is disruptive to traffic and can cause accident (rear-ending, startling driver) * reproduced: Problem has not been reproduced by the vendor and I don't see any way to report it to the vendor * inspection: The components have not been inspected by others to my knowledge, this is based on software produced by or licensed by Tesla * warnings: no warnings were produced before or during the event, just .5g or so (not measured) of braking unexpectedly

The contact owns a 2018 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 22V702000 (Visibility) however, the part to do the recall repair was not yet available. The contact stated that the front driver's side and passenger's side windows failed to operate as needed intermittently. There was no warning light illuminated. The vehicle was taken to Tesla Service Center where it was diagnosed that the failure was related to the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. Additionally, the contact stated that he had been receiving notifications on the center display indicating that the visual ability of the camera on the front driver's side of the vehicle was faulty. The manufacturer was made aware of the failure, but no assistance was provided. The vehicle was not repaired. The failure mileage was unknown. Parts distribution disconnect.

While using the traffic-aware cruise control in my Tesla model 3, going down the highway with cruise set at 75 and no cars around, the Tesla suddenly braked unexpectedly and with no visible cause. I then googled for similar tesla experiences and saw the gov was investigating this on 2021 and 2022 models, however my car is a 2017 or 18 and exhibited the same situation.

Front wiring harness corrodes causing steering control to corrode. This also affects lane keep, braking, and speed control. At least 6 warnings associated with the short circuit

Phantom breaking. I was on cruise control only (not FSD mode) on HWY at 65 mile/hr, and my car breaking suddenly to 45 ml/hr until I took over. No one injured and no accident. There was a car behind of me when it happened, and the car changed line immediately.

Multiple times when using the Auto-Pilot feature the brakes will engage and dramatically slow down the car for no reason. This has probably happened 5-10 times. At this point it is getting concerning. Luckily, no cars have been following me closely enough to cause an accident, but I'm afraid that this will occur at some point unless this is fixed. I am usually driving on the highway and there is nothing in front of me and the brakes will engage. On the screen I see arrows in the passing lane flowing in the opposite direction. I'm not sure what this means or if this is triggering the brakes.

While driving on a four-lane Interstate Highway and using the adaptive cruise control, the car suddenly decelerated with no obvious cause. We were well behind the car in front of us -- the cruise control was set to 7 car lengths. I pressed the accelerator as soon as I could to resume speed. Fortunately, there was no vehicle close behind us, but a vehicle closely tailgating might have crashed into us.

While in Cruise control: I.e.going 70 + mph, when passing large trucks (18 wheelers) the vehicle will hard break down to 50 mph. Vehicles traveling behind don’t expect this and are barely able to stop from hitting into my back end. Only happens with large 18 wheelers, seems to be Trucks that are white in color. It has happened several times previously, stopped at dealer, told nothing wrong, record if it happens again.

Car frequently brakes for no apparent reason when driving on the freeway. This happens when either adaptive cruise control only or autopilot is used. For example, it has happened on a divided highway during daytime, in good weather, with clear lane markings, with no obstructions. It also happens sometimes when certain road signs come into view, such as "Caution" or "Men Working". There was no phantom braking problem with the car prior to 2021, when a software change was made. It is scary and dangerous for the car to slam on the brakes without any reason. I have stopped using adaptive cruise control or autopilot because of the risk of being rear-ended on the freeway.

Very recently Tesla had a standard software update for the car. They happen all the time. There was no warning with this update (or any update I’ve seen) about removing paid for features if you install the update. This one disabled my radar and turned my radar based autopilot I specifically bought this car for into vision based autopilot. I paid $15k for full self driving and never requested the beta to use it because I specifically did not want to disable my radar because of safety concerns. They did it anyway now, and without warning. It phantom brakes now all the time and it never used to and the general autopilot performance is worse and unsafe. I can’t use it reliably anymore and Tesla refuses to downgrade the firmware or do anything to re-enable my radar and I’m absolutely livid. This is a $75k car that I got for this one feature and they took its functionality away from me without warning and won’t give it back. Vision based autopilot is not safe and I am afraid anytime I use it now. Radar based autopilot felt so safe it was relaxing much of the time.

On Sept. 9th, around 9:05pm, my wife was on the driver's seat, FSD was engaged. so the Tesla model 3 car was driving itself on highway 395 close to susanville. Then suddenly a car coming, we had a head-on collision, the other car's front left hit our front left. The other driver passed away, my wife and I got serious injuries, we are recovering from 3 surgeries. 1.FSD did not give alert or warning, 2.FSD did not break the car, 3.FSD did not slowing down the car 4.FSD did not change direction of the car. 5.FSD just kept the speed and direction. “Disabling FSD” needs time, my wife did nothing, because there was only few 10th of a second. But I am afraid if she was driving without engaging FSD, she might be able to steer the car slightly to the right to avoid the accident. CHP will pull data from the car in the next few days. We would like to request NHTSA has a full investigation of the accident. Attached please find a form we received from CHP, a picture of both cars, and driving data downloaded from Tesla web site.

Constant "phantom braking" occurrences despite great conditions (sunny, no wind, good visibility, low traffic) during a road trip that was two hours both ways. Typically happened when coming to the crest of small hills, or when "road mirages" due to light refraction, or when a car in the distance just became noticed by the vehicle. Happened both on divided highway and two lane highways. Several braking occurrences were pronounced enough to be likened to not quite slamming on the brakes, but definitely applying them firmly. This, besides being terrifying and attention grabbing, itself a safety issue, it could also mean close following vehicles may have to react in such a way to also apply brakes heavily at highway speeds which could cause a rear end collision or swerving to avoid my vehicle. I also get little to no warning it's about to happen, until it does, no alarms go off, and in general it was noticing the hills, mirages, and vehicles just coming into the car's "sight" that the correlation of the phantom braking was occurring. I know this is known by Tesla, and I am going to take it in for a winter tire swap this week, and let the dealer know it is a major issue with my car.

My Model 3 often breaks for no reason when using autopilot on freeways. Even though there is no vehicles around my car, the car "phantom brakes" often causing me to slow down extremely fast with no warning.

As I enabled the FSD Beta ADAS system, the vehicle accelerated inappropriately quickly away from a 90 degree stop. While continuing on the road, the vehicle braked inappropriately for oncoming cars within their lane, inappropriately braked within intersections, inappropriately braked for turn radius, and was unable to avoid a closed road marked with signs and cones. Steering input was erratic, and I believe the vehicle created an unsafe condition for myself and the vehicle following me. There were no AEB or FCW alerts, the system did not display any error messages, and appeared to be operating fully.

On a recent trip from northern califorina to southern california, I experienced 5 episodes of phantom braking, that involved my brakes being applied at 75 miles per hour when no other vechiles were around me. This also happened 3 days later 4 times when traveling from southern california to my home in northern california. all incidents happened on hwy I--5 I have contacted Tesla service and they tell me nothing is wrong after checking vehicle logs. I believe this is a known issue, that is why i am reporting it. my first trip was sep 1st and second trip was sept 4th In all incidents adaptive cruise control was engaged

During use of Full Self Drive vehicle brakes unexpectedly. Sometimes vehicle studder brakes and other times hard brakes. This has caused a concern with drivers following me as well as passengers I'm my car. Also on a two lane road with double yellow while stopped in traffic, vehicle attempts to exit lane to pass stopped vehicle, in essence breaking the law.

Traffic aware cruise control (TACC) frequently and sometimes violently brakes when there are no obstacles. This potentially puts the safety of myself, passengers, and other drivers at risk during these events. This events occur without warning. Since the purchase of my vehicle in 2018 the events have gotten worse through software updates. I would expect improvements through subsequent updates not a regression.

On two occasions while on adaptive cruise control, my car slammed on the brakes while driving on the interstate going 65-70 mph. This was terrifying and the car practically stopped in the middle of the road. We are very lucky no one hit us from behind and that we did not lose control.

Newer software disables existing radar in the car; this "Tesla Vision" is objectively worse at providing automatic braking response correctly, often scared literally of it's own shadown Newer cars don't even include the rdar, an ill-advised cost saving initiated by Tesla

regularly when autopilot or cruise control are engaged, the emergency braking will abruptly slow the vehicle when no object is on the road, highway, or interstate. This creates an unsafe environment when vehicles behind you are not following at a safe distance. We have had several instances a month where the vehicle will slow from 75 to 30 in a few seconds and require human intervention to speed up. This issue has been ongoing since we received the vehicle almost 30,000 miles ago.

Driving down the freeway with Autopilot engaged and the autopilot started hard braking in the middle of the road going 70mph. No accidents occurred but it was a very dangerous situation

While driving my vehicle, no matter if I am on the interstate, country roads, side roads the vehicle will brake for unknown reasons. It will go from 65mph to 35mph, or 55mph to 45mph, etc. This happens whether in cruise control, auto drive or manual drive. It also will brake behind trash trucks with their flashing lights on, intersection flashing lights or warning flashing lights on the side of the road. It has also done it at night with oncoming vehicles. This is a daily occurrence. I have contacted Tesla service center on a few occasions and I am always told it is a computer issue, there is nothing that can be done. This is an extreme SAFETY issue and can cause a rear-end accident or another type of accident. I can not believe this issue has been going on for years and Tesla can not come up with a solution.

This defect is regarding Tesla’s FSD (beta). In the FSD mode, the car switched lanes without noticing the presence of a vehicle in the destination lane and caused a non-fatal accident. I was driving on O’Shaughnessy blvd in San Francisco around 8:50 AM. The weather was clear, and traffic was moderate. I had turned on FSD and entered my destination address. I stayed below the posted speed limit as I was new to FSD and wanted to stay extra alert. At this point, O’Shaughnessy is a single lane on each side. The lane gets wider as it nears a major intersection (Portola Drive). And then it splits into two lanes. Finally, the right lane becomes the right-turn-only lane. Per the route, the car was supposed to take a right turn at the intersection. When the lane split into two, the vehicle remained on the left for about 30 feet. Then it rapidly began to shift to the right lane by giving a signal. However, the vehicle behind me had moved into the right lane by this time. My car did not notice the vehicle as it tried to move to the right lane. It hit the other vehicle. This shift to the right lane was so rapid that I could not react to the impending collision fast enough. The other vehicle’s left-hand front fender hit my passenger door. Even as the vehicle collided, Tesla’s advanced driver assistance system failed to notice the presence of the other car. It did not give an alarm. My Tesla had all available safety warning options on. Since there was no injury, we did not file a police complaint. We notified insurance companies. This is a severe safety defect where the vehicle fails to detect the presence of another car in the lane. Not only did it proceed to change the lane, but its ADAS also did not warn of this obvious safety situation. There was no visibility issue, and vehicles traveled below the speed limit. The FSD is a safety hazard because it fails to notice a normal vehicle and switches lane.

I was driving in rain with lane keeping assistance enabled. As the car followed a curve, my tires began to hydroplane and the front end began to lose directional control and drift to the right of my direction of motion. I overrode assisted steering and attempted to keep the front end aligned with the rear so as to avoid a spin. At this moment, I felt the adaptive cruise control add torque to the rear wheels which pushed the rear tires out from behind and aggravating the planing, and defeating my effort to keep the car aligned. I suppose I then fully disabled the cruise control, but the car had already rotated too far to recover directional control, and it spun 180 degrees (front wheels trailing the rear wheels.) This continued briefly until turning tail first up an earth embankment before coming to rest. There were no cars immediately near me at the time or it might have resulted in a multi-car collision in a hydroplane zone, with a good chance of multiple serious injuries. The vehicle was inspected by the insurance adjuster and repaired. The car is available to examine. There were no indications of a system failure and Tesla did not concede to any. I contacted Tesla service and requested to examine the control system data to assess if the adaptive cruise control had contributed to the loss of control. After providing a Tesla agent with the time of the event he asked for, he reached back to me and stated that they were able to archive the data from the time of the accident. However, since I had claimed that the design might have contributed to the crash, Tesla had prohibited him sharing that data with me and custody of the data had been taken over by Tesla legal department. He added that for me to see the data, I would have to obtain it through Tesla Legal. I emailed Tesla Legal with my request on 5-25-22. I have received no response. Tesla claims the car has electronic traction control. I think this accident demonstrates flaws that can make situations worse.

With NO WARNING, and while on AutoPilot-Full Self Drive, our Tesla TOTALLY HARD AND LONG BRAKED out of nowhere, THRUSTING our necks forward for four seconds until I could disengage the brake, then SLAMMING our heads to the headrest. I have a CERVICAL SPRAIN, WHIPLASH, and a CONCUSSION! I was driving 65mph. I’ve been to the ER, to a chiropractor, and to physical therapy since this incident Sunday, July 31, 2022 at 6:37-6:38pm. On the 405 South. I’ve reported it to Tesla Service who said it was escalated to the Fremont location Engineers to review which takes 2-3 months! I have INJURIES! Phantom braking is usually unwarranted and terrifying but has not HURT ME until this time. I was almost HIT by the car behind us!

Phantom braking that causes the vehicle to suddenly apply the brakes for no reason. Issue occurs at least once each time I use the Autopilot. Occurs on interstates as well as highways. In my 6 hour drive today it happened 5 times. Each time the vehicle decreases in speed by 15-30mph. This is extremely dangerous for vehicles following behind and for the passengers who are suddenly jolted.

I have the issue recorded on video. The computer display totally froze for several minutes while driving on the highway. The turn signals would not work while the computer was frozen and the system needed to reboot after several minutes before the turn signals would start working again. I was in autopilot at the time of this happening. Video documentation can be provided. Here is a link to the video of the safety issue on Google Photos: https://photos.google.com/share/AF1QipMUiX6JR5ppOGGqTCRlWxH1Hiv7hLr2Gm9G5wjjIfYFKz4-Lg7D-_nfAzTTalFX3Q?key=anRJQWo3TGNiM0F1cEJOczZOZ3RTRnRQMm1WOFpB

I have noticed unwarranted braking while using cruise control. I have been able to confirm at least some of it is due reconstruction of the highway. At certain places the car thinks I am on an exit ramp with a 45mph limit when I am actually on the main highway. It then suddenly slows the car until I correct it using the accelerator.

After purchasing the Autopilot feature on February 9th, 2022, on our first trip next day (Feb 10th), we experienced phantom braking with adaptive cruise control turned on, barely avoiding a hit from the rear by a truck in Toledo, OH. Later, during same trip, we experienced phantom braking with both ACC and Autopilot features turned on, and stopped using them out of safety concerns. After a new occurrence, while on cruise control on June 4th, I informed Tesla service in Clarkston, MI, but no repair, deletion of Autopilot and reimbursement was possible as I requested. We never had similar issues form November 2nd 2018 to February 9th 2022 (44.159 miles) , before purchasing and installing Autopilot.

Constant phantom breaking while using cruise control, autopilot or FSD. A reoccurring problem that happens more and more often.

My Tesla 3 suddenly braked while driving on the road from about 40 mph to 10 mph. There was nothing obstructing my car from the front or sides. It was a scary experience. My neck was jolted forward and the seatbelt pressed very tightly against my chest. I immediately scheduled for service with Tesla. I then got a call from them and was told I should be okay to drive my car until my scheduled appointment a week from now! How is this not an emergency?!

The car brakes by it and accelerates by it. Some time it says I am not holding the steering wheel and it cancels the autopilot in the middle of the long distance driving. The defective cabin camera does not see the hand position at all and randomly keeps on distracting from the front road view to the screen which is not in the same line as the road. Too many errors of auto pilot are very frustrating and distracting. The Tesla’s team tries to repair something and keeps on blaming their own departments not to fix things correctly. I have tried many times to make an appointment thru their app which is very buggy and it’s like one way communication. I have multiple recalls on my car but they don’t have time or parts to fix it. They will not allow making any weekend or within 20 mile radius service center. Once they do any repair their technician drops the ball and do not want to fix the original problem correctly. The full self driving is ridiculous I have not been able to complete even 10 miles trip without taking over in few minutes. This FSD software/hardware needs to be more accurate as soon as possible so that there is no harm done to the driver and passenger to the Tesla and other cars.

1) Ongoing issue with car braking suddenly when no other cars are ahead of it. 2) When in auto-pilot, the car brakes late when carrying speed. This has happened when the car is less than 1 car length behind the car ahead of it forcing me to disengage and brake hard to avoid a collision. In one incident, I had to swerve the car and drive onto shoulder of the highway to avoid a collision. 3) On 7-16 the the undercarriage cover detached from car while driving on highway.

Since I purchased this car new in Sept 2018, the car has had a "front Left safety restraint system fault". It has been fixed over 3 times and it is going for the 4th time now. The car is going out of warranty this year and I am afraid I will be stuck with the bill if it happens again. Even though all the fixes have been free so far, it is an ongoing problem Also, the known phantom breaking, just add to the numbers. it is more than common. I almost see it coming when going under overpasses because of the shadow. The computer must see it as an object. I have inquired about the lane departure warning and they keep saying it is just a software issue. If it is activated at any point during the drive, then it says that "lane departure warning" is not long available and may be restored on the next drive.

Ghost braking hard and want refunded for full self driving because it’s not there

Driving today on I45 between Dallas and Houston on beta autopilot I was traveling at the speed limit of 75 with much room to the next car, maybe 1/2 mile the car suddenly did a panic breaking for no reason. I took control by the time it was at about 30 mph and got back up.to speed but I'm positive the car behind me was alarmed. No damage or incident but it was quite alarming.

Autopilot failed and crashed into another car while changing lane didn't detect coming in left lane and tried to changed and crashed into it. It put everyone in the car in life threatening risk

Every time we have it on autopilot on the tollway, we experience phantom braking at the same location regardless if we are going south or north. It is dangerous if there is a car behind us.

Going down an undivided single lane each way roadway at 55 MPH car suddenly hard braked and car behind me almost hit me. Most of these I don't report since it's normal for Tesla FSD or adaptive cruise to be incapable of maintaining reasonable speed for a day trip - this was worse than usual and almost resulted in an accident.

Cruise control was engaged at 70mph. Auto without warning while traveling suddenly started severe braking. Driver was only guiding steering at the time ( foot did not touch brake). The dual lane highway was level and straight. There were no other vehicles in sight. The skys were overcast so there were no shadows. There were no overpasses. I have had this happen several times when autopilot is engaged but never when just cruise control activated. Sudden braking like this at high speeds could cause a vehicle following this auto to rear end that could cause the loss of control of this vehicle that would cause a life threatening event to occur.

The optional "Self Driving Option" we purchased for an additional $8,000 when we purchased this vehicle has never worked properly. The adaptive cruise control will brake for no reason, often multiple times per mile. It seems to be affected by shadows on the road and the vehicle mistakes these shadows for obstacles. The "Self Driving Option" will abruptly jerk the steering wheel in the direction of oncoming traffic and violently disengage. My wife and I find it to be unusable. Multiple service requests to Tesla have resulted in no actions.

The optional "Self Driving Option" we purchased for an additional $8,000 when we purchased this vehicle has never worked properly. The adaptive cruise control will brake for no reason, often multiple times per mile. It seems to be affected by shadows on the road and the vehicle mistakes these shadows for obstacles. The "Self Driving Option" will abruptly jerk the steering wheel in the direction of oncoming traffic and violently disengage. My wife and I find it to be unusable. Multiple service requests to Tesla have resulted in no actions.

The recent full self driving update that was received approximately one week ago has resulted numerous, substantial, and dangerous Self driving errors. The Vehicle struggles greatly to understand lanes and has on multiple occasions suddenly and without warning jerked the wheel to completely change lanes and then re-jerking the wheel to change back into the Original Lane. There has also been a shocking increase in phantom breaking while driving at highway speeds which is unsafe because other nearby drivers may slam on the brakes. The behavior of the vehicle has a times been so erratic that I could’ve gotten a ticket from an officer. Finally, the vehicle increasingly does not understand lanes and has several times veered into a left turn lane despite having a follow vehicle and despite being on a navigational Straight path, subsequently the vehicle then suddenly jerks the wheel back into the correct lane. This all happens very quickly and is not preventable by the driver even when hands are on the wheel and the driver is fully alert. I love my Tesla car. It is the safest car in the world. However, I feel very strongly that the company has been negligent and has definitely not been safety testing updates appropriately before wide release. I strongly recommend that guidelines be put in place to require Tesla to publicly report the number of FSD disengagement‘s every week. I also feel strongly that Tesla needs to permit drivers to roll back software to a prior version of full self driving. In addition, in order to send a video directly to Tesla regarding self driving errors the driver presses a video icon; however, this prevents the driver from storing the video and sends the video directly to Tesla. Therefore, drivers have to make a decision between documenting the dangerous error for themselves or to contribute to fleet learning. Each time videos pressed video must be saved to the usb drive too.

On June 1, 2022, we left on a roadtrip to CA from UT. Our Model 3 kept having incidents of "phantom braking," in which the Traffic-Aware Cruise Control and Autopilot systems would suddenly, inexplicably cause the car to slam on the brakes, and sometimes even flash a "red" steering wheel and an alarm with a warning that there was an object ahead —when there was NOT! This happened at least a dozen times en route on Highway 95 in Nevada, and continued to happen throughout our roadtrip on other highways until we returned home one week later on June 8, 2022. I have experienced this problem several times over the past year, and numerous other owners have already submitted similar complaints to NHTSA. Indeed, the TACC and AP behaviors are now significantly WORSE than when we first took delivery of the car over 4 years ago in April 2018. It is as though the car suffers hiccups, spasms, Tourette's Syndrome without any warning. I fear that one of these times we will be rear ended by a car behind or to the side of us. I can only speculate as to why this has started to happen, but suspect it is because Tesla decided to stop using its radar sensors a year ago and now only relies on its cameras. These incidents truly frighten my wife to death, so much so that she wants me to get rid of the car. I can't say I blame her, as the problems with the car's TACC and AP systems are now making it unsafe on our highways. If Tesla doesn't restore reliable, dependable, safe TACC and AP in the near future, I will get rid of the car.

I was driving on a one way street when the car suddenly stopped. I was not at an or close to an intersection. There was a pedestrian waiting on the side of the road, standing between cars. He was not in my way. He was not even close to the vehicle. The car sounded audible warning and came to a complete stop. I believe this was the reason the vehicle stopped. This is the 2nd time since my 3 year ownership that this has happened. I provided Tesla with time stamps of the event during my service visit. They told me this is normal function of the vehicle. Just reporting this in case there is a more serious underlying issue that warrants additional investigation.

Our model 3 was purchased with Tesla’s “full self driving (FSD)” software installed in 2018. Throughout our entire ownership period, whenever FSD is active, there are specific locations known to us - mostly at certain points on freeways - where the car will “phantom brake,” in other words suddenly decelerate the vehicle very rapidly and require *immediate* driver intervention. For instance, there is a freeway interchange ramp that passes under a bridge and doglegs to the left. The car will always phantom brake about 200 feet before it reaches the bridge. This has been happening for years, and we’ve reported this defect and this specific location to Tesla many times. There are other locations known to us as consistent phantom brake triggers, but there are of course times where this occurs when we are not expecting it as well, and that’s when it’s most dangerous. We believe it may have something to do with the car’s sensors when they sense certain shapes or objects while the road is also curving slightly, as this is the most common phantom brake scenario for us. Again, this has been happening since we purchased the car in 2018. It occurs randomly at least a few times a month, and it *always* occurs in certain locations.

I was using Enhanced Autopilot on Tesla Model 3. It breaks automatically in middle of road for no reason even when there is no object in front of it. Its a life threatening situation because the vehicle behind my car will not have enough breaking distance and time at high speeds. It happens almost every month and specially under the reflection of bridges. I complained to service center and employees just ask exact time when it occurred and if exact time is not provided than Tesla employees does not do anything to resolve the issue. Looks like Tesla is putting many lives in danger.

I received access to Tesla’s Full Self-Driving system in late 2021. In the lead-up to that access, Tesla used a series of driver scoring metrics to select which users would get access first. Consistently, my metrics for forward collision warnings would show as alarmingly high, despite never coming within remote striking distance of another vehicle. On more than one occasion, a vehicle passing in other lane or turning left but in the other lane tripped the warning. At the time this registered as a red flag but more a bug of the evaluation system than the car’s recognition software. As time with the FSD suite has gone on, and subsequently with every new update, the phantom braking problem a number of users have described has plagued my experiences. Numerous times I’ve been driving with FSD engaged on two lane roads with no cars, shadows, animals or distractions of any kind around only for the car to suddenly and rapidly decelerate. Additionally I’ve received warnings repeatedly, without explanation, that the emergency braking system is disabling itself, then the warning will clear without any indication it’s either become reactive or is still disabled. Further, I’ve noticed through the new blind spot camera feature Tesla has released that my left rear-facing repeater camera can be blinded by the flashing of the embedded turn signal in the housing - but only the left signal, the right is not. This has led to, on more than one occasion, FSD disabling itself while active with little or no warning. I’ve listed the approximate date the first phantom braking occurred, but all of these problems have been an ongoing issues for months.

When driving on local roads and the interstate the card suddenly brakes for no reason when using auto pilot or full self driving. Sometimes it seems to be triggered by shadows from trees or other objects on the road and other times for no reason at all. I have been going 45 mph and the car suddenly braked to 30mph. I have been on the open interstate doing 70 mph when the car will suddenly and violently brake when there is a car on your bumper and this is very dangerous. If you dont keep your foot over the gas while driving and force the car to speed up it will cause an accident bc it will brake until the car is stopped probably. Somone needs to look into tesla and the phantom braking on auto pilot and full self driving. i have owned this car for almost 4 years and over the last 1 year this has gotten progressivley worse when they switched from using the radar sensor in the front to camera only vision called tesla vision. it is unsafe and im sure it's causing accidents today and needs to be investigated since Tesla cant seem to fix it.

NHTSA forced Tesla FSDBETA to remove “Rolling Stop” behavior at clear intersections. This has caused me to be continually honked at, drivers aggressively passing my slow FSDBETA car. The decision by the NHTSA has caused my car to be more UNSAFE by impeding proper traffic flows. NHTSA should be focused on improving safety and not traffic law enforcement. This complaint is directed at the improper decision and solely on the NHTSA to lift the guidance to Tesla. As a customer I now feel my car is unsafe to drive due to your decision.

Multiple episodes of phantom breaking with the car on cruise control on the highway. The car was not on autopilot during the episodes. The car abruptly drops from highway speed with full braking until you can override it with the accelerator. This will cause accidents of someone is close behind you. As a result, I do not use cruise control.

Twice the car in Autopilot braked for no apparent reason. First time on an Interstate traveling at 65 mph in the center lane. As I was about to pass a truck located in the right lane that was going very slowly with its blinkers on, the Tesla abruptly decelerated from 65 mph to about 40 mph. Thankfully there were no cars behind me because I would have been rear ended. The second incident happened on a road inside my community that winds through a golf course. I put the car on Autopilot at 30 mph speed limit because there is radar hiding every. day. The car suddenly braked for no apparent reason . My hypothesis is there was a sign close to the road warning that golf carts cross here. There were no golf carts or people nearby and perhaps the sign was seen by the Autopilot as an object to stop the car.

The automatic emergency braking system activated when there was no collision imminent. (7:13am, 5/22/22) Neither cruise control nor autopilot was engaged at the time of incident. I was nearly hit from behind by a driver who did not expect me to stop as there was no hazard or other vehicle. Tesla inspected the vehicle and found no fault and claimed that I needed driver education. Also on a subsequent interstate trip with cruise control engaged, the automatic emergency braking system activated unnecessarily. It appears to be related to shadows on the road or pavement changes.

When driving on undivided highways, the car will phantom / panic brake due to oncoming cars approaching in the opposite lane. At times, the car phantom brakes for no apparent reason at all as there are no cars nearby. At night, it gets much worse, with the car phantom/panic braking at nearly every oncoming car. My 2018 Model 3 is equipped with radar-assisted Autopilot, but newer Tesla vehicles don't have the radar hardware at all and instead rely on a vision-only system that uses the cameras alone. When I opted into Tesla's Full Self Driving beta, the new software disabled my car's radar and my car became a "vision-only" vehicle, like newer Tesla vehicles. At this point, phantom / panic braking became significantly worse. When radar was used, the braking was rare but still unsettling. With vision-only Autopilot, it's nearly unusable. Even with basic cruise control, phantom / panic brakes happen with the same frequency as if you're using Autopilot. I basically can't use any cruise control or autopilot when driving on undivided highways. On interstates and in-city highways, phantom / panic braking does still happen, but it's less frequent.

Phantom braking, i.e. apparent engagement of brakes on car for no apparent reason during routine driving

Multiple instances of phantom braking and slow down while driving on Traffic Aware Cruise Control (TACC) and/or Autosteer mode of the Autopilot feature. In addition, the lane keeping assistance feature gives phantom warnings even though the car stays in the lane.

I saw the reports on all the auto breaking issues with tesla, and i wanted to report for over a year my car does this ALL the time when auto pilot is engaged. I can remember hundreds of times where there is nothing around and all of a sudden the car auto breaks and its hard breaking as though im slamming on the breaks.

Driving while on cruise control, the car will phantom brake. That is, it will apply the brakes: - when a vehicle is way way out there in my lane and not a potential problem. - when two vehicle are close on each left and right side lanes, but not in my lane. For instance, when on 3 lane road with all lanes going the same way, vehicles on my left and right sides out in front of me but not in front of me, the car will suddenly apply the brakes. These are just the most common instances. I get lots on incidents of the vehicle unnecessarily applying the brakes when on cruise control.

I intermittently get an on-screen message “automatic emergency braking is disabled.” Adaptive cruise control and auto-steering are disabled and I am unable to engage either one. Randomly the problem will resolve itself with no intervention from me - usually a day or two later. I have taken the car to Tesla service twice and they are unable to resolve the issue. On the last visit the service technician said that it is a firmware issue.

Car slammed on brakes as we were overtaking truck. Car may have mistaken truck's shadow for an object; this was around noon on a clear sunny day. Braking was sharp enough to cause an accident had someone been following us closely.

Stopped in left turn lane. On green light car in front and I began our left turn. I was some distance behind the car when suddenly my brakes applied automatically and I came to complete stop. Luckily car behind did not rear end me. Also, my car started beeping and a warning said something to effect: automatic emergency brake activated.

While vehicle was engaged in autopilot and adaptive cruise control on the freeway in traffic it has intermittently accelerated toward the vehicle in front requiring the driver to abruptly manually press on brakes to disengage the adaptive cruise control in order to avoid colliding into the vehicle in front. It has also suddenly braked on the freeway when there was no object in front requiring the vehicles behind to abruptly slow in order to avoid collision to rear of the vehicle. This has happened multiple times over years. I did report it once to the manufacturer who could not explain or reproduce it. There were not warning messages or lights to demonstrate failure of the system.

My 2018 Tesla Model 3 failed to engage its automatic emergency braking system - resulting in a collision due to the vehicle in front of me suddenly braking.

The auto cruise control brakes hard suddenly for no reason !! This puts the car in danger from vehicles behind me as the very unexpected slow down. Also, the blind spot warning has no audible and the car in next lane is too close beforeit turns red on the scree. It's not safe to turn your viewing to the screen from the road to change lanes. I drive the old fashioned way to be safe by looking over my shoulder before changing lanes.

Sudden Unintended Acceleration: While pulling forward onto our driveway (with incline) at a very slow speed, the car suddenly accelerated and brake was not working. Automatic emergency braking also failed.

My Model 3 regularly brakes at highway speeds for no reason it does this in daylight but more frequently at night also - it appears more common in the rain - where reflections off the wet pavement seems to appear as solid objects to the cruise control i have stopped using the cruise control now - it is frightening to have the car suddenly slam on the brakes at highway speeds

My car is equipped with forward-facing radar, but ever since Tesla turned it off in favor of "Tesla Vision" my Autopilot/TACC experience has been greatly worsened. The car suddenly (and very unsettlingly) slams on the brakes on the highway or city traffic (I have FSD Beta) for anything from shadows, to hills/inclines, to curves, or minor harmless debris (shopping bags) in the road. This has not yet caused an accident but has almost come close. Other issues: - FSD Beta, when engaged, forces the computer to have control over the high-beams and windshield wipers. The car obsessively flashes the high beams whenever possible, including on well-lit city streets. On multiple occasions this has triggered road rage in surrounding drivers because they think I'm flashing my brights at them for no reason. There is no reason to engage the brights in a well-lit urban environment. - Forward Collision Warning has become completely unreliable and routinely warns for cars that are not in my lane or in front of my car directly. This makes me more likely to just ignore the warning.

While on adaptive cruise control, my car breaks on highway for no reason. Looks like it happens at certain parts of highways. I noticed this at at least 3 highways and it breaks unexpectedly causing the vehicles behind me to almost crash into me.

regularly experience phantom breaking and unwarranted early collision warnings

The car has repeatedly (but not often) initiated emergency braking while traveling on a freeway. It has done this in literally the same place on California highway 85 several times, and occasionally on other freeways. It has always been a clear, sunny day, and it seems to occur when the vehicle travels from deep shade into bright sun (i.e. as when going under an overpass). The road was straight with no vehicle directly ahead for several hundred feet. I have reported this to Tesla via the app. and through the service departments. I have included date and time as well as location on some occasions. The only comment I have received was that the logs showed no problems, and no further action was taken by Tesla. When the severe braking occurred, an alarm went off in the car (a beeping sound). At least once a following car nearly collided with me. I was probably traveling in the range of 68-73 MPH. I do not have dates or mileage information, but Tesla may based on the occurrences I reported.

Everyday while I am driving on the highway, when the car is in cruise control, multiple times it decreases the speed drastically for no reason.

"PHANTOM BRAKING" when cruise control is on, usually when on the freeway. Sometimes it occurs next to other vehicles, sometimes there are no cars around. On a 600 mile trip it will often occur at least once and most of the time 2-3 times. If it was slippery, the sudden braking could cause loss of traction. If someone was too close behind me they could rear-end me. No one has inspected the issue. Has been occurring since I've owned the car. No warnings.

While traveling from San Diego, CA to Louisiana on the self-drive mode the car abruptly stopped in traffic 3 times (while this was at night there was no concern for an accident). On the return trip back home it did it 1 more time in the daylight hours, but this time there was an 18 wheeler behind me. We were doing the speed limit at the time, which was 75mph and it slammed on the brakes making me go from 75 mph to 60 in seconds. I was able to take control of the vehicle and get it back to highway speed before there was an accident.

On several occasions while driving with autopilot on the car has suddenly and inexplicably braked HARD while at highway speed. Each time there was nothing in the road, no car, no obstruction, no anything, but it was as if the car saw something that wasn't there and jammed on the brakes. I quickly took back over and returned to highway speed. Luckily we were not in heavy traffic or I would have been concerned about being rear-ended by another vehicle. I don't do a lot of road trips with the car and have used autopilot less as a result, but I would guess it has happened 4-6 times since I have owned the vehicle. I just thought it was a glitch that they would work out but just saw reports of others still experiencing this issue so thought I should report it so you were aware of the breadth of the problem. The date below is a total guess as to the last occurrence.

Since we purchased this car 3 years ago, when driving with the cruise control, it has in appropriately applied the brakes. This is a ongoing problem. This is a frequent occurrence (once or twice during 100 mile drives) mostly on 4 lane high ways. The most common situation where this happens is on a uphill rise in the highway and a overpass at the top of the hill. It can be a slight application of brake or a very strong application which is very dangerous with a large truck or close following car behind you. I only use cruise control to rest my foot on long rides and turn it off when approaching a over pass. There are other times it is turned on when a truck passes on the other lane or a car entering the high way from an entrance ramp that the white lines are worn out. We only use the cruise control with great care.

The software on the car is and has always been updated to the latest standard. Driving on east and westbound on US 60 near Phoenix and Mesa AZ the car will emergency brake from time to time. This condition has continued for years off and on and is still happening as of this week. Generally speaking it appears to be caused by shadows from the overpasses and is far more prevalent at low sun angles that create significant shadows leading up to those overpasses.. I don't recall it happening after dark. On several occasions I have submitted "bug" reports via Tesla's online automated system.

I don't recall it happening after dark. On several occasions I have submitted "bug" reports via Tesla's online automated system.

The car breaks automatically when neighboring cars drive by during autopilot. I have a family of 4. This appears to happen when using autopilot almost every single time. It has gotten worse over the years. This car is becoming dangerous.

While using Autopilot adaptive cruise control at speeds of 50-70 mph, the car suddenly applies the brakes even though there is no car or other hazard anywhere near the car. This phantom braking has been happening since I bought the car in 2018. I imagine it's a software problem. I read recently that NHTSA is investigating a similar problem on 2021 and 2022 Tesla Model 3s, so wanted to let you know that this problem is also affecting my 2018 model. Also I read that there's speculation that the problem was as a result of a software update over the past year, but in my vehicle the phantom braking has occurred since 2018. The problem most recently happened last week.

I read in the news that you are investigating phantom braking in cars without radar. I want to make sure you are aware that this is also affecting cars with radar. Each software update makes it worse as they seem to use the radar less and less.

The car has been suddenly slowing from 70miles/hr to 50 miles/hr on the highway when on autopilot. I’ve been noticing this for about 6 months

Tesla FSD beta/ autopilot has frequent phantom braking. Sometimes for oncoming traffic in opposing lane or because of parked cars or even a shadow or nothing at all. It’s dangerous especially when it slams on the brakes so hard items in car will fly to the front. Could cause rear end collision or startle driver and cause them to react poorly. I have been doing bug reports and sending emails to Tesla FSD beta team since 11/2021 after each new update and it has never been resolved even remotely to an acceptable safe feeling product for use.

I drive along the highway and all of a sudden while I'm in adaptive cruise control my car brakes suddenly for no reason.

On multiple occasions while my car was in Autopilot mode on highways and at highway speeds, I have experienced rapid braking (phantom braking) when there was no apparent reason for such. All of the phantom braking events have occurred on sunny days, usually around mid-day. Most often, the events have occurred when approaching a bridge or overpass. My supposition is that the system is mistaking dark shadows under bridges as obstacles that need to be avoided. As a result of the frequency of these events, I no longer use the system on sunny days.

1. Phantom Breaking when on Adaptive Cruise Control. 2. Many times , unexpectedly there will sudden application of brakes, or slowing down of car when on highway and with speed in range of 55-65 mph. 3. Mostly this happens when big truck comes in front or passing thru a bridge. 4. Many times I am not able make any reason of this sudden brakes. 5. Many times due to sudden deacceleration , I have a car following in back, came very close , and honking.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving at highway speeds with the vehicle in auto pilot mode, the vehicle would erroneously reduce speed and on occasions nearly come to a complete stop. On one occasion while driving approximately 70 MPH, the speed was suddenly reduced to 10 MPH. The cause of the failure was not determined. The manufacturer was notified of the failure but no assistance was offered. The local dealer was not contacted. The failure mileage was 5,000.

Mileage: 5,000

The contact owns a 2018 Tesla Model 3. The contact stated while driving at 60 MPH with the cruise control activated, the vehicle inadvertently decelerated to 40 MPH. There was no warning light illuminated. The accelerator pedal was depressed and the vehicle responded and accelerated as needed. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer however, the mechanic was unable to determine the cause of the failure. The dealer also informed the contact that the failure was a known issue and that the manufacturer had been made aware of the issue. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 14,484.

Mileage: 14,484

On several occasions, with Autopilot engaged my 2018 Tesla Model 3 has strongly applied the brakes while traveling at highway speeds, despite the fact that there were no obstacles up ahead. This has occurred throughout my ownership of the vehicle, and in each instance, it has been extremely unsettling. It required me taking manual control of the vehicle in order to return to highway speed. I do believe that on these occasions my safety and that of my passengers and other motorists has been at risk. It is worth noting that each time this has occurred there has been an overpass up ahead. I have hypothesized that the Autopilot interprets either the overpass or the shadow cast by the overpass as an obstruction. In my experience there is an apparent correlation here that is worth exploring. I was motived to report my experience after reading today's NY Times article (2/17/2022) about "phantom braking". The article indicates that you are "focusing on Tesla Model 3 compact sedans and Model Y hatchbacks that were made in 2021 and 2022 and sold in the United States." Based upon my experience, you may need to you broaden your inquiry to include other model years.

As others have reported, please add my 2018 Model 3 to the list of reports of the vehicle having constant phantom breaking issues that Telsa needs to address. I'm glad you are conducting this investigation. Most times phantom breaking occurs I submit a "Bug Report" using the voice button in the car that sends car logs directly to Tesla so they will have records of these phantom breaking issues at the exact time and location my car experienced it. While it is random it also is very predicable at certain spots on highways I drive in the Bay Area. Namely 680 South in the HOV lane right before the Mission Blvd. exit. At least 90% of the time even I'm the only car in that stretch of road the car breaks hard for no reason. It is occurs so often in that section that I typically disconnect the Advanced Cruise Control in sections as well as other section of the Bay Area where phantom breaking consistently occurs. Two of my neighbors also have M3's and we have compared notes and we all typically see phantom breaking occur in similar areas in the Bay Area.

My 2018 Tesla model 3 experiences “PHANTOM BRAKING” specifically and repeatedly traveling eastbound on the Loop 202 approaching 32nd street in Phoenix AZ. I have reported this issue to Tesla with no resolution.

While driving to work, in 2021, I had experienced sudden deceleration and disengagement of the autopilot. It happened a few times. I have ignored it thinking it to be an electronic glitch. I did not know how to report to Tesla. But since I was sharing my data with them, I thought they will pick up some issue and alert me if there is really something malfunctioning. But I just found out that other customers has had similar issues and that I could report it to NHTSA, therefore I am reporting it albeit delayed.

Car constantly phantom braking seemingly because of oncoming traffic safely in their own lane.

When driving on autopilot on highways phantom breaking occurs for no reason. There are no warnings, the car just slams on the brakes. Elon Musk has state they were removing radars from cars to eliminate this issue and disabling it in cars with that hardware, but since my car have gone to all vision it is much worse. While following vehicles should always follow at a safe distance to prevent collisions, the reality is most drivers follow too closely and this could very easily result in a rear end collision. It could also trigger road rage from following drivers assuming the driver is doing a brake check on them. This has occurred numerous times over various software versions, but its much worse with the pure vision version of autopilot. Current software is 2021.44.30.5

Was on highway using full self-driving feature when my car suddenly braked hard and in other instances I received a forward collision warning to take immediate action. These incidences (1/17/2022 & 2/6/2022) occurred when no cars were in front of me. I do not feel safe using this feature.

While using Tesla autopilot on surface streets, the car will randomly brake. Additionally, it frequently thinks that green lights are red and will stop the car at an intersection which can cause an accident as other cars will not be stopping.

When I use auto pilot on freeways, the car will suddenly brake, when there are no vehicles or obstructions in front of me. The sudden reduction in speed is jarring, as I fear getting rear-ended. This "phantom breaking" has happened on numerous occasions, to the point that I do not use auto pilot when I have other passengers in the car.

Many times when I am driving using the adaptive speed control the vehicle will suddenly brake very hard, slamming on the brake, scaring the driver and all passengers in the car. When this happens, there were no other vehicles near our vehicle at the time. If another car was behind mine at this time,I feel that it would surely have caused an accident. I have documented these occurrences each time and brought to the attention of Tesla Service department.

When using autopilot on the freeway there are multiple incidents where the brakes are aggressively applied for no apparent reason

I drive twice a week from Washington DC to Charlottesville, VA, a distance of 117 miles each way. 35 miles are on an interstate and 82 miles are on a divided 4-lane state road. Since I restarted this commute in September 2021 after Covid shutdowns and summer break, I have experienced recurring, frequent problems with the car's vehicle warning system, adaptive cruise control, and forward collision notification system. When I drive on the interstate (where there is currently a great deal of construction), the adaptive cruise control keeps automatically adjusting my speed when there is no speed limit change. So I might be traveling at 65 mph when my speed is suddenly lowered to 30 mph. There are no warnings, either visual or audio. The speed just changes. This is incredibly dangerous and requires me to be hyper-vigilant to avoid a rear end collision, or to turn off the cruise control system. When I travel on the state road, I receive frequent visual notifications of a collision risk ahead of me. I received four of them yesterday, and there was nothing in front of me at all. But sometimes, all automated systems disengage, a visual warning appears on my vehicle screen, and a loud klaxon sounds. This happened twice yesterday. It often occurs when I'm driving on a hilly stretch of road, when I'm ascending towards a crest in the roadway. It happens more at night than in daylight, but it happens without warning under a variety of conditions. The car also has an automatic lane change feature, which used to work reliably, but now seems more capricious, for no apparent reason. I engage the system, the screen shows it's safe to change lanes, the vehicle initiates the lane change, and then the car suddenly lurches back into the lane I'm leaving, saying the function isn't available. This has happened in all traffic conditions, from an empty highway to one with moderate traffic. I don't use the system when there's a lot of traffic.

Car randomly brakes very hard when using driver assistance systems. This has happened on wide open roads on clear days, multiple times.

Tesla introduced blind spot camera availability with the release of Version 11 software. When the driver switches lanes while in autopilot by engaging the turn signal stock at night, the built in turn signal led above the repeater camera blinds the camera by washing out and degrading the camera picture as the turn signal led turns on and off. This has been remedied in newer model year cars as shown in the following youtube video-- https://youtu.be/_BUPsjguqdY This is a safety hazard to vehicle occupants as well as the driver of the vehicle as the repeater camera is being blinded by the turn signal led.

When the vehicle is in autopilot, it sometimes (once every couple of months or so) will suddenly engage automatic braking as though there is an obstacle detected in front of the vehicle. In nearly every instance, this has happened at one particular location on an interstate where an overpass casts a shadow on the interstate on which the vehicle is located. The problem seems to be that the vehicle senses an object in front of it and the collision avoidance system is engaged; however, that "object" is only a shadow. This has happened in a few other locations (not simply this where this one overpass is).

I have been plagued with Tesla’s phantom braking for *years*. For all that they do, this seems like a problem they are not willing to invest enough resources to combat the problem. Some releases have been better than others but for last batch of releases, it has gotten far worse than ever before. The car is afraid of bridges and slows down unreasonably. The car is afraid of overhead signs (carpool ones especially) The car is afraid of cars riding on or near the lines of an adjacent lane. The car is afraid of oncoming traffic on the left while driving. What is ironic is these events of aggressive braking is all for nothing. 90% of the time,. The car brakes and does drama without actually having enough time or space if what it was afraid of actually happened. The car has a rear facing camera - why can’t it adjust behavior based on tail gating? Would the car rather have a rear end collision or be afraid of a bridge? It is straight dangerous. The fact there aren’t a lot more accidents is auto pilot/fsd drivers be a large majority pay attention. But, I have had close calls and *many* angry drivers around me get frustrated when it happens. It’s been happening for 4 years…. I realize navigating a complex intersection is a tough problem to solve. They have prioritized this over the fundamentals of driving in a sane way on the freeway in a straight line. It’s ridiculous and I for one am very tired of this problem lasting so long. What chides me is that, “car, why are you braking when a car right in front of you magically went through the bridge you are afraid of?” It is basic logic and simple/obvious clues to help avoid this. They choose not to use it. Also - being in technology myself, I have to rake Elon over the coals. No one smart chooses to not use available data. Elon calling ultrasonic data to be ‘noise’ to turn to vision only is a sign of great hubris over being pragmatic. His ego regarding Lidar is a problem.

1) What component or system failed or malfunctioned, and is it available for inspection upon request? answers: the automatic emergency braking system was incorrectly activated on several occasions, yes 2) How was your safety or the safety of others put at risk? answer: my Tesla braked unexpectedly in the driveway of my home 3) Has the problem been reproduced or confirmed by a dealer or independent service center? answer: no 4) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? answer: no 5) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? answer: no

Car rear ended, brakes froze after reacting to a car in front of me. Behavior unexpected and Tesla should not have frozen break maybe Abs kicked in

When driving with the driver assist Auto Pilot active it's possible to disengage Auto Pilot but Traffic Aware Cruise Control (TACC) remains active. When Auto Pilot is active the auto pilot system has control of the car including navigation, maintaining the lane, and speed. Speed can be set by the car or driver. In some cases disengaging auto pilot disables TACC , in other cased TACC remains active. A driver may be caught off-guard when the car continues forward at the set speed after disengaging auto pilot. This difference in behavior can surprise a driver and that puts every other driver in the area at risk. Ways to disengage Auto Pilot : 1) Press up on the right-side stalk (also used to engage TACC & Auto Pilot) on the steering column behind the steering wheel. When pressing up on the stalk Auto Pilot and TACC are both disabled. 2) Step on the brake pedal. Pressing the brake pedal disables both Auto Pilot and TACC. 3) Turn the steering wheel, for example to avoid a road hazard or a vehicle in the car's path. Turning the steering wheel only disables Auto Pilot functions, TACC remains active. The car continues to move forward at the speed Auto Pilot was using. The three disengagement methods have similar, but different outcomes. The result is a driver by moving the steering wheel can disengage Auto Pilot while cruise control remains active. This problem is compounded when considering Tesla's forward collision warning and avoidance has issues with stationary vehicles like those stopped at off ramp traffic lights or in traffic jams (this will be covered in another report). Since cruise control remains active when Auto Pilot is disengaged by turning the steering wheel is as designed there are no warnings or alerts. Several time I've had to swerve or slam the brakes to avoid contact with other cars and trucks after taking control with the steering wheel while Auto Pilot was active. This happened several times, date listed in Additional Details is near first time.

Several times I am driving on the Highway at 65 mph and the car decelerates rapidly for no reason while I am in the drive assist mode. I have reported this several times to Tesla through the "report bug" feature in the car. It's very scary and dangerous. Additionally the drive assist mode doesn't work well in dense fog or rain and there should be a warning to that effect.

Over the last several weeks there have been numerous phantom braking events when on autopilot. These seemingly happen out of nowhere, various conditions, and for no apparent reason. Some of the braking events are very light and others are harder. I estimate in the last 4-6 weeks I have 2-3 per week while commuting. One almost caused the person behind me to rear end me. I am on software version 2021.32.22 on a 2018 Model 3

Multiple "phantom braking" events while using Tesla's Auto Pilot system. Vehicle, while in Auto Pilot mode, will suddenly aggressively brake for no reason (no road hazards or other imminent dangers). Occurs about once every 50 miles driven with Auto Pilot on. The last incident occurred on 11/14/21

I was driving on interstate, using adaptive speed control but not autopilot. Middle lane. Car suddenly applied brakes. A car was ahead of me but not very close, there was no reason to apply brakes. Slowed down from 65 to 45 very fast, (seatbelt tightened) before I resumed acceleration myself. Lucky I wasn’t rear ended because traffic is usually heavy in that area. I had one passenger who was as surprised as I was. Yes, the car can be inspected. Not reported to Tesla. No warning messages, including didn’t make the loud sound Tesla makes with normal city driving if a car ahead is turning right and I start to accelerate before it has completely left the lane I am in. Tesla cameras are also not seeing cars traveling in my driver side blind spot. They used to show up on the screen but haven’t for months. Tesla cameras also do not see low flat bed trailers (such as empty car carriers) pulled by pickup trucks, common in Ohio. Screen shows the truck but does not show the trailer. I don’t use autopilot because of the blind spot issue, now I’m afraid to use cruise control too.

On enhanced auto pilot highway speeds, the vehicle suddenly breaks, also known as phantom breaking. Extremely dangerous! Tesla service notified, their response “software is in beta, with a recent software update addressing the matter”. 35,000 of driver miles experienced, the auto pilot is extremely glitchy. When the algorithm is to complicated the vehicle well transfer the liability back to the operator with little warning. Their vehicle safety claims are highly overstated. Software updates cannot keep up with outdated hardware.

The Tesla Model 3 manual is unclear on what situations it is appropriate to use various ADAS functions of the car. For instance, on page 86, it says to never use autosteer on city streets or construction zones. Then on page 87 it says "if you choose to use it on residential roads" which should never be acceptable. Then, on page 94, it discusses the use of Traffic Light and Stop Sign control, and how the vehicle will detect and stop for these controls when using autosteer. These are controls which only exist on city streets. It is impossible to utilize this advertised feature while obeying the manual's other limitations. The same conflicts exist in areas such as page 87, where it first says that the vehicle may steer out of a lane to avoid an object, but then immediately warns that that the car will not do this in the very next paragraph. Page 93 warns you to "be ready to assist" as approaching construction zones, not to disable AP like the warning on page 86 requires. With inconsistencies in the manual such as these, it is expected that a user would be confused as to what the capabilities and limitations of the system are, posing a safety hazard. Additionally, the vehicle is capable of enforcing these warnings itself. As described on page 87, the vehicle is aware of the road type it is currently on. Rather than expecting the user to not use it on prohibited city streets, the system should enforce this limitation if it is one the manufacturer actually expects the user to obey.

Within the first day, my 2018 Tesla Model 3 lost all instruments, safety indicators, and touchscreen controls while driving on the freeway. The car did this *multiple* times, without warning. Each incident lasted several minutes. It was alarming, and there was no way to tell what systems in the car were working (such as automatic emergency braking or cruise control), and no way to change settings, or even know if the turn signals were working as I tried to exit the highway. The Model 3 has only one screen where everything (including basic instruments) is displayed and most controls are accessed. When the screen freezes, we lose access to basics like speedometer, collision safety or system failure warnings or even speedometer readings, as well as control of headlights, wipers, climate control, lock / unlock, navigation, and many other essential functions. During these failures, we do not know what if any safety systems are still operating. Typically when this problem occurs, the screen "freezes" while driving, without warning or any indication of trouble. The screen remains unresponsive for a lengthy period (typically minutes) until the screen goes completely black for a time, and then eventually a Tesla logo appears, followed by instruments and controls gradually being restored. The car was delivered from the factory to my home in this state, with other obvious defects—Tesla did not permit us to test-drive it. The next night a Tesla technician saw the failure happening in real time, through Tesla's remote diagnostics. He said the car was probably not safe to drive. I asked to return the car under Tesla's satisfaction policy, and he agreed to start the refund process. Tesla refused to take the car back, and the car has continued to exhibit these failures. This has been happening since the car was delivered in October of 2018.

I bought the standard autopilot for 2 model 3sI find it highly useful. It keeps me in the middle of my lane. Warns me with loud signal and bright red car marking of cars in my blind spot if it is dangerous to change lanes. Allows me to see clearly all cars around me. It will not allow me to drive without my hands putting active pressure on the steering wheel. I feel that it makes driving much much safer. Driver still needs to pay attention with active pressure on steering wheel.I drive 30,000 miles per year. I paid $3000 extra to buy the autopilot after not having it for the first 6 months. It was well worth the cost.Should be a standard feature on all new cars!!! My wife who drives my other model 3 has had the same experience.

WHILE DRIVING MAJOR FEDERAL FREEWAYS (I65 & I85) BETWEEN HOUSTON AND N.C., THE CAR WHILE ON AUTOPILOT AND TRAVELING AT FREEWAY SPEED (70 MPH) WOULD EMERGENCY BRAKE WHEN APPROACHING SOME (6-7 TIMES) OVERPASSES APPARENTLY THINKING THE OVERPASS WAS CROSSING TRAFFIC OR A FORWARD OBSTRUCTION. THIS ALSO OCCURRED (3-4 TIMES) WHEN IT WAS SIMPLY A RISE IN THE FREEWAY AHEAD. THE BRAKING ONLY LASTED FOR MAXIMUM 1-2 SECONDS, BUT SINCE THE VEHICLES BEHIND ME WOULD NOT BE EXPECTING ME TO BRAKE, I CONSIDER THIS A SERIOUS SAFETY ISSUE.

I WAS IN BUMPER TO BUMPER TRAFFIC ON THE FREEWAY ABOUT TO CHANGE LANES. I WAS ON TOTALLY MANUAL OPERATION. THE CAR SUDDENLY ACCELERATED AND HIT A CAR AND CONTINUED WITH MY FOOT ON THE BRAKE TO HIT ANOTHER CAR. THERE WAS NO COLLISION DAMAGE WARNING OR AVOIDANCE AUTOMATICALLY STOPPING THE CAR.

WHILE DRIVING ON A HIGHWAY TESLA SUDDENLY HARD BRAKED OUT OF NOWHERE. MY SPEED DROPPED FROM 70 TO 30 IN A COUPLE OF SECONDS. THERE WAS AN 18 WHEELER BEHIND ME AND IT COULD HAVE BEEN A DEADLY COLLISION IF I HADN'T INTERVENED. THIS IS A KNOWN TESLA BUT THAT SOMEDAY WOULD KILL SOMEONE.

THREE SEPARATE PROBLEMS: (1) REAR CAMERA GOES BLACK WHEN BACKING UP. (2) FORWARD FACING CAMERA GIVES ERROR ON SCREEN "DRIVING VISUALIZATION TEMPORARILY DEGRADED" WHEN DRIVING. THIS HAPPENS ON ROAD AND FREEWAY. (3) SCREEN BECAME COMPLETELY UNRESPONSIVE TO INPUT. MAP DISPLAY WAS WORKING. FOLLOWING SOFTWARE RESET PROCEDURE FIXED THIS.
