Automatic Emergency Braking problems of the 2020 Tesla Model Y

On Tuesday, [xxx], around [xxx] returning home and in my driveway when the following happened. Pulling into the left side of the driveway because a utility van was parked on the right side of the driveway with the rear door and driver’s side door opened with no one in the vicinity. There was not enough room to go forward into the garage. I was almost at a complete stop with the intention of getting out of the car to shut the drivers side door. That was when the car sped up at full speed and turned to the right into the van and continued in the right direction into the garage. The car was headed to the right back corner of the garage smashing into paint cans, a freezer, sink and cabinets. I had no control over the car from the time the car sped up and smashed into the back of the garage and it all happened in a matter of a few seconds. The vehicle has been totaled by the insurance company. This incident was recorded in the vehicle’s computer. The police department was called the same day and a police officer came to the house to record the incident. The car was towed to gerber collision & glass, 10491 corkscrew commons dr. , estero, FL 33928, phone (239) 947-6050. The car computer system should have recorded the event. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The incident happened on October 23, 2023 at 3:02 pm. The car is being parked between two vehicles and the car triggered automatic emergency breaking, after the emergency breaking there were error on screen about “automatic emergency breaking unavailable, abs disabled and automatic vehicles hold disabled”. After seeing this error on screen the car did sudden uncontrolled acceleration which caused it to crash in to buildings. I have contacted Tesla to investigate this issue, provided error message and vedio recordings of the incident. After two months investigation, I have been told they did not find issue in the car and can’t go any further details to explain error on screen, sudden emergency stop and sudden acceleration on the car. The car has been deemed total by the insurance company. I would like to share my data with you so proper investigation can be done and prevent similar situation in future.

On a round trip from albuquerque, nm to tucson, az, we experienced 8-10 instances of phantom braking in our 2020 Tesla long-range Model Y. The occurrences happened when the car was in adaptive cruise control and lane keeping assistance. Highway speed was typically 75 mph, weather was sunny, and roads were clear. Overall, an unnerving experience!.

While driving in cruise control mode, not auto steer, and with no vehicle in or obvious obstruction in front, the brakes will be applied without warning (phantom braking). It has happened multiple time in the years of ownership. It has happened once or twice with a vehicle following resulting in near rear-end collision. In one case this resulted in the follower reacting with "road rage," passing with horns blaring and braking in front of my vehicle. I have this recent incident on video as it just requires me to honk the horn and the last 5-10 minutes of driving is recorded.

We’re getting errors for traction control, reduced traction, control, disabled automatic emergency, braking is unavailable, abs disabled. This is a manufactures defect, and Tesla is requiring us to pay.

While driving on interstate highways and using autopilot, the car would "phantom brake" unnecessarily in numerous instances. Once it caused a truck to swerve dangerously to the next lane when the car suddenly brake in front of the truck. Mirages and sudden dips on interstate highways seem to be one of the main factors, but other incidents were less obvious what the cause was.

At least 5 times in the last month, my Tesla Model Y will suddenly brake when there’s no obstacle in the way. This most often happens at highway speeds, a terrifying scenario. I believe it mostly (or exclusively happens) when I have cruise control on. I notice it happens when there’s a sudden change in the color of the road surface, like going from concrete to asphalt. It also happens when I’m cresting a hill - like it can’t see over the other side of the hill. I have not yet experienced it while having the “stay in the lane” feature, which also sets the maximum speed at 5mph over the speed limit. But it definitely happens when I have cruise control on. I have only had this problem for the past few months, so I wonder if there’s a bug in the most recent software version.

While driving cross-country on interstates, I've experienced multiple sudden braking incidents. Incidents occurred every day of a 3-day journey (so far). All have occurred between 12:00-14:00 local time on sunny days, dry roads, with no cars or other obstructions in front of the car--in some cases, with no cars in sight at all. Safety was not immediately threatened, but if in heavy traffic could have resulted in rear collision. I have submitted a service request to Tesla but will be traveling for the next two weeks so haven't spoken to a service rep directly--therefore no inspection, reproduction, or confirmation by deal or service center yet. No warning lamps, messages, or other symptoms.

I had a major accident on Sep. 24th 2022 when the car sped the traffic light and was hit by another on coming vehicle. This crash has caused a life changing changes to me & others involved in the accident. The vehicle suddenly sped without my control without stopping on the red light. I also had a major financial & vehicle loss with legal activities still pending. Tesla is not investigating and not taking responsibility of this accident and the nearest dealership is avoiding my claims. My auto insurance allstate is handling this claim.

On 9/11/22 at approximately 1:30pm I was driving north on i65 in northern tennessee just before the kentucky border. Conditions were heavy rain. Traffic was moving but heavy. I had autopilot engaged. I was traveling approximately 70 mph. Three lanes of traffic. I was in the far left lane. I had my hands on the steering wheel. Without any prior notice, I lost total control of the car. Seemingly all four wheels were autoplaning due to the wet pavement. I had zero control of the car. The car seemed to slow down, drifted into the full shoulder left lane, then rotated 90 degrees counterclockwise and hit the concrete center median. The car then rotated another 90 degrees counterclockwise and came to a full stop all in the left shoulder lane. The front airbags deployed. There were three people in the car. We were not injured and left the vehicle on our own. Miraculously no other vehicles hit our vehicle.

While driving with autopilot at 65mph, a vehicle 500 yards in front of me was turning left. My car suddenly braked to avoid it.

Phantom breaking - while utilizing cruise control (not even autonomous driving function) the car will randomly slow down/ apply breaks and decrease speed without warning. This has happened multiple times and there is no warning before hand 1) looks to be the cruise/ automatic emergency breaking malfunctioning. Yes available 2) dramatic slow down/ breaking on highways going ~70 mph with cars behind threatens to lead to an accident 3) I have seen numerous corroborating reports but have not taken my car in yet as it does not seem like a solution has been found 4) no 5) no.

The automatic braking came one while I was driving 70 mph on hwy 86 through new york state as we approached 3 of the 5 or 6 overpass bridges. My speed dropped quickly to 50 mph, at which point I hit the accelerator to get back up to highway speed. A similar behavior happened several times on this trip when going though an s-shaped curve. Similar behavior also occurred at slower speed ( 30-40 mph) when a car turn in front of me when the car was about 1 block in front of me and turned safely and cleared my path easily. I would have not braked in this situation.

The car keeps phantom braking at highway speeds when there are changes in the color of the road surface or sometimes when overtaking a slower car or truck in the right lane.

At multiple occasions, there has been phantom braking occurring when on the freeway even when there is no-one ahead of me. Usually does occur when there is a truck next to me.

Whenever I have my car on cruise control on the highway it will randomly brake hard almost causing an accident behind me. I’ve noticed it does it more in express lanes with thin cone dividers / traffic on the other side. I worry it’ll cause someone to slam into me one day.

The car was almost parked and the parking button was about to pressed when the car suddenly accelerated hitting a light pole in front on the passenger side and the car ended up on a lane in a four lane local road perpendicular to traffic flow. The accelerator was definitely not pressed. I have been driving the car for last year and three months and have 26000 miles on it. There was no warning of nearby obstacles or any beeps.

Periodically my car slams on the brakes for no apparent reason. This typically occurs on interstate highways at normal highway speeds. Sometimes there are bridges or other objects observable but sometimes it's on the open road with no cars or visible reason to rapidly slow down. This is very scary especially for my wife that has back pain all the time. We have chosen to not use the automated driving feature fsd because this seems to be where it occurs most frequently. Although we don't drive that much it has happened enough times that we are very concerned that it could cause a rear end collision if we are in heavy traffic.

I saw the article today that other Tesla model 3 and Model Y drivers were reporting phantom braking. My Model Y has been doing this at a specific spot on the 5 fwy south in the carpool lane in santa ana, CA. I now avoid that spot. I thought if it helps to be able to repeat this problem for investigative purposes I can duplicate it at this location.

I installed the full self-driving beta on my Tesla Model Y the morning of 10/24/2021. Immediately after the update installed I began experiencing issues with the autopilot and tacc systems, as well as spurious forward collision warnings. These warnings involved the standard warning beeps and red indicators on the driving display, and at one point included an unnecessary emergency braking incident when no obstacle was in front of me. As such, I had reverted to driving the car in manual mode, not on autopilot, but left the option to use the autopilot systems and associated safety features enabled. I was driving in full manual mode on an interstate in the left lane approaching a tunnel, with no vehicles or obstacles in front of me. The car indicated a forward collision warning with the loud beeps, and the car applied brakes and started to swerve into the lane immediately to my right, in which another vehicle was driving and had to swerve as well. The car detected the event and saved the camera footage to my installed ssd. I have reported the incident to Tesla, including providing the video of the incident. I am awaiting response from Tesla.

The car suddenly picked up the speed in the parking lot, went over the car stopper, curb and hit the tree. The airbags never got activated, or the sensors were nonfunctional. I received a call in less than 1 minute from Tesla roadside if I was safe. Paramedics took me to the er by 911. I had some injuries because of a malfunction of airbags, brakes, and warning systems. The car is towed to the nearby Tesla-approved repair place. I am somewhat concerned about the cause, and I believe Tesla knew what had malfunctioned in their car. I have been a safe driver without traffic tickets and accidents ever in the last 45 years.

I was driving east on may 7, 2021, on I-94 toward new buffalo, mi, on a clear day; no rain. A semi-truck was going 60 mph in the center lane of three lanes. I moved to the left lane to pass as I was going about 70 mph, the posted speed limit. There were no cars ahead of me in my lane for as far as I could see. Another car pulled up behind me very close—way too close—tailgating me. I was passing the truck and was parallel to the truck when suddenly the Tesla automatically slammed on my brakes!!! the idiot who was tailgating me fortunately reacted quickly and also slammed on his brakes and simultaneously swerved hard left onto the shoulder—thereby averting what could have been a fatal accident!! my car could have been pushed into the wheels of the truck on my right and we could have been killed!! I was badly shaken but, fortunately, we were not injured and there was no crash. When we arrived at our destination I phoned the salesman at the chicago Tesla sales office and described the incident. I asked him if I could disable the automatic braking feature and he talked me through the procedure. The Tesla has a rear-facing video camera. I believe Tesla should program that camera to see a tailgating car and make certain that no automatic braking be engaged if a car is following too close!! I believe Tesla should investigate why this happened and should reprogram the software yo prevent it from happening again. I sent the Tesla company two electronic messages through the Tesla phone app as the Tesla salesman suggested, but I have not received any response more than one week later. This is irresponsible!! we could have been killed yet Tesla has ignored my two messages! if Tesla does not fix this problem, it is certain that people will die in a parallel situation. We were just very lucky.

My vehicle fail to stop when another vehicle was in the middle of the road. My 2020 Tesla Model Y did not stop and did not alert me in a upcoming collision incident. My vehicle fail to make a full stop with and without using autopilot.

My 2020 Model Y lunged forward while sitting at a red light behind a pickup truck. I did not touch the accelerator ans the brake would not stop the car. I impacted the pickup truck and damaged the left center of the car front sliding under the pickup bumper. It was as though the car took over on it own. There was no reason for me to have my foot on the accelerator and I was stopped 6 feet back from the pickup in front of me. I am now afraid something is wrong with the car causing this to happen and it should be evaluated by Tesla. I reported this to Tesla and was told I would hear something back in 3-5 weeks. The damage can be fixed to the car but I am now fearful of driving it.

We recently purchase Tesla Model Y on 29th September 2020. We notice more than twice while driving Model Y on freeway at 65mph and the car decided to randomly slam the braked (panthom braking) while in autopilot in middle of the freeway. We were on garden state parkway in NJ. We did reported to Tesla via voice command but no we been scare driving the Tesla on cruise control or auto pilot and worried about rear end accident. Its very dangerous and safer issue. There has been no response from Tesla. While researching about panthom breaking in Tesla, I found so many Tesla car customer having same issues. It's been happening with all the Tesla cars since 2016. Seems like there has been no action taken from Tesla. We notice auto pilot will brake at same spots on the highway near shadow of light in night. This seems to be at exits and it really dangerous. I also read on the net that phantom braking is happens shadows under bridges phantom, I have no reason to suspect it has been fixed. Please take a look into this issue. Its been out there and it is very scary when driving car on auto pilot or cruise control.
