Nearly Every Single day on my drive home north on AZ hwy 90 my 2020 Tesla Model Y abruptly disengages and breaks from cruise control. it is especially startling when I pass a vehicle and then return to my lane only to have the car dramatically slow. I could be ok if it just disengaged cruise but daily multiple times it breaks on a fast moving highway

⢠Cruise control braked hard unexpectedly and for no reason. I'm describing a specific instance here, but this happens regularly. Specifically, the traffic aware system frequently misinterprets the data it is collecting. In this case, a car in an exit lane, slowing down to take a ramp. I was not in that lane, but there was no painted line between my lane and the exit lane. My car slowed to match the speed of the car on the exit ramp. In other cases, my car has slowed drastically when a car in a slower lane slightly veered into my lane by only a couple inches. There has been no risk of a collision when this happens, but my car suddenly braking then causes a new risk of collision for the cars behind me. ⢠Car rapidly decelerated from 70mph to 35 mph while there was another car behind me. He was caught off guard and had to manually brake hard himself to avoid hitting me â¢Â There are numerous independent confirmations of this behavior online, but I do not specifically know of any from an official "independent service center." Tesla denies the existence of the behavior. ⢠There is no real "component" to inspect, this is a software issue â¢Â There were no warnings or other indications before it happened.
While driving on the highway at 59 mph using Tesla Autopilot functionality the vehicle braked so hard the wheels locked up and skidded without warning. There was no vehicle directly in front but there were two semi trucks on either side and vehicle directly behind me. The vehicle behind had to brake hard not to run into me. I took control of the vehicle and pressed the accelerator to regain speed and avoid an collision.
Phantom braking during a drive on highway. Out of no where, the car breaks even when there is no one stopping in front of you. This resulted in car behind panicking and almost rear ending.
While driving on highway using cruise control, the vehicle (without the driver's assistance) applied brakes to quickly slow the rate of speed. This occurred three times in the span of ten minutes. The weather was sunny and no other vehicles or objects were in the vicinity of my vehicle. After the third occurrence, I stopped using cruise control for the remainder of the trip.
On a 900 mile drive, in one day, the “speed cruise control” would abruptly brake, as if it were seeing someone in front of us. It did this at a minimum 5 times. Never was there a car closer than 1/4 of a mile in front of us. Once it went from 78mph to 38mph in about 3 seconds, when there was a car about 3 car lengths behind us. On the return 900 mile drive it continued, at a lesser rate. I have reported this to Tesla, and they claim “my” car reports do not show anything out of the ordinary, and these errors are sometimes caused by…and they gave numerous reasons, such as speed limit data inaccuracies, etc. they also have determined that my car does not show any computer faults so there is nothing they can do. Unacceptable
During routine highway driving while using the included Autopilot (Adaptive Cruise Control) software, the vehicle will suddenly and without warning abruptly slow and apply breaks. This slowing can occur when traveling at 70mph (the posted speed limit) and attempt to slow to a speed of 45mph. This change causes a great safety hazard in the event of being closely followed or rear ended. This phenomenon is known to tesla and been colloquially termed "phantom breaking". No hazard or other external reason is present to merit a sudden breaking.
While on cruise control at @72mph the car has been “phantom” braking. The last time there were flurries, but the first several times there was nothing impeding the car nor were any vehicles within camera range. This is a very unsettling feeling. No, no and no. There have been reports to your site with this regard. tyvm
The GPS is malfunctioning- showing the car in a random location, direction and speed. All automation needs to be disabled. The car will attempt to make a non-existent turn based on where it thinks it is, or will speed up or will suddenly decelerate because it thinks it is coming up to a cross street or traffic control.
Re: VIN-[XXX] My wife was driving the car in this accident. I am reporting it as it happened. When: Oct 29, 2021 at about 2:45 +/- 40 minutes. Where: in the parking lot of a shopping center. In Quail Hills shopping center in Irvine, California. Summary of what happened: a) Unintended and sudden acceleration. The car accelerated suddenly by itself and caused an accident when I was trying to park the car. b) Two more cars were involved and were damaged. My car did not respond to brake and it hit two other cars. c) The car was inspected by repair center and was fixed. Damages were extensive. d) A warning appeared on the screen that said "Automatic braking disabled." during or after the accident. e) We reported the accident to Tesla and requested the EDR/crash data report. They have not provided that. I called several times, sent emails and even went to a Tesla service center. But have no received the report yet. The best way to reach me is via my cell phone:[XXX].

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
Touchscreen repeatedly freezes. Won’t show gear selection, speed, or any other items. The touchscreen freezes then takes some time to crash to black screen before reboot. Has happened daily since Tesla update. Tesla refuses to provide a fix and continues to tell us to wait for an update. This is unsafe.
Four times in the last six weeks (three while driving) the car has lost all power. My screen either freezes or goes completely black so I have no speedometer, the blinkers do not work, I cannot control the windows or open the doors without the manual override. This usually lasts for 3-5 minutes, sometimes longer - and then the computer resets and everything reloads. Tesla is telling me it is a known issue and I have to wait until they figure out the firmware issue and get the next update. They were not at all concerned about the safety of the car and gave me no suggestions on how to continue to drive safely. The date entered below is the most recent occurrence
While using adaptive cruise control, the car decelerates for no apparent reason. The rapid deceleration of the vehicle could cause the following car to rear end my car. There is no warning when this occurs. I have not reported it to the manufacturer because forums and news show that all owners are impacted. This has happened many times.
Operating the vehicle at highway speed of 70 miles per hour on interstate 80 in Illinois. No visible traffic going in either direction for approximately 1/2 mile in all directions when the automatic braking happened for no apparent reason. Scared my wife and myself (both 74 years old) to death. Threw us both forward. My wife now refuses to drive in this Tesla and wants me to sell it. "Phantom Braking" is not an acceptable phenomenon. If there was a tailgating semi behind us we would both be dead today before people die. This must be fixed!!!
When using the autonomous driving mode, the car unexpectedly decelerates with no warning and with no obvious traffic or other issue triggering the behavior. This has happened several times in dry, light conditions with no surrounding traffic. After experiencing this I have not used the autonomous mode again as it's completely unsafe.
We were trying to park the car at Costco Parking lot on Jan 14th, 2022 in the early afternoon. A car had pulled out of a parking spot and indicated us to move forward in that spot. When we tried to move forward,the vehicle suddenly accelerated and hit three other cars. The airbags did not come on. We have asked Tesla to look into this and are awaiting a response. There was damage to front end, both bumpers, hoods, front grill etc. The accident was reported to the Police, Insurance Company and Tesla. The vehicle was towed to Tesla dealership and then was sent to another repair facility, Gerber Collision in Beria, Ohio.
On open freeway, I 76 between 7 am and 8 am Tuesday November 16, between Ogdallala NE and Brush CO. Using adaptive cruise control with autopilot steering (as well as without autosteer), multiple episodes of severe "phantom breaking" where the car slams on the breaks for no apparent reason. No other cars around. Flat, clear open freeway. Reported the issue to Tesla service. Even though there were multiple (>10 episodes in one hour) they have demanded to know the exact time stamp. I was able to give time within 1 hour period, vehicle location. Service says if there is a hardware issue they will look at it. If it is "firmware" it will need to wait for a firm ware update. This is dangerous. What if the car slams on the breaks at 80mph, with someone following close behind? You might be rearended. Really serious safety issue. My car has latest FSD beta 10.4. This is much worse than before this "upgrade"
The car accelerates on its own, twice in last two weeks. First time was at a intersection, I applied accelerator pedal after the light turned green, with normal pressure. The car sped up unexpectedly and I had to immediately apply brake to slow it down. The second time I put it in reversal and as soon as I applied accelerator it jerked and sped up unexpectedly. Luckily both time the acceleration occurred when car were in slow speed and applying brake stopped acceleration. it also occurred twice before these recent two incidents since we bought the car 10 month ago but they happened far apart in time and we were not sure of its occurance. But the frequency with which the unexpected acceleration happens has become alarming and we become more sure of the certainty. I start to worry about what would happen if this occurs when the car is moving at high speed and whether applying brakes can be effective to correct the acceleration.
My wife and I drove into a parking lot in a strip mall located at 1301 IL Route 59 to park the car. I was driving very slow at 5 miles an hour. As I pulled into a parking spot facing IL Route 59 which is a three lane highway, the vehicle malfunctioned causing it to uncontrollably accelerate. I was not able to control the car as it jumped the curb of the parking lot and went through the grass on the side of the roadway towards IL Route 59. To avoid driving onto IL Route 59 I was able to steer the car right and struck an AT&T telephone box which brought the car to a halt. Police arrived on the scene to check the status of the accident. A police complaint has been filed. Police did not issue a citation to me as this was not my fault and there was clearly a defect in the car that caused this accident. Luckily my wife and I were not injured and the car was towed to a body shop for repair. I called Tesla customer support and they said that they would review the car diagnostics to determine the problem. There were no warnings, symptoms or messages to indicate this behavior by the car. It just accelerated in its own. Please see attached documents for more information.
On three occasions after taking my foot off the accelerator, my car starting accelerating on its own. I could feel the acceleration and was able to stop it by putting my foot on the brake. I did not touch the lever to set the speed, the pedal did not get stuck on the carpet and I did not confuse my accelerator for the brake. This seems to be a very dangerous situation, especially in heavy traffic or if I did not immediately react to put my foot on the brake. Each time this happened while the car was in motion and after I had taken my foot off the accelerator to allow the car to slow down. Instead it sped up. Since this happened on three occasions, the dates and mileage at the time are not exactly as indicated below.
I was in a parking garage next to my work and was parking between two cars, I was coming to a complete stop when my car suddenly accelerated and hit the pillar on the left side. It was only a few seconds and I applied the brakes and put the car on park. This is a brand new car with less than 500 miles on it. I felt that the car suddenly accelerated when I was completely stopping. Later, I found out that this has been reported with other tesla vehicles in a parking garage similar to my situation. Tesla still has not provided the report to me saying it is proprietary information, but take no responsibility. Damages has cost me almost $10,000. I have been driving for more than 30 years and I have a perfect driving record.
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.
Went to see an eye dr, try to get to a parking spot which there were a whole row of empty parking spaces. As I turned into the parking spot it suddenly accelerated over the curb, I then applied the brake but still keep going then it the wall about 8ft fr the curb straight on. I've been driving for 35 yrs and never accidentally apply to wrong pedal. I went to tesla near by to complain right away and they insist I have applied to wrong pedal! Such a irresponsible statement! I dont have to drive the car again if you can send someone to investigate if the car has some recording to view like a blackbox for an airplane.tesla may claims they r right for other cases they have but I m very sure I never accelerate into the parking spot. I have the video recording the car driving and you can see it started accelerate as I turned into the parking spot like many people claim on the internet that they experience similar situation.
Tl* the contact owns a 2020 tesla model y. The contact stated that while his wife was driving into the driveway of their resident, the vehicle accelerated forward without warning and crashed into the garage. No air bags deployed. The contact mentioned the safety collision did not function. The contact sustained injuries from the seatbelt to the neck, chest, shoulders and upper back where he was taken to urgent care then taken to the hospital. The wife who was the driver sustained minor injuries to the chest, arms, and neck where she received medical attention for at an urgent care. No police report was filed. The vehicle was severely damaged on the front drivers side. In addition, the garage door frame damaged. No dealer was contacted. The vehicle was not towed. The manufacturer was notified of the failure and informed the contact that an engineer had to estimate the vehicle damages. The failure mileage was approximately 800.
This is my third tesla (model s and x and now y) in the last 10 years. I was the primary driver having over 40k miles driven. I do not suffer from any medical problems. On monday morning october 5th around 9am I made my way to my local supermarket. I pulled into the parking lot slowly. The tesla model y was less than a week old, so I was driving extremely slow trying to find a parking space where I would least likely get a doording. I spotted a space, and proceeded to slowly turn into the space. As I was pulling into the parking space, I slowly took my foot off the accelerator (gas) and noticed that the car was not stopping, usually as soon as I took my foot off the 'gas' the car normally stops abruptly. The car was not stopping. I noticed a woman and child in my path, so I put my foot on the brake, the car did not stop. The car jumped a curb and proceeded to pin the woman in my path against a wall and the tesla y model. I drive with one foot only, and I have never confused the 'gas' for the brake. There is something wrong with this car. There was $16k damage to the front of the car but no airbag inflation.the damage to the pedestrian is currently unknown.
I was slowly pulling the tesla model y, VIN #[xxx], on tuesday morning, september 1, at approximately 11:15am. I was about 3 feet from the front of the garage when the car without my prompting suddenly rapidly accelerated into the cabinets and ruined them along with the wall they were hung on, removing the wall from the foundation. This also caused considerable damage to the car which only had approximately 450 miles driven on it. We also own a tesla model 3 which I have driven extensively therefore making me very familiar with the tesla drive train. In no way was this any type of operator error as tesla has suggested after their review of the vehicle data. This is clearly a design flaw with this car and thankfully there were no serious injuries associated with the crash. I am extremely shaken up by the incident and won't ever feel confident driving that car again. Photos of the damage are available for review.
