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.

On drives longer than 40 miles, camera faults cause cruise control systems to degrade in function and then when the faults are cleared, full functionality resumes without driver alerts. Side repeater camera feeds and rear camera feeds inconsistently load, or take an extended time period to load (10+ seconds). Tesla has confirmed that the autopilot computer (HW3) likely needs to be replaced, but this error/messaging is not directly accessible to the customer. The inconsistent failure behavior of the vehicle could easily lead less technical owners/drivers to incorrectly interpret how the car is behaving. The only message you receive while driving could be that 'cruise control is not available', and 'automatic emergency braking unavailable' with a message that the features may be restored later in the drive. My coworker has a 2022 Model Y and the same component failed on his vehicle and needed to be replaced under an extended warranty that was purchased from Tesla. I'm unsure how widespread the failure of this critical safety system is; we both purchased FSD and both had the same component fail and need replaced. I don't personally know others who own this vehicle with the FSD package to know for sure.
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.
The contact owned a 2020 Tesla Model Y. The contact stated that while reversing at low speed from his driveway, the accelerator pedal inadvertently depressed into the floorboard, resulting in sudden unintended acceleration. The contact depressed the brake pedal, but the vehicle failed to stop immediately. The vehicle struck two other parked vehicles in another driveway before crashing into a residence. The residents were not injured. The contact sustained a fractured neck, and shoulder pain from his seat belt, and head pain from striking the steering wheel. The contact's front passenger sustained a bruised shoulder, and the rear passenger, who was laying down on the rear seats, rolled over during impact and hit the rear seats, sustaining back and leg pain. The contact and his passengers were transported by ambulance to the hospital. A police report was filed. The vehicle was towed to a tow yard, where it was deemed totaled by the insurance company. The manufacturer was made aware of the failure and informed the contact that after reviewing the event data recorder (EDR), the data showed that the contact had his foot depressed on the accelerator pedal during the failure. The failure mileage was approximately 14,000.
The contact owns a 2020 Tesla Model Y. The contact was driving approximately 3 MPH as she was parking the vehicle, front end first, the vehicle independently accelerated as she removed her foot from the accelerator. The contact stated no warning light was illuminated. The contact's vehicle crashed into the vehicle's front end that had already been parked, the vehicle was not occupied. The contact stated that she depressed the brake with force. The contact stated that the force of the crash had moved the other vehicle out of the parking spot and into the lot. The contact's vehicle had a crushed front bumper and the other vehicle also had damage to the front bumper. The contact's vehicle was drivable. There were no injuries and the police were not involved. The contact had not been taken to a local dealer or independent mechanic. The vehicle had not been diagnosed and had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 23,000.
While driving at highway speeds (50mph-80mph), on 2 lane or 4 lane highways, in the day or night, in sunny conditions and overcast sky's, while using the cruise control (auto-pilot), the car will suddenly and unexpectedly apply the brakes. It happens between 8 and 10 times on every road trip, each way. Not only is it a shock to me as there is never a visual obstacle that seems to be causing the hard braking, but it is a dangerous safety issue to other motorists too. This has caused cars behind me to take evasive maneuvers to avoid a collision. Other motorists have mistaken this hard braking as me "Brake-Checking" them and very nearly cause a road-rage incident. I've had the car for about a year and have opened several service appointments with Tesla. Each time they close the case before the service appointment with a version of the reply "this is normal" and "there is nothing to repair". They also claim that the car will learn how the react next time by my reaction to the incident this time. I have reacted the same way (by pushing the accelerator pedal until it regains forward motion) each time this has happened in the 8-10 times on each of the 6-8 road trips I've made in the last year. Clearly, the car isn't learning anything from my reaction to the sudden and unexpected braking. My safety is worth my time to make them take this seriously as they don't seem to be concerned with my safety!
Car accelerated on its own, with no pedal pressure. My right foot was on the mat
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
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
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
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!!!
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.
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"
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].

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.
