When driving with adaptive cruise control turned on, the vehicle suddenly slowed down for no apparent reason. No other vehicles were nearby, no nearby structures, no paper or debris drifting on the road. This happened about 6 to 8 times over two days. I am glad that no one was following me.
2022 Tesla Model Y driver assistance complaints
Page 15 of 19: complaints 401 to 430 of 531, newest first, as owners wrote them.
Tesla Y has a special setting for carwashes, that driver has to enable, which puts the car in neutral, closses all the windows and plus some more. Unfortunately system failed; car accelerated on its own and I hit a car in front of me, so it failed the second time and car didn't stop on its own to avoid collision. I called Tesla and this incident is under their investigation.
While cruise control is engaged, the vehicle will slam on the brakes when there are no obstacles or vehicles nearby. It happens out of nowhere and without any warning from the vehicle. We live in a more rural area and has happened on the interstate there each time. It is not a highly congested road and each time it has happened, there is nothing around. It has happened on numerous occasions and will take the car from 80 mph and attempt to stop completely. This could easily cause a rear end collision at high speeds if there had been a vehicle in close proximity. This has also happened even with the Automated Emergency Braking disabled.
I was driving down the highway and as another car in front of me exited the highway my car suddenly and abruptly slowed down even though my lane was clear endangering me and the people behind me. This is at least the fourth time this has happened to me. I find the adaptive cruise control / autopilot to be defective and extremely un safe
I was driving with the automatic emergency breaking system on and the car slammed on the breaks when traveling at around 35 MPH even though no car or other object was in my path of travel. It just slammed on the breaks for no reason.
Random, sudden braking while in cruise control (auto pilot mode). There is NO object or other vehicle in the way when this happens. It has happened many times starting in December 2021 in a brand new vehicle and happened most recently 3 days ago. Every time it happens it is scary. Very disturbing and renders cruise control unusable. No word from Tesla that this is fixable or even a priority. Please make Telsa address this serious safety hazard before someone is hurt or killed. Thank you.
The contact owns a 2022 Tesla Model Y. The contact stated while driving 70 MPH with the Self Driving feature activated, the vehicle experienced phantom braking. The dealer was made aware of the failure and informed the contact that the vehicle was in learning mode and needed a software update. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 50.
While driving at highway speeds the vehicle will brake suddenly. This has happened more than eight times in a single 100 mile trip. Potential for crash at high speeds and very unnerving for the driver and passengers.
I just bought a brand new Tesla Y and the next day went on a road trip with my wife and two little kids in the back seat. I put on AutoPilot. While driving it suddenly decelerated, which nearly caused an accident. A tractor trailer almost slammed in the back of our car. This created great anxiety and fear. The next day, with me driving alone, I tried it again and this "phantom braking" occurred. This is very dangerous. PLEASE pressure Tesla to look into this. Why do we need a tragedy for the federal safety agency to investigate?? This needs to occur now.
I have owned my car for only 2 weeks. Every single night that I am driving home from work (50 miles away), I have significant phantom braking. Most of the time I lose around 5-10mph, which is startling and could cause an accident if someone behind me wasn't paying attention, but once last week, while going 70mph I dropped almost 20mph within a second. Luckily, there were not any cars directly behind me. If there had been, I would have been rear ended. It is extremely frightening and only happens when I am using the cruise control. Every time it has happened, there is nothing in front of me. It's on a stretch of interstate that is 2 to 3 lanes wide, on both sides, with a large grassy median. No possible on coming traffic. I have not received any warnings or messages before, during or after.
I would like to add a complaint for the phantom breaking while using the Autopilot function of the vehicle. While on a road trip across the country, I've experienced sudden deceleration while Autopilot was engaged. Nothing was impeding the vehicle and the screen did not note any obstacles. The weather was clear and it happened both during the day and at night. This feels extremely dangerous, as my control over the vehicle could be lost under different road conditions.
Phantom braking occurs under too many scenarios common on 2-lane roads to mention them all. Sometimes the car decelerates so rapidly for no apparent reason I'm concerned I'll be rear-ended. Even in good weather, lighting, road surface, etc. The car sometimes seems to be guessing about hazards and slowing down for no reason, sometimes very abruptly.
When I have Autopilot (adaptive cruise) on, the car will often slow down, sometimes quite abruptly, when there is nothing to slow down for. This is often called Phantom Braking. This can easily put me at risk of getting rear-ended from another car. If I'm on ice or snow it can cause the car to slide and loose control. I have read on the internet and forums of many with 2021 or 2022 Model Y's with the same problem - since the radar was removed on these newer cars. I had a 2020 Model Y previously that had the radar, and I never had this problem. I believe their camera only technology is not enough to suffice and they need the redundancy of both radar and cameras.
I was driving 55Mph with Autopilot engaged. Without warning the car engaged the brakes aggressively and I was almost rear ended.
Sudden braking when TACC is engaged happens sporadically
I had cruise control set(Autopilot) and was driving on a two lane highway at night. My car abruptly braked when oncoming traffic was detected. Another oncoming car on the same road, caused my car to abruptly brake again. Then a third car a couple of minutes later caused my car to abruptly brake again. I turned the cruise control(Autopilot) off, to prevent my car from emergency braking. The problem was not reported since I couldn't repeat the issue. It has not been inspected by anyone. No warnings on vehicle.
Phantom braking happens during auto pilot feature and during any use of cruise control. This happens nearly 100% of the time while using these two features and any incoming traffic approaches, especially larger vehicles and trucks. The braking is sometimes soft, but more often quite abrupt, and always without notice. It is extremely dangerous and annoying to use
While driving from San Francisco to Salt lake city and back on highway 80 this past week, my vehicle frequently experienced “phantom braking” while using “autopilot”. At least 15 times on the drive, my car, while using “autopilot”, would forcefully apply the brakes when no hazard was present. While most times it slowed the car from 80mph to 70-75 and then resumed normal operation, one time it slammed on the brakes so hard and dropped the vehicle speed down to 50 before I could intervene and avoid a rear end collision. The system was even worse at night, but only when passing large semi-trucks. They were in the right lane and as my car would approach to pass in the left lane it would slam on the brakes and slow down. It got to the point where I would turn off autopilot every time I was about to pass a truck at night. I also noticed it only seemed to happen on two lane highways—two lanes in each direction, and only when I was in the left lane, again mostly as I was passing a large truck that was driving in the right lane. This is particularly concerning as a few times there were cars behind me that could have easily rear ended me as there was no hazard indicating that they should slow down.
I experienced two incidents of phantom braking while making a round trip from Reno Nevada to Sacramento California on Interstate 80 on March 3, 2022. The first incident (approx. 10:15 AM) occurred west bound and west of Donner summit. My speed was approximately 70 MPH traveling in the right lane. Several big rig trucks were parked on the shoulder. There were no cars directly in front of me and one car slightly ahead in the left lane. Autopilot was engaged. Suddenly the car braked violently and reduced speed to under 40 MPH. I retained control and continued driving. In the second incident (Approx. 1:30 PM) my wife was driving east on I 80 (with autopilot engaged) at approximately 70 MPH. As she attempted to change lanes to allow a car to pass to our left, emergency braking again was violently engaged. The car behind us had to take very quick evasive action to avoid a collision. A high speed collision was extremely narrowly avoided. There were no vehicles for hundreds of yards ahead of us nor any parked along the highway and no obstacles on the highway. At the spot where the braking occurred the highway began to slope upward, possibly creating the illusion of an obstacle..
We recently purchased this vehicle and was driving down the highway with zero traffic near us in any lane and the Model Y slammed on the brakes for no apparent reason. Luckily no one was behind us. This continues to be a problem with phantom braking for no reason. It’s very dangerous and almost makes the vehicle unable to be driven.
When in Traffic Aware Cruise Control the car would brake suddenly for no apparent reason. I’m not sure whether it is available for inspection upon request. Sudden unexplained braking could be a safety hazard if it occurs when a vehicle is travelling behind. The problem has not been reproduced or confirmed by a dealer or independent service station. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. This problem occurred at least 6 times when travelling on the highway between Lake Charles, LA and San Antonio, TX on 2/27/2022 and 24 times when travelling on the highway between San Antonio, TX and Las Cruces, NM on 2/28/2022. We observed that the frequency of these sudden unexplained braking occurrences increases when the light is filtered through partly sunny/partly cloudy skies. In bright cloudless conditions or in overcast conditions the unexplained braking does not happen. On 3/1/2022 the day after we had 24 occurrences we drove from Las Cruces, NM to Scottsdale, AZ in bright cloudless conditions and we didn’t experience any sudden braking.
Phantom Braking occurred four times in under an hour. Sunny conditions, clear lines.
When the ADS is engaged you can not reliably drive the vehicle due to phantom braking events which puts us at risk of being rear ended at highway speeds. Has occurred on numerous dates.
Using autopilot (adaptive cruise control) on a two lane highway. Vehicle slammed on brakes when a semi truck was passing on the other lane. Happened three times on same trip. False braking was not consistent as it happened once as semi passed beside us, once when the other vehicle was at least 100 yards away and once again when another truck was about 25 yards away. Lane in front of us was clear with no traffic in front of us. This did not happen on divided highways. Only on two lane highways at speeds above 55mph. In one occasion braking was so severe that vehicle slowed down from 55mph to about 20mph. A car behind us almost rear ended us. They honked their horn at us as they believed we were "break checking". Not the case. My wife asked to turn feature off and won't use until something is done to fix. The car has not been checked by Tesla. I have an appointment with them. There are no diagnostics indicating fault in the car.
The contact owns a 2022 Tesla Model Y. The contact stated that while driving at an undisclosed speed with the cruise control or autopilot activated, the vehicle experienced phantom braking. The dealer was made aware of the failure; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure and informed the contact to press a button on the steering wheel to submit a bug report. The failure mileage was approximately 100.
Sudden braking events that occurred both during the day and at night - reducing the vehicle from a cruising speed to 55 or less mph within seconds.
On the freeway, the car significantly slows when it perceives a hazard, despite no hazard. It’s the phantom breaking and it reduces the speed suddenly and alarmingly, and it renders the cost and benefit of the vehicle much less valuable.
on 2/25/22 I was driving on a two lane road. Speed limit was 55. I set driving assistance/adaptive cruise (we do not have the option for fully automated driving) and things were fine for 20 minutes. At some point there was a significant slow down despite the fact that there were no cars in my lane ahead of me. I'm not sure if the car detected another car coming from far away in the other lane or why it was that the car significantly slowed down.
* on rural roads at night, utilizing either cruise control or autopilot is super dangerous. ANY oncoming traffic will cause the vehicle to audible warn, and slam on the brakes. * I was almost rear-ended multiple times by vehicles following closely when the car decided to slam on the brakes. * I can reproduce it, and I have recorded it. * no * no symptoms prior to failure. Occurred on brand new car, started on the very first night driving it in rural environment.
Phantom breaking happening while using auto pilot (cruise control). It is not speed, weather, terrain, or time of day dependant, and seems to be increasing. It is extremely dangerous in highway driving when speed is 55+. Phantom breaking can be anything from light breaking, to heavy jerking breaking. It has happened on multiple dates dince purchasing car at start of month (2/2022). We have put a service request into Tesla.
