What component or system failed or malfunctioned, and is it available for inspection upon request? experienced phantom braking, especially during dry weather with sun, where there are the mirage of water shimmering across the road. this happen too often when mirage are present. How was your safety or the safety of others put at risk? It get to the point I would rather disable its safety feature and drive manually. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None. Note the driver is deaf, so they are also poor in visible warning compared to audio warning.

RE: Problems with cruise control and random braking I purchased the above model Y performance in June 2022 and we just took our first road trip the last two weeks of August 2022. We started in Sacrament, California and drove to Twin Falls, Idaho, Salt Lake City and return to Sacramento, CA. I started using the auto pilot steering and cruise control on the freeway (HWY 80 eastbound). At freeway speeds the car would suddenly and randomly apply the brakes, sometimes a very hard brake, which was scary and unsafe. I expected this normal feature to work properly on this road trip. As I traveled from Reno, Nevada to Twin Falls, Idaho, this random braking happened over 50 times. I tried several work arounds by disabling the auto steer, the emergency braking and all the automatic options, however, this random braking issue continued. There was no pattern and often it would occur with no other traffic on the road and perfectly clear road conditions. These so called safety features became a safety hazzard. I turned off the cruise control for long stretches because the random braking caused driver stress and fatigue. When I got tired of pressing the accelerator pedal, I would engage the cruise control and my manual work around was to have my foot hover over the accelerator pedal to override the braking manually. This was stressful since I never know when the hard braking would occur. This problem makes the car unsafe and very difficult to drive on a road trip over freeways. It also significantly impairs the value of this very expensive car since a standard feature (cruise control) does not function properly. It is scary to drive with random sudden hard braking. I bought this car for my wife and now she won’t drive it on a freeway due to this serious malfunction. I would like a response as to how you will remedy this problem
The contact owns a 2022 Tesla Model Y. The contact stated while driving 80 MPH on the highway, the vehicle experienced phantom braking. The contact stated no warning light was illuminated. The contact was able to continue driving to his destination. The contact experienced the failure a second time. The contact took the vehicle to the local dealer and was diagnosed with needing to clean the side sensors that was thought to have caused the failure. The dealer cleaned the sensors. The manufacturer had not been informed of the failure. The failure mileage was approximately 13,000.
Car performed sudden and pronounced deceleration while ACC was engaged, for no apparent reason. This occurred intermittently, perhaps a dozen times, over an 800 mile round trip.
Driving 70 MPH on highway with adaptive cruise on. Light traffic, no vehicles on left side. I just passed a semi truck on right side and my car had a phantom braking incident. Slowed from 70 mph to 40 mph in a second or two. No vehicles directly behind me at the time. I pressed on gas pedal and speed resumed to 70. This has happened a couple of other times on a different highway.
Phantom braking was caused numerous times (over 20) during a 2000 mile roadtrip that seemed to be caused by autopilot misinterpreting heat mirages into an object to avoid. This caused the speed of the car to drastically reduce leading to unsafe braking conditions which caused several near rear collisions.
When using the autopilot adapative cruise control feature, the car will regularly think there is a reason to slow down suddenly (the "phantom braking" common complaint). I only use the car on trips, and this happens frequently. While on Route 152, this happened multiple times on a stretch of road that is long and flat. There were no other cars around (and fortunately, none behind me). This probably happened 5-6 times during a 50 mile drive. More recently, it happened on Hwy 99 at least twice in about 30 miles of driving. There were more cars behind me so it felt very unsafe. There was no reason to brake however. It has almost gotten to the point where I do not feel comfortable using cruise control because it will suddenly start braking for no reason. I almost have to have more vigilance when cruise control (autopilot) is on than when it is off because the car might unexpectedly start braking. If Tesla cannot get this fixed, then they should probably stop offering this is as a feature in their cars.
Driving on a highway, after passing a semi I changed to the right lane. I had traffic aware cruise control on. With no one in front of me, the car suddenly braked. I had to step on the accelerator to avoid being rear-ended by the semi. This is 3rd "phantom braking" event in past 2 weeks.
When using the cruise control, the vehicle will suddenly brake losing 20MPH before I can react. It has always happened on the interstates, often with no other vehicles in front of me. On the last 2 day trip the brakes applied themselves at least 6 times. I can no longer use the cruise control as I'm afraid somone behind me will crash into me. Tesla has been no help.
Phantom Braking. The most recent instances of phantom braking occurred on a recent trip to Lake Tahoe. The car phantom braked on the way there on the I-5 on August 5th in the afternoon. I don’t have the exact time, the braking surprised us so much that we didn’t think to enter a “bug report”. The I-5 at that section is a 4 lane divided highway. I think the cause of the phantom braking may have been a bridge that had a slight rise, causing the cameras to think there was oncoming traffic. We had the same issue multiple times on the way home on Tuesday, August 9th. In those instances, we entered bug reports. We also had multiple instances of phantom braking when driving on Route 28 around Lake Tahoe on August 7-9. Route 28 is a 2-lane road with alternating light and shadows from the trees. This may have caused the phantom braking, we entered bug reports in those instances
I have had several incidents with this car. When using either the autopilot feature or just the cruise control. The vehicle randomly brakes very suddenly. It happens frequently when there is nothing in front of us. The two most recent incidents clearly present a huge safety risk. We were driving on the interstate, there was a semi next to us. We were in the left lane going 75 mph. The car suddenly braked for no reason and in a matter of seconds we went from 75 to 55 mph. Had the semi been behind us we would be dead. The other most recent incident was on a four lane highway. There was a truck behind us. We only had cruise control on and again the car suddenly hit the brakes for no reason. The truck behind us had to swerve to get out of the way and avoid hitting us. I have reached out to Tesla and have been told it is a software issue that they are working through. We have had this issue for the entire life of our car so if they are working to update it, they are not doing so quickly.
On a trip from Estes Park to Lubbock on Aug 12, 2022, there are at least two times of phantom braking under Autosteer, and at least three times of phantom braking under Traffic-Aware Cruise Control (TACC). A phantom braking usually refers to a very sudden brake without any clear reasons. In our case, for every phantom braking during Autosteer or TACC, we were on highway with a speed limit or a few percent over speed limit, the weather was sunny and very clear, there was no cars in front of us in our (in any in most cases) lane, and road condition seems to be very normal. There is no warning from the car either. We are willing to have Tesla to examine the data of our car on that day for these sudden brakes. There was a rain on Aug 11, and the car was inside rain (in a parking lot of Fern Lake Trailhead) then and used (under city condition) after rain on Aug 11. Such sudden brake without any warning would be dangerous if there is a car behind this car. We did not have any accident (no car was behind us when such braking occurred). Our car is new, and we just found this problem. It is NOT reproduced or confirmed by a dealer or independent service center. The vehicle is NOT inspected by the manufacturer, police, insurance representatives or others. I did not observe anything abnormal and messages from the car before this phantom braking.
On at least 4 occasions, April 4th 2022 and August 6th 2022 to be precise, I was traveling in my Model Y at highway speeds using Full Self Driving when my car suddenly and without warning decelerated and sharply steered out of the lane causing me to have to forcefully intervene to retain control of the car. On the April 4th date there were no cars or traffic around, the incident just happened, on the August 6th incident I was on 495 in fairly heavy traffic and was afraid that I would cause an accident because of the sudden and violent nature of the braking and turning of the car. The other incidents were also at traffic speeds in light traffic.
Tesla cameras are equipped with internal cameras intended to monitor driver attentiveness while using “Autopilot” features. The internal monitoring can be bypassed by simply covering the camera. This reduces the attentiveness checks and can be a danger as drivers will use autopilot functionality without proper attention on the road.
Multiple times while driving across I-70 through Kansas, my car suddenly broke and slowed down at least 10 mph for no reason. There was nothing in the road. One time it even identified a mile marker as a motorcycle. I was almost rearended when it hard broke three times in a row and threw myself and my children forward forcefully. I realize this is an issue under investigation, but until people like myself continue to complain and wonderful folks like you force Tesla to make changes, it is going to continue to be an issue. It's not safe. Thankfully I WAS in the middle of Kansas every time and there was no one around (except for the above mentioned incident where the van behind me was gracious enough to pass and could clearly tell I was having difficulty with the car). If this happened in a crowded area, I for sure would be in a high speed collision. After it happened on my outbound trip, I tried to make note of it on my trip home: what was around me, what the camera was "seeing" on the screen, etc. I noted already the motorcycle instead of a sign. It also seemed to have real difficulty when I could see a mirage and reflections (as it was over 100 degrees out) but I genuinely don't know if cameras can see mirages or if that is only human eyes. Thanks for your help in pursuing the issue!
I took delivery of a Tesla Y in February 2022. About a half dozen times since, I've been driving on the highway using cruise control/auto pilot and the car will randomly slam on it's brakes, so hard that loose objects in the car are flying to the front. There was no warning prior or any of these incidents. Thankfully I have not had cars directly behind me when this occurred...if there had been someone behind me they would have absolutely hit me. I have not yet contacted Tesla.
We are on a cross country trip on open highway and it randomly applies the breaks hard at times for no apparent reason.
The "advanced autopilot" feature is extremely dangerous in certain conditions especially construction zones, if a bug is on the windshield, while it is raining or night time without street lamps. I purchased this car as a full time rideshare driver for nearly $100,000 after driving the car for less than 1 month the car has terrified myself, my passengers and my pregnant wife and luckily hasn't killed any innocent bystanders, yet. While in autopilot the car will frequently 'phantom brake' when there is literally no vehicles in front of it, quickly reducing speed from 70mph down to 40mph. This most recent time 7/28/2022 I had a garbage truck like vehicle behind me but thank God I have excellent reaction time and canceled the autopilot and smashed the accelerator just in time before causing a pileup on the expressway. The car constantly misreads speed limit and street signs and will confuse the SR46 little sign for a speed limit sign and slam on the brakes from 65mph down to 46mph. Just yesterday the car decided to go in the middle of the two lane highway and slam on the brakes in the middle of the highway, twice, which terrified my wife and I caught on my 3rd party dash cam. I have tried to reach out to 3 Tesla emails and even SpaceX but I receive no response, big surprise. Additionally I'm smarter than the average bear and use a 3rd party GPS miles tracking app on my iPhone called Everlance which when I've cross referenced with my Tesla app about driving range its not even remotely close to their 303 mile range. I am proving a 33% discrepancy between their claim of mileage and what the car is actually achieving on the road. For example I charge at home to the recommended 90% charge of 269 miles, drive 99.1 miles over about 4 hours and get back home with 80 miles range. 269 - 99.1=169.9 miles but with only 80 miles on the battery that's actually less than half what it should be. I paid $6,000 for FSD I never received and have requested a refund without a response.
While using cruise control (Traffic-Aware Cruise Control) on a recent road trip in our Tesla Model Y, the car unexpectedly and for no apparent reason, abruptly reduced speed. Our car is available for inspection upon request. Our safety and that of others was put at risk as a result of this unexpected reduction in speed while travelling on the highway. An accident could have occurred if cars travelling behind us did not similarly reduce speed to avoid a collision. The problem has occurred on a number of occasions where there was no apparent reason for the car to rapidly reduce speed. It has not been confirmed by a service center. The vehicle has not been inspected by the manufacturer or others. It is a known problem with the 2022 Model Ys based on a published inquiry by the federal safety agency (ref: https://electrek.co/2022/06/03/tesla-respond-increase-phantom-braking-complaints/). There were no warning lamps or indicators prior to the unexpected braking event.
We have owned the car approximately 2 weeks and have had 3 episodes of inappropriate activation of emergency braking. The first two were minor slowing of the vehicle when traveling on interstate highway when the system was activated by dips in the road. The third involved a parked pickup truck on the shoulder of the outside curve of a road - resulting in aggressive braking of our vehicle. Frightening. Thankfully there was no closely trailing vehicle. We have inactivated the system, notified Tesla, and scheduled a service appointment.
As I was pulling into my driveway with the autopilot completely OFF the car started to accelerate hard on its own which could have resulted in an accident had I not been ready for it. Also unrelated to the previous statement; Driving along at 37 mph with the autopilot on, the car slammed on the brakes for no apparent reason nearly resulting in a rear end collision to my car.
Phantom braking occurs very frequently and the dealerships tell me there’s nothing that they can do. We almost got rear ended on a 65 mph highway because of one instance but it happens on a daily basis if using cruise control.
The contact owns a 2022 Tesla Model Y. The contact stated while her husband was driving 65 MPH with cruise control activated, the vehicle inadvertently stopped without driver input. The contact stated no warning light was illuminated. The driver was able to continue driving 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 3,550.
In accelerating of itself, both my own life and that of a potential bystander were in danger. I had no time to react to the sudden acceleration. This has never happened to me in over fifty years of driving and it was very obviously the result of a car malfunction. In addition, the automatic emergency braking function failed. There were no previous messages, symptoms, or signs. The car has been at the shop for three months. The dealer has failed to give us any feedback as to why the accident happened. All they have said is that they don't have the parts that they need to change. It was only after two and half months that they reached out to me. During one of my visits, one of the dealer's service representatives took me aside to inform me that she could not divulge any information about the causes of the accident, and that my case was a “legal one”. I still don't know what any of this means. In addition to all this, the pen drive located inside the glove compartment of the vehicle only has two days of picture and video information, and the file of the day of the accident is empty, which is extremely suspicious. I suffered burns from the airbag, and my cervical region was affected.
On my first long road trip using Tesla's Traffic Aware Cruise Control (TACC), I experienced Phantom Breaking (PB) issues. Some of these PB's were mild some with very aggressive responses. I was using just the TACC part of Auto Pilot, sometimes with vehicles near me, sometimes not. After 5 or so of these events in 300 miles or so, with one event early on my return trip, I stopped using all of Auto Pilot. The vehicle is new with no other issues. Software package 2022.20.6
While driving at highway speed and in adaptive cruise control, my car experienced abrupt deceleration. This happened at least 6 times in the course of a round trip from Austin to El Paso and back. In each instance, there was no nearby obstacle, such as a vehicle or debris or an animal. All driving was done in daylight, and the car wasn’t traveling through an underpass or any other shadow.
I received my 2022 Tesla Model Y a few weeks ago and quickly began to notice intermittent sudden breaking when utilizing the "Auto-pilot" feature. Because of these incidents I rarely utilize this feature any more. Today during an out of town trip, on two occasions when utilizing cruise control the car suddenly applied its breaks. During both occasions there were no other vehicles within 100 yards and the freeway (I-17 in Arizona) opposite direction lanes were separated by hills/rocks and not in direct eyesight.
Phantom braking — the car brakes for no reason in navigate on autopilot as well as adaptive cruise control. The phantom braking is particularly extreme on I80 through Nevada and US Rte 95 through Oregon, which is a two-lane road.
While driving on highways /interstates and using the vehicle cruise control or autopilot, the vehicle will suddenly apply the braking system when there is nothing in front of it. I would list specifics, but it happens every time that we take the vehicle on the highway/interstate, usually within the first 15 minutes. This has happened multiple times on trips, at 80mph (South Dakota) or at 65mph. I have noticed that white vehicles tend to trigger it more than others, even if they are just sitting on the side of the road or parked in a driveway off of the highway. Hills also seem to throw it off, when you are at the top and just over the crest, it has applied the brakes multiple times. This has gotten progressively worse since I've owned the vehicle (Dec 2021) which is why I am only now reporting it. I will no longer use it as I firmly believe me or my family would be seriously injured or killed if there is a vehicle behind me, especially at 80 mph that was not expecting the car to brake hard and as a result rear ended me. This is a significant vehicle vision system issue and it really does need to be addressed before lives are lost, if they have not been already. There are no other issues with the vehicle, no warning lights on and absolutely no indication the vehicle will apply the brakes until you are suddenly lurched forward due to rapid deceleration. I understand this is already on the federal safety agency radar but believe this is a much larger issue than is being reported.
The car system been keep crash cause it screen frozen and while crash it will no speed display no ac no warning no back up camera and important after lifting gas pedal the car will not reduce speed as before and I almost crash the car. Been report the problem to Tesla since early July and the keep cancel my appointment said it need wait for updates but can’t provide the date. I requested get the loaner while they can’t solve the problem but they denied and cancel my service appointment . It dangerous to drive and very unpredictable when the system crash while driving. While driving expect the car will reduce Speed but it not and no speed will display will cause over speed limit. The the pre collision system will not work at all and the system crash every few minutes and screen will shut off it self. While system crash will need triple amount of force the press on brake pedal to stop the car when it on high speed it impossible to respond to stop at short distance.
