2020 Tesla Model Y Driver Assist & ADAS Problems

The full self-driving (FSD) stopped working although it was fully paid for at the time of vehicle purchase. Along with that, the car stopped receiving/installing over the air software updates, the lane markings in the display disappeared, and the automatic cancelling turn signals stopped working (requiring me to manually cancel them). I took it to Tesla service and was told that the car needs a new computer at a cost of approximately $2,300. To answer the bullet points above: 1. The main vehicle computer malfunctioned. 2. I paid for FSD for the safety it provides - without FSD, the car is simply less safe in traffic. 3. The Tesla service center confirmed that the vehicle computer has malfunctioned. 4. There was no indication of any kind, until suddenly the FSD stopped working and I noticed subsequently that downloading/installing software updates failed, lane markings disappeared, and automatic cancelling turn signals stopped working requiring manual operation.

After installing Software version 2024.45.25.15 (Full Self Driving software 12.6.2) on my 2020 Tesla Model Y with Autopilot Hardware v3, I experienced unsafe behavior by the autopilot/automatic safety system. On my second drive after the software update, I was unable to engage the autopilot system. Two “Phantom” cars appeared on the full self driving visualization. One “phantom” vehicle was on the left side of the vehicle in my blind spot. A second “phantom” vehicle was shown about 20 feet ahead and 50 feet to the left of my vehicle. (See screen shots). When I attempted to turn left, the automatic lane keep and blind spot warnings took over and attempted to avoid the phantom vehicle. I was able to override the system, but it caused repeated alarms and attempts to move the vehicle back into the lane.

My Advance Driving assist (FSD for Tesla) stop working randomly. Adaptive Cruse control stoped working, forward collision stopped working. Backup camera randomly disconnect when parking. All of this happened right after a software update. I have contacted Tesla several times. They quoted me $2,666.96 to address the issue. Isn't this a Safety feature of the Car Specially when I paid $10,000.00 extra when I purchase the car to have FSD? All of the advanced driving assistance and collision warning stopped working as well.

I have Tesla’s FSD software that consistently tries to enter closed highway ramps where the flags, lights and barriers are clearly marked as “do not enter”. I have reported this to Tesla a dozen times with no improvement or response. I’m sure there will be retaliation for this but I am sick and tired of swerving to avoid a fatal collision. Too many other safety issues with FSD to document.

I had FSD engaged and the Tesla MY was navigating to my sister’s house in Falmouth, MA. My brother was in the passenger seat and witnessed the incident. The MY stopped on a road to wait to make an easy left turn onto another road. There was a vehicle in front of us waiting to make this same left turn. Another vehicle approached at high speed (my estimate is 60 mph) in the opposing lane. With the vehicle in front of me still waiting to turn, my Tesla abruptly pulled left and moved into the opposing lane about 10 feet before I managed to apply the brakes hard. The vehicle in the opposing lane swerved hard to their right to avoid a possible collision and continued on without stopping. It was overcast but not dark out. This is the worst I’ve seen during the past 3.5 years of driving this Tesla MY with FSD. Current FSD Beta version is v11.4.8.1.

This pertains to the new NHTSA recall 23V-838 that forces Tesla to issue an OTA update changing the use of autosteer and attention notifications. Prior to the new update, I would use autopilot to assist me while I change the climate controls or radio station. After the update, this would instantly notify me that I was not “paying attention” which I am. Eventually it would disable my ability to use auto steer. Large all screen in put makes it difficult for me to adjust basic amenities in the car such as climate controls and radio. Since the new update, I felt that my in ability to use autosteer to assist me has made this operation significantly less safe. Not being able to safely make inputs to the car infotainment has made it riskier. Being all screen, there is no tactile feedback to know where my controls are without looking at the screen. In addition, I feel that the additional more frequent notifications has become more of a distraction as I take my eyes off the road to look at the screen to see what issues I am running into. There needs to be a balance between constant notification and ability to control basic infotainment feature.

ChatGPT Subject: Safety Concerns Regarding Recent Tesla Autopilot Changes (Campaign #23V-838) Dear NHTSA, I am writing to express my concerns regarding the recent required changes to Tesla's autopilot system under Campaign #23V-838. While I understand the importance of updates for safety, it appears that these modifications have had an adverse impact on the vehicle's safety and increased the potential dangers of driving. I urge the NHTSA to thoroughly investigate and address these issues to ensure the continued safety of Tesla vehicles on the road. Your prompt attention to this matter is crucial for the well-being of Tesla drivers and the public at large.

Failure of all cameras, gps, and lane keeping system. It is available for inspection. It occurred after software update was pushed to the car. Tesla service has seen the vehicle and says that the internal computer has a fault and needs to be replaced. Yet, oddly enough, there are a lot of identical failures reported in Tesla owner forums. Around the same time as my failure in mid-December 2023. No prior indication of computer failure occurred. And the computer is still operational for items not related to the cameras and GPS. Safety concerns: The rear windshield has limited visibility, which is not an issue when the cameras are functioning. The safety notification when changing lanes does not work without the cameras and sensors. The lane keeping and adaptive cruise control do not work without the cameras and sensors. Tesla should investigate if a software update they sent over the air created the problem with cameras and lane keeping assist.

I am writing to formally file a complaint against Tesla, Inc. concerning a significant issue that has arisen following a software update issued to Model Y and Model 3 vehicles in early December. I am a Tesla Model Y owner, and following this update, I have experienced complete failure of critical vehicle systems including cameras, navigation, lane departure warnings, auto braking, forward collision warning, adaptive cruise control, windshield wipers, self-driving features, and car location data. The malfunction of these essential features not only compromises the safety and functionality of the vehicle but also indicates a severe underlying problem with the vehicle's computer system. The cost to replace the affected computer in my vehicle amounted to $2,400. However, upon reviewing discussions on Tesla forums, I have discovered that this is not an isolated incident; numerous other owners are facing similar failures, with some repair bills exceeding $3,000. Given the widespread nature of these issues and their chronological association with the December software update, there appears to be a high correlation between the update and the catastrophic failure of the vehicle computers. The financial burden of these repairs has unjustly fallen on consumers, although it is my belief that Tesla should be held accountable for these failures, given the direct link to their software update. I urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly. It is critical to ascertain whether the December software update directly caused the failures of the vehicle's computer systems and to ensure that Tesla takes appropriate responsibility for the safety and reliability of their vehicles. This includes compensating owners for the costs incurred due to these failures and implementing measures to prevent such incidents in the future. Thank you for your attention to this serious matter.

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.

Driving on Highway 80, west of Elko, NV. No obstructions on the road, no cars within 5 miles, no animals or birds on the highway. The vehicle aggressively brakes. It did this 4 times with the assisted driving engaged and 1 with cruise control engaged.

I was driving with cruise control on and the car violently hit the brakes when there was no one in front of us. We have noticed this is more common when cresting a hill. This happens at least once every time we are on a road trip. This needs to be addressed. We know we are not the only person having these issues with the Tesla and the “phantom braking”

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!

On July 26 2023, FSD, camera and navigation were working fine untill i was told to update software in my car. Then the next day everything stop working. I could not use navigation, crusie control, FSD, and all cameras. So, I brought in service to check but they could not fix the issue and want to replace car computer which i have to pay for the issue i did not cause. This is unresponsible that i got it from them. I am not sure if this manufacter defect or firmware issue that cause it. But this is not something that i have ability to cause it. Now with this safey recall i could not update software since there is no option for to do so.

I enabled Tesla's auto pilot feature while driving on highway. Throughout the drive of ~200 miles, the car had sudden phantom breaks for four times. It was very dangerous situations and could have easily caused serious accidents.

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.

Under clear conditions while traveling on the highway, if adaptive cruise control or self-driving is used, the car will randomly apply its brakes. The car will quickly lose 5-10 miles of speed, and poses a hazard to cars behind us. In the 7-8 times this has happened in the last two months, there has never been an obstacle in our path. Unfortunately, this has rendered cruise control unusable

Prior to the incident a message appeared in the car indicating that the Lane Departure Avoidance features unavailable - Features may be restored on next drive. TACC was activated on the car. Auto Steer was not activated. The car is equipped with Autopilot only. It was traveling in the furthest left lane. A truck in the center lane attempted to merge into the left lane where our tesla model y was traveling. The car then steered hard left causing the car to be nearly our of control and swerving left and right. We were able to get the car under control, but we nearly were run off the road.

I was on a self driving mode enabled but it’s been raining for a while and I believe it showed the poor weather condition so FSD is not enabled but autopilot was engaged (but not 100% sure about which mode it was) It was around 2am in the morning and was on 580 southbound from Dublin to SFO. I was on the second to the left lane. It suddenly tried to go diagonally to the first lane. (Not like normal lane change but very abrupt almost like making turn 90 degree left) so I tried to cancel by holding on the steering wheel. And then it went out of control and start rotating until it stopped by hitting the center guard rail on the passenger rear side. The car stopped facing backward on the road (on the center shoulder). Luckily it was late night (around 2am) and there were no car behind luckily. I could have dead if another car hit into my car. Tesla insurance of course didn't admin any of this and told me it was my fault.

We continue to experience phantom braking when adaptive cruise control is engaged on major highways. On a recent trip, it occurred three times on I-90 eastbound between Madison and Janesville, WI, and again in Indiana. Our car does not have “full self-driving.” Most of these were relatively mild, but one was so violent that objects in the cabin were thrown around. If a vehicle had been following relatively closely, a collision would have been likely. This seems most likely to happen as we approach an overpass.
