Owner reports
Selected complaints filed with NHTSA by 2018 Tesla Model 3 owners, lightly cleaned up (personal details are redacted by NHTSA).
On November 30 at 6pm I was driving north on I-75 in the Tampa area with Navigate on Autopilot activated. I was in the middle lane, it was dark, and there was lots of traffic. My screen asked me to confirm the autopilot request to move to the left lane. I tapped the stalk to confirm. I did not look in the left lane and was not controlling the steering, though my hands were on the wheel. The car immediately turned into the left lane and side swiped a police vehicle. Nobody was injured and the damage to both cars was minor. Previously I had received alerts that my left pillar camera was "blocked", but the alerts went away, so I assumed that there was no problem. When the alerts appeared, auto steer was deactivated, but when the alerts went away auto steer worked again. I do not remember when the first alert appeared, but probably earlier in November 2021. …
While slowly backing out of a parking space, I tapped the bumper of another vehicle in the space directly behind mine, causing some damage to the bumpers of both cars. The backup camera on my vehicle was not functioning at the time, making it difficult to see. I have attached a screen shot of the Tesla's display immediately after the accident. You can see the blank feed from the backup camera (there is a reflection of the vehicle next to mine). I have had intermittent problems with the backup camera showing as black on the screen (except for the two lines indicating the direction of the vehicle). Tesla initiated a recall in December 2021. see https://www.tesla.com/support/model-3-trunk-lid-harness-retrofit for details. Every time on my Tesla phone app about this recall, it says, "you do not need to request an appointment at this time. …
The Tesla was parked and locked unoccupied with all security features enabled. When I returned to the car the front driver's side was completely crumpled with the bodywork torn , like it was reveresed in to. I was gone about 30 minutes. The car gave no notification on the app, the car alarm didn't activate and the sentry mode did not record the incident. All the things they say the car will do. I called Tesla and was told it works 99% of the time ,(but clearly when you need safety and security it doesn't) they stated that if the car gets hit a certain way it can cause the system to shut down /reboot ,so that none of these systems work... Seems wrong that this can be allowed to be the case that not only all the systems fail, that when they do fail there's no backup or way for the car to know something is wrong. …

The contact owns a 2018 Tesla Model 3. The contact stated while driving at approximately 35 MPH, the Front Passenger Safety Restraint System (FPSRS) fault warning illuminated. The contact continued driving and later contacted the manufacturer. The contact was advised by the manufacturer that he had the option to repair the Safety Restraint System by a mobile technician or the vehicle could be driven to a dealer. The vehicle had not been repaired. The contact stated that the Restraint System fault warning failure was intermittent at first but had become a recurring failure. The contact researched online and related the failure to the FPSRS wiring located under the seats, which was being damaged by the seat auto adjustment feature. The seat adjustment feature moved both seats to an upright and back position to allow ease of entry of the driver and passenger. …
The contact owns a 2018 Tesla Model 3. The contact stated that when the vehicle was started, the GPS failed to function as intended. In addition, the "Unable to Charge" warning light was illuminated.

The contact received notification of NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention), 23V838000 (Electrical System), and 24V051000 (Electrical System); however, the dealer stated that to perform the upgrades, the contact needed to purchase a new computer before the software could be updated. The contact called the manufacturer and was informed that it would be necessary to complete the updates. The contact stated that the manufacturer was unreasonable in determining that to complete the software updates that he needed to purchase a new computer. The contact stated that the back over prevention camera image intermittently was blank. Additionally, the on-board cabin camera ceased to function as needed, causing the autosteer feature to become inoperable. The failure mileage was approximately 130,000. …
The contact owns a 2018 Tesla Model 3. The contact stated that there was a feature in the vehicle that allowed the front driver's seat to automatically adjust according to the saved driver's profile. The contact stated that the driver's seat back and forth movement to adjust to each driver's profile might have caused loose wire connection, resulting in error code: RCM_a021 (Front Left Safety Restraint System Fault) being displayed. The contact stated that the error message had been displayed intermittently. Upon investigating the failure online, the contact related the failure to the seat adjustment feature. The failure was reported to the manufacturer through the Tesla App; however, the contact had not yet received a response. The vehicle was not diagnosed or repaired after the failure. The failure mileage was approximately 55,000.
The contact owns a 2018 Tesla Model 3. The contact stated that while driving 60 MPH with the Self Driving feature activated, the vehicle failed to slow down while approaching oncoming traffic.
