Selected complaints filed with NHTSA by 2017 Tesla Model S owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2017 Tesla Model S. The contact stated while charging the vehicle at a charge station, the contact entered the vehicle and after a few minutes, an abnormal plastic burning odor was present in the interior of the vehicle. The contact noticed white smoke coming from the front of the hood of the vehicle. The contact exited the vehicle and unpluged the charger from the vehicle and waited a few minutes for the white smoke to clear from the front of the vehicle on its own. No warning lights illuminated the vehicle, and the only message that appeared on the vehicle monitor was charging was almost complete. The vehicle was towed to a local dealer who diagnosed the failure as the fan condenser had overheated and it would need to be replaced. The vehicle was repaired, however, the contact had not picked up the vehicle from the dealership at this time. …

Here's a clear, professional paragraph you can use for your NHTSA report: While using Tesla's Auto Summon feature in a controlled parking environment, my vehicle (2017 Tesla Model S) made unintended contact with a stationary garage pillar. At the time, I was actively supervising the vehicle as required, and it was operating at low speed. The vehicle appeared to misjudge clearance while maneuvering, resulting in a sideswipe to the front passenger side and damage to the side mirror. This incident posed a safety risk as the vehicle's automated steering did not maintain adequate distance from a fixed object, which could present greater danger in tighter environments or near pedestrians. There were no warning lamps, alerts, or abnormal sounds prior to the incident to indicate an imminent issue. No emergency crews responded, and there were no injuries. …

The contact owns a 2017 Tesla Model S. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the contact was informed by the dealer, that the computer needed to be updated from Media Control Unit 1 to Media Control Unit 2 to receive proper software updates. The contact stated the vehicle was using the latest autosteer computer software however, the infotainment was using on the Media Control Unit 1 computer which was no longer receiving software updates or safety updates. The contact stated that the computer was able to receive updates, however, the manufacturer chose not to write codes for the older computers due to the cost. The vehicle was not updated version 2022.8.10.16 to the necessary version 2023.44.30 or later due to the cost. The approximate failure mileage was 91,840.

While in autosteer, I pressed on the brakes which normally deactivates the autosteer while coming to a stop. In this particular case the car did not brake upon command and the car maintained acceleration thru a stop light and veered into a median causing a collision with a curb causing structural damage to the frame of the vehicle. I have put in a claim with both my insurance and Tesla and advise that the brakes did not activate in a timely fashion upon disengaging from Autosteer thus causing the collision and was advise by Tesla that I would be responsible to cover the damages when the accident was caused by the vehicle not disengaging. I was only advised after the fact of the recall for the very reason I complained to Tesla in the first place and have been waiting 5 months for a resolution.

The car had multiple computer issues causing it to break unexpectedly, turn unexpectedly, avoid things that were not there unexpectedly. It was brought into the dealer multiple times, who actually viewed the error, and when they were driving it, they were involved in an auto accident. Even with the warranty, they could never fix it, and it was amazingly dangerous almost killing me several times.
