NHTSA Complaint #11420946 — 2016 TESLA MODEL S

This model's Main Computer Unit (MCU) is malfunctioning by spontaneously rebooting thereby disabling major functions of the vehicle including the rear camera that is enabled when driving the car in reverse. This is a safety hazard since rear visibility is completely disabled during the reboot of the system. As the NHTSA is likely aware, this problem has been previously reported and Tesla has previously issued a voluntary recall for this problem. It resolves the problem by installing a larger memory chip (a daughterboard) on the main board to prevent these functions from being disabled. My vehicle was included in this voluntary recall and was expedited to receive the recall after I reported this problem (the problem I reported is apparently different from the one that was the main impetus of the recall). However, the installation of the upgraded memory chip DID NOT resolve the problem that I have been experiencing and the safety hazard persists. I was told at the time of the voluntary recall service appointment that this installation would likely solve the problem that I was experiencing but it has not done so. I have reported these results to Tesla and they claim that they are working on a software update to eliminate the problem but they have not provided any timing for the availability of this software update and I continue to experience the effects of the problem on a regular basis. The dealer is aware of the problem and the vehicle was inspected in connection with the voluntary recall. No warming messages are provided in connection with this problem. The MCU also known as the touchscreen in the Tesla simply unexpectedly reboots until the the functions are restored, a process that takes several minutes to occur.
