2016 TESLA MODEL S — Problems, Recalls & Safety Data

I am reporting a safety-related defect involving sudden loss of motive power on my 2016 Tesla Model S. During the drivetrain warranty period, the vehicle developed a persistent humming/buzzing noise from the rear drive unit. This noise was documented on video with a timestamp confirming it occurred while the vehicle was under warranty. At the time, there was no loss of performance or warning indicators. Due to the distance to the nearest Tesla service center (approximately 200 miles), the vehicle was not immediately inspected. When I later contacted Tesla Service, the vehicle was approximately three weeks outside the drivetrain warranty. Upon inspection, Tesla advised that the rear drive unit was failing and would require replacement at customer expense. Tesla declined warranty coverage despite evidence that the failure symptoms began during the warranty period. The rear drive unit later catastrophically failed while the vehicle was being driven uphill, resulting in a complete loss of propulsion. Prior to this incident, Tesla service personnel had advised that if the rear motor failed, the front motor would allow the vehicle to operate in a limp mode to reach a safe location. This did not occur. When the failure happened, the vehicle lost all motive power and was unable to maintain position on an incline. The vehicle nearly rolled backward into traffic. Police assistance was required (911 call) to redirect traffic so the vehicle could be rolled backward down the hill to a safe location. A minor child was present in the vehicle at the time. I am aware that failures of rear drive units on 2016–2017 Tesla Model S vehicles related to coolant intrusion have been reported by Tesla service personnel and other owners. This incident demonstrates a serious safety risk involving sudden loss of power and incorrect guidance regarding vehicle behavior during drive unit failure. I believe this represents a safety-related defect warranting investigation.

I was parking the car and gently tapped on the accelerator to inch forward. The car accelerated suddenly, crashed into a concrete sign holder, and knocked down a sign, until I was able to stop it using the breaks. The accident caused $5000 worth of damage that I paid out of pocket to fix, since I assumed I must have made a mistake. However when I got the car back a month later, unintended acceleration happened AGAIN - under the same circumstances. I was parking and inching forward. I tapped the accelerator and the car accelerated suddenly. This time I was able to stop it before causing any damage. At this point, I KNEW that the first accident was not my error, since it had now happened again, and I was 100% sure that I did nothing wrong. I looked up "unintended acceleration - Tesla" and found examples of the exact same thing happening while parking. I looked for a fix, and it suggested changing the mode of the car to "creep." This so far has worked well.

My 2016 Tesla Model S (45,500 miles) is experiencing a complete failure of the Media Control Unit (MCU1), resulting in a total loss of the rearview camera display and defrost/defogging controls. This is a critical safety hazard. The unit was previously replaced by Tesla in 2021 under NHTSA Recall 21V-035. However, this replacement part has failed again after only a few years of low-mileage use. Tesla Service is refusing to provide a free repair or a goodwill discount for an MCU2 upgrade, claiming the 'recall repair' only had a 1-year warranty. It is unacceptable that a safety-critical component replaced under a federal recall fails twice in 45,000 miles. Tesla has failed to provide a permanent fix for the eMMC defect identified by NHTSA. By refusing to restore the camera functionality without charging full price, Tesla is knowingly allowing a safety defect to persist. I request an investigation into these premature failures of recall-replaced components
