2016 Tesla Model X Transmission and drivetrain Problems

“The mcu (the car's center screen) would not turn on. The center screen controls everything in the car including all the updates. Since the center screen didn't work, and update was not able to pass through, and it essentially made the car not drivable. The car was in the turn off mode and would not turn on.”

“The vehicle started taking longer to start up about a few months ago. Then the system needed to be rebooted on a regular basis to be functional. At one point the main screen that controls all the safety and visibility features of the vehicle stopped working and the vehicle would take up to 5 minutes to start up.

“While driving on city streets at very low speeds, error messages starting popping up on the screen Vehicle may not restart/Service is required . We somehow made it home by restarting the computer and driving home at low speeds. At freeway speeds, this would have been catastrophic. We were able to make an appointment with the Tesla service center and found this to be due to the battery coolant heater to be internally shorted which in turn was because the large rear drive unit had an internal coolant leak. …”
