Consumer Description

My 2014 P85D model S electric rear motor failed. I heard a loud noise coming from it so I took it in to Tesla and they agreed the motor was failing and needed to be replaced, Cost $6,582.04. If I had driven the car and the motor seized up it while on the highway it would have been catastrophic. I would have lost control as the motor froze the rear wheel. Tesla knows of this problem, has replaced many of them, unfortunately post warranty. They know the seals leak and coolant leaks into the motor and causes the motor to fail. They have made a number of design changes including the latest where they eliminate a cooling branch going through the motor. Prior to this change none of the fixes have eliminated the problem.
