The hatch continues to fail even after they replaced "defective" part. The batteries had to be replaced because they had failed. On 3/2/17 I was sitting in the driver seat with the car in park with the engine running and suddenly the driver seat moved all the way forward, then the back straightened completely and the side view mirrors adjusted all the way up. I placed a call to the dealership at 2:51pm, was told I'd get a call back. I drove the car home with my adult daughter. Radio was off. When I was stopped in either traffic or a light we could hear a motor trying to start. I made it home safely. I had the car towed to the dealership and was advised that since they could not replicate the problem it didn't happen. They returned the car to me without any documentation of a complaint.
