I've noticed that after driving in the rain and parking the car in the garage, and driving again the next morning, this happens: When shifting to reverse, the car doesn't move (no creep). Then pressing on the accelerator pedal lightly, it then moves but with a fairly loud clunk sound. Perfectly fine afterwards. I mentioned this to Tesla Service and he said its from rust in the brakes??? And its perfectly fine. Does this happen to anyone else? And does it really sound perfectly fine to you?
