I am hearing a grinding noise when changing from reverse to drive, but this only occurs when the car hasn't been driven for a couple of hours. After driving for a short time I dont hear the noise when shifting from reverse to drive. I took it to the dealer to get it looked at, initially they thought it might be the transmission, but after inspecting further, they concluded it was normal. Car has around 500 miles. Here are two videos demonstrating the noise. Has anyone else had this issue or know where it is coming from? This really doesn't sound normal to me.
