The rear view mirror in my mustang vibrates on any road with imperfections so that you cannot distinguish what type a vehicle is behind you. i have had it replaced under warranty, but the new one does the same. this issue is on a majority of mustangs, according to forums, and i believe it is a safety issue if you cannot distinguish if there is a safety vehicle behind you.
Wipers are very noisy and have been since delivery of the vehicle from the dealer
