Took my vehicle to a Ford dealership located in Marlow Heights, MD, for oil change and a slight vibration in the brake pedal when applying brakes at high speeds. Vehicle has 20,500 miles on it. Was advised that all four brake rotors were warped. Complained to Service Writer and was told that it is possible that the vehicle is not being driven enough (although 20,500 miles were driven within 14 months). The Service Manager told me that it is possible that the vehicle is being parked where the weather could be affecting the rotors, meaning that rims have large open spaces and that rain and/or snow could be causing the rotors to warp. Both responses are totally unacceptable to me. Will never take my vehicle to this dealership again, and this will be the last Ford I purchase.
