Our MKC is experiencing a new problem that started today. The sound coming from the stereo speakers (AM/FM/Sirius) sounds weak and tinny. It sounds as though the amplifier is not working properly. The radio seems to have no midrange or bass. I found the amp in the back of the car by the spare tire and it was warm to the touch. Has anyone experienced this type of problem? Will contact the dealer for an appointment in the coming days. I am growing tired of the reliability and lack of quality of some of the cars components.
