Radio/tape Cd Player problems of the 2012 Chevrolet Malibu

The contact owns a 2012 Chevrolet Malibu. The contact stated that the steering wheel abruptly locked while attempting to turn at a low speed. The failure was experienced several times. While the bluetooth was in use, the radio and steering wheel simultaneously failed. The vehicle was taken to the dealer where it was diagnosed that the battery cable was defective and caused the electrical system to lose charge. The vehicle was repaired. The battery cables were replaced and routed correctly. The manufacturer stated that the cable failure was due to wear and tear. The failure mileage was 47,607.

The interior light panel went completely dark, after a few minutes it lit up again. This has been happening more frequently lately. The radio stops playing and the panel reads "auxillary mode"and then back to radio, then back to "auxillary mode". I have to turn the radio off and on for it to start playing again. It is happening more frequently. When I plug in my auxillary cord to listen to my ipod, it shorts out. The clicker to unlock/lock the car stopped working as well, so I went to get a new batery. They tested the battery and said it was fine. Also my rear defroster does not work at all now.
