Extreme rust on undercarriage had broken suspension, brake lines, fuel lines, frame integrity

- Decatur, AL, USA

The 2010 GMC Sierra ld 1500 had multiple premature failures associated with the electrical system. The failure were pertaining to the radio associated with an internal short from the instrument cluster/panel and the drivers side electronic function panel. Months after owning the vehicle, a failure progressed in which the driver was unable to use the function buttons for the windows and unable to lock or unlock the doors from the electronic function panel unless using the key fob to lock and unlock the doors. Only the front passenger and the rear passengers may wind the windows down due to the failure. The driver was only able to wind the window down on the drivers side due to the failure. In addition, the aux function shorted prematurely so when attempting to attach a device, it may or may not connect due to an internal electrical short in which it may not recognize the device (phone, MP3, tablet or ipad/ipod). An abnormal noise progressed from the front of the truck and upon a mechanics inspection, it was diagnosed that the upper control arm needed to be replaced, the drivers side window switch panel and recommended taking the vehicle further diagnostic testing on the internal electrical failures. There was also progression of premature rust under the frame in which the mechanic recommended coating the frame to prevent any further rusting under the vehicle. The vehicle was to be taken to the dealer for further testing and diagnosis. The approximate failure mileage was not available.
