general problems of the 2008 Chevrolet Silverado

The contact owns a 2008 Chevrolet Silverado. The contact stated that while driving 10 mph, the accelerator pedal was depressed and became stuck causing the vehicle to crash into five other vehicles. The key was removed from the ignition in order to stop the vehicle. A police report was filed and no injuries were reported. The vehicle was towed to an independent mechanic. The mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 42,000.

The cab to operator communucation started slowly diminishing. Eventually all audible beeps, dings and music on the left side of the cab were shutoff. The speed control cruise was not activation, but the button would light up. Currently the left side of the truck, in the cab, is out of power. I am concerned, does this affect the air bag system too? the truck does a self diagnostics monthly and no issues were noted, but they were obvious issues that a diagnostic should have picked up a noteable change. The lighting issue I experienced were with each taillight. I would randomly blow tail light bulds. A closer look showed corrsion and obvious shorting, but no fuse was faulted. Buld was burned at the connectors. Further review it was noticed taht each tail light had water in the bottom. Traveling cased the water to short out and damage the bulb, leaving me with no rear lighting randomly. I have since drilled holes in the bottom of each tail light as there is not way to remove the moisture. I have also inspected the bulb seals and find they are firmly pressing on to the sealing surfaces, which are clean and free from road dust and grime. . . Plus they are hidden inside the body of the truck. In summary, I would like to receive some level of detail regarding the electrical issue, focusing on how it can be repaired. Regarding the lighting, this is concerning and should be a consideration for risk assessment during design.
