ELECTRICAL SYSTEM

1 complaint

While driving, a fire started inside the vehicle between the rear passenger side seat belt and the rear window. My daughters were in the back seat and started screaming. I immediately stopped the vehicle and ran to put the fire out by smothering and throwing water on it. There was zero warning...no lights or warning messages. No major injuries occurred (only small minor burns to my right hand). I then brought the vehicle to the dealership where it was purchased. I was told it was a known issue, and I was prompted to file a claim with my insurance company. Someone from the insurance company, along with the service department at the dealership, inspected the vehicle. Insurance has agreed to cover the parts damaged but not replace the part(s) that actually caused the fire. The dealership will address the actual problem, but only if I pay for the repairs ($1100-1500 estimated cost).

The rear camera and wire harness for the Rear Backup Camera became corroded and stopped working months ago. This is vital technology that our children have grown up with to ensure the safety of backing up in case something is behind the vehicle including young children, toys, equipment or someone simply walking by your driveway while you're backing up. The Service Manager at Billion GMC in Sioux Falls, SD (Dan Dunnagan) said they are replacing tons of the rear cameras due to corrosion, which might be caused by water getting into the system or faulty parts and faulty wiring from the product manufacturer. This is certainly a safety issue. I had it repaired at a cost of $591.84 for the rear camera and wire harness plus labor. This issue on GMC Canyon and Sierra 1500 pickups should be investigated as the Rear Camera is a vital piece of safety equipment and if a large number of these are faulty, subject to corrosion or poor manufacturing, it should be brought forward to protect consumers.

AIR BAGS,FORWARD COLLISION AVOIDANCE

1 complaint

I was involved in a MVA with another car. The other car had all their airbags deploy after they struck me. None of my airbags deployed. I was hit in the right front corner ahead of my right tire. The secondary impact was to my right side between my rear passenger door and rear tire. They hit me with enough force to bend the frame of my truck, crack my engine block and the appraisal from the repair shop came to over $34K without any engine work. I was the only one in my vehicle, thankfully. I am not sure how many occupants were in the other vehicle. But they were transported to the hospital by ambulance. My wife took me in our other vehicle. I was diagnosed with a concussion, assorted bruises, aches and pains. What troubles me is that while my airbags didn't deploy, the other vehicles did! I was spun 90* to 180* from the way I was traveling. (I don't recall any portion of the accident, I was planning on making a right hand turn and I ended up the opposite way from the way I intended to go. I fell that there was sufficient force involved to have my airbags deploy and I did contact GMC to make them aware of it as well.
