What owners wrote
I had purchased my sierra 1500 from chesrown dealership of delaware ohio. I had the truck for less than 60 days. I loved the truck very much but was very upset when an electrical fire started in under my hood. This happened the day after thanksgiving and since I had the factory stereo system I had no explanation for the start of the fire.
