Vehicle registered "reduced engine power" while I was on the highway, I was able to get to the shoulder, online research showed numerous incidents involving the throttle body sensor and the wires crimping, there was something about the wiring harness being coverd by gm but it does not appear on a recall list.
: the contact stated while traveling 65 mph, smoke flowed from under the hood. The vehicle was pulled over and the hood was raised. There was a fire in the fuse box that was extinguished with water. A police report was taken. The vehicle was towed to the dealership where the entire wiring for the vehicle was replaced. Once the contact took possession of the vehicle, the warning lights illuminated and the audible warnings buzzed. The vehicle was taken back to the dealership who determined there was a short in the wiring system, but there was no repair.
