While changing a blown fuse for the instrument cluster, my truck unexpectedly caught fire, endangering my safety and causing significant damage to the vehicle. The fire started behind the passengers side fuse box within the wiring harness (GM# 84717166). The dealership determined that the failure was due to wire harness chafing on the thread side of a tie bar bolt. Due to General Motors not responding to their request for repair information via the TAC, they concluded that the bolt needed to be shorten in order to reduce the chafing. There were no warning signs or indications that this was going to or could occur. The burnt harness is available for inspection but the vehicle has been traded in due to no longer trusting how it was manufactured.

The message went off and cleared. we resume going home on our trip and we are 14 miles on the highway then we got off on our exit there-??s no lights or no problems with the vehicle. I dropped off the first passenger and Lexington, Ohio, and then the second passenger lived about a half mile away, this time kept unloading their equipment. From Lexington to my home in Mansfield, Ohio the other passenger I was talking about the light transmission was weird and might-??ve been just a sensor. As we pulled onto Home road all the panel lights started flashing and then a message came across and said engine is shutting down. I put in park off the engine, we exit the vehicle and smoke was coming out from underneath the truck. I reached into the center council to grab the cell phones and had faster call 911 and when I reached back into the truck were coming out from underneath the hood. I notified General Motors on September 23 and have been battling them to get an inspection done. after several months, they have finally agreed with insurance company on terms to investigate what caused the fire.

While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.

The trucks installed trailer wiring can cause a traffic accident. The wiring harness is known to have electrical issues but is not being corrected under warranty. It is difficult to know of these issues until you hook up a trailer or camper. The trailer's brake light and turn signal are affected by the faulty wiring. The dealer narrowed the problem to being between the plug and fuse. Other people have voiced their concerns with the trailer wiring.
