A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Our customer/insured was driving his 2007 GMC sierra on april 23, 2009 with his child in the back seat, the auto started on fire as he was driving. He was able to get out of the auto with the child before fire reached the interior. The fire started in the engine compartment and traveled throughout the rest of the auto before the fire department could get to the scene. Over 3/4 of the auto was totally burned. Owners name is john czech.
HVAC system became operational with the ignition turned off for an unknown period of time while the truck was parked in the garage. Relay resistor module overheated causing melting of the resistor and circuit board. Truck cabin and vicinity around the truck had a strong smell of burning plastic. Truck cabin filled with smoke. Was only able to turn off the HVAC system and stop the burning by disconnecting the wiring harness. Dealer had to replace the blower motor, resistor, module connector and relay.
The truck after 40 miles started screeching from the front when going around corners,and was reported to the dealer sam swope, I was informed that it was normal, on the way to town the truck stalled and was towed for repair turns out the coil plug shorted out wires were replaced, next day the truck stalled again towed again turns out that booth catalytic converters were plugged,booth replaced.
