I was at 60 to 65 MPH on an interstate and the truck powered the motor down. The electronic stability control module light came on and the service engine light. I was able to get off at the last safe exit for quite a way. Onstar recommended not driving it to the dealer. The dealer did the diagnostic and at 28000 miles told me it was the throttle body assembly. It took 5 days to get a "new" one.( aprox 1/26/11) on aprox 12/15/11 an almost identical thing happened, mileage 50,000. Out of warranty I took it to a local shop. Their computer test concluded a throttle body assembly malfunction. $450.00 to repair. Call the dealer " no that is under warranty" dealer concluded that it "just needed cleaned". Prior to service (I rely on this truck for work, I can not get a ride, I can not ride a bus) I was able to "reset " the stabilitrack ( the button would not turn it off) by pulling 4 fuses under the hood fuse block. But boy when it had enough the truck would power the motor down and within 15 seconds the truck would die right where it was. 5 MPH, or 15 MPH no power nothing, brakes ,steering gone.

Tl*the contact owns a 2009 chevrolet silverado 1500 crew cab. He stated the passenger's side power door locks failed. The dealer replaced the lock actuator under factory warranty. Later, he could smell a burning smell, similar to burning plastic, from inside the vehicle but could not determine the source. On a later date, while getting out of the vehicle, he noticed a two inch burn hole near the driver's side door handle. The dealer was contacted and advised replacing the door handle. The dealer could not provide a reason as to why the burn hole was on the door. The dealer found there were wires that failed and overheated, causing the damage to the door. Repairs were made to the door and the lock actuator was replaced a second time, under factory warranty. The failure and current mileages were 13,310.
Vehicle caught fire after being parked for 2.5 or so hours in driveway. Determined by fire marshall to have started from a ECM in right front dash area. Fire department responded and extinguished fire with water instead of foam because "foam tank was not operational at that time". No repairs have yet been made to the vehicle due to outstanding insurance investigation.
