Lifters failed at 98,000 causing engine replacement.
The contact owns a 2008 GMC Sierra 1500. While driving approximately 40 mph, the vehicle lost power. Also, the traction control, service engine, and reduced engine power indicators illuminated. The vehicle was taken to the dealer (betten baker Buick, 2901 28th st, grandville, mi, 49418, phone number: 616-530-9191) where it was diagnosed that the throttle body needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that there was no recall. The contact was referred to NHTSA. The failure mileage was approximately 96,000.
Driving and the engine began making a hitting sound as if someone was beating a metal object against metal.
On 04. 12. 2014 after going to the store, parked under the carport. The time was 10pm. While inside heard a pop sound around 10:15 pm. Went outside and the truck was on fire. Put truck in neutral and pushed it from under the carport, trying to save damage to the house. Fire dept came and put the fire out. The fire warped all the vinyl under the carport. Lucky it didn't catch the house on fire. The fire was worse on the passenger side of the vehicle.
Driving and warning came on and it said "engine hot a/c turned off" had this vehicle only one week when this happened, towed back to the dealer the said wasn't under warranty, I told them to keep the truck. They put on a new thermostat, two weeks later same thing. Took truck to my mechanic and he replaced the thermostat. Good for about two months, warning keeps coming on. Looked on line many people have had this happen, a mechanic at a Chevrolet garage told me it is probably in the cluster panel/ computer?? big money. With all the problems other's have been having, I think it is dangerous truck catch on fire going down the road. Would like an answer to this problem. Thank you mary ann.

Vehicle was in (d) drive and I was able to turn the ignition off. Is this normal? I checked with my GMC dealer and they said it had to be put on the computer to be checked, however was not covered by any posted recall. Is this relative to the ignition recall? thank you.
