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.
My sierra developed a noise on deceleration. Took it to the GMC dealer and was told it had a worn cam. $5500 to repair, $7750 to replace engine. I knew that a worn cam would cause lifter noise all the time so that was wrong info. Upon further investigation I found out this truck has active fuel management. What happened was a failure of the system. It should be noted that this truck always had high oil consumption. I deactivated the active fuel management system.
