I was driving from lufkin to hemphill at 70 MPH. Something blew up, I thought something hit me. Engine died, brakes started, emergency lights came on, and seatbelt locked down, truck stopped, I got out to see what hit me. Nothing! When I got back in the truck a white powder (not smoke) was coming out of the seat belt on drivers side. When seat belt locked down I had to back seat up to get out of the belt. I was lucky that I did not hit someone.

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. The truck runs on all 8 cylinders, is completely quiet and no longer uses oil. It is better than new. I also found hundreds of complaints similar to my and paid for expensive repairs. This active fuel management is nothing more than a scam to falsely increase fuel mileage and to rip off customers when it goes bad. It can be deactivated with a $175 chip.

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
