What owners say
The engine is no good, they say that the knocking at ticking is ok, gm has put out a notice indicating that this is within acceptable limits. If you heard my truck run you would think it was about to fail!
The vehicle make a very loud tap/knock upon start up.
Gmc serria 2002. Our truck has rust on the bumper behind the painted cover. The dealer suggested this is normal and polished it, within one week the bumper showed rust again. The driver's side door is not lined up correctly, the dealer tried to adjust it, the result is the door must be slammed to close it. The motor makes knocking sounds at the start as if it has no oil. The oil has been changed every three thousand miles. The knock started after the truck turned four thousand miles. The dealer told us that gm reports the knock is normal. It is the first time I''ve heard of a gas motor having an intentional knock. We have had the truck this since it was new and have had the dealer do all the regular maintenance including tire rotations and oil changes.
Consumer heard a loud knock in the engine when starting, the dealer was contacted and indicated that the knock was not affecting the durability of vehicle. Nlm
