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!

Dealer advised that the dealer installed remote starter or alarm system was interfering with fault sensor and was not a problem. However the lost power while driving, intermittent surges and stall outs at freeway speed/85 MPH still existed. On one occasion consumer was almost in an accident when the transmission clanged between gears and there was poor acceleration. Consumer had to shift into 4 wheel drive or manually downshift, or turn the engine off then on again. Dealer replaced PCM module, fuel pressure regulator and gaskets, fuel pump assembly. However problem still exist. Dealership agreed to hold the vehicle for further investigation. Further investigation revealed that the wires from the dealer installed accessories such as the alarm system and remote starter or anti-thief system, and factory wire from PCM/vcm to the transmission be replaced.

Every 2000 miles the vehicle burned a quart of oil, the dealer stated it was normal.
The vehicle stalled, which made it difficult to control the vehicle.
The vehicle displayed hesitation when idling and driving any speed.
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 complains of premature stalling at idle. The vehicle lacks sufficient power, it surges and at times refuses to accelerate. The transmission doesn't shift down properly out of 4th gear and the air conditioning unit does not cool properly and makes whistling noises. *jg
On cold starts the engine produces loud rapping sound as if running on no oil. Gmc has been notified, but it is deemed a normal operating sound, and will not shorten the engine life. They never made any attempt to fix problem, just offered an extended warranty on certain parts. It really makes me wonder how they know what parts to cover on the extended warranty if there is nothing wrong with the engine? Dt
No summary listed for above vehicle.
The oil light illuminated after 2500 miles. The consumer found out that the vehicle had consumed over 2 quarts of oil and emitted blue smoke when started cold. The dealer replaced the pcv valve as a cause but the vehicle continued smoking and consuming more oil, the dealer informed the consumer that eventually they would have a redesigned valve cover to prevent the problem, but that they could do no more at this time.
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
Vehicle stalls on take off, dealer cannot remedy problem. *ak consumer states the problem of the vehicle stalling was solved by using high octane gasoline. The clutch does not engage properly, also sometimes sounds so loose.
