A very loud knocking noise is coming from the motor, we have had the lifters replaced, but it still has failed to correct the problem we have contacted the bbb about this problem we are waiting to see where we go from here.
The consumer states that there is a clattering noise during acceleration/pinging, up inclines and under load weight. And found excessive valve clattering on acceleration and decarbonized the valves, but were unable to resolve the problem. (the vehicle was released with the knowledge that the pinging still occured) the consumer is giving chevrolet the oppurtunity to resolve the problem in a timely manner, and if these problems are not repairable, then he is expecting a refund of the purchase price with interest.

When starting vehicle, whether it's cold or hot, vehicle will make a loud noise that comes from engine. Noise gets worse when getting on the highway. *ak door windows were loose. Dealer states the engine noise is normal.
Vehicle was consuming oil. Engine was making tapping noises. Gauage would always be under normal level. No oil leakage was found on the ground. Dealer would not honor manufacturer's warranty because it was normal for vehicle to burn a quart of oil. Only if it burned a quart of oil would mechanic inspect vehicle.
Vehicle will stall usaually at highway speeds, engine will shut off, after coming to a stop vehicle could be turned back on, consumer contacted dealer and dealer was not willing to do anything.*ak on 10-20-01, the vehicles engine abruptly quit running 3 times while cruising at normal highway speeds, all engine indications were normal with no failed messages, after coasting to a stop, the engine restarted ok each time. On 10-22-01 the vehicle was completely checked by the dealership for existing or previous faults, problem could not be duplicated. On 11-03-01 the same problem again occurred 3 times. On 11-06-01, the dealership was able to determine that leaking coolant tank was allowing coolant to follow wiring harness into the electrical connector on the drivertrain computer unit, causing intermittant fuel injection operation. Repairs were made, problem has not reoccurred.
There is a loud noise coming from enigne. Has taken vehicle to dealer, but dealer cannot find cause of problem.
Tires "cupped" before 8000 mile rotation, transmission- feels like clutch is slipping, has times in nuetral from a stop then slams into gear... Motor sounds like a diesel at start up quiets some, yet all this is suppose to be "normal". *ak (tiresize: 235/75/r16)
I purchased my vehicle and 1 week after purchase the engine began making a knocking noise which proceeded to get louder. I phoned my dealership and they made an appt to bring in the vehicle for inspection. I was told at that time that the vortec engine made that sound and there was nothing they could do. I disagreed as it didnt knock when I purchased it. They did a top engine clean and returned the vehicle. I drove it to wyoming and the same day I picked it up it was knocking and missing. I phoned the dealership and they said to bring it in when I got home and gave me gm cares number in case it broke down. I took the vehicle back in and they have now had it for 16 days. Nothing has been done to repair it . I phoned gm they said 1 out of 4 vortec engines have this problem..they have no fix for it but I should get at least 36 thousand miles from the engine. I told them that was not acceptable I paid 28 thousand dollars for the truck and was told I should get at least 200 thousand miles on the engine. They were aware of this problem before I purchased the vehicle but never disclosed this to me. The transmission is also spinning in gear. I was at a stoplight and at the green light accelerated but the transmission spun then jumped into gear and almost threw the truck into the vehicle in front of me. Also towing my horse trailer the transmission doesnt shift properly.
After only having this new truck for 2 days the transmission was taken out of it due to a ticking noise in the engine. The mechanic was advised by gm to take out the transmission and replace a flywheel. After 2 weeks of waiting for a part I picked up my truck. The next day the noise was back. I have had 2 gm reps listen to the noise. The secound rep told me that it was "entrained gasses" and that there was nothing they could do about it. I did not purchase this truck making the noise and do not want it anymore after the transmission has been taken out.
On 3 of the only 4 occasions I have had to drive this vehicle at 70 MPH for any extended period when outside temperatures exceeded 90, the following symptoms have manifested: loud engine knock sufficient to shake vehicle and discharge of large cloud of gray (not the black as is typical for a diesel) smoke. Numerous cars have driven off the road behind me to avoid the cloud of smoke that obscures their vision (and possibly to avoid parts from a motor they may think has blown up). Vehicle is presently at king chevrolet, tyler, texas for 2nd time (not selling dealer) and had been at one other dealer; lewis chevrolet, canton,texas. Problem has not been diagnosed. Dealers say that gm technicians say problem is unique - no other owners have reported this problem. Problem has been reported to gm which has assigned the complaint file #4913340. At time of this filing, it is unknown what, if any action gmc intends to take. I regard these symptoms as potentially hazardous to occupants of my vehicle. I regard the large and sudden exhaust discharges as being seriously hazardous to other motorists.
Vehicle has stalled numerous times both while driving and while stopped at a light, but problem occurs intermittently. After several tries the vehicle will start again. Dealer unable to recreate problem no solution provided.
Engine stalled without prior warning in stop and go traffic, and engine misfired several time daily. Also, transmission clunked on straight away, a torque converter lock up. Dealership was aware of problem. . Vehicle was there for four times, vehicle is there currently.
6.0 liter engine is making a loud "pecking" and "clattering" noise during normal operation of vehicle. Dealership has examined vehicle, and informed consumer that noise is normal. Consumer feels noise could be coming from valves in engine.*ak
The engine knocks at startup when engine is cold. I contacted gm and I have gone to a local dealer about the problem (not lawson chevrolet which was the dealer I purchased the vehicle from). Neither general motors or the local dealer where of any help. Basically I have been told the knocking at startup is normal.
Contacted dealer;said tsb will be issued;I am making the federal safety agency aware of problem to keep consumers informed of any recalls remeadies or repairs conserning this engine noise.
