Engine problems of the 2001 Chevrolet Silverado

Engine dies without warning while driving, and steering becomes difficult. It happens most of the time when slowing and turning. No error codes appear. Took to the dealer, they have had it for 4 days, and can't duplicate the problem. Changed fuel filter, but did not change problem.

Clunk , squeak, or squawk when coming to a stop and starting up.

Last year my truck started developing a pause in the engine. I had my local dealer investigate the problem. They stated the fuel injectors needed cleaned so they put in an additive. They stated that the problem was normal after 15,000 miles. A little while longer my wife was driving me to the airport (two hours from my home) during the trip the truck started making the same noise and having the same hesitation problems but with a little more vengeance. When we arrived a the airport we had turned the vehicle off so that I could unload my travel bags. My wife tried to start the truck to leave and could not get it going. I had to leave to catch my flight leaving my wife at the curb with a defective vehicle. I did give her the information for roadside assistance. She contacted roadside help and the truck was towed to a local dealer. They were not able to get the vehicle started and fixed so they got my wife a rental and arrangements were made for the dealer to fix the truck and I would return after my trip to pick it up. During the time I had been gone I had found out through my wife that the dealer felt there was a cracked block and would have the truck fixed for me. On my arrival back in indianapolis I made my way to the dealer. Thinking I had a somewhat new engine. In fact I was told that their prognosis was wrong and that it was just a oxygen sensor that had failed. It was good as new! well here I am not even a year later and having the same problems. This time with all three kids and my wife in the truck and returning from toledo. 30 minutes on the side of the road at night, until it started and limped it home.

The engine valves wore out prematurely, the dealer replaced the valves, however the problem recurred.

Flywheel cracked on new vehicle.

Engine stops instantaneously without warning. Extreme safety problem in heavy traffic as power steering is lost. Crankshaft position sensor has failed in both instances.

Consumer contatced dealership for a knocking in engine compartment. Dealer engine piston were the incorrect size. Please provide further details.

Cold start knock or piston slap. My 2001 Silverado 6. 0l sounds like a diesel when I start it up. Problem began at 11,000 miles. Now have 18,400 miles. - piston slap is louder and more persistent. Gm has acknowledged problem, issued service request #, but no service and no response. Very disappointed in gm customer service and product. Gm should remedy huge engineering mistake and fix these engines or buy vehicles back!.

We purchased our 2001 Chevrolet Silverado 1500 new. Right around the 15,000 mile mark we noticed a slight tapping in the engine. This seemed to only occur on start up and mostly in the morning when cold. It would tap for several seconds and then dissipate. Initially we thought it was a lifter, but we have since come to find out it is not. The overall diagnosis is gm piston slap. This occurs when the pistons are ill fitted to the cylinder walls, and hence you get the noise. We were told it was nothing to be concerned about. Gm knows of the problem (well they don't call it a problem), but refuse to do anything about it. They say they have tested these engines thoroughly and the piston slap causes no long term engine problems. The noise not only began to get louder, but also became non stop. It did not go away, and now we have to listen to it all the time. After repeated trips to the dealership for recording of this problem, we still have no resolution. And they have now put us off long enough that the factory warranty has expired. I must say that gm knows how to give you the run around. There is even a website dedicated to this such problem. .

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.

I have had an engine knock on my vehicle since right after purchase. Dealer says it is normal, but refuses to guaratee resale value, etc. This is widespread-why no recall or at least a guarantee of trade in value?.

The consumer was told gm would have new pistons in 02/2002 to replace the defective piston slap in the engine. In 10/2002, he was informed the pistons were normal.

Engine loses oil. In March engine lost two quarts of oil in 900 miles. At 49,000 miles rings and pistons were replaced. Currently, engine is smoking.

While driving tailgate cables snapped. This caused the tailgate to come, crashing down. Consumer was able to keep control of vehicle. Also when starting the vehicle there was a severe engine knock.
