Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Silverado 2500

  • 60,000 miles


The contact owns a 2001 Chevrolet Silverado 2500. While driving 65 mph, the vehicle suddenly shut off. The contact was able to restart the vehicle and drive 3-4 miles before it shut off again. The vehicle was taken to the dealer and they stated that the camshaft position sensor needed to be replaced. The contact did not notice any differences beforehand. The current and failure mileages were 60,000.

: the contact stated at various speeds, the vehicle stalled without warning. The vehicle restarted every time the engine stalled. Also, the check engine light illuminated and the vehicle was taken to the dealership who determined the crankshaft sensor would have to be replaced. Updated 9/13/2006 - the crankshaft sensor was replaced but that did not correct the stalling problem. The check engine light did not come on the last time the vehicle stalled.

Contact states while driving the battery light will come on, and then the engine completely loses power, but does not lose the electrical power. There are no indications, such as the engine hesitates before the vehicle stalls. This happened on numerous occasions. The service dealer can not find what is wrong with the vehicle, but they have not checked the charging part of the vehicle. The owner's manual states it could be something wrong with the charging system. The vehicle has to sit and wait for approximately 3-4 minutes before it will restart. The vehicle has been to two different service dealers, but they cannot duplicate the problem. The consumer has contacted the manufacturer.

In June 2005 the consumer's truck stalled. While driving at highway speeds the engine stalled with a total loss of power steering and brakes, no warning lights. The vehicle operated normally before this occurred. There are no other apparent problems with vehicle. It is regularly serviced. The problem seems to be getting progressively worse.

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.

Complaint on 2001 Chevrolet Silverado extended-cab. The vehicle made a knocking noise when it was first started or after being fully warmed up. The consumer took the vehicle to the dealer and was told that GM was fully aware of the problem and that they were in the process of re-designing and manufacturing a new cylinder piston for the engine because it seemed the pistons were causing the problem. The consumer was informed that a combination of a timing adjustment or decarbon of the engine or valve adjustment would possibly take care of the problem for the time being, however the consumer stated the engine noise became louder. The consumer took the vehicle back to the dealer and this time he was told that GM stated the engine noise was normal.

  • Automatic transmission
  • 15,000 miles
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. go visit, it is some interesting reading. Non the less, GM will do nothing about the problem, so we are stuck with a vehicle that embarrasses us each time we drive it. What a shame, because I really do otherwise like my truck.

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.

While driving at highway speeds the engine shut down and caused loss of power steering. The vehicle was taken repeatedly to the dealer. The vehicle was taken back again and the dealer did not find the problem. The GM technician informed the consumer to not use chevron gas. After GM advised the dealer what to do, the problem was resolved.

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!
