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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2001 Chevrolet C/K 1500 Owner Comments

problem #1

Apr 112007

C/K 1500 LS 4.8L

  • Automatic transmission
  • 70,000 miles


I have the same problem as the others listed. Knock on cold start-up that lasts 2-3 minutes. Truck has 91,000 miles on it and I first noticed this problem at about 65-70000 miles. Been on several forums, changed oils to synthetic 5w-30. Changed filters.

Have had a few other minor problems with this truck, other wise it has been a good truck.

Have not had it to the dealer that I bought it from because they have shrugged off every other problem that I have ever had with this vehicle so I have not been back nor will I be. This is my 3rd and last GM truck!!!!
