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.

problem #1

Sierra 2500 SLT 6.6L Diesel

  • Automatic transmission

While engine is cold before reaching normal temp, engine seems to be a lot louder than normal. After normal temp is reached it quiets down. Its has exceptional power though. It�s a Duramax diesel and these engines are known to be quieter than other diesels. I have just purchased the truck recently and have had the oil changed also.
