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.

The contact stated while driving, the reduce power engine and oil pressure low, check engine ights illuminated. The vehicle stopped, although, the enginewas still running. The dealership was unable to diagnose a problem, but replaced the tank gasket, gas pedal, and computer chip. This caused the contact to rear end another vehicle.

Safety problem regarding control of driver's rear view mirror on 2003 GMC Envoy. There had been a strange combination of electrical events centered around the accessories in the left front of the vehicle and the left door mirror. Other problems: The seat would move erratically when starting and shutting down, the driver's side door did not lock in sync with the others, the locks would click 4 times after driving one mile, and the control button lights on the drivers arm rest was coming off.

Problems with the software. Driver 1 and 2 remotes dont always work. Mirrors change by just unlocking. Sometimes the electric seat release puts the seat into driver 2 position. Transfer case on occasion, all lights start to blink and you can hear the transfer case switching.

Purchased a 2003 Envoy XL on 27 Dec 02 - since that time it has been to the garage two times - no clamp on one end of the power steering line (luckily it blew off while still in our drive way - god help us if it had let loose at high speed on a crowded highway) second time was for a bad cam sensor. And we haven't made the first payment yet. First cass number from GMC is S1-68773551 - second case number I don't have yet as I just reported it this morning. Needless to say that my wife and I have no trust in this car now - what else will go wrong next.
