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 gas tank has a lose connector that leaks and allows fumes to escape.

We have had numerous electrical problems with the Envoy, but I am writing about the instrument cluster panel. The failure of the panel caused the speedometer to fail. The speedometer registers over 120 mph regardless of the speed of the vehicle, or whether the vehicle is turned off or on. The mechanic who investigated the issue stated that there were numerous diagnostic errors that had to be corrected before he could successfully diagnose the bad instrument cluster. This is a known issue with the Envoy, GMC will not accept responsibility and the failed instrument panel can result in accidents.

Dash gauges/ first the oil level gauge died, then the speedometer started acting up, it will say your going 200 mph, when your standing still...then the speakers and the radio started acting up, work, don't work...really concerned about speedometer, and if other gauges will follow suit.
