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.

2006 GMC Envoy Owner Comments

problem #1

Jul 012009


  • 50,000 miles


Stabilitrac and/or ABS system engages when not necessary such as driving on dry, straight pavement at highway speeds. Causes vehicle to decelerate suddenly and almost lose control when brakes activate and motor retards. Electrical system also fluxuates (altimeter bounces from low to hi) causing a loss of power with associated loss of steering, lights, braking controls, at any speed. Problem has been increasing (frequency & severity) from July, 2009 to present (Jan, 2010). Dealer shop did stabilitrac tsb firmware upgrade (and charged me) w/O correcting problem, also retested and "could not find anything wrong":battery is new but problem persists. 55,000 miles, mostly highway/improved roads. This occurs every time, literally, the vehicle is moved: 30-40 miles/day. 1/6/10 engine developed "low growl" noise and RPM dropped from ~800rpm to ~600rpm at parked idle w/O any apparent cause. Now idle at start is normal, but within 1-2 minutes drops and remains low with growl noise.
