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.

Check engine light accompanied by engine cut-off when cold weather since November 2009. Twice GMC dealership couldn't duplicate issue and no idea for check engine light. New development of fuel gauge failure each time of gas fill-up accompanied by fluctuating fuel level indicator. Clicking noise coming from gas pedal for 3 years with increasing frequency. Electrical system including gauges, speedometer, power steering noise, cruise control seem to be having issues. Dealership claims no recalls, but electrical issues appear to be common according to forums for GMC Envoy.

Wife's 2006 GMC Envoy heater lights, and high blower quit working, took to corner service station to find out what was wrong and fuse block on heater motor was melted.talked to mike and he said when he opened service book, it told of this problem to check it first, needs wiring harness and fuse block replaced. If it melted together it sounds like a fire hazard, if it is first place to look in repair manual, sounds like its a defective parts problem.

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.

Fuel gauge bounces around even when full with gas. When filled, the gauge needle gets buried at empty with light and sound dinging. Then the check engine light comes on.

problem #1

  • 26,000 miles
The contact owns a 2006 GMC Envoy. The contact smelled a burning odor coming from the vehicle and parked it overnight. The following morning, the air conditioning system would not operate. The dealer stated that there was a heating resistor that melted some of the wires in the ignition system. The wiring harness was replaced and the dealer advised the contact not to activate the air conditioning system on low power; only medium and high due to the power needed by the blower when running on low. After the repairs were made to the wiring harness, the fuel gauge became inoperable on the instrument panel. The failure mileage was 26,000 and current mileage was 27,000.
