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.

Envoy 4WD 6-cyl

I was driving about 25 miles per hour @ night when all the warning lights on the dash came on and all the gauges read zero except the speedometer and tach, transmission gear selector wasn't indicating what gear I was in & radio also killed. Headlights, wipers & directions were still functional. I only had a mile to drive to get home. Parked vehicle in garage and shut off....only to discover that power locks had failed and I was locked in car, power windows were also out! removed key from ignition and fortunately the remote key fob unlocked the door. Had this been an emergency situation, I would have no way to exit the car nor would any passengers. Anyone else having this problem? I contacted dealer to apprize them of this new problem and was advised that if it's intermittent they would have problems fixing it. The vehicle seemed to reset in the morning and all dash warning lights back to normal!

The contact owns a 2005 GMC Envoy. The contact stated that the vehicle failed to shut off and the heater fan continued to operate. The contact had to unplug the battery terminal in order to turn off the vehicle. In addition, the contact noticed that the fuse box was melted. The vehicle was taken to the dealer. The technician replaced the fuse box and other parts that were damaged; however, the failure persisted. The contact stated that the vehicle failed to start on the first attempt and the gear shift would not shift gears. The vehicle had not been repaired. The manufacturer was not notified of the failures. The failure mileage was unavailable.

Repeat problems since car was purchased brand new at dealers. Air /O2 sensors defective/replaced. Defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. Tie rods both replaced as well as both front sway bars. Immediately following vehicle purchase, check engine light would continuously go off. I would call onstar at which point I was told to take car in for repair w/I 7-10 days (often told a problem w/powertrain or transmission). At dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, I began to disregard the light as I was in the dealership almost weekly. Approx 2 yrs after purchase, filled up gas tank and fuel light showed "low fuel". went back up to full, dropped to 1/2 and back to empty. Went back to full after car was turned off and continued to do this. After about 2 weeks, constantly stays at empty. Called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which I could not afford and began to track odometer and refill tank after 200 miles driven after fill up. Have been doing this for 5 years. Jan 29,2011, I go for emission test. Fail D/T low fuel and check engine light being on. Go to mechanic, approx $950 repair. Check engine light goes off...and back on next day. Read thousands of posts online and am finding many, many Envoy owners experiencing same problems as mine. These are safety issues and GM should issue a recall on entire fuel and electrical system. Please call for questions/clarification.

Car switches into all 4W and higher by itself. I had been to a dealership 3 times in one year for which they were unable to find the problem. Now my warranty is up. After that I took it to a transmission shop where they supposedly fixed the problem for over 800.$ a week later it did it again. Now I have the 4WD disconnected for safety reasons. I would be driving on the freeway at 60-75 mph and if would switch and not come out no matter what I do. I have owned this vehicle for almost 5 years and it has done this the whole time. I am a single mom and I drive my 17 and 7 year old around in this car. Even with it disconnected it still tries to switch. There is no specific time, temperature, or other reason this happens. It has happened when I turn on the car and sometimes I can go a couple of weeks and other times it happens daily. I also have had my lights not go on for no reason and also the doors lock and can only be unlocked by using the key. And the hatchback will not open at all when this happens. Electrical?? help!!

I have a 2005 GMC Envoy. I am having problems with my shift lever; it goes in park and stays there for about three minutes before it releases the key (to be taken out of the ignition). When I start the truck, it will not go into any gear for about three minutes, then I hear a click which then release the shift so it can be moved into another gear. It began about two months ago and has gotten worst over time. Once in any gear accept park it can be shifted to another gear without any strain. The consequence of this problem is not being able to get out the vehicle with my key once in park until after the lever cable "snaps in place." I have not been able to do much of anything about it thus far due to financial difficulties.
