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.

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.

Out of nowhere my front head lights went out. Its not the fuse or the bulbs, both front low lights went out. The high beams work. There is no power going to the lights and I have to buy a new switch. I also had to replace the engine almost a year ago because the O rings went up. The gas gauge is broken and my passenger window will not go down. I feel so stuck with this car!

I purchased a 2005 GMC Envoy in September 2005. In the past year (since January 2007, at least), I have experienced several problems with my vehicle. The first problem is with the headlights. Everytime I have driven the vehicle the headlights appear to dim/flicker and then return to normal. This has resulted in oncoming vehicles turning their bright lights on me thinking my brights are on when in reality my headlights are dimming and then returning to normal. The second problem concerns the passenger side airbag. Anytime a certain weight limit is met or exceeded the airbag sensor is supposed to switch to on, but there have been several occasions when someone was sitting in the passenger seat and the airbag sensor hasn't recognized it. Third problem, driver side power seat failure. There have been several instances when I have tried to move the driver seat forward, but nothing happened. The motor sounded like it was grinding and wanted to move, but the seat would not move forward or backward. The most extreme problem to date has been with the vehicle completely shutting off without warning while in the middle of driving and then not starting or even turning over at all. Every single day for, at least, the last month when I go to start the vehicle it fails to start and it takes a minimum of 1 hour to get it started. One instance in particular when the vehicle shut off without warning was while my wife and I were on the freeway. Without warning the vehicle shut down and we were forced to pull onto the shoulder. We sat there for almost an hour in temperatures of 13 degrees trying to get the vehicle restarted. There have been countless complaints and reports of other Envoy owners experiencing these same problems. Some dealers have actually said that these failures/problems are normal!!!! what!"!?! are you freaking kidding me?! since when is it considered "normal" when so many Envoy are displaying these same problems"

2005 GMC Envoy has developed multiple problems. The driver side front seat side cover was coming off and the passenger side front window was inoperative. Both issues were recurrent.
