The contact owns a 2005 GMC Envoy. He stated that the headlights, dashboard lights and rear lights shut off while driving approximately 35 mph or various speeds. The high beams immediately activate when the headlights shut off which distracts drivers. The failure mileage was 28000 and the current mileage was 58000.

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"

At various time, especially when depressing the brake pedal, the headlights and interior lights dim. GM knows about the problem - tsbs 05-08-42-001 and 06-06-03-004 but does not have a fix. This is a safety issue and needs to be addressed. Updated 10/23/07

Envoy 4WD 6-cyl

  • Automatic transmission
  • 35,000 miles
: the contact stated while driving uphill at no particular speed, the engine stalls and operates at a reduced speed. Additionally, the headlights intermittently work at night and the gas gauge provides an incorrect display of the proper fuel level. Although the vehicle was seen by a dealer numerous times, the dealer was unable to duplicate the problem. The consumer stated the electrical system is faulty. The left front window dropped the lights became dim and the battery failed. Updated 04/06/06.
