Defect investigations
Loss of Headlights
The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at under the identification numbers in the attached document.

What 2009 GMC Envoy owners say
Most recent owner complaints, unedited.
The transmission I had to have it replaced but the one they put in it is really acting like the other transmission did no reverse and the first 2 gears were making this grinding noise I've never heard before and it happened when I was backing out the driveway to go to work lucky I made it to the place where I got it to fix it but I believe this transmission they put in it is going to do the same thing because it drives just like the old one
For 5 months the headlights work when they want to, the first couple months they were working more than not, last couple months they were not working more than they did work.
Only 8 years old and 140,000 miles the exhaust manifold has cracked allowing exhaust fumes to enter the interior of the car. I have had no accidents with this car and I see no reason why the manifold should crack. I have had cars longer then this that never had this problem. Manifolds should not just crack.
Headlight drive module (hdm) controls both low beam headlights. This relay has failed on me twice in less than a year, at night resulting in going down the road with no lights and unable to see. Vehicle was in motion on a highway going 55 MPH at night
Low beam headlights don't work even after replacing the hdm.
Rear hatch window exploded on its own into a thousand pieces with vehicle parked in mild weather. This apparently is a defect in design that is an unaddressed safety issue.
On december 20, 2015 we were traveling after dark (7:30 pm) and the head lamps went off. We managed to pull out of traffic safely. Could not figure out what happened. After sitting for approximately 5 minutes the lamps came back on and we were driving to our home and the lamps went off again. I took the vehicle to a chevy dealer and they could not help me. I then called the gmc dealer and got the same response. I then checked online and found out that gm knows of this problem which is caused by a headlamp module overheating. I know this problem is occurring to other people so why hasn't there been a recall.? Help.
