Exterior lighting: headlights
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
- Risk
- Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
- Remedy
- GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1‑800‑521‑7300 or Pontiac customer service at 1‑800‑762‑2737. GM's number for this recall is 14291.
Recall number 15V519000 · Recall details
Electrical system: ignition
- What is wrong
- This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
- Risk
- If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
- Remedy
- GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1‑800‑521‑7300 (Buick), 1‑800‑458‑8006 (Cadillac), and 1‑800‑222‑1020 (Chevrolet). GM's number for this recall is 14299.
Recall number 14V355000 · Recall details
Air bags: frontal
- What is wrong
- Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved. Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction.
- Risk
- If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.
- Remedy
- Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, general motors (gm) will repurchase these vehicles in accordance with the terms stated in gm's letter to owners. The recall began on november 6, 2006. Owners should contact gm at 1‑877‑477‑1022 to begin the process of repurchasing their vehicle.

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.

Vehicle rear-ended at high rate of speed. Impact included rollover. Driver was buckled but seatbelt and/or seat failure and no air bag deployment for either occupant. Serious bodily injury occurred. Vehicle on hold pending further police investigation and scene reconstruction by multiple agencies.
So many issues with the Buick. Made of glass. First I had no coolant line and I took it to be inspected before at, Baumen Ford and they said everything was fine with it. Turns out needed new coolant line, head gasket, timing cover, and switch. 5 new tires, rebuilt transmission, epc solenoid, transmission lines, rear pivot, left front wheel barring, formed band, and many many more. Currently with everything replaced and more that I haven’t listed/can’t state because don’t know the term. Already Has costed me 10k. And still have issues, with the APP, code P1125, P2120, P2138, & C0240. Need to inspect these car Models from 2003-2009 as they all have similar issues and nothing has been done.

In spite of multiple wheel alignments, where all of the wheels are in alignment with each other, this car still pulls sharply to the right. It is noted amongst internet discussion groups that General Motors/Buick has a common problem with a steering sensor/computer interface that causes this steering problem. I have contacted dealerships, along with Buick's California "response team" with no solution. Everybody I've spoken to so far appears to be clueless about this problem which I suspect is not a truthful response from them. The pulling has been going on for approximately 10 years, but my father (the original owner of this car) was already elderly at the time and had difficulty talking with people on the phone because of hearing loss. He let this fester. This is a serious issue because of the consistent pulling that could lead to lane drifting and cause an accident.
Low beam headlights intermittently go out. Work ok one minute, then go dark. Very dangerous. Known issue under GM recall # 14291. the federal safety agency campaign ID number 15V‑519. Problem has been confirmed by West-Herr Dodge in Rochester NY. Per info I have found this does not appear to have been permanently fixed by GM. As such the repair should be done at no charge going forward.
