WHILE DRIVING THE CAR IT CUTS OFF WHILE IN THE DRIVE GEAR. THIS HAPPENED 4 TIMES, TWICE WHILE DRIVING ON THE BELTWAY ALL WITHIN A 3 WEEK PERIOD. I HAVE E TO PUT THE CAR IN PARK AND WAIT ABOUT 2 MINUTES THEN START IT UP AGAIN. I WAS SCARED TO DRIVE THE CAR AFTER THE SECOND TIME STOPPING ON THE BELTWAY, SO I HAD THE CAR TOWED TO THE SHOP. THIS WAS VERY DANGEROUS AND STRESSFUL NOT KNOWING WHEN THE CAR WOULD STOP AT ANY GIVEN TIME. THE DEALER HAD TO REPLACE THE COMPUTER IN THE CAR AT A COST ON $690.00, FROM ME. I THINK THIS IS UNACCEPTABLE AND THAT I SHOULD BE COMPENSATED FOR THIS AMOUNT. IF THIS MODEL NEEDS TO BE RECALLED THEN IT SHOULD BE BEFORE SOMEONE GETS HURT OR KILLED. I WILL BE WRITING THE BETTER BUSINESS BUREAU ALSO TO FILE A COMPLAINT. I GET MY MAINTENANCE ON THIS VEHICLE ON A REGULAR BASIS. I'M GLAD THAT I WAS NOT SERIOUSLY HURT WHEN THIS CAR STOPPED ON THE BELTWAY. MY CAR WAS REPAIRED ON JULY 16,2016, AT ANDERSON OF HUNT VALLEY, 10125 YORK ROAD, COCKEYSVILLE MD 21030. PHONE # 410-403-1300. THEY DID A GREAT JOB IN REPLACING THE COMPUTER, NOW I NEED TO BE COMPENSATED FOR MY $690.00. THANKING YOU IN ADVANCE FOR YOUR TIME AND COOPERATION.SINCERELY [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

Official recalls

15V519000 · Exterior Lighting:headlights

Aug 14, 2015

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.

Consequence & remedy

Consequence: 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.

RQ17002 · Loss Of Headlights

Opened Apr 24, 2017 · Closed Mar 29, 2021

Status: closed (inferred from source dates) · Exterior Lighting: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 NHTSA 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 NHTSA.gov under the identification numbers in the attached document.
