When owners reported it
Related recalls (3)
Exterior lighting:headlights
Model years: 2006, 2007
Problem: 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.
Fix: 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.
Exterior lighting:turn signal
Model years: 2003, 2004
Problem: On certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only.
Risk: The driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash.
Fix: Dealers will replace the suspect flasher modules with a new flasher module designed with sealed relays and more durable contact material inside of the relays free of charge. The recall began on august 4, 2005. Isuzu began mailing owner letters on august 4, 2005. Owners may contact chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, isuzu at 1-800-255-6727, buick at 1-866-608-8080, and oldsmobile at 1-800-630-6537.
Exterior lighting:brake lights
Model years: 2002, 2003, 2004
Problem: On certain sport utility vehicles, vibration and heat may cause the tail lamp/stop lamp bulb to loosen in its socket. If this occurs, the bulb may flicker and eventually become inoperative.
Risk: An inoperative brake lamp will not convey the driver's intention of stopping to drivers in following vehicles, and an inoperative rear turn signal lamp will not convey the driver's intention to turn to drivers in following vehicles. Both of these failures can increase the risk of a crash.
Fix: Dealers will inspect the tail lamp/stop lamp assemblies, and if necessary, replace them. The recall began on november 22, 2004. Owners should contact chevrolet at 1-800-630-2438, oldsmobile at 1-800-630-6537, buick at 1-866-608-8080, or gmc at 1-866-996-9463.

Unit used as a rental from Avis. Night time driving will cause on-coming traffic to flash high beams while my lights are in low beam mode. This is a daily problem with a multitude of on-coming drivers as the LED headlights are perceived to be extra bright / blinding.

The headlamps have quit working when driving at night but will come back on later. This has happened several times.
