I WAS DRIVING DOWN THE HIGHWAY AFTER DARK AND MY LOW BEAMS COMPLETELY WENT OUT. I COULD ONLY GET MY HIGH BEAMS TO WORK. CURRENTLY ONLY ONE LOW BEAM IS WORKING AND THE OTHER WILL NOT WORK EVEN AFTER CHANGING THE BULB OR THE FUSE. I BELIEVE THIS IS A HUGE SAFETY CONCERN ESPECIALLY HAVING A YOUNG CHILD. IT WAS VERY SCARY GOING DOWN THE ROAD AT NIGHT AND HAVE YOUR LIGHTS COMPLETELY JUST GO OUT. I HAVE NOTICED THAT THERE ARE ISSUES WITH 06-07 ENVOYS BUT I WANTED GM TO BE MADE AWARE THAT 2005 MODELS HAVE BEEN AFFECTED AS WELL.

THERE ARE MANY ISSUES WITH THIS THAT I'VE FOUND WHILE SEARCHING THE WEB. IT IS UNNERVING AND DANGEROUS TO NOT KNOW THE SPEED YOU ARE TRAVELING.

2RQ17002 · 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.
