For several years the low beam headlights would go off and on intermittently. Now, they are mostly off which means I cannot drive my vehicle at night anymore unless I want to blind people or get stopped. I have changed headlamps, relays and fuses to no avail. Now, I see that many others with the same make and model SUV have been having the same issue but no recalls have been issued for this year model. This is a major safety issue when we have to drive with the high beams on and when the lights go off unexpectedly. If you will issue a recall for one year model having a particular issue, why would you not do the same with all year models having the same issue? Come on chevrolet and the federal safety agency, let's get this problem solved to save some lives. It is very scary to be driving and have your headlights go out and a major pain to have to be sure you are home by dark or not be able to go out after dark because your headlamps are or may stop working.

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.

I have my bright lights,but I dont have my regular headlights,somtimes they come on then they go out,ive changed the module under the hood & it still does the same thing,it happens when im going down the road
While driving low beam headlights go out. High beams will work. Sometimes low beams will come back on during same trip. Replaced hdm module per issues with 2006 but headlights still go out while driving.
Both headlamps went out same night. High beams work. Checked fuses all are fine. Very dangerous as high beams are not meant to be used in this fashion. I see there are recalls on same model other years.
