LOWBEAM LIGHTS TURN OFF AT SAME TIME RANDOMLY WHILE DRIVING. THIS IS VERY HAZARDOUS AND YOUR "SAFETY COVERAGE" ONLY COVERS HDM MODULES TO BE REPLACED WHICH IS A TEMPORARY FIX (LASTS USUALLY 2 MONTHS) THIS IS WIDELY KNOWN ISSUE ON THESE VEHICLES DATING BACK TO 2005 AND IF I GET IN A SERIOUS WRECK DUE TO YOUR NEGLIGENCE I WILL BE TAKING ACTION. I'M SICKENED YOU WOULD COVER THE COSTS OF A PERMANENT FIX WHEN YOUR CUSTOMERS ARE SUCH AT A HIGH RISK OF FATALITIES WHILE DRIVING. (THIS ISSUE HAS BEEN REOCCURRING FOR THE LAST YEAR AND HAVE COME CLOSE TO MANY ACCIDENTS)

UPON STARTING OF THE CAR UNDER NORMAL CONDITIONS, NOTICED A SLIGHT BURNT ELECTRICAL SMELL, AFTER INSPECTION OF THE ENGINE COMPARTMENT, I DID NOT NOTICE ANY SMOKE OR OBVIOUS SIGNS, AND THE SMELL WENT AWAY, THIS HAPPENED TWICE WHILE OUT SHOPPING AT VARIOUS PLACES. ON THE FINAL LEG OF THE TRIP ON THE WAY HOME, I NOTICED THE SMELL BECOMING MORE APPARENT, AND THE SMELL WAS NOTICEABLE AT TRAFFIC LIGHT STOPS. ONCE HOME, I ONCE AGAIN INSPECTED THE COMPARTMENT, AND NOTICED A MELTED SPOT ON THE TOP OF THE FUSE BOX, AFTER OPENING, THE LOW BEAM RELAY WAS BURNT BEYOND RECOGNITION AND FUSED TO THE WIPER RELAY. IN ORDER TO USE HEADLIGHTS, I NOW HAVE TO REPLACE THE WHOLE FUSE BOX DUE TO THE BURNT SPOT IN THE COVER AND THE FUSE BOX. SEE ATTACHED PICTURES. I COULD NOT ATTACH THE PICTURE OF PLASTIC DUST WHICH IS WHAT IS LEFT OF THE RELAY, DUE TO SIZE LIMITATIONS.

LOW BEAM HEADLIGHTS GO OFF, AND SOMETIMES ON AGAIN BY THEMSELVES. THIS HAPPENS AFTER DARK, WHILE DRIVING. IT ALSO HAPPENS IN EARLY EVENING WHEN HEADLIGHTS SHOULD BE ON . THIS HAS BEEN HAPPENING FOR A FEW WEEKS . LOOKING ON THE INTERNET, I SEE THERE IS A RECALL FOR THIS IN 2007 MODELS.

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.
