My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again.

My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again. The 2nd complaint is the radio volume would 'slip' as if there were a loose wire to the speakers, and loss of sound became more frequent and for longer periods of time, eventually all sound stopped, it has not been fixed, as of yet. 3rd complaint, a brand new battery, in under a year of use, went completely dead, without any visible explanation. When an attempt to jump start the vehicle the cables from another cars battery were touched at my cars battery, it sparked, indicating to the person performing the task, there is a 'short' somewhere in the wiring system. I drive this vehicle less than 3000 miles per year, and use it sporadically with my second vehicle to keep the batteries active. I cannot explain why these issues are occurring but thought it important to mention them to other possible victims with the same issues.

THE LOW BEAM HEADLIGHTS KEEP GOING OUT. ALL OTHER LIGHTS STAY ON AND THE HIGH BEAM LIGHTS WORK. ONLY THE LOW BEAM HEADLIGHTS ARE AFFECTED. THIS HAS HAPPENED WHILE IN MOTION AND FROM A STOPPED POSITION WHEN FIRST STARTING THE CAR AND PUTTING IT IN DRIVE. I HAVE RESEARCHED IT ON SEVERAL GROUP WE SIGHTS AND FOUND THAT THE PROBLEM IS THE HEADLIGHT DIMMER MODULE (HDM). I HAVE REPLACED THIS TWO TIMES OVER THE LAST TWO YEARS WHICH ALWAYS FIXES IT FOR ABOUT A YEAR THEN IT STARTS FAILING AGAIN. THIS IS A VERY DANGEROUS SITUATION BECAUSE IT HAPPENS AFTER DARK. I CAN PULL OVER AND STOP, OPEN THE HOOD AND TAKE OFF THE FUSE BOX COVER AND REMOVE THE HDM AND PUT IT BACK IN THE SOCKET. SOMETIMES THIS WORKS AND SOMETIMES NOT. IT IS A DANGEROUS SITUATION. THERE HAVE BEEN RECALLS ON EARLIER TRAILBLAZERS BUT NOT THIS YEAR. IT SHOULD BE INCLUDED.

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.
