WE CONTACTED TWO LOCAL GARAGES AND THEY SAY THAT THIS IS A NORMAL OCCURRENCE FOR TRAILBLAZERS, AND THAT THE HEADLIGHT SOCKET NEEDS TO BE REPLACED. I HAVE SEEN MULTIPLE COMPLAINTS ONLINE COMPLAINING ABOUT THIS SAME ISSUE. I AM ASTOUNDED THAT THERE IS NOT A SAFETY RECALL ADDRESSING THE TOTAL LOSS OF THE USE OF THE HEADLIGHTS!

MY 2005 TRAILBLAZER'S SPEEDOMETER WILL STOP WORKING WHILE I AM DRIVING. IT SEEMS AS THOUGH IT GETS TOO HOT EITHER FROM THE HEATER BEING ON OR IF I AM DRIVING A LONG DISTANCE AND IT WILL HIT A CERTAIN POINT AND THE SPEEDOMETER WILL JUST STOP WORKING. THE FIRST TIME THIS HAPPENED I WAS ON MY WAY TO CALIFORNIA FOR THANKSGIVING AND IN THE MIDDLE OF MY DRIVE I LOOKED DOWN AND I HAD TAKEN MY FOOT OFF THE GAS AND INSTEAD OF MY TRAILBLAZER SLOWING DOWN THE SPEEDOMETER KEPT RAISING. I HAD TO RELY ON MY SPEED BY MY RPM'S. I WAS ABLE TO USE THE FUSE BOX TO RESET THE SPEEDOMETER AND IT STARTED WORKING AGAIN FOR ONLY A SHORT TIME AND THEN IT STOPPED WORKING AGAIN. I HAD TO REPEAT THIS PROCESS ABOUT 5 TIMES THAT WEEKEND. SINCE THANKSGIVING WEEKEND IT HAS HAPPENED SEVERAL MORE TIMES ONLY INSTEAD OF RAISING IN SPEED THE SPEEDOMETER WILL STAY BETWEEN 0-30 MILES PER HOUR WHEN ACCORDING TO MY RPM'S I SHOULD BE GOING ABOUT 65 OR 70 MPH. I CAN TURN OFF MY TRAILBLAZER AND LET IT COOL OFF AND THEN THE SPEEDOMETER WILL START WORKING AGAIN. I HAVE FOUND SEVERAL PLACES ONLINE WHERE TRAILBLAZER OWNERS HAVE COMPLAINED ABOUT THE SAME PROBLEM. IT WILL COST SEVERAL HUNDRED DOLLARS TO FIX, BUT IF OTHER TRAILBLAZERS ARE HAVING THE SAME PROBLEM THEN THERE IS OBVIOUSLY A DEFECT WITH THE SPEEDOMETER WHICH SHOULD BECOME A NATIONAL RECALL. IT IS NOT FUN DRIVING AND THINKING YOU ARE GOING ONE SPEED WHEN YOU ARE NOT, AND I AM SURPRISED THERE HAVEN'T BEEN MULTIPLE CAR ACCIDENTS FROM THIS PROBLEM. THE DRIVER'S ELECTRICAL PANEL SHOULD NOT FAIL IN A CAR AND THAT IS A HUGE SAFETY CONCERN!!!! *TR
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
CERTAIN SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 212, 'WINDSHIELD MOUNTING.' THE WINDSHIELD URETHANE BEAD MAY NOT HAVE ADHERED TO THE BODY IN CERTAIN AREAS DURING THE CURE PROCESS.
Consequence & remedy
Consequence: IF A CRASH OCCURS, THE WINDSHIELD MAY NOT BE RETAINED, INCREASING THE RISK OF INJURY TO A VEHICLE OCCUPANT.
Remedy: DEALERS WILL REPLACE THE WINDSHIELD FREE OF CHARGE. THE RECALL BEGAN ON MARCH 10, 2005. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CHEVROLET AT 1-800-630-2438, OR GMC AT 1-866-996-9463.

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.
