AND THE LAST THING IS THAT THE FUEL GAUGE FLUCTUATES DRAMATICALLY AND YOU CAN NEVER TELL HOW MUCH FUEL YOU REALLY HAVE... DRIVE 10 MILES AT QUARTER OF A TANK AND IT EITHER STAYS CLOSE TO THE SAME SPOT OR DROPS AND THE LIGHT COMES ON FOR LOW FUEL. *TR

THE SPEEDOMETER DOES NOT RESET ITSELF WHEN THE VEHICLE SLOWS OR STOPS. INSTEAD, IT RESUMES FROM A HIGHER SPEED. FOR EXAMPLE, IF YOU ARE TRAVELING AT 45MPH AND STOP AT A STOPLIGHT THE SPEEDOMETER MAY DROP TO 40MPH UPON STOPPING. THEN WHEN YOU RESUME TRAVELING IT STARTS FROM 40 INSTEAD OF 0 SO THE SPEEDOMETER SHOWS YOU ARE TRAVELI…

THE SPEEDOMETER DOES NOT RESET ITSELF WHEN THE VEHICLE SLOWS OR STOPS. INSTEAD, IT RESUMES FROM A HIGHER SPEED. FOR EXAMPLE, IF YOU ARE TRAVELING AT 45MPH AND STOP AT A STOPLIGHT THE SPEEDOMETER MAY DROP TO 40MPH UPON STOPPING. THEN WHEN YOU RESUME TRAVELING IT STARTS FROM 40 INSTEAD OF 0 SO THE SPEEDOMETER SHOWS YOU ARE TRAVELING 60 WHEN YOU ARE GOING 20, 70 WHEN YOU ARE GOING 30 ETC. WHEN YOU STOP AGAIN IT WILL COME TO REST AT AN EVEN HIGHER SPEED, UNTIL EVENTUALLY THE NEEDLE SHOWS OVER 120 MPH WHEN THE VEHICLE IS SITTING STILL! I HAVE DONE SOME INVESTIGATION ON LINE AND THIS APPEARS TO BE A FAIRLY COMMON COMPLAINT FROM FELLOW OWNERS. GENERAL MOTORS APPARENTLY DOPES NOT CONSIDER THIS A SAFETY ISSUE AND AS SUCH WILL NOT PAY FOR THE REPAIR WHICH IS $500 OR MORE. I'M NOT SURE HOW NOT KNOWING YOU RATE OF TRAVEL IS NOT A SAFETY CONCERN FOR THEM, BUT IT CERTAINLY IS TO ME. *TR

DURING ROUTINE DRIVING AROUND KEENE NH THE SPEEDOMETER STOPPED WORKING. NOTHING HAS BEEN DONE YET. *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.
