THE LIGHTING, BOTH INTERIOR AND EXTERIOR, FLICKERS THIS CAUSES DISORIENTATION AND INHIBITS MY ABILITY TO DRIVE SAFELY. IT HAS ALSO CAUSED ME TO BE PULLED OVER BY POLICE BECAUSE HE THOUGHT THERE WAS SOMETHING WRONG IN THE VEHICLE. I DO NOT EVEN LIKE DRIVING AT NIGHT ANYMORE BECAUSE I'M AFRAID THEY WILL GO OUT COMPLETELY. *TR

MY SPEEDOMETER DOES NOT WORK AT ALL. THE HEATER AND A/C DON'T WORK. MY FUEL GAUGE DOES NOT WORK. THE INTERIOR LIGHTS INSIDE MY CAR DO NOT WORK, THE RIGHT FRONT PASSENGER WINDOW DOES NOT WORK. BASICALLY MY ENTIRE DASHBOARD DOES NOT WORK. WHAT DID CHEVY DO ABOUT IT?? SENT ME A LETTER STATING THEY ARE WILLING TO PAY HALF OF THE COST TO REPAIR THE FUEL GAGE BUT IT WOULD HAVE TO BE FIXED AT A CHEVY DEALERSHIP. I COULD GET THE SAME THING FIXED AT MY MECHANIC AND PAY THE FULL AMOUNT AND IT WOULD STILL COST ME LESS THAN HAVING THE DEALERSHIP FIX IT AND CHEVY PAYING HALF THE COSTS. DON'T THINK I WILL BE BUYING ANOTHER CHEVY ANYTIME SOON. *TR

THE CONTACT STATE THAT WHILE IN A PARKING LOT, THE SPEEDOMETER ERRONEOUSLY DISPLAYED THAT THE CONTACT WAS TRAVELING 30 MPH WHEN THE ACCELERATOR WAS NOT BEING DEPRESSED.

SPEEDOMETER JUMPS ALL OVER THE PLACE. EVERYDAY NOW IT WILL JUMP FORWARD. WHEN I STOP AT A STOP LIGHT IT WILL STICK AT SOME MPH NOT GOING TO ZERO.

Official recalls
206V417000 · Air Bags:frontal
Oct 31, 2006
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.

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.

2RQ17002 · 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.
