THE BLOWER/FAN ON THE AIR CONDITIONER/HEATER STOPPED WORKING. IT FIRST BEGAN WITH #4 AND #5 ON THE FAN SELECTOR SWITCH NOT WORKING, BUT THEN IT STOPPED ALTOGETHER. AFTER DOING RESEARCH THIS BLOWER MOTOR PROBLEM IS VERY POPULAR AMONGST THESE VEHICLES. ALSO, THE FUEL GAUGE ON THE DASH HASN'T WORKED IN ABOUT 3 YEARS. AFTER DOING SOME RESEARCH, IT APPEARS THAT THIS IS DUE TO THE FUEL SENSOR IN THE FUEL TANK. AGAIN, THIS IS VERY COMMON OCCURRENCE WITHIN THE TRAILBLAZER COMMUNITY. I WAS GIVEN AN ESTIMATE OF $774 FOR THE BLOWER MOTOR TO BE FIXED AND $600 FOR THE FUEL GAUGE TO BE FIXED. *TR

WHILE DRIVING THE, WINDOW SWITCH BEGAN TO SMOKE SO I PHYSICALLY REMOVED THE SWITCH AND HAVE SINCE NOT HAD POWER WINDOW ACCESS ON THE PASSENGER SIDE FRONT DOOR. THE COST TO REPLACE WAS TOO GREAT AND AT THE BOTTOM OF THE PRIORITY LIST. MORE RECENTLY, MAYBE 2 MONTHS AGO, THE DRIVER SIDE SWITCH SHOWED SIGNS OF THE SAME RESULTS AFTER A SMELL OF BURNING ELECTRONICS AND HEAT TO THE TOUCH SO I SIMPLY UNPLUGGED THE SWITCH ALL TOGETHER. THE COST TO REPLACE THESE SWITCHES IS QUITE SIGNIFICANT AND HAVE NOT HAD ANY LUCK WITH CHEVROLET IN THE PAST WITH COMPLAINTS SO I FIGURED I WOULD WAIT UNTIL I HAD A LITTLE EXTRA MONEY TO REPLACE THESE SWITCHES. ON THE NEWS TODAY I HEARD THE END OF A REPORT AND ONLY CAUGHT THE WORDS GM AND WINDOW SWITCHES SO I CAME HOME AND SEARCHED AND CAME ACROSS SO ARTICLES INVOLVING 2006 MODELS. THAT IS HOW I CAME ACROSS THIS WEBSITE. I WOULD VERY MUCH HATE TO FIND OUT THAT THE COMPANY DOES NOT KNOW THE PROBLEM EXISTS FURTHER THAN 2006. AN UNRELATED PROBLEM I ENCOUNTERED WITH THE VEHICLE, WHICH WAS QUITE UNNERVING, WAS THAT THE THIRD BRAKE LIGHT ASSEMBLY CAME OFF WHILE DRIVING ON A LOCAL HIGHWAY AT @ 65 MPH APPROXIMATELY 2 YEARS AGO. THE FIXTURE BECAME UN ATTACHED FROM THE PASSENGER SIDE AND WAS "FLAPPING" OFF THE DRIVER'S SIDE. ONLY FOR A MATTER OF TIME, I'M SURE. LUCKILY OUR FAMILY WAS BEING FOLLOWED BY ANOTHER FAMILY AND THEY NOTIFIED US BY CELL PHONE AND WE WERE ABLE TO REMOVE THE FIXTURE WITHOUT INCIDENT ON THE SHOULDER. IT WOULD HAVE CAUSED SERIOUS PROBLEMS WITHOUT DOUBT HAD IT COME COMPLETELY OFF. WHEN WE NOTIFIED THE DEALERSHIP, THEY TOLD US WE WERE OUT OF OUR WARRANTY AND WERE ON OUR OWN. THANK YOU FOR TAKING THE TIME TO TRY TO MAKE OUR HIGHWAYS SAFER! *TR

06V417000 · 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.

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.
