SHE PULLED THE VEHICLE OVER AND NOTICED THAT THE PLASTIC COVERING DETACHED ON THE BRAKE LIGHT, WHICH WAS LOCATED ON THE REAR LIFTGATE. THE CONTACT WAS ABLE TO SAFELY PLACE THE PIECE BACK ON, BUT THE WIRES WERE EXPOSED. THE PIECE IS NOT SAFELY IN PLACE BECAUSE IT IS BEING HELD TOGETHER BY DUCT TAPE. THE VEHICLE HAS NOT BEEN REPAIRED. THE DEALER STATED THAT THE FAILURE WOULD NOT BE COVERED UNDER WARRANTY. THE MANUFACTURER WOULD NOT PROVIDE COMPENSATION BECAUSE THE FAILURE WAS NOT COVERED UNDER WARRANTY. THE FAILURE MILEAGE WAS 31,000 AND CURRENT MILEAGE WAS 33,500.

REPAIRS WERE MADE UNDER WARRANTY; HOWEVER, THE LAST FAILURE WAS THE CONTACT'S LIABILITY. ON A SEPARATE OCCASION, SHE HEARD A LOUD NOISE COMING FROM THE REAR OF THE VEHICLE. THE MANUFACTURER STATED THAT THERE WAS A PINCHED WIRE ISSUE WITH THAT PARTICULAR YEAR, MAKE, AND MODEL VEHICLE THAT COULD AFFECT OTHER ELECTRICAL COMPONENTS. THE DEALER MADE REPAIRS, BUT THE FAILURE RECURRED WITHIN 48 HOURS. THE DEALER FOUND WIRING IN A DIFFERENT AREA THAT FAILED AND SUBSEQUENTLY CAUSED THE FAILURE OF THE FRONT PASSENGER SEAT. IN ADDITION, THE EXTERIOR LIGHTS FLICKERED INTERMITTENTLY, BUT THE MECHANIC STATED THAT THE WIRING WOULD NOT CAUSE THAT PARTICULAR FAILURE. THE VIN WAS PROVIDED, BUT WAS NOT ACCEPTED BY THE SYSTEM. THE CURRENT AND FAILURE MILEAGES WERE LESS THAN 43,000.

THE SPEEDOMETER STICKS AT VARIOUS SPEEDS. SOMETIMES IT SHOWS *BELOW* ZERO WHEN I'M MOVING. LAST NIGHT, I WAS TRAVELING AT APPROX. 65-70MPH, I ASSUME, BUT THE SPEEDOMETER WAS STUCK AT 30. WHEN DECELERATING, THE SPEEDOMETER WILL STICK AT CERTAIN SPEEDS, AND THEN JERK DOWN SUDDENLY. MY TRAILBLAZER ONLY HAS ABOUT 53,000 MILES ON IT. I HAVE SEEN REPORTS OF THIS ISSUE BEGINNING AT 30K, BUT MOST KICK IN AT AROUND 50K. I AM CALLING THE SHOP TODAY. FROM WHAT I'VE READ, IT'S RELATED TO A FAULTY STEPPER MOTOR. IF I AM ABLE TO UPDATE THIS REPORT, I WILL. HOWEVER, I THINK THIS IS VERY UNSAFE AND AM NOT GOING TO WAIT TO REPORT IT UNTIL AFTER THE REPAIR; I'VE SEEN AT LEAST 40 (I STOPPED COUNTING) OTHER COMPLAINTS ABOUT A MALFUNCTIONING SPEEDOMETER IN 05 TRAILBLAZERS ON ABOUTAUTOMOBILE.COM (I ALSO HAVE ISSUES WITH DIMMING LIGHTS AND HEADLIGHTS FLASHING AT NIGHT). *TR

MASSIVE ELECTRICAL PROBLEMS WITH CHEVY TRAILBLAZER 1. WHILE GOING 10 MILES AN HOUR, THE SPEEDOMETER JUMPS TO 120MPH THEN TO 50MPH THEN TO 120MPH AGAIN. 2. WHEN I FILL UP WITH GAS, THE GAS GAUGE STATES THAT THE TANK IS STILL EMPTY THEN MOVES TO FULL THEN TO A 1/4 THEN TO FULL THEN TO HALF ETC... 3. WHILE DRIVING AT NIGHT, MY HEADLIGHTS GO HIGHBEAM TO LOW BEAM AS IF I AM MANUALLY FLASHING MY LIGHTS AT OTHER CARS. I HAVE READ ON THE INTERNET WHERE THIS IS HAPPENING TO MANY MANY PEOPLE WITH THIS SAME MODEL OF CHEVROLET SUV AND THAT GM REFUSES TO DO ANYTHING ABOUT THIS. -I CALLED GM AND ADVISED THEM OF THE ENTIRE ISSUE. THEY ADVISED ME TO GO TO A DEALERSHIP AND HAVE THEM RUN A DIAGNOSTIC AS THIS WAS NEEDED BEFORE THEY COULD HELP ME. -I WENT TO THE DEALER AND PAID $115 FOR THE DIAGNOSTIC, NEEDLESS TO SAY THE REPAIRS THAT THE DEALER FOUND RANGER OVER $3000.00 DOLLARS. -I THEN CALLED GM BACK AND THEY TOOK THE INFORMATION THAT THE DEALER GAVE ME (DONNA AT 1-866-790-5700 X21153) -I JUST GOT A CALL BACK FROM GM STATING THAT BECAUSE OF THE MILEAGE ON THE SUV THAT THEY WERE NOT GOING TO DO ANYTHING (THEY KNEW ABOUT THE MILEAGE BEFORE THEY SENT ME TO THE DEALERSHIP!). SO I WASTED $115 DOLLARS FOR SOMETHING THAT WAS NOT NEEDED BY GM, AND THE FACT THAT THEY KNEW ABOUT THE MILEAGE TO START OFF WITH IS A WAY TO LET THE DEALER MAKE SOME MONEY OFF THE CONSUMER. *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.
