FUEL GAUGE PEGGED OUT PAST FULL THEN RETURNED TO EMPTY. IT HAS NOT BEEN CORRECT SINCE. MECHANICS I HAVE TALKED TO SAID THIS IS AN ONGOING PROBLEM WITH THE TRAILBLAZERS. I THINK THERE SHOULD BE A RECALL ISSUED FOR THE PROBLEM. I NOTICED ON THE NHTSA WEBSITE THAT THERE HAVE BEEN OVER 600 COMPLAINTS FILED. THIS COULD BE A REAL PROBLEM AND COULD POSSIBLY BE A REAL SAFETY HAZARD TO FAMILIES. SUPPOSE YOU RUN OUT OF FUEL GOING DOWN THE INTERSTATE AT 70 MPH AND YOU RUN OUT OF FUEL AND CAN'T GET TO THE EMERGENCY LANE, SOMEONE COULD POSSIBLY REAR-END YOU BECAUSE YOU CAN'T GET OVER. I THINK THIS SHOULD BE FIXED AT GM'S COST. *TR

I WAS DRIVING DURING SUMMER TIME AND MY FUEL GAGE WENT FROM FULL TO EMPTY FOR NO REASON. I HAD JUST FILLED UP, SO I KNEW THERE WAS GAS IN THE TANK. IT HAS SINCE GIVEN ME RANDOM READINGS. IF I LET THE GAS LEVEL FALL BELOW 3/4 OF A TANK. IT WILL GO TO EMPTY EVEN IF I FILLED THE TANK. IT DOES WORK RANDOMLY SOMETIMES. *TR

DRIVER SIDE MASTER POWER WINDOW SWITCH DOES NOT WORK THE DRIVER SIDE WINDOW AT ALL! OUT OF THE BLUE THIS STOPPED WORKING. FURTHER RESEARCH SHOWS THAT THE 2006-2007 MODELS WERE RECALLED NOT THE 2005! REALLY, THIS CAR IS "CURRENTLY REGISTERED IN A COLD WEATHER STATE WHICH USES SALT TO CLEAR THE ROADS" (DIRECT QUOTE FROM GENERAL MOTORS AND ISUZU RECALL 258,000 SUVS, THE ASSOCIATED PRESS, AUGUST 19, 2012) SINCE 12/2005 WHICH IS WHEN THE VEHICLE WAS PURCHASED. JUST BECAUSE MY VEHICLE DID NOT HAVE A FIRE "YET" BUT I HAVE THE "EXACT" PROBLEM WHICH AROSE BEFORE THESE VEHICLES DID CATCH FIRE, MINE IS NOT RECALLED? NOT ONLY WAS THE TRANSMISSION RECALLED IN 2008, I HAD A PROBLEM WITH THE "BLOWER MOTOR" NOT WORKING WHEN YOU TURN ON THE HEAT. YOU COULD ONLY TURN ON THE HEAT TO NO. 4. THE TRUCK WAS TAKEN FOR SERVICE ON 1/10/06, 1/30/06, 2/7/06 AND 2/17/06 WHICH WAS NOT EVEN 2 MO. AFTER PURCHASING SAID VEHICLE BEFORE THE PROBLEM WAS CORRECTED. IN 11/06 THE "FUEL PUMP MODULE" WAS REPLACED AND COVERED "ONLY" BECAUSE I HAD THE EXTENDED WARRANTY AND I HAD TO PAY THE $100.00 DEDUCTIBLE, BECAUSE I HAD GAS BUT IT WAS NOT REGISTERING. AGAIN, I CONTINUE TO HAVE THIS PROBLEM. WHEN CALLING GM ON 7/24/13 ABOUT THE WINDOW SWITCH RECALL, I NOW FIND OUT THAT THERE IS A "SPECIAL COVERAGE" FOR THE "FUEL LEVEL SENSOR". THIS IS COVERED UNTIL 7/24/14, PER GM (866-694-6546), UNLESS YOU HAVE MORE THAN 120,000 SOMETHING MILES. WAS NOT SURE OF THE MILEAGE EXACTLY SINCE MINE IS BELOW THAT FIGURE. THE WINDOW SWITCH IS A SERIOUS MALFUNCTION THAT NEEDS TO BE COVERED IN "ALL YEARS" OF THIS VEHICLE. WHILE SITTING AT A RED LIGHT WITH YOUR FOOT ON THE BRAKE, THE VEHICLE WILL JUST REV UP AND WANT TO TAKE OFF. I GUESS THIS ISN'T A "BIG DEAL" EITHER. YOU CAN'T EVEN LISTEN TO THE RADIO TO DISTRACT YOU WITH ALL THESE PROBLEMS GOING ON BECAUSE THE RADIO ONLY COMES OUT OF "ONE" SPEAKER! GO FIGURE, IT IS GM! *TR

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.
