RECENTLY, THE GAS GAUGE ON MY 2005 CHEVY TRAILBLAZER QUIT WORKING. I FILLED UP, AND THE GAUGE SET AT EMPTY UNTIL I HAD DRIVE 10-15 MILES. UNTIL THEN, THE EMPTY LIGHT WOULD STAY ON AND THE "MILES LEFT" SHOWS NONE WHICH RENDERS THAT ALERNATE SOLUTION UNUSABLE. THE ONLY THING THAT WORKS CLOSE ENOUGH TO LET ME DETERMINE IF I NEED TO FILL UP AGAIN IS THE "TRIP A" FEATURE. I CAN GUESS HOW MANY MILES I NORMALLY GO BEFORE A FILL UP.. BUT WHO'S TO SAY THAT IS WORKING RIGHT EITHER? THE IMPROPER FUNCTIONING OF THIS ELEMENT OF MY VEHICLE IS NOT ONLY A PAIN IN THE BACKSIDE, BUT ALSO COULD BE DETRIMENTAL TO THE SAFETY OF MYSELF AND MY CHILD IF THE CAR WERE TO RUN OUT OF GAS WHILE TRAVELING DOWN THE HIGHWAY. I HAVE FOUND FORUMS RECENTLY WHEREIN MANY CUSTOMERS OF GM ARE HAVING THE SAME DIFFICULTY WITH THE SAME MAKE AND MODEL. WE ARE ALL FRUSTRATED TO SAY THE LEAST. I HAVE HEARD THERE WERE RECALLS FOR THIS ISSUE PRIOR TO 2004 - SEEMS GM DIDN'T GET IT RIGHT AFTER THAT TIME. HOW ABOUT A RECALL NOW? *TR

THE FUEL GAUGE DISPLAYED INACCURATE READINGS AND THE DRIVER WAS UNABLE TO DETERMINE THE VEHICLE'S FUEL TANK CAPACITY. ASSISTANCE WAS CALLED TO THE SCENE AND THE VEHICLE WAS TAKEN TO THE AUTHORIZED DEALER FOR INSPECTION. THE TECHNICIAN STATED THAT THE FAILURE WAS RELATED TO THE FUEL SENSOR. THE VEHICLE WAS REPAIRED. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON A SEPARATE OCCASION FOR THE SAME FAILURE AND A PART WAS ORDERED FOR THE FAILED COMPONENT. THE VEHICLE CANNOT BE REPAIRED AGAIN UNTIL THE PART IS AVAILABLE. THE FAILURE MILEAGE WAS 36,000.

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.
