MY 2005 GMC ENVOY GAS GAUGE BEGAN TO BECOME ERRATIC IN NOVEMBER OF 09. AT THAT TIME IT WOULD WORK SOME TIMES AND NOT OTHERS. AFTER A FEW WEEKS IT STOPPED WORKING IN ANY MANNER AND CONSTANTLY FLUCTUATES UP AND DOWN, CAUSING THE LOW FUEL INDICATOR TO GO ON AND OFF. THIS OCCURS EVEN WHEN THE VEHICLE HAS JUST BEEN FILLED WITH GAS AND THE GAS CAP TIGHTENED. THE ONLY WAY TO MONITOR GAS AT THIS TIME IS THROUGH TRACKING MILEAGE. VEHICLE WILL RANDOMLY STALL WHEN IDLE. THE STALLING IS NOTED TO BE OCCURRING MORE FREQUENTLY THE LONGER THIS GOES UNREPAIRED. STALLING AT LIGHTS, IN PARKING LOTS AND WHILE BACKING UP PUTS US AT RISK OF BEING HIT BY ANOTHER VEHICLE. ALSO THE INABILITY TO ACCURATELY MONITOR THE AMOUNT OF GAS IN THE VEHICLE PUTS MYSELF AND MY FAMILY AT RISK OF BEING STRANDED WHILE TRAVELING. THE ONLY OTHER PERSON I KNOW WITH THIS SAME MAKE AND MODEL HAS THE SAME PROBLEM. CORRECTION IS REPLACEMENT OF THE PART WHICH IS BETWEEN $600 AND $800. *TW

THE HIGH BEAMS IMMEDIATELY ACTIVATE WHEN THE HEADLIGHTS SHUT OFF WHICH DISTRACTS DRIVERS. THE FAILURE MILEAGE WAS 28000 AND THE CURRENT MILEAGE WAS 58000.

NEVER HAD FUEL GAUGE PROBLEMS BEFORE, FILLED MY TANK, DROVE AWAY FROM GAS STATION AND WITHIN ONE MILE, THE FUEL BELL WENT OFF AND THE WARNING LIGHT TURNED ON. WENT BACK TO GAS STATION THINKING I HAD BEEN RIPPED OFF, BUT OWNER SHOWED ME ON GAS PUMP THAT IT HAD PUMPED $60 WORTH OF GAS. NOW THE FUEL GAUGE DOESN'T WORK AT ALL, THE WARNING LIGHT IS ALWAYS ON. I'VE BEEN GIVEN QUOTES TO FIX IT RANGING FROM $400 TO $600. WITH ALL THESE PROBLEMS, GM SHOULD ISSUE A RECALL AND FIX FOR EVERYONE FREE. *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.
