TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE WAS NOT WORKING PROPERLY ON THE INSTRUMENT PANEL. HE TOOK THE VEHICLE TO THE DEALER AND THEY STATED THAT THE FUEL SENSOR LOCATED INSIDE THE GAS TANK WAS FAULTY AND NEEDED TO BE REPLACED. THROUGH ONLINE RESEARCH, THE CONTACT DISCOVERED THAT FUEL SENSOR FAILURES FOR THE TRAILBLAZERS WERE VERY COMMON. THE VEHICLE HAS NOT BEEN REPAIRED DUE TO THE TREATMENT THE CONTACT RECEIVED AT THE DEALER. HE FEELS THAT THE INFORMATION ABOUT THE FUEL SENSOR SHOULD HAVE BEEN SHARED BY THE DEALER, RATHER THAN BEING DISCOVERED ON THE INTERNET. HE ALSO FEELS THAT THE VEHICLE IS UNSAFE BECAUSE THERE COULD BE NO FUEL IN THE TANK UNBEKNOWNST TO THE CONTACT. THE CURRENT MILEAGE WAS 57,985 AND FAILURE MILEAGE WAS 52,000.

I HAVE HAD THE PROBLEM THAT SO MANY OTHERS HAVE HAD WITH THE FUEL GAUGE. AFTER FILLING MY TANK, WHEN I STARTED MY 2005 TRAILBLAZER THE GAUGE READ EMPTY AND THE LOW FUEL LIGHT WAS ON. EVENTUALLY, THE NEEDLE DID MOVE TO WHERE I THINK IT WAS MAYBE AN ACCURATE READING. HOW ABOUT THE LUNGING FORWARD THE VEHICLE DOES WHEN PULLING INTO A PARKING SPOT WHICH CAUSES A DANGER TO ANYONE POSSIBLE WALKING IN THE AREA. ALSO, FOR NO APPARENT REASON, MY 4 WHEEL DRIVE JUST STOPPED WORKING. I HAVE OWNED NOTHING BUT CHEVROLET'S FOR THE LAST 30 YEARS AND NEVER HAVE I BEEN DISAPPOINTED WITH ANY VEHICLE AS I AM WITH THIS ONE. OH YEAH AND I AM ALSO LEAKING TRANSMISSION FLUID. MY 2005 TRAILBLAZER HAS APPROXIMATELY 80,000 MILES ON IT WHICH I DON'T FEEL WARRANTS THESE MAJOR ISSUES. *TR

I FILL THE VEHICLE, AND IT ONLY SHOWS A HALF TANK. THEN IT WILL GO TO EMPTY WITH THE WARNING LIGHT COMING ON. AS SOMEONE WHO TRAVELS A LOT, AND FOR LONG DISTANCES, THIS IS A HORRIBLE DEFECT.

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.
