TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE REFUELING THE VEHICLE, THE CONTACT NOTICED THAT THE EMPTY FUEL WARNING LIGHT WAS ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT STATED THAT THE FUEL GAUGE READING WAS INACCURATE AND WOULD FLUCTUATE SPORADICALLY. THE VEHICLE WAS TAKEN TO TWO DIFFERENT INDEPENDENT MECHANICS. THE MECHANIC STATED THAT THE ENTIRE INSTRUMENT PANEL WOULD NEED TO BE REPLACED. ALSO, THE CONTACT STATED THAT THE SPEEDOMETER READING WOULD ALSO FLUCTUATE INTERMITTENTLY AND PROVIDE INACCURATE READINGS. THERE WAS A CONCURRENT INVESTIGATION FOR THE FAILURE UNDER NHTSA ACTION NUMBER: DP10001 (FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP) THAT THE CONTACT BELIEVED COULD HAVE BEEN RELATED TO THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS UNAVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 58,000.

I PURCHASED THE VEHICLE IN FEBRUARY, AND THE FUEL GAUGE WORKED FINE. A FEW WEEKS LATER, AS I WAS DRIVING, THE VEHICLE STALLED.

CONFUSED, AS THE GAS GAUGE READ 1/2 A TANK REMAINING, I CALLED A FRIEND TO COME PICK ME UP. HE PUT GAS IN THE TANK, AND IT STARTED UP FIRST TRY. I MADE IT TO A FUEL STATION, AND FILLED THE TANK. THE GAUGE READ HALF ALL THE WAY TO THE STATION, AND WHEN I FILLED IT, IT READ EMPTY FOR THE FIRST 40-50 MILES. THEN, THE NEEDLE FLOATED THE RANGE OF THE GAUGE. IT HAS BEEN DOING THIS EVER SINCE. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE WOULD FLUCTUATE BETWEEN FUEL LEVELS, EVEN WITH A FULL TANK OF GAS. THE FAILURE WOULD CAUSE THE VEHICLE TO STALL SPORADICALLY WITHOUT WARNING. THE DEALER ADVISED THE CONTACT THAT BECAUSE THE VEHICLE WAS NO LONGER UNDER WARRANTY, THEY WERE UNABLE TO ASSIST. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHO DIAGNOSED A FAULTY FUEL SENSOR, WHICH WAS REPLACED. IN ADDITION, THE DEALER REPLACED THE FLOAT AND FUEL TANK YET THE FAILURE WAS NOT CORRECTED AND PERSISTED INTERMITTENTLY. THE CURRENT MILEAGE WAS 84,562 AND THE FAILURE MILEAGE WAS 78,000.

THE GAS GAUGE IN MY 2005 CHEVY TRAILBLAZER HAS STOPPED WORKING. IT BEGAN TO SHOW EMPTY AFTER FILLING MY TANK BUT THEN REGISTERING FULL ABOUT 50 MILES AFTER DRIVING. NOW IT ALWAYS SHOWS EMPTY AND I HAVE TO RECORD MY MILEAGE TO KEEP TRACK OF MY GAS. I AM ALWAYS CONCERNED I MAY RUN OUT OF GAS IF I MISCALCULATE MY REMAINING GAS. I CAN'T TAKE MY 2005 TRAILBLAZER ON VACATION SINCE I HAVE NO WAY OF KNOWING HOW MUCH GAS IS IN MY VEHICLE. MY WIFE RAN OUT OF GAS ON THE HIGHWAY AND WAS ALMOST IN AN ACCIDENT. THE DEALER WANTED ALMOST $800 DOLLARS AND TWO DAYS TO FIX THE GAS GAUGE. I CANNOT AFFORD THE REPAIRS SO I AM FORCED TO HOPE I WILL BE SAFE IN MY VEHICLE. *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.
