NOT SURE WHAT TO FILE THIS UNDER, SO I PUT IT UNDER UNKNOWN AND OTHER. ABOUT 4 MONTHS AGO MY SERVICE ENGINE SOON LIGHT CAME ON. IT STAYED ON FOR A FEW DAYS THEN WENT OFF, A FEW DAYS LATER IT WAS BACK ON, THEN A FEW DAYS LATER WENT OFF, THEN IT CAME ON FOR A LONGER PERIOD OF TIME AND DO THE SAME THING, EVENTUALLY IT STAYED ON. TOOK IT TO THE CHEVY DEALERSHIP WHERE I BOUGHT IT AND THEY SAID THE GAS TANK HAD A CRACK IN IT AND NEEDED TO BE REPLACED. SAID IT WAS PROBABLY FROM THE GAS NOZZLE HITTING THE TANK WHEN FILLING IT UP. DON'T SEE HOW THAT IS POSSIBLE, WHEN IT IS ONLY ME OR MY HUSBAND FILLING IT UP & HOW HARD WOULD YOU HAVE TO HIT IT FOR IT TO CRACK? HAD IT REPLACED THE NEXT MONTH. NOW THE SERVICE ENGINE SOON LIGHT IS DOING THE SAME THING. HAVEN'T TAKEN IT BACK IN YET. *TR

MY WIFE'S 2004 TRAILBLAZER EXT SERVICE ENGINE SOON LIGHT CAME ON IN LATE SEPTEMBER 2009. SHE HAD BEEN COMPLAINING OF A GASOLINE SMELL AFTER FILLING THE VEHICLE. I HAD THE OBDII CODE READ AND IT WAS CODE 0440 EVAPORATIVE FUEL SYSTEM - SMALL LEAK. I WAS TOLD TO REPLACE THE GAS CAP, AND IT DID NOT REMEDY THE PROBLEM. I THEN FOUND OUT THAT THE 2002-2004 TRAILBLAZER EXT HAD A KNOWN PROBLEM WITH THE GAS TANK FILLER NECKS DEVELOPING CRACKS AND CAUSING THE SES LIGHT TO COME ON AND GAS TO LEAK WHEN THE TANK IS FILLED OR NEAR FULL. I CONTACTED CHEVROLET, WHO STATED THAT OUT TRAILBLAZER IS NOT IN THE VIN RANGE OF TRAILBLAZER EXT'S THAT WERE COVERED BY A SPECIAL NOTICE THAT ALLOWED THE TANKS TO BE REPLACED UNDER A SPECIAL EXTENDED WARRANTY. THE REPLACEMENT COST IS $900+. THIS IS A KNOWN PROBLEM WITH 2004 TRAILBLAZER EXT, OUTSIDE OF THE NARROW VIN RANGE THAT CHEVROLET WILL ADMIT TO. ALL 2004 EXT'S SHOULD BE INCLUDED IN THE EXTENDED WARRANTY. OUR VEHICLE JUST TURNED 60,000 MILES. *TR

3RQ17002 · 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.

Status: closed (inferred from source dates) · Fuel System, Gasoline:delivery:fuel Pump
DURING THE COURSE OF THIS EA INVESTIGATION, ODI OBSERVED THAT THE MAJORITY OF THE COMPLAINTS (88%) AND WARRANTY CLAIMS (94%) WERE REPORTED FOR VEHICLES THAT ARE REGISTERED FOR USE IN THE SALT BELT REGION OF THE US.THIS AREA INCLUDES 20 STATES IN THE NORTHEAST, MID ATLANTIC AND THE MIDWEST REGIONS AND THE DISTRICT OF COLUMBIA.CONSUMERS IN THE SALT BELT REGION REPORTED TO ODI THAT THEY COULD SMELL FUEL VAPORS IN THEIR VEHICLES WHILE DRIVING.UPON FURTHER EXAMINATION OF THEIR VEHICLES, THEY DISCOVERED THAT FUEL VAPORS WERE COMING OUT OF THE TOP OF THE FUEL TANK. THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
