I OWN A 2003 CHEVROLET TRAILBLAZER EXT. I SMELLED A STRONG ODOR OF GAS EMANATING FROM MY VEHICLE RECENTLY. AFTER SOME INVESTIGATING, I DISCOVERED THAT THERE WAS FUEL LEAKING OUT OF THE TOP OF MY FUEL TANK ONLY WHILE THE ENGINE WAS RUNNING. I DROPPED THE FUEL TANK AND DISCOVERED THAT THE METAL NIPPLES FROM THE TOP OF THE FUEL PUMP THAT CONNECT THE FUEL LINES TO THE FUEL PUMP WERE COMPLETELY RUSTED AND WHEN THE VEHICLE WAS RUNNING, FUEL WAS JETTING ALL OVER THE UNDER CARRIAGE OF MY VEHICLE. THE METAL RING THAT HOLDS THE FUEL PUMP TO THE TANK WAS ALSO SEVERELY RUSTED. GM SHOULD KNOW BETTER THAN TO PUT EXPOSED METAL FITTINGS IN A RECESSED TANK WHERE IT IS SUBJECT TO RUST, SALT, CORROSION ETC. I HAD TO REPLACE THE FUEL PUMP AT A SIGNIFICANT COST. I ALSO BELIEVE THAT THIS COULD BE A POTENTIAL FIRE HAZARD AS THE FUEL WAS JETTING ALL OVER THE UNDERCARRIAGE AND ITS PROXIMITY TO THE EXHAUST. MY FITTINGS WERE SO BRITTLE THAT YOU COULD CRUSH THEM WITH YOUR BARE HANDS. LEFT UNCHECKED, UNDOUBTEDLY I WOULD HAVE EXPERIENCED A LOSS OF POWER AND WOULD HAVE BEEN A HAZARD TO THE OTHER VEHICLES ON THE ROAD-YET ALONE PROBABLY WOULD HAVE BEEN STRANDED WHEN THE VEHICLE DIED. THE OLD PARTS ARE AVAILABLE FOR INSPECTION. A FUEL PUMP SHOULD LAST MORE THAT (3) YEARS IN MY OPINION. THIS IS A DESIGN AND/OR PRODUCT FAILURE. *JB

DRIVER SIDE SEAT DETACHED FROM SEAT FRAME RECENTLY. I TURNED TOWARDS THE BACK OF MY CHEVY TRAILBLAZER EXT TO TALK TO MY KIDS AND THE RIGHT SIDE OF THE DRIVERS SEAT BROKE FROM THE SEAT FRAME. UPON INSPECTION, THERE'S A FLIMSY PIECE OF METAL HOLDING THE SEAT TO THE SEAT FRAME. WHEN I BROUGHT IT IN TO THE SERVICE DEALER, HE SAID THE WHOLE SEAT NEEDS TO BE REPLACED AT A COST OF OVER $800. HE SAID I CAN CALL GM TO REPORT THE ISSUE AND THAT THEY MAY OFFER ME A DEAL TO SPLIT THE COST SINCE THE VEHICLE IS OUT OF WARRANTY. I BELIEVE THIS IS A MANUFACTURER'S DEFECT BECAUSE IT HAS NEVER HAPPENED BEFORE IN ANY CAR THAT I'VE OWNED IN THE PAST. WAITING RESOLUTION TO MY COMPLAINT FROM GM, BUT THIS IS CONDITION MAY LEAD TO FUTURE ACCIDENTS!! *JB

MY WIFE AND I HAVE BEEN SMELLING GAS OUTSIDE AND WITH OUR 2003 CHEVY TRAILBLAZER EXT. I BROUGHT IT TO MY MECHANIC AND HE FOUND A SPLIT AT THE TOP OF THE FUEL TANK (NECK FILLER PLATE). I CALLED THE CHEVY NUMBER AND BROUGHT THE VEHICLE TO CROTON AUTO PARK. THEY FOUND THE SAME PROBLEM AND SAID IT WOULD COST MY OVER $750 TO REPLACE THE TANK. I VIEW THIS ISSUE TO BE A MANUFACTURES DEFECT AND ESCALATED THE MATTER TO CHEVY. THEY ARE OFFERING A 50% REBATE TO FIX. I DON'T BELIEVE I SHOULD PAY FOR THIS DEFECT. I HAVE RESEARCHED THE ISSUE AND FOUND MORE PEOPLE THAT HAD THE SAME PROBLEM WITH THEIR CHEVY TRAILBLAZER (SAME MODEL AND YEAR). REFER TO WEB SITE: HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-TRAILBLAZER/TC82DA8F4UEJOJ6VF/P2#LASTPOST. I AM WAITING ON CHEVROLET'S DECISION AS TO WHO IS GOING TO PAY FOR THIS. I CANNOT DRIVE THIS AUTOMOBILE IN ITS CURRENT CONDITION OUT OF EXTREME FEAR OF FIRE AND EXPLOSION!!!!!!! PLEASE FEEL FREE TO CALL ME FOR MORE DETAILS. *JB

WE HAVE A 2003 CHEVY TRAILBLAZER AND HAVE HAD NOTHING BUT PROBLEMS WITH IT SINCE WE BOUGHT IT BRAND-NEW. IT WAS BACK IN THE SHOP WITHIN 2 MONTHS OF PURCHASING IT DUE TO NEEDING THE ENTIRE FUSE BOX REPLACED. IT HAS BEEN BACK IN FOR REPAIRS NUMEROUS TIMES FOR ENGINE FAILURE AND PROBLEMS WITH THE GAUGES. WE HAVE HAD THE ENTIRE SPEEDOMETER PANEL REPLACED AT OUR EXPENSE AND SPENT $1200 ON REPAIRS RELATED TO THE TRANSMISSION. WE RETURNED IT TO THE DEALER 2 MONTHS LATER DUE TO THE EXACT SAME DIFFICULTIES WITH THE ENGINE STALLING AND THEY TOLD US THE COMPUTER NEEDED TO BE REPROGRAMMED. WE PAID FOR THAT AND NOT ONE WEEK LATER THE VEHICLE IS CONTINUING TO STALL ON US. IT HAS BEEN EXTREMELY DANGEROUS AND IN AT LEAST ONCE CIRCUMSTANCE HAS ALMOST CAUSED AN ACCIDENT. THIS VEHICLE IS UNSAFE TO DRIVE. THE ENGINE HAS QUIT ON US ON AT LEAST 12 DIFFERENT OCCASIONS WITHIN THE LAST 2 MONTHS, DESPITE BEING IN FOR REPAIRS TWICE FOR THE SAME ISSUE. WE ARE EXTREMELY DISAPPOINTED IN THIS VEHICLE AND ARE SADDENED BY THE FACT THAT WE HAVE SPENT SO MUCH MONEY AND TO NO AVAIL. WE HAVE SINCE LEARNED THAT MANY, MANY OTHER PEOPLE ARE EXPERIENCING THE SAME TROUBLE. WE ARE TAKING IT BACK TO THE DEALER TOMORROW AND TRADING IT IN. WE NEED SOMETHING THAT IS RELIABLE AND SAFE OUT ON THE ROADS. AND THIS VEHICLE IS DEFINITELY NOT SAFE.

I TOOK IT TO THE DEALERSHIP TO HAVE IT LOOKED AT AND THEY SAID THE GAS TANK INLET LINE HAD A CRACK IN IT AND I NEEDED A NEW TANK, IT WOULD COST $906. I DID SOME RESEARCH AND THERE IS A SPECIAL POLICY ADJUSTMENT #05012 FOR 2002 TRAILBLAZERS. THE DEALERSHIP SAID THEY WOULD REPLACE IT FOR FREE CAUSE THEY ARE THE SAME TANKS ON THE 2002 AND 2003, BUT I STILL HAD TO PAY $87.00 FOR THE DIAGNOSTIC FEE. I TOLD THE DEALERSHIP AND CUSTOMER SERVICE ALL THE VEHICLES SHOULD BE RECALLED AND CHANGED BEFORE SOMEONE GETS SERIOUSLY HURT FROM ON EXPLODING. THEY TOLD ME THEY ARE DOING SOMETHING ABOUT IT, THEY ARE REPLACING MY TANK. BUT WHAT ABOUT ALL THE OTHER TANKS OUT THERE THAT COULD BE LEAKING, AND IF SOMEONE REAR ENDS THEM, OR A ELECT SHORT CAUSES A SPARK, A CIGARETTE BEING FLICKED OUT THE WINDOW, SOMEONE NEEDS TO DO SOMETHING ABOUT IT BEFORE SOMEONE GET KILLED. *NM

MY 2003 TRAIL BLAZER CHECK ENGINE LIGHT WAS ON SO I TOOK IT IN TO SEE WHY IT WAS ON. THE MECHANIC REPLACED THE GAS CAP RESET THE ENGINE LIGHT AND SENT ME OFF. TWO DAYS LATER, IT CAME BACK ON SO I TOOK IT BACK. THIS TIME THEY REPLACED A SOLENOID AND RESET THE CHECK ENGINE LIGHT. ONE DAY LATER IT CAN BACK ON. TIRES CARE PLUS STATED TO TAKE IT TO THE CHEVY DEALER BECAUSE THEY DID NOT KNOW WHAT TO DO WITH IT. I TOOK IT TO THE DEALER AND THEY STATED IT WAS A FUEL FILTER FITTING LEAK AND THAT THE ENTIRE GAS TANK AND FUEL HOSE NEEDED TO BE REPLACED AT A COST OF $1000.00. I OPTED NOT TO HAVE IT FIXED SO THEY SENT ME HOME WITH NO WARNING OR FURTHER EXPLANATION. I WENT HOME AND DID SOME RESEARCH ON THE INTERNET ABOUT THIS PROBLEM. AS IT TURNS OUT, THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THE FUEL FILTER FILLING BREAKING FROM THE FUEL TANK. FOUR DAYS LATER, I WENT TO FILL UP MY CAR WITH GAS AND ALL THE GAS RAN OUT OF THE CAR ALL OVER THE PAVEMENT. I CALLED THE CHEVY DEALER, STATED WHAT HAPPENED AND HAD IT REPAIRED FOR $1000.00 (THE ENTIRE GAS TANK AND FUEL FITTING ON A 2003 CAR!). FROM WHAT RESEARCH I HAVE DONE, THE 2002 TRAILBLAZER HAVE BEEN RECALLED BUT THE 2003 HAVE NOT AND CHEVY HAS NOT REDESIGNED THE TANK. THERE WAS A LADY THAT HAD TO REPLACE HER TANK TWICE! IS THIS NOT A HAZARD? I KEPT SMELLING GAS OUTSIDE MY CAR BUT ASSUMED THAT IT WAS BECAUSE I HAD OVERFILLED THE TANK. *JB

Official recalls
3Oct 27, 2005
CERTAIN SPORT UTILITY VEHICLES HAVE A REAR SIDE CLOSURE LATCH THAT MAY NOT LATCH OR UNLATCH DUE TO CORROSION CAUSED BY ROAD SPLASH, SUCH AS WATER AND ROAD SALT. THESE VEHICLES WERE ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE FOLLOWING STATES: CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA.
Consequence & remedy
Consequence: IF THE DOOR IS NOT LATCHED PROPERLY AND IT GOES UNNOTICED, IT MAY OPEN WHILE THE VEHICLE IS IN MOTION. IF AN UNBELTED OCCUPANT FELL OUT OF THE VEHICLE, PERSONAL INJURIES COULD OCCUR.
Remedy: DEALERS WILL INSTALL A SEAL ALONG THE LOWER PART OF THE ROCKER PANEL TO PREVENT INTRUSION OF CORROSIVE MATERIAL, AND INSPECT THE REAR SIDE CLOSURE LATCHES. FUNCTIONAL LATCHES WILL BE CLEANED AND LUBRICATED. NON-FUNCTIONING LATCHES WILL BE REPLACED. THE RECALL BEGAN ON FEBRUARY 24, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR ISUZU AT 1-800-255-6727.

ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE.
Consequence & remedy
Consequence: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE TAIL LAMP/STOP LAMP ASSEMBLIES, AND IF NECESSARY, REPLACE THEM. THE RECALL BEGAN ON NOVEMBER 22, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, BUICK AT 1-866-608-8080, OR GMC AT 1-866-996-9463.

CERTAIN SPORT UTILITY VEHICLES HAVE WINDSHIELD WIPER SYSTEMS THAT WILL NOT TURN ON, CEASE OPERATION WHILE IN USE, FAIL TO TURN OFF/ON BY THEMSELVES (MOISTURE SENSITIVE WIPER SYSTEM), OR HAVE CONTINUOUS WINDSHIELD WASHER PUMP OPERATION BECAUSE THE PRESENCE OF WATER WITHIN THE WIPER MODULES CAN EITHER CAUSE A SHORT CIRCUIT OR CAN LEAD TO THE CORROSION OF COMPONENTS WITHIN THE MODULE.
Consequence & remedy
Consequence: DEPENDING ON THE OCCURRENCE AND WEATHER SITUATION, DRIVER VISIBILITY COULD BE REDUCED, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL COVER THE WINDSHIELD WIPER MODULE VENT HOLE WITH A PATCH. ALSO, THE WIPER MOTOR, CIRCUIT BOARD, AND ELECTRICAL CONNECTOR WILL BE INSPECTED TO SIGNS OF WATER INTRUSION AND/OR CORROSION AND BE REPLACED AS REQUIRED. THE RECALL BEGAN JULY 6, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR GMC AT 1-866-996-9463.

6RQ17002 · 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.

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.
