I PURCHASED THE VEHICLE WITH APPROXIMATELY 63,000 MILES ALREADY ON IT. WITHIN A MONTH I NOTICED THE SPEEDOMETER WAS DOING FUNNY THINGS LIKE READING 100MPH WHEN I WAS ONLY DRIVING ABOUT 25MPH. I CONTACTED A DEALER AND WAS TOLD IT WOULD COST $500 TO REPAIR. WE DO NOT HAVE THAT KIND OF MONEY SO I LEFT IT. THE PROBLEM CONTINUED UNTIL THE SPEEDOMETER STOPPED WORKING ALTOGETHER. I HAD LEARNED HOW TO GAUGE MY SPEED BY USING THE TAKOMETER BUT THAT STARTED TO GO SHORTLY AFTER THE SPEEDOMETER. NOW MY BATTERY GAUGE IS STARTING TO SHOW SIGNS OF FRITZING. I HAVE READ ONLINE THAT THIS IS A VERY COMMON PROBLEM WITH THESE VEHICLES AND THAT GM HAS NOT ISSUED A RECALL. I NOW HAVE A GPS WHICH CAN TELL ME MY SPEED BUT THE BATTERY GAUGE IS A DEFINATE SAFETY ISSUE. THANK YOU! *TR

ABOUT A MONTH AGO I STARTED TO SMELL GAS VAPORS WHEN I DROVE MY CAR. ONE DAY I WAS ON THE HIGHWAY AND A PERSON NEXT TO ME HONKED HIS HORN AND TOLD ME THAT HE SAW GAS LEAKING UNDER MY CAR. I WAS NEAR PEP BOYS AND PULLED IN THE PARKING LOT. I SHUT MY CAR OFF AND LOOKED UNDERNEATH IT. I SAW A LOT OF GAS DRIPPING FROM UNDER MY FUEL TANK AND FALLING ONTO THE GROUND. I WENT INSIDE PEP BOYS AND TOLD THEM THE PROBLEM. IT WAS NEARLY CLOSING TIME SO I LEFT THE CAR OVERNIGHT AND CALLED FOR A RIDE HOME. PEP BOYS CALLED ME THE NEXT MORNING AND GAVE ME AN ESTIMATE OF $270 JUST TO DROP THE TANK AND LOOK AT WHAT MAY HAVE CAUSED THE LEAK. THEY SAID IT WAS LIKELY A BAD FUEL PUMP OR BAD FUEL LINES. I ASKED THEM ANOTHER ESTIMATE ON HOW MUCH IT WOULD COST TO FIX MY GAS LEAK. THEY SAID IT WOULD COST AROUND $600 TO $800 TO FIX MY CAR IF THE FUEL PUMP OR BAD FUEL LINES WERE REALLY THE PROBLEM. I TOLD THEM TO NOT WORK ON THE CAR AND SAID THAT I WOULD PICK IT UP. SO I TOWED THE CAR BACK HOME AND PULLED IT INTO THE GARAGE. THIS IS THE FIRST TIME THAT MY CAR HAS LEAKED GAS. THE NEXT DAY I TOOK OFF THE FUEL TANK TO CHECK WHERE THE LEAK WAS COMING FROM. WHEN I LOOKED AT THE TOP OF THE TANK, THE FUEL PUMP WAS CORRODED AND THERE WAS GAS ON THE OUTSIDE OF THE PUMP. ALSO WHEN I TOOK THE TANK OFF, THE FILLER NECK HOSE WAS CRACKED AND WAS NOT CONNECTED TO THE GAS TANK. I CALLED A JUNK YARD AND ORDERED A FUEL PUMP FOR $150. I ALSO CALLED MY LOCAL DEALER AND TOLD THEM MY ISSUE. THEY SAID THAT MY CAR HAD TOO MANY MILES ON IT AND WAS NOT COVERED BY WARRANTY ANYMORE. SINCE THE DEALER COULD NOT HELP ME, I CALLED GENERAL MOTORS CUSTOMER SERVICE AND ISSUED A SAFETY DEFECT ON MY VEHICLE. THEY SAID THAT THERE WAS A EXTENDED SPECIAL COVERAGE ON MY VEHICLE THAT MIGHT COVER THE REPAIR. I CALLED ANOTHER DEALERSHIP AND I AM WAITING FOR THEM TO CALL ME BACK. RIGHT NOW MY CAR HAS BEEN IN THE GARAGE FOR ALMOST A MONTH. THE ONLY WAY TO FIX IT IS TO BUY A NEW GAS TANK FOR $500. *TR

I HAVE A PROBLEM SIMILAR TO MANY OTHERS. I HAVE RECENTLY PURCHASED A 2003 CHEVROLET TRAILBLAZER. I HAVE ENCOUNTERED A PROBLEM WITH THE SPEEDOMETER ON THIS VEHICLE. THE SPEEDOMETER OCCASSIONALLY STOPS WORKING ENTIRELY FROM TIME TO TIME AND OTHER TIMES, HAS A MIND OF IT'S OWN AND DECIDES TO MAKE A RANDOM NUMBER THE ZERO MARK AND INCREASE SPEED FROM THAT POINT. I KNOW THAT THIS IS A SAFETY ISSUE AS THERE ARE TIMES THAT I HAVE NO IDEA HOW FAST I AM TRAVELING. I HAVE SINCE TAKEN THIS MATTER TO GENERAL MOTORS IN AN ATTEMPT TO GIVE THEM AN OPPORTUNITY TO RECTIFY AN UNSAFE SITUATION. IN RESPONSE, THEY ASKED ME TO TAKE THE VEHICLE INTO A CERTIFIED GM DEALER FOR A VEHICLE DIAGNOSTIC AND REPAIR. I DID JUST THAT. MY VEHICLE WAS FOUND TO HAVE A PROBLEM WITH THE INSTRUMENT CLUSTER. THE DEALER WAS NICE ENOUGH TO INFORM ME THAT THERE HAVE BEEN SEVERAL RELATED PROBLEMS THAT GM HAS ISSUED A RECALL FOR... UNFORTUNATELY, I SEEM TO HAVE THE ONLY MODEL IN THIS VEHICLE CLASS THAT IS NOT COVERED IN THIS RECALL. AND GM WAS NICE ENOUGH TO OFFER TO DO ABSOLUTELY NOTHING IN MY CASE... WHICH INCLUDES NOT REFUNDING THE COST OF THE DIAGNOSTIC THAT THEY REQUESTED IN ORDER TO GATHER THEIR INFORMATION. IN MY DISAPPOINTMENT, I HAVE DONE SOME ONLINE RESEARCH AND COME ACROSS SEVERAL LAWSUITS AGAINST GM FOR THIS EXACT PROBLEM... SOME OF WHICH EVEN INCLUDE THE TRAILBLAZER. MY QUESTION IS THIS: DO I HAVE ANY OTHER COURSE OF ACTION? ALSO, HAS THERE ALREADY BEEN A COMPLAINT SIMILAR TO THIS THAT MAY BE OF ASSISTANCE TO ME? *TR

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.
Nov 1, 2004
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.
