AWFUL, AWFUL SAFETY HAZARD ON MY 2003 TRAILBLAZER!!!!!THE HATCH BACK/LIFT GATE WON'T OPEN - TAILGATE WINDOW EXPLODES IN THE MECHANICS FACE KNOCKING HIM TO THE GROUND. REPRESENTATIVES FROM GM AND FROM THE DEALERSHIP DENY THAT THIS HAS HAPPENED IN ANY OTHER 2003 TRAILBLAZERS. THAT IS A LIE!!!! SEE OTHER COMPLAINTS ON THIS VERY WEBSITE. COMPLAINT #10121982, ALSO COMPLAINT #10150063, AND COMPLAINT #10075392. THEN CHECK OUT COMPLAINT #10038988, #10075392 AND #10061979 REGARDING THE HATCHBACK TAILGATE BREAKDOWNS. COMPLAINT #10121982 TELLS OF A CHILD THAT IS INJURED BY THE EXPLODING GLASS IN THE TAILGATE. REMEMBER THE DOUBLE SIDED TAPE THAT THE DEALERSHIP TELLS ME THAT GM USES TO HOLD ON THE HIGH MOUNT STOP LIGHT AND TRIM??? IN COMPLAINT #10038988 THE COMPLAINANT WAS ALSO TOLD ABOUT THE DOUBLE SIDED TAPE. ARE YOU INVESTIGATING THIS PROBLEM????? I AM DRIVING A VERY UNSAFE CAR AND I WILL FIGHT UNTIL I GET SOME ACTION. I HAVE BEEN WITHOUT A CAR NOW FOR 10 DAYS. THE DEALERSHIP INSISTED THAT WE TURN THIS CLAIM INTO MY INSURANCE. $2,650 CLAIM FOR WHAT THE DEALERSHIP SAID WOULD COST $25. THE DEALERS BODY SHOP ALSO EXPLAINED THAT THE HIGH MOUNT STOP LIGHT AND TRIM ARE ATTACHED WITH DOUBLE FACE TAPE AND IF THEY COME LOOSE THEY BIND INSIDE THE HATCHBACK. I DON'T FEEL IT IS MY INSURANCE COMPANY'S RESPONSIBILITY TO PAY FOR SOMETHING THE DEALER CAUSED. THIS IS A VERY DANGEROUS PROBLEM CREATED BY CHEVEROLET'S POOR DESIGN. WHY HAVEN'T THEY DONE A RECALL ON THIS. THERE ARE NUMEROUS OTHER COMPLAINTS ABOUT THE SAME HATCHBACK FAILURE. THE GLASS COULD EXPLODE ON ME ON MY GRANDKIDS OR ANOTHER MECHANIC. I WILL BE NERVOUS EVERYTIME I OPEN THAT HATCHBACK AND I WILL NEVER, NEVER BUY A GENERAL MOTORS CAR AGAIN. THE DEALERSHIP TREATED MY HUSBAND AND I TERRIBLY. THEY KNEW THEY HAD THE UPPER HAND IN THE SITUATION AND THEY KNEW THERE WAS NOTHING WE COULD DO. *JB

MY 2003 CHEVROLET TRAILBLAZER EXT HAS HAD A POWER STEERING PROBLEM STARTING AROUND 15K MILES. THE POWER STEERING GOES IN AND OUT WITH NO WARNINGS. WHEN I HAVE NOTICED THIS, THE PROBLEM GOES AWAY IF YOU PUSH THE GAS PEDAL TO SPEED UP, BUT IF YOU DO NOT THE POWER STEERING GOES COMPLETELY OUT. I HAVE HAD SEVERAL CLOSE CALLS WHILE I WOULD BE TURNING INTO A PARKING SPACE AND THE STEERING WOULD GO OUT. YOU DO STILL HAVE CONTROL OF THE STEERING BUT IT IS EXTREMELY HARD TO TURN THE WHEEL. I HAVE SEVERAL FRIENDS AND NEIGHBORS WITH THE SAME STYLE TRUCK AND THEY ALL HAVE EXPERIENCED A PROBLEM AS WELL. I FIND IT HARD TO BELIEVE THAT THIS PROBLEM HAS NOT BEEN A HUGE ISSUE. MY DEALER, WHICH IS VERY GOOD, HAS NOT RECEIVED ANY NOTIFICATION ABOUT THIS BEING AN ISSUES FROM THE MANUFACTURING, EVEN AFTER THEY HAVE RECEIVE SEVERAL COMPLAINTS THEMSELVES ON THIS ISSUE. *NM

2003 CHEVY TRAILBLAZER EXT. SERVICE ENGINE LIGHT WENT ON ABOUT A MONTH AGO. SERVICE AT DEALERSHIP SAID WE NEEDED A NEW GAS CAP. THIS DID NOT FIX THE PROBLEM. LIGHT WENT BACK ON, TOOK IT BACK THIS PAST SATURDAY. WAS TOLD GOOSENECK TO GAS TANK IS CRACKED, RESULTING IN A FUEL LEAK (I HAVE AN INFANT). WAS ALSO TOLD THAT THE TRAILBLAZERS OFTEN COME IN FOR THAT PROBLEM, THAT THERE WAS A RECALL. THE DEALERSHIP WANTS OVER $700.00 TO REPLACE THE TANK. WE HAVE A NEW BABY AND ARE DOWN TO ONLY ONE HOUSEHOLD INCOME. I CALLED CHEVROLET THIS MORNING AND WAS TOLD THAT THERE IS A RECALL FOR THIS EXACT PROBLEM BUT THAT MY VIN IS NOT ON THEIR LIST SI I MUST HAVE "RUN SOMETHING OVER" THAT CRACKED THE GOOSENECK. I DON'T KNOW MUCH ABOUT CARS BUT I KNOW SOMETHING BEING RUN OVER WOULD NOT MAKE IT TO THE GOOSENECK. CHEVY ADMITTED THIS DEFECT TO ME- JUST BECAUSE MY VIN DID NOT MAKE THEIR LIST (ALLEGEDLY) DOES NOT MEAN THAT IT SHOULD NOT BE ON IT. IT WOULD COST THEM MORE, IN MY OPINION, IN LAW SUITS AND NEGATIVE PUBLICITY IF, GOD FORBID, MY FAMILY DIES IN AN EXPLOSION BECAUSE THIS TRUCK BLOWS UP IN THE DRIVEWAY THAN IT WOULD IF THEY WOULD INCLUDE MY VIN ON THEIR LIST AND PAY FOR THEIR DEFECT. *UB

WHILE DRIVING, MY SPEEDOMETER STOPPED WORKING COMPLETELY. I HAVE HAD IT CHECKED BY BOTH A GM DEALER AND AN INDEPENDENT REPAIR SHOP. I WAS TOLD THE ENTIRE "CLUSTER" WOULD HAVE TO BE REPLACED. I WAS ALSO TOLD THAT THERE ARE MANY OF THESE PROBLEMS AND THAT THERE IS A 2-3 WEEK DELAY IN GETTING THE PART SHIPPED. I WAS ALSO TOLD IT WOULD COST ABOUT $400 TO GET IT FIXED. MY CAR IS A 2003 AND HAS ABOUT 81,000 MILES ON IT. A SPEEDOMETER IS NOT LIKE AN ALIGNMENT, WEAR AND TEAR ITEM, OR NEGLECT OF HAVING IT SERVICED. IT IS OBVIOUSLY A SAFETY CONCERN BECAUSE OF SPEED, THE INABILITY TO GET THE PART IN A TIMELY MANNER AND THE UNWILLINGNESS OF GM TO COVER THE REPAIR. *JB

THE INCIDENT OCCURRED WHILE DRIVING HOME AFTER DROPPING MY SON OFF AT WORK ON I-95. I WAS TRAVELING BETWEEN 65 AND 70 MPH AND PASSING A SEMI WHEN MY VEHICLE SUDDENLY AND WITH NO PRIOR WARNING SHIFTED INTO SECOND GEAR. LUCKILY I WAS ABLE TO MAINTAIN CONTROL OF MY CAR AND ABLE TO DRIVE IT THE REST OF THE WAY HOME. ON MONDAY I DROVE MY VEHICLE AS INSTRUCTED TO THE MJ SULLIVANS, THE DEALERSHIP IN WHICH I BOUGHT THE TRAILBLAZER, FOR SERVICE. I WAS THEN NOTIFIED THAT THE STATOR SUPPORT BUSHINGS IN THE TRANSMISSION FAILED AND THAT IT WOULD ACTUALLY BE CHEAPER TO REPLACE THE TRANSMISSION. INTERESTINGLY, THE NEW TRANSMISSION COMES WITH A 10YR/100K MILE WARRANTY AND MY VEHICLE HAS ONLY 69000 MILES OF HIGHWAY MILES. ASKED THE SERVICE ENGINEER ABOUT HOW UNUSUAL THIS TYPE OF FAILURE IS AND THEY TOLD ME HIGHLY CONSIDERING THE WEAR ON OTHER PARTS IN THE TRANSMISSION. WE DO NOT TOW OR HAVE HILLS IN OUR AREA AND FOR THE MOST PART ONLY TRAVEL ON THE HIGHWAY SO I WOULD NOT SUSPECT THAT WE WOULD BE PUTTING A HIGH LEVEL OF WEAR AND TEAR ON IT. WE HAD THE TRANSMISSION REPLACED. *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.
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.
