HAVE HAD MY 2003 TRAILBLAZER LT 2WD V8 IN THE SHOP UNDER WARRANTY MANY TIMES. FIRST WAS A RECALL ON THE DRIVE SHAFT WHICH WAS REPLACED 3 TIMES. STILL HAVE A NOISE THE DEALED SAYS THEY DON'T HEAR! NEXT CAME THE TAILLIGHT RECALL. NOW I HAVE A RECURRING PROBLEM WITH A DEAD BATTERY. THIS DOESN'T HAPPEN ALL THE TIME AND NOTHING HAS BEEN LEFT ON TO CAUSE IT. I CAN GO INTO A STORE AND COME OUT TO FIND IT DEAD. WHEN YOU CHARGE THE BATTERY, THEN EITHER THE HEATED SEATS WORK IMPROPERLY, THE BLOWER WON'T COME ON, SOMETHING DIFFERENT EVERY TIME. *JB

WENT OUT TO START VEHICLE ON SEPTEMBER 18, 2004 - TUNED KEY AND NOTHING HAPPENED, NO STARTER MOTOR, NO DASHBOARD LIGHTS, NOTHING. KEY REMIANED LOCKED IN STEERING COLUMN, COULD NOT BE REMOVED. TRIED AGAIN THE NEXT MORNING (9/19) - SAME THING. TRIED AGAIN THE NEXT MORNING (MONDAY, 9/20). THE SAME THING - AT THAT POINT CALLED DEALER TO TOW VEHICLE. ABOUT 3 HOURS LATER THE TOW TRUCK CAME - TOW TRUCK OPERATOR GOT IN VEHICLE TURNED KEY - AND VEHICLE STARTED RIGHT UP JUST AS IF NOTHING WAS EVER WRONG! . STILL HAD VEHICLE TOWED TO DEALERSHIP - DEALER CHECKED BEHICLE OVER AND FOUND NOTHING WRONG. ON SATURDAY, OCTOBER 23RD, CAME OUT OF BANK AFTER RUNNING ERRNAD, TURNED KEY IN VEHICLE - NOTHING HAPPENED AGAIN. KEPT TURNING KEY OFF AND ON FOR ABOUT 10 MINUTES UNTIL VEHICLE STARTED OUT OF THE BLUE. DROVE STRAIGHT TO DEALER. DEALER REPLACED IGNITION SWITCH. VEHICLE WORKED FINE UNTIL SUNDAY, JANUARY 23RD. WENT TO START VEHICLE AND ONE AGAIN, NOTHING HAPPENED, NO LIGHTS, NO STARTER - NOTHING. KEY ALSO LOCKED IN STEERING COLUMN. DEALER TOWED VEHICLE THE NEXT DAY. DEALER COULD FIND NOTHING WRONG, THEORIZED AN INTERIOR LIGHT WAS LEFT ON (BUT I KNOW IT WASN'T). DEALER REPLACED SOME ENGINE FAN THEY THEORIZE WAS TURNING ON AFTER ENGINE TURNED OFF AND DRAINING BATTERY - I TOLD THEM THAT'S FINE BUT DOESN'T EXPLAIN WHY TRUCK WILL START DAYS AFTER AN INITIAL FAILURE. THIS INTERMITTENT FAILURE IS FRIGHTENING AS IT SEEMS TO BE A POSSIBLE PART OF A LARGER SYSTEM FAILURE - AS NOTED ON THIS WEBSITE BY OTHER OWNERS - WHEN THE TRAILBLAZER WILL FAIL AT HIGH SPEEDS ON THE HIGHWAY.

SERVICE ENGINE LIGHT CAME ON IMMEDIATELY AFTER FILLING TANK WITH GAS. TOOK TO MECHANIC AND THEY TIGHTENED THE GAS CAP AND THEN RESET THE SERVICE ENGINE LIGHT AND DROVE AROUND AND NO LIGHT CAME ON. THREE DAYS LATER THE SERVICE ENGINE SOON LIGHT CAME ON AGAIN. TOOK BACK TO MECHANIC AND THEY RAN MORE DIAGNOSTICS AND FOUND THREE CRACK S IN THE OPENING (NECK) OF THE GAS TANK. I HAD TO HAVE THE TANK REPLACED IN ORDER FOR THE VEHICLE TO FUNCTION WITHOUT THE SERVICE ENGINE LIGHT TO COME ON. A NEW GAS TANK ON A 2003 VEHICLE IS UNHEARD OF AND I WONDER HOW MANY OTHER GAS TANKS ON 2003 CHEVY TRAILBLAZERS OR OTHER GM VEHICLES HAVE HAD TO REPLACED DUE TO THIS SAME PROBLEM?? *JB

THE TRANSMISSION IS VERY SLUGGISH AT TIMES. UPON ENTERING A HIGHWAY OR PULLING OUT INTO TRAFFIC, THE VEHICLE WILL PERIODICALLY TAKE OFF VERY SLOW. IN A COUPLE INSTANCES WE WERE ALMOST HIT BY ONCOMING TRAFFIC BEFORE THE TRANSMISSION KICKED IN. UPON TAKING IT TO THE DEALER FOR THE FOURTH TIME IN LESS THAN TWO YEARS, THEY STILL INSIST THERE IS NO PROBLEM WITH THE VEHICLE BECAUSE THE ON-BOARD COMPUTER HAS NOT RECORDED ANY CODES. I'M GETTING VERY FRUSTRATED BY THIS ANSWER, BECAUSE I FEEL THE ONLY WAY THEY WILL ADMIT THE TRANSMISSION HAS A PROBLEM IS WHEN WE ARE FINALLY INVOLVED IN AN ACCIDENT, MAYBE WITH A FATALITY. I WOULD RATHER NOT GET A RESOLUTION THROUGH THIS RESULT. *AK

WE WERE INVOLVED IN AN AUTOMOBILE ACCIDENT WHILE DRIVING A 2003 TRAILBLAZER XT. A DRIVER TURNED IN FRONT OF US AT AN INTERSECTION ON A BUSY HIGHWAY WHILE WE HAD A GREEN LIGHT. I SLAMMED ON THE BRAKES SLOWING DOWN TO WHAT WE BELIEVE TO BE AROUND 35 MILES PER HOUR, AND WE HIT HEAD ON INTO THE SIDE OF HIS RANGE ROVER. NEITHER FRONT AIRBAG DEPLOYED. I SUSTAINED A BROKEN RIGHT FOOT AND MULTIPLE BRUISES TO MY KNEES. I ALSO HIT THE STEERING WHEEL WITH MY CHEST AND HAD MANY BRUISES TO MY CHEST. I AM DOING PHYSICAL THERAPY FOR THE INJURY MY SHOULDER SUSTAINED FROM HITTING THE STEERING WHEEL. THE CAR HAS AROUND $10,000 WORTH OF DAMAGE TO THE FRONT END. I REMEMBER OFFICIALS ON THE SCENE WERE SURPRISED OUR AIR BAGS DID NOT DEPLOY AND ENCOURAGED US TO LOOK INTO THAT. I AM SCARED TO HAVE THE CAR BACK. IF A HEAD-ON COLLISION LIKE THAT WILL NOT DEPLOY MY AIRBAGS, WHAT WILL? CAN I TRUST THEM IF I'M IN AN EVEN MORE SEVERE ACCIDENT. I KNOW THEY ARE NOT SUPPOSED TO GO OFF AT THE LEAST LITTLE ACCIDENT, BUT I WOULD NOT TERM THIS A SMALL ACCIDENT. *AK

305V494000 · Latches/locks/linkages:doors:latch
Oct 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.
04V527000 · Exterior Lighting:brake Lights
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.
04V046000 · Visibility:windshield Wiper/washer
Feb 4, 2004
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.
