THERE IS RUST ALL OVER THE INSIDE OF MY ENGINE, TWO EXHAUST MANIFOLD BOLTS RUSTED OFF AND I HAD AN EXHAUST LEAK. I HAD TO HAVE IT FIXED SO I TOOK IT INTO A CHEVROLET DEALER. WHILE IT WAS THERE THEY TOLD ME THAT THE GAS TANK HAD A CRACK IN IT AND HAD TO BE REPLACED, AT A COST OF OVER 700.00 DOLLARS. I CAN'T AFFORD TO HAVE THE MANIFOLD AND TANK FIXED. NOW I AM FACED WITH EITHER EXHAUST LEAKING OR GAS LEAKING. THEY SAID THE GAS TANK WAS CRACKED AT THE NECK. I CALLED GENERAL MOTORS TO STATE THAT I THOUGHT IT WAS A MANUFACTURERS DEFECT. GM CALLED THE DEALER AND THEY TOLD THEM THAT THE VEHICLE WAS IN GOOD SHAPE AND THAT THERE WAS NO SIGN OF MISUSE OR NEGLECT. GM CALLED ME BACK AND STATED THAT THE CRACK WAS DUE TO THE AGE OF THE VEHICLE AND WEAR AND TEAR. I HAVE NEVER HEARD OF A VEHICLE GAS TANK CRACKING FOR NO REASON UNLESS THERE WAS A DEFECT IN THE GAS TANK ITSELF. THE TANK IS PLASTIC AND THE NECK IS ALSO PLASTIC, IT IS ALL ONE PIECE. I FEEL THIS IS A VERY DANGEROUS PROBLEM AND THROUGH NO FAULT OF MY OWN I HAVE TO FIND A REMEDY TO THE PROBLEM. THE ONLY WAY TO TELL IF THERE IS A LEAK IS IF THE TANK IS FULL. *TR

2002 CHEVY TRAILBLAZER SERVICE ENGINE SOON LIGHT WILL COME ON ALONG WITH THE REDUCED ENGINE POWER LIGHT AND THE VEHICLE WILL NOT GO FASTER THAN 40 MPH. SOMETIMES IT WILL NOT GO MORE THAN 20 AND 10 MPH. I'VE TAKEN THE VEHICLE TO THE DEALER AND THEY CLEANED THE THROTTLE AND CHANGED SOME FILTERS AND 2 DAYS LATER....THE SAME LIGHTS COME ON AND THE ENGINE POWER IS REDUCED. THE DEALER DOESN'T KNOW WHAT THE PROBLEM IS SO THE VEHICLE CONTINUES TO DO THIS AND HAS BEEN DOING THIS FOR THE PAST 6 MONTHS. THERE WAS A RECALL ON THE CONTROL ARMS IN 2001 THAT AFFECTED THE 2002 CHEVY TRAILBLAZER. I PURCHASED MY TRAILBLAZER IN 2002 SO I DIDN'T RECEIVE ANY RECALL INFORMATION. MY CONTROL ARMS NEED TO BE REPLACED AND I WANT TO KNOW WHY MY VEHICLE ISN'T COVERED UNDER THE RECALL. *TR

AFTER THAT THE TAILGATE WHERE THE THIRD BRAKE LIGHT IS, STARTED MAKING NOISES EVERYTIME I OPENED IT, WHEN CHECKED I FOUND THAT THE PART WHERE THE REAR WINDOW IS AFFIXED TO THE TAIL GATE WHERE BROKE AND THE ESCREWS ARE HANGING BY IT SELF WHICH MADE THE REAR WINDOW LOOSE AND STANDING OUT, AND ABOUT A WEEK AGO NOW THAT I HAVE 61K MILES IN 2009 THE REAR BRAKE LIGHT WENT OFF, TOOK IT TO DEALER AND THEY TOLD ME ABOUT THE RECALL ON THOSE LIGHTS AND SO THEY FIXED IT, WHICH WHEN I PICKED UP THE SUV AND DROVE IT WITH THE FAMILY ABOUT 45 MILES TRIP WHEN SUDDENLY IT STARTED BLOWING AIR AND MAKING A STRONG AND DEEP NOISE SOUNDED LIKE A BUS OR 18 WHEELER PASSING BY, WHICH MADE US CANCEL THE TRIP AND GO BACK TO DEALER TO FIND OUT WHAT HAVE THEY DONE TO MY CAR, TAKE A GUESS, I WAS TOLD THAT IT'S COMMON ON THOSE CHEVY'S THE FAN CLUTCH TO GO OUT AND THAT IT REALLY LASTED LONG ON MY CAR AND YES IT'S SOMETHING NORMAL THAT HAPPENS, BUT IT COST ME $950.00 TO REPAIR IT YEAH SURE VERY NORMAL, IT SEEMS LIKE GM PARTS AND LABORS NOW ARE COSTING JUST AS THE GERMAN CARS.

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

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.

5RQ17002 · 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.
