I WENT TO GO IN REVERSE AGAIN BUT THE TRUCK WOULD NOT GO INTO REVERSE AND COULD HEAR A LOUD WHINING FROM THE MOTOR. I THIS JUST HAPPENED TO DAY BUT I FIGURE IT'S THE TRANSMISSION. ALSO, WHEN I BOUGHT THE TRUCK I HAD PROBLEMS WITH THE TEMP. SENSOR AND THE AIR CONDITIONING THE DEALER TOOK CARE OF THE PROBLEM WITH THE AIR BUT THE OUTSIDE TEMP. SENSOR IS STILL BROKE. I DON'T KNOW WHICH IS WORSE THE FAILURE OF THE TRANSMISSION OR, SEEING ALL THE LIKE COMPLAINTS ON THIS SITE WITH NO ACTION. *JB

TRANSMISSION COOLANT PIPES: ON THE AFTERNOON OF NOVEMBER 12, I WAS DRIVING ON A LOCAL FREEWAY I BEGAN EXPERIENCING DIFFICULTIES MAINTAINING SPEED. WHILE THE ENGINE HAD FULL POWER, I HAD TO PULL OVER AS MY VEHICLE EFFECTIVELY LOST POWER TO THE WHEELS. AT THIS TIME, I HAD THE VEHICLE TOWED TO THE LOCAL CHEVROLET DEALER WHERE I HAVE THE VEHICLE SERVICED. THE VEHICLE HAS ALWAYS BEEN REGULARLY SERVICES AT GM DEALERS. THE FOLLOWING MONDAY, MY SUSPICION OF A TRANSMISSION FAILURE WAS CONFIRMED. SEVERAL DAYS LATER, THE OLD TRANSMISSION WAS REPLACED. AT THAT TIME, THE TRANSMISSION COOLANT PIPE WAS DISCOVERED TO HAVE BEEN RUSTED THROUGH AND THIS WAS IDENTIFIED AS THE LIKELY CAUSE OF MY TRANSMISSION FAILING. I ULTIMATELY HAD TO HAVE THE TRANSMISSION AND THAT COOLANT PIPE REPLACED AT THE COST OF SEVERAL THOUSAND DOLLARS. I BELIEVE A STRONG CASE EXISTS FOR CALLING ATTENTION TO A NEED TO INSPECT AND PERHAPS REPLACE CRITICAL UNDERBODY FLUID PIPES ON SIMILAR VEHICLES DUE TO THE LIKELIHOOD OF RUST-THROUGH AND OTHER FAILURES THAT COULD CAUSE SUBSTANTIAL DAMAGE TO VEHICLES. *JB

MY TRANSMISSION WENT IN JANUARY OF 2005. IT IS NOW JULY AND THE SAME THING HAPPENED AGAIN. I HAD TO FIGHT WITH THE DEALERSHIP THEN BECAUSE I ONLY HAD THE VEHICLE FOR 4 MONTHS AND I AM FIGHTING WITH THEM AGAIN. IT IS THE SAME PROBLEM.

SMALL "CLUNKING" NOISE FROM UNDER VEHICLE WHEN SHIFTING FROM PARK TO REVERSE OR DRIVE. "CLUNKING ALSO EVIDENT WHEN SLOWING TO A STOP. ULTIMATE TRANSMISSION FAILURE OCCURRED WHILE ACCELLERATING FROM A STOP. A VERY LOUD "CLUNCK" WAS HEARD FROM UNDER THE VEHICLE FOLLOWED BY A LOUD WIRRING NOISE. THE VEHICLE WOULD NOT SHIFT FROM FIRST GEAR AFTERWARDS UNTIL ABOUT 40 MPH. THE "WIRRING" NOISE CONTINUED WHEN THE VEHICLE WAS STOPPED AND THE TRANSMISSION WOULD NOT SHIFT INTO REVERSE. THE DEALER'S MECHANIC OVERHAULED THE TRANSMISSION AND REPLACED THE FOLLOWING "WORN" PARTS: SUN GEAR SHELL, SUN GEAR, 3-4 CLUTCH. VEHICLE HAD 40000 MILES AT TIME OF FAILURE.

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.

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.

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.
