I DETECTED A STRONG GAS SMELL AND TOOK THE TRUCK TO BE REPAIRED. I WAS INFORMED THAT THE FUEL PUMP MODULE WAS LEAKING DUE TO BEING RUSTED OUT. I TOOK IT TO THE DEALERSHIP (JEFF WYLER). THEY AGREED TO COVER THE REPAIR OF THE GAS TANK AND THE LABOR (DUE TO A SPECIAL WARRANTY DUE TO OTHER FUEL LEAK PROBLEMS), BUT WOULD NOT COVER THE COST ( $454 + TAX) WHICH WAS THE PART THAT WAS THE CAUSE OF THE PROBLEM. THE ASSEMBLY OF THIS PART IS UNPAINTED MEDAL AND RUSTS VERY EASILY (MOST OTHER COMPANY USE PLASTIC ASSEMBLES TO PREVENT THIS VERY PROBLEM). THE LOCATION OF THIS PART MAKES IT ALMOST IMPOSSIBLE TO WASH, IN ORDER TO REMOVE ANY SALT OR OTHER CORROSIVE ELEMENTS. I DO NOT SEE A WAY THAT I COULD HAVE PREVENTED THE RUSTING OF THIS PART. I BELIEVE THIS IS A DESIGN DEFECT THAT CHEVY SHOULD HAVE TO CORRECT, DUE TO THE FACT THAT IT COULD HAVE VERY EASILY CAUSE A FIRE TO THE VEHICLE DUE TO THE AMOUNT OF FUEL/VAPOR LEAKING. *TR

HEADLIGHTS BECOME INOPERATIVE WHEN DRIVING: WHEN DRIVING AT NIGHT THE HEADLIGHTS STOP WORKING I HAVE BEEN FORCED TO PULL OVER AND WAIT UNTIL THE LIGHTS BECOME OPERATIVE. I HAVE DISCUSSED THIS PROBLEM WITH MY LOCAL DEALER AND HE STATED THAT THERE WAS KNOW VISUAL REASON THAT HE COULD FIND ON WHY THIS WAS HAPPENING HE ADVISED THAT I SHOULD BRING THE CAR IN THE NEXT TIME IT HAPPENED, THIS PRESENTS A PROBLEM BECAUSE IF THE LIGHTS FAIL IN THE DAY LIGHT HOURS I WOULDN'T BE ABLE TO SEE THE FAILURE ONLY AT NIGHT CAN I VISUALLY SEE THAT MY HEADLIGHTS HAVE FAILED. THE HEADLIGHT FAILURE CAN LAST FOR MINUTES TO HOURS I HAVE BEEN DRIVING ON THE HIGHWAY AT 65 MPH AND MY HEADLIGHTS COMPLETELY FAIL. *TR

WE PURCHASED OUR 2003 TRAILBLAZER EXT USED THIS SUMMER. IT HAD ABOUT 50,000 MILES ON IT. WE'VE NOTICED THAT WHEN WE'RE ON THE ROAD FOR OVER 2 HOURS AT A TIME, THE SPEEDOMETER BECOMES DANGEROUSLY UNRELIABLE. MOST RECENTLY, MY HUSBAND WAS PULLED OVER FOR AN UNSAFE LOW SPEED -- UNTIL THE STATE POLICEMAN SAW THAT THE SPEEDOMETER WAS REGISTERING 20 MILES AN HOUR WITH THE CAR IN PARK AND THE ENGINE TURNED OFF. WE HAVE HAD MULTIPLE FAILURES. RESETTING IS SOMETIMES POSSIBLE BY CONTINUALLY RESTARTING THE CAR, BUT NOT ALWAYS, AND NOT WITH ANY RELIABILITY. BY CONTINUALLY RESTARTING I'M TALKING 30-50 RESTARTS. THE WEAR AND TEAR ON THE STARTER THEREFORE IS UNACCEPTABLE. THIS VEHICLE SHOULD BE COVERED BY THE RECALL, BUT WE'VE NOT BEEN NOTIFIED AND WHEN WE'VE TAKEN IT TO DEALERSHIPS, WE HAVEN'T EVEN BEEN NOTIFIED OF THE RECALL. THE PROBLEM HAS NO OTHER DISCERNIBLE PATTERN AND HAS HAPPENED APPROXIMATELY 6 TIMES IN THE 8 MONTHS WE'VE HAD THE CAR. *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.

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.
