THE DRIVERS SEAT HEATER GOT VERY HOT AND THEN STOPPED WORKING SHORTLY AFTER. I DID AN INTERNET SEARCH AND FOUND THAT THIS IS VERY COMMON. I FOUND THAT ONE OF THE WIRES HAD OVERHEATED AND ACTUALLY BURNED THE FOAM AND COVERING. THERE ARE MANY COMPLAINTS AND PICTURES ON THE INTERNET. I REMOVED MY SEAT AND FOUND THE EXACT SAME PROBLEM. I AM ASTOUNDED THAT NOTHING IS BEING DONE TO STOP THE USE OF THESE DEFECTIVE HEATERS. THIS IS MOST CERTAINLY A VERY SERIOUS FIRE AND BURN HAZARD. *TR

MY VEHICLE STARTED RANDOMLY SHUTTING OFF WHILE DRIVING. LOSS OF POWER TO EVERYTHING BUT THE BRAKES. LUCKILY I WAS ONLY GOING 10-15MPH EACH TIME THIS HAPPENED. WITH THE RECENT RECALL IN GM VEHICLES REGARDING THE IGNITION SWITCH I THOUGHT IT WOULD BE A GOOD IDEA TO SWITCH THIS PART OUT FIRST. FIXED THE PROBLEM IMMEDIATELY. I WOULD LIKE TO BE REIMBURSED MY COST FOR PART AND LABOR. I CAN'T BELIEVE AS MANY KNOWN PROBLEMS THE TRAILBLAZER HAS WITH THIS THAT IT HAS YET TO BE ADDED TO THE RECALL LIST. *JS

WHEN I PULLED INTO DRIVEWAY, I PUT THE VEHICLE IN PARK, AND TURNED THE KEY OFF, AND ACTUALLY PULLED THE KEY OUT OF THE IGNITION SWITCH, WITH THE VEHICLE STILL RUNNING. I BACKED THE CAR UP, WITHOUT THE KEY IN THE IGNITION, WHERE I STARTED SMELLING WIRES BURNING. I CALLED FIRE DEPARTMENT, AND THEY PUT FIRE OUT ON THE FUSE BOX, WITH EVERYTHING MELTED AROUND IT. I HAVE HAD MINOR PROBLEMS WITH THE CAR, I.E. WHEEL BEARING AND BRAKES, BUT, NOTHING LIKE THIS. WHILE MY 14 YEAR OLD DAUGHTER AND I WERE IN THE CAR AT THE TIME, WE DID GET OUT, AND NO ONE WAS HURT. *TR

AFTER DRIVING THE VEHICLE LIKE NORMAL, STOPPED AT A GAS STATION AND WHEN IT WAS RESTARTED, THE FUEL GAUGE, OIL PRESSURE GAUGE, BATTERY GAUGE, TACHOMETER, PRETTY MUCH THE ENTIRE INSTRUMENT PANEL STOPPED WORKING THEN CAME BACK ON. ALSO, INSTEAD OF READING DRIVER LIKE IT NORMALLY DOES, THE PANEL WAS READING UNKNOWN DRIVER. THEN AS WE WERE DRIVING DOWN THE INTERSTATE HOME, THE SPEEDOMETER WENT TO 0 AND WOULD NOT COME BACK UP. AFTER WE GOT HOME, THE NEXT DAY THE PANEL WORKED FINE. THIS HAS OCCURRED NUMEROUS TIME SINCE THE FIRST INCIDENT IN 2011. I HAVE READ MULTIPLE FORUMS AND POSTS ONLINE FROM OTHERS STATING IT IS THE INSTRUMENT PANEL CLUSTER THAT MAY BE THE PROBLEM AND THERE WAS A RECALL ON OTHER CHEVY MAKES BUT NOT THE TRAILBLAZER. THIS IS A VERY SCARY PROBLEM AND SHOULD BE COVERED BY CHEVY DUE TO THE NUMEROUS OTHER TRAILBLAZER OWNERS WITH THE SAME ISSUE. *JB

STARTED THE CAR AND PULLED OUT OF MY DRIVEWAY WAS GOING 0-5 MPH AND THE SPEEDOMETER SHOT UP TO 40. STARTED DRIVING DOWN THE ROAD AND IT STAYED STUCK AT 40, BUT I WAS DOING 30MPH. PULLED INTO THE STORE 2 BLOCKS UP, SHUT THE CAR OFF. WHEN I TURNED IT BACK ON THE CAR WAS REGISTERING 13 MPH AT A DEAD STOP. WENT BACK HOME, CAR SAT OVERNIGHT. STARTED IT FOR WORK IN THE MORNING ON SUNDAY AND IT WAS IDLING AT 8 MPH. STARTED DRIVING TO WORK AND THE SPEEDOMETER WAS REGISTERING 60 MPH, YET I WAS GOING WITH THE FLOW OF TRAFFIC ON A CITY STREET THAT'S SPEED LIMIT WAS 45MPH. SEEMS I NEED TO KEEP TURNING OFF THE CAR AND TURNING IT BACK ON AGAIN IN ORDER FOR THE SPEEDOMETER TO RESET TO A LOWER NUMBER (I.E. 3 OR 8 MPH AT A DEAD STOP, VS. 13 TO 18 MPH AT A DEAD STOP). REVVED THE ENGINE TO SEE WHAT THE RESPONSE WOULD BE, TACHOMETER REGISTERED INCREASE, BUT THE SPEEDOMETER DID NOT BUDGE AT ALL! I WORRY THE DAY IT WILL SAY I AM DOING 40 BUT I AM ACTUALLY DOING 55 AROUND A CURVE. THE CAR IS ABSOLUTELY OFF LIMITS TO MY 17 YEAR OLD NOW. FUNNY THING IS I PREFERRED HER DRIVING THE TRAILBLAZER FOR SAFETY VS. HER LITTLE VW CONVERTIBLE. NOT ANY MORE!! I DO NOT SEE HOW CHEVY CLAIMS THIS IS NOT A SAFETY ISSUE! *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.
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.
