NO PREVIOUS PROBLEMS WITH PANEL. PROBLEM OCCURS FREQUENTLY. TACHOMETER QUIT WORKING CORRECTLY...GOES COMPLETELY TO OPPOSITE END OF GAUGE. TOOK DAYS BEFORE IT WENT BACK TO NORMAL LOCATION. SPEEDOMETER DOES NOT WORK CORRECTLY...CONTINUES TO CLIMB TO HIGHER END OF GAUGE....READS ABOVE 30 EVEN WHEN STANDING STILL. GOES DOWN AFTER REPEATEDLY SHUTTING OFF AND RESTARTING ENGINE. WHIRRING SOUND MADE WHEN STARTING OR STOPPING ENGINE. CONTACTED CHEVY DEALER REPAIR SHOP, THEY ARE FULLY AWARE OF SITUATION, ADVISED IT WILL GET WORSE AND WILL EVENTUALLY STOP WORKING AT ALL. NO PARTS ARE SERVICEABLE, NEEDS TO BE SENT OUT FOR REPAIR, COULD TAKE ANYWHERE FROM A DAY TO A WEEK OR MORE DEPENDING ON THE PARTS NEEDED. PLUS THERE IS THE ADDITIONAL COST OF HAVING IT READ BY THE COMPUTER FOR THE CORRECT PART(S). MY CAR WILL BE INOPERABLE SOON ACCORDING TO DEALER, UNSAFE TO DRIVE, SITUATION NEEDS IMMEDIATE FIX. *TR

I OWN A 2004 CHEVROLET TRAILBLAZER NORTH FACE/EXT. THE SPEEDOMETER HAS BEEN GIVING ME PROBLEMS FOR SOME TIME. AT FIRST IT WOULD MALFUNCTION FROM TIME TO TIME. NOW THE FUEL GAUGE HAS STOPPED ALL TOGETHER. WHEN I STARTED INVESTIGATING THIS PROBLEM I FOUND OUT THAT IT IS A COMMON PROBLEM WITH THIS MAKE AND MODEL VEHICLE. I ALSO FOUND OUT THAT CHEVROLET HAS ANOTHER VEHICLE, "CHEVY TAHOE", THAT HAS HAD THE SAME PROBLEM. WHY THERE IS A RECALL TO FIX THE TAHOE AND NOT THE TRAILBLAZER EXT. IS VERY INTERESTING TO ME. I HAVE GONE AS FAR AS TO TAKE A LOOK AT THE TAHOE INSTRUMENT CLUSTER AND SAW THAT THEY ARE VERY ALIKE. THE VEHICLE RECALL TO REPLACE THE INSTRUMENT CLUSTER ON THESE VEHICLES SHOULD BE SENT OUT ASAP. IF YOU TAKE A LOOK AT THE COMPLAINTS ON THE INTERNET YOU WILL SEE THAT THIS IS A PROBLEM THAT MANY TRAILBLAZER OWNERS SEEM TO BE HAVING. YOU WILL ALSO SEE THAT THE TAHOE COMPLAINTS, "FOR WHICH THERE IS A RECALL", ARE IDENTICAL. THANK YOU; PATRICK *TR

SEVERAL TIMES THAT I'VE BEEN DRIVING THE TRAILBLAZER, THE SPEEDOMETER GOES CRAZY AND SAYS THAT WE ARE TRAVELING AT A MUCH HIGHER RATE OF SPEED THAN WE ARE. LIKE IF IM GOING APPROX 70MPH, IT STATES WE ARE GOING ABOUT 110MPH! THIS IS DEFINITELY A SAFETY ISSUE! AND IT HAS NEVER BEEN A RECALL? *TR

I OWN A 2004 TRAILBLAZER EXT AND A COUPLE OF MONTHS AGO THE RPM GAUGE STOPPED FUNCTIONING AND DOESN'T EVEN REGISTER. LESS THAN A MONTH LATER THE SPEEDOMETER STARTED MALFUNCTIONING AND MANY TIMES DOESN'T EVEN REGISTER A SPEED WHILE DRIVING FOR SEVERAL HOURS. THIS HAS BEEN A DAILY OCCURRENCE EVERY TIME MY WIFE AND FAMILY GET IN THE VEHICLE. THIS IS A SERIOUS SAFETY HAZARD FOR MY FAMILY AND FOR ANYONE ELSE WE MAY PASS ON THE ROAD. I KNOW FROM READING MULTIPLE OTHER COMPLAINTS ACROSS THE INTERNET THAT THIS IS NOT AN ISOLATED ISSUE AND THAT GM HAS ALREADY RECALLED THE CONSOLE CLUSTER ON SEVERAL OTHER MODELS HAVING THE SAME OR SIMILAR ISSUES. WHEN ARE THEY GOING TO BE HELD RESPONSIBLE FOR ALSO RECALLING THE SAME PROBLEM ON THIS VEHICLE MAKE? *TR

ONE DAY I WAS DRIVING DOWN THE ROAD AT ABOUT 40 MPH, BUT WHEN I LOOKED AT THE SPEEDOMETER IT WAS READING 90. FOR ABOUT A MONTH THE SPEEDOMETER NEVER REACHED ZERO AND PERFORMED NORMALLY. ONE DAY IT FINALLY DID REACH ZERO AND ACTED PROPERLY FOR ABOUT A WEEK, THEN BEGAN ACTING UP AGAIN. SINCE THEN, IT HAS GOTTEN STUCK POINTED DOWN AND DOES NOT MOVE AT ALL. ALSO, MY RPM BEGAN ACTING UP AS WELL. NOW IT STARTS BELOW ZERO AND ONLY MOVES OCCASIONALLY. THIS IS A MAJOR CONCERN FOR ME BECAUSE I CAN HANDLE NOT KNOWING THE EXACT SPEED OF MY VEHICLE, BUT NOT KNOWING THE RPM ALSO MAKES IT DIFFICULT BECAUSE I HAVE NO REAL WAY TO DETERMINE MY SPEED. THIS IS A DANGEROUS ISSUE THAT MUST BE ADDRESSED. I HAVE A FRIEND WITH A TRAILBLAZER LIKE MINE AND HE HAS A SIMILAR PROBLEM. SPEEDOMETER DOESN'T WORK. ONLINE I'VE ALSO FOUND HUNDREDS OF PEOPLE WHO HAVE THIS SAME PROBLEM. GM MUST CORRECT THIS ELECTRICAL GLITCH! *TR

SPEEDOMETER HAS COMPLETELY STOPPED WORKING. STARTED OUT INTERMITTENT. *TR
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.

RQ17002 · 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.
