I PURCHASED THIS VEHICLE 10 MONTHS AGO AND HAVE TO REPLACE THE HEADLIGHTS 9 SEPERATE TIMES NOT INCLUDING THE BRAKE LIGHTS 5 TIMES. AFTER THE 3RD TIME THE MAN AT THE AUTO PARTS STORE STATED THIS IS A KNOWN PROBLEM WITH GMC> THE LIGHTS GET TOO HOT AND BURN UP THE BULB AND THE CONNECTORS. I HAVE HAD 2 BUY NOW 4 RABBITS CONNECTORS AND THEY MAKE THE BULB LAST A LITTLE LONGER BUT THE EXSPENSE IS SAD. IF THIS IS A KNOWN PROBLEM AND IT IS POSTED ALL OVER THE INTERENT FROM CUSTOMERS WITH THE SAME ISSUES WHY HAS NOT RECALL BEEM PLACED FOR THESE LIGHTS. IF IT IS HEATING HOT ENOUGH TO MELT A CONNECTOR THAT IS A FIRE HAZARD AND NEEDS TO BE RECALLED. NOW MY SPEEDOMETER STOPED WORKING AND TO MY SURPRISE I WASS ADVISED THIS ALSO A COMMON GMC PROBLEM WITH THE CLUSTER REPAIR BEING REQUIRED TO FIX IT.

THE SPEEDOMETER ON MY 2004 ENVOY XL BEGAN ACTING ERRATICALLY ( GOING FROM 0 TO 120 ) A EARLIER 2011 AND CONTINUES. THE GAS GAUGE DOES NOT REGISTER PROPERLY EITHER. THE DEALER WANTED TO CHANGE MY SPEEDOMETER FIRST TO SEE IF THIS WOULD FIX BOTH PROBLEMS (OVER $600.00 IN COST) AND IF THAT DIDN'T FIX IT, THEN THEY WOULD HAVE TO CHANGE A MODULE IN THE FUEL TANK (ANOTHER $600.00 IN COST). MY RESEARCH ON THE INTERNET INDICATES THIS IS A FAULTY PART AND NEEDS TO BE RECALL. I'VE READ DIFFERENT MAKES OF GMC AND MILEAGE HAVE COMPLAINED ABOUT THIS ISSUE. *TR

THE CLUSTER INSTRUMENT PANEL FLASHES ON AND OFF GUAGES ARE ALL INCORRECT FROM TIME TO TIME AND DO NOT WORK SOME TIMES. *TT
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.

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.
BY LETTER DATED APRIL 29, 2005, GM NOTIFIED THE AGENCY THAT IT IS CONDUCTING ASAFETY RECALL ( NHTSA RECALL NO. 05V198 ) INVOLVING CERTAIN MODEL YEARS (MY) 2003-2004 ISUZU ASCENDER, CHEVROLET TRAILBLAZER, GMC ENVOY, OLDSMOBILE BRAVADA AND MY 2004 BUICK RAINER VEHICLES.THE RECALL APPLIES TO VEHICLES BUILT FROM APRIL 2003 THROUGH NOVEMBER 2003 FOR A TOTAL VEHICLE POPULATION OF 286,478.GM REPORTS THE DIRECTIONAL/HAZARD SIGNALS FAILURE IS DUE TO STICKING CONTACTS ON ROUTING RELAYS IN THE FLASHER MODULE.GM WILL REPLACE THE FLASHER MODULE ON ALL INVOLVED VEHICLES.BASED ON GM'S SAFETY RECALL ACTION, THIS INVESTIGATION IS CLOSED.
