MY 2004 GMC ENVOY HAS DEVELOPED AN ERRATIC SPEEDOMETER. THE SPEEDOMETER REFLECTS INACCURATE SPEEDS CAUSING AN UNSAFE DRIVING CONDITION. I CONTACTED MY LOCAL GMC DEALER WHO RESEARCHED TO FIND NO RECALL CONCERNING THIS PROBLEM I THEN SUBMITTED MY COMPLAINT TO THE BBB HOTLINE AND WAS REBUFFED THEIR ALSO. I HAVE CONSEQUENTLY DONE ADDITIONAL RESEARCH AND HAVE FOUND THAT GM HAS ISSUED A SPECIAL COVERAGE ADJUSTMENT BULLETIN FOR 2003-2004 CADILLAC ESCALADE, CHEVROLET AVALANCHE, SILVERADO, SUBURBAN AND TAHOE, GMC SIERRA AND YUKONS. THE SPEEDOMETER UNIT IN THESE MODELS ARE VERY SIMILAR IN BOTH APPEARANCE AND ARE MANUFACTURED BY THE SAME SUPPLIER GM USES. THE ADJUST BULLETIN IS #07187 DATED SEPTEMBER 28,2007 AND COVERS THE CONDITION FOR A PERIOD OF 7 YEARS OR 70,000 MILES REGARDLESS OF OWNERSHIP. AFTER VISITING MANY GMC AND CHEVROLET CHAT ROOMS IT IS READILY APPARENT THAT THIS PROBLEM IS VERY COMMON AND WILL EVENTUALLY RESULT IN A FATAL ACCIDENT. I AM REQUESTING THAT THE NHTSA FORMALLY INVESTIGATE THIS PROBLEM BEFORE THIS HAPPENS. *TR

PROBLEM STARTED OUT AS ERRATIC READING WITH SPEEDOMETER. AFTER APPROX. 5 DAYS SPEEDO FINALLY WOULDN'T REGISTER AT ALL TOOK VEHICLE TO AUTHORIZED DEALER TO BE REPAIRED - $555.00 CHARGE TO REPLACE INSTRUMENT PANEL AND REPROGRAM. CALLED GM FOR FINANCIAL HELP AS I NOTICED THERE WERE ALOT OF FAILURES WITH GMC SUV'S AND PICK-UP TRUCKS. GM WOULD NOT ACKNOWLEDGE THERE WAS A PROBLEM WHICH I FEEL IS TOTALLY DISINGENUOUS. SPEEDOMETER IS NECESSARY TO BE WORKING AS A SAFETY ISSUE. BECAUSE I WAS OUT OF STATE AT THE TIME OF PART BREAKDOWN I FELT I HAD NO CHOICE BUT TO HAVE PROBLEM FIXED BEFORE MY RETURN TRIP HOME (1250 MILES). JUDGING HOW MANY OTHER ENVOYS HAVE HAD SAME PROBLEM, I FEEL GM IS DODGING THEIR RESPONSIBILITY I NOTICED THAT THERE HAS BEEN CLASS-ACTIONS AGAINST THEM FOR THE SAME PROBLEM. *TR

THIS PROBLEM OCCURS FREQUENTLY, NOT EVERYDAY BUT I WOULD SAY ATLEAST ONCE EVERY 2 WEEKS. I BELIEVE THERE COULD BE GRAVE CONSEQUENCES., YOU HAVE ABSOLUTELY NO IDEA HOW FAST OR SLOW YOU ARE ACTUALLY GOING, ESPECIALLY IF THERE ARE NO CARS TRAVELING THE SAME DIRECTION AS YOU. I WILL ATTEMPT TO REPAIR THIS ITEM MYSELF SINCE THE DEALER SAYS IT CAN COST $300-$700 TO FIX. *TR

I BEGAN EXPERIENCING PROBLEMS WITH THE INSTRUMENT PANEL ON MY 2004 GMC ENVOY A FEW MONTHS AGO. THE ENTIRE PANEL WOULD GO OUT AND ALL THE GAUGES BOTTOMED OUT. I COULD NOT TELL MY SPEED, GAS LEVEL, RPMS, ETC. THE PANEL WOULD STAY OUT FOR A FEW DAYS THEN RETURN TO NORMAL. ALSO ON OCCASION THE SPEEDOMETER WOULD STICK AT 60 MPH AND ONLY CORRECT ITSELF IF I PULLED OVER AND TURNED THE TRUCK OFF THEN BACK ON. FINALLY, ABOUT TWO WEEKS AGO THE ENTIRE INSTRUMENT PANEL WENT OUT AND HAS NEVER COME BACK ON. I HAVE DROPPED IT OFF AT THE DEALERSHIP FOR SERVICE AND AM AWAITING THEIR RESPONSE. THIS PROBLEM HAS CAUSED ME TO RUN OUT OF GAS TWICE BECAUSE I WAS UNABLE TO JUDGE MY FUEL LEVEL. LUCKILY BOTH TIMES I WAS IN AN AREA WITH EASY ACCESS TO THE SHOULDER OF THE ROAD. I CURRENTLY HAVE APPROXIMATELY 55,000 MILES ON MY TRUCK. (I CAN'T BE SURE OF THIS, HOWEVER, SINCE THE ODOMETER IS A PART OF THE PANEL THAT IS OUT.) THIS IS A SERIOUS AND, ACCORDING TO MY RESEARCH, RECURRING PROBLEM THE GMC SHOULD BE FORCED TO CORRECT AND PAY FOR. *TR
ON CERTAIN TRUCKS AND SPORT UTILITY VEHICLES, THE DRIVER WISHING TO SIGNAL A TURN BY MOVING THE DIRECTIONAL SIGNAL LEVER, (UP OR DOWN) MAY CAUSE THE FRONT MARKER/TURN LIGHTS AND REAR TURN LIGHTS TO FLASH IN A MANNER SIMILAR TO HAZARD WARNING, RATHER THAN FLASHING ON THE DESIRED SIDE ONLY.
Consequence & remedy
Consequence: THE DRIVER MAY NOT BE ABLE TO CLEARLY SIGNAL THEIR INTENTIONS TO TURN, CHANGE TRAVEL LANES, OR POTENTIALLY WARN OTHERS OF AN IMPAIRED VEHICLE OPERATING CONDITION INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE SUSPECT FLASHER MODULES WITH A NEW FLASHER MODULE DESIGNED WITH SEALED RELAYS AND MORE DURABLE CONTACT MATERIAL INSIDE OF THE RELAYS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 4, 2005. ISUZU BEGAN MAILING OWNER LETTERS ON AUGUST 4, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, ISUZU AT 1-800-255-6727, BUICK AT 1-866-608-8080, AND OLDSMOBILE AT 1-800-630-6537.

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.
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.
