ERRATIC SPEEDOMETER OPERATION, WE TOOK IT IN TO IN TO BE CHECKED AND THEY SAID IT NEEDED A NEW CLUSTER, ALSO WHILE IT WAS THERE I HAD THEM CHECK THE 4WD SERVICE LIGHT WHICH CAME ON ERRATICALLY AND THEY SAID IT ALSO NEEDED A NEW MODULE. THIS IS FOR A 2004 GMC ENVOY WITH 64,984 MILES. NO EXTENDED WARRANTY SO WE HAD TO PAY FOR THE ALL THE WORK DONE. THE DAY I HAD IT CHECKED OUT THE SERVICE REP DID SAY THERE WERE PROBLEMS WITH A CERTAIN YEAR AND IF WE HAD THE RIGHT YEAR AND VEHICLE AND IF IT WAS UNDER 70,000 MILES THEY WOULD REPLACE IT FOR FREE. WHEN WE CAME BACK A COUPLE DAYS LATER TO HAVE THE WORK DONE HE SAID AFTER I ASKED HIM IT WAS FOR A SILVERADO NOT SURE IF HE SAID 2003 OR 2004 BUT NOT FOR OUR VEHICLE..... I AM VERY DISAPPOINTED AFTER 40 YEARS OF BUYING GM VEHICLES THAT GM DIDN'T TAKE CARE OR HELP TAKE CARE OF THE COST OF THESE PROBLEMS. *TR

APPROXIMATELY 1 1/2 MONTHS AGO MY SPEEDOMETER WENT OUT ON MY GMC 2004 ENVOY. I WENT TO THE DEALERSHIP AND THE PERSON HELPING ME SAID THAT THEY GET ALOT OF REPAIR REQUESTS FOR THE SPEEDOMETERS GOING OUT ON THE GMC'S. SO I STATED IF THIS IS AN OFTEN OCCURRENCE IT APPEARS TO ME THAT IT SHOULD BE A NATIONAL RECALL BEING THAT THIS SEEMS TO OCCUR ALOT. WHEN I GOT HOME I WENT ON LINE TO PULL THE REVIEWS AND TO SEE WHAT OTHERS WERE TALKING ABOUT. THAT IS WHEN I NOTICED THAT A I WAS NOT THE ONLY CUSTOMER WITH THIS PROBLEM. ALSO, WHEN I WENT ONTO MY IPHONE APPLICATION TO SEE IF I COULD FIND ANYTHING THAT COULD ASSIST ME BEING THAT I WAS GOING OUT OF TOWN I FOUND AN APPLICATION AND ONE OF THE PEOPLE POSTING A REVIEW WAS A GUY WHO WAS OUT OF TOWN AND HIS SPEEDOMETER WENT OUT AND HE TOO WAS ABLE TO FIND THE SAME SPEEDOMETER THAT I HAD TO USE IN ORDER FOR HIM TO GET BACK TO WHERE HE WAS GOING. AS A CUSTOMER I FEEL THAT IF THIS IS A PROBLEM THAT IS OCCURRING AT THE 35,000-45,000 MARK OF THESE VEHICLES THEN IT SHOULD BE THE RESPONSIBILITY OF THE MANUFACTURER TO MAKE GOOD ON THIS MALFUNCTION. MY CAR IS NOT QUITE 5 YEARS AND I ONLY HAVE APPROXIMATELY 42,500 MILES ON MY TRUCK. *TR

I TRADED MY 2005 FORD FOCUS 26410 MILES TO WADE RAULERSON GMC ON OCTOBER 3, 2007 WROTE TWO CHECKS IN THE AMOUNT OF 500.00 EACH THAT THEY HELD FOR FOUR WEEKS FOR A DOWN PAYMENT. WE LOOKED AT A 2004 GMC ENVOY WITH 65,000 MILES THE SALESMAN QUOTED US A PRICE OF 17,000 SO WE DID THE PAPER WORK THE FIRST TIME ON THE 16TH WE WERE CALLED IN AGAIN AND TOLD WE HAD TO SIGN MORE DOCUMENTS THIS TIME THE PRICE OF THE ENVOY ROSE TO 21698.35, I ASKED ABOUT MY 05 FOCUS WAS TOLD IT SOLD THE NEXT DAY AND WE HAD TO HAVE GAP PROTECTION. PAYOFF ON MY CAR WAS 12,502.95 AND IT LOOKED AS IF THEY WERE GIVING ME 14900.00 BUT RAISED THE PRICE OF THE TRUCK BY 4000.00. BAD DEAL TO BEGIN WITH. THE PROBLEMS BEGAN. I HAD TO RETURN IT AT THE END OF THE MONTH IN OCTOBER 2007 TO HAVE THE HEADLIGHTS, SEATBELT, AND MOTOR IN THE WINDOW REPLACED, AND DIAGNOSED TO FIND WHY THE SERVICE ENGINE LIGHT WILL NOT GO OUT. TWO WEEKS LATER STRANDED AT THE DAYCARE I HAD TO BUY A NEW BATTERY. ON 05/05/2008 THE CONDITIONER WENT OUT. I PAID THE DEALERSHIP OVER 100.00 TO TELL ME IT WOULD BE AN ADDITIONAL 600.00 PLUS DOLLARS TO REPAIR THE MODE ACTUATOR DOOR MOTOR. OCTOBER 17, 2008 I SPENT 375.02 TO HAVE BOTH THE SHIFT CONTROL CABLE AND GEAR SHIFT LEVER REMOVED AND REPLACED. THANK GOD I WAS ACTUALLY ON A PARKING LOT WHEN THE CABLE BROKE AND NOT IN TRAFFIC. CONTACTING WADE RAULERSON GMC HAS BEEN USELESS I HAVE PRACTICALLY BEEN TOLD YOU BOUGHT THE "LEMON" AS-IS NOW IT'S YOUR TROUBLES! THERE SHOULD BE A LAW AGAINST THIS TYPE OF BUSINESS AND NOT JUST FOR NEW CARS. NOW NO-ONE WILL TOUCH IT BECAUSE OF THE PROBLEMS IT IS HAVING AND THE LARGE AMOUNT THAT'S NOW OWED. EVERY TIME THE VIN IS PULLED I GET PUSHED OUT OF THE DOOR FASTER THAN I CAN BLINK. BTW THE SERVICE ENGINE LIGHT IS STILL ON AND HAS BEEN SINCE I LEFT THE DEALERSHIP. I?M TIRED OF HONEST HARD-WORKING PEOPLE BEING RAKED OVER THE COALS BY UNSCRUPULOUS DEALERS WHILE THEY GET PROTECTED BY THE "AS-IS" RULE THEN LAUGH ALL THE WAY TO THE BANK. *TR
DURING NORMAL DRIVING CONDITIONS AND WITH NO WARNING BOTH THE SPEEDOMETER AND TACHOMETER TOPPED OUT AND HAVE NOT WORKED SINCE. *TR
SPEEDOMETER STOPPED WORKING PROPERLY. $500 TO REPLACE. GM WILL NOT HELP, EVEN THOUGH THEY ARE AWARE OF THE DEFECTIVE UNITS THAT ARE ON THE STREETS. THEY HAVE RECALL ON PICKUP TRUCKS FOR SAME PROBLEM. *TR
Official recalls
104V527000 · Exterior Lighting:brake Lights
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.

4RQ17002 · 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.
