I HAVE HAD TROUBLE WITH THE HEADLIGHTS DIMMING WHILE DRIVING SINCE THE BEGINNING, THE DEALERSHIP HAS SEVERAL TIMES WORKED ON THE PROBLEM, WHICH I THINK HAS CLEARED UP..SO FAR. NOW MY SPEEDOMETER HAS STARTED MESSING UP, IT SAYS I AM GOING 50 WHILE PARKED AND 120 WHILE DRIVING. I ONLY DRIVE SHORT DISTANCES AND MOSTLY INTO AND BACK FROM TOWN 6 MILE ONE WAY. I HAVE 50,969 MILES ON MY 2004 VEHICLE, I KEEP ITS CHECKUPS AND OIL CHANGES REGULARLY: DEALERSHIP HAS RECORDS. I FEEL THIS VEHICLE HAS HAD ELECTRICAL ISSUES FROM DAY ONE, I SEE TURN SIGNAL AND BRAKELIGHT ISSUES IN RECALL SO I DON'T BELIEVE I AM WRONG ABOUT THIS. THEY WANT TO CHARGE ME OVER $400 TO CHANGE THE "CLUSTER" AS THE ECONOMY GOES, I TOO CANNOT AFFORD THIS KIND OF CHARGES ON AN ITEM THAT SHOULD NOT HAVE ISSUES. ESPECIALLY WHEN I TAKE GOOD CARE OF IT AND REALLY HAS LOW MILEAGE AND WEAR AND TEAR (PERFECT CONDITION). *TR

WHICH BECOMES A HAZARD BECAUSE I AM UNAWARE OF HOW FAST OR SLOW I AM GOING. MY FAMILY AS WELL AS MYSELF ARE IN SERIOUS DANGER OF GETTING INTO AN ACCIDENT BECAUSE OF THIS PROBLEM. IT WILL NOT START WORKING AGAIN UNTIL THE NEXT DAY. IT HAS BEEN HAPPENING QUICKER AND QUICKER AS THE PROBLEM PERSISTS. I AM ALSO NOTICING A HOT SMELL WHEN THE SPEEDOMETER STOPS WORKING. BUICK REFUSES TO HELP WITH THIS PROBLEM EVEN THOUGH I HAVE REPORTED THIS BEFORE MY EXTENDED WARRANTY EXPIRED. *TR

WHILE DRIVING ON THE FREEWAY I NOTICED THAT THE SPEEDOMETER READING WAS TOO HIGH AS I WAS CHANGING LANES TO EXIT DURING EVENING RUSH HOUR. AFTER EXITING AND STOPPING FOR A TRAFFIC LIGHT, MY SPEEDOMETER WAS SHOWING 55MPH. AS I CONTINUED ON THE SERVICE DRIVE I OBSERVED 75 AND 85MPH IN A 35MPH ZONE! VERY DISTRACTING WHEN DRIVING NEXT TO A 70MPH FREEWAY. I NOT GOING THAT FAST I'M CRAWLING. WHEN I TURNED ON TO MY STREET I WAS STILL OBSERVING THE SPEED AT 65MPH AND NEARLY RAN OVER MY NEIGHBOR WHO WAS PUTTING HIS TRASH OUT AT THE CURB. ALMOST PASSED MY DRIVEWAY AND DROVE OVER A BIT OF THE OTHER NEIGHBORS GRASS. I COULD NOT BELIEVE A 4-YR OLD VEHICLE WITH 64000 MILES HAD A BAD SPEEDOMETER. SO I CHANGED THE INSTRUMENT CLUSTER FUSE AND THE SPEEDOMETER STARTED TO WORK AGAIN AND SEEMED TO BE ACCURATE. ON MY WAY HOME FROM WORK IT AGAIN SHOT UP TO 120+MPH AND THAT IS WHERE IT STAYED. CHANGED THE FUSE AGAIN SEEMED TO WORK FOR A DAY AND SHOT UP AGAIN TO 120+ MPH. DROVE IT TO THE DEALERSHIP TO HAVE TO REPAIRED AND THEY SAY IT IS THE INSTRUMENT CLUSTER THAT IS BAD AND IT WILL COST $450.00. NO LONGER UNDER WARRANTY AND I CANNOT REPAIR AT THIS TIME. DEALERSHIP SERVICE SAYS THEY HAVE NOT HEARD OF THIS HAPPENING AT ALL. FOR MY MONEY THEY WILL ONLY WARRANTY IT FOR 1YR/12000 MILES. I HAVE ALWAYS BELIEVED BUY AMERICAN BUT RIGHT NOW I AM TRULY DISAPPOINTED. *TR

3RQ17002 · 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.
