I WAS DRIVING ONE MORNING AND NOTICED THAT MY SPEED REGISTERED 80MILES WHEN I HAD JUST PULLED OFF. I CUT THE CAR OFF AND THEN STARTING BACK DRIVING AND IT THEN SAID I WAS GOING 120. I TOOK MY CAR IN AND THEY TOLD ME THAT MY CAR WAS NOT UNDER WARRANTY FOR THIS REPAIR, AND IT WOULD COST ME $575. TO GET IT FIXED. I ASKED FOR THE MAIN NUMBER TO BUICK AND CALLED THEM, THEY SAID THAT MY CAR DID NOT FALL IN THE EXTENDED WARRANTY CATEGORY AND THEY DID NOT HAVE ENOUGH COMPLAINTS TO HAVE THIS AS A RECALL. I ALSO TOLD THEM THAT THIS IS A SAFETY HAZARD AND THAT I SHOULD NOT HAVE TO PAY OUT OF POCKET FOR A MANUFACTURER DEFECT AND THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM ON THIS PARTICULAR VEHICLE. I COULD BE SITTING WITH THE CAR IDLE AND THE SPEEDOMETER READS 120, EVEN WHEN I MADE THE APPT. TO HAVE IT CHECKED OUT THE SERVICE GUY SAID THAT QUITE A FEW PEOPLE HAVE BEEN IN WITH THAT PROBLEM. *TR

I STOPPED AND SWITCHED THE CAR OFF AND THOUGHT IT WOULD RESET THE GAUGES BUT IT ONLY WENT TO 65MPH. AS I BEGAN DRIVING AGAIN IT STARTED REGISTERING 120MPH.

I HAVE NO CLUE WHAT SPEED I AM TRAVELING WHILE DRIVING. I WENT TO MY DEALER AND HE SAID I WOULD HAVE TO PAY FOR IT TO BE FIXED. I DID NOT HAVE IT FIXED. *TR

MY SPEEDOMETER STARTED TO STICK AT 60 MPH WHEN DRIVING SLOWLY AFTER EXITING OFF OF THE FREEWAY AT NIGHT. I THEN PROCEEDED ON MY WAY HOME IN A 30MPH ZONE AND THEN THE SPEEDOMETER WAS PEGGED OUT AT OVER 120MPH. FROM THEN ON SOMETIMES THE NEEDLE ON THE GAUGE ALMOST GOES TO ZERO UNTIL YOU START TO DRIVE THE VEHICLE, AND THEN IT PEG'S OUT AGAIN. CONSEQUENTLY MY WIFE AND I DO NOT KNOW HOW FAST WE ARE GOING WHICH IS A MAJOR SAFETY ISSUE ESPECIALLY AT FREEWAY SPEEDS OR DRIVING THROUGH THE NEIGHBORHOOD WHERE CHILDREN PLAY. I HAVE NOT PAYED TO REPLACE A 500 HUNDRED DOLLAR ITEM. *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.
EA07009 · Fuel Pump Module Leaks Gasoline
Opened Jul 10, 2007 · Closed Aug 28, 2008
Status: closed (inferred from source dates) · Fuel System, Gasoline:delivery:fuel Pump
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.
