PARKED THE VEHICLE IN A PARKING GARAGE SO I KNOW THE LIGHTS WERE WORKING WHEN WE WENT IN. AS WE WERE LEAVING APPROXIMATELY 3 HOURS LATER, THE LOW BEAMS WOULD NOT COME ON AT ALL. HAD TO RUN HIGH BEAMS; HAD SEVERAL PEOPLE LOOK AT THE FUSES, REPLACED BULBS, ETC. BUT THEY COULD NOT FIND THE PROBLEM. A COUPLE OF WEEKS LATER JUST BEFORE I WAS TAKING IT TO A DEALER TO LOOK AT THE PROBLEM THE LOW BEAMS BEGAN WORKING AGAIN. APPROXIMATELY TWO MONTHS LATER THE EXACT SAME THING HAPPENED ONLY THIS TIME I HEARD A FAINT NOISE FROM THE ENGINE COMPARTMENT AND SMELLED A BURNING (SEEMED ELECTRICAL) AROMA FOR A FEW SECONDS WHEN I REALIZED THE LOW-BEAM LIGHTS WERE NOT WORKING AGAIN. AFTER A WEEK OR SO THE LIGHTS CAME BACK ON AGAIN. *TR

I HAVE BEEN READING MANY OF THESE POST. I CAN'T BELIEVE ALL OF THE THINGS THAT HAVE ALSO HAPPENED TO MY ENVOY. I HAVE HAD MY BACK WINDOW BLOW OUT WHILE DRIVING, THANK GOD THAT BOTH OF MY KIDS THAT WERE IN THE BACK SEAT WERE NOT HURT, THEY WERE JUST SCARED AND STILL ASK IF IT WILL HAPPEN AGAIN. I ALSO RECENTLY JUST HAD TO HAVE A PIECE ON THE GAS LINE FIXED WHICH WAS ALMOST $900.00 MONEY THAT I DIDN'T HAVE AND HAD TO BORROW. I AM STILL PAYING IT BACK. NOW AS FOR LAST NIGHT MY LOW BEAMS ARE NOT WORKING, I BOUGHT NEW BULBS AND THAT DIDN'T WORK, SO IT IS BACK TO THE MECHANIC. OH AND I HAVE A CHECK ENGINE LIGHT THAT GOES ON AND OFF. THEY REALLY NEED TO GET ON ALL OF THESE THINGS. IT WOULD BE NICE TO HAVE THE CAR WORKING THE WAY IT SHOULD BE. I MAY JUST PRINT THESE THINGS UP AND BRING TO THE GMC SHOP AND SEE WHAT THE CAN DO ABOUT IT. I MEAN I REALLY TO LOVE MY SUV BUT THIS IS CRAZY. I AM NOW KIND OF SCARED TO HAVE MY KIDS IN THE CAR. *TR

May 5, 2005
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.

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.
