THE TRANSMISSION STARTED TO SLIP, NOTICED IT STARTING TO HAVE ISSUES GETTING UP TO PROPER SPEED WITHOUT SLIPPING AND TRYING TO STALL, AND WAS TOLD BY PREVIOUS OWNER WHOM I'M PURCHASING IT FROM THAT THERE IS A POSSIBLE ISSUE WITH THE TRANSFER CASE AS WELL, AS IT ENGAGES IT'S 4 WHEEL DRIVE WITHOUT ME TOUCHING IT, TRIED TO SERVICE THE TRANSMISSION AND PUT FRESH FLUID AND A NEW FILTER IN TO SEE IF IT WOULD HELP AND NOW IT CAN ONLY GO AS FAST AS 40 TO 55 BEFORE IT STARTS TO SLIP PRETTY BAD. I HAVE A BABY ON THE WAY DUE IN THE NEXT COUPLE WEEKS AND WITH IT SLIPPING AND DROPPING SPEED IT CAN CAUSE ME TO END UP GETTING HIT AND I DON'T WANT TO PUT MINE, MY CHILD, OR ANY OF MY OTHER PASSENGERS IN DANGER.

BOUGHT "CERTIFIED USED" ENVOY IN OCTOBER OF 07. TRANSMISSION COMPLETELY STOPPED AT 57K MILES 3 MONTHS AFTER PURCHASE. CHECK ENGINE LIGHT COMES ON AND OFF EVERY COUPLE DAYS(HAVE VIDEO, BUT SANDY SANSING OF PENSACOLA FLORIDA SAYS THERE NOTHING WRONG) VEHICLE JERKS AT STOPS AND STARTS. AFTER 3 TRIPS TO DEALERSHIP W/ "NOTHING WRONG" THEY FINALLY DECIDED THAT A O2 SENSOR WAS BAD AT 71K. ENVOY HAD BEEN BACK IN THE SHOP AT A COST OF 80.00 BUCKS TWICE SINCE THEN BECAUSE OF THE "CHECK ENGINE" LIGHT AND THE BRAKES ARE FAILING, THE "ABS BRAKE" LIGHT DOESN'T COME ON SO THEY SAY IT CANT BE THE BRAKES. WHEN TRYING TO STOP THE BRAKES STOP WORKING AND A SECOND LATER THEY WILL CATCH AND BEGIN TO STOP VEHICLE, AS IF THE BRAKE SYSTEM IS OBSTRUCTED AND SKIPS A FEW TIMES. THE CHECK ENGINE LIGHT FLASHES FOR THOSE FEW SECONDS BUT DOESN'T STAY ON LONG AND THEY SAY IT ISN'T THROWING ANY CODES. PROBLEM DOESN'T HAPPEN EVERYDAY SO THE DEALERSHIP HAS SAID ITS A UNFOUNDED PROBLEM. THE THERMOSTATS ASSEMBLY WITH OTHER PARTS HAVE BEEN REPLACED. HAVE ALL RECEIPTS AND DATES THAT I'VE TAKEN THIS POS INTO THE DEALERSHIP. I WILL NEVER BUY ANOTHER GMC VEHICLE. I HAVE A 10 YEAR OLD PICKUP TRUCK ALSO AND HAS ONLY BEEN IN THE SHOP ONCE. THERE'S NO EXCUSE THAT WE ARE DRIVING THESE (EXPENSIVE) UNSAFE VEHICLES!! *TR

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.
