I PURCHASED A NEW 2004 ENVOY XUV IN 7/2004. AFTER ABOUT 3 MONTHS OF OWNERSHIP THE STEERING WHEEL STARTED TO MAKE A SQUEAKING NOISE WHEN TURNING OR BEING IN PARK AND TURNING THE WHEEL. WHEN I BROUGHT IN THE XUV FOR AN OIL CHANGE I TOLD THE DEALER ABOUT THE SQUEAK BUT THEY WERE UNABLE TO DUPLICATE THE NOISE THAT DAY. HOWEVER, THE NOISE WAS STILL THERE AND AS THE TIME CAME CLOSER TO THE NEXT OIL CHANGE THE NOISE WAS GETTING LOUDER. IT WAS KIND OF A SCRAPING SOUND. THE DEALER DID HEAR THAT SOUND THAT WAS DESCRIBED AND LUBRICATED SOMETHING IN THE STEERING WHEEL. THE NOISE FADED BUT WAS BACK WITHIN THE NEXT COUPLE OF DAYS. WELL, TODAY I BROUGHT IN THE XUV FOR IT'S SCHEDULED OIL CHANGE AND COMPLAINED ABOUT THE NOISE. THE ANSWER THE GMC DEALERSHIP GAVE ME WAS THAT THIS IS A COMMON DEFECT IN THE ENVOYS AND YUKON AND THERE WAS NOTHING THEY CAN DO TO FIX IT. CHANGING THE STEERING SHAFT WOULD NOT FIX IT AND LUBRICATING IT WON'T WORK EITHER. THE NOISE COMING FROM THE STEERING WHEEL IS LIKE A WINDOW BEING CLEANED WITH A SQUEEGEE. SO, AS OF TODAY...STILL NO RESOLUTION TO THE PROBLEM. *JB
DT: CONTACT STATED THE ACCELERATOR PEDAL HAD TO BE REPLACED. WHILE ACCELERATING TO MAKE A LEFT-HAND TURN THE ACCELERATOR WOULD NOT TAKE. THE SERVICE DEALER REPLACED THE ACCELERATOR PEDAL. THE REPAIR WAS COVERED UNDER THE WARRANTY OF THE VEHICLE. THIS REMEDIED THE PROBLEM. *AK UPDATED 11/29/05. *JB

DT: THE CONSUMER COMPLAINED ABOUT A POWER STEERING PROBLEMS. THERE WAS A CONSTANT SQUEAK IN THE STEERING EVEN WHILE THE VEHICLE WAS PARKED. SHE SAID THERE WAS A POPPING NOISE WHILE TURNING RIGHT OR LEFT. THE CONSUMER ALSO HEARD THE POPPING NOISE WHILE GOING OVER SPEED BUMPS. THE SQUEAKING NOISE BEGAN AS SOON AS THE VEHICLE STARTED. THE SERVICE DEALER REPLACED THE POWER STEERING BELT, POWER STEERING GEAR, A LINK AND BUSHING, AND THE DRIVE BELT. ALSO, THE DEALER ADJUSTED THE POWER STEERING PULLEY. THIS DID NOT REMEDY THE PROBLEM, SO THEY REPLACED THE ENTIRE POWER STEERING PUMP. HOWEVER, THE PROBLEM RECURRED. THE DEALER THOUGHT IT MAY HAVE BEEN SOMETHING IN THE FRONT SUSPENSION, SO THEY REPLACED TWO STABILIZER LINKS. THIS STILL DID NOT REMEDY THE PROBLEM. *AK UPDATED 11/29/05. *JB

MY GMC ENVOY IS NOT A YEAR OLD....BOUGHT MAY 2004. AND SOMETIMES THE BRAKES DO NOT WORK. AS I AM APPROACHING THE TRAFFIC STOP AND I STEP ON THE BRAKES..MY VEHICLE IS NOT STOPPING UNTIL I GET VERY CLOSE TO TRAFFIC. I DO NOT FEEL SAFE IN MY VEHICLE BUT ITS MY ONLY LIABLE TRANSPORTATION. I TRIED TAKING IT TO MY DEALER, BUT THEY CAN NOT FIND ANYTHING WRONG. THEY JUST ADVISED ME THAT THE ABS IS DOING IT'S JOB. I THINK THAT IF THE ABS IS DOING ITS JOB, THE VEHICLE WOULD STOP RIGHT AWAY, NOT WENT I'M NEAR KILLING MYSELF AND OTHERS!!! MY DEALER SAYS THAT I SHOULD TRADE IT IN, BUT I OWE ALOT ON THIS VEHICLE ALREADY!!! WHAT ELSE CAN I DO? I HAD 3 INCIDENTS ALREADY. THE LAST INCIDENT DATE IS RECORDED BELOW. I ALSO HAD OTHER THINGS HAPPEN TO MY VEHICLE AS WELL, SUCH AS TROTTLING NOISE IN THE ENGINE AND ONCE THE VEHICLE COMPLETELY STOP AND THERE WAS MAJOR NOISE FROM THE ENGINE. THE CHECK ENGINE MESSAGE ALSO LIGHTS UP EVERY ONE IN A WHILE. I FEEL THAT MY DEALER WHICH IS CALLED PERFORMANCE OF FARMINGTON NEW MEXICO, ARE WAITING UNTIL MY WARRANTY ENDS OR UNTIL I HAVE A VEHICLE ACCIDENT. I NEED SOME HELP.

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.

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.
