2006 GMC Envoy Xl

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.

On August 15, 2012 General Motors (GM) announced a regional recall action (12V-406) involving model year (MY) 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender and MY2005-2007 SAAB 9-7x vehicles originally sold or currently registered in the salt belt states of Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. The recall remedy requires the inspection and repair or replacement of the master power window switch, which GM refers to as a driver door module (DDM). At the same time, GM implemented a special coverage program to replace failed DDMs for vehicles registered outside of these states. ODI was not satisfied with GM's exclusion of non-salt belt vehicles and continued its investigation. On June 13, 2013, GM submitted a related recall notification (13V-248) to reclassify the initial special coverage program into a safety recall for vehicles that were not previously repaired under special coverage.The Office of Defects Investigation (ODI) opened Engineering Analysis EA12-004 on June 11, 2012 to further investigate allegations of DDM thermal incidents in model year (MY) 2006-2007 Chevrolet Trailblazer vehicles. Thermal incidents involve cases where fire-related events such as smoke and melt are present. ODI has received 170 reports alleging a thermal event occurred. Complainants stated that the DDM melted and in some cases produced odor and/or smoke. Fourteen of these incidents led to a fire where visible flames were reported or the damage extended significantly beyond the DDM. In addition to the 170 reports listed above, ODI received 63 reports alleging the DDM acted erratically or became inoperative. In response to ODI's Information Request (IR), GM provided 619 unique consumer complaints that related to the alleged problem. Seventy-seven of those reports led to a fire with flame, and 4 reported injuries of smoke inhalation and/or slight burns from contact with hot switches. GM also submitted 20,400 warranty claims for replacement of the DDM, most of which involved inoperative switches. The problem condition is caused by fluids, such as rain water, entering the driver's door module and subsequently causing corrosion that could result in an electrical short in the printed circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. However, the electrical short may also cause overheating that could melt components of the door module, producing odor, smoke or in some cases fire with flame. The circuit board was redesigned and GM implemented the new design into vehicle production on May 14, 2007. All failures cited above occurred in vehicles produced before this build date (i.e., with the original design DDM). GM also reported that all MY 2006-2007 GMT360/370 platform vehicles and MY 2005 SAAB 9-7x vehicles utilized the same DDM and therefore ODI expanded the subject population to include these vehicles.This investigation is closed on the basis of GM's announcement of safety recalls 12V-406 and 13V-248. The ODI complaints cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID, see the attached list for ODI numbers.

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.

ON HIGHWAY US-31 IN MUSKEGON COUNTY MICHIGAN, VEHICLE (ENVOY) WAS AT ALMOST A COMPLETE STOP FOR A VEHICLE STOPPED AHEAD WHEN STRUCK FROM BEHIND BY ANOTHER VEHICLE TRAVELLING AT 70+ MPH. THE ENVOY WAS THEN PUSHED INTO THE VEHICLE IN FRONT OF THE ENVOY. THE ENVOY SUFFERED MAJOR REAR END DAMAGE AND SEVERE FRONT END DAMAGE. NONE OF THE FRONT AIRBAGS DEPLOYED. BOTH FRONT DRIVER AND PASSENGER SEATBELTS DID NOT RESTRAIN. THE SEATBELTS STRETCHED OUT TO THEIR LIMIT. BOTH FRONT DRIVER'S SEAT AND PASSENGER SEAT TWISTED INWARDS TOWARD THE CONSOLE. SEVERE BODILY INJURIES OCCURRED. ON 08/23/2018, GMC WAS MADE AWARE OF THIS. A CASE WAS OPENED. THE EVENT DATA RECORDER WAS RECOVERED BY GMC. THE EDR SHOWED THE IMPACT VELOCITY, NON-DEPLOYMENT OF AIRBAGS AND NON-RESTRAINT OF SEATBELTS. GMC THEN CLOSED THE CASE STATING THAT BECAUSE THERE WAS NO TRAUMATIC BRAIN INJURY, THERE WOULD BE NO FURTHER INVESTIGATION OR COMPENSATION. THE 2006 GMC ENVOY WAS DEEMED A TOTAL LOSS BY THE AUTO INSURER.

STEERING WHEEL LOCKS. IT CANNOT BE TURNED TO THE RIGHT AS IT WILL CAUSE THE ENTIRE CARE TO SWERVE. WHEN REVERSING THE CAR TURNS IN THE OPPOSITE DIRECTION OF WHERE YOU ARE TURNING. I'M BACKING INTO TRAFFIC AND HAVE TO MANUALLY PULL THE STEERING WHEEL AS IF THERE IS A POWER STEERING ISSUE. ENGINE LIGHT CAME ON DAY AFTER PURCHASE INDICATING I NEED CATALYST CONVERTER AND SENSOR. NO WAY TO PREDICT WHICH WAY THE CAR WILL TURN. IF I HIT A BUMP THE CAR SWERVES TO THE RIGHT CAUSING ME TO SWERVE INTO NEXT LANE. IN MOTION I AM CONSTANTLY SWERVING INTO DANGER.

I PURCHASED THIS VEHICLE WITH NEW TIRES ON IT. EXCESSIVE TIRE WEAR WAS STARTING ON THE DRIVERS SIDE TIRE BEFORE THE YEAR MARK OF ME PURCHASING IT. THERE WAS NO RECALLS OPEN ON THAT TIME THAT WE COULD FIND. I HAVE HAD TO REPLACE THE FOG LIGHTS ON SEVERAL OCCASIONS. IT HAD ELECTRICAL SHORT THAT NO ONE SEEMED TO FIND AND THERE WAS NO WAY TO LOCATE WITHOUT EXPENSIVE DIAGNOSTIC TIME. WHEN I WENT TO THE DEALER ABOUT RECALLS THEY INFORMED ME THE ONLY OPEN WAS A WINDOW SWITCH. AFTER A FRONT END ACCIDENT AT 30 MPH THE TIRE BLEW OUT ON THE DRIVERS SIDE ON IMPACT. I WAS INFORMED IN MY ESTIMATE THAT THERE WAS A OPEN RECALL WHICH COULD LEAD TO INCORRECT RIM SELECTION / TIRES FOR THE CAR CAUSING AIR LEAKAGE AND POSSIBLE ACCIDENT. IF I HAD KNOWN THIS BEFORE HAND MAYBE THIS COULD HAVE BEEN PREVENTED!

I HAVE REPLACED THE STEERING WHEEL SENSOR, THE THROTTLE BODY, AND HAD THE RELEARN THE IDLE THING DONE, TO NO AVAIL. THIS MAKES MY FOURTH TIME GOING TO THE DEALER, BECAUSE I THOUGHT THEY COULD FIX IT. I HAVE ALWAYS BOUGHT GM. IF GOD BLESSES ME WITH ANOTHER OPPORTUNITY TO BUY A CAR, IT WILL NOT BE A GM. IT THROWS MY CAR OFF. I'VE HAD TO PULL OVER AND START THE CAR OVER A THOUSAND TIMES. I'VE SEEN MANY FORUMS ONLINE ABOUT THIS PROBLEM, BUT THERE IS NO RECALL? I'VE EVEN CALLED GM. I STILL HAD TO PAY MONEY. RESETTING THE COMPUTER HAS DONE ABSOLUTELY NOTHING. JUST WANTED TO RANT, BECAUSE BESIDES GIVING ME SOME OF MY MONEY BACK (TO THE TUNE OF A GRAND), WHAT CAN I DO?
