2006 Isuzu Ascender

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.

MY CHECK ENGINE LIGHT HAS BEEN CONSTANTLY ON. I'VE GOTTEN IT CHECKED BY 3 DIFFERENT PEOPLE. I'VE GOTTEN THE SAME RESPONSE FROM EACH. I WAS TOLD THAT I HAD A MISFIRE, I NEEDED AN OIL PRESSURE SENSOR/SEND UNIT, OXYGEN SENSOR BANK1/BANKA, AND THAT THE OIL WAS LEAKING BAD FROM AROUND THE OIL PRESSURE SENSOR. I GOT THE COILS CHANGED, SPARK PLUGS AND WIRES DONE, CHANGED THE OIL PRESSURE AND OXYGEN SENSORS TOO. ABOUT A COUPLE MONTHS AFTER THAT THE LIGHT WAS BACK ON WITH THE LOW OIL PRESSURE WARNING. THE OIL WAS FINE SO I TOOK IT TO HAVE A DIAGNOSTIC DONE ON IT AND TOOK IT FOR A SECOND OPINION AND THE AGAIN NEEDED AN OXYGEN SENSOR AND OIL PRESSURE SENSOR/SENDING UNIT. I CHANGED THEM AGAIN AND THEY USED THREADING TAPE FOR THE OIL PRESSURE SENSOR TO STOP THE LEAKING OF OIL. I'VE SPENT AROUND $800 SO FAR AND 2 MONTHS LATER THE LIGHT IS BACK ON NEEDING THE SAME THINGS, OIL PRESSURE SENSOR AND OXYGEN SENSOR. I TOOK IT TO HAVE IT CHECKED WITH A SECOND OPINION AND WAS TOLD THAT MAYBE IT'S A DEFECT IN THE COMPUTER SYSTEM OR SOMETHING ELECTRICAL THAT KEEP TAKING OUT THOSE SENSORS BECAUSE EVERYTHING ELSE IS WORKING FINE. WHEN I START MY VEHICLE UP FROM SITTING OVER NIGHT, THE ENGINE LIGHT COMES ON AND STAY ON AND THE LOW OIL PRESSURE WARNING STAYS ON WHILE IDLING. WHEN I START DIVING THE LOW OIL PRESSURE WARNING GOING OFF UNTIL I STOP, THEN IT'S BACK ON. I CUT THE VEHICLE OFF IF I'M STOPPED AT A TRAFFIC LIGHT THEN BACK ON TO FINISH DRIVING. IF I DRIVE FOR ABOUT 15 OR 20 MINUTES, THE LOW OIL PRESSURE WARNING STAYS OFF UNTIL I START IT UP AGAIN THE NEXT TIME. IT MIGHT BE A DEFECT WITHIN THE SYSTEM AND HOPE SOMEONE WILL FIND THE CAUSE BECAUSE TO KEEP GETTING THE SAME REPAIRS OVER AND OVER AGAIN IS EXPENSIVE. ITS $150 JUST TO HAVE THE OXYGEN SENSOR CHANGED NOT INCLUDING THE PART AND THE PART IS $65, AND IF GOING TO CAR DEALERS IS DOUBLE OR TRIPLE THAT AMOUNT. PROBLEMS FROM 2014 TIL CURRENT

THE ISSUE STARTED WITH MY LIGHTS STAYING ON. THE CAR WAS PARKED IN MY DRIVEWAY AND TURNED OFF COMPLETELY. MY BATTERY WAS DYING AND I FINALLY SEEN THAT SOME OF MY LIGHTS OUTSIDE OF THE CAR WERE NOT SHUTTING OFF. I TRIED MANUALLY SHUTTING THEM OFF AND THAT DID NOT WORK. NOW MY HEAT AND AIR DOES NOT WORK. I'M SURE IT HAS TO DO WITH THE FUSE BOX UNDER THE BACK DRIVER'S SIDE SEAT. WHEN I WENT TO CHECK THE FUSES IT SHORTED OUT WHEN I PULLED THE COVER OFF. I HOPE MY CAR DOES NOT CATCH FIRE NEXT. I DO HAVE THE ISSUE WITH MY DRIVER DOOR NOT WORKING. IT WORKED WHEN I FIRST GOT THE CAR, A COUPLE MONTHS LATER MY DRIVER DOOR WINDOW WORKED INTERMITTENTLY. EVENTUALLY IT STOPPED WORKING COMPLETELY. WHEN I CALLED ISUZU THEY TOLD ME I HAD TO TRAVEL TO ALABAMA IF I WANTED THEM TO FIX IT. OTHERWISE I COULD HAVE A MECHANIC DO IT AND I WOULD BE REIMBURSED, I JUST DONT HAVE 7-$800 TO THROW OUT THERE.
