2007 Isuzu Ascender

2 Defect Investigations from the NHTSA

NHTSA Defect Investigations for the 2007 Isuzu Ascender

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2007 Isuzu Ascender, both ongoing and closed, are listed below:

  1. INVESTIGATION: Driver's Master Power Window Switch

    NHTSA Engineering Analysis #EA12004

    Component(s): Electrical System
    Visibility:Power Window Devices And Controls

    Summary: 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.

  2. INVESTIGATION: Loss of Headlights

    NHTSA Defect Investigation #RQ17002

    • Status:
    • Date Opened: April 24, 2017
    • Date Closed: N/A
    • Recall: No recall yet

    Component(s): Exterior Lighting:Headlights

    Summary: In August 2015, General Motors LLC launched safety recall 15V-519 to address problems with the Headlamp Driver Module (HDM) in the following vehicles: model year (MY) 2005-2009 Buick LaCrosse, 2006-2007 Chevrolet Trailblazer/GMC Envoy/Buick Rainier, 2006 Chevrolet Trailblazer EXT/GMC Envoy XL, 2006-2008 Isuzu Ascender/Saab 9-7X, and 2007 Pontiac Grand Prix vehicles. According to General Motors, the HDM may not operate properly in the thermal environment of the underhood electrical center. If the HDM is not operating correctly, the low beam headlamps and daytime running lamps could fail to illuminate. This failure could be intermittent or permanent. This condition does not affect the high-beam headlamps, marker lamps, turn signals, or fog lamps. Since the recall was launched, Office of Defects Investigation (ODI) has received 128 complaints alleging problems with the headlights from vehicle owners that claim their vehicle is outside the scope of 15V-519 but within the recall's scope of model years. Complaints report simultaneous loss of both headlights with no warning. Some of the complaints include repair orders that show the same component being replaced that was replaced in the recall.A Recall Query has been opened to assess the scope of recall 15V-519.Supporting complaint numbers are listed below:10691447 10684020 1069048110664847 10717216 10714991 10714478 10695413 10725507 10745918 10731703 10747924 10747926 10749723 10724632 10773963 10776403 10760345 10760365 10679481 10690893 10682698 10682702 10809166 10818439 10785626 10786065 10787215 10788724 10790016 10810721 10810884 10807723 10790658 10781537 10780758 10783402 10825298 10823227 10850628 10845800 10839163 10838696 10701506 10703594 10860870 10860687 10862793 10731905 10887353 10875954 10721882 10894398 10892195 10871856 10759384 10781045 10785095 10750160 10790601 10790394 10809745 10810149 10903228 10903407 10811671 10819914 10819760 10837929 10849938 10850160 10853139 10854396 10860027 10861241 10863096 10871869 10872228 10870137 10903120 10897472 10903639 10906323 10910448 10910597 10898565 10914066 10915561 10916437 10904642 10918034 10917754 10892370 10917697 10918865 10925739 10927343 10927833 10927863 10928852 10929021 10929910 10930110 10933640 10933867 10935543 10935614 10935656 10936532 10937256 10923914 10938577 10923936 10924189 10947017 10714124 10695531 10807422 10948192 10920570 10928717 10954928 10956547 10959747 10966006 10966466 10968726 10971648
