2005 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.

DRIVING AT NIGHT ON HIGHWAY AND MY EXTERIOR LIGHTS WILL GO COMPLETELY OFF AND ONLY MY HIGH BEAMS WILL COME ON BUT THAT'S IT. THEY'LL COME BACK ON USUALLY WHEN I GET TO WHERE I'M GOING AND PARK THE CAR BUT DRIVING ON THE HIGHWAY AT NIGHT AND ALL OF THE SUDDEN YOUR HEADLIGHTS GO OUT IS EXTREMELY DANGEROUS. ON THREE DIFFERENT OCCASIONS BOTH THE HIGH BEAM AND LOW BEAMS WENT OUT. BUT ON MOST OCCASIONS AND NOW EVERY OCCASION WHILE DRIVING AT NIGHT THE REGULAR LOWBEAM HEADLIGHTS JUST GO OUT RANDOMLY

THE LIGHTS GO OFF WHILE DRIVING AT NIGHT. IT IS THE SAME PROBLEM AS WITH THE ASCENDER 2006-2008 RECALL, BUT DOES NOT INCLUDE THE 2005. THE HDM HAS GONE OUT. IT HAS HAPPENED SEVERAL TIMES IN THE PAST 4 MONTHS ONLY TO GO OUT AND NOT COME BACK ON THIS LAST TIME 03/01/2016. I SHOULD NOT HAVE TO PAY TO HAVE IT REPLACED. I NOTICED ON THE INTERNET THAT OTHER PEOPLE HAVE HAD THE SAME PROBLEM WITH THE CAR PRIOR TO 2006 MODEL. THEY SHOULD COVER THE COST ON THIS CAR SINCE IT IS THE EXACT SAME PROBLEM AS THE RECALL 14V755000 11/26/2014 AND SECOND NOTICE OF RECALL 08/18/2015. THE 2005 MODEL SHOULD BE INCLUDED.
