ON JULY 28, 2014 I WAS GOING DOWN A HILL AND THE ENGINE SHUT OFF COMPLETELY. FORTUNATELY I WAS ONLY GOING APPROXIMATELY 5 MPH AND WAS ABLE TO COAST ACROSS THE MAIN STREET AND WAS ABLE TO COAST INTO A PARKING SPOT. I TRIED RESTARTING MY ENVOY WITH NO LUCK SO I HAD THE TRUCK TOWED TO THE LOCAL GMC DEALERSHIP AND WAS TOLD THAT THE IGNITION SWITCH HAD GONE BAD. I HATE TO THINK WHAT WOULD HAVE HAPPENED IF I WAS GOING FASTER OR GOING DOWN A STEEP MOUNTAIN BECAUSE WHERE I LIVE I AM SURROUNDED BY MOUNTAINS. I AM NOT SURE IF ANYONE ELSE EXPERIENCED THIS PROBLEM WITH A SIMILAR VEHICLE. I DO KNOW THAT OTHER GM CARS AND VEHICLES ARE BEING RECALLED FOR THIS SAME SITUATION BUT WAS TOLD THAT MINE IS NOT UNDER A RECALL AT THIS TIME. *TR

GMC ENVOY SHUT DOWN WHILE DRIVING. ALL POWER LOST. VEHICLE CAME TO A COMPLETE STOP JUST A FEW FEET BEFORE AN INTERSECTION. DEALER REPLACED IGNITION SWITCH, DUE TO "MULTIPLE CODES STORED IN THE ECM." IRONICALLY, ALMOST 2 YEARS PRIOR, SAME ISSUE WITH THE VEHICLE HAPPENED ON THE EXPRESS WAY. WE WERE LUCKY TO BE ABLE TO GET TO THE SIDE OF THE ROAD BEFORE THE VEHICLE CAME TO A STOP. IGNITION SWITCH WAS REPLACED DURING THAT INCIDENT AS WELL. TWO IGNITION SWITCHES HAVE BEEN REPLACED IN THE SAME VEHICLE OVER THE COURSE OF 2 YEARS. I'M SURPRISED THAT THIS VEHICLE ISN'T PART OF THE GM IGNITION RECALL! *TR

2RQ17002 · 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.
