I WAS DRIVING ABOUT 25 MILES PER HOUR @ NIGHT WHEN ALL THE WARNING LIGHTS ON THE DASH CAME ON AND ALL THE GAUGES READ ZERO EXCEPT THE SPEEDOMETER AND TACH, TRANSMISSION GEAR SELECTOR WASN'T INDICATING WHAT GEAR I WAS IN & RADIO ALSO KILLED. HEADLIGHTS, WIPERS & DIRECTIONS WERE STILL FUNCTIONAL. I ONLY HAD A MILE TO DRIVE TO GET HOME. PARKED VEHICLE IN GARAGE AND SHUT OFF....ONLY TO DISCOVER THAT POWER LOCKS HAD FAILED AND I WAS LOCKED IN CAR, POWER WINDOWS WERE ALSO OUT! REMOVED KEY FROM IGNITION AND FORTUNATELY THE REMOTE KEY FOB UNLOCKED THE DOOR. HAD THIS BEEN AN EMERGENCY SITUATION, I WOULD HAVE NO WAY TO EXIT THE CAR NOR WOULD ANY PASSENGERS. ANYONE ELSE HAVING THIS PROBLEM? I CONTACTED DEALER TO APPRIZE THEM OF THIS NEW PROBLEM AND WAS ADVISED THAT IF IT'S INTERMITTENT THEY WOULD HAVE PROBLEMS FIXING IT. THE VEHICLE SEEMED TO RESET IN THE MORNING AND ALL DASH WARNING LIGHTS BACK TO NORMAL! *TR

I COULDN'T BELIEVE THAT A 2005 VEHICLE HAD FRAME RUST THAT WENT CLEAR THROUGH THE VEHICLE. I HAVE A 1981 JEEP THAT I USE AS A FARM VEHICLE DOESN'T EVEN HAVE FRAME RUST THROUGH. I AM SURE THAT BEFORE THIS VEHICLE IS PAID OFF IT WILL HAVE A BROKEN FRAME SOON. I JUST CHECKED THE HOLE YESTERDAY AND IT IS GETTING LARGER. VERY POOR METAL USED IN THESE FRAMES. NOT SATISFIED. A FRAME OUGHT TO LAST LONGER THAN THAT. *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.
