ABS AND BRAKE WARNING LIGHTS AND WARNING CHIME COMES ON EVERY TIME WE DRIVE THE CAR. THE CHIME WILL GO OFF AFTER ABOUT 15 SEC. OF CHIMING. LIGHTS AND WARNING ON THE "READOUT" STAY ON. OUR MECHANIC SAID ITS THE ABS MODULE AND GM DOESN'T HAVE ANY. THEY HAVE BEEN ON BACKORDER FOR AT LEAST 8 MONTHS. HE SAID IT'S A PROBLEM WITH "LIKE" GM VEHICLES ALSO. THIS IS A SAFETY HAZARD. DON'T KNOW TO TAKE IT SERIOUSLY OR NOT. DON'T KNOW IF OUR BRAKES ARE GOING TO WORK. WE NEED THIS FIXED AND WE CAN'T EVEN GET A PART. HELP!! *TR

I OWN A 2004 ISUZU ASCENDER. THERE HAS BEEN A HOST OF PROBLEMS THAT I HAVE HAD TO DEAL WITH IN THE MINIMAL 10 MONTHS THAT I HAVE OWNED THE VEHICLE. TWO OF THE PROBLEMS HAVE YET TO RECEIVE ANY TYPE OF FIX FROM THE LOCAL ISUZU SERVICE CENTER. THE FIRST PROBLEM WAS THE BELT SCREAMING EVERY DAY. I TOOK THE VEHICLE IN THREE TIMES FOR THE BELT AND THEY FINALLY FIXED IT. THE SECOND PROBLEM IS ALL FOUR DOOR WINDOWS. DEBRIS CONSISTENTLY MAKES ITS WAY INTO THE DOOR AND ANY TIME I ROLL DOWN OR ROLL UP MY WINDOWS MY WINDOWS GET SEVERLY SCRATCHED. I ADDRESSED THIS ISSUE WITH THE SERVICE CENTER AND THEY SAID THERE IS NOTHING THEY CAN DO ABOUT IT AND THAT IT IS NOT A PRODUCT MALFUNCTION. I HAVE NEVER HAD A VEHICLE DO THIS AND NOR DO I KNOW ANYONE THAT HAS HAD A SIMILAR ISSUE. LASTLY AND MOST IMPORTANTLY, MY FAMILY AND I WERE ON A ROUTINE DRIVE BACK FROM NEW HAMPSHIRE. THE CONDITIONS WERE CLEAR AND THE ROADS WERE OF TYPICAL NEW ENGLAND REPAIR. A VEHICLE PULLED OUT IN FRONT OF OURS AND IN REACTION I APPLIED HEAVY, NOT EXCESSIVE, PRESSURE TO THE BREAK PEDAL. THE PETAL STARTED TO CLICK, MOST LIKELY THE ABS, BUT NOTHING KICKED IN TO STOP MY VEHICLE. WHEN I SAY NOTHING, IT WAS LIKE I NEVER STEPPED ON THE BREAK AT ALL. I HAD TO SWERVE IN TO THE OTHER LANE OF TRAFFIC TO AVOID A COLLISION. THE NEXT DAY I TOOK THE VEHICLE IN TO BE LOOKED AT AND THE SERVICE DEPARTMENT SENT MYSELF AND A MECHANIC OUT ON A ROAD TEST IN HOPES TO DUPLICATE THE MALFUNCTION. I DID NOT HAVE ANY REAL LUCK WITH DUPLICATING THE MALFUNCTION BUT I KNOW IT EXISTS. IT HAS HAPPENED TO MY WIFE THREE TIMES AND MYSELF ONCE. THE SERVICE DEPARTMENT SAID THERE IS NOTHING THEY CAN DO RIGHT NOW AND TO WAIT FOR A GM CERTIFIED MECHANIC TO HAVE THE OPPORTUNITY TO LOOK AT MY VEHICLE. THE BREAKS HAVE GONE UNCHECKED SINCE THE LATEST INCIDENT AND MY CONFIDENCE IN THE SAFETY OF THE VEHICLE WAVERS MORE AND MORE EVERY DAY.

RQ17002 · 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.
