THE TIRE FAILURE OCCURRED WHILE DRIVING EASTBOUND I-10 IN THE RIGHT LANE, APPROX. 40 MILES WEST OF PHOENIX AZ. THE LOCAL TIME WAS APPROX. 3:30 PM. OUTSIDE TEMP. WAS 102 F ACCORDING TO THE VEHICLE'S THERMOMETER. THE VEHICLE WAS NORMALLY LOADED, & WAS INSPECTED PRIOR TO DEPARTING ON THE TRIP - INCLUDING TIRE PRESSURE & TREAD WITHIN SPECIFICATIONS. MY WIFE WAS DRIVING AT 75 MILES PER HOUR WHEN WE BOTH SENSED AN ABNORMAL VIBRATION FROM THE REAR OF THE VEHICLE. THE SENSATION WAS SIMILAR TO DRIVING OVER HEAVILY GROOVED CONCRETE. MY WIFE ASKED WHAT I THOUGHT OF IT, & I ASKED HER TO CHANGE THE VEHICLE'S SPEED TO SEE IF THE SOUND CHANGED. SHE DECELERATED AROUND 5-10 MPH, THEN WAS ACCELERATING AGAIN WHEN WE HEARD A LOUD EXPLOSION FROM THE LEFT REAR OF THE VEHICLE. THE ENTIRE SUV WAS JOLTED AS IF WE HAD BEEN STRUCK FROM BEHIND, FOLLOWED BY A LOUD FLAPPING/THUMPING SOUND. I FELT THE VEHICLE YAW TO THE LEFT, THEN FISHTAIL RIGHT - LEFT - AND RIGHT AGAIN. THIS YAW OSCILLATION WAS ACCOMPANIED BY A COUPLED ROLLING MOTION. MY WIFE DID NOT APPLY STEERING WHEEL OR BRAKE INPUTS, & REMOVED HER FOOT FROM THE GAS. THE VEHICLE OSCILLATIONS DAMPED & THEN WE COASTED OFF ONTO THE RIGHT SHOULDER. UPON INSPECTION, THE AFT LEFT TIRES TREAD SEPARATED FROM THE TIRE BODY. THE SIDEWALL SPLIT IN MULTIPLE LOCATIONS. THE TIRE TREAD WAS BROKEN INTO TWO SECTIONS CIRCUMFERENTIALLY AND WRAPPED AROUND THE AXLE, BRAKE, & SUSPENSION ASSEMBLIES. THIS REQUIRED SUBSTANTIAL FORCE TO UNWRAP & REMOVE. ADDITIONALLY, THE LOWER AFT PORTION OF THE AFFECTED WHEEL WELL WAS BENT FORWARD TOWARD THE AXLE INTO THE SPACE NORMALLY OCCUPIED BY THE TIRE. FINALLY, THE VEHICLE'S REAR FENDER WAS CRACKED IN THE AREA BEHIND THE LEFT REAR TIRE. THE DAMAGED TIRE WAS REMOVED & THE WHEEL WELL METAL WAS BENT OUT OF THE WAY ON SITE SO THE SPARE COULD BE INSTALLED. THE APPRAISAL & REPAIR PROCESS IS ONGOING. THE TIRE WAS UNDER OEM WARRANTY, & THE MANUFACTURER HAS BEEN NOTIFIED TO EXPECT A CLAIM. *TR

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.
