WHEN I FIRST BOUGHT MY 2002 TRAILBLAZER, THE FAN CLUTCH WOULD OCCASIONALLY BE FULLY ENGAGED WHEN I STARTED THE TRUCK IN THE MORNING. IT USUALLY RESUMED NORMAL FUNCTION WITHIN A MILE OR SO. AS OF YESTERDAY, IT WILL NOT DISENGAGE AND THE CHECK ENGINE LIGHT CAME ON. IT SOUNDS LIKE THE LABOR TO REPLACE THIS CLUTCH IS VERY HIGH. I'M NOT SURE IF I DARE TACKLE THIS MYSELF, BUT THE THOUGHT OF PAYING $700 TO REPLACE SOMETHING THAT SHOULDN'T FAIL AT 47,000 MILES IS DISGUSTING. *NM

THERE IS A LOUD ROARING SOUND FROM UNDER THE HOOD. (SOUNDS LIKE A JET ENGINE.) VEHICLE DEALER SAYS THAT VEHICLE HAS A BAD COOLING FAN CLUTCH AND THAT THE RELATED COMPUTER SOFTWARE NEEDS REPROGRAMMING. THIS LOUD NOISE PROBLEM USED TO ONLY HAPPEN WHEN THE VEHICLE WAS COLD AND WOULD GO AWAY AFTER ABOUT A HALF MILE. VEHICLE APPEARS NOT TO SHIFT PROPERLY (AUTOMATIC TRANSMISSION) AND THE VEHICLE DOES NOT ACCELERATE WELL WHILE THIS LOUD SOUND IS PRESENT. SOMETIMES NOW THE PROBLEM OCCURS WHEN THE VEHICLE IS WARMED-UP. THE LOUD NOISE GOES AWAY AFTER A SHORT WHILE. *NM

2002 CHEVY TRAILBLAZER HAS A SERIOUS FAN CLUTCH PROBLEM. VEHICLE HAS 52,000 MILES. THE CLUTCH FAN STAYS ENGAGED AT ANY SPEED, VEHICLE WILL SUDDENLY LOOSE ACCELERATION AND ALSO GETS POOR GAS MILEAGE. CHECK ENGINE LIGHT EVENTUALLY CAME ON ABOUT 2 WEEKS AFTER THE VEHICLE STATED TO SOUND LIKE A TANK. WILL TAKE THIS TO A LOCAL MECHANIC AS BASED OFF OF THE AMOUNT OF COMPLAINTS ON THE WEB WITH OTHER PEOPLE HAVING THE SAME PROBLEM, AND THE DEALER CHARGING $700.00 TO REPAIR WHEN THE PART CAN ACTUALLY BE PURCHASED LOCALLY FOR $229.00. THERE ARE DEFINITE PROBLEMS WITH THIS AND BASED OFF OF ALL THE OTHER COMPLAINTS GM IS WELL AWARE THAT THERE IS A PROBLEM, AND WILL DO NOTHING ABOUT IT. *JB

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.
