TL*THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. IF THE CONTACT DOES NOT UNHOOK THE BATTERY POST EACH NIGHT, THE VEHICLE WILL NOT START IN THE MORNINGS. SHE PURCHASED A NEW BATTERY, BUT THE FAILURE PERSISTS. THE FRONT PASSENGER SIDE OF THE VEHICLE NEAR THE TIRE MAKES A ROARING SOUND INTERMITTENTLY. NEITHER WEATHER NOR SPEED WERE FACTORS. THE CONTACT BELIEVES THAT THE GAS TANK IS LEAKING FUEL BECAUSE IT IS BURNING MORE FUEL. THE VEHICLE WAS NOT TAKEN TO A CHEVROLET DEALER, BUT WAS TAKEN TO THE DEALER FROM WHERE THE VEHICLE WAS PURCHASED. THE MECHANIC STATED THAT THE VEHICLE WAS EXPERIENCING ELECTRICAL FAILURE AND SHOULD BE TAKEN TO THE DEALER. THE CONTACT WAS INFORMED THAT THE FOLLOWING NHTSA CAMPAIGN ID NUMBERS DID NOT APPLY TO HER VIN: 01V126000 (SUSPENSION:FRONT:CONTROL ARM:LOWER ARM), 03V096000 (ELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASH), AND 02V121000 (FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS).

JUST AS MANY OTHER 2002 CHEVY TRAILBLAZER OWNERS HAVE FOUND, ONE DAY THERE WAS A LOUD FAN NOISE WHEN ACCELERATING, REDUCED GAS MILEAGE, AND A LACK OF ABILITY TO ACCELERATE THAT LASTS FOR ABOUT A MILE. AFTER A FEW MINUTES OF SEARCHING ON THE INTERNET IT IS APPARENT THAT MY PROBLEM IS THE FAN CLUTCH, TSB 060602003, NHTSA 10019510. IT APPEARS THAT THOUSANDS OF OWNERS ARE HAVING THE SAME PROBLEMS AND HAVE BEEN FOR YEARS BUT THERE IS STILL NO RECALL. ALTHOUGH THIS PROBLEM IS INTERMITTENT AT THIS TIME IT ALMOST CAUSED A SERIOUS ACCIDENT THE FIRST TIME IT HAPPENED. I WAS MERGING ONTO A HIGHWAY AND COULDN'T GET THE ENGINE OVER 30 MILES PER HOUR. WE WERE NEARLY REAR-ENDED. I HAVE COPIES OF AT LEAST A THOUSAND INTERNET COMPLAINTS WITH THE FIRST ONE POSTED AROUND NOVEMBER 2001 --- JUST ABOUT THE TIME WE PURCHASED THE VEHICLE NEW. (IF YOU DON'T KNOW IT ALREADY THERE ARE WEBSITES JUST FOR THE PURPOSE OF COMPLAINING ABOUT THE CHEVY TRAILBLAZER!!!) I CAN'T BELIEVE THAT GM WOULD TURN AWAY FROM IT'S CUSTOMERS LIKE THIS! I CERTAINLY DOESN'T MAKE ME WANT TO PURCHASE AMERICAN MADE AGAIN! *TR

THE ELECTRICAL GAUGES ON OUR 2002 CHEVY TRAILBLAZER DID NOT FUNCTION PROPERLY WHEN THE FAN CLUTCH FAILED, LEADING TO ENGINE OVERHEATING. THE OVERHEATED ENGINE BLEW THE HEAD GASKET BEFORE THE ENGINE ITSELF BLEW UP. MY HUSBAND WAS HAD JUST BACKED OUT OF THE DRIVEWAY AND HAD DRIVEN ABOUT 200 YARDS WHEN THIS HAPPENED. IT IS IMPORTANT TO NOTE THAT WARNING SYSTEMS MALFUNCTIONED: THERE WERE NO LIGHTS, BELLS OR ANY INDICATION THAT COMPLETE ENGINE FAILURE WAS IMMINENT. THERE WASN'T EVEN THE ODOR OF AN OVERHEATED ENGINE. IF THIS HAD HAPPENED ON OUR LOCAL FREEWAY I COULD BE SUING GM OVER MY HUSBAND'S INJURY OR DEATH. *TR

LOUD ROARING NOISE THAT SOUNDS LIKE A JET PLANE. WAS INTERMITTENT, BUT NOW CONSTANTLY. THE NOISE IS EVEN LOUDER WHEN YOU ACCELERATE. THE FAN IS TURNING AT AN ASTRONOMICAL RATE OF SPEED AND GAS MILEAGE NOW IS ONLY ABOUT 9 MPG. RIGHT BEFORE THIS CONSTANT JET PLANE SOUND STARTED, THE BATTERY BLEW UP. YES, BLEW UP! AND THE TRUCK WOULD DIE IF THE A/C WAS TURNED ON. THE DEALER TOLD ME IT WAS THE WATER PUMP AND THE PULLEY AND BELT ALSO NEED TO BE REPLACED.

I PURCHASED A 2002 CHEVROLET TRAILBLAZER FROM YOUNGER TOYOTA IN HAGERSTOWN, MD ON MAY 12, 2007. APPROXIMATELY A WEEK AND A HALF AFTERWARDS, I CONTACTED THE SALESMAN THAT SOLD US THE VEHICLE, PHIL YOUNG, COMPLAINING THAT THE TRANSMISSION WAS MAKING A NOISE AND THE VEHICLE WASN'T SHIFTING CORRECTLY. HE TOLD ME TO BRING IT IN TO THE SERVICE DEPARTMENT. MY HUSBAND (NOT CAR SAVVY) SAID THAT THE NOISE WAS COMING FROM THE UNDERSIDE OF THE TRAILBLAZER AND FELT IT MIGHT BE THE BRAKES CAUSING THE NOISE AND JERKING. I STUCK TO MY GUNS THAT IT WAS THE TRANSMISSION AND WANTED IT REPAIRED WHILE IT STILL HAD THE 30 DAY WARRANTY. YOUNGER DENIED IT WAS THE TRANSMISSION AND NOTED MY HUSBAND'S THEORY OF THE BRAKES, BUT NOTHING ABOUT MY COMPLAINT CONCERNING THE TRANSMISSION. THE TRAILBLAZER WAS TAKEN BACK 2 OR 3 MORE TIMES TO THE SERVICE DEPARTMENT, WE DEMANDED THEY FIX IT. THE TRAILBLAZER SAT IN THEIR LOT FOR THREE WEEKS BECAUSE WE WOULD TEST DRIVE IT AND BRING IT RIGHT BACK STATING THAT THE PROBLEM WAS STILL THERE. ON OR AROUND JANUARY 14, 2008 THE TRAILBLAZER BROKE DOWN IN CHARLESTOWN, WV. WE TOOK IT BY CREAMERS AUTOMOTIVE, THEY ASKED WHAT THE SYMPTOMS WERE AND THE MECHANIC DROVE AROUND THE BLOCK WITH ME, INSTANTLY STATED THAT IT WAS THE SUNSHELL IN THE TRANSMISSION AND THAT THEY HAD SOMEONE IN EARLIER THAT WEEK WITH THE SAME PROBLEM. THEY HAD PURCHASED THEIR VEHICLE AT YOUNGER AUTOMOTIVE AS WELL AND THEY DENIED THE TRANSMISSION PROBLEMS AND WOULDN'T NOTE IT ON THEIR PAPERWORK AS WELL. IN MY RESEARCH OF THIS PROBLEM, I FOUND IT TO BE VERY WIDESPREAD, THERE ARE HUNDREDS OF COMPLAINTS ON ONE WEBSITE ALONE. THE SUNSHELL IS A FAULTY PART THAT SHOULD BE RECALLED BY GM. SOMEONE IS GOING TO BE HURT OR EVEN KILLED IF THIS ISN'T TAKEN CARE OF IMMEDIATELY. GM IS FULLY AWARE OF THIS PROBLEM, THERE HAVE BEEN HUNDREDS, MAYBE EVEN THOUSANDS OF COMPLAINTS ON THIS PARTICULAR VEHICLE AND SHOULD TAKE OWNERSHIP OF A PRODUCT THEY PRODUCE AND SELL. *TR

THIS VEHICLE WOULD GO OUT OF GEAR WITHOUT WARNING BECAUSE OF A FAULTY 4 WHEEL DRIVE SWITCHING SYSTEM. THIS OCCURRED IN TRAFFIC, AND AN UNOCCUPIED PARK SITUATION. THE VEHICLE WENT OUT OF PARK AND ROLLED INTO A DOOR WHILE IN THE GARAGE. THE VEHICLE ALSO WENT OUT OF GEAR IN TRAFFIC SITUATIONS CAUSING THE DRIVER TO FIND THE ROAD SHOULDER. IF THE DRIVER MANIPULATED THE SWITCH IT WOULD SOMETIMES RE-ENGAGE THE TRANSMISSION. AN ENCODER MOTOR SENSOR WAS REPLACED, THEN FAILED IN TWO WEEKS. IT WAS THEN DIAGNOSED THAT THE ENCODER MOTOR WAS FAULTY AND CAUSING THE ENCODER SENSOR TO FAIL. REPLACED MOTOR AND SENSOR AGAIN. THIS IS A DEFECT THAT SHOULD BE PART OF THE EXISTING RECALL FOR ALL 2002 CHEVROLET TRAILBLAZERS, NOT JUST THE SELECT FEW AS PRESCRIBED TODAY. *TR

I STARTED RESEARCHING COMPLAINTS ABOUT THE TRANSMISSIONS AND REALIZED THERE ARE OVER 82 COMPLAINTS AND THAT GM HAS KNOWN ABOUT THIS FAULTY PART CALLED A SUNSHELL THAT'S WEAK METAL AND THE TORK IN THE ENGINE OF THE V6 CANT HANDLE THE PRESSURE SO IT EVENTUALLY CRACKS AND BREAKS THEN YOU DEAD IN THE WATER. THIS COULD HAVE BEEN A REAL SAFETY HAZARD AND FOR MANY I HAVE READ ABOUT THEIR PROBLEMS WITH CHILDREN IN THE CAR ITS AMAZING NO ONE HAVE BEEN KILLED YET. GM REFUSED TO HAVE A RECALL ON THIS PROBLEM DUE TO THE EXPENSE AND IS PASSING THIS DOWN TO ITS CONSUMERS TO BEAR THE BURDEN. WILL I PURCHASE ANOTHER GM CAR? NOT ON YOUR LIFE!

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.

THE SUBJECT VEHICLES (CHEVROLET TRAILBLAZER (EXT), GMC ENVOY (XL), AND OLDSMOBILE BRAVADA) ARE BUILT ON THE GMT360 AND GMT370 PLATFORMS AND WERE ORIGINALLY EQUIPPED WITH A WINDSHIELD WIPER ASSEMBLY REFERRED TO AS THE ?FAMILY? DESIGN MODULE (P/N 15171306 BASE, P/N 15171307 FOR VEHICLES EQUIPPED WITH RAINSENSE AUTOMATIC MOISTURE SENSITIVE WIPERS).THE WINDSHIELD WIPER ASSEMBLY IS LOCATED INSIDE THE PLENUM AT THE BASE OF THE WINDSHIELD AND IS MOUNTED ON AN INCLINE APPROXIMATELY EQUAL TO THE RAKE OF THE WINDSHIELD.GM REPORTS THAT VEHICLES ARE SUBJECT TO A QUALITY ASSURANCE WATER TEST AT THE ASSEMBLY PLANT.THE TEST EXPOSES THE VEHICLES TO AN AMOUNT OF WATER THAT EXCEEDS THE PLENUM?S CAPABILITY TO DIVERT WATER AWAY FROM THE WIPER MODULE, ALLOWING WATER TO RISE TO A LEVEL THAT EXCEEDS THE HEIGHT OF THE WINDSHIELD WIPER MOTOR COVER VENT HOLE.WATER ENTERS THROUGH THE VENT HOLE THEN FLOWS DOWN TO THE BOTTOM OF THE MODULE AND POOLS CAUSING THE ELECTRICAL COMPONENTS ON THE CONTROL CIRCUIT BOARD TO CORRODE AND SHORT OUT, THUS RENDERING THE WIPER MOTOR/MODULE INOPERATIVE.ON NOVEMBER 2, 2002 GM INTRODUCED INTO VEHICLE PRODUCTION A REDESIGNED WINDSHIELD WIPER ASSEMBLY REFERRED TO AS THE ?GLOBAL? DESIGN MODULE (P/N 15094704 BASE, P/N 15094705 FOR VEHICLES EQUIPPED WITH RAINSENSE) THAT USES A POLYTETRAFLUOROETHYLENE MEMBRANE COVERED VENT HOLE TO CONTROL WATER INTRUSION.THERE ARE A TOTAL OF 1,172 NON-DUPLICATIVE OWNER AND FIELD REPORTS ALLEGING WINDSHIELD WIPER FAILURE, TWO VEHICLE CRASHES ALLEGEDLY CAUSED BY WINDSHIELD WIPER FAILURE, AND 43,219 WARRANTY CLAIMS FOR WINDSHIELD WIPER ASSEMBLY OR WIPER CONTROL MODULE REPLACEMENT ON VEHICLES ORIGINALLY EQUIPPED WITH THE ?FAMILY? DESIGN MODULE.THIS PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA04-002) TO FURTHER STUDY THE SCOPE AND SAFETY CONSEQUENCES OF THIS ISSUE.
