2002 CHEVROLET TRAILBLAZER Complaints

TL*THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 45 MPH, THE CONTACT HEARD A LOUD NOISE UNDERNEATH THE VEHICLE. UPON ARRIVING HOME, HE DISCOVERED THAT HE COULD NOT SHIFT INTO REVERSE. CHEVROLET HAS NOT BEEN NOTIFIED. THE CURRENT AND FAILURE MILEAGES WERE 53,673. UPDATED 12/12/07

THE SPEEDOMETER NO LONGER DISPLAYS THE CORRECT SPEED. IT WILL STILL DISPLAY THE SPEED BUT IS VERY DIFFERENT THAN THE ACTUAL SPEED OF THE VEHICLE. WHEN THE VEHICLE IS IN PARK THE NEEDLE WILL BE WELL BELOW 0. *TR

JAN/FEB 2007. SWITCHED TRAILBLAZER INTO 4 WHEEL DRIVE HIGH FOR FIRST TIME SINCE PURCHASE (APRIL 2006), AND WOULD NOT TRANSFER INTO 4 WHEEL DRIVE. TOOK TO LOCAL GM DEALER, REPLACED CONTROL MODULE, COST AROUND $700. OCTOBER 24, 2007 WHILE TRAILBLAZER WAS IN PARK AND RUNNING THE VEHICLE CHANGED FROM 2 WHEEL DRIVE TO 4 WHEEL DRIVE LOW. THE SWITCH WAS STILL IN THE 2 WHEEL DRIVE POSITION. THE VEHICLE WOULD NOT CHANGE BACK INTO 2 WHEEL DRIVE AT ALL. I TOOK THE VEHICLE TO THE GM DEALER AND THEY REPLACED THE ENCODER MOTOR. NOVEMBER 20, 2007. LEFT VEHICAL RUNNING WHILE IN PARK. WENT INTO A FAMILY MEMBERS HOUSE,THEN RETURNED TO VEHICLE AND BEGAN TO BACK OUT OF DRIVEWAY. AS I WAS BACKING UP, THE VEHICLE STOPPED, AS IF I HAD BACKED INTO AN OBJECT (IE, ANOTHER CAR), I PULLED FORWARD BACK INTO THE DRIVEWAY, AND LOOKED AROUND, SAW NOTHING, AND WAS GOING INTO THE HOUSE TO GET A FLASHLIGHT WHEN THEY NOTICED THAT YET AGAIN, THE TRAILBLAZER HAD CHANGED INTO 4 WHEEL DRIVE AGAIN. THIS TIME I WAS ABLE TO GET THE VEHICLE BACK INTO 2 WHEEL DRIVE, AND DRIVE THE VEHICLE HOME. I HAVE MADE AN APPOINTMENT TO HAVE THE 4 WHEEL DRIVE SYSTEM CHECKED AGAIN. TOTAL COST FOR REPAIRS TO 4 WHEEL DRIVE SYSTEM JANUARY TO DATE IS MORE THAN $1200. *TR

REMOTES QUIT WORKING, LIFTGATE WOULD NOT OPEN, REAR WIPER NOT WORKING. I HAD THIS ISSUE BACK IN MAY '05 AND REPLACED ENGATE MODULE. SAME ISSUES OCCURRING AGAIN. I AM SURE I WILL HAVE TO REPLACE ENGATE MODULE AGAIN. *TR

2002 TRAILBLAZER LTZ THE CURRENT AND FAILURE KILOMETRES ARE 106,545 KM. THE VEHICLE BEGAN TO HAVE A STRONG ODOR OF GAS INSIDE AND OUT. IT SEEMED AS IF WE WERE CONSUMING GAS AT A VERY HIGH RATE. HAD THE VEHICLE CHECKED AND IT WAS NOT VISIBLE WHERE THE VEHICLE WAS DRIPPING FUEL. NOTHING WAS FOUND. LATER TOOK VEHICLE TO THE DEALER AND WAS FOUND TO HAVE CORRODED FUEL LINES ON THE FUEL MODULE SENDING UNIT ON THE TOP OF THE FUEL TANK. AT A REPAIR COST OF $850.00. WE FEEL THIS IS A SAFETY ISSUE AS IT COULD HAVE CAUGHT ON FIRE AT ANY TIME. WE UNDERSTAND THERE IS AN INVESTIGATION REPORT (NHTSA ACTION#EA07-009) BEING DONE. THIS MANUFACTURERS DEFECT IS A SERIOUS THREAT TO PEOPLE DRIVING THIS TYPE OF VEHICLE. PARTS SUCH AS THESE SHOULD LAST LONGER THAN 100,000 KILOMETERS. WE HAVE RETAINED OLD PART FROM DEALER. *TR

WIPER STUTTER AND STOP COMPLETELY WITHOUT WARNING WHILE IN INTERMITTENT MODE. *TR

AT ABOUT 40,000 MILES IT STARTED MAKING A LOUD ROARING NOISE AT START UP UNTIL YOU GET ABOUT A MILE DOWN THE ROAD. I CHANGED THE PLUGS AND AIR FILTER AT 60,000 AND THE NOISE SEEMED TO GO AWAY. IT WAS SOON REPLACED WITH A SQUEAKING NOISE FROM THE BELT AREA. I TOOK IT IN TO HAVE THE BELT REPLACED AND $90 LATER THAT DIDN'T FIX THE SQUEAKING NOISE. AFTER A LITTLE RESEARCH ON THE WEB I FOUND OUT ABOUT THE FAN CLUTCH PROBLEM AND THE WATER PUMP BEARINGS WERE GOING BAD. SO I REPLACED THE FAN CLUTCH AND THE WATER PUMP MYSELF FOR $300. THE ROAR IS NOT AS BAD NOW BUT STILL THERE, SHIFTS ABNORMALLY, AND NOW AT 60 MPH IT JERKS FORWARD AND RPMS GO FROM 1500 TO 2000. I RESEARCHED MORE ON WEB AND FOUND THAT AFTER CHANGING THE FAN ASSEMBLY YOU MUST GET THE PCM UPDATED. I CALLED THE LOCAL DEALER (MAROONE) AND THEY WANT $104 TO DO THAT. ANY INFORMATION WOULD BE GREATLY APPRECIATED. *TR

I WAS DRIVING DOWN THE ROAD (FORTUNATELY IN A 25 MPH ZONE) WHEN THE TRANSMISSION MADE A LOUD CLUNK THEN WHINE, AFTER WHICH THE ENGINE REVVED AND I LOST ANY ABILITY TO CHANGE GEARS. AFTER STOPPING THE CAR, I FOUND ONLY THE REVERSE WAS NOT WORKING - THE OTHER GEARS WILL SHIFT OVER 3000 RPM. I HAVE BEEN TOLD IT IS A FAULTY SUNSHELL GEAR IN THE TRANSMISSION. *JB

I HAD SEVERAL INSTANCES OF THE ENGINE REVVING UP BEFORE THE VEHICLE WOULD SHIFT. THESE WERE USUALLY WHEN THE ENGINE WAS COLD SO I ASSUMED THAT WAS THE PROBLEM. HOWEVER 5 DAYS AGO THE TRANSMISSION WENT OUT. THE ENGINE REVVED REALLY LOUD, THE TACH NUMBER WENT WAY UP, SUDDENLY THE VEHICLE CLUNKED & JERKED INTO GEAR IT THEN MADE A WHINING NOISE & WHEN I GOT HOME (DROVE IT REAL SLOW & NOT FAR FROM HOME) THERE WAS NO REVERSE. CHEVROLET SAYS THERE IS NOT A PROBLEM WITH THESE TRANSMISSIONS & THEY HAVE NOT RECEIVED VERY MANY COMPLAINTS ON THIS PROBLEM. MY TRANSMISSION REPAIR SHOP TOLD ME THIS IS THE THIRD ONE IN 3 WEEKS WITH THE EXACT SAME PROBLEM. CHEVROLET IS REFUSING TO DO ANYTHING ABOUT THIS. THERE ARE NUMEROUS WEB SITES FULL OF POSTINGS OF PEOPLE WITH THE SAME PROBLEM. *TR

WINDSHIELD WIPER STOPS WORKING HAS TO BE SHUT OFF AND RESTARTED. HAS BEEN RECALLED BUT CHEVY SAID THE THEY HAVE CLOSED THE CLAIMS ON THIS RECALL #04V046000 AND WILL NOT REPLACE THE MOTOR. *TR
