THE THE COOLANT LINES WERE CLOSE TO THE EXHAUST PIPE MANIFOLD, AND THEY HEATED UP AND CAUSE DAMAGE TO THE COOLANT LINES. THE CONTACT STATED THAT THIS WAS VERY COSTLY, AND SHOULD BE A SAFETY RECALL. THE CURRENT AND FAILURE MILEAGE WERE BOTH 69048.*AK
2002 CHEVROLET BLAZER. CONSUMER WRITES IN REGARDS TO VEHICLE FLEX PLATE ISSUES. *SMD THE CONSUMER STATED THE FLEX PLATE HAD TO BE REPLACED TWICE. THE MANUFACTURER WAS NOTIFIED AND DID NOT OFFER ANY ASSISTANCE. UPDATED 11/27/2017*JS
MY 2002 CHEVY BLAZER WILL NO LONGER SHIFT INTO 4-WHEEL DRIVE. IT HAS BEEN THIS WAY FOR OVER A YEAR NOW, AND CHEVY WON'T EVEN ACKNOWLEDGE MY COMMUNICATIONS ABOUT IT. *TR
WHILE DRIVING, ENGINE CUT OUT. UNABLE TO DRIVE EXCEPT IN THIRD GEAR DESPITE BEING AUTOMATIC TRANSMISSION. OTHERWISE, ENGINE CUTS OUT. *JB
DROVE FROM OHIO TO FLORIDA, 1040 MILES. 250 MILES INTO THE TRIP, MY CONSOLE BECAME EXTREMELY HOT. THE SIDE OF THE CONSOLE TOUCHES THE DRIVERS SEAT AND IT WAS MAKING MY SEAT VERY HOT. THE ITEMS INSIDE MY CONSOLE MELTED, THE HAND WASH BURNT MY HAND WHEN I TOOK IT OUT TO USE IT. NOW THE CONSOLE IS GETTING HOT ONLY AFTER 50 MILES AND SOMETIMES LESS THAN THAT. ALSO, THE CD PLAYER GETS HOT. THE CD'S OCCASIONALLY BECOME SO HOT THAT I DROP THEM WHEN THEY GET SPIT OUT BY THE PLAYER BY ITSELF. I HAVE NO IDEA WHAT THE PROBLEM IS AND I AM WORRIED MY BLAZER MAY CATCH FIRE OR BLOW UP. ALSO, AT TIMES WHEN I START UP AGAIN FROM A RED LIGHT, THE TRANSMISSION SOUNDS SO LOUD LIKE IT IS WORKING VERY HARD TO GET MOVING. I KNOW THESE THINGS ARE NOT NORMAL. AM I SAFE DRIVING MY BLAZER? I BOUGHT IT BRAND NEW IN 2002. NOW I AM AFRAID OF IT. *JB
NO WARNING SIGNS. JUST PUT MY 2002 BLAZER IN REVERSE, HEARD A LOUD POP. WASN'T SURE WHAT HAPPENED, SO I GOT OUT ON THE ROAD AND COULDN'T ACCELERATE FAST ENOUGH UP A HILL AND ALMOST GOT REARENDED BY A CAR GOING 60-65 MPH. PULLED OVER AND FINALLY FIGURED OUT THAT IT WOULDN'T SHIFT OUT OF 2ND AND I HAD NO REVERSE. CALLED LOCAL CHEVY DEALER AND HE IMMEDIATELY KNEW WHAT HAD BROKEN. (SOMETHING CALLED THE SUN SHELL CASING OR SUN GEAR, I THINK). I ONLY HAVE 50K MILES ON THAT CAR AND NOW HAVE BEEN TOLD THEY WONT JUST REPLACE THE PART, THEY HAVE TO REPLACE THE ENTIRE TRANNY.
FRONT WHEEL HUB ASSEMBLY WENT BAD
I HAVE BEEN HEARING A NOISE IN THE FRONT END FOR A FEW WEEKS AND I HAD THE TIRES REPLACED BUT IT DID NOT CURE THE PROBLEM. I HAVE FOUND OUT THAT I NEED A HUB ASSEMBLY WHICH IS $500 FOR THE PART ALONE AND I NEED AN IDLER ARM WHICH I HAVE TAKEN MY VEHICLE IN FAITHFULLY FOR MAINTENANCE TO THE DEALERSHIP AND THEY NEVER TOLD MY ABOUT IT AND JUST SAID TO WATCH THE TIRES. OBVIOUSLY WITH THE WEAR ON MY TIRES (OUTSIDE WEAR) THEY SHOULD OF HAVE KNOWN. I HAVE BEEN IN TWICE FOR THE FRONT END REPLACEMENT OF BUSHINGS AND MANY OTHER THINGS AND I ALSO HAVE HEARD FROM MANY PEOPLE HAVING THE SAME PROBLEM AS I HAVE WITH THE HUB ASSEMBLY. NOT EVERYONE HAS $500 TO JUST FORK OUT. PLEASE HELP. *NM
CONSUMER STARTED THE VEHICLE AND PRESSED THE GAS PEDAL BUT THE VEHICLE DID NOT MOVE. THE CONSUMER APPLIED PRESSURE TO THE ACCELERATOR, AND IT TOOK LITTLE WHILE FOR THE VEHICLE TO START MOVING. THE DEALER INSPECTED THE VEHICLE THREE TIMES AND COULD NOT RESOLVE THE PROBLEM.*AK *CB THE CONSUMER STATED THE TRANSMISSION MADE SOME NOISES, THE DEALER DISCOVERED SOME PARTS OF THE TRANSMISSION WERE DAMAGED, HOWEVER DAYS LATER THE VEHICLE WENT BACK TO NOT ACCELERATING AND THE ENGINE RACING. THE CONSUMER WAS TOLD THAT THE MANUFACTURER WOULD EXTENDED THE WARRANTY ON THE TRANSMISSION. THE BRAKE LIGHT WAS INOPERATIVE THERE WAS A CLICKING NOISE IN THE DRIVERS SEAT.*JB
THE MAXIMUM SPEED WHILE DRIVING THIS VEHICLE IS 40 MPH, ALSO VEHICLE WONT ENGAGE IN REVERSE. DEALER NOT NOTIFIED YET. *AK
CONSUMER WAS HAVING A PROBLEM WITH VEHICLE JUMPING OUT OF GEAR INTO NEUTRAL WHILE DRIVING. THIS HAPPENED ABOUT 8 TIMES. THE CONSUMER TOOK THE VEHICLE TO THE REPAIR SHOP 3 TIMES AND WAS TOLD BY A CHEVROLET REPRESENTATIVE THAT THEY HAD NO ANSWER FOR THIS BEHAVIOR NOR A SOLUTION. THEREFORE, THEY DID NOT KNOW HOW TO REPAIR IT. *AK *SCC *JB
WHILE DRIVING THE VEHICLE, AUTOMATIC TRANSMISSION DOESN'T SHIFT PROPERLY FROM THE FIRST TO SECOND GEAR. DEALER HAS INSPECTED EIGHT TIMES AND WASN'T AVAILABLE TO DUPLICATE OR CORRECT THE PROBLEM. PLEASE PROVIDE ANY FURTHER INFORMATION. *PH
CONSUMER STATES THAT THE TRANSMISSION SLIPS WHEN SLOWING DOWN. DEALER NOTIFIED.*AK
FLUID LEAKED FROM THE VEHICLE, WHICH CAUSED THE TRANSMISSION TO JERK WHEN THE GEARS WERE CHANGED. *JB
THE AUTOMATIC TRANSMISSION FAILED TO SHIFT PROPERLY.*JB
POWER TRAIN-TRANSMISSION IS LOUD AND ALMOST IS SLIPPING WHEN GOING INTO 1ST AND 2ND GEAR OF AUTOMATIC TRANSMISSION. DEALER SAYS OTHERS HAVE SAME COMPLAINT WITH NO FIX AVAILABLE. FAN CLUTCH ENGAGES DUE TO FAULTY SIGNAL FROM SENSOR. ENGINE SOUNDS VERY LOUD WHEN IT ENGAGES. FAN CLUTCH REPLACED ONCE ALREADY BEFORE TAKING DELIVERY OF CAR. ANOTHER DEALER STATES THAT THIS PROBLEM HAS ALSO BEEN PRESENT SINCE 1999 FOR THIS CAR WITH NO FIX AVAILABLE. THERE IS A TSB ON THE TRANSMISSION PROBLEM WITH CAUSE UNKNOWN AND NO AVAILABLE FIX. SEEMS THAT SINCE OTHERS ARE HAVING THIS PROBLEM MANUFACTURER SHOULD BE HELD RESPONSIBLE.*AK
CONSUMER STATES WHILE DRIVING 55MPH A LOUD NOISE OCCURED AND TRANSMISSION WAS SLIPPING. NLM
I HAVE A 2002 BLAZER. SINCE I HAVE OWNED THE VEHICLE IT HAS PERFORMED UNSATISFACTORILY. THE ENGINE RANDOMLY MAKES ROARING NOISE, THE RPMS RISE AND THERE IS CONCOMITANT LOSS OF POWER. I AM TOLD THIS IS NORMAL AND THAT IT IS RELATED TO THE FAN CLUTCH MOTOR AND A SENSOR THAT WORKS ERRATICALLY. THE FAN CLUTCH HAS BEEN REPLACED ONCE AND THE VEHICLE HAS BEEN IN THE SHOP SEVERAL TIMES. I HAVE BEEN INVOLVED IN SEVERAL NEAR MISSES AS THE VEHICLE DOES NOT PERFORM IN A PREDICTABLE MANNER. CHEVROLET REFUSES TO TAKE ANY RESPONSIBILITY FOR THIS ISSUE THOUGH I WAS OFFERED $2000.00 TOWARD THE PURCHASE/LEASE OF ANOTHER VEHICLE. IN REVIEWING THIS WEBSITE I NOTE THAT THERE ARE SEVERAL OTHER COMPLAINTS ABOUT THIS PROBLEM AND IN ALL CASES GM/CHEVROLET HAS REFUSED TO ACCEPT ANY RESPONSIBILITY. IS THERE NOTHING THAT CAN BE DONE FROM A REGULATORY PERSPECTIVE OR DO WE HAVE TO WAIT FOR ANOTHER CORVAIR/PINTO DEBACLE. *NLM
NOT LONG AFTER I PURCHASED MY 2002 BLAZER, I STARTED NOTICING THAT AT RANDOM TIMES THE MOTOR WOULD START RACING WHEN I STARTED THE ENGINE. IT RAN VERY LOUD FOR A PERIOD OF TIME AND THEN WOULD FINALLY SLOW DOWN. WHILE DRIVING THE VEHICLE THIS WOULD ALSO HAPPEN. THE RPMS RAPIDLY INCREASE WHEN ACCELERATING, AND IT WOULD MAKE A LOUD ROARING NOISE, BUT THE VEHICLE DOESN'T GO ANY FASTER. I TOOK IT IN TO THE SHOP AND WAS TOLD THIS WAS NORMAL, THAT IT WAS THE CLUTCH FAN. IT IS EXTREMELY HARD TO BELIEVE THAT THIS IS NORMAL FOR A NEW VEHICLE. I HAVE HAD THE BLAZER SINCE APRIL OF 2002 AND IT CONTINUES TO DO THIS AND HAS SOMETIMES PUT ME IN VERY UNSAFE POSITIONS. THIS PROBLEM SEEMS TO ME TO BE MORE OF A TRANSMISSION PROBLEM THAN A FAN. I HAVE ALSO HAD PROBLEMS WITH THE FUEL GAUGE. IT WILL SHOW EMPTY WHEN IT HAS PLENTY OF GAS. IT HAS SHOWED LOW ON FUEL, AND THEN WHEN I STOP TO GET FUEL, IT WILL NOT TAKE ANY GAS. BUT THEN I HAVE RUN OUT OF GAS RIGHT AFTER TRYING TO PUT SOME IN THE TANK. THE THIRD PROBLEM IS THE LEFT FRONT DOOR HINGE. THE PIN CONTINUOUSLY WORKS OUT OF POSITION AND IT FEELS LIKE THE DOOR IS ABOUT TO FALL OFF AND IT DOESN'T CLOSE PROPERLY AND I HAVE TO HAVE THE PIN KNOCKED BACK INTO POSITION. ALSO, AT THE TIME I PURCHASED THE VEHICLE, IT HAD A CASSETTE PLAYER AND THE DEALERSHIP AGREED TO INSTALL A CD PLAYER AS PART OF THE PURCHASE AGREEMENT. THE VEHICLE ALSO HAD OPTIONAL CONTROLS ON THE STEERING WHEEL. WHEN THEY INSTALLED THE CD PLAYER, THE CONTROLS ON THE STEERING WHEEL NO LONGER WORKED. WHEN I ASKED THEM ABOUT THIS, THEY JUST SAID THAT THIS CD PLAYER COULD NOT BE CONTROLLED FROM THE STEERING WHEEL CONTOLS AND LEFT IT AT THAT. I THINK THEY SHOULD HAVE INSTALLED ONE THAT COULD HAVE FUNCTIONED THE SAME AS THE FACTORY INSTALLED EQUIPMENT.
ON 12-10 I REPORTED LIGHTS ON TRANSFER CASE DISPLAY FLICKERED. ADVISED NEEDED UPDATED TRANSFER CASE SWITCH. WAS ADVISED OK TO DRIVE VEHICLE. ON JANUARY 7 DIALED SELECTOR TO 4WD BECAUSE OF SNOWY WEATHER TO GET OUT OF MY DRIVEWAY. STARTED UP DRIVEWAY--FISHTAILED. 4 WD WOULD NOT ENGAGE. DEALER ADVISED, RETURNED VEHICLE TO DEALER EVENING OF JANUARY 7. ADVISED TODAY, NEW PART UNAVAILABLE. TRANSFERRING FROM DEMO MODEL IN STOCK. HOW CAN A SITUATION LIKE THIS EXIST? ESPECIALLY WITH NO NOTIFICATION OR RECALL?*AK
