SOME WITH LESS MILES AND SOME WITH MORE...I CAN NOT AFFORD TO PAY 3000 DOLLARS FOR A FAULTY TRANSMISSION WHEN IT IS OBVIOUS IT IS SOMETHING TO DO WITH GM TRANSMISSIONS....AN INVESTIGATION NEEDS TO BE DONE I AM A HUSBAND A FATHER AND BOTH ME AND MY WIFE WORK FULL TIME BUT WE CAN NOT AFFORD THIS AS MANY OTHER PEOPLE CANT AND CHEVY WILL NOT STICK UP FOR THEIR VEHICLES,,,RECALLS MUST BE DONE SO THE WORKING CLASS CAN SURVIVE WITHOUT THIS VEHICLE I WILL LOSE MY JOB AND GM WILL GET RICHER AND RICHER TO BAD THEY DON'T MAKE CARS LIKE THEY USE TOO...ALL I DID WAS GET IN MY CAR START IT...

LAST SUMMER, MY VEHICLE STARTED STUMBLING AT SPEEDS GREATER THAN 50MPH ON THE HIGHWAY. I HAD MY VEHICLE SERVICED SEVERAL TIMES, WITHOUT THE ISSUE BEING RESOLVED. I HAVE HAD THE THROTTLE BODY REPLACED, TUNE-UP, MAP SENSOR, AIR INTAKE SENSOR, FUEL SYSTEM CLEANED, FAN CLUTCH REPLACED, STILL HAD THE STUMBLING PROBLEM. APPROXIMATELY 2 WEEKS AGO I WAS DRIVING HOME ON THE HIGHWAY, WHEN I HEARD THE ENGINE REV UP VERY HIGH, BUT I WASN'T GOING ANY FASTER. I THEN PRESSED ON THE GAS, THE ENGINE RACED, BUT I WAS JUST COASTING. I WAS ABLE TO COAST OFF THE HIGHWAY TO THE MEDIAN, THANK GOD NOBODY WAS BEHIND ME. I ALSO THANK GOD I DIDN'T HAVE MY FAMILY WITH ME. THE MECHANIC SAID, THAT ONE OF THE GEARS INSIDE, THE TRANNY WAS BROKEN, AND THE PUMP HAD SHATTERED. I WOULD HATE TO SEE THIS HAPPEN TO SOMEONE, AND THEY CAN NOT GET...

I HAVE A 2004 CHEVROLET TRAILBLAZER SUV 4WD WITH 61000 MILES ON IT AND HAVE LOST REVERSE ON IT. MY MECHANIC TOOK IT APART AND FOUND SOME PIECES HAD BROKE AND IT WILL HAVE TO BE REBUILT OR REPLACED. AFTER READING ABOUT OTHER COMPLAINTS WITH PEOPLE HAVING THE SAME PROBLEM I WOULD HAVE TO SAY IT IS THE SUN GEAR. I'M VERY UNHAPPY TO HEAR THAT GM DOESN'T ADMIT TO HAVING A PROBLEM WITH THIS TRANSMISSION,BUT IT IS OBVIOUS TO ME THAT THERE IS A PROBLEM THAT NEEDS TO BE ADDRESSED. *TR

I WAS DRIVING IN TRAFFIC AND MY TRUCK WOULD NOT ACCELERATE OR CHANGE GEARS AT ALL. THIS WAS DURING JULY 4TH OF THIS YR. I HAD JUST HAD IT SERVICED. I HAD THERE TRANSMISSION SERVICED AND WAS OK UNTIL AUG 29TH. IT HAPPENED WHILE I WAS ON THE INTERSTATE. *TR

I HAVE TRANSMISSION PROBLEMS WITH MY 2004 TRAIL BLAZER I FIRST NOTICED IT WHEN I WAS DRIVING DOWN THE ROAD AT 55 AND ALL THE SUDDEN IT WAS LIKE THE VEHICLE WAS PUT IN NEUTRAL AND I PULLED TO THE SIDE SHUT THE VEHICLE OFF AND TRIED TO START AGAIN AND IT TOOK OFF FINE LIKE NOTHING WAS WRONG. THEN A DAY OR 2 LATER THE SAME THING HAPPENED SO I HAD IT TOWED TO THE GARAGE. THEY TOLD ME MY TRANSMISSION WAS BAD I WAS SHOCKED WITH ONLY 58,000 ON THE VEHICLE THEY SHOWED ME THE DIPSTICK WAS RUSTED RIGHT OFF AND ASKED ME WHAT HAPPENED I THEN ASKED THEM WHAT HAPPENED. SO LONG STORY SHORT THEY WANTED TO CHARGE $3000 TO REPLACE BECAUSE THE WARRANTY RAN OUT AT 36,000 I REFUSE TO PAY WHEN THERE SHOULD BE A RECALL FOR A PROBLEM THEY ADMIT THEY HAVE. AND TO...

THE SPEEDOMETER QUIT WORKING ON MY 2004 CHEVY TRAILBLAZER ABOUT 9 MONTHS AGO. TACH ALSO HAS A TENDENCY TO STICK. TRANSMISSION STARTED GOING OUT 2 WEEKS AFTER PURCHASE (USED IN JULY 2008 WITH 42,000 MILES). TRANSMISSION WENT COMPLETELY OUT IN NOVEMBER 2008. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE TRANSMISSION SUN GEAR WAS FAULTY. AN ELECTRICAL COMPONENT WAS BURNING INSIDE THE VEHICLE, ALONG WITH ABS FAILURE. THE VEHICLE WAS TAKEN BACK TO THE DEALER AND THEY STATED THAT THERE WAS NO GUARANTEE THAT THE VEHICLE WAS WORKING PROPERLY. THE OIL NEEDED TO BE CHANGED, SO THE CONTACT CHANGED IT HIMSELF. THE FAILURES OCCURRED RIGHT AFTER THE VEHICLE WAS PURCHASED FROM THE DEALER. THE DEALER PERFORMED A 120 POINT INSPECTION, BUT THEY NEVER REPAIRED THE VEHICLE. THE FAILURE MILEAGE WAS 101,576.

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. THE CONTACT TOOK THE VEHICLE TO MIDAS FOR PREVENTIVE MAINTENANCE. THE TRANSMISSION WAS FLUSHED AND THE OIL WAS REPLACED WITH A LIFE X-TEND OIL, WHICH CAUSED THE TRANSMISSION TO SLIP AND MAKE A LOUD NOISE WHEN SHIFITNG INTO REVERSE OR DRIVE. THE DEALER STATED THAT THE BEARING FAILED. THE CONTACT FEELS THAT THE OIL THAT WAS PLACED IN THE TRANSMISSION REVEALED THAT THE TRANSMISSION HAD PREVIOUS FAILURES. A REPORT WAS FILED WITH THE MANUFACTURER. THE MANUFACTURER STATED THAT THEY WILL INVESTIGATE THE FAILURE. THE X-TEND OIL MANUFACTURER STATED THAT THEY WOULD PAY FOR THE REPAIR IF IT IS PROVEN THAT THE OIL WAS THE CAUSE FOR THE TRANSMISSION FAILURE. THE CURRENT AND FAILURE MILEAGES WERE 102,000.

BOTH ISSUES OCCUR DAILY: APPARENT TRANSMISSION PROBLEMS...VEHICLE CANNOT SEEM TO "GET IN GEAR" WHEN CRUISING ANYWHERE FROM 40 - 70 MPH. IT BOUNCES BACK AND FORTH BETWEEN GEARS - NOT NORMAL DRIVING CONDITIONS. MULTIPLE TRIPS TO 2 DIFFERENT GM DEALERS HAS EXPOSED NO PROBLEMS, AS THEY "CANNOT REPLICATE THE PROBLEM". THEY MUST NOT HAVE DRIVEN THE CAR AT THOSE SPEEDS AS IT DOES IT RELIGIOUSLY. LIKE MANY OTHER COMPLAINTS LISTED HERE, AND THROUGHOUT SEARCHES DONE FOR 2004 TRAILBLAZER ISSUES, MY TACHOMETER & SPEEDOMETER ARE FAULTY. THEY DO NOT WORK PROPERLY... AT ANY TIME MAY SHOW 8000 RPMS OR 100+ MPH WHEN SITTING AT A STOPLIGHT, OR RESTING AT 0 RPMS AND 0 MPH WHEN CRUISING ON A HIGHWAY. THIS IS DANGEROUS, AND GM NEEDS TO FIX THIS PROBLEM ASAP FOR MODELS EXPERIENCING THIS ISSUE. I'M VERY DISAPPOINTED THERE HAS NOT BEEN A RECALL - MY FAMILY HAS ALWAYS BEEN OWNERS...

WE TOOK OUR CAR ON WEDNESDAY 5/14 TO SUPERIOR CHEVROLET IN CINCINNATI OH BECAUSE ON TUESDAY EVENING THE TRANSMISSION FELT LIKE IT WAS STARTING TO SLIP AND NOT DRIVING CORRECTLY. THE DEALERSHIP CONTACTED US ON THURSDAY 5/15 TO SAY THEY WERE WAITING FOR THE WARRANTY REPRESENTATIVE TO COME OUT AND GIVE APPROVAL BEFORE IT COULD BE REPAIRED. ON FRIDAY AFTERNOON, WE WERE ADVISED THE CLAIM WAS DENIED BECAUSE THERE WAS WATER IN THE TRANSMISSION. THE SERVICE MANAGER SAID IT WAS DUE TO A GM DEFECT WITH THE DIP STICK - THE WAY IT WAS POSITIONED ALLOWED WATER TO GET INTO THE TRANSMISSION AND RUST, SO THE WARRANTY WAS NULL AND VOID. THE SERVICE MANAGER SAID HE SPOKE W/HIS GM REP AND THEY WOULD AGREE TO "DO US A FAVOR" AND SPLIT THE COST OF THE NEW TRANSMISSION - $1200 STILL OUT OF POCKET FOR US. WHEN WE PUSHED BACK AND...

IN APRIL 2007, THE '04 TRAILBLAZER'S TRANSMISSION FAILED. AT THE TIME THE VEHICLE HAD LESS THAN 50,000 MILES. I DRIVE THE CAR VERY WELL - MOSTLY HIGHWAY MILES AS I COMMUTE FOR WORK - AND THE VEHICLE HAD NEVER BEEN USED TO TOW. THE TRANSMISSION WAS REPAIRED AT A CHEVROLET DEALER, AND LESS THAN 2 MONTHS LATER, THE TRANSMISSION FAILED AGAIN. I AM VERY UNSATISFIED WITH THE QUALITY OF THIS VEHICLE.*AK

I HAVE A 2004 TRAILBLAZER. I HAD TAKEN IT TO THE DEALERSHIP SERVICE CENTER ON SEVERAL OCCASIONS BECAUSE OF ISSUES WITH IT. THE SERVICE ENGINE LIGHT CAME ON ALL THE TIME. IT WOULD REV UP THE RPMS FOR NO REASON AND MAKE A WEIRD SOUND. IT WOULD NOT GO INTO 4 -WHEEL DRIVE OR OUT OF IT LIKE IT IS SUPPOSED TO. AND OTHER THINGS. I HAD IT CHECKED, AND THEY SAID IT WAS ALL FINE AND THEY COULDNT DUPLICATE THE ERRORS. HOWEVER, SUBSEQUENTLY, THE TRANSMISSION HAS GONE OUT 4 TIMES IN THE LAST 4 MONTHS. I HAVE HAD IT REPLACED 3 TIMES. IT IS NOW AT THE TRANSMISSION SHOP AND THEY STATE THAT THERE IS A PROBLEM WITH THE ENGINE HAS TOO MUCH TRAVEL TO IT FRONT TO REAR. THE CRANK SHAFT SPECIFICALLY WHICH IS ALLOWING THE TORQUE CONVERTER TO PULL AWAY FROM THE FRONT PUMP AND BREAK THE...

WE BOUGHT A 2004 CHEVY TRAILBLAZER BRAND NEW. WE HAD ALL SCHEDULED MAINTENANCE PERFORMED. THEN IN DECEMBER 29TH OF 2006 IN THE EVENING WE EXPERIENCED A LOSS OF THE TRANSMISSION IN THIRD GEAR. WE WERE TRYING TO MERGE ONTO A HIGHWAY AND WERE ALMOST REAR ENDED BY A SEMI-TRACTOR TRAILER TRUCK. I QUICKLY PULLED OFF TO THE BREAK DOWN LANE TO AVERT AN ACCIDENT. IT HAS BEEN ROUGHLY BEEN SIX WEEKS SINCE WE DROPPED THE VEHICLE OFF AT A AUTHORIZED CHEVY DEALER. OUR EXTENDED WARRANTY WANTS TO REBUILD THE TRANSMISSION. THE CHEVY SERVICE DEPARTMENT WANTS TO REPLACE IT. THEY ARE AT A STALEMATE. THIS VEHICLE HAD ONLY 68000 MILES ON IT. *JB

WE BOUGHT OUR 04 TRAILBLAZER USED ABOUT A YEAR AND A HALF AGO. IT WAS OWNED BY ENTERPRISE BEFORE AND THEREFORE ALREADY HAD 30000 MILES ON IT BUT WE KNEW THAT IT WAS MAINTAINED WELL. IT IS NOW AT 71000 MILES AND WE HAVE DONE ALL RECOMMENDED MAINTENANCE. YESTERDAY, WHILE ON THE INTERSTATE THE TRANSMISSION LOST THIRD GEAR AND ABOVE. THIS WAS DANGEROUS BUT LUCKILY I GOT OFF OF THE INTERSTATE WITH NO INCIDENCE. THIS MORNING WE TOOK THE TRUCK TO OUR LOCAL AND TRUSTED MECHANIC WHO DETERMINED THAT THE TRANSMISSION WAS SHOT. HE CALLED JASPER TO GET A PRICE ON A NEW TRANSMISSION AND DURING THAT CONVERSATION, JASPER INFORMED HIM THAT THEY HAVE DONE 15 UPGRADES TO THIS PARTICULAR GM TRANSMISSION AND THAT EVEN GM IS BUYING REPLACEMENT TRANSMISSIONS FROM THEM. I THINK THAT GM SHOULD CONSIDER SOME TYPE OF RECALL ON THE TRANSMISSIONS DUE TO THE OBVIOUS AMOUNT...

TL* - SOMETIME IN LATE SEPTEMBER 2006, WHILE DRIVING AT 65 MPH THE TRANSMISSION BEGAN TO SLIP. THE VEHICLE SOUNDED AS IF IT WANTED TO ACCELERATE, BUT COULDN'T. THE CONTACT'S VEHICLE CONTINUED TO HAVE THE FAILURE FOR ABOUT 10 SECONDS. THE VEHICLE ALSO HAD THE SAME TYPE OF FAILURE WHILE AT A STOP LIGHT. WHILE TRYING TO ACCELERATE THE VEHICLE'S SPEED DECREASED TO 5 MPH FOR ABOUT 20-30 SECONDS. ON 10/11/06 CONTACT TOOK THE VEHICLE TO THE DEALERSHIP. DEALERSHIP REPLACED THE EXHAUST CHECK VALVE. ON 10/17/06 VEHICLE CONTINUED TO HAVE THE SAME FAILURE AND THE ENGINE LIGHT WAS TURNING ON,. THE CONTACT TOOK THE VEHICLE TO THE DEALERSHIP WHERE THEY REPLACED THE OXYGEN SENSOR. THE CONTACT CONTINUED TO HAVE THE SAME INCIDENT WITH THE TRANSMISSION SLIPPING AND THE CHECK ENGINE LIGHT COMING ON. CONTACT TOOK THE VEHICLE TO THE DEALERSHIP ON 10/3106, AND THEY REPLACED THE VALVE BODY. IT CONTINUED...

WHILE I'M DRIVING THE CAR WILL JUST TURN OFF. I CAN BE AT A LIGHT, TURNING, MERGING ONTO TRAFFIC OR JUST SITTING IN TRAFFIC. I'VE BEEN ABLE TO AVOID THREE ACCIDENT TO DATE. I DID BRING THE CAR IN TO THE DEALER - THEY FIXED IT. UNTIL IT HAPPENED THREE DAYS LATER. IT HAPPENS 6 OUT OF THE 7 DAYS A WEEK. *JB

TRANSMISSION WENT OUT. *JB

I OWN A 2004 CHEVROLET TRAILBLAZER AND THE TRANSMISSION RECENTLY FAILED, DUE TO CAUSES UNKNOWN. THIS CONCERNS ME BECAUSE I ONLY HAVE 54,000 MILES ON MY VEHICLE AND IT HAS RECEIVED ALL SCHEDULED MAINTENANCE. ALSO I'VE DONE SOME RESEARCH TO FIND OUT THAT IS A RECURRING ISSUE STARTING IN 2002 WITH THE TRAILBLAZER. I AM GOING TO CONTACT CHEVROLET FOR REPAIR BUT MY WARRANTY IS EXPIRED AND I AM SURE IS WILL HAVE TO PAY FOR ALL REPAIRS. *JB

TRANSMISSION SLIPS WHEN ACCELERATING SUCH AS MERGING ONTO A HIGHWAY. HAS OCCURRED AT LEAST 10 TIMES. HAS BEEN TO DEALER 3 TIMES BUT SAY THEY CANNOT FIND A PROBLEM IF CHECK ENGINE LIGHT DOES NOT COME ON. HAS HAPPENED INTERMITTENTLY OVER A YEAR - VEHICLE HAS ONLY 27,000 ON IT. *JB

SHORTLY AFTER I PURCHASED A 2004 CHEVY TRAILBLAZER I BEGAN TO HAVE PROBLEMS WITH A LOUD VIBRATION FROM THE UNDERCARRIAGE. IT HAS BEEN TO THE SHOP NUMEROUS TIMES BUT IS STILL NOT FIXED. RECENTLY THE VEHICLE BEGAN STALLING OUT AT ANY GIVEN TIME. DEALER COULD NOT REPLICATE. STILL DOES IT!!! AROUND THE SAME TIME MY TRANSMISSION WOULD SLIP. DEALER COULD NOT REPLICATE. STILL DOES IT!!! NOW I AM FEELING A LOT OF VIBRATION IN THE STEERING WHEEL WHEN I TURN. TALKED TO OTHER TB OWNERS AND I THINKING I WILL NEED TO REPLACE THE STRUTS. WHAT NEXT!! *NM

2004 CHEVROLET TRAILBLAZER (V6). VEHICLE SUDDENLY SHIFTS ITSELF INTO 4 WHEEL DRIVE LOW GEAR WITHOUT WARNING AND WITHOUT ANY ACTION BY THE DRIVER. VEHICLE WAS BROUGHT TO AUTHORIZED REPAIR CENTER AND DISMISSED AS DRIVER ERROR. SHIFTING ANY VEHICLE INTO 4 WD LOW REQUIRES A DEFINITIVE ACTION BY THE DRIVER OF THE VEHICLE. AN ACTION THAT THE DRIVER WOULD KNOW THEY PERFORMED. THIS IS THE 3RD SUCH INCIDENT WITH GM VEHICLES MY COMPANY HAS HAD. ALL DISMISSED AS DRIVER ERROR. INVESTIGATIVE ACTION NEEDS TO BE TAKEN AT SOME LEVEL. OUR LOCAL DEALERS AND REPAIR CENTERS DON'T SEEM TO BE CONCERNED. *NM

THE VEHICLE SWITCHES FROM 2WD TO AWD ON ITS OWN. THIS CAUSES THE VEHICLE TO KLUNK AND BUCK. IT ALMOST FEELS LIKE SOMEONE IS HITTING THE VEHICLE FOM BEHIND. THIS HAPPENED SEVERAL TIMES BEFORE WE FIGURED OUT WHAT THE PROBLEM WAS. VEHICLE WAS REPAIRED AT THE DEALERSHIP. THIS WAS ONLY ONE OF TWENTY-ONE FAILURES I HAVE EXPERIENCED WITH THIS VEHICLE SINCE I PURCHASED IT IN MAY OF 2004- NOT TO MENTION MY SEVERE BACK PAIN THAT IS CAUSED FROM THE DRIVER'S SEAT. I HAVE OWNED 9 VEHICLES, AND HAVE NEVER WITNESSED SUCH POOR QUALITY IN A AUTOMOBILE. I AM SEEKING A BUY-BACK FROM GM.*AK

WHEN ACCELERATING FROM A STOP DRIVE TRAIN HESITATES AND ENGINE COMES TO A NEAR STALL, AND THEN ACCELERATES. THIS DOES NOT OCCUR ON EVERY START, RANDOMLY. TOOK VEHICLE INTO DEALER WHO STATED THAT IT WAS NORMAL FOR THE TYPE OF DRIVE TRAIN . THEN THE DEALER REPROGRAMMED THE VEHICLE. AFTER ONE DAY OF DRIVING THE PROBLEM HAS BEGUN AGAIN. THIS HESITATION IS VERY DANGEROUS CROSSING TRAFFIC AND IN INTERSECTIONS.*AK

CAR HAS A VIBRATION WHEN THE SPEED IS HELD CONSTANT. BEEN TO THE DEALER TWICE, THEY FOUND THAT ALL FOR TIRES WERE OUT OF BALANCE. PROBLEM STILL THERE, GAVE ONE TECH RIDE BECAUSE THEY COULD NOT REPLICATE, HE SAID IT WAS UNUSAL BUT HE WAS FRONT END GUY, SECOND TECH AND SERVICE MANAGER SAID IT WAS NORMAL, NOT SURE IF THEY WERE ABLE TO REPLICATE. WAS TOLD TO BRING IT BACK WHEN PROBLEM GOT WORSE OR BROKE. *AK
