CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH 4 -WHEEL DRIVE FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 101, NO. 110, NO. 114, NO. 225, NO. 209, & NO. 208. VECHICLES WERE BUILT WITH A LEFT -FRONT BRAKE PIPE WITH A CIRCUMFERENTIAL SCORE AT A RANDOM LOCATION ALONG THE LENGHT OF THE PIPE AS THE RESULT OF THE MANUFACTURING PROCESS. IF THE BRAKE PIPE PARTIALLY OR FULLY FRACTURED,BRAKE PEDAL TRAVEL WOULD IMMEDIATELY INCREASE AND FRONT BRAKE PERFORMANCE WOULD BE REDUCED UNDER CERTAIN CIRCUMSTANCES THE FRONT LOWER CONTROL ARM BRACKETS MAY FRACTURE. MISSING WELDS ON THE REAR FLOW PLAN THE CALIBRATION OF THE TRANSFER CASE CONTROL MODULE COULD CAUSE INSUFFICIENT HIGH SPEED GEAR ENGAGEMENT. THIS FRACTURE COULD RESULT IN SEPARATION OF THE FRONT LOWER CONTROL ARM FROM THE FRAME SOME OF THESE VEHICLES WERE BUILT WITH A RANGE SHIFT COLLAR IN THE TRANSMISSION TRANSFER CASE THAT CONTAINS CRACKS.

AUTOMATIC TRANSMISSION SHIFT CABLE CAME LOSE AND THE CAR COULD NOT BE PLACED IN GEAR. IT WAS STUCK INTO PARK. THE PLASTIC CABLE CONNECTOR TO THE TRANSMISSION CRACKED, WHICH ALLOWED THE BALL TO COME OUT OF THE TRANSMISSION PREVENT THE CAR NOT BEING ABLE TO BE PUT INTO GEAR.

Mileage: 126,000

I STARTED MY VEHICLE AND SHIFTED INTO REVERSE. THE SHIFTER HANDLE MOVED FREELY BUT WOULD NOT ENGAGE IN REVERSE OR DRIVE. MY VEHICLE WAS STUCK IN PARK. LUCKILY, THIS HAPPENED WHEN I WAS IN MY GARAGE AT LUNCHTIME HEADED BACK TO WORK. WHEN I SEARCHED ON THE INTERNET ABOUT WHAT THE PROBLEM COULD BE, I SAW THAT OTHER GM VEHICLES HAD BEEN RECALLED FOR A BROKEN SHIFTER CABLE. WHEN I SPOKE TO THE TOW TRUCK DRIVER AND EXPLAINED MY PROBLEM, HE SAID THAT IT WAS PROBABLY A BROKEN SHIFTER CABLE AND THAT HE HAD TOWED OTHER TRAILBLAZERS FOR THE SAME PROBLEM AND THAT THE VEHICLES HAD BEEN PART OF A RECALL YEARS AGO. I HAD NOT FOUND A RECALL FOR MY PARTICULAR VEHICLE, BUT THAT OTHER GM VEHICLES HAD BEEN RECALLED FOR THAT REASON IS WHY I AM FILING THIS REPORT. I HAVE HAD MY VEHICLE REPAIRED AND WILL UPLOAD THE REPAIR INVOICE.

Mileage: 78,601

I WAS PULLING AWAY FROM A STOP SIGN WHEN MY VEHICLE JUST SHUT OFF. I PRESSED THE BRAKE, PUT MY VEHICLE IN PARK, AND TURNED THE KEY TO THE OFF POSITION. THEN I STARTED MY VEHICLE AS I NORMALLY WOULD, AND IT STARTED UP WITHOUT A PROBLEM. THIS WAS VERY DISCONCERTING AND SCARY. THIS HAPPENED IN A QUIET, RESIDENTIAL AREA, SO THERE WAS NO OTHER TRAFFIC ON THE ROAD AT THE TIME. I INTENDED TO HAVE MY VEHICLE CHECKED, BUT I NEVER DID. THIS WAS SEVERAL YEARS AGO. THE INCIDENT WAS BROUGHT BACK TO MY ATTENTION BECAUSE OF A RECENT BUT DIFFERENT MECHANICAL FAILURE WITH MY VEHICLE. DURING MY INTERNET RESEARCH OF THE OTHER MECHANICAL PROBLEM, I CAME ACROSS RECALL INFORMATION FOR OTHER GM VEHICLES THAT HAD BEEN RECALLED FOR SUDDENLY SHUTTING OFF WHILE IN DRIVE. ALTHOUGH I DID NOT FIND RECALL INFORMATION FOR MY MAKE/MODEL/YEAR, I AM FILING THIS REPORT BECAUSE MY VEHICLE HAS SHUT OFF WHILE IT WAS IN DRIVE. SINCE I DON'T KNOW THE EXACT DATE WHEN THIS OCCURRED, I WILL PLACE AN APPROXIMATE DATE IN THIS REPORT. I WAS "HOUSE SHOPPING" AT THE TIME, SO THE APPROXIMATE DATE WILL BE CLOSE.

WHEN I TURN 4WD ON, THE LIGHT GETS STUCK IN 4WD EVEN WHEN I TRY TO TURN IT OFF. I THINK MY CAR IS STUCK IN 4WD AT THIS POINT. *TR

THREE TIMES SINCE PURCHASING THIS VEHICLE IN JANUARY 2012, I HAVE HAD TO REPLACE THE RIGHT FRONT WHEEL HUB ASSEMBLY DUE TO BEARING FAILURE. RECENTLY THE TRANSMISSION, WHICH HAS NOT EXHIBITED A LEAK, WAS VERY LOW ON FLUID, (3 QUARTS) AND THE FLUID WAS BURNED. THE TRANSMISSION NOW SLIPS AND IS CHANGING ERRATICALLY. THE VEHICLE WAS REGULARLY SERVICED AT BUFF WHELAN CHEVROLET IN STERLING HEIGHTS, MI. *TR

Mileage: 105,000

SHUT CAR OFF AND WHEN I ATTEMPTED TO RESTART KEY WOULD NOT TURN. STEERING WHEEL WAS NOT LOCKED AND IT WOULD NOT SHIFT INTO GEAR. AN HOUR LATER RETURNED TO HAVE IT TOWED AND TRIED THE KEY AND VEHICLE STARTED. *TR

Mileage: 120,000

THIS WAS ACTUALLY THE SECOND OR THIRD INCIDENT WHERE THE KEY GOT STUCK IN THE IGNITION, BLAZER WAS IN PARK THE LIGHTS REMAINED ON SO DID THE RADIO ANYTHING THAT IS TYPICALLY ON DURING AUX, BUT THIS WAS THE BEGINNING OF A LONG PROBLEM THAT LEAD TO ME TRADING OFF..THE KEY GETS STUCK YOU CAN NOT REMOVE IT CAUSED THE BATTERY TO GO BAD, IT WOULD BEGIN TO HAPPEN OFTEN THE SERVICE ENGINE SOON LIGHT WOULD COME ON, THE TRANSMISSION WOULD NOT SHIFT ABOVE 3RD GEAR, ALSO SHORTLY AFTER THE PURCHASE IN SEPT OF 2011 THE SPEEDOMETER STOPPED WORKING. THE BLAZER DIED 3 TIMES GAUGES ON DASH WOULD PERIODICLY STOP WORKING. MY SERVICE 4 WHEEL WOULD COME ON RANDOMLY THE KEY ISSUE WAS THE BIGGEST PROBLEM BUT IT WAS ONLY A MATTER OF TIME BEFORE OTHER THINGS WENT WRONG. WHEN THE KEY WOULD GET STUCK IN THE IGINTION AS STATED THE TRANSMISSION WOULD NOT SHIFT PROPERLY IN THE BEGINNING THE TRANSMISSION WOULD ACT OUT ONCE YOU TOOK IT OUT OF PARK IT WAS NOTICEABLE BUT AS THE PROBLEM BECAME WORSE IT STARTED HAPPENING DRIVING DOWN THE HIGHWAY I NOTICED ONCE THAT I HAVE SUCCESSFULLY MADE IT THROUGH 1-2-3 BUT NEVER GOT OUT OF 3. I SHOULD STATE THAT WHEN THE KEY WAS STUCK I WOULD HAVE TO MANUALLY SHIFT THROUGH THE FIRST AND SECOND THEN PUT IT INTO DRIVE OTHERWISE THE CAR HAD NO POWER BECAUSE IT WOULD BE STUCK IN THE HIGHER GEAR.TRIED TO CONTACT THE DEALERSHIP AS THERE WAS A RECALL ON THE DASH FOR THE 2003 MODEL AND THEY TOLD US IT WASNT A SAFETY PROBLEM I DO NOT UNDERSTAND HOW RANDOM LOSS OF POWER AND RANDOM CAR DYING IS NOT A SAFETY ISSUE, I HAVE BEEN WATCHING THE LIST OF GM RECALLS AND I HAVE NOT SEEN MUCH ABOUT THE TRAILBLAZERS, AND IT BOTHERS ME THAT I AM SURE THERE ARE OTHER ISSUES LIKE THE ONES THAT I HAD. ON ANOTHER NOTE TRANSMISSION RELATED MY NEIGHBORS JUST HAD TO GET RID OF THEIR TRAILBLAZER 2006 FOR TRANSMISSION PROBLEMS. *JS

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 OUT OF THE WAY, SOMEONE COULD GET KILLED. *TR

THE PROBLEMS THAT ARE HAPPENING TO MY 2004 CHEVY TRAILBLAZER : I AM HAVING A WHINING NOISE IN THE FRONT END OF THE VEHICLE AND WHEN I TRY TO ENGAGE INTO 4WD THE SOUND WORSENS AND THERE IS A VIBRATION IN THE FRONT AS WELL THE WHINING ALMOST RESEMBLES A LOW SIREN SOUND. I AM ALSO HAVING A MAJOR MALFUNCTION WITH MY SPEEDOMETER SINCE THE WEATHER HAS GOTTEN COLDER??? I COULD ONLY BE MOVING 10MPH AND IT WILL REGISTER TO 120 OR EVEN SURPASS IT AND THEN GET STUCK, THE ONLY WAY TO UNSTICK IT IS TO SHUT THE CAR OFF AND KEEP RESTARTING IT UNTIL IT RESETS ITSELF BUT NOW IT IS STUCK AND WONT RESET, I WENT ONLINE TO SEE IF THERE WERE ANY RECALLS AND I ALL I FOUND OUT WAS THERE WERE TONS OF PEOPLE HAVING THE SAME ISSUES WITH THEIR TRAILBLAZERS AS I AM HAVING. THESE PROBLEMS ARE OCCURRING AT ALL DIFFERENT TIMES DURING THE LIFE OF THE CAR SOME PEOPLE HAVE THEM HAPPEN AROUND 30,000 MILES OR SOME 50 THOUSAND AND MYSELF THE SPEEDOMETER IS HAPPENING AROUND 72,000 MILES. THE SPEEDOMETER SEEMED TO START TO ACT UP ONCE THE WEATHER WAS COLDER. ITS A SHAME THEY WILL FIX THE LARGER SUV'S DUE TO A LAWSUIT BUT SINCE THIS IS A SMALLER SUV IT'S NOT COVERED. WE HAVE TRIED TO REPLACE THE WHEEL BEARINGS IN THE TRUCK FOR THE FRONT END NOISE TO ONLY FIND THE NOISE DID NOT DISAPPEAR AFTER READING MANY OF OTHER COMPLAINTS FROM OTHERS IT SEEMS THIS COULD BE THE TRANSFER CASE ON THE TRUCK. I AM NOT GOING TO KEEP REPLACING PART AFTER PART TO ONLY FIND OUT ITS THE DRIVE TRAIN AND SOMETHING SHOULD BE DONE ABOUT THIS. *TR

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 THINK THE GOVERNMENT OR SHOULD I SAY WE THE PEOPLE JUST BAILED THIS COMPANY OUT AS FAR AS I'M CONCERNED IF THEY ARE GOING TO MAKE JUNK LET GO BANKRUPT. *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.

Mileage: 101,576

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER. WHILE DRIVING 25 MPH, THE CONTACT HEARD A RUBBING NOISE COMING FROM THE FRONT PASSENGER SIDE OF THE VEHICLE. SHE THEN NOTICED A BURNING ODOR COMING FROM THE ENGINE. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP AND THEY DETERMINED THAT THE OIL CAP FOR THE FOUR-WHEEL DRIVE FAILED. THE CAP WAS REPLACED AT THE COST OF $5 AND THE CONTACT WAS ADVISED TO NEVER PLACE THE VEHICLE INTO FOUR-WHEEL DRIVE. ONE YEAR LATER, WHILE DRIVING AT AN UNKNOWN SPEED, THE CONTACT HEARD A HUMMING NOISE COMING FROM THE FRONT OF THE VEHICLE. SHE WAS ABLE TO SAFELY DRIVE THE VEHICLE TO HER DESTINATION. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP AND THE TECHNICIAN DETERMINED THAT THE FRONT DIFFERENTIAL FAILED. THE REPAIR WOULD COST $2,000. THE VEHICLE HAS NOT YET BEEN REPAIRED. THE CONTACT CALLED THE MANUFACTURER AND WAS INFORMED THAT BECAUSE THE VEHICLE DID NOT RECEIVE REGULAR MAINTENANCE FROM A DEALER, NO COMPENSATION WOULD BE PROVIDED TOWARDS THE REPAIR. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 64,000 AND CURRENT MILEAGE WAS 81,000.

I OWN A 2004 CHEVY TRAILBLAZER WITH 56K MILEAGE. IN DECEMBER 2008, THE SPEEDOMETER STOPPED WORKING. I WOULD BE AT STOP, AND THE NEEDLE SHOWED 80 MPH. I BROUGHT THE CAR TO THE DEALERSHIP RIGHT AWAY AND THEY TOLD ME THAT THE CLUSTER NEEDS TO BE REPLACED - BUT THEY NEEDED TO ORDER THE REPLACEMENT PART. I FINALLY GOT IT FIXED A WEEK LATER AND IT COST ME APPROXIMATELY $525. NOW, FOR THE PAST TWO WEEKS, THE ENGINE HAD SUDDENLY SHUT OFF IN THE MIDDLE OF DRIVING. THE "REDUCED POWER" & "CHECK ENGINE" LIGHTS CAME ON. BOTH TIMES, IT STARTED BACK UP AFTER I PARKED IT, TURNED OFF THE IGNITION, AND RE-STARTED. BUT AFTER THE SECOND TIME, I BROUGHT IT IN TO THE DEALERSHIP. I HAD TO HAVE THE ACCELERATOR PEDAL REPLACED. COST ME APPROX $360. THESE TWO ISSUES ARE VERY CONCERNING WITH ME BECAUSE IF I WERE DRIVING AT HIGHER SPEED (65MPH) IN THE MIDDLE OF THE HIGHWAY (INSTEAD OF 30MPH AROUND TOWN), I COULD HAVE DIED FROM CONTACTS WITH OTHER VEHICLES BECAUSE MY VEHICLES STOPPED FUNCTIONING! *TR

Mileage: 56,000

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.

Mileage: 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 OF GM VEHICLES...BUT WILL BE NO MORE. *TR

Mileage: 45,000

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 ASKED WHY WE WOULD HAVE TO PAY ANYTHING, THEY REFUSED TO ANSWER - JUST TOLD US TO FIGHT IT WITH OUR WARRANTY COMPANY. I'VE BEEN RESEARCHING ONLINE TO FIGURE OUT HOW TO FIGHT THIS AND PREVENT OTHER PEOPLE FROM SUFFERING AS WELL. IF IT'S A GM DEFECT IN THE WAY THE DIP STICK IS POSITIONED, THE CONSUMER SHOULD NOT HAVE TO PAY FOR THE DAMAGE CAUSED BY THE DEFECT. ANY HELP YOU CAN PROVIDE WOULD BE GREATLY APPRECIATED. THE CAR IS A 2004 CHEVY TRAILBLAZER WITH A FULL EXTENDED WARRANTY, BUT IT DOES SPECIFICALLY STATE IT'S VOID IF THE PROBLEM IS DUE TO WATER. AFTER READING ON SEVERAL CHAT ROOMS, THERE SEEMS TO BE MANY PEOPLE WITH THIS SAME ISSUE. *TR

Mileage: 46,000

THE FAILURE INVOLVES THE ELECTRO-MECHANICAL DEVICE THAT SHIFTS THE CAR INTO FOUR-WHEEL DRIVE. THE FOUR-WHEEL IS ENGAGED BY SELECTING 4WD WITH A DASHBOARD SELECTOR SWITCH. THE SWITCH WILL SHOW A LIGHTED INDICATOR MOVING FROM 2WD TO THE 4WD. THIS INDICATION IS FAULTY. WHILE DRIVING TOWARDS A SNOW COVERED MOUNTAIN ROAD WITH SEVERAL SHARP TURNS GOING UP THE MOUNTAIN THE VEHICLES SELECTOR SWITCH WAS MOVED TO THE 4WD POSITION AND THE INDICATOR LIGHT SHOWN IT WAS ENGAGE IN THE 4WD MODE. HOWEVER THE INDICATION WAS FAULTY AND THE VEHICLE WAS ACTUALLY ONLY IN 2WD. THE SELECTOR SWITCH ENGAGES AN ACTUATOR THAT CAUSES A FORK TO MOVE THE GEARS IN THE FRONT TRANSFER CASE INTO OR OUT OF 4WD. THE RESULT OF THE FALSE INDICATION OF THE VEHICLE BEING IN 4WD WHEN IT WAS ACTUALLY IN 2WD CAUSE THE REAR OF THE VEHICLE TO BREAK TRACTION AND THE ENTIRE VEHICLE TO START INTO A SPIN WHICH RESULTED IN THE VEHICLE LEAVING THE ROAD AND DAMAGE TO THE FRONT END OF THE VEHICLE. THE MAIN PROBLEM IS THAT THE VEHICLE GAVE A FALSE INDICATION OF BEING IN 4WD WHEN IT WAS ACTUALLY IN 2WD. *TR

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 ROTAR ASSEMBLY IN THE FRONT PUMP OF THE TRANSMISSION. THIS IS GETTING EXPENSIVE AND FRUSTRATING. ARE THERE ANY OTHER PEOPLE WHO HAVE THE SAME ISSUES OR IS THERE AN ISSUE WITH THE CRANK SHAFT? COULD IT BE THE TRANSMISSION IS BUILT WRONG? THIS IS REDICULOUS!! I HAVE ONLY 70,000 MILES ON IT. WHY WOULD I BUY CHEVY PRODUCTS IF THEY CONTINUE TO FAIL AT SUCH LOW MILES. *AK

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 OF PROBLEMS THEY ARE CAUSING. NEEDLESS TO SAY.. MY WARRANTY IS EXPIRED AND I HAVE TO SHELL OUT $3000 TO REPAIR A 3 YR OLD VEHICLE. *JB

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 TO HAVE THE SAME INCIDENT WITH THE TRANSMISSION SLIPPING, BUT THIS TIME THE ENGINE LIGHT WAS NOT SHOWING. HE TOOK THE VEHICLE TO THE DEALERSHIP ON 12/20/06, AND THEY STATED THAT THERE WASN'T ANYTHING WRONG WITH THE VEHICLE. THE CONTACT CURRENTLY HAS THE VEHICLE PARKED AT HOME AND DOES NOT PLAN TO DRIVE IT BECAUSE HE DOESN'T FEEL SAFE IN VEHICLE. *AK UPDATED 2/26/2007 - *NM

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

I HAVE HAD MY TRAIL BLAZER FOR 1 YR AND 1 MONTH. IN THAT TIME I HAVE HAD TO REPLACE FRONT AND BACK PADS AND ROTORS, BALL JOINTS, CATALYTIC (SP) CONVERTER, AND NOW THEY JUST TOLD ME I HAVE TO REPLACE THE HEAD GASKET ON THE MANIFOLD. WHAT THE HELL IS GOING ON WITH THIS VEHICLE. I NO LONGER FEEL SAFE DRIVING IT. THE OTHER DAY THE RADIO JUST STOPPED PLAYING AND THEN THE SERVICE 4 WHEEL DRIVE LIGHT CAME ON. *NM

THE VEHICLE HAS STALLED OUT 3 TIMES IN THE PAST MONTH. CHECK ENGINE LIGHT CAME ON AND THEN REDUCED ENGINE POWER LIGHT. WE COULD ONLY GO 10 MPH. THANKFULLY WE WERE IN A RESIDENTIAL AREA AND NOT ON THE FREEWAY. DEALERSHIP SAID IT WAS A FAULTY ACCELERATOR POSITION MODULE AND THE PCM NEEDED TO BE REPROGRAMMED. LUCKY US WE ARE OVER IN MILES AND THIS IS NOT COVERED BY THE WARRANTY. *NM

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

THE REAR TIRES ON THE CONSUMER'S 2004 CHEVROLET TRAILBLAZER WEAR OUT EVERY COUPLE THOUSAND MILES WHILE THE FRONT TIRES SHOW NO VISIBLE SIGNS OF WEAR. *NM IT WAS DISCOVERED THAT THE VEHICLE HAD A BENT DIFFERENTIAL. *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

DT: THE CALLER SAID THAT WHEN SHE WOULD BE AT A LIGHT THE VEHICLE WOULD STALL. SHE WOULD HIT THE GAS PEDAL AND THE VEHICLE WOULD HESITATE BEFORE TAKING OFF. ENGINE SERVICE LIGHT CAME ON/OFF. ON JULY 25, 2005 DEALER CHECKED AND REPROGRAMMED AUTOMATIC TRANSMISSION CONTROL MODULE( PCM). ON JULY 29, 2005 DEALER CHECKED AND REPLACED THE PCM AGAIN , AND ON AUGUST 1, 2005 DEALER REPLACED A 02 SENSOR. DEALER SAID THEY COULD KEEP AND DRIVE VEHICLE TO SEE IF THAT FIXED THE PROBLEM . DEALER WOULD NOT GIVE HER A TEMPORARY VEHICLE TO DRIVE WHILE SHE WAITED FOR HER VEHICLE TO BE WORKED ON. DEALER SAID THE 02 SENSOR WAS THE PROBLEM. WOULD NOT OFFER AN EXTENDED WARRANTY. DEALER WILL NOT GIVE HER ENOUGH MONEY FOR IT AS A TRADE IN. *AK

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

THE CHECK ENGINE LIGHT AND THE REDUCED ENGINE POWER LIGHT CAME ON THE FIRST TIME AND THE TRUCK HAD NO ACCELERATION. THERE WAS A CODE RECORDED WHEN SERVICE WAS PERFORMED AND PCM WAS REPROGRAMMED. THE NEXT 3 TIMES THE CHECK ENGINE LIGHT CAME ON AND THE TRUCK WOULD ONLY ACCELERATE IF THE RPM'S REVED UP TO 2, THEN THE TRUCK WOULD MOVE VERY SLOWLY. THE PROBLEM THEY FOUND THIS TIME WAS A FAULTY INGITION SWITCH (2 TIMES) A PROGRAM UPGRADE OF THE MOTHERBOARD OF THE TRUCK, AND THE TORK CONVERTER CLUTCH MODULE. WINDSHIELD WIPER BLADES STOPPED WORKING DURING A SNOW/RAIN STORM.*AK

PURCHASED NEW TRAILBLAZER IN MAY 04. WHEN VEHICLE HAD APPROXIMATELY 3,000 MILES ON IT, I STARTED GETTING A RATTLE OR LOUD BUZZ WHEN ACCELERATING AT APPROXIMATELY 25 PER HOURS JUST BEFORE THE VEHICLE SHIFTS. OCCASIONALLY, THE SHIFT IF JERKY. THE VEHICLE HAS TO BE WARM AND THE RATTLE OR BUZZ FIRST MANIFESTED ITSELF AFTER I TURNED RIGHT AND ACCELERATED FROM A STOP. WHEN WARM, THIS SOUND IS REPEATED ALMOST EVERY TIME I TURN RIGHT AND ACCELERATE. WHEN WARM IS ALSO OCCURS WHEN I JUST ACCELERATE FROM A FULL STOP. OCCASIONALLY, IT WILL ALSO OCCUR AFTER A TIGHT LEFT TURN. I REPORTED IT TO THE DEALER AND THEY TOLD ME THE COMPUTER DID NOT SHOW ANYTHING WRONG. ON THE SECOND TRIP TO THE DEALER I REPORTED IT AGAIN. STILL NO FIX. THE NOISE IS VERY ANNOYING, BUT I CANNOT TELL THAT IT IS DOING DAMAGE. I CERTAINLY WOULD NOT HAVE BOUGHT THIS VEHICLE IF IT MADE THIS NOISE ON THE ROAD TEST. I AM ESTIMATING THE RATTLE OR BUZZ SOUND HAS OCCURRED AT LEAST 75 TIME TO DATE. *NM

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
