2004 Chevrolet Trailblazer Powertrain & Transmission Problems

Electronic throttle body? No throttle control, motor will only idle, turn ignition switch off, then restart it will run. Reduced Engine Power light comes on. Happens for no apparent reason. Very unsafe situation.

ACCELERATING ON IT'S OWN AND IDLING

TRANSMISSION OIL COOLER LINES ARE CORRODED TO THE POINT WHERE THEY ARE LEAKING FLUID AND THE VEHICLE ONLY HAS 130000 MILES ON IT.

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.

AUTOMATIC TRANSMISSION SLIPS WHEN IT TRIES TO SHIFT INTO 3RD OR 4TH GEAR, I READ THAT THERE WAS A REPORT ON THIS HAPPENING BUT THERE WAS NOT A RECALL AS FAR AS I KNOW, I RECENTLY PURCHASED THIS VEHICLE FROM THE ORIGINAL OWNER WHO SAYS THEY NEVER RECEIVED ANY PAPER WORK FROM GM ABOUT DOING REPAIRS. MY QUESTION IS WILL GM REPAIR THIS CONDITION AT NO COST TO ME?

TL* THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER 360. THE CONTACT STATED THAT THE LIGHT FAILED TO ILLUMINATE ON THE GEAR SHIFT MECHANISM AND WAS NOT ABLE TO VIEW WHAT GEAR THE VEHICLE WAS SHIFTED INTO. THE CONTACT ALSO INDICATED THAT THE BATTERY, THE SEAT BELT AND THE BRAKES WARNING LIGHTS RANDOMLY ILLUMINATED AS THE FAILURE PROGRESSED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

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.

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

ENGINE STARTED MISFIRING ON RANDOM CYLINDERS,MISFIRE DOES NOT STAY ON SAME CYLINDERS. HAS DRAMATIC LOSS OF POWER. DIAGNOSTIC CODE SAYS RANDOM MISFIRE. DRAMATICALLY DECREASED FUEL ECONOMY. BAD VIBRATION. SERVICE ENGINE LIGHT FLASHES DURING MISFIRE. DOES NOT HAVE A CONSTANT MISFIRE, IT COMES AND GOES. *TR

DRIVING HOME FROM WORK BRAKES STARTED LOCKING UP DROVE HOME TOOK APART FRONT AN REAR BRAKES FOUND FRONT CALIPERS LOCKED UP CHANGED CALIPERS AN BRAKE PADS FRONT AN REAR TRIED TO BLEED BRAKES HAD A SPONGY PEDAL FILLED MASTER CYLINDER AN NOTICED BRAKE FLUID LEAKING UNDER MASTER CYLINDER CONNECTOR BEHIND FRONT DRIVER SIDE WHEEL NO PART TO FIX NO LISTING . CANNOT DRIVE CAR. THAT'S JUST ONE PROBLEM TRANSMISSION LINES ROTTED AN CHANGED 2 YEARS AGO . POWER STEERING COOLER ROTTED OUT LOST ALL POWER STEERING FLUID 1 MONTH AGO AN PUT AFTER MARKET COOLER IN . ALSO AIR CONDITIONER LINES ROTTED OUT CANNOT HOLD R34 COOLANT ANYMORE. *TR

MY CHEVY TRAILBLAZER 2004 SLOWED DOWN TO 20MPH ON THE HIGHWAY I HAD A VERY HARD AN SCARY TIME PULLING OVER I GOT MY THROTTLE FIXED THAT COST ME 500.00 DOLLARS MY CAR IS STILL DOING THE SAME THING IT WAS DOING ON THE HIGHWAY 20MPH AND AMP IDLES VERY HIGH WONT DROP DOWN TO 0 STAYS AT 20 OR ABOVE THERE SHOULD BE A RECALL NO ONE CAN FIND A PROBLEM WITH MY CAR ALL THEY WANT IS TO KEEP GUESSING WHAT THE PROBLEM IS.I REALLY WOULD LIKE TO NO BECAUSE IT KEEPS GOING BACK TO THE SAME PROBLEM DOESN'T WANT TO GO IN GEAR AND DRIVE IT JUST LET YOU PUT YOUR FOOT ON THE GAS AN DOES NOTHING. *TR

THE TRANSMISSION COOLING LINES CORRODED AND CAUSED A TRANSMISSION FLUID LEAK. THE ENGINE RPMS INCREASED AND THE VEHICLE LOST POWER WHILE GOING DOWN INTERSTATE 86. WHEN THE FLUID LEAKED OUT OF THE TRANSMISSION COOLING LINES, IT SPRAYED ALL OVER THE EXHAUST PIPES, WHICH CAUSED A SEVERE FIRE HAZARD. DUE TO THE LOSS OF TRANSMISSION FLUID, IT CASED SIGNIFICANT DAMAGE TO THE TRANSMISSION INTERNALS. *TR

TRANSMISSION COOLER LINE CORRODED AND BEGAN LEAKING NEXT TO EXHAUST MANIFOLD WHICH COULD HAVE RESULTED IN A FIRE. LINES HAD TO BE REPLACED DUE TO EXCESSIVE CORROSION.

MY RIGHT SIDE BACK DOOR DOES NOT OPEN AND MY LEFT BACK DOOR DOES NOT CLOSE UNLESS I HIT THE LOCK FIRST. ALSO AS I AM DRIVING NO MATTER WHAT THE WEATHER MY 4 WHEEL DRIVE WILL JUST KICK IN ON ITS OWN. NOW IT FEEL AS THOUGH THE TRANSMISSION IS GOING. THIS TO ME IS A DANGER TO MY CHILDREN AND MYSELF> I ALSO FEEL THAT THESE ARE DEFECTS IN THIS VEHICLE AS I FEEL G.M SHOULD BE RESPONSIBLE I WILL NEVER BUY ANOTHER G.M AGAIN. SOMEONE SHOULD LOOK INTO THIS. *TR

LEFT MY HOUSE AT 10:00 AM TO GET MY BLAZER SERVICED, THE SHOP WAS NOT OPEN - I DID MY ROUNDS AND WAS ABOUT FIVE MINUTES FROM MY HOUSE AT A RED LIGHT, PULLED AWAY FROM THE LIGHT AT THE INTERSECTION HEARD A LOUD POP AND BLAZE STALLED. GOOD THING THERE WAS A POLICE OFFICER COMING IN THE OTHER DIRECTION, TOWED TO SHOP AT 12:00 PM WAS TOLD THAT THE FRONT TRANSMISSION WAS BURNT/BLOWN. I WENT FROM NEEDING A TUNE UP TO A MUCH MORE SERIOUS PROBLEM. JUST HAD BLAZE SERVICED 3 MONTHS PRIOR. *TR

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

TRANS LEAK FROM TRANS COOLER LINES. *TR

ABOUT 10 MILES OUTSIDE OF DALLAS MY CHECK ENGINE LIGHT CAME ON BUT NO INITIAL PROBLEMS. LATER THAT NIGHT WHILE DRIVING ON THE INTERSTATE THE CAR WOULD NOT GO FASTER THAN 30MPH. I RETURNED HOME THAT NIGHT AND LEFT IT PARKED. THE NEXT DAY TOOK IT TO AUTOZONE AND THE GUY DID AN ENGINE CHECK STATING THAT MY TRANSMISSION HAS GONE OUT AND THAT IT WAS LOW ON FLUIDS. I ADDED 3 QUARTS OF TRANSMISSION FLUID WHICH SEEMED TO HELP A LITTLE BIT, BUT I DO NOT FEEL COMFORTABLE ENOUGH MAKING AN 8 HR TRIP BACK HOME. *TR

DRIVING NORMALLY ,PUT CAR IN PARK ,PUT CAR BACK IN DRIVE CRUNCHING NOISE ,CAR NO LONGER HAS REVERSE OR 2ND GEAR. *TR
