2004 Chevrolet Trailblazer power train 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.”

“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.”

“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.”
