I OWN A 2003 CHEVROLET TRAILBLAZER EXT. I SMELLED A STRONG ODOR OF GAS EMANATING FROM MY VEHICLE RECENTLY. AFTER SOME INVESTIGATING, I DISCOVERED THAT THERE WAS FUEL LEAKING OUT OF THE TOP OF MY FUEL TANK ONLY WHILE THE ENGINE WAS RUNNING. I DROPPED THE FUEL TANK AND DISCOVERED THAT THE METAL NIPPLES FROM THE TOP OF THE FUEL PUMP THAT CONNECT THE FUEL LINES TO THE FUEL PUMP WERE COMPLETELY RUSTED AND WHEN THE VEHICLE WAS RUNNING, FUEL WAS JETTING ALL OVER THE UNDER CARRIAGE OF MY VEHICLE. THE METAL RING THAT HOLDS THE FUEL PUMP TO THE TANK WA…

HAVE HAD MY 2003 TRAILBLAZER LT 2WD V8 IN THE SHOP UNDER WARRANTY MANY TIMES. FIRST WAS A RECALL ON THE DRIVE SHAFT WHICH WAS REPLACED 3 TIMES. STILL HAVE A NOISE THE DEALED SAYS THEY DON'T HEAR! NEXT CAME THE TAILLIGHT RECALL. NOW I HAVE A RECURRING PROBLEM WITH A DEAD BATTERY. THIS DOESN'T HAPPEN ALL THE TIME AND NOTHING HAS BEEN LEFT ON TO CAUSE IT. I CAN GO INTO A STORE AND COME OUT TO FIND IT DEAD. WHEN YOU CHARGE THE BATTERY, THEN EITHER THE HEATED SEATS WORK IMPROPERLY, THE BLOWER WON'T COME ON, SOMETHING DIFFERENT EVERY TIME. *JB…

5 MONTHS AFTER I PURCHASED MY 2003 CHEVY TRAILBLAZER I WENT OUT TO START THE CAR AND IT WOULD NOT START. I TOOK THE CAR TO THE DEALER THE FIRST TIME FOR THIS PROBLEM AND VARIOUS OTHERS AND WAS TOLD THEY COULD NOT REPLICATE THE PROBLEM. I REPLACED THE BATTERY AND THE CAR WORKED FOR APPROXIMATELY ANOTHER 5 MONTHS AND THE SAME OCCURRED. ON BOTH OCCASIONS THE KEY WAS LOCKED IN THE IGNITION AND ATTEMPTS AT JUMP STARTING THE VEHICLE FAILED MULTIPLE TIMES. SINCE THE SECOND TIME HAPPENED THIS MORNING I HAVE YET TO TAKE IT TO THE DEALER. THIS CAR…

THE BRAKES O MY 2003 EXT. TRAILBLAZER ARE MUSHY. WHEN STOPPED IN TRAFFIC AND CONSTANT PRESSURE IS HELD ON THE BRAKE PEDAL THE PEDAL CONTINUES TO GO TOWARD THE FLOOR. I WAS SHOWN ANOTHER EXT. TRAILBLAZER AT THE DEALERS THAT HAD BRAKES ACTING THE SAME WAY AND I WAS TOLD IT IS NORMAL. I HAVE HAD SEVERAL SUV'S AND NEVER EXPERIENCED THIS TYPE OF BRAKE PERFORMANCE BEFORE. IN CLOSE TRAFFIC, I HAVE PUT THE TRANSMISSION IN PARK DUE TO THE FEELING THAT I AM GOING TO RUN OUT OF PEDAL TRAVEL.

WITHOUT ANY SQUEALING IN THE DAYS AND WEEKS BEFORE THE BRAKE FAILURE, AS I WOULD EXPECT FROM DETERIORATING BRAKES, THE BRAKES ON MY 2003 TRAILBLAZER EXT FAILED. FORTUNATELY, THE METAL TO METAL SOUND HEARD ON FEB. 4, 2005, ALERTED MY WIFE TO CALL OUR LOCAL CHEVY SERVICE CENTER. AT THE TIME OF THE FAILURE, THIS CAR HAD 29,000 MILES ON IT. NOT ONLY DID THE DEALER FIND THE LEFT FRONT BRAKE DIGGING INTO THE ROTOR SURFACE, BUT THEY FOUND THE REAR BRAKES WORN LOW AND THE EMERGENCY BRAKE PORTION OF THE ROTOR ROTTED. AT 29,000 MILES, TOTAL BRAKE OVERHAU…

WHEN USING KEYLESS ENTRY THE MIRRORS ALSO TURN TO THE GROUND. THE MIRROR IS CHANGING BY ITSELF, AND IT IS NOT GOING BACK TO THE CORRECT SETTING. THE MIRROR IS ALWAYS MAKING A CLICKING NOISE AND IT IS FACING DOWNWARD. THERE IS NO PROBLEM WITH THE RIGHT SIDE. THE DEALER REPLACED THE RIGHT SIDE MIRROR, AND FROM THEN ON THE LEFT SIDE HAS NOT WORKED. CONSUMER HAS TAKEN …
