I STARTED NOTICING THAT MY GAS NEEDLE WOULD FLOAT AFTER FILLING THE GAS TANK ON TWO OCCASIONS. THE FIRST TIME I STOPPED ONE DAY TO FILL THE GAS TANK THINKING I WAS ON EMPTY. AS I PULLED OFF THE NEEDLE WENT TO E AGAIN AFTER STOPPING ON FULL BEFORE I TURNED ON THE ENGINE. A GENTLEMAN AT THE GAS STATION KNEW WHAT WAS GOING ON WITH MY CAR AS HE WAS DRIVING A CHEVROLET PICKUP AND SAID IT WAS A COMMON THING WITH CHEVROLETS. HE ALSO TOLD ME THE PROBLEM WAS WITH THE GAS GAUGE WIRE. I CALLED TO MAKE AN APPOINTMENT WITH SERVICE DEPARTMENT TO FIND OUT THAT NO RECALLS WERE MADE REGARDING THIS ISSUE. IF IT WAS A COMMON PROBLEM IN CHEVROLETS THEN WHY WAS THIS NOT A RECALL OR A SAFETY ISSUE..I WOULD ASSUME IF SOMEONE WOULD DRIVE AND EXPERIENCE WHAT I WAS EXPERIENCING WITH THE FLOATING NEEDLE OR WORSE RUN OUT OF GAS UNAWARE THAT THE NEEDLE WAS NOT REGISTERING PROPERLY WHILE DRIVING . DISCUSSING THE SAME PROBLEM I WAS EXPERIENCING WITH A FRIEND AND SHE INDICATE TO ME THAT A COWORKER WAS HAVING THE SAME PROBLEM.. THE SECOND TIMEI HAVE RAN OUT OF GAS WAS WHILE TRAVELLING IN HIGH RUSH HOUR TRAFFIC DUE TO THE NEEDLE NOT WORKING PROPERLY. CHEVROLET SHOULD TAKE CARE OF THIS DANGEROUS ISSUE WITH ITS CUSTOMERS. A RECALL SHOULD BE MADE BEFORE SOMETHING TERRIBLE OCCURS. I KEEP TRACK OF MY MILEAGE AS I DID NOT BELIEVE THIS WAS AN ISSUE I SHOULD HAVE TO PAY TO FIX. THIS APPEARED TO BE A COMMON PROBLEM FOR THIS MANUFACTURER. *AK

ON SEPTEMBER 28TH 2006 I WAS DRIVING MY 2005 CHEVY TRAILBLAZER EXT DOWN THE ROAD BETWEEN 55 AND 60 MPH. IT HAD STARTED RAINING ABOUT 5 MINUTES EARLIER. I STARTED UP THE HILL AND WAS APPROACHING THE OTHER ROAD I NEEDED TO TURN ON AND GENTLY APPLIED THE BRAKES. AS SOON AS I APPLIED THE BRAKES, THE VEHICLE WENT OUT OF CONTROL. I TRIED TO PUMP THE BRAKES AND GET THE VEHICLE BACK INTO CONTROL BUT HAD NO LUCK. I THEN CROSSED THE CENTER LINE AND CRASHED HEAD ON INTO THE GUARD RAIL ON THE OTHER SIDE OF THE ROAD. AFTER I HIT THE GUARD RAIL I BOUNCED OFF OF THAT AND HIT AN ON COMING VEHICLE IN THE PASSENGER SIDE WITH THE FRONT END OF MY CAR. I THEN PROCEEDED TO CONTINUE BACK TO THE OTHER SIDE OF THE ROAD AND JUMP A 4FT DITCH AND FINALLY CAME TO A STOP ON THE OTHER SIDE OF THE DITCH. THE FUNNY THING IS THAT THIS ALL HAPPENED WHILE I WAS TRAVELING UP HILL!!! I TRULY BELIEVE THE SO CALLED FOUR WHEEL ANTI-LOCK BRAKES FAILED. THE AIR BAGS NEVER DEPLOYED EITHER! AFTER THE CRASH THE RIGHT FRONT TIRE HAD A HUGE HOLE IN THE SIDE WALL AND I AM NOT TOO SURE THAT THIS WASN'T PART OF THE PROBLEM. THE TORN PART OF THE TIRE IS STICKING OUT AND SEEMS LIKE IT FAILED TOO. I JUST WISH I COULD GET SOMEONE TO INVESTIGATE THIS (GOODYEAR TIRES). *NM

I PURCHASED A 2005 CHEVY TRAILBLAZER LESS THAN A YEAR AGO. SINCE THAT TIME THE VEHICLE HAS BEEN IN THE SERVICE CENTER FOUR DIFFERENT TIMES. EACH TIME THE VEHICLE HAS FAILED TO START. THE DEALER STATES THAT THE REAR HATCH MODULE CONTINUES TO SHORT OUT. THIS MODULE CAUSES THE ENTIRE VEHICLE TO SHORT OUT. I HAVE EXPRESSED MY CONCERNS WITH THE SAFETY OF THIS VEHICLE WITH THE DEALER AND HAVE NOT GOTTEN ANYWHERE. I AN A SINGLE MOTHER OF A TWO YEAR OLD. I AM ONLY INTERESTED IN THE SAFETY OF MY CHILD. JACK SCHMITT CHEVROLET OF O'FALLON ILLINOIS WILL NOT STAND BEHIND THE VEHICLE THAT THEY SOLD OR ADMIT THAT THERE IS A PROBLEM. THE LAST TIME I BROUGHT MY VEHICLE IN FOR THIS PROBLEM THEY TOLD ME THAT IT WAS THE IGNITION. WHEN I CAME TO PICK UP THE VEHICLE AFTER THEY HAD "FIXED" IT, THE VEHICLE WOULD NOT START. THEY ADMITTED THAT IT WAS IN FACT THE REAR HATCH MODULE AGAIN AND THAT THEY HAD MADE AN EDUCATED GUESS THE FIRST TIME IN ORDER TO SAVE TIME. I WOULD LIKE SOMEONE TO HOLD THIS DEALERSHIP RESPONSIBLE FOR THE DEFECT IN THIS CAR AND TO STOP GIVING CONSUMERS THE RUN AROUND. *JB
