TL*-THE CONTACT OWNS A 2004 CHEVROLET AVEO AND STATED THAT SINCE SHE PURCHASED THE VEHICLE THE PASSENGER'S SIDE SEAT BELTS NEVER LOCKED CORRECTLY IN PLACE. SHE TOOK THE VEHICLE TO THE DEALER, AND THEY REPLACED THE SEAT BELT, BUT SHE BELIEVED THAT THEY SWITCHED IT FROM THE FRONT TO THE BACK. CURRENTLY, THE SEAT BELT HAS BEEN LOCKING WHEN ANYONE SAT IN THE BACK. ALSO, THE DOME LIGHTS IWERE CONSTANTLY BURNING OUT. THIS HAD OCCURRED ABOUT THREE OR FOUR TIMES. IN ADDITION, THE CLOCK DID NOT WORK WHENEVER SHE SET THE TIME, IT WOULD CHANGE ON ITS OWN ACCORD. SIMILARLY, THE KEY LOCK ON THE DRIVER'S SIDE FELL THROUGH THE DOOR PANEL. THE DEALER REPAIRED AND PAINTED THE DOOR THE WRONG COLOR, AND THEY PAINTED OVER THE DOOR HANDLE. JUST LAST WEEK FINALLY, THE TENSION PULLEY FELL OFF WHILE SHE WAS DRIVING ON THE FREEWAY. THEY TOLD HER THIS WAS NORMAL WEAR AND TEAR ON THE VEHICLE AND REFUSED TO MAKE FURTHER REPAIRS. THE FAILURE MILEAGE WAS 32, AND THE CURRENT MILEAGE WAS 60,750.*AK

SUMMER 2005 THE DRIVER'S SIDE WINDSHIELD WIPER STOPPED WORKING DURING A RAINSTORM WHILE OPERATING VEHICLE LEAVING MY VISIBILITY EXTREMELY IMPAIRED. UPON SUBSEQUENT EXAMINATION, I NOTICED THAT THE NUT HOLDING THE WIPER TO THE POST HAD LOOSENED AND BACKED OFF. THIS STRIPPED THE MATING GROVES OFF BOTH THE WIPER ARM (CAST ALUMINUM) AND POST (SOFT METAL). EVEN AFTER RE-TIGHTENING THE NUT, THE WIPER WAS UNABLE TO MOVE BECAUSE THE WIPER ARM AND POST WERE TOO BADLY DAMAGED; ALL OF THE GROVES WERE ENTIRELY REMOVED FOR THE CAST ALUMINUM WIPER ARM. I WAS UNABLE TO GO TO A DEALER TO HAVE THIS REPAIRED. I DRILLED A KEYWAY INTO BOTH THE WIPER ARM AND POST. I FILLED THE KEYWAY WITH A PORTION OF A LARGE PAPER CLIP. THE DAMAGE REMAINS THIS WAY CURRENTLY. SUMMER 2005 HAVING EXPERIENCED THE PROBLEM WITH THE AVEO 2004 (ABOVE) I TIGHTENED THE NUTS ON BOTH THE PASSENGER AND DRIVER'S WIPERS ON MY AVEO 2005. JANUARY 2007 THE DRIVER'S SIDE WINDSHIELD WIPER STOPPED WORKING DURING A SNOWSTORM WHILE OPERATING VEHICLE LEAVING MY WIFE'S VISIBILITY EXTREMELY IMPAIRED. UPON SUBSEQUENT EXAMINATION, I NOTICED THAT THE NUT HOLDING THE WIPER TO THE POST HAD LOOSENED AND BACKED OFF EVEN WITH RE-TIGHTENING THIS NUT IN THE SUMMER OF 2005. THIS STRIPPED THE MATING GROVES OFF BOTH THE WIPER ARM (CAST ALUMINUM) AND POST (SOFT METAL). I HAVE TAKEN THIS CAR TO THE DEALER TO HAVE BOTH THE WIPER ARM AND POST REPLACED. I AM CURRENTLY WAITING ON PARTS TO HAVE TO REPAIR MADE.--AFTER SEARCHING THE WEB I DISCOVERED THAT SOMEONE ELSE HAD A PROBLEM WITH THEIR DRIVER'S SIDE WIPER ARM NUT COMING LOOSE.

MAJOR FUEL LEAK ON MY 2004 CHEVROLET AVEO. LEFT ME STRANDED. PUMPED OUT 9 GALLONS OF GAS IN 20 MILES. LUCKILY NO FIRE. FOUND THE PLASTIC RETAINER HOLDING THE MAIN FUEL LINE CRACKED AND ALLOWED THE FUEL LINE TO COME LOOSE SPRAYING GAS OVER THE BOTTOM OF THE CAR. THEY WILL PUT ANOTHER PLASTIC RETAINER ON THE LINE BUT HOW LONG WILL THAT LAST? CONSIDER THIS A MAJOR DEFECT AND COULD LEAD TO VEHICLE FIRES WHICH COULD BE DEADLY. I WAS LUCKY BUT SOMEONE ELSE MIGHT NOT BE. I DO NOT LIKE THE FIX. A BETTER FORM OF LINE CLAMPING SHOULD BE USED. I NOTIFIED GM AND THERE IS NO RECALLS AT THIS TIME. THEY TOOK THE INFORMATION AND PUT IT ON FILE. I WOULD LIKE TO BE COMPENSATED FOR TOWING AND THE LOST FUEL. GM WILL NOT DO THIS. NOTE:THE CAR IS AT KNEBEL AUTO IN HIGHLAND ILL NOT THE DEALER BECAUSE IT IS OUT OF WARRANTY. *JB

I PURCHASED MY 04 CHEVY AVEO ON JUNE 20,06. FIVE DAYS LATER THE BRAKES WERE METAL TO METAL. MY CAR WAS NOT SAFETY INSPECTED BEFORE THE SALE. SINCE THEN I HAVE TAKEN THE CAR BACK TO WHERE I PURCHASED IT SEVERAL TIMES AND HAVE EVEN HAD THE SERVICE MANAGER TO RIDE WITH ME TO SHOW HIM THAT THE BRAKES ARE STICKING. (THE CALIPERS NEED TO BE REPLACED) TIM MARBURGER CHRYSLER/DODGE TRIED TO SAY THAT IS WAS A WARPED ROTOR DUE TO EXCESSIVE MOUNTAIN DRIVING, MY CAR WAS ONLY DRIVEN 7 MILES ONE WAY TO GO CAMPING AND 7 MILES BACK ONCE A WEEK. I WOULD HARDLY CALL THIS EXCESSIVE. THE FIRST TANK OF GAS I GOT THE MILEAGE OF 284 MILES SINCE 06/20/06 UNTIL NOW 10/10/06 MY GAS MILEAGE FOR A TANK OF GAS IS NOW 210 MILES. NOBODY AT THE DEALERSHIP HAS OFFERED TO FIX MY CAR. I HAVE BEEN CUSSED, TALKED TO LIKE A DOG. THE GENERAL MANAGER DENNY FRUITH SLAMMED MY CAR DOOR AND PROCEEDED TO ARGUE WITH ME IN THE FRONT PARKING LOT IN FRONT OF THE SHOWROOM DOORS. REFUSED TO FIX MY CAR AND IT WAS STILL UNDER WARRANTY, THE DEALERSHIP PUT MY LUG NUTS ON SO TIGHT THAT THEY COULD NOT BE MANUALLY TAKEN OFF. THE VICE PRESIDENT OF THE COMPANY MR. FELIX MCCLAT REFUSED TO FIX MY BRAKES AND ALSO REFUSED TO EVEN LET ME COME TO THE DEALERSHIP AND HAVE THEM LOOSEN MY LUG NUTS. AND THE CAR WAS STILL UNDER WARRANTY. THE BRAKES ON MY CAR WILL PUT THEMSELVES ON WITHOUT ME PRESSING THE PEDALS. AND WHEN YOU DO PRESS THE PEDALS YOU CAN BE GOING DOWN HILL AND TAKE YOUR FOOT OFF THE PEDAL AND THE BRAKES GRAB AND THE CAR WILL COME TO ALMOST A COMPLETE STOP...DOWN HILL. ALL THIS WAS SHOWN TO THE SERVICE MANAGER DAVID ANDERSON AND THE CAR HAS NOT BEEN FIXED YET. *JB
