MY 2004 CHEVY AVEO BROKE DOWN IN THE MIDDLE OF AN INTERSECTION AT 47,652 MILES. THE CAR WOULDN'T START AND COULDN'T BE MOVED WHILE MY DAUGHTER AND GRANDSON WERE STRANDED IN TRAFFIC. THE PROBLEM TURNED OUT TO BE THE TIMING BELT WHICH SHOULD HAVE LASTED 2X THE MILEAGE. THEN ENGINE RATTLED AFTER THAT REPAIR. ON 17AUG08 MY CAR STARTED SMOKING FROM UNDER THE HOOD. WHEN I OPENED THE HOOD, ANTIFREEZE COVERED EVERYTHING. I TOOK IT TO THE DEALER WHO TOLD ME THE BELT TENSIONER WAS BAD CAUSING THE RATTLE AND THE THERMOSTAT HOUSING CRACKED CAUSING THE ANTIFREEZE TO SPEW UPWARD AND CASCADE OVER THE TOP OF THE ENTIRE ENGINE. *TR

THERE ARE NO EVENTS LEADING UP TO THIS PROBLEM. THE LOCK ON THE DRIVER'S SIDE DOOR HAS FALLEN INTO THE DOOR. THIS MAKES THE DOOR IMPOSSIBLE TO LOCK OR UNLOCK FROM THE OUTSIDE. WHEN THE WINDOW IS ROLLED DOWN THE LOCK ALSO LOCKS. THE PROBLEM HAS NOT YET BEEN SOLVED. *TR

AIR BAG INDICATOR LIGHT CAME ON IN MID JANUARY 2008 AND HAS REMAINED ON. THE CAR JUST WENT OUT OF WARRANTY IN AUG 2007. SINCE I HAVE BEEN DEPLOYED FOR 15 MONTHS, I WAS NOT ABLE TO DISCOVER THIS PROBLEM WHILE IT WAS STILL UNDER STANDARD WARRANTY. AFTER CONTACTING CHEVROLET ABOUT SEVERAL ISSUES WITH THE BRAKES AND AIR BAG LIGHT, THEY INSTRUCTED ME TO GET IT DIAGNOSED. THE DIAGNOSIS REVEALED AN ECW FAILURE BUT NOTHING COULD BE FOUND WRONG WITH THE BRAKES. RECOMMENDATION FROM CHEVROLET SERVCO IS TO HAVE ECW FIXED. AFTER THE OCCURRENCE WITH THE BRAKES, MY HUSBAND BEGAN DRIVING THE VEHICLE. *TR

REAR BRAKES LOCKED ON APPLICATION, LUCKILY RIGHT IN MY DRIVEWAY. RELEASED BY ROCKING BACK AND FORTH, ONLY TO LOCK AGAIN....PULLED DRUMS MYSELF TO FIND ALL FOUR LININGS DELAMINATED FROM SHOES! PHONED GM CANADA AND GOT ABSOLUTELY NOWHERE UNTIL I MENTIONED THE FACT THAT I CAREFULLY TOOK PICTURES AND IT WAS LUCKY THAT NO ONE WAS KILLED! HAVING A SUDDEN CHANGE OF HEART, THEY PHONED MY DEALERSHIP AND ARRANGED FOR A FREE SET OF SHOES, WHICH I INSTALLED, SINCE I LIVE THREE HOURS FROM A DEALERSHIP. I'M SATISFIED WITH THE PROCESS, EXCEPT FOR THE FACT THAT THIS COULD CONCEIVABLY HAPPEN TO ANY AVEO AT ANY TIME! MINE HAD 70000 KMS. (45,000 MILES) ON IT AT THE TIME, 85% LININGS! HAVE YOURS CHECKED!!

FIRST THING THAT WENT WRONG WITH THE CAR IS THE CLOCK FOR NO REASON AT ALL IT CHANGES TO 12:00 IT DOES IT WHEN THE CAR IS ON AND RUNNING IT ALSO DOES IT WHEN YOU FIRST TURN THE CAR ON. THIS HAS BEEN REPLACED ONCE AND HAS FAILED A SECOND TIME AGAIN. SECOND IS MY GEAR SHIFTER I HAVE AN AUTOMATIC AND IT STICKS IN PARK ALL THE TIME AND ALL YEAR LONG THE FIRST TIME IT HAPPENED I WAS SITTING AT A GAS PUMP AND I WAS COMPLETELY STUCK AND IT WOULDN'T MOVE SO I HAD THE CAR TOWED TO MY DEALER AND THEY FIXED IT BUT IT STUCK 10 + MORE TIMES SINCE 5 TIMES I TOOK IT TO THE DEALER AND 3 TIMES IT WAS REPAIRED. I BOUGHT MY CAR IN 2004 AND TOO THIS DAY IT STILL STICKS I ACTUALLY HAVE PARTS BEING ORDERED AGAIN TO GET IT FIXED. THIRD IS MY KEY AND ALARM I CAN'T USE MY SECURITY ALARM ON MY CAR BECAUSE WHEN ITS SET ON IT GOES OFF ABOUT EVERY HALF HOUR FOR NO REASON. FOURTH IS MY HEAD LIGHTS AND BRAKE LIGHTS. I WAS TRAVELING IN A BIG CITY BUFFALO WHEN ALL THREE OF MY BRAKE LIGHTS STOPPED WORKING I WENT TO AN AUTO SHOP TO GET THEM REPLACED AND THEY REPLACED THEM RIGHT THERE AND THE NEW ONES WOULDN'T EVEN WORK. MY HEADLIGHTS GO OFF WHEN EVER AND TURN BACK ON AFTER AWHILE. EVEN WHEN I'M DRIVING DOWN THE STREET BUT THE DEALER CLAIMS THEY CAN'T FIND ANYTHING WRONG WITH THAT PART. FIFTH IS MY BALL JOINT WAS DEFECTED AND I WENT THREW 4 PAIRS OF TIRES WITHIN 2 YEARS BEFORE MY DEALER REALIZED WHAT THAT PROBLEM WAS. SIXTH BOTH THE REAR STRUT HOLDING MOUNTS JUST FELL OFF CAR AND MY STRUTS WENT THREW MY BACK BOTTOM TRUNK. THE DEALER SAID HE NEVER SEEM ANYTHING LIKE IT. THE RIGHT SIDE WENT FIRST AND THAT WAS FIXED THEN ABOUT A WEEK LATER THE LEFT SIDE WENT I REPLACED EVERYTHING BRAND NEW AND IT HAPPENED AGAIN A THIRD TIME THE LEFT STRUT AND HOLDING MOUNT FAILED. I ACTUALLY HAVE PARTS ORDERED FOR THAT AS WELL RIGHT NOW. A SMALLER COMPLAINT IS THE CIG. LIGHTER OUTLET DOESN'T WORK, AND THAT'S BEING REPLACED FOR THE SECOND TIME. *TR
