I AM ON A FIXED INCOME. I BOUGHT THIS CAR USED WITH 22,000 MILES ON IT WHICH I INTENDED TO TAKE CARE OF AND DRIVE FOR YEARS TO COME, IN FACT INTO THE GROUND. THE MANUAL I RECEIVED WITH THE CAR INDICATED THAT THE TIMING BELT SHOULD BE REPLACED AT 100,000. I LIVE IN A RURAL AREA WHERE YOU REALLY NEED A VEHICLE. I HAD DRIVEN TO ANOTHER TOWN FOR A MEDICAL APPOINTMENT. WHILE TRAVELING AT 55 MPH THE CAR JUST DIED IN HEAVY TRAFFIC IN A 55 MPH ZONE. I WAS LUCKY THAT A GOOD SAMARITAN HELPED ME OUT OF THE DANGEROUS CONDITION I WAS IN ON THE ROAD. MY VEHICLE HAD 65,321 MIIES ON IT. I HAD TO HAVE THE CAR TOWED TO A DEALER. IT WAS DETERMINED THE TIMING BELT BROKE CAUSING VALVE DAMAGE. I WAS TOLD IT WOULD COST $5,000 TO REPAIR IT WHICH IS WHAT I PAID FOR THE VEHICLE. I DID NOT HAVING $5,000 SO I JUNKED THE CAR. THIS ORDEAL CAUSED SIGNIFICANT PROBLEMS FOR ME FINANCIALLY, EMOTIONALLY AND PHYSICALLY. I WAS 62 AT THE TIME. THE WEBSITE CARCOMPLAINTS HAS 56 SIMILAR COMPLAINTS RELATED TO 2004 CHEVY AVEOS. ALL OF THE TIMING BELTS FAILED BELOW 100,000 MILES. THERE ARE SIMILAR COMPLAINTS FOR THE 2005 CHEVY AVEO. WHY WASN'T I NOTIFIED ABOUT THIS PROBLEM SO I WOULD NOT LOSE MY SHORTS ON MY VEHICLE. I COULD HAVE BEEN KILLED. THE EVENT WAS TERRIBLY FRIGHTENING. I SUFFER FROM HEART FAILURE. MY NEW CAR PAYMENT IS VERY HARD TO DEAL WITH ON A FIXED INCOME. I TOOK EXCELLENT CARE OF THE CAR. I SHOULD HAVE BEEN CONTACTED ABOUT SUCH DANGEROUS CONDITION. I WOULD LIKE SOME ANSWERS.

THIS IS THE SAME VEHICLE AS NHTSA INCIDENT 10393028 (SNAPPED PLASTIC THERMOSTAT HOUSING UNIT). DRIVING ON A MULTIPLE LANE FREEWAY AT ~65MPH AND THE TIMING BELT SNAPPED (HIGH PITCHED WHISTLE LIKE THE CAR WINDOW WAS SLIGHTLY OPEN). IMMEDIATELY LOST ALL SPEED CONTROL AND BEGAN RAPIDLY DECELERATING. THANKFULLY, WAS IN RIGHT HAND LANE AND WAS ABLE TO COAST OFF THE NEXT AVAILABLE EXIT. LIKELY WOULD HAVE BEEN KILLED HAD I BEEN IN ANY OTHER LANE IN MORNING TRAFFIC AND LOST CONTROL OF VEHICLE. ONCE STOPPED, CAR COULD NOT BE TURNED BACK ON AND WOULD NOT MOVE UNTIL TURNED INTO ACC MODE WHERE IT FINALLY ALLOWED ME TO SHIFT INTO NEUTRAL. HAD TO BE TOWED, EVENTUALLY TO THE DEALERSHIP. ENGINE DAMAGE WAS CATASTROPHIC AND REQUIRED EXTENSIVE AND EXPENSIVE REPAIRS (3 WEEKS AND APPROXIMATELY $2,700). SNAPPED TIMING BELT ALSO BENT PISTONS AND VALVES AND REQUIRED THE WATER PUMP TO BE REPLACED. THIS IS CLEARLY A KNOWN ISSUE THAT SHOULD BE DEALT WITH BY CHEVROLET, RATHER THAN HIDING BEHIND THE 60,000 MILE REPLACEMENT, WHICH IS LAUGHABLY LOW FOR A TIMING BELT. FURTHER - MY TIMING BELT WAS SUPPOSED TO HAVE BEEN REPLACED AT 50,000 MILES AND THUS NOT ONLY DID A CHEVROLET DEALERSHIP LIE TO ME, THEY PUT MY LIFE AT RISK BY KNOWING THIS WAS AN ISSUE THAT WOULD INEVITABLY OCCUR LONG BEFORE THE NEXT SCHEDULED BELT REPLACEMENT. THIS CAR HAS BEEN METICULOUSLY MAINTAINED WITH OIL CHANGES EVERY 3,000 MILES AND ONLY 5,000-10,000 MILES DRIVEN/YEAR. THERE WAS NO REASON FOR THE TIMING BELT TO SNAP OTHER THAN BEING A FAULTY PART THAT SHOULD HAVE BEEN RECALLED. *TR

I WAS DRIVING APPROXIMATELY 25MPH WHEN SUDDENLY I HEARD A STRANGE, LOUD RUBBING/ CLATTERING NOISE COMING FROM UNDER THE HOOD. I PULLED THE VEHICLE OVER AND TURNED THE ENGINE OFF. MY BOYFRIEND, WHO IS A MECHANIC, LOOKED AT THE ENGINE AND SAID THE TIMING BELT WAS BROKEN. THE VEHICLE WOULD NOT RESTART AND HAD TO BE TOWED. NOW I AM FINDING OUT THAT THIS IS A KNOWN PROBLEM IN THIS PARTICULAR 4 CYLINDER GM VEHICLE. THIS ENGINE IS AN INTERFERENCE ENGINE. THIS MEANS THAT THE ONLY THING PREVENTING THE VALVES FROM STRIKING THE PISTONS DURING VEHICLE OPERATION IS THE TIMING BELT. IF/ WHEN IT BREAKS, IT CAUSES CATASTROPHIC ENGINE DAMAGE, OFTEN REQUIRING ENGINE REPLACEMENT. ONE OR MORE OF THE TIMING BELT PULLEYS ARE MADE OF PLASTIC. WHEN THE TIMING BELT PULLEY BREAKS, SHARDS OF PLASTIC SNAP OFF AND BECOME LODGED INSIDE OF THE ENGINE, RENDERING THE ENGINE USELESS. ALSO, AT HIGH RATE OF SPEED, THE VALVES BECOME BENT WHEN THE BELT/ PULLEY(S) MALFUNCTIONS. THIS IS BOTH COSTLY AND DANGEROUS TO THE CONSUMER, AND THE MANUFACTURER SHOULD HAVE MADE ALL PULLEYS AND MOVING PARTS ON THE ENGINE OUT OF METAL INSTEAD OF PLASTIC. *TR

CAR STALLED ON A BUSY 4 LANE INTERSTATE WITH MY SON INLAW DAUGHTER AND GRANDDAUGHTER IN VEHICLE WITHOUT WARNING. THE CAR BARELY COASTED ENOUGH TO MAKE IT OFF THE HIGHWAY INTO EMERGENCY LANE. CAR FAIL TO START AGAIN. HAD CAR TOWED TO CHEVY DEALERSHIP. SERVICE DEPARTMENT CALLED AND SAID THE TIMING BELT HAD BROKEN. THE CAR ONLY HAD 59,000 MILES ON IT. I STATED TO THE SERVICE MANAGER THAT THE BELT SHOULD STILL BE UNDER WARRANTY AND WAS DISAPPOINTED THAT ABOUT IT. HE AGREED ALSO THAT THE BELT SHOULDN'T HAVE FAILED WITHIN THAT AMOUNT OF MILEAGE. HE GAVE ME THE NUMBER TO CALL CHEVY TO SEE WHAT COULD BE DONE TO SOLVE THE PROBLEM. THEY REFUSED TO FIX THE PROBLEM. SO NOW I'M STUCK WITH A PILE OF JUNK BECAUSE THEY USED A CHEAP MADE BELT THAT HAS PREMATURELY FAILED ON COUNTLESS 04 & 05 AVEOS ENOUGH TO HAVE A WEBSITE CALLED AVEOSFAIL.COM. I READ STORIES THAT STATED THESE CHEAP BELTS FAILED ANYWHERE FROM 18,000 UP. MOSTLY WHERE IN THE 59,000 TO 65,000 MILE RANGE. US TAX PAYERS HAD TO BAIL THE COMPANY OUT WHY CAN'T THEY TAKE CARE OF THIS PROBLEM? THAT MIGHT BE ONE OF THE REASONS THEY HAD TO BE BAILED OUT IN THE FIRST PLACE, BECAUSE I WOULD BUY A STUBBORN MULE BEFORE I EVER BUY ANOTHER CHEVY! THE MULE WOULD BE MORE RELIABLE. THE CAR WAS TOWED BACK TO MY HOUSE. I TOOK APART THE TIMING COVER TO FIND THE BELT WASN'T BROKEN BUT THE RIBS ON THE BELT WERE BASICALLY FALLING OFF THE BELT, LIKE THEY HAD COME UNGLUED. WHY SHOULD WE ALL SUFFER BECAUSE OF THEIR POOR BELT DESIGN OR MANUFACTURER FLAWS. IF THEY DON'T STEP UP AND TAKE RESPONSIBLITY THEY SHOULD BE ASHAMED AND SHOULDN'T BE BAILED OUT BY THE TAX PAYERS PERIOD. *TR
