I APPLIED THE BRAKE AND AS SUSPECT THE ENGINE WHINED DUE TO BOTH BRAKE AND ACCELERATOR BEING PUSHED AT THE SAME TIME. I PLACE IT IN NEUTRAL AND CAME TO A STOP. I APPLIED THE PARKING BRAKE AND TRIED TO DISLODGE THE ACCELERATION PEDAL. IT DIDN'T SEEM TO MOVE BUT WHEN I PUT THE CAR BACK INTO DRIVE THE PROBLEM HAD BEEN REMEDIED. I'M SO HAPPY THAT MY SON WAS NOT IN THE CAR AND THAT I WAS ON THE HIGHWAY AND NOT IN THE CITY! *TR

THE CAR WAS TOWED TO A CERTIFIED MECHANIC. THE MECHANIC FOUND THAT THE TIMING BELT HAD BROKEN PREMATURELY. IT WAS NOT DUE TO BE CHANGED UNTIL 60,000 MILES. (ORIGINALLY 90,000 IN THE MECHANICS BOOK, AMENDED BY GM) THE TIMING BELT FAILURE CAUSED THE VALVES IN THE ENGINE TO BE BENT AND THE ENGINE RENDERED USELESS.

I HAVE A 2004 CHEVY AVEO THAT ONLY HAS 65K MILES ON IT AND GETS REGULAR OIL CHANGES. I WENT IN AND HAD MY TRANSMISSION FLUID FLUSHED AND WAS TOLD THE CAR LOOKED GREAT. DROVE A FEW OTHER PLACES, AND WAS ON A STEEP HILL, TURNING AROUND (AS I HAVE DONE MANY TIMES BEFORE), AND ALL OF A SUDDEN SMOKE WAS POURING OUT OF MY ENGINE. I PARKED IMMEDIATELY. MY THERMOSTAT HOUSING PIECE (PLASTIC) HAD CRACKED IN HALF AND WAS SPEWING ANTIFREEZE. IN THE TWO SECONDS THE CAR WAS ON, I LOST HALF MY ANTI-FREEZE AND MY ENGINE COMPARTMENT IS COVERED IN ANTI-FREEZE. FURTHER, THE PART IS HARD TO FIND AND WILL TAKE SEVERAL DAYS FOR A REPLACEMENT. THIS PART BROKE OUT OF THE BLUE, IN THE MIDDLE OF ROUTINE DRIVING. THERE'S NO WAY TO DRIVE IT UNTIL IT'S FIXED - THE CAR WILL HAVE TO BE TOWED. I HEAR THAT THE PART IS NOW BEING MADE IN ALUMINUM AND THAT THIS IS A COMMON PROBLEM WITH THIS CAR (EVERY 50-70K THIS PIECE JUST INEXPLICABLY CRACKS). I FIRMLY BELIEVE THAT THIS SHOULD BE PART OF A STANDARD RECALL. HAD THIS PIECE BROKE AT ANY OTHER TIME (SUCH AS FIVE MINUTES PRIOR, WHEN I WAS ON THE FREEWAY) THERE WOULD HAVE BEEN DIRE CONSEQUENCES. FURTHER, HAD I ATTEMPTED TO DRIVE THE CAR ANY FURTHER, I COULD HAVE HAD AN ENGINE FIRE OR SEVERAL OTHER PROBLEMS. THIS HAS RESULTED IN THREE DAYS OF TIME AND ENERGY TO GET THIS REPAIRED (HOPEFULLY TO BE COMPLETED TOMORROW). THIS PLASTIC PIECE IS NOTHING BUT A SAFETY HAZARD AND I CONSIDER MYSELF LUCKY TO HAVE ESCAPED IN ONE PIECE. I'M YET TO FIND OUT WHAT KIND OF DAMAGE THE ANTI-FREEZE WILL DO TO MY CAR IN THE TIME IT TAKES TO GET THE CAR INTO THE SHOP TO BE FIXED UP. *TR

ENGINE STOPPED RUNNING. AT FIRST I WAS TOLD IT WAS THE TIMING BELT BUT THAT WAS NOT SUPPOSED TO BE CHANGED TILL AROUND 60,000 MILES. THE CAR HAS ONLY 48,000 MILES ON IT. I WENT AND BOUGHT A TIMING BELT AND A WATER PUMP BECAUSE I WAS TOLD THAT IF I CHANGED THE BELT I MAY AS WELL CHANGE THE WATER PUMP ALSO. AFTER A GOOD DEAL OF MONEY I WAS TOLD IT WAS AN ENGINE FAILURE BECAUSE OF A "VALVE RING" HAD WORN AWAY. I NEED TO PUT A "NEW" ENGINE IN IT AT CONSIDERABLE COST. I HAVE BEEN LAID OFF FOR OVER A YEAR AND THIS HAS CREATED A HARDSHIP FOR ME. I CAN NOT AFFORD ANOTHER CAR PAYMENT AND THE COST TO FIX THIS CAR, ALTHOUGH CHEAPER THAN BUYING ANOTHER, IS STILL A LOT OF MONEY FOR ME. NOT ONLY IS IT HARD ENOUGH TO FIND WORK IT IS NEARLY IMPOSSIBLE WITHOUT A CAR. I BELIEVE THIS FAILURE SHOULD NOT HAVE HAPPENED AT 48,000 MILES! I AM 55 YEARS OLD AND HAVE OWNED CHEVY'S ALL MY LIFE. NOT HAPPY.
