COMING HOME FROM WORK, DASH LIGHTS GOT BRIGHTER, AIRBAG LIGHT STAYED ON, CAR TRIED TO STALL AROUND A CORNER WHEN BRAKES WERE PRESSED. TOOK IN FOR SERVICE, HAD ALTERNATOR AND BATTERY REPLACED, ALSO SERPENTINE BELT. THIS WAS 4 MONTHS AGO. PROBLEM WAS NOT FIXED, JUST MADE IT LESS SEVERE. SINCE THAT TIME, WHEN YOU HIT THE BRAKES THE HEADLIGHTS DIM. THE DASH CLOCK COMES ON AND OFF RANDOMLY, THE AIRBAG LIGHT IS ON ALL THE TIME. WHEN IT IS COLD (THE CAR, NOT THE WEATHER), THE TRANSMISSION HAS A HARD TIME SHIFTING. AS OF THIS MORNING IT WILL NOT START. AM GOING TO HAVE IT LOOKED AT TOMORROW MORNING, BUT DO NOT HAVE HIGH HOPES. BOUGHT CAR IN 2006 WITH 8,000 MILES ON IT, HAVE HAD SHIFT LOCK ASSEMBLY REPLACED, WHEEL BEARINGS, BATTERY, ALTERNATOR, SERPENTINE BELT. PROBABLY OTHER THINGS I CANNOT THINK OF RIGHT NOW. THE ELECTRICAL PROBLEM WORRIES ME THOUGH. *TR

2005 AVEO (BOUGHT NEW) WITH TIMING BELT FAILURE DESTROYING ENGINE. HAD THIS HAPPENED ON THE INTERSTATE AT 70 MILES AN HOUR IT COULD HAVE BEEN FATAL. FROM MY RESEARCH GMC HAS KNOWN ABOUT THIS ISSUE SINCE AT LEAST 2006 AND YET HAVE NOT ASSISTED CONSUMERS TO CORRECT THIS NOR RECALLED THEIR CAR. I HAVE READ REPORTS ON ALMOST ALL YEARS OF AVEO HAVING THIS PROBLEM WELL BEFORE THE 60000 RECOMMENDED TIMING BELT REPLACEMENT. TWO DIFFERENT MECHANICS CONFIRMED TIMING BELT FAILURE. ALL I GET FROM GMC IS THE RUN AROUND. UPSET OVER MONEY BUT MORE CONCERNED ABOUT THESE CARS BEING ON THE HIGHWAYS AND CREATING SOME HORRIBLE ACCIDENT WHEN THE ENGINE SUDDENLY STOPS WORKING AND CONTROLLING THE CAR IS DIFFICULT OR IMPOSSIBLE. PLANNING TO GET RID OF MINE, CAN'T AFFORD THE THOUSANDS OF DOLLARS TO FIX NOR DO I TRUST THIS CAR. *TR

WAS ENROUTE TO WORK IN 2005 CHEVROLET AVEO WHEN THE TIMING GEAR PULLEY BROKE ON THE MOTOR. THE ENGINE WAS DESTROYED AS I FOUND OUT LATER. 5 OR 6 WEEKS EARLIER I HAD JUST HAD THE TIMING BELT REPLACED. I HAD IT REPLACED BEFORE FACTORY RECCOMENDATIONS. MY MECHANIC TOLD ME THEN I NEEDED TO HAVE IT CHANGED. THE BELT DID NOT BREAK TO CAUSE ENGINE FAILURE. A CHEAP PLASTIC PULLEY BROKE INSTEAD. WHEN THE PULLEY BROKE THE TIMING BELT WENT LIMP AND THE ENGINE DECIDED TO DEPOSIT SOME VALVES THROUGH 1 PISTON. THIS TO ME IS A SAFETY CONCERN SINCE IT WAS ALL I COULD DO TO GET THE CAR OFF THE INTERSTATE. CHEVROLET KNOWS ABOUT THESE PROBLEMS AND THEY DONT SEEM TO CARE. I DONT THINK THIS VEHICLE SHOULD BE ALLOWED TO BE SOLD. *TR

THE PREVIOUS EVENING WE WERE COMING HOME FROM VISITING SOME FRIENDS ,THE CAR WAS NEVER OVER 100 MILES DAY WE BOUGHT IT UNTIL THE TIME OF THE ENGINE'S DEMISE,WE NOTICED A SLIGHT CLICKING NOISE OVER THE MUSIC OF THE RADIO, PULLING INTO A LIGHTED AREA, WE FOUND ALL FLUIDS FINE, NO DRIPPING, NO HEATING UP, NO STALLING, NO REAL INDICATIONS OF ANY TROUBLE EXCEPT A SLIGHT CLICKING.. THE NEXT MORNING I NOTICED A CLICKING AT START UP, IMMEDIATELY I DROVE OFF TO THE REPAIR SHOP THAT WAS JUST BLOCKS AWAY,WHEN I WAS WITHIN 1 BLOCK OF THE SHOP THE ENTIRE SYSTEM SHUT DOWN, WE WERE FORCED TO GET A WRECKER TO TOW US THE LAST BLOCK. THE INDEPENDENT REPAIRMAN INFORMED US THIS WAS A COMMON PROBLEM WITH THIS MAKE OF AUTO (AVEO) DUE TO A DESIGN DEFECT WITH THE TIMING BELT ,IT WOULD DESTROY THE ENGINE AND HE COULD NOT FIND A REPLACEMENT ENGINE. BECAUSE WE HAD 75 THOUSAND MILES ON THE CAR, (AND IT IS PAID OFF) HE THOUGHT HE HAD HEARD OF A RECALL IN 2006,HE SUGGESTED WE CONTACTED THE AUTO DEALER, AUTO WAY CHEVROLET, HWY 19, CLEARWATER, FLA. WHICH WE DID. WE WERE INFORMED BY THEIR SERVICE DIRECTOR THAT THEY COULD NOT FIND AN OPEN 2006 RECALL, THOUGH A REMINDER TO REPLACE BELT AT 68 K, NO ALERT NOR ADVISORY WAS EVER RECEIVED THOUGH WE DO GET ALL ADVERTISEMENTS AND SHE ADVISED AWC DID NOT HANDLE SUCH A PROBLEM, BUT, THEY WOULD GIVE US GM'S NUMBER, UPON CALLING THAT NUMBER I TALKED WITH A VERY AMIABLE YOUNG MAN IN BUENOS AIRES, WHO ALSO INFORMED ME THEY DID NOT APPEAR TO HAVE A RECALL ON THIS PARTICULAR MODEL, HE THEN CALLED AUTO WAY CHEVROLET, CLW. FLA, USA AND MONITORED THE SERVICE DEPARTMENT NOW TELLING ME IF I WOULD BRING IT TO THEM, THEY COULD EVALUATE THE CAUSE AND MAYBE WORK SOMETHING OUT WITH US.. UPON INTERNET INVESTIGATION WE HAVE FOUND A NUMBER OF INDIVIDUALS COMPLAINING ABOUT THIS YEAR,OF AVEO, HAVING THE ENGINE FAIL IN ROUGHLY THE SAME MILEAGE 68-78 THOUSAND MILES. .
