I WAS PASSING THROUGH AN INTERSECTION IN A 2005 CHEVY AVEO, I WAS HIT HEAD ON BY A FORD RANGER PICKUP TRUCK, BOTH VEHICLES WERE TOTALED. THE OTHER DRIVERS AIRBAG HAD GONE OFF BUT MINE DID NOT. AS A RESULT HE WAS FINE, BUT I WAS KNOCKED TEMPORARILY UNCONSCIOUS. I SPENT THE REST OF THAT DAY IN A HOSPITAL GETTING X-RAYS DONE AND WAS LAID UP IN BED FOR THE NEXT WEEK ON PAIN KILLERS AND MUSCLE RELAXERS. THE PAIN (PRIMARILY IN MY NECK, UPPER BACK, AND MY HEAD WHICH HIT THE STEERING WHEEL) HAS STILL YET TO GO AWAY NOW ALMOST 3 WEEKS LATER. *TR

I HAVE A 2005 CHEVROLET AVEO WITH 50,000 MILES. I HAVE DONE THE ROUTINE MAINTENANCE ON THE VEHICLE. HOWEVER, A WEEK AGO THE TIMING BELT BROKE AND RUINED MY ENGINE. IN MY MAINTENANCE BOOK IT SAYS NOT TO CHANGE THE BELT UNTIL 60,000 MILES AND GM IS TELLING ME IT IS MY PROBLEM SINCE I AM NO LONGER UNDER WARRANTY. I HAVE LOOKED ON LINE AND FOUND OTHERS WHO HAVE PROBLEMS WITH THEIR TIMING BELTS GOING BEFORE THE REQUIRED MAINTENANCE. CAN YOU PLEASE HELP. THEY WANT $2,200 TO FIX VEHICLE. THIS OCCURRED WHILE I WAS DRIVING AND I LOST POWER IN MY CAR WHILE GLIDING THROUGH A RED LIGHT. THANK GOD NO ONE HIT ME. UPDATED IVOQ 02/02/11 *TR

WHILE DRIVING I NOTICED A SMOKE COMING FROM UNDER THE HOOD. I LOOKED DOWN TO SEE MY ENGINE TEMP INDICATOR ON HOT. I WASN'T FAR FROM MY HOME LUCKILY AT THE TIME, SO I DROVE IT HOME. I OPENED MY HOOD A COUPLE MINUTES LATER TO FIND WATER SIZZLING ON MY THERMOSTAT HOUSING. (WHICH IS CONSTRUCTED OF TWO PIECES OF PLASTIC, GLUED TOGETHER) I TRIED TO LOOK UP INFO ON IT AND CAME ACROSS ALL KINDS OF PEOPLE COMPLAINING ABOUT THIS EXACT SAME PROBLEM WITH THEIR 2004-2005 CHEVY AVEO LS. THE EARLIEST COMPLAINT I SAW WAS AS EARLY AS JANUARY OF 2009. AFTER LOOKING AT YOUR WEBSITE, I FOUND OUT THAT THERE IS NO RECALLS ON THIS ITEM AT ALL. ALSO, THE ONLY PLACE TO GET A NEW ONE IS AT THE DEALERSHIP FOR $91.00 AND THAT IS WITHOUT LABOR COST. IN ADDITION, IT IS NOT COVERED UNDER WARRANTY. *TR

WAS DRIVING TO WORK AND WENT THROUGH A DRIVE THROUGH FOR COFFEE. NOTICED THAT WHILE IDLE, MY CAR STARTED TO OVER HEAT. CONTINUED ON TO WORK APPROX 1 MILE DOWN THE ROAD. WHEN I GOT THERE I OPENED THE HOOD AND FOUND THAT A HOSE WAS NO LONGER CONNECTED TO THE THERMOSTAT HOUSING. THEN I NOTICED THAT THE PLASTIC HOUSING ITSELF WAS CRACKED IN HALF AND HANGING OFF THE CAR. IT COST ME ABOUT $80 FOR A REPLACEMENT METAL PART WHICH I HAD INSTALLED BY A FRIEND. THIS HAPPENED DURING THE SUMMER 2010; CAR HAD APPROX 51,000 MILES. IT IS NOW DECEMBER 2010, AND CAR HAS APPROX 56,00 MILES. MY CHECK ENGINE LIGHT IS ON AND I BROUGHT THE CAR TO A CAR PART STORE TO HAVE THEM CHECK THE CODE. APPARENTLY NOW I HAVE TO REPLACE THE OXYGEN SENSOR, WHICH COSTS ABOUT $150.00 + LABOR. I BOUGHT THIS CAR USED IN 2007 AND STILL HAVE ABOUT 2 YEARS LEFT TO PAY ON IT. THE WARRANTY IS NO LONGER GOOD. *TR

I CALLED THE DEALERSHIP AND OUR EXTENDED WARRANTY THAT WE PAID SO MUCH FOR EXPIRED IN MAY OF 2010. I TOLD THEM THAT IT IS REALLY A DEFECT IN THE CAR BUT THEY WANT TO CHARGE ME $115 PER HOUR TO FIX IT. I SEE THAT THIS HAPPENS TO ALOT OF THE AVEO CARS. I THINK GM SHOULD PAY FOR THE FIX. *TR
