IGNITION SWITCH IS OVERHEATING. THE LONGER THE CAR IS DRIVEN (10-15 MILES) THE HOTTER IT IS BECOMING. IT HEATS UP SO MUCH THAT THE IGNITION KEY BECOMES QUITE HOT AS WELL...BUT THE SWITCH ITSELF IS EVEN HOTTER. I FEAR THERE WILL BE AN ELECTRICAL FIRE STARTING SOON, AND HAVE ALREADY DECIDED TO STOP AT INTERVALS TO TURN THE IGNITION OFF SO IT COOLS DOWN. IT DOESN'T MAKE ANY DIFFERENCE IF IT'S DRIVEN FAST OR SLOW, DRIVING STILL HEATS UP THE IGNITION SWITCH. THE ONLY ODD OCCURRENCE THAT MIGHT BE SOMEHOW CONNECTED IS THE RIGHT TURN SIGNAL BULB NEEDED REPLACED SINCE THIS STARTED.

WHILE BACKING UP MY VEHICLE I SHIFTED THE TRANSMISSION FROM DRIVE TO REVERSE. THE ENGINE IMMEDIATELY ACCELERATED TO APPROXIMATELY 500 RPM.

ONETIME WHILE THE VEHICLE WAS IN DRIVE AND I HAD TO PRESS HARD ON THE BREAK AND SHUT OFF IGNITION TO AVOID AN ACCIDENT. I SEEMS LIKE IT MOSTLY HAPPENS WHEN IT IS COLD OUTSIDE ( IN THE 30"S F) .

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.
