I TRADED IN A 2004 P.T.CRUISER TO GET A 2005 CHEVY AVEO AT THE TIME IT HAD 21000 MILES WHEN I GOT IT. MY WARRANTY WAS GOOD TILL 36000. I HAD LOTS OF ISSUES WITH A NOISE THAT STILL TO THIS DAY HAS NOT BEEN CORRECTED EVEN AFTER THREE ATTEMPTS UNDER MY CAR BY THE CHEVY SERVICE DEPT. I THEN HAD A COMPUTER RECALL OR SOMETHING THAT HAD TO BE REPLACED I ALSO HAD A GAS CAP THAT MALFUNCTIONED AND A CLOCK THAT HAD TO BE REPLACED. THOSE ARE THE NON LIFE THREATENING ISSUES. I HAD AN INCIDENT INSIDE OF THE ORIGINAL WARRANTY WHERE THE CAR THREW PARTS OUT OF THE ENGINE. IT WAS THE SERPENTINE BELT AND THE BRACKET THAT WAS METAL THAT IT WAS MOUNTED ON BROKE OUT OF THE ENGINE AS I WAS DRIVING IT. I AM CURRENTLY AT 55000 AND I HAVE THE POWER TRAIN ON IT. IN THE LAST MONTH I HAVE HAD THE CAR IN MY POSSESSION 1 WEEK THE REST IT'S BEEN IN THE SERVICE DEPT. A MONTH AGO THE PLASTIC AND YES THAT'S PLASTIC HOUSING FOR THE THERMOSTAT BLEW APART ON THE INTERSTATE CAUSING US TO HAVE TO DIAL 911 TO GET HELP BECAUSE WE WERE TRAPPED. TWO WEEKS AGO IT SPIT OUT THE TIMING BELT AND THE VALVES GOT BENT AND THE VALVE COVER WAS DAMAGED. WE DON'T KNOW WHAT PARTICLES ENDED UP IN THE ENGINE FOR NOW. I HAVE CONTACTED CHEVROLET ON ALL THESE ISSUES AND I ASKED THEM BEFORE MY WARRANTY WENT OUT AND RIGHT AFTER THE FIRST INCIDENT TO GIVE ME BACK THE MONEY FOR THE CAR. THEY CALLED ME TODAY AND SAID I DIDN'T HAVE A CASE BECAUSE THE WARRANTY WAS OUT I REMINDED THEM I HAD BEEN ASKING SINCE BEFORE AT THE FIRST INCIDENT WITH THE SERPENTINE AND BRACKET AND THEY SAID SORRY THE WARRANTY IS OUT. I REMINDED THEM I HAVE PICTURES OF THOSE PARTS AND CAN PROVE IT BUT THAT STILL WASN'T GOOD ENOUGH! I SPOKE TO HANNAH A DISTRICT SPECIALIST TODAY AND THAT IS WHO LIED TO HERSELF AND SAID THESE OCCURRENCES WERE AFTER THE WARRANTY. I HAVE PROOF CAN YOU PLEASE HELP BEFORE MY FAMILY DIES AND THEN WE HAVE DEPENDENTS WHO WILL OWN THE VERY COMPANY THE GOV'T IS TRYING TO BAIL OUT. I NEED YOU TO INTERVENE BEFORE I GO TO COURT OVER THIS. *TR
