2005 CHEVY AVEO. THERMOSTAT IS ORIGINALLY, FROM FACTORY, PERMANENTLY ENCASED IN A PLASTIC TYPE HOUSING. THIS IS ALL ONE (1) PIECE. CHEVY HAS SUPERSEDED THIS ITEM WITH A METAL TYPE HOUSING WITHIN THEIR RANKS/COMPUTERS, BECAUSE IT WAS A KNOWN ISSUE. THIS ITEM (PLASTIC THERMOSTAT HOUSING) KNOWINGLY SPLITS AS EARLY AS 30,000 MILES. FOR US IT WAS ABOUT 46,000 MILES. THIS WAS NEVER A RECALL ITEM NOR WAS ANY INFORMATION EVER SENT OUT WARNING ABOUT IT. FAILURE OF THIS PART LEADS TO THE KNOWN LEAKING AND EXPELLING OF HAZARDOUS ANTI-FREEZE/COOLANT ON ROADS BUT ALSO LEADS TO THE UNREALIZED OVERHEATING OF ENGINE. THIS CAN LEAD TO UNNECESSARY ENGINE DAMAGE FROM SIMPLE OVERHEATING OF OIL TO THE EXTREME OF BLOWN HEAD GASKETS, BLOWN/BROKEN CYLINDER RINGS, WARPED ENGINE HEADS OR COMPLETE ENGINE SEIZURE. CHEVY RETAILS THE NEW METAL PART FROM $82.00 - $95.00. THIS FAILING PART WAS KNOWN EARLY ENOUGH THAT THE NEW PRODUCT HAD ALREADY BEEN MADE AND DISTRIBUTED TO DEALERSHIPS. WEB LOGS ARE FULL OF THIS PARTICULAR FAILURE, ON THIS VEHICLE. *TR
WHILE DRIVING DOWN HIGHWAY I HEARD A CLUNK IN MY DRIVER SIDE DOOR. WHEN I GOT TO MY WORK AND GOT OUT TO LOCK THE DOOR, THE LOCK HOLE WAS EMPTY. *TR
THIS MORNING AT WORK, I GOT OUT OF MY 2005 CHEVY AVEO AND SHUT THE DRIVER'S SIDE DOOR AS USUAL. I HEARD A "PLINK" NOISE, AND DISCOVERED THE DOOR LOCK HAD COLLAPSED INTO THE INSIDE OF THE DOOR. I DON'T SEE ANY RECALLS ON IT, BUT I CAN'T HELP BUT WONDER IF ANY OTHER AVEO OWNERS HAVE HAD THIS EXPERIENCE. *TR
