MY WIFE WAS DRIVING TO THE GROCERY STORE ABOUT A MILE AWAY IN A 2005 CHEVY AVEO. WHEN SHE GOT THERE SMOKE WAS POURING OUT OF HER HOOD. UPON FURTHER INSPECTION, THE (PLASTIC) THERMOSTAT HOUSING WAS SPLIT IN HALF ALLOWING ALL THE RADIATOR FLUID TO SPILL OUT. AFTER FURTHER RESEARCH, THIS HAS BEEN A WIDESPREAD PROBLEM ON THIS CAR AND THE MANUFACTURER HAS EVEN SWITCHED TO USING ALUMINUM THERMOSTAT HOUSINGS INSTEAD OF THE PLASTIC ONES WITHOUT POSTING A RECALL. IF SHE HAD BEEN DRIVING MORE THAN A MILE DOWN THE ROAD, IT IS VERY POSSIBLE HER ENGINE WOULD HAVE OVER HEATED AND POSSIBLY WARPED THE HEADS AND DESTROYED HER ENGINE. THIS KNOWN PROBLEM NEEDS TO BE A RECALL. *TR

THEY STATED THAT I HAD IT TOWED TO A REPAIR SHOP NOT A GM DEALER. FROM THE COMPLAINTS I HAVE READ ON THIS WEBSITE, IF I HAD TAKEN IT TO A DEALER, THEY WOULD NOT HAVE COVERED IT EITHER.

DRIVING HOME FROM WORK ON 8/26/2010, THE THERMOSTAT HOUSING JUST SPLIT IN HAVE ON MY 2005 CHEVY AVEO LS. THE ANTIFREEZE SPILLED OUT AND I NEEDED TO HAVE THE CAR TOWED. THE THERMOSTAT HOUSING IS MADE OF CHEAP PVC PIPE LIKE MATERIAL AND IS IN TWO PIECES THAT APPEAR TO BE GLUED TOGETHER. A VERY LOW GRADE RISKY DESIGN IN MY OPINION. THE REPLACEMENT PART IS ONLY AVAILABLE FROM A GM DEALER AT A COST OF $98 PLUS TAX. THE REPLACEMENT PART IS MADE OF STURDY ALUMINUM. IT APPEARS TO BE A BETTER DESIGN AND STRUCTURALLY SOUND. MY COMPLAINT IS, GM OBVIOUSLY KNEW THIS PART WAS SUBSTANDARD. EVIDENCE OF THAT IS THE REENGINEERED REPLACEMENT PART. GM SHOULD HAVE RECALLED THE CHEVY AVEO'S AND REPLACED THE CHEAP/DEFECTIVE THERMOSTAT HOUSING INSTEAD OF NOT INFORMING OWNERS OF THE DEFECT, AND ALLOWING THE PART TO FAIL ON THE OPEN ROAD. FURTHER, THE COST OF $98 PLUS TAX FOR THE UPGRADED THERMOSTAT HOUSING SHOULD NOT PASSED ON TO THE OWNER/CUSTOMER. GM SHOULD REFUND THAT COST AND/OR RECALL THE VEHICLES FOR FREE REPLACEMENT. THIS IS A SAFETY CONCERN, ESPECIALLY WHEN YOU BREAK DOWN ON A INTERSTATE HIGHWAY, IN A SMALL COMPACT CHEVY AVEO, WITH SMALL CHILDREN IN THE CAR. I HAVE READ HUNDREDS OF BLOGS ONLINE OF CHEVY AVEO OWNERS THIS SAME PART HAS FAILED ON (AFTER MINE FAILED). IT'S APPALLING THAT THERE HAS NOT BEEN A RECALL ON THIS ISSUE, AND THAT THE NHTSA HAS NOT FORCED GM TO RECALL THE VEHICLES WITH THIS CHEAP/FAULTY THERMOSTAT HOUSING. IT'S NOT ONLY A SAFETY ISSUE, BUT NO ENGINE LIGHT COMES ON WHEN THIS HAPPENS, SO A PERSON CAN CONTINUE DRIVING AND CAUSE FURTHER SERIOUS DAMAGE TO THE CAR IF THE ENGINE BLOCK SEIZES UP, ETC. *TR
