I WAS RUNNING ERRANDS WHEN STEAM CAME GUSHING OUT ON MY PASSENGER SIDE IN THE HOOD AREA. I PULLED OVER TO DISCOVER THAT MY THERMOSTAT HOUSING WAS BROKEN AND MY THERMOSTAT LAYING ELSEWHERE IN THE CAR. I SEARCHED THE INTERNET AND DISCOVERED THAT THIS IS A WELL-KNOWN PROBLEM. THE CURRENT THERMOSTAT HOUSING IS MADE OF PLASTIC. THE DESIGN IS SUCH THAT THE ONLY THING THAT WAS HOLDING THE THERMOSTAT IN WAS A SOUND WELDED PLASTIC SEAM. I HAVE ORDERED A NEW METAL HOUSING WITH AN IMPROVED DESIGN.

I HAVE JUST OVER48,000 THOUSAND MILES ON MY 2005 CHEVY AVEO HATCHBACK. THE THERMOSTAT HOUSING UNIT ON THIS VEHICLE IS MADE OUT OF PLASTIC. OVER TIME IT WILL WEAR DOWN, AND EVENTUALLY CRACK. AS A RESULT, THE ENGINE COOLANT WILL LEAK OUT AND YOUR ENGINE WILL OVERHEAT. IT IS NOT PART OF THE POWER TRAIN WARRANTY COVERAGE AND WITH TAX THE REPAIR RAN $312 DOLLARS. THIS IS FOR A DESIGN ISSUE WITH USING HARDWARE WITH A PLASTIC HOUSING. THE DEALERSHIP KNOWS THIS ISSUE EXISTS AND THAT YOU'LL HAVE TO COME IN FOR REPAIRS EVENTUALLY. LUCKILY I WASN'T ON THE FREEWAY WHEN THIS HAPPENED AND TRAVELING AT LOW ENOUGH SPEEDS TO MAKE IT HOME SAFELY. I THEN HAD THE CAR TOWED TO THE DEALERSHIP FOR REPAIRS. THE AUTOMOTIVE REPRESENTATIVE ADVISED THERE WASN'T ANY REAL WAY TO AVOID THE INCIDENT WITH ANY PREVENTIVE MAINTENANCE. I SAID IT WAS NOTHING THAT I DID WITH THE USE OF THE VEHICLE. IT WAS A MATTER OF TIMING, THE SUMMER HEAT CONDITIONS AND THE FACT THAT THE ORIGINAL THERMOSTAT COMPONENT HAS A PLASTIC HOUSING. HE STATED IT SHOULD NOT HAPPEN AGAIN AS THE REPLACEMENT THERMOSTAT WAS OF DIFFERENT CONSTRUCT AND WAS NO LONGER PLASTIC. *TR

2005 CHEVY AVEO I BELIEVE MY ACCELERATOR BECAME "STUCK" WHILE DRIVING ON THE INTERSTATE - CANNOT CONFIRM BUT WHEN I WAS EXITING, IT WAS EXTREMELY DIFFICULT TO STOP AND WAS REDLINING WHILE AT A STOP. I TURNED THE CORNER AND THE CAR ACCELERATED UP TO 50 WITH NO FOOT ON THE ACCELERATOR NOR ON THE BRAKE. (50 WAS AS I WOULD "LET IT" GO). I WAS ABLE TO MAKE IT HOME, BUT REDLINED AGAIN WHEN I PUT IT IN PARK. WAS TO TAKE IT IN, REDLINED IMMEDIATELY AT IGNITION. MY DAD SLAMMED ON THE ACCELERATOR PEDAL AND IT STOPPED. HE DROVE IT TO THE MECHANIC, AND SAID IT DROVE "FINE." THE MECHANIC WAS UNABLE TO RECREATE THE SCENARIO AND SAID THE COMPUTER DID NOT REGISTER A PROBLEM AND THEREFORE THEY ARE UNABLE TO FIX ANYTHING UNTIL IT HAPPENS AGAIN OR GETS WORSE. DROVE THE CAR ON SHORT DISTANCES AGAIN FOR LESS THAN A WEEK. AT THAT TIME, THE BATTERY LIGHT CAME ON AND STEERING WAS HORRIBLE - (POWER STEERING OUT?) MADE IT LESS THAN 10 MILES HOME, WHEN THE CAR DIED. WOULD NOT TURN ON, MADE CLICKING NOISE. TRIED CHARGING THE BATTERY, WAS ABLE TO MAKE IT TO THE MECHANIC AGAIN...WHERE THEY SAID A BELT HAD FAILED. IT'S THE BELT THAT AFFECTED THE ALTERNATOR'S ABILITY TO CHARGE THE BATTERY AND THE POWER STEERING. THERE IS ALSO A TRANSISTOR THAT WENT BAD. RELATIVELY CHEAP TO FIX, BUT I HAD MY 1 YEAR OLD SON IN THE CAR WHEN THE CAR WAS ACCELERATING ON IT'S OWN. NOT SAFE! OTHER THAN THAT, I HAVE NOT HAD A SINGLE PROBLEM WITH MY AVEO. *TR
