NHTSA Complaint #10443976 — 2012 FIAT 500

REALLY COLD MORNING, UPON STARTING, THE TPMS REPORTED THE LEFT FRONT TIRE LOW ON PRESSURE. AND TIRE LIGHT STAYED ON. I HAD ALL 4 TIRES CHECKED AND FILLED TO SPECS, CONTINENTAL TIRES, BUT THE TIRE LIGHT STAYED ON FOR THE NEXT DAY AND A HALF, WHEREIN I DROVE ABOUT 65 MILES, AND TURNED THE CAR ON/OFF NUMEROUS TIMES. (AT WORK, STORE, OVERNIGHT, ETC.) THE TIRE PLACE THAT I TOOK THE CAR TOO TO HAVE THE AIR CHECKED, WAS UNABLE TO DETERMINE HOW TO RESET THE TPMS. THERE WAS NOTHING OUT ABOUT THIS CAR YET. (FYI, YOU CAN USE A CHRYSLER RESET UNIT) THE TIRE LIGHT FINALLY WENT OUT THE NEXT DAY ON IT'S OWN ON THE WAY HOME FROM WORK. WENT TO THE FIAT DEALERSHIP A FEW DAYS LATER TO FIND OUT HOW TO RESET THE TPMS IF/WHEN IT HAPPENS AGAIN. THE SERVICE MANAGER CHECKED IT OUT. LET AIR OUT UNTIL THE LIGHT CAME ON, THEN FILLED IT TO THE CORRECT PRESSURE, THEN DROVE IT ABOUT 50 FEET, AND THE TPMS LIGHT RESET ITSELF. SO, THE SYSTEM APPEARS TO OPERATING PROPERLY NOW AFTER WHAT I HAD OBSERVED. WILL WATCH TO SEE IF IT BECOMES A PROBLEM. *TR
