THERE IS NO THERMOSTAT GAUGE IN A 2003 TOYOTA PRIUS , THE CAR OVER HEATS AND YOU DON'T KNOW UNTIL YOUR IN THE MIDDLE OF TRAFFIC NEARLY GETTING KILLED. TOYOTA WAS CONTACTED, BUT SAY NOT A RECALL AND THEY DON'T HONESTLY CAR CAUSE CAR IS OLD . THAT'S NOT RIGHT , ANYTHING YOU STILL USE FROM CARS OR EVEN MEDICINE HAVE LATER COME BACK TO HURT OR KILLED PEOPLE. THERE IS NO HOT TO COLD GAUGE IN THE CAR , 2003 ONLY . I HAVE INVESTIGATED AND SEE PEOPLE PUBLISH ABOUT THIS BUT LET IT SLIP BY . I WAS DRIVING WITH NO INSTALLED GAUGE AND SURVIVED THROUGH MAKE A LEFT HAND TURN ON A STALLED VEHICLE THAT OVER HEATED AND WAS LATER CHECK BY TOYOTA TECHNICIANS THAT SAID F THERE WAS A THERMOSTAT GAUGE PROBLEM WOULD OF MOST LIKELY BE AVOIDED. SOMEBODY CAN'T KEEP OPEN AND CLOSING THE RADIATOR...

MY 2003 PRIUS (FIRST GEN, FROM JAPAN), HAS BEEN THRU A FEW RECALLS - 1 WAS TO SEAL THE BATTERY BETTER EARLY ON (04ISH), THEN IT WAS GIVEN NEW PINION SHAFT NUTS. LATEST ISSUE HAS BEEN AN ISSUE ALL ALONG, JUST NOT DIAGNOSED/FIXED TIL NOW. SOMETIMES THE 'CHECK ENGINE' LIGHT WOULD COME ON, WITH THE CAR/! /TRIANGLE GRAPHIC ON TOUCH SCREEN. THIS TIME IT DIDN'T GO AWAY. LONG STORY SHORT, IT WAS THE ELECTRIC WATER PUMP THAT NEEDED TO BE REPLACED. DEALER SAID IT WASN'T CYCLING PROPERLY, LEAKING ANTIFREEZE; ALSO A BIG HYBRID BATTERY ISSUE WAS SHOWING UP, BUT THEY SUSPECTED WHEN FIXING WATER PUMP IT MIGHT CLEAR UP BATTERY ISSUE. DID RESEARCH, FOUND THIS HAS BEEN A BIG ISSUE FOR A LOT OF PRIUS OWNERS. SAW THE CONSUMER REPORTS & THIS STORY, FROM A TOYOTA NEWS RELEASE. THE FOLLOWING IS EXACTLY WHAT I'VE EXPERIENCED, & MY CAR WAS PART...

WARNING LIGHT COMES ON AND MANUAL SAYS DO NOT OPERATE VEHICLE, PARK IMMEDIATELY. THIS HAPPENED ON MY 2003 TOYOTA PRIUS IN DECEMBER. FORTUNATELY THE DEALER WAS OPEN AND WHEN REPORTED SAID IT WAS NOT A BIG DEAL, THE CARE WAS DRIVABLE AND SHOULD BE BROUGHT IN FOR SERVICE.

2003 TOYOTA PRIUS GAS ENGINE STALLED, WARNING LIGHTS CAME ON ALL OVER THE SCREEN, AND IT WOULD ONLY DRIVE ON "BATTERY POWER." AFTER STOPPING, I TURNED THE CAR OFF BUT IT WOULD NOT RE-START IMMEDIATELY. AFTER A FEW TRIES AND THEN WAITING, THE GAS ENGINE STARTED WHEN I TURNED THE KEY. DURING THE TIME IT WAS RUNNING ON BATTERY, AIR CONDITIONER WAS BLOWING HOT AIR. AFTER GAS ENGINE RE-STARTED, AIR CONDITIONER BLEW COLD AIR. TOYOTA SERVICE SAID THEY HAD NEVER SEEN ANYTHING LIKE WHAT WAS ON THE SCREEN THEY DIAGNOSED AND SAID IT WAS THE COMPUTER AND ORDERED PARTS. THEY WERE ALSO THINKING THE BATTERY HAD SOMETHING TO DO WITH IT. 1. THEY MAY NOT HAVE DIAGNOSED MY CAR CORRECTLY SINCE THEY DO NOT KNOW ABOUT THIS RECALL, AND MAY NOT FIX IT CORRECTLY (INCLUDING PUTTING GREASE ON CERTAIN WIRES). AND 2.
