NHTSA Complaint #10419457 — 2009 TOYOTA PRIUS

RE: 2009 TOYOTA PRIUS. APPROX. 23K MILES. ON SUNDAY, AUGUST 14, 2011 WE WERE DRIVING AT ABOUT 40 MPH WHEN WITHOUT WARNING, THE CAR COMPLETELY SHUT DOWN - ALL SYSTEMS AND ALL INFORMATION DISPLAYS. IN SPITE OF COMPROMISED STEERING AND BRAKING WE WERE ABLE TO STOP CAR. CAR WAS COMPLETELY UNRESPONSIVE OTHER THAN BEING ABLE TO TURN ON HAZARD SIGNAL. VEHICLE WAS TOWED TO A TOYOTA DEALER. DEALER JUST INFORMED US THAT THE CAUSE WAS A WATER PUMP FAILURE WHICH CAUSED THE CAR TO GO INTO A "SAFE" MODE SHUTTING DOWN THE CAR WITHOUT ANY WARNING OR TIME FOR THE DRIVER TO FIND A SAFE RESPONSE. UPON QUESTIONING, THE DEALER ALSO SAID THIS WOULD ALSO HAPPEN AT HIGHER SPEEDS WHICH IN OUR OPINION, COULD POSE A LIFE THREATENING SITUATION NOT ONLY FOR THE OPERATOR BUT FOR THOSE VEHICLES AROUND HIM. FURTHER WHEN ASKED, THE DEALER SAID IT DID NOT KNOW IF THE FAILURE OF ANY OTHER COMPONENTS WOULD CAUSE A SIMILAR SHUT-DOWN. OBVIOUSLY, TOYOTA'S DEFINITION OF "SAFE" MODE IS 180 DEGREES OFF AND THIS IS A SYSTEM DESIGN FLAW THAT NEEDS TO BE ADDRESSED BEFORE IT RESULTS IN A TRAGEDY (IF IT HASN'T ALREADY DONE SO). *TR
