THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 60 MPH, THE VEHICLE STALLED AS THE STOP SAFELY NOW WARNING LIGHT ILLUMINATED. THE VEHICLE WAS RESTARTED BUT THE FAILURE RECURRED ON SEVERAL OCCASIONS. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE WATER PUMP FOR THE ELECTRICAL SYSTEM FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 14V526000 (HYBRID PROPULSION SYSTEM).THE FAILURE MILEAGE WAS UNAVAILABLE. DJR
I PULLED INTO A GAS STATION TO TURN AROUND. WHEN I CAME TO A COMPLETE STOP AND PRESSED THE GAS PEDAL TO GO, MY GAS PEDAL WOULDN'T BUDGE IT WAS LIKE IT WAS STUCK. WHEN I PULLED ON THE HIGHWAY IT DONE IT AGAIN BUT IT TOOK LONGER TO GET MY GAS PEDAL TO PRESS DOWN. WHEN I COME TO STOP NOW I HAVE TO KEEP MY FOOT ON THE BREAK AND THE GAS PEDAL TO INSURE THAT IT WILL GO WHEN I PRESS THE GAS PEDAL. *TR
ACCELERATOR GAS PEDAL DIFFICULT TO DEPRESS WHEN WEATHER GETS COLD (BELOW 50F). IT REQUIRES A HARDER PRESS TO ENGAGE AND HAVE THE CAR MOVE. IT IS DANGEROUS WHEN CROSSING AN INTERSECTION AFTER A STOP. FOR THE FAILURE TO WORK RIGHT KEEPS US IN THE INTERSECTION AS WE TRY TO MOVE OUT OF THE WAY OF ONCOMING TRAFFIC. HAVING TO PRESS HARDER RESULTS IN LOSS OF CONTROL AS WE MANEUVER THE CAR WHEN TURNING AT AN INTERSECTION. WE TOOK THE CAR TO THE DEALER AND THEY ADDED A LUBRICANT . IT HELPED A LITTLE , BUT IT WAS AGAIN DIFFICULT THE NEXT COLD FRONT THAT WE HAD (TEMPERATURES BELOW 50F). THIS CONDITION GRADUATED FROM THE FIRST WINTER WE OWNED IT IN 2008 TO THIS WINTER STARTING IN 2011. IT APPEARS THAT THE PEDAL WORKS BETTER AFTER THE CAR HAS BEEN OPERATING FOR A WHILE, LIKE 20 MINUTES OR SO. *TR
