2013 TOYOTA AVALON HYBRID Engine Problems

I WAS PARKING HEAD-IN TO PARKING SPOT. AS I REACHED THE FINAL SPOT, AND WAS SHIFTING GEAR TO P (PARKING), THE CAR TOOK OFF LIKE A "ROCKET" AND JUMPED THE CURB. THIS CAUSED DAMAGE TO THE CAR PARKED IN THE NEXT PARKING SPOT AND MY CAR. THE OTHER CAR HAD TO BE TOWED. I WAS ABLE TO STILL DRIVE MY CAR. THIS HAPPENED AT AN OFFICE BUILDING OUTDOOR PARKING LOT. PEOPLE STANDING OUTSIDE THE BUILDING (FOR SMOKING OR OTHERWISE) WITNESSED IT ALL. THEY ALSO INDICATED THAT THE CAR WENT LIKE A ROCKET AND THEY HAVE NEVER SEEN ANYTHING LIKE THIS.

MY 2013 TOYOTA AVALON HYBRID IS HAVING ENGINE REVVING PROBLEMS. WHILE OPERATING AT NORMAL SPEED (45-50). THE RPM'S SUDDENLY INCREASE TO HIGH LEVELS WITHOUT AN INCREASE IN SPEED. LACK OF CONTROL IS EVIDENT. IF YOU SWITCH TO "MANUAL" MODE WITH THE GEAR SELECTOR YOU CAN FORCE IT OUT OF PLAY...BUT THE REVVING CAN OCCUR SOON THEREAFTER OR IT WILL NOT OCCUR AGAIN A DIFFERENT DAY. I TOOK THE CAR INTO BE SERVICED AND TOLD THE SERVICE MANAGER ABOUT THE REVVING PROBLEM. HE SEEMED TO BE VERY DOUBTFUL OF THE DESCRIPTION AND TOLD ME THEY COULD DOWNLOAD THE ENGINE HISTORY. THEY REPORTED "NO PROBLEM FOUND". IT HAPPENED AGAIN A FEW WEEKS LATER FOR A WHILE ON A FLAT PAVED COUNTRY ROAD AND COULD BE COAXED TO STOP WITH THE GAS PEDAL. *TR
