I WAS DRIVING TO WORK INTO THE GARAGE. THE ENTRANCE OF THE GARAGE HAS A MILD INCLINE WITH A NARROW ENTRANCE AND I NORMALLY WILL SLOW DOWN SO I CAN STEEL THE CAR SLOWLY. I WAS GOING AT ABOUT 10 TO 15 MILE SPEED AND FELT A STALL FIRST AND THEN THE CAR WENT INTO ACCELERATED MODE ON ITS OWN. I FELT THE CAR WAS SHIFT TO A DIFFERENT GEAR ON ITS OWN UP TO 80 TO 100 MILES. I AM LUCKY THERE IS A CEMENT POLE IN FRONT OF ME AND THE CAR WENT RIGHT INTO THE POLE SMASHING THE LEFT SIDE(DRIVER SIDE OF THE CAR ) I HAVE TO STEP ON THE BREAK TO STOP THE CAR. IT ALL HAPPENED VERY QUICKLY WITHIN FEW MINUTES. I WAS LUCKY THERE WAS NO ONE IN FRONT OF ME AND I WAS NOT HURT. I NEVER HAD ISSUE WITH TOYOTA CAR AND THIS WAS THE FIRST TIME. I ACTUALLY HAD CAR IN THE DAY BEFORE FOR 15,000 MILES MAINTENANCE
THE DISPLAY ON THE MEDIA-CONTROL UNIT WOULD SOMETIMES GO BLANK, IN PART OR ENTIRELY. THE TOUCHSCREEN ISSUES INTERFERED WITH DRIVERS' ABILITY TO USE HEAT, AIR CONDITIONING, DEFROST AND DEFOGGING SYSTEMS. THIS HAS HAPPENED AT LEAST 30 TIMES DURING THE PAST YEAR. THE LAST INCIDENT OCCURRED ON 01/13/2021. THIS HAPPENS WHILE IN MOTION. IT ALSO HAPPENED ON MY 2017 PRIUS PRIME MANY TIMES. THIS PROBLEM HAS BEEN REPORTED TO TOYOTA BY MANY OWNERS. NO SOLUTION HAS BEEN FORTHCOMING. THIS IS THE SAME ISSUE THAT PROMPTED THE CURRENT TESLA RECALL. THE PRIUS CHAT ONLINE SITE MENTIONS THIS TYPE OF ISSUE MANT TIMES.
