Car stalled all of sudden with shudder on route 7 in virginia and then immediately was yaken into parking lot for safety reasons. In trying to park car would not shut off. The car was on for about fifteen minutes then randomly stopped. After another ten minutes car would not start and then randomly started. Car was ASAP driven with engine shudder back to home drivieway and parked for safety. Car now again would nit shut down and kept running. On bith times while car refused to shut down the gauge showed cehck engine eps light and indicated that car needs tk be put in park mode even though car was jn park mode. Gearbox would not shift and car did not recognize lower gear modes as it kept saying car is not in p. Dealer was contacted and they said they were closed due to weekend. Will now need to tow the car as it will not start since previous inability to shutoff probably has killed battery.
