My 2020 ram 1500 longhorn ecodiesel was not shutting off as the push button start was unresponsive while trying to shut off. After about 30 minutes i pushed the button 10-15 times non stop and it turned off. I haven’t started it since. Its night time and the dealer isn’t open till Tuesday due to the long weekend here. What could have caused this? How to turn off the engine if the start buttons unresponsive?
