We recently had a problem with our 2018 R/T. I was driving along going about 30mph and the car just suddenly turned off. I coasted over to the side of the road and put the car into park and restarted it after a couple of tries. It ran for about 30 seconds then turned off again. All kinds of warning lights showed up on the dash. I restarted it again and it ran for about a minute then died again. Finally was able to make to a parking lot, called AAA and had it towed to a dealer. Check engine light stayed on while I was driving it. After towing car to dealer, they couldn't duplicate the problem the next day. No code, no nothing. They tried for 3 days to duplicate the issue but no luck. I picked up the car today and drove it home no problem except it said "key fob battery low". Is it possible that that was causing the issue all along?
