2019 ram 2500 bighorn hemi

[Wolffin7]

Just bought a 2019 2500 6.4 hemi second Tom I went to a professional car wash and then it wouldn’t start. Had to get towed to dealer first time and reprogrammed. Second time after it’s set for two days. It started fine. Any thoughts on what the problem is dealership couldn’t find it thank you. 39,000 miles

In the 1500 there is a RF hub below the back window under the liner, if it gets wet, it can short out and the truck won't start, all sort of things stop working. If the antenna, 3rd brake light or rear window are leaking, that could cause the problem. Not sure RF hub is in the same place on the 2500.
