While driving, my dodge shut off and it was hard to control my vehicle and come to a safe stop, out of the way of other motorists. Lost all power, as if I turned the key off while driving. Turns out that there is a weak/loss of connection in the WIN module. while the vehicle is running at idle, the truck will shut off as if I turned the key to the off position. This is dangerous and scary. There was no warning or heads up or any issues prior to this incident.

On nov 23 2019, while I was driving my truck it suddenly died. I pulled over and started it again. This happened 2 more times that day once on the highway. Since then it has worked intermittently with the issue happening while in motion and also while stationary. I did some research and found out that I'm not alone with this issue. I have read several forums with a lot of owners complaining about the ignition module, win. Clearly this isn't a couple isolated incidents and needs to be addressed by ram. I would find it hard to believe that a total loss of power due to a faulty win that has been recognized as an issue and modified in newer vehicles wouldn't be a safety recall. From what I gather this particular win is able to get dirty on the circuit board thus causing a failure in the connection and ram knew about the problem.
