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.

But for some unknown reason...

Ignition switch-while driving down the road with my wife and small children, my truck shut off on its own. I tried to restart the engine and it started, but shut back off. I noticed that the ignition switch was feeling loose. This has happened 5 or 6 times in the last two days. I got online and found out that I am not the only one that has had this problem. What happens if I am driving down the road and my truck shuts off on its own and I am in an intersection? I have been a firefighter for 10 years now, I don't want to see any more unnecessary mva's happen due to faulty parts. This problem needs to be corrected asap!!!

My vehicle began having issues when attempting to start it. The vehicle would either turn over and die immediately, or not even turn over at all. This would happen a number of times before I was able to actually start the vehicle and drive it, and it happened every time I went to start it. I took it to a dealership to resolve the issue where they told me the tipm relay was shorting out causing the current to the fuel pump to be cut off, preventing fuel flow to the engine. They replaced the relay and I went about...

my day, after a steep cost for the repair. However, as I looked into this issue online, I found a safety recall for this same exact issue for the same year model vehicles, only they were dodge caravans and dodge durangos. My vehicle is manufactured by this same company as the caravan and the durango, it is the same year model that was affected on these other vehicles, but for some reason there was no safety recall for my vehicle. I am just trying to figure out why this is, and also to voice my complaint about the initial issue at hand to hopefully bring this to light.
