2025 Ram Laramie hurricane 3 valve misfire software issue

[Ronny208]

Does anyone else have this issue? Apparently some Ram's have it and some don't. Service Manager says engineers are working on it. Engine runs rough and then the engine light comes on.

Yes check out this thread.

2025 RAM 1500 BIGHORN 3.0 I HURRICANE twin-turbo, SO, 420HP - check engine light

My example is an extreme example and it is contaminated, you would be surprised how many people do what I said on accident. We see "contaminated fuel" enough to have storage tanks for it. Usually water/unknown fluid in fuel. It happens, just because it hasn't happened to you doesn't make it not...

Yup, check engine light 3x for misfires and dealer says they are working on a software fix. That was 2 weeks ago. Haven’t heard any updates.

Yes, I have this issue. The dealership cannot find a solution. I also have trouble with fast idle on cold start where it doesn’t sit at a single RPM but varies up and down until the engine is warm. Is this normal?

I have a new truck with the Hurricane that also surges RPMs during warm up, have you found any info on the problem?
