Sorry if this a repeat topic, I have a 2022 2500 AT4HD. Almost every day as I head to/from work my auto headlights and my lane departure systems quit working, sometimes they turn back on, then turn off again. I thought maybe I was location, maybe weather, but it’s not. Has this happened to anyone else? Thanks ..read more

Should i be considering getting into the valvetrain or should I just drive since the noise appears to be gone? Am i doing... Read more ..read more
