I have a 2022 1500 Night Edition Laramie 4x4 with a 5.7 E-Torque. I have heard a bass rumble periodically that I can't identify, help.

As mentioned above i get a Bass rumble periodically. It doesn't seem to happen when I do anything like acceleration or braking.

Has anyone else noticed this and found an answer?

It is when your 8 cyl turns into a 4 cyl. MDS. Mine does this. I am surprised when it is on 4 cyl the sound is deeper(bass). Watch you green ECO light on your dash. When it comes on is when you will hear this low bass noise.
