Oops. My mistake. That'll teach me to just scroll through the "What's New."This is in the v6 forum so presumably he is talking about vibration related to that.
Probably going in and out of MDS (cylinder deactivation). To disable MDS use the gear selector on the steering wheel after putting it in drive and press minus (-), then press plus (+) until you see gear 8 selectedMy 2019 5.7 bighorn 3.92 vibrates, I only notice it taking it easy through a town. Even my wife comments about it, so I know it’s not in my head. If I step on the gas it instantly goes away.
