This morning, I dropped off my 2022 Max SPP at the dealer for a list of issues - one of which is the vibrations. This would be the third time I've had it in for this. Got an Escape as a loaner and on the same roads my Expedition is shaking this thing drives smooth as glass. Night and day difference.
Also, I've found that a lot of the shaking I feel at lower speeds may be from the transmission. It shudders a lot - especially around 35-40mph in 9th and 10th gear. It's hard to discern vs road imperfections, but on roads I *know* should be smooth as glass my expedition is always shaking, bumping, or vibrating.
