2021 E450, Seems driving in high wind condition triggers this event. Happened to me 3x's now, haven't reached 3k on odometer yet. Researched the condition and found this:

Stopping the vehicle and shutting it down for 1-2 minutes and restarting clears the problem and you are good to go again. I am going to throw the BS Flag on this statement in the bulletin "This condition does not create drivability concerns". When you are driving at 60+mph with a crosswind and this malfunction occurs, you will know it instantly, and while I won't say its dangerous, it most certainly was startling and a serious cause for concern when it happened for the first time, now not so much.
I live on the OBX so wind is always present as demonstrated by Wilbur and Orville.
