I had an '18 and '20 that "shuddered" at the first stop light in the morning and rarely at other times. '20 still does it after cam phaser re-program and repair (63k miles), '18 cam phasers replaced twice. Not unusual, doesn't hurt anything except when the wife is with me and asks me "What was that?" and I'd say "normal". She finally stopped asking me.. It's an included Raptor feature.
