Recently purchased a 2019 expedition platinum. When initially pressing the gas between gears 3-5 it frequently seems to completely lose power for a few seconds and stops accelerating. Since this occurs when initially pulling into a street or highway, it is very noticeable as I have to step on the gas rapidly to avoid an accident. Took to dealer and told normal on the new 10 speed transmission. Always owned f150 previous to this vehicle and never had issues with acceleration.
