NHTSA Complaint #11486797 — 2021 FORD EXPEDITION

I am concerned about the shifting or transmission in my new 21 expedition. Purchased new less than a year ago, currently less than 20k miles but the vehicle shifts gears hard, sometimes it seems it wants to up shift while in park or braking. The shift is shaky at times and I now put in park when stopped at a drive through because the last time I went to the bank while waiting with brake applied the car felt as if it was going to just drive off, I immediately put in park. This is scary because my kids rode with me and I dont want the gears to shift incorrectly and cause us to wreck. Dealer asked me to schedule a time when I can leave my vehicle for an unknown amount of time. In order to get a loaner the first available date to drop it off is November 17,22 which is over a month away.
