Tailgate problems of the 2020 Ford F-150

I have 2 major issues: 1. My tailgate keeps opening on its own. It has happened while I was driving as well as when it is parked. Damage happened to the tailgate when it opened on its own in the garage and was leaning against the garage door when my wife opened the garage door to leave in her vehicle. It also happened while driving on the highway. This issue has happened multiple times but garage issue happened this morning and will put that as the date it happened below. 2. Also the lane minding system keeps alarming telling me to put my hands on the wheel when I have never let go of the wheel in the first place - the service department told me it was because I was driving too straight, that the system wants to detect movement in the steering wheel (am I supposed to drive serpentine down the road to keep my vehicle?s alarm from going off and distracting me?). The alarm happens when I am driving on straight areas of the road. This is an ongoing issue, pretty much on a daily basis since I bought the truck.

Drove from new jersey to brooklyn, over the verrazzano parked and guess what. . . Tailgate was open with my tools exposed? heading home nice driver in tunnel made me aware the tailgate was open. Finished driving through tunnel, pulled over to close tailgate for the third time on one day.

Tailgate opens on own even while driving. No warning that it has or is open. At highway speed the tailgate has opened allowing bed contents to spill out!.
