Now you're finally part of the Lightning owners club.
Enjoy a mediocre dealer experience, the possibility of a rental car, a new shifter/battery module/or computer, and not having your vehicle for between 2 days and a month.
Mine never leaked in the first 2 years, so that's a positive.
On the other hand, the middle tension bar rattled and was replaced, the roller shade jumped track, the accordion pieces that cover the mechanism came off about every 90 days because they're held on with the same hope that Ford used...
Do none of you "truck people" own a torque wrench? Set it to 45ft-lbs and go find out.
If its loose, make an appointment at the dealer. If its missing... make an appointment at the dealer.
BECM is the Battery Energy Control Module. Either it died of unnatural causes, or it got turned into a paperweight doing the software update from the CSP (oh no, an acronym! Customer Satisfaction Program).
Either way... not ideal, but not terrible.
To add, there's also a sizable cash appeasement in lieu of repurchase to try and right the situation while keeping you in the vehicle.
I think I was initially offered $16,000 for the ongoing battery issues in mine. As a rough number for conversation purposes.

You'd be doing everyone a favor.
Bring it back and get a loaner while they work on it. Clocks on them. At 30 total days in service, initiate a buyback. They'll offer to cut you a check for appeasement in lieu of the repurchase. You can then pick a path forward.
After enough of these, Ford might actually change something. Until...
