Recently I am experiencing dead battery for my 2021 F150. The truck is only four months old with less than 11k miles, yet twice in the last week battery is dead. In doing some researching around it seems that others are also experiencing the same phantom drain. Some have suggested that a software update is needed. Obviously I am deeply concerned.

I thought I read a post that it was determined that a rear door was not closing properly and needed adjustment to stop the drain. I believe this was in one of the other bigger posts relative to this same subject??

That's interesting because my door appears to close completely. I had not seen that... Thanks that gives another angle to consider

Make sure you have zone lighting off. And...give your dealership service dept a call

Like mentioned above, turn off zone lighting. Ford sent out a message to turn off the zone lighting, you know an option you paid for, to prevent to battery drain. That was months ago and Ford hasen’t bothered to communicate with its customers further about this issue.
