2018 f150 stx twin turbo ecoboost drove an hour to work pulled up to a job speaking to someone at my window for five minutes battery died. First time. Nothing plugged in. Nothing different since I got it. Now auto start has shut off and won’t go back on.
One year old truck… still under warranty? See your dealer.
I can’t understand the description of your problem anyway.

Auto start/stop function is finicky about batteries. As Mustangman said, use your warranty.

Yup!
The vehicle’s three-year Bumper-to-Bumper Warranty should cover free replacement of the battery.
