Looks like out of luck with dealer.

I saw that Walmart batteries are now being manufactured by Johnson Controls as of 2021. Might be giving them a try can’t be any worse than motorcraft

I have purchased Walmart's Everstart Maxx batteries on several occasions for my vehicles. They have a 3-year free replacement, and with the heat here in Vegas I find that they seldom will last the full three years. I usually get the battery replaced at no cost during that three year period. Of course, they won't replace the battery unless they put it on their battery charger/tester which take a few hours to run.
