17 month old 2021 F 150 King Ranch has Required 3 NEW Batteries

[Linven]

It actually took them a day to load a bunch of updates to modules. They say this will solve our problem. It works now, although we have not traveled anywhere requiring us to tow the vehicle. Hopefully, it won't be a problem. But if so, will see what happens next.

And yes, when towing, we follow the complete procedure outlined in the manual.

My 21 Ecoboost started this before I traded it in for my 22 Powerboost. Had 9000 miles and they just replaced the battery but didn’t act like they wanted too. As soon as the battery was replaced the start/stop started working again.

I have a 2021 lariat and my auto start stop stopped working thankfully after going to the dealership they found that my battery was bad and replaced it under warranty. I am just wondering how many of these I’m going to have to replace before my warranty expires.
