2020 Explorer ST

Personal experience and opinion. When the app starts saying it's disabling features to save the battery, make financial plans, and grab a new AGM when you can. Go to a reputable dealer in town that changes it for free too!

I see it may not have fixed the other issues, but I have tested the battery after the app started that, and they were borderline.

I had over a hundred of those warnings in 3 months before the dealer decided it was the battery., But it wouldn't start being the final straw.

I replaced the battery and it didn’t fix any of the communication errors. I actually got to the root cause. The ground on my AWD module is failing intermittently. I verified it with a multimeter and looking at the oscilloscope on forscan. I have a whole thread about it in case anyone else sees these posts.
