Have a 2020 2.4L and probably do not drive it enough (didn't foresee that I would be still working at home so I have 5,700 miles in nearly three years.) The auto start stop has rarely activated and once, it went into battery saving mode with the result that the only door that would lock/unlock was the driver's. I bought a battery charger. It would take a very long period to charge the battery. The auto start stop would work after charging on only the first trip. At stop lights info screen said battery charging. I was out of town and rented an Explorer with 45K and it had no problem with the auto start stop. The Ford Dealer said the battery was good and that I needed to brake harder. Had it tested and results were 503 CCA and 12.37 voltage. Even if the dealer said battery was no good, I would get only five percent proration if I bought a new Motorcraft battery. Researched sites (like Consumer Reports) said the Diehard Platinum AGM was the best battery available. It is sold at Advanced/CarQuest Auto Parts with free installation and if they install it, you get a 36-month full replacement warranty, plus jump service, towing and more up to $125. Also, if more than 100 miles from if you need assistance and must stay overnight, you can claim up to $250 for meal and lodging expenses. The battery is one thing that I would recommend not buying OE from Ford Dealer and also not trying to squeeze every last volt out of a battery unless you have a good set of jumper cables.
