Like others with Ford Fusions, many different years of this make and model have battery discharging problems. All engines and years. Mine is one battery number 2 and it is doing the same thing that it did with the first battery. Battery is dead after car is sitting for a couple of days. Jump start it and it will get me where I need to go. But if I only run it 30 minutes or less, it will not restart. If I remember, I have to put it on a 2amp trickle charge. But even that charge level will not keep up and the battery still discharges until dead.

What makes this so sad is that this 2019 Fusion is my newest car. My 2004 Ford Escape and 2007 Subaru Legacy make this Fusion look like the POS that it is. Both of these vehicles can sit, outside, for about two weeks without moving or starting and they will both start right up. That's sad Ford!! Newer definitely is not better in this case.

FORD needs to have at least a TSB on this issue with all the cars involved with batteries that go dead in a couple days without driving them.
