Hi Sknz. The first thing to look at and have checked in these situations is a failing battery. Is your Fusion still within the 3 year/36,000 mile Bumper to Bumper Warranty? If yes, make an appointment with your Ford Dealer's Service Department and bring it in for proper diagnosis.

The short explanation is that modern cars are heavily computer/electronic and electrically dependent. So a weak/failing battery does not give enough power on startup, causing the diagnostic checks to give false readings. Either way, checking the battery would be the first thing to do. And it needs to be properly load tested. An old fashioned battery test will often show the battery is good, when it is not.

Let us know how you make out and good luck.

I had a bunch of crazy codes on my 2018 sport and it turned out that mice or some kindof rodents had started munching on the wiring harness going across the engine right under the big plastic V6 engine cover. The wiring covers in new cars is made from soy based products to be environmentally friendly but it is a double edged sword because it attracts wildlife. My car had sat for a few weeks while I was on business. About $600 repair.

I never got any codes when I went through 5 batteries in a course of a few weeks. Could be something wrong with the ECM.

If you do find rodents have done damage be sure to check with your insurance company because we were surprised to learn that ours covered the repairs. We were glad the dealer service manager asked us if we had filed a claim or we would have never thought about it!
