For the last year the battery in my 2020 fusion keeps dying, if I let it sit for more than 24hrs. The dealership says I have to drive it for atleast 30mins everyday, or it will die. I told him that's rediculous. So I'm suppose to waste gas just to keep the battery from dying. He said the battery tests fine after they let it charge overnight. I said, "well no s**t!" He said Ford won't cover a new battery if they can't find a problem. Now I know some older fusions had a software issue. But has anyone else with a 2020 had a problem with their battery dying?

My older fluke automotive meter has a max/min feature where it will measure voltages (or whatever) for a long period of time, keeping track of
the max/min/average over however long you leave it. My mom's 09 grand Marq had an issue with light control module being "woken up" by something
connected to it. Car draws maybe 45 ma when module is off, but 280 ma when module is on. She is in 80's and car sits for long periods of time,
so that module coming on over and over, killed battery in about a week.

I would ask Ford if they tested amp draw, and what it is when car "goes to sleep". Typically, you get a bigger ma draw after shutting off car,
as some things like interior/exterior lights, or other things are on for X amount of time. But once all that ends (IE, car goes "to sleep"),
you should be in the 75ma (less really) range.

Ask then to measure amp draw overnight, after car goes to sleep, to see if it is drawing too much. If they won't do it, find a shop that will.
Or buy a meter that has that feature and do it yourself. You just take off pos battery terminal and put meter between battery terminal and pos
battery cable.

Last time I was at the dealership, I asked if they monitored the amp draw. They said they did, and everything was within specs. I did turn off the wifi and auto updates last week. It doesn't seem to have made a difference. I notice that the left headlight, taillight and blinker do not come on after jump starting the battery. I usually have to turn the car back off, then re-start the car. Same goes for the display screen on occasion too. I mentioned all that to the dealer and they said there might not be enough amp draw right after jump starting battery. But as long as everything comes back on, then there's nothing wrong

A good battery does not die in 24 hours, without a pretty healthy draw. So they are either lying, or only checked it for a split second.
It needs to be monitored for the entire time you would usually leave it off, until it "usually" dies.

The hybrid uses a 2.0 N/A port injection motor. Kills me you see people listing them as a 2.0 ecoboost on eBay. I had to explain this to guy that was all hell bent that the hybrid motor was the same as a Eco, just without a turbo.

So not the same, LOL!!

There was a TSB as you mention for the CD eject problem. If that TSB was properly done by the dealer, you would not be having the whirring CD eject still. Search this forum, hundreds of entries about that issue, and it being solved.

I've never understood why you can load and eject a CD, with even the ign off, but can't do anything else??

Your on the wrong forum, they only made Fusion Sports for three years, 17, 18, and 19. There's Ford Fusions forum, might have better luck there since your talking about a 2020.

You "yelling" at BOTS again . I would just assume that ALL 1-3 post newbs are BOTS, especially when they talk generic crap that doesn't
apply to out Sports.
