My wife's 2020 Expedition with about 80k miles has been having some odd issues over the last 2-3 months.
First, the display would be black when you started the vehicle occasionally. We had to hold the 2 buttons down (can't remember which two at the moment) until it rebooted. Refreshed the newest version of the firmware and that issue went away.
Second, the auto start/stop quit working. It would stop but wouldn't start back up until you put it in park and restarted it. It didn't do this every time, but enough to be annoying/dangerous. I tried charging the battery, resetting everything, etc and finally just bought a auto start stop Eliminator.
Now the brake warning light comes on, the brake system warning display pops up and the hill assist disabled warning comes on as well. After driving for a few mins, these seem to all go away.
Another thing it has recently started doing is the door chime sounds funny until driven for a little while, then it sounds normal again.
The last two are usually after not being driven for a couple days.
I'm thinking all these issues are pointing toward a battery trying to go out, but the vehicle starts just fine and the battery tests good with my tester. 12.4V if I remember correctly. The connections are clean and tight.
Before I dropped the money on a new battery, I was wondering if there could be something else going on or if the battery could be the culprit.
