2019 Expedition

[mharwardt]

First of all I want to say I like my Expedition, like the roominess, the way it drives, and everyone that has driven it does too. It has around 80,000 miles on it, bought it new and purchased an extended warranty. Sadly, it's been in the shop quite often and for things the warranty doesn't cover. Even the service writer has been surprised when it doesn't cover an item, it's the best warranty.
The last few months random warnings come up on the dashboard, then disappear. Last month a message/warning about power train came up as we were driving, seemed to be running fine, then later warning was gone. Was notified by email of the warning and it showed up in Ford Pass. I called Ford later and they said the code was dismissed later. Then again over the weekend had another warning, this time with a wrench just as I was turning off the car. It was do do with Power train again. Started it a few times, wrench still there. Started it later on and wrench gone. I was never notified of this last one and it doesn't show up in Ford Pass. What is going on?

You didn't provide a model year, but with that mileage it's possible the 12V battery is going. These vehicles have a lot of electronics in them and are sensitive to voltage levels. My generic ELM adapter that I've used for years was able to make the vehicle throw error messages intermittently. It literally took years for me to realize that was the source of the issue because the codes were so random. Try getting the battery tested or at least install a Bluetooth 12V battery monitor and check the voltage levels after the car has sat for a few days, if possible. You can also get an OBD adapter, like Veepeak or OBDLink MX and software, like Forscan or Torque, so you can pull codes yourself.

My bad, I always look for year and mileage in the body or signature. Definitely get the battery tested. It's probably near end of life if it hasn't already been replaced.
