2020 Expedition occasionally doesn't start

[Nick Kory]

Hi, just bought a 2020 XLT. Occasionally (and generally when in a hurry), the car won't start. Press the ignition button and lights flash, headlights flash, but nothing turns over. 15-30 min later, starts right up. Happens once a week, maybe less. Saw some threads on internet that this has happened before and could be related to anti-theft system. Any ideas on what I should tell dealership?

We've also had a fair share of strange issues on here related to dead or dying batteries. Even brand new 2020's end up having dead/crappy factory batteries. Just a thought as it sounds electrical most likely.

Battery - and/or loose or corroded battery terminal connectors.

Never had an issue with our 2019. But its easy to fail start hitting the button before pressing the brake. Could also be as simple as a bad brake pedal switch.

Did you find a resolution? My 2020 does the same thing

I have the reverse of this - every now and again my truck won't actually shut down. I press the button to turn off and nothing happens. I reported this on my warranty service back in February but they were not able to replicate of course. I need to catch it on video...

Did you find a solution to this problem? My car does the exact same thing and I’m at my wits end with it!

It has not happened for a couple weeks
I did.charge my battery and possibly a weak battery messes with the security sytem that disables the start

We have a 2019 superduty at work that does something similar occasionally. My hypothesis is that it occurs when parked with something near the driver side rear taillight for an extended period of time. It happened to me a couple of times on a recent trip, but it only occurred when there was something very near the rear driver side taillight. In order to reset, I had to get out, lock and shut the door, then reopen.
