Have you been offroading or going through water at all?

The abs sensor connections in the rear can get gunk in them and cause this. Unclip them and have a look

Hill Start Assist failure as well

Time for a trip to the dealer, if it’s under warranty.

Yup that will be my stop tomorrow

Be sure to post the solution. I’m curious to find out what the issue could be.

This happened to me. I searched and searched and couldn't find an answer for how to reset all that crap. Then a random Instagram post came up...you'll want to see it...

So I drove it home and about 10 miles into the drive it all just went back to normal so my guess is it was the rain getting something wet but I went ahead and made an appointment with the dealer

You need to see the DTC code

there are hundreds of possible causes do those lights. While there are definitely some repeat offenders, not every case is the same

Odds are you just had some excessive wheel slip in the rain and the Bronco interpreted that as a potential broken axle — this is fairly common and once reset, everything is fine. Just an overly vigilant computer check. Low or failing battery is another common cause and easily fixed with an overnight on a trickle charger. Dirty or damaged wheel speed sensor another common offender.

But if you pull the DTC code with a OBD reader - we won’t be sitting around just guessing. If you don’t have a scan tool often auto parts stores will read them for free.
