Come out from store, start Bronco, error messages

I'd expect a wheel speed sensor issue related to the ambient wetness and temperature. Warranty issue.

GeoBig

Check StabilTrak, ABS light on, no pre-collision assist, parking brake failure, GOAT modes not available. Could be a red herring, but pressing the brake emits a slight "phifff" sound now too.

Less than two years old with 4600 miles. Driven like it was a collector car - no hard braking, no hard acceleration, nothing.

Conditions: slushy, snowy

4A was selected. Only used 2H up until last month.

Let me guess, once the water and slush are completely gone from the bottom of the truck it will all work again? A "sensor" issue?

Likely

Has this persisted? I have not had the brake sound but all the warnings freaking out and loss of G O.A.T. modes about half a dozen times or so no water/snow ect. Honestly the resulting limp mode is the most annoying and dangerous. I find a safe place to pull over turn the truck off and power completely down (I open and close the driver door to expedite complete shut down) count to 10 turn it on and on my way with no issues until the next time it decides it's in a mood. For smart vehicles alot of these sensors and modules seem better suited for the short bus. It's basically a computer on wheels turn it off and on again.

Apparently the wheels on the bus do not go round and round

Thanks guys for the support.

After leaving it in the garage for the last five hours, I just went out, held my breath, and started the truck -- the error messages are now gone.

I don't know if this had anything to do with it, but again, I ran the Bronco for the last year and a half only in 2H, never changing the GOAT mode nor switching to 4x for anything (never really needed to).

Starting the Bronco just now in 2H, and not in 4A like at the store earlier, may be a red herring, but I'm going to keep an eye on this.

Put it in the garage let it thaw out then see what you get. We are getting a blizzard in MI...that's 3-5 inches. I got alarms going off. Once the snow/ice melts all goes back to normal.

And just a thought…with these Bronco I would recommend periodically switching into 4H, 4L, 4A and goat modes, just because. Nothing good ever happens to a vehicle that sits. Keep all the parts moving.

I've had 3 winters with snowmaggedens and ice rink roads and zero issues during those conditions. If I ever have the gremlins in those conditions I 100% will be trading the Bronco and moving on. I got the Bronco specifically for G.O.A.T. modes and 4 wheel drive in the winters. I got sick of driving a Mustang in the winter conditions and worrying about getting hit by other drivers or getting high centered by snow. Having a 4×4 that's touted as a go anywhere do anything vehicle and having to thaw or dry it out to use it is redicoulisness.

Mine has always happened in 2H. I have used 4L and 4H and haven't had the issues while in 4x4 which is good, absolutely don't want that happening while needing 4x4 modes. I don't have 4A so I've never used that one.

Were any codes set?

Were any codes set?

This is a good question. Personally, I recommend everyone get a decent code reader, they aren't expensive and can help to diagnose things without having to run to the dealer. Personally I use the Blue Driver one. There are others that are probably more comprehensive even than it is, but for me just checking to see what's going on with my Bronco this is great and it's BlueTooth connected to my iPhone where it has an app which is handy.

What was your resolution? I have a 2021 Bronco Wildtrak 4x4,14k miles and I live in Puerto Rico(no cold weather) I have all this and more, same warnings as you mentioned but mine will not start or even turn on and slides down my driveway with both brakes engaged and the car not running.Mine was stuck in 4x4 would not go into neutral and I can get no help from Ford and I paid 90K and has been sitting in my driveway for 2 months.

I get the brake code from time to time. It happens when the driver door is opened to get in, both times. No codes given. I have Garmin that is hooked to the OBDII port and reads codes. All this started after the last upgrade from Ford. I called the desk, THEY DON'T KNOW. I wonder if some of this has anything to do with the recall I got this week for the backup camera. It's also a software issue. This recall is for over 1M vehicles, according to the news on the radio. Do they know?

Hi there. I’d like to assist with your concern. Could you please send us a DM with your VIN and mileage so I can look into this further?

Dear Ford,

The truck will be 2 years old June 8th and has 41K on it. It is a 2023 Badland, No SAS, with Lux package, front and 360 cameras. Please let me know if you are going to reject my request as it is out of warranty.

Hey guys, resurrecting this thread as this happened to me again this week.

First time: Was up in Michigan driving during that New Year's Eve snowstorm. As you may know, Michigan utterly nukes their roads with salt, so the whole Bronco had rock-hard slush frozen everywhere and was COVERED top-to-bottom with thick road salt. Next morning started it up and got the errors. Turned it off for five minutes, started it up, and the errors were gone.

Second time: Today after a thorough self-wash here in town. Drove home with the errors and let it park in the garage.

For those keeping score, this issue affects ABS, park assist, and hill climb mode, all of which error-out and remain disabled until after waiting a while and starting the truck again.

And like I mentioned last year, there is a unique and noticeable "pfiifff" sound when pushing the break while the errors are occurring (doesn't do this sound normally). Very weird.

Get yourself a code reader and see what, if any codes are popping up in the history. Lots of sensors that go bad on these bad boys. Do this prior to taking it in. And have your information in hand

Yeah, and keep in mind that salt is very corrosive, so this could be kind of tricky to track down. But some kind of sensor issue would be my first guess. Oh, and I suggest you spend the money and get a quality code reader. Some of the specter ones really are "you get what you pay for". There are some comparison video's out there on YouTube, for example:
