parking brake fault when I get in the car? happened twice now

[Ares]

I open the door, before I start it, theres a rapid beep and a red "parking brake fault" message. which then goes away when I start the car... and I did not have the parking brake set, but maybe it sets it automatically when I park?

it happened the first day I had the car and I freaked out but it didnt happen again until today, a month later. It was frigid both times, Im up in michigan, it was like 10 degrees today.

anyone had this? I know dealers typically struggle to diagnose random issues that dont present regularly, I dont want them to start doing exploratory surgery.

Just something to check here. This is one of the errors I was getting when I had issues. They think it's a bad wheel speed sensor. I'd think you'd also have the rest of the errors also but I'm no expert.

@Ares Any update on this? I've gotten this same error twice now as well. First time was about a month ago, then again over this past weekend. Both times it went away when I started it up, and the parking brake was not on either time.

It honestly seemed like it was triggered both times by me and one of my kids opening the driver door and the rear driver side door at the exact same time, like it was an electrical pulse coming from the auto window drop. But that might have just been coincidence.

Taking it to the dealer tomorrow, been getting errors more frequently lately. There's clearly something going on with the brake, I can feel a clunk in the pedal when it has the error.

Dealer apparently found a ssc(?) Something like that, i guess its a known possible issue that presents with a brake fault. If that's the issue, it's a bad/loose connecter. They will troubleshoot and I'll find out in a few days.

Luckily they actually put me into a rental for the interim. I'll update when it's finished

I'm months away from receiving my car but I've already read handful posts in regards to this issue. I hope they fix it over the update or do a recall soon.

Thank you, yes please keep me posted.

mine has shown the fault message 3 times in the last month.

 

[Ares]

this was the conclusion. You can see the SSM 50148 they reference, but it will take a few days to see if the error is really fixed

happened to me twice so far since August ... both times i was distracted checking my emails and the car was idling for 5 minutes or so ... E-brake came on and would not go away .... turned the car off both times and waited a minute ... when i fired it up the warning was gone but it was REALLY hard to get the gear out of park and when i did i heard a loud thump ... hasnt happened in a month or so

There is also this Brake System SSM for those with the 2.3:

SSM 50314 - 2021 Bronco - 2.3L - Illuminated Brake Warning Lamp And/Or Brake System Warning Message – DTC P050F Set In The ABS Module And Firm Brake Pedal

Some 2021 Bronco vehicles equipped with the 2.3L engine may exhibit a red brake warning lamp and/or brake system warning message in the instrument panel cluster (IPC) with a diagnostic trouble code (DTC) P050F in the anti-lock brake system(ABS) module and a firm brake pedal. This may be due to contamination in a brake booster vacuum line. To correct this condition, replace the vehicle's vacuum hose (MB3Z-2420-A). Refer to Workshop Manual (WSM), Section 206-09 for installation instructions. For claiming, use casual part 2420.

Update, 3 days later, I got the full error again, so whatever they did to "secure the connector" did not do it.

Ask them to replace the parking brake button. It’s likely shorting itself.

Went in for an oil change and tire rotation and when i opened the door alarms started going off…they’re looking into it now.

Update on mine…got it back today. They replaced the brake switch. It works, no alarms. However i noticed the weird noise it normally does when engaging and disengaging disappeared…is that a bad thing?
