Failure Notifications on Restart

[kiya]

Does it happen while sitting for extended periods? That seems to be the most common similarity for most of these, but I know correlation doesn't always mean causation.

Every time it's actually happened within 30 seconds of me entering the vehicle or within 30 seconds of the car shutting down from the auto start/stop.

For me it happens after driving, turning of the truck then restarting after suiting for 15 minutes or so.

So, I have had this issue with two Broncos now. My 21 badlands only had this issue when i had the doors off. It happened once the truck was off and then i went back and turned it on hours later or even next day when i started it.

Issue 2 i just took delivery of my Raptor. Ive had the raptor for about 1 week. Never had the issue. Today i have it here getting front windows tinted. Tint installer tricked windows into stay in upward position. When i went to show him the exhaust modes i started it and it set off all mentioned warning lights. Shut vehicle off and it cleared it self. All i had to was release parking brake that set itself.

Disclaimer im The GM at my Ford Dealership. Ive had 2 master tech's look at it and it shows nothing is wrong. So Im at a loss as well. If i have any updates i will keep everyone posted

IT LOOKS LIKE THERE IS A SOLUTION!

Quick update: It is finally getting looked at by the service department. Dealer said () there is a TSB related to this issue, and there is a reprogramming that needs to be completed. After a little more research, I'm assuming the TSB is SSM 50951 and that the November time frame for a software fix has been met. Text from the bulletin below (emphasis mine):



SSM 50951

2021-2022 Bronco - Equipped With Electronic Brake Booster (EBB) - Multiple Error Messages In The Instrument Panel Cluster (IPC) After Startup

Some 2021-2022 Bronco vehicles equipped with an EBB may exhibit multiple error messages displayed in the IPC followed by automatic engagement of the parking brake immediately after starting the vehicle with the doors removed or after sitting in the vehicle for an extended period of time with the vehicle off. The issue will resolve itself once the brake pedal is no longer depressed or the parking brake is manually disengaged. This may be due to the software within the anti-lock brake (ABS) module. This issue can be avoided by placing the vehicle in accessory mode for a few seconds before starting the engine. Engineering is working on improved software to correct this condition that will be available in November 2022. No repairs should be made in attempt to correct this condition. Monitor OASIS for updates.

I was sitting in the Bronco again today for 20+ mins. I opened the door quickly after shutoff so instead of waiting for time out. After about 5 mins I heard the brake lock. Then at 10 mins, I heard another mechanical sound. So, I knew I was about to get blasted with error messages. Right before starting it back up, I popped open the door again, closed it, waited for the dash to light up, I heard the brake release on its own, then I started the truck... Opening the door and allowing the electronics to 'wake up' seems to help until the TSB is rolled out.

You might want to take it in again. I got it back yesterday, and they acted on a different TSB from the one they initially referenced. I'm assuming this is the software fix since the TSB is too new to be listed on any 3rd party sites yet (or the dealership lied). See below:

Thanks for the update. This is fairly common, or it seemed to be mentioned a lot more last Spring when many of us first started having similar issues. My experience was the same - I was waiting in line to pick up my kids from school on a nice day, so I had the windows down and top off and killed the engine. I sat for 30 minutes or so and got the same failure warnings as the OP - they were also sent to my Ford Pass app. We figured out a temporary fix of simply opening and closing the door after turning off the engine, but that sucks if you're listening to music or charging your phone. I have an appointment on Monday for the windshield recall and a host of other issues, so I'll add this to the list!

Ahhh, ok.. I see, this is the only place I start the car, move to D as the line is starting to move forward and don't take my foot off the brake after the truck starts. Normally I only have my foot on the brake long enough to allow it to start. I mean, doesn't explain the software freakout, but at least why this scenario is the place it seems to happen for us.
