HELP - Check Braking System

[KDTX]

did you have any more issues with this? We just bought a 2022 2.3lbig bend bronco today and on our way less then 300 miles on it going down the highway at 75 with cruise control on as well the check brake system came on my husband said nothing appeared to be wrong but we drove to the closest dealer and now my brand new car is sitting at a dealer an hour from our house waiting for them to change the vacuum line which is what they claim is the issue. He said he had full brakes and nothing seemed like it was wrong as well.

I had the exact same thing happen to me as I was leaving the dealership with my brand new 500 mile Outerbanks. Same Vacuum line error. I went straight back to the dealer, they checked it and could only find the error codes. The light went off when I was sitting at the dealership (mad) for about an hour. I then left and said if it came back on, I would take it in to a dealer closer to my house (this dealer was 120 miles away). It came on again 20 minutes into the trip home. I used caution but the brakes were fine. The next morning the light was off. It stayed off for about 3 days and then came back on once when I was on the freeway. It went off again once I let it sit for about an hour while I was working at a job. It hasn't came on since. I would leave the dealer asap and disregard unless the problem becomes frequent. I think it is just a hose or sensor breaking in. Had my truck for about 3 weeks now and haven't had the light come back.

Well know documented problems with the 2.3’s vacuum assist brakes. These are carried over from the Ranger. Not only failure prone but also long stopping distances, poor modulation along with mushy pedal feel.

I didn’t have another issue with it and the dealer found nothing wrong.

No other warning s but the one above. I have tried cycling parking brake and traction control. I was going 70+ on the freeway when it came on.

My new bronco just did this as well did you find a solution?

I let it cool down, restarted and never see it again. Dealership found nothing.
