NHTSA Complaint #11714693 — 2025 FORD BRONCO

Loss of braking. Note weather was cold in single digits Fahrenheit and midly snowy. I drove my 2025 Ford Bronco that was purchased in Octorber about 20 minutes to drop off my child at daycare. Going into the daycare I turned to Slippery/4A mode. After about 5 minutes inside I pulled out and switched back to Normal/2H mode. Less than half a mile later I got multiple warnings that the brakes, EBB, collision detect, and ABS had faulted, and I should service now. I only had the electronic parking brake available. I was able to use it and engine braking with my manual transmission to get to off the road to a parking lot, although I did also receive a parking brake overheat fault the turn before getting into the parking lot. I shut the vehicle off without the parking brake on. I turned it back on and the dash warning lights all disappeared after a few seconds. Brake function returned and I drove it to a Ford service center about 1 mile away. They were not able to reproduce the problem or find any DTCs. I did get notifications of some of the faults to my Ford app on my phone. I am uploading the redacted RO and screenshots of the Ford notifications. Losing braking obviously put myself and my passenger pregnant wife at risk. Thankfully I was moving at lower speeds on a flat section of road and not taking a highway exit at the time of failure.
