"Park Brake Limited Function, Service Required" after truck rolls backward toward a drop-off

[KenE]

2023 Hybrids do not set the parking brake automatically. Tried it on a steep side street after another thread about it being automatic.

I also made a video of it not happening. My proof.
Same Hill. Watch the drive indicator as I shift to park. I then open the driver's door. NO automatic parking brake activated.

2025 change to the software?

Mine is early 2025 AWD Hybrid, & I don't recall EPB engaging automatically on a slope. I did have the Park Recall done. Advice from Ford, always engage the EPB first, especially prior to having the software recall completed. Procedure, after stopping, still ON, foot on brake pedal, shift into neutral, engage Parking Brake (yes you can hear it), release brake pedal & verify Parking Brake keeps truck from moving, then press brake pedal, shift to Park, turn switch off.

Ken,
I posted about doing this same procedure that you posted about back in 2024
