There's a few variables I'm not aware of.

If this was a factory install and if the car has less than 36,000 mi / 57,000 km, I'd return to the dealer and open a case. The existing factory warranty should cover the repair. If not...

The car now has a Whipple, and I suspect an aftermarket tune or Whipple-supplied calibration.

The Hill Assist feature involves the Anti-Lock Brake System and Powertrain Control Module.

There's, "hill assist doesn't work anymore", and there's an actual warning, "Hill Assist not Available", with a message and possible stored code. There's a difference. To the former, it doesn't work per the OP. To the latter, the car recognizes the bits enabling the service are failing and has alerted the OP.

There are physical aspects of this problem and logical.

First, I'd check for any stored codes. If there are any, those could help.

Physical problems can involve anything from a low battery to a electrical connector to a failing or dirty ABS wheel sensor. Those three things are easy to check or clear. Fully-charge the battery, review connectors under hood and in the area of the ABS block, by the master cylinder. Check the rear wheels for crud, corroded or loose connectors.

Hopefully, it's something simple, like an attachment under the hood that got loose during the install.

Pivoting to the logical, no one should have a reason to go into the existing programming and change parameters related to the feature. I fail to see an advantage in doing so. But we can't discount anything, especially if an aftermarket tune is involved.

The Ford Diagnostic and Repair System software is good at touching every module on the car, confirming it's connectivity, wellness and firmware version. I don't know enough about the car if someone could hock up and check the car. It'd take only moments.

If the car has an aftermarket tune or calibration, you could still attempt a case at the dealer. If they accept the job, they could overwrite the tune during the troubleshooting process, fixing the issue, but neutering the mods. It'd be part of the discussion process with them.

If the car has a non-Whipple tune, you could reach out to the person who provided that code, to see if they could review.

Those are some general ideas. Hopefully, any of those will bring about some tells that could lead to a resolution.

Confirm the toggle? We set our favorite button as the toggle.
