NHTSA Complaint #11572429 — 2022 FORD F-150

While coasting to an upcoming stop downhill, on slightly graded slope, speed within 15mph or less, with brake slightly applied; the Automatic Parking Brake engaged on its own, subsequently resulting in the transmission shifting of drive modes to park automatically. The vehicle came to an instant, unexpected stop, while still maintaining a speed around 5mph on its own. The vehicle locked up mid-line-of-traffic, leaving the potential of a rear-end collision by following vehicle. No known damage to transmission or powertrain resulted. Adverse weather/road conditions did not play a factor at the time of incident. Incident has occurred multiple times prior, during similar environment & circumstance.
