NHTSA Complaint #11639216 — 2019 FORD F-150

vehicle started @ around -15 F, drove it for 15 minutes, parked and turned it off. 90 minutes later with temps around -5 to -10 F it would not turn over. Messages on dash included : full accessory power available, and something about a steering assist fault. Jumping battery did not help. Vehicle hauled to shop. Shop disconnected battery and reconnected it and vehicle started. Fault codes were cleared and vehicle ran without creating new fault codes. If this fault had occurred in the middle of nowhere without assistance available the computer going into no start mode when the battery was not dead could easily have resulted in death from the cold weather. The vehicle computer should have a reset option which can be triggered by any operator.
