If the auto start stop system is not working in Your 2019 Ford F-150 the first thing to check is to make sure that the system is enabled. There is a switch on the dash that has an A on it with a ring around it and the light on the button should be on to indicate that the system is working. If that is on and it is still not working then that is a sign that there is a problem with the computer in Your truck. It may not be detecting when the vehicle is stopped. There could also be a problem with the battery in Your vehicle. If that is too low it will not stop automatically because it may not be able to turn back over.

The start stop system on the 2019 ford f150 is controlled by wires, if those wires are bad then it will not function correctly, likewise if the battery is low then it will not activate.
