NHTSA Complaint #11645382 — 2018 FORD F-150

This has now happened 8+ times. While traveling on the highway towing either a boat or trailer, my engine shuts down. This has happened at 75 mph. The error code :Auto StartStop Shift to P, then Restart Engine" displays on the instrument panel. Power steering does not work, steering becomes quite difficult. I have found several other instances of this same issue in Ford forums. So... at 75mph, on a highway, I lost all power 3-5 times in one trip. Each time I coasted to the safety strip, put the truck in park, and restarted. Several times the vehicle would not restart immediately. I pulled off the highway and did some research and disables the Auto Start/Stop feature, which seemed to alleviate the issue. Unfortunately I cannot permanently disable the feature. I did stop at a Ford dealership and showed them a picture of the error code. The dealership did not have a fix, and stated it was not a known issue. The last instance was in November, I have not towed since then. Today another mechanic flashed the PM module that controls Auto Start/Stop for another issue, an emissions recall, but did not know if that update would also clear up the towing issue. I have found at least 5 other instances of the the same issue with other Ford F150s in online forums.
