NHTSA Complaint #11664665 — 2016 FORD F-150

After passing a car on a two lane highway 120 miles from home a wrench light came on and the transmission got stuck in 5th gear. We pulled over, stopped the truck and then it got stuck in 3rd gear and then the check engine light came on. The truck then proceeded to on into limp mode. At that point with the transmission clunking we and the truck shutting down we didn't feel safe driving the vehicle to our weekend destination nor did we feel safe driving it home as we had no idea if the transmission would completely fail. These were two lanes roads with not much shoulder and steep cliffs along the road in many areas and it was very unpopulated so any number of things could have happened to put us at risk. We had the truck towed 120 mileshome and taken to the nearest Ford Dealership, which was Larry H Miller Ford in Mesa, Arizona. The wrench and check engine light did go off but the service center was able to find the codes when they checked and it was determined to be lead frame failure. They removed and replaced the lead frame. There was no warning or codes prior to this happening - only on the day it happened.
