NHTSA Complaint #11476811 — 2015 FORD F-150

Two weeks ago my 2015 Ford F150 died in a parking lot. I drove it in fine, walked into the store, and when I left the store the truck was dead. Battery was good, alternator was good, but would not start. I had it towed to my local Ford dealer. Three days later they informed me that the starter was bad and it was replaced. Two days later I'm driving at highway speed (approx 70 mph) and the truck violently downshifts from sixth to third gear causing the tires to lock up and the vehicle to skid approx 20 ft in NYC traffic. Luckily there was no one close behind me although there were numerous car horns beeped and swerving traffic as I rapidly decelerated. The truck remained in third gear until I moved into the safety lane and the RPMs (due to slowing) returned to normal. The instrument panel only displayed a message "Contact Dealer". I shut the truck off and the turned it back on with no faults indicated and limped it home. Since then the truck has repeatedly failed to start. It will start fine for a day or two, and then nothing when the key is turned. I had it towed to my local service station where the mechanic informed me that the computer code errors indicated that there were multiple errors with the transmission. The soonest that the Ford dealer can inspect is 35 days from now. I see that earlier model Ford F150's had a factory recall for similar transmission problems. My concern is that due to electrical malfunctions within the transmission control module, Ford F150's may rapidly decelerate when the transmission inadvertently downshifts multiple gears causing accidents and possible loss of life.
