NHTSA Complaint #11710642 — 2018 FORD F-150

My 2018 Ford F150 only has 30,500 miles on it. There is a well known issue with the 2018-2022 Ford 10 speed transmissions, where the CDF drum fails and causes many transmission related issues. I started to show symptoms of this failure, very rough shifts from 1-3 gear, transmission would hesitate and not shift into the next gear, sometimes it would even aggressively downshift while just maintaining vehicle speed. The symptoms quickly got worse. I ended up stuck at a light because after it turned green, my vehicle wouldnt move, and i notcied it was stuck in 7th gear. I tried to manually downshift, but it wouldnt, as cars behind me were honking at me as i held up traffic. Eventually i started to accelerate from a stop in 7th gear, and then the transmission slammed into 1st gear. I brought my truck to Ford the next morning and they diagnosed it as a failing transmission with internal issues that needed to be replaced for over $13,000 dollars, reduced to $9800. This is at just 30,000 miles. I called around to other transmission shops and found a shop that would rebuild the transmission for $5000. I picked the truck up from the dealer to bring the the transmission shop, and it was just plain dangerous to drive. It downshifted from 4th to 1st going around a turn overrevving the engine,constant delayed shifts and rough shifts. I felt very unsafe driving this vehicle in this condition. All of these symptoms are amplified when the weather is cold and the transmission is still warming up. Ford knows about this issue, and has many Technical service bulletins related to the issue and how to diagnose it. Most recent is 25-2126 which is from March 31st 2025, I actually found it on the NHTSA website. Surprisingly there were no warning lights or anything that showed up, but i know others with the same issue have received warning lights. Ford would not provide any asssistance with the repair as my vehicle was less than 2 months out of my extended warranty end date.
