NHTSA Complaint #11686094 — 2020 FORD F-150

The transmission failed. While driving, it shifts extremely hard and will suddenly downshift without warning. Autonation Ford of North Canton, Ohio, inspected the vehicle on August 13, 2025, and reported that the CDF drum clutches were likely worn. The truck is available for inspection upon request. The sudden downshifts cause the truck to jerk violently and lose speed abruptly. On multiple occasions, this has nearly caused me to lose control and creates a high risk of being rear-ended by other drivers who are not expecting the sudden slowdown. Yes. Autonation Ford of North Canton, Ohio, confirmed the issue on August 13, 2025. Yes. Autonation Ford of North Canton inspected the transmission and stated it was likely due to worn CDF drum clutches. There were no warning lamps or messages. The symptoms began before August 2025 when the transmission started slipping, shifting hard, and then downshifting unexpectedly. The issue occurred just one month after the warranty expired. The dealer quoted me approximately $7,000 to repair it. I have read that Ford has replaced the old pressed bushings in this part with welded ones to prevent this failure, which suggests this may be a known defect in the original design.
