2021 Ford F-150: engine and transmission complaints
HIGH COMPLAINT SIGNAL
49%
561 of 1,134 relevant owner complaints are about the engine, transmission or fuel system
49% of relevant owner complaints filed with NHTSA on the 2021 Ford F-150 are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 63% of the 1,230 model years we track (2010–2023).
Excludes 119 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 45%).
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Last Monday, I was driving [XXX] near Jacksonville, Fl. While in an outer lane the truck pulled to the right during rain, not like a hydroplaning. I could not regain control and hit a barrier.

I’m concerned about the 1080R transmission CDF drum issues that ford had on these year models.Mine is downshifting hard at times not every gear but more between 5-8 gears, or especially coming to a stop light it will down shift hard from 3rd to 1st. Shifting up is not as bad as the downshifting but it still does shift …

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2021 Ford F-150
Ask the seller whether the transmission has ever been repaired or replaced, and whether the car has shown shuddering, slipping, delayed or harsh shifts, or a whine at speed.
Drive it from a cold start and long enough to warm up. Many transmission faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the transmission.
29 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A transmission already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
