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. Airbags deployed. After, I got out saw the rear passenger tire was somehow off. When PSA arrive they found it 200 feet down the road. It had snapped off. Complete break at the axle hub. Given the recall issued on 2023-2025 models I thought I should report this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ford F-150 Supercab Diesel verdict →
