:Some engine designs use a rubber belt—rather than a metal chain—to drive the oil pump. This belt operates submerged in engine oil and may wear out prematurely, potentially leading to a sudden loss of oil pressure. Additionally, they have released transmission systems in certain ''Fiesta'' and ''Focus'' models that have experienced issues, including loss of power during acceleration, gear shifting, or at constant speeds, as well as unintended acceleration. It has been reported that a software update rendered a vehicle inoperable.<ref>https://garagewire.co.uk/news/bbc-watchdog-ford-ecoboost-wet-belt-problem/</ref><ref>https://www.freep.com/in-depth/money/cars/ford/2019/07/11/ford-focus-fiesta-transmission-defect/1671198001/</ref><ref>https://www.fordraptorforum.com/threads/automatic-software-update-bricked-my-truck.96624/</ref>

:Ford has had the highest number of vehicle recalls in the U.S. in 2021, 2022, and 2023. While recall volume can be influenced by market share, larger automakers often have more recalls, it may also reflect differences in production quality compared to competitors.<ref>https://datahub.transportation.gov/stories/s/NHTSA-Recalls-by-Manufacturer/38mw-dp8u/</ref>
