Overview

2021 Ford F-150

The 2021 Ford F-150 presents a mixed bag for used-car shoppers. While it offers robust truck capabilities, its reliability record is a significant concern, marked by a high number of recalls (82) and a substantial volume of complaints (1004). The powertrain, particularly issues like rear axle bolt shearing, stands out as a major ownership risk. Electrical system glitches and visibility problems also contribute to its below-average reliability verdict.
