Overview

2020 Toyota Mirai

The 2020 Toyota Mirai is a pioneering hydrogen fuel cell electric vehicle (FCEV) offering remarkable 67 MPGe efficiency and zero tailpipe emissions. However, its advanced, niche technology presents unique ownership considerations. While it has no recalls, a single severe complaint regarding vehicle speed control and loss of control demands buyer attention. The high TSB count suggests potential complexities in its advanced systems, making a thorough pre-purchase inspection crucial.

Critical Failure Risk

A single severe complaint details a loss of control during slow-speed maneuvers, resulting in unintended acceleration and a crash. This indicates a potential for critical system failures in the powertrain control software or hardware.

Early detection can help you avoid a $800-$1,500 repair.
