Overview

2021 Toyota Mirai

The 2021 Toyota Mirai is a hydrogen fuel cell electric vehicle (FCEV) with impressive 65 MPG combined efficiency. Its advanced powertrain provides a smooth, quiet ride. However, the Mirai's viability as a used purchase is heavily dependent on the availability and reliability of hydrogen fueling infrastructure. With 10 recalls documented, primarily for the ESC system software, potential buyers must factor in the risks associated with this niche technology and its limited support network. The potential for high fuel costs is mitigated by its efficiency, but the limited fueling network remains a critical consideration.

Critical Failure Risk

The ESC system may fail to re-enable automatically after being manually disabled, potentially compromising vehicle stability control in critical situations. This is addressed via a software update to the Skid Control ECU.

Early detection can help you avoid a repair of about $0.
