Key Takeaways

  • Exceptional fuel economy (67 MPGe combined) and zero tailpipe emissions are the Mirai's main draws.
  • The severely limited hydrogen fueling infrastructure is the most significant barrier to ownership, restricting practicality to specific geographic areas.
  • The automatic emergency braking (AEB) system is a critical concern, with reports of unintended, abrupt braking events.
  • A high TSB count (60) suggests potential underlying issues that may require future attention.

Overview

2018 Toyota Mirai

The 2018 Toyota Mirai is a hydrogen fuel-cell electric vehicle offering an impressive 67 MPGe combined fuel economy and zero tailpipe emissions. This front-wheel-drive sedan features an automatic transmission. However, its advanced technology comes with specific considerations for used car buyers, most notably the limited availability of hydrogen fueling stations. While the Mirai has zero recalls, two complaints have been logged concerning its service brakes and automatic emergency braking system. A high TSB count of 60 also suggests potential underlying issues that warrant attention during a pre-purchase inspection.

Critical Failure Risk

Sudden, abrupt braking events occurring without apparent external triggers. This is linked to the forward collision avoidance and automatic emergency braking (AEB) systems.

Early detection can help you avoid a $150-$500 repair.
