Versions

NHTSA's VIN data lists no trims for the 2021 Mirai, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.

Problems owners report

Owners have filed 1 complaint with NHTSA about the 2021 Mirai. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year

Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.

Recalls

NHTSA lists 1 recall campaign for the 2021 Mirai over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Electronic stability control (ESC): control module

NHTSA campaign 22V239000 · reported Apr 13, 2022 · 458,110 vehicles potentially affected

Toyota Engineering & Manufacturing (Toyota) is recalling certain 2022 Lexus LX 600, Lexus NX 350h, Lexus NX 450h+, Toytoa RAV4 Hybrid, 2021-2022 Lexus LS 500h, Toyota Mirai, RAV4 PRIME, Sienna, Venza, and 2020-2022 Toyota Highlander Hybrid vehicles. The Skid Control ECU software may not turn on the Vehicle Stability Control (VSC) system when the vehicle is restarted after the driver has disabled the VSC system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, "Electronic Stability Control Systems."

Risk: Driving with a deactivated stability control system increases the risk of a crash.

Remedy: Dealers will update the Skid Control ECU software, free of charge. Owner notification letters were mailed May 27, 2022. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 22TA03. Lexus' number for this recall is 22LA01.
