2022 Toyota Mirai

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2022 Mirai.

The 2022 Toyota Mirai represents the highest-complaint year in the model's documented 2016–2025 history, with 10 total owner complaints lodged against it — a sharp contrast to the model's low of just 1 complaint in 2020. The primary concerns cluster around Vehicle Speed Control and Forward Collision Avoidance systems, and the year carries a single recall alongside those complaints. For researchers mapping the Mirai's reliability arc, the 2022 model year sits squarely at the peak of owner-reported issues, signaling that this particular year warrants the closest scrutiny when evaluating the model's overall track record.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Across the Mirai generation, federal complaints remained relatively low from 2016 through 2021, never exceeding four annually, but the 2022 model year represents a stark spike with 10 complaints before dropping to six in 2023 and zero thereafter. Recalls began an upward trend starting in 2021 with one, holding at one in 2022, and increasing to two in both 2023 and 2024, which implies that the problems surfacing in 2022 may have prompted further regulatory attention. The 2022 model sits at the apex of this complaint arc, with its issues heavily concentrated in Forward Collision Avoidance and Vehicle Speed Control systems, resulting in two crash-related complaints. Because the federal data does not specify the root causes for these specific failures, the elevated risk is difficult to independently mitigate. Given that 2022 is a clear anomaly for complaints within this generation and carries documented crash risks related to its collision avoidance systems, prospective buyers should exercise strong caution and ensure all related recalls and software updates have been fully resolved before purchasing.
