2023 Toyota Mirai

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Mirai.

The 2023 Toyota Mirai is a hydrogen fuel cell sedan built on a rear-wheel-drive platform, representing Toyota's continued commitment to zero-emission technology in a conventional sedan format. With only 6 owner complaints filed for the 2023 model year—down notably from the 2022 model's peak of 10—the vehicle demonstrates improved owner satisfaction compared to recent predecessors. The two recalls issued for this model year target the Fuel/Propulsion System and Forward Collision Avoidance systems, areas that have surfaced consistently across the Mirai's complaint history spanning 2016-2025. This complaint frequency positions the 2023 near the model's historic lows, suggesting that while the fuel cell technology remains relatively niche, Toyota has largely addressed the propulsion system concerns that periodically surfaced in earlier model years.

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.

The 2023 Mirai shows a moderation in consumer complaints to six from the generation's peak of ten in 2022, though it remains well above the single-digit levels seen across 2016–2021. Recalls stepped up to two in 2023, matching 2024 and exceeding the one each in 2021 and 2022, while technical service bulletins continued their steady decline to 104 from a high of 197 in 2016. The four distinct complaint categories recorded for 2023 each involve a single report and span the fuel/propulsion system, forward collision avoidance, powertrain, electrical system, and vehicle speed control; the data does not specify root causes for any of them. No crash or fire complaints were logged for the model year. The trend arc suggests 2023 sits in a transitional period where early second-generation teething issues captured in the 2022 spike are receding but have not yet reached the low complaint volumes of the first generation. This is a reasonable year to buy if you accept a slightly elevated recall count and want the improved TSB maturity of the later build.
