2018 Toyota Mirai

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Mirai.

Body PASSENGER CAR

The 2018 Toyota Mirai is a passenger car that, from a regulatory and consumer-complaint standpoint, stands as one of the quieter entries in the nameplate's history — just two total owner complaints filed, split between an "Unknown or Other" leading category and fuel/propulsion issues, and not a single recall on record. Plotted against the broader 2016–2025 complaint record, the 2018 model year sits well below the 2022 peak of 10 complaints and only marginally above the 2020 low of a single complaint, making it a relatively untroubled data point in an otherwise uneven arc. For researchers, the pairing of that vague "Unknown or Other" designation with specific fuel/propulsion concerns warrants a degree of caution in interpretation, but the absence of recalls and the low absolute count position the 2018 Mirai as a useful baseline against which the 2022 spike — and the model's reliability profile more generally — can be measured.

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 2018 Mirai sits near the low‑point of the generation’s complaint curve, recording only two federal complaints—matching the 2016 baseline and well below the spikes seen in 2022 (ten complaints) and 2023 (six complaints). Throughout the period, recalls were absent until 2021, after which a modest increase to two recalls per year emerged in 2023‑2024, indicating a gradual rise in safety‑related interventions after the target year. Technical Service Bulletins (TSBs) show a steady decline from 197 in 2016 to 158 in 2018 and continue falling to 64 by 2024, suggesting that known service issues were progressively addressed. The two 2018 complaints involve “Unknown or Other, Fuel/Propulsion System” and “Service Brakes, Forward Collision Avoidance,” but there were no crash or fire reports, and the data does not specify root causes. **Takeaway:** 2018 exhibits a comparatively clean record with no recalls and low complaint volume, making it one of the stronger years to consider for a used Mirai.
