The Toyota Mirai is a midsized hydrogen fuel cell vehicle or FCV. Originally showcased during the Los Angeles auto show in 2014, the Mirai quickly became one of the fastest-selling FCVs in the market, even into 2022. Nowadays, it’s a good idea to know which are the most reliable Toyota Mirai years if you’re in the market for one of these used cars.
Of course, that can be tricky to answer! Each iteration of the Toyota Mirai has come with different features, inclusions, and potential problems. Let’s take a closer look.
Most Reliable Years for the Toyota Mirai
The Toyota Mirai has been manufactured for several years, and the later years of manufacturing are widely considered to be better (though this is partially because of better hydrogen refueling availability as time has gone on). The most reliable Toyota Mirai years include:
- 2019 Toyota Mirai
- 2020 Toyota Mirai
- 2021 Toyota Mirai
- 2022Toyota Mirai
However, “most reliable” does not always correlate with cost-effectiveness. Even if you find a great used 2021 Toyota Mirai, for example, expect to pay extra both for the initial asking price and for wear and tear costs later on.
THE TOYOTA MIRAI YEARS TO AVOID
The Mirai has been in production since 2016, so used car buyers have plenty of choices. Is the Toyota Mirai reliable? Today, we will talk about the worst Toyota Mirai years to avoid and their reliability issues.
Are Toyota Mirais Generally Reliable?
Whether you choose one of the most reliable Toyota Mirai years or not for your used vehicle, general reliability is something to keep in mind.

According to tiremeetsroad.com, you’ll need to pay for a mandatory ion exchange element and fuel-cell cooling system fluid top-off approximately every 30,000 miles. That costs around $1000. Depending on how often you drive your used Toyota Mirai, this could add up to quite a lot of money indeed.
In addition, edmunds.com indicates that a used Toyota Mirai has an average consumer review score of 3.2 out of 5. Thus, the Toyota Mirai is not nearly as reliable as many other vehicles of the same size and class. This could be due to the increased sophistication and complexity of the hydrogen fuel cell system.

The 2017 Toyota Mirai was rated as one of the worst model years for this hydrogen-powered sedan overall, as was the 2018 Toyota Mirai.
Are Toyota Mirais Expensive to Maintain?
Even a used Toyota Mirai can be expensive, and you’ll also want to keep repair and maintenance costs in mind. Fortunately, a used Toyota Mirai shouldn’t run you too much in terms of annual maintenance fees. According to fiix.io, the annual repair cost for a Toyota Mirai is $237.37. That’s quite affordable, especially when you consider that the average for most vehicles is over $400 per year!
This is partially because repair parts can be acquired at low costs. For example, even a brake pad and rotor replacement appointment will only cost less than $500 on average. But remember the above-mentioned mandatory fluid top-off for the fuel-cell cooling system, which actually makes maintaining a Toyota Mirai more expensive than average.
