2021 Toyota Mirai: what breaks, and at what mileage

What breaks on the 2021 Toyota Mirai

Only 1 defect report has been filed with NHTSA about the 2021 Toyota Mirai, which is too few to compute mileage percentiles or a risk score. The report reported fuel pump failure.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.

Recalls on the 2021 model year

NHTSA has issued 1 recall campaign covering the 2021 Toyota Mirai, affecting an estimated 19,917 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.

The campaigns cover electronic stability control (esc):control module:software. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.

One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.

ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE

458,110 vehicles 2022-04-13
Defect
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."
Consequence
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.

Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.

Every year of the Toyota Mirai

Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.

Risk score by model year, out of 100

Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.

What the reports on file say

The complaints recorded against the 2021 Toyota Mirai are fuel pump failure (1 report). With a sample this size these are anecdotes rather than a pattern, and they are shown because somebody looking at this exact car would rather see them than nothing.

Why this page is short

A model year needs about 8 reports before percentiles mean anything, and this one does not have them. Complaint volume tracks how many cars were sold and how long they have been on the road, so a thin page usually means a rare car, a new car, or a car whose owners do not file.

Other years of the same model do have enough: 2022. The mechanical parts are often shared across those years, so their pages are the better guide to what this one is likely to do, with the caveat that a shared part is not a shared production line.

Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
