2018 Toyota Mirai

Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

Fuel system
Filed Mar 5, 2026

I own a 2018 Toyota Mirai in California financed through Toyota Financial. The vehicle relies on hydrogen fuel, but hydrogen stations in California are frequently unavailable or offline. Many stations are closed or out of fuel for extended periods. In addition, the price of hydrogen fuel has increased dramatically (approximately three times higher than when the vehicle was purchased). Because of these issues the vehicle often becomes unusable despite still requiring monthly loan payments. Toyota marketed the vehicle as practical to operate in California, but in reality the hydrogen infrastructure is unreliable and frequently unavailable, making the vehicle difficult or impossible to use. This situation creates a safety concern because drivers may be unable to refuel when needed.

On several occasions the Toyota Mirai would slam on the brakes on its own while at a considerable speed with no other cars around. It was very scary and concerning traveling at high speeds and the brakes being applied abruptly automatically.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
