Filed Mar 5, 2026CA

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.

Service Brakes
Filed Nov 11, 2025CA

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.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
