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.

What 2018 Toyota Mirai owners say
Most recent owner complaints, unedited.
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.
