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.

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.

Filed Mar 7, 2024

In 2021 I found a Toyota Mirai Hydrogen Fuel lease take over opportunity on [XXX] I saw the car in person and applied to take over the lease from Toyota Financial. A month and a half later I was able to take possession of the car. I thought I am going to get the $17,000 fuel card with the car that Toyota blocked. This was a used car that I got with over 4,000 miles on the car. Toyota financial Never told me that I cannot use the fuel card, when I applied to get the car? Issues with the car: Not finding Fuel, I live in West Los Angeles/BH There were Hydrogen Fuel station in Van Nuys, Studio City, Topanga, East Hollywood, Santa Monica, all very far from me, the west Hollywood Hydrogen fuel station which was closer has been under construction. Each Gas Station that offers Hydrogen fuel, usually has only "One" Hydrogen Fuel Pump, that none of them is serviced by the gas station, they all have a separate owners which are renting space from the gas station, which huge lines of cars waiting and praying so they can get Hydrogen fuel. There has been many times that I had to drive from one Hydrogen Station to another, to get fuel, and been unsuccessful in getting Hydrogen for my Mirai. There was once that I ran out of fuel while trying to find Hydrogen Fuel. So I had to tow the Mirai to a gas station in Thousand Oaks to get fuel. I constantly have problems with the car. There have has been many times that Hydrogen was not available, the pump did not work, it did not accept payment, it only gave a few dollars of fuel at a time, the pump did not disengage from the car (there has been times that the pump did not seperate from my gas tank for half an hour, I have it on film) Every Mirai owner I have met at different gas stations are sick and tired of dealing with all the fuel issues associated with the Mirai. Before I took over the Mirai lease, I went to the Santa Monica Toyota dealer, they told me that every Mirai comes with a $17,000 fuel card!
