2018 Toyota Mirai — reported problems and evidence

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

Owner complaints (60 records, model years 2016–2023) are most frequently classified under: driver-assistance systems, fuel system and speed control & accelerator.
Manufacturer communications (1,727 records, model years 2016–2026) are most frequently classified under: equipment & accessories, electrical system and body & structure.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
