Toyota Mirai — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 104 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Driver-assistance systems32 (30.8%)Official recall records for this system: 2, covering model years 2023–2025.
• Fuel system20 (19.2%)
• Speed control & accelerator12 (11.5%)
• Electrical system8 (7.7%)Official recall records for this system: 1, covering model years 2024.
• Brakes6 (5.8%)
• Engine6 (5.8%)

Other / uncategorized: 6 classifications (5.8%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

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
