2018 Mazda Mazda6 — reported problems

CarFaultIQ holds 610 evidence records for the 2018 Mazda Mazda6, drawn from official sources and owner complaints.

What owners report: issue areas

Owner complaints are classified by the system they concern: 82 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

Other / uncategorized: 10 classifications (12.2%) 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 (4,408 records, model years 2003–2021) are most frequently classified under: air bags (restraint system), body & structure and electrical system.
  • Safety recalls (117 records, model years 2003–2019) are most frequently classified under: air bags (restraint system), fuel system and lights.
  • Transport Canada recalls (85 records, model years 2004–2019) are most frequently classified under: air bags (restraint system), fuel system and body & structure.
  • Manufacturer communications (8,064 records, model years 2003–2021) are most frequently classified under: equipment & accessories, electrical system and engine.
  • Investigations (28 records, model years 2003–2010) are most frequently classified under: air bags (restraint system), fuel system and doors, latches & locks.

"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

Diagnostic codes found in evidence for this vehicle

These codes appear by explicit identifier in official records matched to this exact model and year.

A code appearing in a record means the code was named in that document. It is not a diagnosis of this vehicle, not a fault this vehicle has, and not an indication of urgency. Diagnosis requires reading live data from the vehicle.
