2011 Mazda CX-9 — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 209 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Brakes100 (47.8%)
• Powertrain (transmission & drivetrain)26 (12.4%)
• Air bags (restraint system)22 (10.5%)Official recall records for this system: 9, covering model years 2007–2018.
• Engine15 (7.2%)
• Suspension8 (3.8%)Official recall records for this system: 4, covering model years 2007–2016.
• Electrical system5 (2.4%)Official recall records for this system: 2, covering model years 2007–2018.

Other / uncategorized: 5 classifications (2.4%) 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 (2,964 records, model years 2007–2023) are most frequently classified under: brakes, engine and powertrain (transmission & drivetrain).
• Manufacturer communications (6,912 records, model years 2007–2023) are most frequently classified under: equipment & accessories, electrical system and engine.

"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

Mileage reported when the issue occurred

• 137reports included a mileage
• 76,784average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.
