Mazda CX-30 — reported problems
CarFaultIQ holds 3,792 evidence records for the Mazda CX-30 (2020–2026), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 772 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Engine134 (17.4%)
- Driver-assistance systems114 (14.8%)Official recall records for this system: 1, covering model years 2024.
- Electrical system88 (11.4%)
- Brakes68 (8.8%)Official recall records for this system: 4, covering model years 2020–2023.
- Visibility (glass, wipers, mirrors)38 (4.9%)
- Powertrain (transmission & drivetrain)34 (4.4%)
Other / uncategorized: 94 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 (494 records, model years 2020–2026) are most frequently classified under: engine, driver-assistance systems and electrical system.
- Manufacturer communications (3,267 records, model years 2020–2026) are most frequently classified under: electrical system, equipment & accessories 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
- 56reports included a mileage
- 16,303average 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.
Evidence by model year
Records held per model year. Select a year to narrow this page to it.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.

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.
