Infiniti QX50 — reported problems
CarFaultIQ holds 1,855 evidence records for the Infiniti QX50 (2014–2025), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 800 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Engine284 (35.5%)Official recall records for this system: 2, covering model years 2019–2022.
- Driver-assistance systems100 (12.5%)Official recall records for this system: 1, covering model years 2019.
- Electrical system86 (10.8%)
- Powertrain (transmission & drivetrain)62 (7.8%)
- Brakes44 (5.5%)
- Fuel system36 (4.5%)
Other / uncategorized: 76 classifications (9.5%) 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 (544 records, model years 2014–2025) are most frequently classified under: engine, driver-assistance systems and electrical system.
- Manufacturer communications (1,268 records, model years 2014–2025) 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
- 198reports included a mileage
- 46,025average 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.

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.
