Infiniti QX4 — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 774 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Suspension176 (22.7%)Official recall records for this system: 1, covering model years 1997–2003.
• Body & structure106 (13.7%)Official recall records for this system: 3, covering model years 1997–2003.
• Steering102 (13.2%)Official recall records for this system: 2, covering model years 1997–2003.
• Fuel system52 (6.7%)Official recall records for this system: 2, covering model years 1997–2001.
• Equipment & accessories48 (6.2%)
• Powertrain (transmission & drivetrain)36 (4.7%)

Other / uncategorized: 26 classifications (3.4%) 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 (550 records, model years 1997–2003) are most frequently classified under: suspension, body & structure and steering.
• Manufacturer communications (737 records, model years 1997–2003) are most frequently classified under: equipment & accessories, electrical system and visibility (glass, wipers, mirrors).

"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

• 326reports included a mileage
• 127,833average 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.

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.
