2002 Infiniti QX4 — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 54 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Suspension14 (25.9%)Official recall records for this system: 1, covering model years 1997–2003.
• Steering7 (13.0%)Official recall records for this system: 2, covering model years 1997–2003.
• Air bags (restraint system)5 (9.3%)Official recall records for this system: 11, covering model years 2002–2003.
• Speed control & accelerator4 (7.4%)
• Brakes3 (5.6%)
• Engine3 (5.6%)

Other / uncategorized: 2 classifications (3.7%) 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

• 25reports included a mileage
• 112,373average 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.
