Infiniti Q45 — reported problems

CarFaultIQ holds 1,219 evidence records for the Infiniti Q45 (1995–2006), drawn from official sources and owner complaints.

What owners report: issue areas

Owner complaints are classified by the system they concern: 278 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

  • Tires & wheels38 (13.7%)Official recall records for this system: 2, covering model years 2000–2001.
  • Electrical system36 (12.9%)Official recall records for this system: 3, covering model years 1997–1998.
  • Engine30 (10.8%)Official recall records for this system: 3, covering model years 2001–2002.
  • Air bags (restraint system)28 (10.1%)Official recall records for this system: 2, covering model years 2003–2005.
  • Speed control & accelerator28 (10.1%)
  • Suspension20 (7.2%)

Other / uncategorized: 4 classifications (1.4%) 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 (212 records, model years 1995–2005) are most frequently classified under: tires & wheels, electrical system and engine.
  • Manufacturer communications (952 records, model years 1995–2006) 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

  • 118reports included a mileage
  • 80,356average 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.
