2004 Toyota Corolla — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 560 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Air bags (restraint system)237 (42.3%)Official recall records for this system: 62, covering model years 1995–2023.
• Speed control & accelerator60 (10.7%)Official recall records for this system: 3, covering model years 1996–2010.
• Visibility (glass, wipers, mirrors)29 (5.2%)Official recall records for this system: 4, covering model years 2003–2014.
• Engine27 (4.8%)Official recall records for this system: 2, covering model years 2005–2008.
• Exhaust & emissions control27 (4.8%)
• Fuel system25 (4.5%)Official recall records for this system: 12, covering model years 2018–2020.

Other / uncategorized: 16 classifications (2.9%) 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 (22,330 records, model years 1995–2026) are most frequently classified under: air bags (restraint system), steering and speed control & accelerator.
• Safety recalls (233 records, model years 1995–2026) are most frequently classified under: air bags (restraint system), lights and equipment & accessories.
• Transport Canada recalls (142 records, model years 1995–2023) are most frequently classified under: air bags (restraint system), electrical system and fuel system.
• Manufacturer communications (6,984 records, model years 1995–2026) are most frequently classified under: equipment & accessories, electrical system and engine.
• Investigations (62 records, model years 1995–2019) are most frequently classified under: air bags (restraint system), engine and lights.

"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

• 247reports included a mileage
• 68,862average 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.

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.

• P0171 in 1 record
• P0420 in 1 record
• P0741 in 1 record

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.
