2009 Hyundai Sonata — reported problems

CarFaultIQ holds 528 evidence records for the 2009 Hyundai Sonata, drawn from official sources and owner complaints.

What owners report: issue areas

Owner complaints are classified by the system they concern: 612 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

  • Brakes100 (16.3%)Official recall records for this system: 12, covering model years 2002–2016.
  • Electrical system62 (10.1%)Official recall records for this system: 13, covering model years 1999–2026.

  • Powertrain (transmission & drivetrain)41 (6.7%)Official recall records for this system: 9, covering model years 2011–2023.
  • Body & structure41 (6.7%)Official recall records for this system: 8, covering model years 1997–2021.

Other / uncategorized: 48 classifications (7.8%) 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 (31,856 records, model years 1995–2026) are most frequently classified under: engine, steering and air bags (restraint system).
  • Safety recalls (196 records, model years 1995–2026) are most frequently classified under: air bags (restraint system), lights and fuel system.
  • Transport Canada recalls (215 records, model years 1996–2026) are most frequently classified under: engine, body & structure and brakes.
  • Manufacturer communications (4,129 records, model years 1995–2026) are most frequently classified under: electrical system, engine and equipment & accessories.
  • Investigations (103 records, model years 1999–2021) are most frequently classified under: engine, lights and electrical system.

"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

  • 379reports included a mileage
  • 77,774average 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.
