2003 Chevrolet Avalanche — reported problems

CarFaultIQ holds 1,143 evidence records for the 2003 Chevrolet Avalanche, drawn from official sources and owner complaints.

What owners report: issue areas

Owner complaints are classified by the system they concern: 451 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

  • Brakes136 (30.2%)Official recall records for this system: 6, covering model years 2002–2005.
  • Electrical system128 (28.4%)Official recall records for this system: 5, covering model years 2007–2012.

  • Speed control & accelerator22 (4.9%)
  • Powertrain (transmission & drivetrain)18 (4.0%)Official recall records for this system: 2, covering model years 2005–2013.
  • Steering17 (3.8%)Official recall records for this system: 1, covering model years 2013.

Other / uncategorized: 9 classifications (2.0%) 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 (5,718 records, model years 2002–2013) are most frequently classified under: air bags (restraint system), brakes and electrical system.
  • Safety recalls (82 records, model years 2002–2013) are most frequently classified under: air bags (restraint system), brakes and fuel system.
  • Transport Canada recalls (77 records, model years 2002–2013) are most frequently classified under: air bags (restraint system), fuel system and brakes.
  • Manufacturer communications (16,382 records, model years 2002–2013) 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

  • 319reports included a mileage
  • 93,569average 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.
