1998 GMC Sonoma — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 202 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Visibility (glass, wipers, mirrors)56 (27.7%)Official recall records for this system: 3, covering model years 1995–1996.
• Seats31 (15.3%)
• Brakes18 (8.9%)Official recall records for this system: 13, covering model years 1995–2000.
• Body & structure15 (7.4%)
• Air bags (restraint system)11 (5.4%)
• Powertrain (transmission & drivetrain)11 (5.4%)Official recall records for this system: 2, covering model years 1996.

Other / uncategorized: 4 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 (2,012 records, model years 1995–2003) are most frequently classified under: brakes, visibility (glass, wipers, mirrors) and body & structure.
• Manufacturer communications (2,655 records, model years 1995–2004) are most frequently classified under: equipment & accessories, engine 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

• 60reports included a mileage
• 72,238average 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.

• P0894 in 2 records
• P0420 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.
