GMC Sierra — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 8,814 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

Other / uncategorized: 182 classifications (2.1%) 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 (7,170 records, model years 1995–2017) are most frequently classified under: brakes, visibility (glass, wipers, mirrors) and powertrain (transmission & drivetrain).
• Safety recalls (170 records, model years 1995–2016) are most frequently classified under: powertrain (transmission & drivetrain), electrical system and brakes.
• Transport Canada recalls (375 records, model years 1995–2026) are most frequently classified under: air bags (restraint system), brakes and seat belts.
• Manufacturer communications (8,943 records, model years 1995–2017) are most frequently classified under: equipment & accessories, engine and electrical system.
• Investigations (68 records, model years 1995–2008) are most frequently classified under: brakes, body & structure and doors, latches & locks.

"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

• 3,766reports included a mileage
• 61,307average 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.

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.
