GMC Terrain — reported problems
CarFaultIQ holds 28,685 evidence records for the GMC Terrain (2010–2026), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 8,756 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

- Fuel system554 (6.3%)Official recall records for this system: 5, covering model years 2018–2022.
Other / uncategorized: 612 classifications (7.0%) 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 (6,188 records, model years 2010–2026) are most frequently classified under: engine, visibility (glass, wipers, mirrors) and powertrain (transmission & drivetrain).
- Manufacturer communications (22,363 records, model years 2010–2026) 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
- 3,474reports included a mileage
- 72,634average 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.
