2013 GMC Truck Terrain

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2013 Terrain.

Body SUV

The 2013 GMC Truck Terrain is an SUV whose 5.0-quart, 5W-30 engine oil requirement directly parallels its primary pain point, with the engine serving as the top complaint area among 368 total owner complaints and three recalls. This volume of grievances places the 2013 model just below the generation's 2011 peak of 397 complaints across the 2010-2026 timeline, yet far above the 2025 low of just 12 complaints. Consequently, the 2013 Terrain occupies a distinctly problematic tier within the model's reliability history, meaning researchers can expect a notably higher incidence of engine-related issues compared to the platform's most dependable years.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 97,500 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2013 GMC Truck Terrain dominate in one area — the engine, 136 of 368 reports (37%), well ahead of the next concern. None of this vehicle's 3 recall campaigns target the engine, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 14 of the reports describe a crash and 2 a fire — a small share of the total, but worth weighing against the engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
