2019 GMC Truck Terrain

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 Terrain.

Body SUV

The 2019 GMC Terrain is a compact SUV built on General Motors' contemporary global crossover platform, powered by a turbocharged four-cylinder engine that requires 4.2 quarts of 0W-20 motor oil for service fills, and it entered production amid a model generation that has accumulated three formal recalls and 177 total owner complaints to date, with service brakes representing the most frequently cited concern; sitting within a complaint trajectory that dropped dramatically from a peak of 397 issues in 2011 down to just 12 by 2025, the 2019 model reflects a vehicle lineage that had substantially refined its reliability profile over nearly a decade of iterative development.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 60,000 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 2019 GMC Truck Terrain top in one area — the service brakes, 20 of 177 reports (11%), well ahead of the next concern. That matters, because the service brakes are also the target of recall 18V-576 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 7 of the reports describe a crash and 3 a fire — a small share of the total, but worth weighing against the service brakes 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.
