One problem related to engine burning oil has been reported for the 2016 GMC Terrain. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 GMC Terrain based on all problems reported for the 2016 Terrain.
Vehicle since purchase shows no signs of leak but goes through oil at about 1 quart every 1000 miles max. Check engine light always on, sensors indicate possible faulty piston rings. All were problems in later model GMC Terrains. When low on oil while driving and stationary all lights will light up and engine will go into reduced power mode saying to service stabilitrack. Car will not go above 10 mph when in this mode, sometimes unable to move at all. Goes away after more oil added. GMC Terrain had recalls on years 2010-2013 for all engine failure problems/repairs due to faulty piston rings/oil consumption issues. Numerous 2014-2016 GMC Terrains have claims of the reduced power/stabilitrack problem with no solution, I believe both problems are directly related.
