How GMC schedules service: Oil Life System
GMC trucks and SUVs use the GM Oil Life System (OLS) — the same algorithm as Chevrolet. Because GMC's lineup is exclusively trucks and SUVs, severe-service intervals apply to most owners (towing, hauling, off-roading). The schedule below surfaces the items most relevant to GMC's truck-focused buyer.

AIR BAGS:SIDE/WINDOW
Campaign #15V666000 · 16/10/2015
Issue: General Motors LLC (GM) is recalling certain model year 2015 Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain vehicles. The affected vehicles have front seat-mounted side impact air bags whose inflator may rupture upon its deployment.
Risk: In the event of a crash necessitating deployment of one or both of the side impact air bags, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. Additionally, if the air bag does not properly inflate, the driver or passenger is at an increased risk of injury.
Fix: GM will notify owners, and dealers will replace the side impact air bag modules, free of charge. The recall began on October 19, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782. GM's number for this recall is 01320.

EXTERIOR LIGHTING:HEADLIGHTS
Campaign #22V137000 · 08/03/2022
Issue: General Motors, LLC (GM) is recalling certain 2010-2017 GMC Terrain vehicles. A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
Fix: Dealers will install headlamp appliques, free of charge. Owner notification letters were mailed September 8, 2022. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is N222363740.

Issue: General Motors, LLC (GM) is recalling certain 2014-2015 Chevrolet Equinox and GMC Terrain vehicles. The ball joints in the windshield wiper module may corrode, causing one or both windshield wipers to fail.
Risk: Inoperative windshield wipers can reduce visibility in certain driving conditions, increasing the risk of a crash.
Fix: Dealers will inspect the wiper module, and repair or replace it as necessary, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on April 21, 2022. Owner notification letters were mailed on October 25, 2022. Owners may contact Chevrolet customer service at 1-800-222-1020 and GMC customer service at 1-800-462-8782. GM's number for this recall is N212352530.

~$200–$275
DIY
~$25–$100

Dex-Cool Engine Coolant
Every 50,000 miDex-Cool (orange): first change at 150,000 miles or 5 years, then every 50,000. Duramax diesel uses ELC (red) — different chemistry, do not mix.
