The GLC 300 4MATIC returns 23 mpg city and 31 mpg highway on the EPA cycle. Premium unleaded is required. Real-world figures sit close to the official numbers on mixed routes.
Mercedes uses the ASSYST Plus system. The first Service A arrives near 10,000 miles or one year and covers oil, filter and multi-point checks. Later services alternate between A and B roughly every 10,000–20,000 miles.
Euro NCAP gave the generation five stars in 2022. Adult occupant protection scored 92 percent and child protection 90 percent. Standard kit includes Active Brake Assist with pedestrian detection, Blind Spot Assist, PRE-SAFE, lane-keeping support and a full set of airbags.
The car is covered by a four-year / 50,000-mile limited warranty that includes powertrain. Roadside assistance matches that term. Keeping to the ASSYST schedule and using approved fluids helps maintain long-term reliability.
