Grade a specific Mercedes-Benz GLC
Reliability changes from year to year. Pick a model year to see its grade, then add mileage and price to get a deal score and estimated miles remaining.
The Mercedes-Benz GLC earns a B overall reliability grade from GradeMyCar, with a C+ for its engine and a B+ for its transmission. It ranks 12th of 17 luxury vehicles we grade. The engine (C+) is the weaker of its two major components, so ask for oil-change records and have a mechanic check for leaks and oil consumption. Grades are based on 697 owner complaints filed with NHTSA for the 2016-2023 model years, adjusted for how many were sold.
