The Mercedes-Benz GLC, released from 2017 onwards, became a popular choice in New Zealand's luxury SUV market. Blending refined comfort with a dash of off-road capability (depending on the model), the GLC offered a desirable blend of practicality and prestige.
Potential problems include issues with the 9-speed automatic transmission (hesitation or rough shifts), sensor failures impacting driver-assistance systems, and occasional air suspension problems (if equipped). Oil leaks from the engine and drivetrain are also worth keeping an eye on. Inspect panoramic sunroofs for proper operation and signs of water leaks, as these are a known weak point.
WOF tips
Pay close attention to tyre condition (expensive staggered fitments on some models), brake wear (especially rotors), and the proper functioning of all lights, including the often-complex LED lighting systems. Suspension components, particularly the bushings and ball joints, should be inspected for wear during WOF checks. Ensure all safety systems, such as airbags and seatbelts, are functioning correctly.
