Spend a few minutes specifically testing the MBUX touchscreen and voice control. Ensure the system responsiveness is smooth, as complex software updates can occasionally be required.
When transitioning between low-speed stop-start traffic, pay attention to the 9G-TRONIC transmission. It is generally very refined, but it is wise to ensure the gear shifts feel fluid and hesitation-free.
Adjust the ride settings through the drive modes. If the vehicle is equipped with air suspension, ensure the car levels out correctly and that you don't hear any unusual hissing sounds during height adjustments.
Check the condition of the alloy wheels and low-profile tires for any evidence of curbing or sidewall bubbles, as the 4MATIC system and larger wheels are sensitive to uneven road surfaces.
Usually time for the first major oil and filter service; ensure service records show genuine Mercedes-Benz parts were used.
The transmission fluid and filter service is typically scheduled around this stage to maintain shift quality.
This is a good point to have a specialist inspect the cooling system hoses and the auxiliary battery for the 48V mild-hybrid system.
Verify that the service history is documented in the Digital Service Booklet (DSB) to ensure the warranty remains valid.
Check that the tire tread is even across all four corners, which indicates the 4MATIC alignment is healthy.
Confirm the 48V mild-hybrid battery health has been checked during the most recent scheduled dealer visit.
Ensure all software updates for the MBUX infotainment system have been performed during previous services.
Inspect the brake pad and rotor thickness, as the performance nature of the GLC Coupe can lead to accelerated wear depending on driving style.
Estimated repair costs if issues arise
While these systems are robust, in the long term, you might eventually need to budget for battery management system recalibration or eventual replacement as the car moves into higher mileage territory.
If the vehicle is specified with Airmatic suspension, it is common to consider that air struts can require maintenance as they age. Setting aside a contingency fund is a smart move for long-term ownership.
Due to the vehicle's weight and performance capabilities, the braking system works quite hard. If this component needs attention in the future, it is best to use OEM parts to maintain the car's stopping dynamics.
