3.0L L6 Mild Hybrid
Hybrid
Test Drive Task: Cycle through all three differential locks while at low speed to ensure smooth engagement and no warning lights appear on the dashboard. | Observation: In the W463A, complex electronic locking systems can sometimes report faults if not exercised regularly.
Test Drive Task: Listen carefully for wind noise around the A-pillars and door seals at highway speeds (approx. 80-100km/h). | Observation: Given the boxy aerodynamics, seals on these units may require adjustment as they age to maintain cabin quietness.
Test Drive Task: Observe the transmission shifting behavior under light acceleration to ensure the 9G-TRONIC gearbox feels fluid without hesitation. | Observation: It is common in sophisticated 9-speed units to monitor software updates, which can often resolve minor gear hunting symptoms.
Test Drive Task: Operate the infotainment screen and touchpad extensively while the vehicle is stationary to check for connectivity drops. | Observation: Complex MBUX systems can occasionally benefit from a firmware refresh if touch responsiveness seems inconsistent.
Consider a major software diagnostic scan and thorough inspection of the suspension bushings.
This is a prudent time to assess the condition of the drivetrain fluids and ensure the Mild Hybrid battery health report is requested.
In cars of this nature, this milestone is often the point to evaluate cooling system components and spark plug longevity.
Verify the presence of a complete Mercedes-Benz dealer service history to ensure the Mild Hybrid system updates are current.
Check the condition of the heavy-duty brake pads and rotors, as these vehicles carry significant mass.
Inspect the underbody for signs of off-road usage, focusing on skid plates and chassis mounting points.
Confirm that the 48V system diagnostics have been performed during the most recent scheduled service.
Test the function of all power-operated features, including seat adjustments and ambient lighting zones.
Estimated repair costs if issues arise
Future Budget Planning: While long-lasting, it is wise to set aside a contingency fund for potential high-voltage system maintenance outside of warranty.
Future Budget Planning: Due to the G-Class weight, brake consumables are used more rapidly than in passenger sedans; budget for premium replacements periodically.
Future Budget Planning: High-performance all-terrain tyres for the large wheel diameters can be a significant recurring cost.
