4.0L V8 Bi-Turbo
Petrol
Check the transmission software behavior during low-speed shifts, as the 9G-TRONIC can occasionally exhibit harsh engagement that may warrant a software update check.
Inspect the sunroof and door seals for any signs of moisture, as these iconic boxy shapes occasionally experience seal degradation which could affect cabin climate.
Listen for any distinct clicking or ticking from the front suspension when steering at low speeds, as the heavy-duty components can develop minor bushing play over time.
Verify all digital infotainment functions, specifically the dual-screen interface, to ensure no flickering or intermittent connectivity, as complex electrical systems benefit from a comprehensive diagnostic scan.
Recommended major service focusing on drivetrain fluids and spark plug inspection.
Typically the interval for more intensive chassis component checks and full transmission fluid service.
Standard time to assess cooling system hoses and secondary ignition components to maintain the V8's peak performance.
Perform engine oil and filter changes every 10,000km or annually, whichever comes first, to protect the bi-turbo setup.
Monitor brake pad and rotor thickness closely, as the vehicle's weight and power place significant demand on the braking system.
Regularly inspect the air suspension bags for any debris or signs of wear to ensure ride quality remains optimal.
Keep up with Mercedes-Benz software updates to ensure the engine management and infotainment systems operate with the latest efficiency parameters.
Maintain a strict schedule for differential fluid changes to ensure the 4MATIC system remains quiet and responsive.
Estimated repair costs if issues arise
Due to the vehicle's significant curb weight, plan for premium rotor and pad replacements slightly more frequently than standard passenger vehicles.
While robust, if a component in the air suspension system requires attention after the warranty period, it is wise to set aside funds for professional-grade replacement units.
The high-performance nature of the V8 G-Class means high-quality tyres are essential, and they generally require replacement every 20,000km to 30,000km depending on driving style.
