2.0L M254 E20 I4 - GLE 350 4MATIC (Mild Hybrid)
Hybrid
Test drive task: Pay close attention to the 9G-TRONIC transmission during low-speed crawling. | Advice: In some examples, software calibration can cause minor hesitation; ensure the gear changes feel seamless during stop-start traffic to rule out any underlying Mechatronic concerns.
Check this by: Cycling through the MBUX infotainment settings while idling. | Advice: The dual-screen setup is highly sophisticated; ensure there is no screen flickering or system lag, as the electronics rely heavily on the 48V mild-hybrid battery health.
While driving: Listen for any excessive wind noise around the B-pillars. | Advice: On certain V167 models, the window seal fitment can occasionally settle over time; it is worth checking for any high-pitched whistles at motorway speeds.
Test drive task: Perform a tight lock-to-lock maneuver in a parking lot. | Advice: Listen for any clicking or binding from the front suspension components; while generally robust, it is good practice to ensure the steering rack remains quiet and responsive.
Consider a proactive transmission fluid service and inspection of the auxiliary drive belt.
A key service interval where spark plugs, air filters, and a comprehensive check of the 48V hybrid system health should be prioritised.
In many vehicles of this specification, this is a common time to assess the condition of suspension bushings and engine mounts for optimal ride quality.
Verify the service history specifically for the Mercedes-Benz approved engine oil (229.71 spec) which is vital for the M254 engine.
Confirm that the 48V battery system has been inspected during the most recent scheduled service.
Check the tire wear patterns; due to the weight of the vehicle, mismatched or uneven wear can indicate the need for a wheel alignment.
Ensure the panoramic sunroof mechanism has been lubricated regularly to prevent debris buildup in the rails.
Double-check that all software recalls or updates provided by the manufacturer have been completed at an authorised service centre.
Estimated repair costs if issues arise
If the vehicle is equipped with Airmatic, the air struts or compressor may eventually require maintenance as the kilometers climb. Depending on the car's history, you might eventually need to budget for a refresh to maintain that signature luxury ride quality.
While the battery is designed for longevity, if this component needs attention in the future, the estimated cost in NZ is substantial. It is wise to keep a buffer in your long-term vehicle fund for high-tech electrical support.
Given the GLE's size and performance, the braking system works hard. You might eventually need to budget for a complete set of rotors and pads; choosing quality OEM parts ensures the safety systems work in perfect harmony.
