2.2L e-XDi (133kW) - 4WD
Diesel
While driving at low speeds, pay close attention to the smoothness of gear changes in the E-Tronic transmission; if hesitation occurs, it's common to consider a professional fluid flush or software update to restore refinement.
During your test drive, accelerate firmly on an open road to monitor for any hesitation or warning lights; in diesel SUVs like this, the DPF (Diesel Particulate Filter) system may eventually require a long motorway run or a manual regeneration if used primarily for city commuting.
When navigating over speed bumps or uneven driveways, listen for subtle knocks or squeaks from the front suspension; because this is a heavy 4WD, it's common to consider refreshing the ball joints or bushings to keep the steering feeling sharp.
Check this by cycling through all the touchscreen menus and testing the reverse camera several times; occasionally, infotainment units in these models benefit from a firmware update to ensure the electronic sensors and displays remain responsive.
This is a great time to check the transmission fluid and replace the fuel filter to keep the 2.2L e-XDi engine running efficiently.
At this stage, it's common to consider a comprehensive cooling system flush and a detailed inspection of the drive belts and tensioners.
For long-term reliability, you might eventually need to budget for a professional cleaning of the intake manifold and a check of the fuel injector seals.
Verify the service log for consistent 12-month or 15,000km oil changes using the correct low-ash synthetic oil.
Engage the 4WD high and low ranges to ensure the transfer case switches smoothly and without excessive noise.
Inspect the tow bar area for any heavy wear or wiring corrosion, especially if you plan on utilizing the Rexton's 3.5-tonne towing capacity.
Check the condition of the tyres for even wear patterns, as heavy 4WDs are sensitive to wheel alignment accuracy.
Ensure the battery is in peak health, as the modern electronics and stop-start systems in the G4 Rexton perform best with a strong voltage supply.
Estimated repair costs if issues arise
Depending on the car's towing history, you might eventually need to budget for a specialized transmission service including a new filter and high-quality synthetic fluid to maintain that Mercedes-sourced smoothness.
If this component needs attention in the future due to carbon build-up, a professional chemical clean or 'off-car' bake is a common maintenance task to keep the 133kW engine breathing correctly.
In cars of this weight, it's common to consider high-quality heavy-duty brake components; you might eventually need to budget for both pads and rotors to ensure the best stopping performance in NZ conditions.
