The Mercedes-Benz M-Class ML 500 (W164) from 2005 to 2011 effortlessly blends luxury with off-road prowess. This SUV has won over New Zealand families seeking spaciousness and a smooth ride while offering an adventurous spirit. As these vehicles become more accessible, potential buyers should be mindful of their intricate engineering and the importance of thorough maintenance to avoid costly surprises down the road.
Common problems include air suspension failures (leaks, compressor issues on Airmatic models), oil leaks (engine and transmission), transmission problems, worn suspension components, transfer case issues, and electrical problems. The diesel models can suffer from injector problems and DPF (Diesel Particulate Filter) issues. Rust is also a potential concern.
WOF tips
Pay close attention to suspension components, especially the air suspension (if equipped) for leaks and proper function. Check for oil leaks around the engine and transmission. Ensure all lights and safety systems are working correctly. Inspect the brakes, including the parking brake. Rust is a WOF failure point, particularly around the wheel arches, sills, and underbody. Check for excessive smoke from diesel models.
