The Mercedes-Benz GL-Class (X166) from 2012 to 2015 offers a blend of luxury SUV comfort and surprising utility. Built to tackle diverse driving conditions, it found a niche amongst discerning Kiwi buyers. From family adventures to navigating urban landscapes, the GL-Class aimed to provide a premium experience. However, as these vehicles age within the New Zealand fleet, it's vital to be aware of potential maintenance needs and common problem areas, viewed through the lens of our unique WOF requirements and driving environment.
Common issues to watch out for in the GL-Class include air suspension problems (leaks, compressor failure), oil leaks (especially around the valve cover gaskets and oil cooler), wear in the timing chain system (particularly on higher mileage vehicles), and issues with the electronic control units (ECUs). Diesel models can be prone to diesel particulate filter (DPF) clogging, especially if used primarily for short trips. Check for coolant leaks, as these can lead to overheating. Also, the electronic parking brake can sometimes experience failures.
WOF tips
When taking your GL-Class for a WOF inspection, pay close attention to the suspension system. Air suspension leaks will result in a failure. Check that all lights, including the often complex headlight systems, are functioning correctly. Tyres must meet the minimum tread depth requirements and be of the correct size and load rating. The braking system, including brake pads and rotors, will be thoroughly inspected. Ensure the parking brake functions correctly. As with any vehicle, check for rust, especially around the undercarriage and suspension components. Steering components will be carefully checked, given the size and weight of the vehicle.
