The Mercedes-Benz GLC, produced from 2016 to 2019, represents Mercedes' entry into the competitive compact luxury SUV market. Combining the elegance and technology of a C-Class with the practicality of an SUV, the GLC became a popular choice for Kiwi families seeking a premium driving experience. This guide offers a New Zealand perspective on owning and maintaining a GLC from this era, covering common issues, WOF considerations, and essential maintenance requirements.
Several common problems can affect the 2016-2019 Mercedes-Benz GLC: 1. Timing Chain Issues (M274 Engine): Some petrol models with the M274 engine may experience premature timing chain wear, leading to engine noise and potential failure. Regular oil changes with the correct specification oil are crucial. 2. Turbocharger Problems: Diesel models, in particular, can suffer from turbocharger failures due to oil sludge buildup and wear. Listen for unusual noises or a loss of power. 3. Air Suspension Problems: Models equipped with air suspension can experience leaks and compressor failures. Replacing these components can be costly. 4. Electrical Issues: Like many modern Mercedes-Benz vehicles, the GLC can be prone to electrical issues, including problems with the infotainment system, sensors, and control modules. Diagnostic scans are essential for accurate troubleshooting.
When taking your GLC for a WOF inspection in New Zealand, be aware of these potential failure points: 1. Tyres: Ensure tyres meet legal tread depth requirements and are free from damage. Uneven wear can indicate suspension or alignment issues. 2. Brakes: Check brake pads, rotors, and brake lines for wear and leaks. The electronic parking brake should function correctly. 3. Lights: All lights, including headlights, taillights, brake lights, and indicators, must be in working order. Pay attention to LED lighting, as individual LEDs can fail. 4. Suspension Components: Inspect suspension components, including struts, shocks, and ball joints, for wear, damage, and leaks. Air suspension systems should raise and lower the vehicle evenly and maintain the correct ride height. 5. Fluid Leaks: Check for oil and coolant leaks from the engine, transmission, and cooling system. Leaks can lead to WOF failure and potential mechanical problems.
The GLC offers a range of engines, including petrol, diesel, and even hybrid options. The '250' and '300' petrol models are popular choices, providing a good balance of performance and efficiency. Diesel models, like the '220d' and '250d', offer superior fuel economy, ideal for longer commutes and road trips. The interior is well-appointed, featuring premium materials and advanced technology, including the COMAND infotainment system. Ride comfort is generally excellent, and the GLC handles well in various driving conditions. Keep an eye out for models with the optional air suspension, which provides an even smoother ride.
