Common issues on the GLS include air suspension problems (compressor failure, leaks), MBUX software glitches (screen freezing, connectivity issues), and potential oil leaks from the engine. Some owners have reported issues with the driver assist functions, such as adaptive cruise control and lane keeping assist.

WOF tips
During a WOF inspection, pay close attention to the air suspension system. Ensure it's functioning correctly and that there are no visible leaks or sagging. Tyre condition is crucial, especially given the size and weight of the GLS. All lights, including the complex LED systems if fitted, must be operational. Check for any fluid leaks, especially oil and coolant. Brake pads/rotors on a larger vehicle also take more punishment and potentially require more frequent replacement.
