2020 Mercedes-Benz GLE 1.9L Diesel · ND20 FWF

This modern executive SUV displays a mixed testing history defined by a serious safety failure involving severely worn rubber alongside subsequent clean certificates of roadworthiness, culminating in a straight pass recorded on the fourteenth of May 2026. While the vehicle successfully cleared its first three annual inspections either without fault or with minor front edge wear notices, the trajectory hit a notable obstacle during its fifth-year test in July 2025. On that occasion, the car failed the statutory examination when both rear tyres were found to have tread depths falling below the statutory minimum of 1.6 millimetres, resulting in a dangerous defect classification that required immediate rectification before a passing certificate could be issued later that same day. Accumulating 63,101 miles over its six-year lifespan translates to an average of roughly 10,500 miles annually, representing entirely typical, steady usage for a large diesel-powered luxury vehicle of this class. This consistent mileage accrual pattern indicates that the vehicle has been in regular service without extended periods of inactivity or severe over-utilisation, meaning major mechanical assemblies have experienced standard operational cycles rather than the accelerated wear typical of heavy commercial use or the potential component binding sometimes associated with prolonged stationary lay-ups. Given the specific history of premature tyre wear flagged across both axles in previous years, a physical inspection of the current rubber on all four corners is paramount. Prospective buyers should check the inner and outer shoulders of the tyres for edge wear, which can point toward incorrect wheel alignment, suspension geometry misalignment, or excessive loads placed on the heavy chassis. During the static inspection and subsequent test drive, pay close attention to the multi-link air suspension and steering components by listening intently for any knocking, clunking, or excessive body roll when navigating potholes, speed humps, and sharp turns. Furthermore, the mechanical evaluation must account for the substantial weight and complex braking systems inherent to this model platform. While no specific brake or suspension defects have been formally logged on the test certificates apart from the aforementioned tyre issues, the high-performance braking components and heavy wishbone bushings endure significant mechanical stress. During the road test, test the brakes firmly from various speeds to ensure there is no steering pull, brake fade, or undesirable pedal judder, and confirm that the transmission shifts smoothly through all gears without hesitation under load.
