2016 MERCEDES-BENZ GLS5.5L PETROL

The vehicle currently holds a valid MOT, but the recent history indicates a concerning decline in maintenance standards. While it passed its most recent test on 10 December 2025 at 106,869 miles, it failed that same day due to multiple critical defects. The presence of an inoperative engine malfunction indicator light and a leaking offside front brake pipe suggests that significant mechanical and safety issues were overlooked until the test interval. This represents a shift from the stable condition of previous years to a period of reactive maintenance. The mileage pattern is consistent with a typical high-use luxury vehicle, averaging approximately 10,700 miles per year. The record shows steady progression from 86,419 miles in November 2022 to 106,869 miles in December 2025. There is a clean period between 2023 and 2024 where the vehicle operated without any recorded defects. However, the sudden appearance of the late 2025 failure indicates that despite the consistent mileage, the mechanical upkeep of the braking and electronic systems was neglected prior to the test date. A buyer must conduct a thorough physical inspection of the offside front braking system to ensure the leaking pipe has been replaced and not merely patched. The previous report of brake fluid being significantly below the minimum mark suggests a persistent leak elsewhere in the hydraulic circuit that requires investigation. Furthermore, the engine malfunction light necessitates a diagnostic scan to confirm there is no underlying sensor fault or sensor failure. Finally, the wear on the lower anti-roll bar linkages on both front sides indicates that the suspension components are beginning the end of their service life and should be monitored for further movement or bushing degradation.
