MERCEDES S-Class2009 · 3.0L DIESEL

The vehicle presents a stable roadworthiness profile, though the data indicates a transition toward mechanical wear in later years. While the most recent recorded test in March 2020 at 186,006 miles passed, it introduced advisories for play in both the nearside and offside front wheel bearings. This marks a shift from the clean records of 2018 and 2019, suggesting that front-end components are reaching the end of their operational service life. At 186,006 miles over 17 years, the car averages approximately 11,000 miles per annum, which aligns with typical usage patterns for a luxury executive saloon. The history shows consistent use between 2017 and 2020, with mileage increments of roughly 8,000 miles between each annual test. However, there is a significant gap in data following the March 2020 test. Given the current date in June 2026, the vehicle is long overdue and the current state of the mechanical components remains unknown without a fresh physical inspection. A buyer must prioritize a thorough inspection of the front suspension and drivetrain assembly. The failure in March 2017 regarding a worn ball joint on the nearside front lower suspension arm indicates that the steering components are prone to significant stress. Combined with the 2020 advisories for wheel bearing play, the front end geometry likely requires immediate attention. Attention should also be paid to structural corrosion on the subframes and the condition of the rubber bushings, as high-mileage S-Class vehicles often suffer from degradation in these areas after two decades.
