2010 Mercedes-Benz CLS 3.0L Diesel · MW10 BXM

The vehicle presents a concerning maintenance profile characterized by a recurring pattern of reactive repairs rather than preventative care. While it passed its most recent test in March 2026 at 133,291 miles, the failure just one month prior at 132,734 miles reveals a significant decline in mechanical oversight. The trend is worsening, as critical faults in the suspension, wheel bearings, and braking system are appearing annually, suggesting that components are only addressed once they reach the point of legal unroadworthiness. At 133,291 miles over 16 years, the car averages approximately 8,300 miles per year, which is consistent with typical usage for a vehicle of this age. However, the mileage accumulation between February 2024 and February 2025 shows a jump of 14,600 miles in a single year, placing high stress on aging components. This burst of use coincides with the discovery of a fractured wheel and a broken coil spring in early 2025, indicating that the vehicle is being driven to its limits without immediate attention to emerging mechanical failures. A buyer must conduct a thorough physical inspection of the front axle and braking system. The record shows a persistent issue with front wheel bearings exhibiting excessive play across 2025 and 2026, which implies potential hub or bearing failure. Furthermore, the excessive corrosion on the rear brake pipes has been flagged in every test since 2024, indicating a structural degradation of the braking lines that could lead to fluid loss if not replaced. The suspension requires close scrutiny due to the missing differential stabilizer bushes and worn ball joint dust covers that appeared in the February 2026 failure. The frequent reports of tyres worn bald on the inner edges suggest a chronic alignment issue or worn suspension bushings that remain unaddressed. Given the history of oil leaks noted in 2025, a visual check of the engine bay is also necessary to ensure the leak has not worsened or affected rubber components.
