2016 Mercedes-Benz C 2.0L Hybrid electric (clean) · LP65 KSE

The latest MOT test on the 2016 Mercedes-Benz C recorded a passing outcome on 2025-12-09, though it did not entirely dispel concerns from previous tests. While the vehicle has passed most recent inspections, the history reveals a pattern of recurring advisories and a single major failure, particularly concerning the suspension ball joints and tyre condition. The nearside and offside front lower suspension arm ball joints were flagged as excessively worn in 2021, leading to a major failure, and the nearside upper suspension arm ball joint exhibited slight play in 2024 and 2025. These defects suggest a consistent issue with suspension component wear, which, if left unaddressed, could escalate into structural instability or alignment problems, potentially compromising ride quality and handling over time. The rear tyres also demonstrated severe wear, including exposed ply in 2021 and 2024, indicating either underinflation, excessive load, or improper alignment contributing to uneven tread degradation. The vehicle’s recorded mileage of 189,155 miles at the time of assessment represents a high annual usage rate of approximately 18,916 miles per year, which is notably elevated for a ten-year-old car. Such mileage accumulation over a decade typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as internal engine and transmission elements. The rapid mileage suggests either heavy daily use or periods of prolonged driving, which can exacerbate friction-induced wear on ball joints, bushings, and brake systems. Additionally, the absence of significant mileage gaps between tests—particularly the lack of a standstill period—may have contributed to fluid degradation, such as in the brake fluid, transmission fluid, or coolant, which can harden or become contaminated over time, leading to reduced effectiveness and potential failure points. For a prospective buyer, the most critical areas to inspect are the suspension and braking systems, given the recurring advisories and failure history. On a test drive, listen for unusual clunking or rattling noises from the front suspension, especially when driving over bumps or at low speeds, as these could indicate worn ball joints or bushings. Check for uneven tyre wear patterns, particularly on the edges of the rear tyres, which may suggest misalignment or camber issues. Inspect the brake system for any signs of pulsation or shuddering during braking, which could indicate warped discs or binding calipers, and verify that the brake fluid level is adequate and free of contamination. The rear tyres, in particular, should be closely examined for remaining tread depth and signs of dry rot or cracking, as the exposed ply in previous tests highlights the risk of sudden blowouts or reduced traction. Beyond the mechanical checks, examine the vehicle’s overall condition for signs of prolonged standing, such as corrosion on the undercarriage, particularly around the wheel arches, exhaust system, and suspension mounts. Given the high mileage, the engine oil and transmission fluid should be checked for colour and consistency, with a recommendation to have them serviced or replaced if they appear dark, gritty, or degraded. Inspect the tyre sidewalls for signs of cracking or perishing, which can weaken the tyre structure and lead to sudden failure, especially in older vehicles. Additionally, verify that the service book is up to date, as the last recorded service may not reflect the vehicle’s actual maintenance history. Finally, consider a professional pre-purchase inspection to confirm the condition of the suspension components, brake systems, and drivetrain, as the recurring issues suggest a need for proactive replacement of worn parts to prevent future failures.
