2016 Ford C-MAX 1.5L Diesel · AX16 KKA

Recurring corrosion on the coil springs represents the primary mechanical concern for this vehicle, with advisories appearing in both 2025 and 2026. The most recent test on 07 April 2026 resulted in a pass, but it flagged corrosion on both the nearside and offside front coil springs. This follows a 2025 advisory regarding corrosion on the offside front and offside rear coil springs, indicating a progressive pattern of surface degradation across multiple suspension components. While the vehicle has maintained a consistent pass record since 2019, the emergence of these specific advisories suggests that the structural integrity of the spring components is beginning to decline. The vehicle has covered 94,036 miles over its ten-year lifespan, averaging approximately 9,404 miles per year. This usage pattern is consistent with typical UK annual mileage for a vehicle of this age. From a mechanical perspective, this steady accumulation suggests that components such as the suspension bushings, brake discs, and drivetrain elements have been subjected to regular, predictable wear rather than the extreme stress of high-mileage commercial use or the potential degradation associated with long periods of inactivity. There are no significant gaps in the testing history, although the transition from the 2020 test to the 2022 test shows a period where the vehicle was not recorded, which is a minor deviation from the annual testing cycle. A prospective buyer should pay close attention to the suspension system during a test drive to monitor the condition of the flagged coil springs. Listen for any metallic clunking, knocking, or creaking sounds when driving over speed bumps or uneven road surfaces, as these can be symptoms of compromised spring tension or failing spring seats. Additionally, pay attention to the steering feel and ride quality; any sudden pulling to one side or an unsettled, bouncy sensation through the chassis could indicate that the corrosion has progressed beyond surface level and is affecting the spring's ability to dampen road impacts effectively. Beyond the suspension, the absence of defects in the 2022, 2023, and 2024 tests provides a baseline of roadworthiness for other major systems. However, given the recent trend of corrosion advisories, it is prudent to inspect the underside of the vehicle for any signs of significant rust on other suspension linkages, subframe mounting points, or brake pipes. While the current records do not indicate issues with the braking system or exhaust emissions, the presence of corrosion on the coil springs warrants a thorough visual inspection of all exposed metal components to ensure there is no widespread oxidation affecting the vehicle's structural or safety-critical parts.
