2013 Ford C-MAX 1.6L Diesel · FN13 USC

The 2013 Ford C-Max’s latest MOT test on 2026-03-16 resulted in a passing outcome, though it carried persistent advisories regarding near-side rear brake discs that remain worn, lightly pitted, and slightly corroded across multiple tests. While the vehicle did not fail in this most recent inspection, the recurring nature of these brake disc advisories—particularly the consistent mention of wear and corrosion—suggests a pattern of gradual but ongoing degradation rather than a sudden deterioration. The fact that the disc condition has not escalated to a dangerous failure category in recent years indicates that the braking system is still functional, though it demands closer attention to prevent further deterioration. The presence of a rear brake fluctuating advisory in earlier tests also hints at potential uneven wear or minor mechanical issues within the rear brake assembly, which should be monitored during a thorough inspection. The vehicle’s recorded mileage of 172,551 miles over approximately 13 years equates to roughly 13,273 miles annually, which is significantly higher than the typical usage rate for a 13-year-old car. Such high mileage, especially without evident long periods of inactivity, suggests substantial and sustained mechanical stress on consumables, suspension components, and drivetrain elements. The rapid accumulation of miles may accelerate wear on brake discs, tyres, and suspension bushes, as well as contribute to fluid degradation in the braking, cooling, and lubrication systems. The absence of service records or mileage gaps could also indicate that the vehicle has been driven under demanding conditions, potentially leading to premature failure of critical components if not addressed proactively. Given the recurring advisories on brake discs and tyres, the prospective buyer should prioritise a detailed inspection of the braking system, focusing on the rear discs and pads for signs of uneven wear, binding, or excessive heat damage. During a test drive, listen for unusual grinding noises from the rear brakes, which could indicate worn pads or warped discs, and check for a firm, even pedal response without excessive sponginess or pulsation. Additionally, inspect the rear brake discs for any signs of excessive corrosion, particularly on the inner surfaces where moisture can pool, and verify that the calipers are not binding or seized. If the rear brake fluctuating advisory persists, this may suggest hydraulic issues or misalignment, warranting further investigation into the brake fluid condition and hydraulic system integrity. For tyres, the buyer should replace all four tyres to meet legal requirements, as the offside front tyre failed due to exposed ply and the near-side rear tyres are worn to dangerous levels. The presence of inner-edge wear and cracking on the near-side rear tyres indicates aggressive cornering or misalignment, which could have contributed to the tyre failure. Inspect the tyres for any signs of sidewall damage, such as cracks or perishing, which can compromise structural integrity, especially on older vehicles. The underbody advisories from previous MOTs—such as obscured underside components—also suggest that the vehicle may have accumulated dirt, debris, or minor corrosion beneath the chassis, particularly around the suspension and exhaust systems. A thorough visual inspection of the undercarriage for leaks, rust, or structural damage is essential, as is checking the fluid levels in the cooling, brake, and power steering systems for any signs of contamination or degradation. Given the vehicle’s age and mileage, a service history check for fluid replacements and component replacements—such as suspension bushes, coil springs, and exhaust components—would be highly recommended to ensure long-term reliability.
