2015 Ford Mondeo 2.0L Diesel · CU65 TVW

The 2015 Ford Mondeo presents a pattern of recurring mechanical failures rather than consistent reliability, with multiple MOT tests revealing persistent issues across the rear suspension, braking system, and electrical lighting that recurred at intervals spanning several years. The most recent test on 2026-01-14 resulted in a pass, but the record still carries substantial advisories including a stepped or cracking rear tyre situation, a malfunctioning tyre pressure monitoring system, an excessively worn rear shock absorber bush, non-functional nearside side repeaters, and minor windshield damage. Earlier failures were equally pronounced, such as the 2022-01-13 test where the same nearside side repeater failure coincided with thin rear brake pads, and the 2022-12-16 test where an offside side repeater defect existed alongside brake pad thinning. This cluster of repeated deficiencies suggests systemic rather than isolated problems, and the fact that the vehicle failed again less than nine months after passing in early 2026 indicates the underlying issues were not fully resolved even when older warnings were addressed. The vehicle has accumulated approximately 100,785 miles over its 11-year lifespan, averaging around 9,162 miles per year which aligns with expected usage for its age. However, the testing schedule reveals notable gaps that complicate a complete picture of its condition, particularly the period between the 2024-01-08 pass and the 2026-01-12 failure, which spanned nearly a full calendar year with no intervening MOT. While the average annual mileage is typical, the absence of regular roadworthiness checks during this interval leaves uncertainty about how the vehicle was actually being driven and maintained. High mileage combined with a history of multiple critical failures—especially in the rear suspension and braking systems—implies that certain components experienced accelerated wear or were subjected to conditions beyond their design limits, making the current state of those systems potentially compromised. Focused attention should be directed at the rear shock absorber bush, which was reported as excessively worn in the 2026-01-12 failure, and the stepped or cracked rear tyres noted across multiple tests, which would manifest as uneven handling, increased vibration, or premature tyre deterioration. The nearside side repeaters failing repeatedly throughout the record signals a potential electrical or wiring issue in the interior lighting circuit that requires inspection for corroded connectors or degraded bulbs. Additionally, the rear brake pads appearing thin in two separate tests (2022-01-13 and 2026-01-14) point to progressive brake wear that could compromise stopping performance if not addressed promptly. During a test drive, listen for any knocking or clunking over bumps which may indicate bushing degradation, monitor brake pedal firmness for any judder or sponginess, and visually confirm that all side repeaters illuminate correctly and that the windshield remains free of cracks or excessive damage. Given the documented failures centering on the rear suspension, braking, and lighting systems, a thorough pre-purchase inspection is strongly advised before committing to this vehicle. A mechanic should specifically examine the condition of the rear shock absorber bush for internal play or leakage, perform a thorough check of the tyre tread depth and sidewall integrity on all four wheels, and verify that the braking system is fully functional with proper pad thickness and fluid levels. The advisory regarding the offside bonnet primary retaining device warrants additional scrutiny to ensure the body structure remains intact, while the repeated nearside side repeater failures suggest the interior electrical harness may require replacement. Although the most recent MOT on 2026-01-14 showed a pass, the presence of multiple outstanding advisories across different test cycles means the vehicle's roadworthiness is currently compromised by unresolved components that could fail again under normal driving conditions.
