2017 Ford Focus 1.5L Diesel · WM17 DVT

The most recent MOT test on the 2017 Ford Focus recorded a failure on 2026-06-03, with the primary defect being a missing near-side constant velocity (CV) joint boot, which is a critical component for preventing lubricant leakage and ensuring smooth drivetrain operation. This failure follows a pattern of recurring issues related to the near-side CV joint boot, having been noted as severely deteriorated in 2024 and previously failing in 2023. While the vehicle passed in 2025 and 2023, the presence of multiple failures and advisories over the past three years suggests a deteriorating maintenance trend, particularly concerning the drivetrain’s long-term integrity. The emissions advisory in 2024 and the dangerous failure in 2023—where the rear tyre was below the legal minimum tread depth—highlight broader concerns about exhaust system performance and tyre wear management, which could escalate if not addressed promptly. The recorded mileage of 152,649 miles for a vehicle aged nine years represents an exceptionally high annual usage rate of approximately 16,961 miles per year, which is far above the average for its class. Such rapid mileage accumulation accelerates wear on critical components, including the CV joints, suspension, brakes, and drivetrain seals, all of which have been flagged in the MOT history. The absence of significant mileage gaps suggests the vehicle has been in active service, potentially under conditions that exacerbate mechanical stress—such as frequent short trips, aggressive driving, or exposure to harsh environmental factors. This pattern necessitates heightened scrutiny of consumable items like fluids, filters, and wear items, as well as a focus on preventing further drivetrain failures, which could become costly without timely intervention. For the prospective buyer, the most urgent priority is to address the missing CV joint boot and the associated drivetrain concerns. The CV joint boot failure is a major defect that compromises the vehicle’s roadworthiness and could lead to catastrophic drivetrain failure if left unrepaired. On a test drive, listen for unusual noises from the rear axle, particularly a grinding or clunking sound when accelerating or turning, which may indicate a failed CV joint or misaligned driveshaft. Inspect the boot visually for signs of damage or oil leaks around the joint, and check for uneven tyre wear or excessive play in the steering wheel, which could signal drivetrain issues. The near-side headlamp failure from 2024 also warrants immediate replacement, as a non-functional dipped beam is not only a safety hazard but also a legal requirement. Additionally, the rear reflector and registration plate failures from 2023 should be corrected to avoid future MOT failures, as these are straightforward but essential compliance checks. Beyond the immediate defects, the high mileage and recurring advisories necessitate a thorough mechanical inspection to identify wear progression in other critical areas. Focus on the suspension system, particularly the near-side suspension components, as the CV joint failures may correlate with related bush and spring wear. Listen for clunking noises from the suspension during cornering or over bumps, which could indicate worn suspension bushes or damaged coil springs. Check the brake system for signs of uneven wear or binding calipers, especially if the vehicle has been in heavy use, as standing brakes can cause corrosion or binding. Inspect the exhaust system for leaks or discolouration, which may indicate catalytic converter or manifold issues contributing to the 2023 emissions failure. For fluid systems, verify the condition of the engine oil, transmission fluid, and brake fluid, paying particular attention to their age and potential degradation, as fluids can break down over time even without mileage. Finally, conduct a visual inspection of the tyres for sidewall cracking or perishing, which can occur even at moderate mileages due to age-related degradation, and ensure the tread depth meets legal requirements. A comprehensive service history check, if available, would also provide valuable context on past maintenance and potential areas of neglect.
