2017 Ford Fiesta 1.5L Diesel · LS67 OCL

The most recent MOT, dated 14 October 2025, resulted in a failure. Although the test recorded a pass for the overall inspection, it listed two major failures on the front service brakes – excessive fluctuation on both the nearside and offside – together with advisories that the front brake discs are worn, pitted and scored. Earlier years show a pattern of recurring front‑disc wear and a single dangerous tyre bulge in 2021, but no major failures until now, indicating that the vehicle’s maintenance condition has begun to deteriorate rather than improve. With 47,076 miles recorded over nine years the Fiesta averages just over 5,200 miles per annum, well below the typical UK usage of around 10‑12 000 miles a year. Such low annual mileage often points to light, possibly intermittent use or long periods of storage. Light use reduces wear on consumables but can promote corrosion of brake components, suspension bushings and electrical connections, and it accelerates the ageing of rubber items such as tyres, seals and hoses. The front brake system requires immediate attention. The repeated advisories about disc wear suggest the rotors are approaching the minimum thickness and the scoring will diminish braking efficiency and increase the risk of vibration. The “excessively fluctuating” service brake fault is commonly caused by uneven disc wear, warped rotors, sticking caliper pistons or a deteriorating master cylinder. On a test drive the buyer should feel for a pulsating pedal, a spongy or soft feel under heavy braking, and listen for squealing or grinding. Replacement of the front discs, a thorough inspection of the calipers (including piston movement and seal condition), and a check of the brake fluid for moisture are advisable before committing to purchase. The rear child‑seat advisory does not affect the vehicle’s roadworthiness but the adult seatbelt should be inspected for proper operation once the child seat is removed. Given the vehicle’s age and low mileage, the buyer should also examine age‑related items that are not captured by the MOT. Inspect the tyre tread depth and sidewalls for cracking, dry‑rot or the lingering effects of the 2021 bulge – any uneven wear may indicate alignment or suspension issues. Check the condition of the suspension bushes, ball joints and shock absorbers for any creaking or looseness, especially after the car has been stationary for long periods. Verify the 12‑volt battery’s cranking voltage and assess whether it has been replaced recently, as batteries can lose capacity after several years even with few miles. Examine the under‑body for rust, especially around the wheel arches and exhaust system, and confirm that all fluid changes (engine oil, brake fluid, coolant) have been performed on a calendar basis, not just by mileage. A full service book with stamps will give confidence that the Fiesta has been maintained in line with Ford’s recommendations despite its modest use.
