2017 Ford Fiesta 1.5L Diesel · LL66 GFG

The 2017 Ford Fiesta presents a mixed maintenance picture. The most recent MOT on 2 April 2024 at 156,436 miles passed, but only after a same-day failure flagged a malfunctioning tyre pressure monitoring system, a deteriorated bonnet primary retaining device, and an unidentified brake noise suspected to be anti-rattle shims. The prior two tests in April 2022 and April 2023 were clean passes, suggesting the vehicle was reasonably maintained until early 2024, when several minor but notable faults accumulated in a short window. The trend is not clearly worsening, but the sudden appearance of multiple advisories and a system fault after two consecutive clean passes raises questions about whether routine checks were neglected in the months leading up to the 2024 test. The mileage accumulation is notably high for a nine-year-old supermini. Between April 2022 at 131,535 miles and April 2024 at 156,436 miles, the car covered 24,901 miles in two years, averaging over 12,000 miles annually in that period alone. The earlier years appear to have been used more gently, with 14,767 miles added between April 2022 and April 2023. This uneven pattern suggests a shift toward heavier use more recently, which places greater stress on consumable components, particularly brakes, tyres, suspension bushes, and drivetrain joints. A buyer should pay close attention to the rear suspension, which has a documented history of structural wear. In the April 2022 failure at 131,517 miles, both rear axle swivel pins and bushes were excessively worn, the nearside rear coil spring was fractured, and the nearside front track rod end had excessive play. Although the subsequent two tests passed, coil spring fractures and worn axle bushes on a Fiesta of this age and mileage often point to underlying corrosion or long-term load stress rather than a one-off defect. Inspect the rear subframe mounting points, spring seats, and axle beam for fresh corrosion, cracking, or evidence of poorly executed repairs. The brake noise flagged in April 2024, combined with the squeaky auxiliary belt and the deteriorated bonnet catch, suggests minor but persistent issues were left unaddressed. Have a technician inspect the rear brake calipers and discs for binding or uneven wear, verify the condition of the auxiliary belt tensioner and pulleys, and check the bonnet secondary catch for correct operation. At 156,436 miles, this Fiesta is entering the zone where suspension bushings, track rod ends, and brake components are approaching replacement intervals, so a thorough underbody inspection is essential before purchase.
