2017 SEAT Leon 1.8L Petrol · Y9 JCK

The 2017 SEAT Leon presents a mixed mechanical picture as of its most recent MOT activity. The vehicle passed on 8 September 2025 at 133,050 miles, but only after a failed attempt on the same day at the identical mileage. That initial failure flagged a headlamp aim defect, which was rectified before the retest passed. Both the pass and fail records also note binding service brakes on both front wheels, though not excessively, along with a windscreen damage advisory that did not affect the driver's view. The maintenance trend is broadly stable rather than clearly improving or worsening, but the recurring front brake binding across both visits suggests a persistent issue that was tolerated rather than properly resolved. The mileage accumulation is notably uneven. Between 1 September 2023 at 78,269 miles and 5 September 2024 at 106,196 miles, the car covered 27,927 miles in twelve months, a sharp increase from the prior annual average. Then, between 5 September 2024 and 8 September 2025, the odometer moved just 26,854 miles over the same period, still high but slightly reduced. The overall annualised figure of roughly 14,783 miles is well above typical use for a nine-year-old car, and the concentrated accumulation in 2023 to 2024 points to sustained high-demand driving, likely motorway or fleet use, which accelerates wear on consumables and running gear. A buyer should pay close attention to the front braking system. Binding calipers on both sides, noted in the most recent test, can cause uneven pad wear, overheating of discs, and reduced fuel economy if left unaddressed. The 2024 failure also revealed rear brake pads wearing thin and rear discs that were worn, pitted, or scored, indicating the braking system has been under sustained load. Suspension demands equal scrutiny. Both rear shock absorbers were recorded with serious fluid leaks in September 2024, yet the September 2025 test passed without any suspension defect, meaning they were presumably replaced. A physical inspection should confirm this repair was carried out to a proper standard and check for any remaining play in bushes, drop links, and front dampers, which are common wear points on high-mileage VAG-platform vehicles. The 2024 failure also exposed structural tyre damage across three corners, with tears caused by separation or partial failure of the tyre carcass. This pattern suggests the previous owner was running budget or aged rubber under load, a concern given the car's high mileage. The windscreen chip noted in 2025 may have since worsened, so a close visual check is warranted. Overall, the Leon is roadworthy on paper, but the combination of persistent brake binding, heavy mileage, and a history of deferred suspension and tyre issues means a thorough on-the-ground inspection by a qualified mechanic is essential before purchase.
