2017 SEAT Leon 1.4L Petrol · YA67 GPK

The maintenance trend for this SEAT Leon shows a recent significant deterioration, culminating in a serious failure immediately before its December 2025 pass. On 3 December 2025 at 47,168 miles, the tester flagged catastrophic rear suspension failures, recording serious fluid leaks on both rear shock absorbers and fractured coil springs on both sides of the vehicle. A failed wiper blade accompanied these severe structural defects. The car passed the retest the following day with zero defects, indicating the rear suspension components were replaced. Despite this repair, the sudden failure of both rear coil springs and shocks suggests either a severe manufacturing defect, poor previous repair work, or prolonged periods of standing causing perished rubber and metal fatigue. The trend is currently stable following the repair, but the nature of the failure warrants extreme caution. The recorded mileage of 47,168 miles is notably low for a 2017 vehicle, averaging roughly 5,241 miles per year. The history shows a gap of over ten thousand miles between December 2023 at 29,050 miles and November 2024 at 36,631 miles, representing a typical annual cycle. However, the mileage then plateaued entirely, recording the exact 47,168 miles on both the failed and passed tests in December 2025. This stagnation over the last six months suggests the vehicle has been standing unused for an extended period. Prolonged stationary storage often causes flat-spotted tyres, seized brake components, and degraded suspension bushes, which aligns with the sudden suspension collapse and the front brake imbalance and fluctuation recorded in November 2024. A prospective buyer must conduct a thorough physical inspection of the rear subframe and suspension mounting points. The simultaneous fracture of both rear coil springs and the failure of both shock absorbers raise immediate concerns about the structural integrity of the rear chassis. Inspect for corrosion, accident repairs, or substandard replacement parts used in the December 2025 repair. The front braking issues from the November 2024 test, showing imbalance exceeding 50 per cent and excessive fluctuation, indicate warped front brake discs or binding calipers that may have deteriorated further during the recent period of inactivity. Examine the offside edges of the tyres for uneven wear, and check the condition of the rear dampers for fresh paint or overspray that might mask a rushed repair. Verify the operation of the rear suspension over uneven surfaces, listening for knocking from worn suspension bushes that often accompany shock absorber replacement if not replaced concurrently.
