2018 KIA Stonic 1.6L Diesel · C8 DNE

A recurring theme across the MOT record is progressive wear on the braking system combined with a few isolated suspension‑related failures; the latest 2026 test still flagged front disc scoring and a modest oil seep, while a separate failure on the same day highlighted a compromised nearside track‑rod dust cover that no longer shields the joint from contaminants. Earlier years added a dangerous off‑side rear‑pad thickness issue and a serious fluid leak from the off‑side rear shock absorber, indicating that brake and suspension components have required attention on several occasions rather than the vehicle being uniformly clean. At 60,088 mi the car averages just over 7,500 mi per annum, a mileage rate that sits comfortably within normal usage for a 2018 model. The MOT history shows a full set of annual tests with no prolonged gaps, suggesting the vehicle has been driven regularly rather than sitting idle for extended periods. This steady kilometre accumulation aligns with the observed wear on the discs and pads, as front‑disc scoring typically accelerates after 50‑60 k mi, while the rear‑pad wear manifested earlier, possibly due to aggressive braking or load conditions. Prospective buyers should verify the condition of the front brake discs and pads by measuring disc thickness and inspecting for deep scoring or cracking; any pulsation or grinding under braking, especially when the pedal is applied firmly, would confirm the need for replacement. The off‑side rear‑pad issue recorded in 2024 must have been remedied – confirm that new pads are fitted and that the caliper moves freely without binding. The nearside track‑rod dust‑cover damage warrants a close visual inspection of the ball‑joint and surrounding rubber boot for dirt ingress, corrosion, or excessive play, and a test‑drive should include listening for clunks when steering over bumps and checking for any steering pull. The oil‑leak advisory appears on every MOT since 2025, so locate the source – common points include the valve‑cover gasket or oil‑filter housing – and look for fresh oil spots on the ground and oil residue in the engine bay. While the leak is classified as non‑excessive, persistent seepage can lead to reduced oil levels and potential engine wear if not addressed. A qualified pre‑purchase inspection should also assess the rear shock absorber for any renewed fluid loss, verify the integrity of suspension bushes and coil springs, and ensure that any previously repaired components have been correctly re‑installed and are free of corrosion.
