2016 Hyundai I40 1.7L Diesel · EJ66 FVV

The 2016 Hyundai i40 presents a largely stable maintenance picture through its MOT history, though the most recent test on 21 February 2026 at 122,919 miles introduced a notable advisory. The offside rear shock absorber was flagged for a light misting of oil under item 5.3.2 (b), indicating early-stage fluid seepage at the damper seal. This is not an immediate failure, but it marks the first defect recorded in five consecutive passes and suggests the rear suspension damping is beginning to deteriorate. The trend had been clean and consistent from 2022 through 2025, so this single advisory represents a minor downward shift rather than a systemic decline. The mileage accumulation tells a clear story of sustained high use. The vehicle has covered 122,919 miles over roughly ten years, averaging approximately 12,292 miles per year, which sits above the typical annual figure for a car of this age. The progression between tests is fairly steady: 68,723 miles in February 2022, 88,738 in February 2023, 102,022 in February 2024, 114,626 in February 2025, and 122,919 in February 2026. Each annual interval shows between roughly 13,000 and 20,000 miles, with the largest jump occurring between 2022 and 2023. There are no suspicious gaps or sudden drops in recorded mileage that would suggest odometer tampering or prolonged periods off the road. The record is clean and continuous, which supports the conclusion that this car has been driven regularly and kept in active service. A buyer inspecting this i40 in person should focus on the rear suspension, given the flagged shock absorber. The offside rear damper's oil misting could progress to full fluid loss over time, reducing damping effectiveness and potentially accelerating wear on the coil spring seat and top mount. Check for uneven tyre wear on the rear axle, which would confirm compromised damping. At 122,919 miles, the front suspension components, including lower arm bushes, drop links, and anti-roll bar links, are also likely approaching the end of their service life and should be examined for play or perishing. The brake system merits close attention as well. High-mileage use places repeated thermal and mechanical stress on discs, pads, and calipers, and binding or uneven wear would not be unexpected at this stage. Beyond the suspension and brakes, inspect the underside for corrosion, particularly around the subframe, suspension mounting points, and inner wing arches. A decade of high-mileage driving, especially on salted winter roads, can produce significant surface corrosion that may not yet constitute an MOT failure but could affect long-term structural integrity. The exhaust system should also be checked for corrosion and gas leaks, as high annual mileage accelerates deterioration of the manifold, catalytic converter, and silencer box. Tyre condition and tread depth across all four corners will reveal whether the previous owner maintained basic consumable upkeep, and any uneven patterns should prompt a full four-wheel alignment check.
