2016 Hyundai I40 1.7L Diesel · EY16 EFC

This 2016 Hyundai i40 holds a current MOT valid until 18 October 2025, issued at 117,727 miles. The overall maintenance picture is broadly stable but carries a notable structural caveat. The most recent test passed, yet the tester flagged an oil leak, general underbody corrosion, and a rear sub-frame noted as corroded but not seriously weakened. These are not fresh failures, but they are active observations that warrant close physical inspection before purchase. The mileage progression is consistent and unremarkable for a vehicle of this age. Between the October 2023 test at 85,474 miles and the October 2025 test at 117,727 miles, the car covered roughly 32,253 miles in two years, averaging around 16,000 miles annually. That is slightly higher than the lifetime average of approximately 11,773 miles per year, yet it remains within a normal range and does not suggest unusually harsh use. The record shows no large gaps or suspicious jumps in the odometer, indicating regular annual testing and steady use. The failure history reveals a pattern of deferred consumable replacements rather than chronic mechanical neglect. In October 2024, both rear tyres were cut deep enough to expose ply or cords, the nearside rear brake pads were below 1.5 mm, the nearside rear service brake was excessively binding, and the offside front ABS wire bracket was broken. All of these were rectified ahead of the pass the following day. A year earlier, in October 2023, front brake pads were again below minimum thickness and the nearside front tyre had exposed ply, suggesting tyre and brake upkeep was reactive rather than proactive. Buyers should physically check the condition of all four tyres, measure pad thickness front and rear, and test each caliper for binding or uneven wear. The corrosion observations are the most significant long-term concern. The 2025 test explicitly recorded underbody corrosion and a corroded rear sub-frame, albeit assessed as not seriously weakened at the time of inspection. A buyer should have the vehicle raised on a lift to examine the sub-frame, suspension mounting points, sills, and brake lines for advanced rust, particularly around the rear axle area. The minor oil leak noted in 2025 should also be traced to its source, whether a rocker cover gasket, oil filter housing, or crankshaft seal, to gauge repair cost and potential engine oil loss between services.
