2016 Hyundai I40 1.7L Diesel · DV16 MVX

A recurring brake-related theme runs through this Hyundai i40's MOT history and is the single mechanical point worth weighing carefully before purchase. The 2024-11-27 test recorded an offside front service brake excessively binding failure, and two years earlier on 2022-11-09 an advisory was raised for the offside rear service brake binding, alongside rear brake pads noted as wearing thin. Binding calipers are not a one-off anomaly here; they appear on the same axle side across separate tests, suggesting a persistent or slowly developing issue with the offside braking mechanism rather than a transient fault cleared at the time. Against this, the intervening tests in 2021, 2023, 2025 and the most recent pass on 2026-08-04 returned no defects, so the binding condition appears intermittent or progressive rather than constant, but the pattern is too consistent to dismiss. Recent roadworthiness has held, but the offside braking circuit is the defined weak point in an otherwise largely unremarkable record. Mileage accumulation is on the higher side for a ten-year-old i40, with 123,661 recorded miles averaging roughly 12,300 per year. There are no extended gaps in the MOT record itself, with annual or near-annual tests stretching continuously back to 2020, which suggests the vehicle has been in regular use rather than laid up. However, the figure between the 2025-12-03 and 2026-08-04 tests jumps by around 13,000 miles in only eight months, indicating very heavy recent use, likely long-distance motorway mileage given the clean emissions and braking record. Mechanically, this combination of sustained annual use and a recent high-mileage period means consumables such as brake pads, discs, tyres, drive belts and suspension components will have been worked harder than the calendar age alone implies. Front suspension arms, bushes and anti-roll bar drop links on i40s of this generation are known to wear progressively with mileage, and the higher the annual accumulation the sooner those parts reach service limits. Given the binding-brake advisories and failure, particular attention should be paid to the offside front caliper, slider pins and guide surfaces during any inspection. On a test drive, listen for any drag or pulling sensation when releasing the brake pedal, feel for the car pulling to the nearside under light braking, and check whether the offside front disc runs noticeably hotter than the nearside after a short drive. A binding caliper left unattended can glaze a disc unevenly and accelerate pad wear on the opposite side, so even though the most recent test passed clean, the discs and pads on both sides should be physically measured for thickness and checked for lipping or uneven wear. The 2022 advisory also mentioned thin rear pads, so rear pad and disc condition should be confirmed even if no current advisories are flagged. Tyre condition warrants a brief physical check too. The 2020 test recorded cracking and perishing on the nearside front and both rear tyres, an advisory that tends to recur on vehicles covering high annual mileage, as heat cycling accelerates sidewall deterioration. Inspect the sidewalls for any hairline cracks, check for uneven shoulder wear which can indicate suspension geometry misalignment, and verify that all four tyres are of matching type and tread depth. Beyond the flagged items, the higher-than-average mileage makes it worth raising the vehicle on a ramp to inspect front suspension arms, anti-roll bar bushes, engine and gearbox mounts, and any signs of oil seepage from the power steering rack, all of which are wear items that scale with miles rather than years on this model.
