2012 Hyundai I40 1.7L Diesel · RE62 ADV

The Hyundai i40’s most recent MOT test on 2025-09-11—just ten months ago—confirms the vehicle passed without defects, though it failed the prior test on 2025-09-08 at 66,969 miles, a mere 30 miles before passing. This back-to-back failure and pass pattern suggests a narrowly avoided critical issue rather than a consistent maintenance trend. The lack of recorded defects across all five tests implies no recurring mechanical failures, but the proximity of the 2025 failures warrants scrutiny of components prone to sudden degradation, particularly at higher mileages. The most recent pass at 66,999 miles indicates the vehicle remains roadworthy under current MOT standards, though the brief window between failure and pass raises questions about whether underlying issues were addressed or merely masked. The recorded mileage of 66,999 miles over 14 years—approximately 4,786 miles annually—is unusually low for a vehicle of this age, suggesting either minimal use or prolonged periods of inactivity. The gap between the 2023 test at 42,335 miles and the 2024 test at 55,018 miles represents roughly 12,683 miles in a single year, a sharp increase compared to the preceding intervals. This spike could indicate a change in usage patterns, potentially accelerating wear on suspension bushes, coil springs, and brake components. Conversely, the consistency of passing tests without defects suggests the vehicle was likely stored or driven under controlled conditions, reducing exposure to severe environmental or mechanical stress. Given the absence of recorded defects, a buyer should prioritise an in-person inspection of high-wear items that often fail without warning, such as the rear brake calipers and discs—particularly if the 2025 failure was related to binding brakes. The suspension system, including bushes and shock absorbers, should be checked for uneven wear or corrosion, especially given the mileage spike between 2023 and 2024. Structural integrity, particularly around wheel arches and sills, should also be assessed for corrosion, as long-term low-mileage vehicles can develop hidden rust issues from moisture retention. Finally, the exhaust system and emissions components should be inspected for leaks or blockages, as these are common failure points in vehicles approaching 150,000 miles.
