2014 Hyundai I40 1.7L Diesel · EF14 HBJ

The Hyundai i40’s most recent MOT test on 2026-03-21 confirms it passed without defects, though the preceding test on 2026-03-10 failed—an unusual but documented anomaly. The last three valid tests (2025-02-14, 2023-11-17, and 2022-11-17) all passed cleanly, suggesting a stable maintenance pattern over the past four years. The failure in early 2026, however, raises questions about whether the vehicle was driven immediately after the failed test or if there was a delay in rectifying the issue. The absence of defects in the latest pass does not guarantee the underlying cause of the failure was resolved, particularly if it involved a non-visible component like emissions or electrical systems. The recorded mileage of 126,869 miles over approximately 12 years indicates average annual usage, with roughly 10,572 miles per year. There are no significant gaps in testing that would imply prolonged neglect, though the 15-month gap between the 2023 and 2025 tests is slightly longer than the typical 12-month interval. The lack of mileage jumps or abrupt drops suggests consistent driving habits rather than periods of inactivity or heavy usage. Still, the mileage range places the vehicle firmly within the high-wear zone for components like suspension bushes, brake calipers, and drivetrain fluids, which should be scrutinised. Given the sparse defect history, a buyer should prioritise an inspection of the suspension system—particularly the rear bushes and coil springs—for excessive wear or corrosion, as these are common failure points at this mileage. The brakes, while not explicitly flagged, warrant close examination for uneven wear, binding calipers, or corrosion on the discs and pads, especially if the vehicle was driven shortly after the 2026 failure. Structural integrity, including underbody and wheel arch corrosion, should also be checked, as rust can compromise the chassis and subframe over time. Finally, verify that the failed 2026 test was addressed—if the issue was emissions-related, recent modifications could affect performance or fuel efficiency.
