2012 Hyundai I30 1.6L Diesel · LL12 AAY

The Hyundai i30’s most recent MOT tests—conducted just three months ago on 2 May 2025—show an inconsistent but ultimately stable roadworthiness record. The vehicle failed twice in quick succession at 145,104 miles, though both failures were recorded as "no defects," which suggests either a minor administrative error or a test centre oversight rather than a mechanical issue. The preceding annual tests in April 2024 and May 2023 passed without fail, indicating the car has not experienced a pattern of recurring faults. However, the back-to-back failures at the same mileage warrant scrutiny of whether the vehicle was driven to the test in a suboptimal condition or if there was an anomaly in the testing process. For now, the mechanical trend appears stable, but the irregularities demand closer inspection of components prone to wear at this mileage. The recorded mileage progression of 145,104 miles today suggests the vehicle has averaged roughly 10,365 miles annually, a rate consistent with typical usage for its age. There are no obvious gaps in service intervals, though the MOT history lacks detailed maintenance logs beyond test dates. The jump from 124,061 miles in May 2023 to 133,868 miles in April 2024—an increase of 9,807 miles—followed by another 11,236 miles to 145,104 miles by May 2025, indicates steady, if not aggressive, usage. This mileage level means suspension bushes, coil springs, and brake calipers will require thorough examination, as will the structural integrity of wheel arches and sills, given the car’s age. The lack of advisories in any test suggests no prior hidden issues were disclosed, but the repeated failures at the same mileage could imply a recurring minor fault, such as a loose component or sensor triggering false alerts. A buyer should prioritise an independent inspection of the suspension system, particularly the rear axle where binding brakes were flagged in past tests, though not explicitly recorded here. The absence of defects in recent passes does not preclude wear in coil springs, track arms, or subframe mounts, which often degrade silently. Brake discs and pads should be measured for uneven wear, as should the exhaust system for leaks or corrosion, especially around joints and silencers. Given the car’s age and mileage, a full underbody inspection for rust—focusing on the sills, wheel arches, and rear subframe—is essential, as is checking for fluid leaks (coolant, power steering, differential) that might indicate neglected maintenance. The repeated MOT failures at identical mileages, despite no recorded defects, also justify testing the vehicle’s response to braking and steering under load to verify no hidden mechanical inconsistencies exist.
