2020 Mazda CX-30 SE-L Mhev Auto 2.0L Petrol · KM20 TFV

The Mazda CX-30 SE-L in question demonstrates a stable roadworthiness trend over its MOT history, with the most recent test on 2026-02-26 confirming full compliance at 44,428 miles. There are no recorded defects across any of the five tests, though the single failure in February 2024 at 25,587 miles—just one mile before passing the previous test—appears anomalous and lacks specific fault details. This suggests the vehicle has not experienced recurring mechanical issues, though the lack of advisories or warnings in any report means critical components like suspension bushes, coil springs, or binding calipers were not flagged during testing. The absence of emissions-related failures also indicates the hybrid system has not triggered a major service concern. Mileage progression shows consistent usage without abrupt spikes or prolonged inactivity. The vehicle accumulated approximately 9,449 miles between tests in 2024 and 2025, averaging around 7,400 miles annually—a rate typical for its age. The gap between the 2025 and 2026 tests (9,449 miles) aligns with this pattern, and there is no evidence of extended periods of disuse that could accelerate wear on fluids, seals, or suspension components. The near-identical mileage at the 2024 failure and pass (25,587 vs. 25,590) suggests either a minor administrative oversight or a component nearing its limit that was just barely compliant at the time. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-wear items not explicitly tested under MOT standards. Focus on the suspension—particularly the rear coil springs and bushes—given the vehicle’s hybrid weight distribution, as these are prone to fatigue over 44,000 miles. Brake discs and pads, while not failed in testing, should be checked for uneven wear or binding calipers, especially if the vehicle has been driven aggressively. Examine the subframe and wheel arches for corrosion, as MHEV systems often introduce moisture risks to electrical components and joints. Finally, verify the hybrid battery health, as degradation is not detectable via MOT and can manifest as reduced efficiency or warning lights. The lack of advisories does not preclude these areas from requiring attention.
