2021 Mazda CX-30 SE-L LUX Mhev 2.0L Petrol · BU21 DHE

The 2021 Mazda CX-30 SE-L LUX MHEV presents a stable and improving maintenance trend, culminating in a clean pass on 7 May 2026 at 50,604 miles with zero defects recorded. That result is a marked contrast to the 2025 test, where the tester flagged multiple items approaching service limits. The absence of any advisories or failures in the most recent entry suggests the previous owner addressed those worn components promptly, which is a positive indicator of responsible upkeep rather than neglect. The mileage progression tells a consistent story. Between the May 2025 test at 38,481 miles and the May 2026 test at 50,604 miles, the car covered 12,123 miles in twelve months, up from the 12,641 miles recorded between May 2024 and May 2025. Annual mileage has remained steady at roughly 12,000 to 12,600 miles, which is slightly above the typical 10,000-mile benchmark for a five-year-old vehicle but not excessive. There are no suspicious gaps or sudden jumps in the odometer record that would raise concerns about clocking or prolonged standing. The 2025 test is the key diagnostic snapshot. Both front brake pads were wearing thin, and all four tyres were flagged, with the fronts down to 2mm and the rears noted as worn close to the legal limit. The fact that none of these items reappeared in the 2026 record implies the pads and tyres were replaced within the year. Buyers should still verify the condition of the current brake discs and pads in person, as aggressive use of new pads on scored or worn discs can lead to premature binding or uneven braking. The undertrays fitted at both the 2024 and 2025 tests suggest the car has been maintained with some care, but their presence also means a buyer should request the undertrays be removed for a proper inspection of the subframe, suspension mounts, and exhaust for corrosion or oil weeping. Structurally, the clean 2026 result is reassuring, yet the lack of any advisories across the entire three-test history is unusually sparse for a five-year-old car. A physical inspection should focus on the suspension bushes, coil springs, and shock absorbers for signs of perishing or oil misting, as well as the steering rack boots and track rod ends. The exhaust system, particularly the flexi-joint and catalytic converter, deserves a close look given the MHEV system's sensitivity to back-pressure and emissions sensor faults. Tyre wear patterns on the current set will also reveal whether the tracking and geometry remain within specification, especially given the edge wear noted on the fronts in 2025.
