2022 Mazda CX-30 GT Sport Tech Mhev Auto 2.0L Petrol · BX22 XEN

A 2022 Mazda CX-30 with just 21,457 miles and a near-immaculate MOT record presents itself as a lightly used, mechanically tidy proposition, though the absolute mileage figure invites the usual scrutiny associated with low-use vehicles. The latest DVSA test on 26 February 2026 was a pass with only a single advisory noting slight damage, cracking or perishing on the nearside front outer tyre sidewall, while the prior test in March 2025 was issued a completely clean pass with no advisories. Across the recorded history there are no failures, no advisories relating to braking efficiency, suspension components, corrosion, exhaust integrity, lighting or any structural item, which is the strongest possible DVSA outcome for a car of this age. The overall trajectory is therefore one of stability rather than deterioration, with the only outstanding item being a tyre condition advisory that, in isolation, is a routine wear observation. Against an age of approximately four years, the recorded accumulation of 21,457 miles equates to roughly 5,364 miles per year, which is comfortably below the average annual mileage for a UK family crossover. There is a notable gap between the two recorded tests, with the vehicle not appearing at all during 2023 or 2024, and mileage only bookending 2025 and early 2026, so the true year-on-year accumulation cannot be verified from the DVSA file alone. Such a low figure often reflects a mix of genuine light use and extended stationary periods, and mechanically this tends to manifest as premature ageing of rubber components, oxidation of brake discs and calipers from underuse, and potential 12V battery degradation rather than the usual wear from high mileage. Any MOT history by itself cannot confirm whether the annual servicing, fluid changes and under-hood inspections expected of a modern Mazda have been carried out, so independent verification of the service book and supporting invoices would be prudent. With the only recorded advisory being a damaged or perished nearside front tyre sidewall, the immediate priority on inspection is the condition of all four tyres, including the spare or repair kit if fitted, paying close attention to sidewall cracking, bulges, age-related perishing and uneven shoulder wear that might suggest a tracking or suspension geometry issue. On a test drive, listen for any rhythmic thumping or vibration through the steering wheel that could indicate a deformed sidewall, and check that the steering remains centred with no pull to either side over a straight motorway section. Given the low annual mileage and the implied standing time, it is also worth feeling for any binding or judder from the front brakes at low speed, which would suggest corroded caliper slides or pad glazing, and listening for squeal on the first few applications after the car has been parked. Beyond the recorded advisory, the vehicle is a four year old MHEV automatic and therefore warrants a focused check on the items that MOT testing does not fully cover, including the 48V mild hybrid system health, the condition and age of the 12V auxiliary battery, and any diagnostic trouble codes stored in the Mazda i-Activsense and hybrid modules using a dealer-level scan tool. A thorough road test should include a full lock-to-lock steering check to confirm no clonks from the front suspension arms or anti-roll bar bushes, a firm brake application from around 40 mph to verify no judder or pull, and a steady 30 to 50 mph cruise to detect any vibration, drone or hesitation that could indicate transmission or hybrid system issues. Finally, confirming the build date on each tyre sidewall DOT stamp and comparing it against the vehicle registration date will establish whether the rubber is age-worn relative to the mileage, which is often the limiting factor on otherwise lightly used modern cars.
