2022 Mazda CX-30 2.0L Petrol · AE72 JGV

The defining mechanical story of this 2022 Mazda CX-30 is one of largely uneventful roadworthiness, with the single recorded MOT test on file passing without any failures or refusals. The test, carried out on 16 September 2025 at 43,333 miles, did however raise two advisories that a prospective buyer should treat as early indicators of wear rather than ignore. An offside rear tyre was noted as worn close to the legal limit and worn on the edge, suggesting either an alignment irregularity or uneven pressure management on that corner, while the front brake pads were flagged as wearing thin at 3mm of friction material remaining. Both advisories are non-fail items at the point of test but represent components approaching the threshold where replacement becomes necessary before the next examination. Against an age of roughly four years, the recorded mileage of 43,333 equates to an annual accumulation of approximately 10,833 miles, which sits within typical parameters for a privately used compact SUV of this type. There are no extended gaps in testing history to suggest prolonged periods off the road, and no evidence in the available record of mileage inconsistencies or unusually rapid accumulation between tests. For the prospective buyer, this means wear patterns on the major mechanical assemblies should broadly reflect steady, normal service use rather than the elevated degradation sometimes seen on high-mileage vehicles or the specific concerns, such as seized brake calipers or dried suspension seals, that can accompany long stationary periods. Given the advisory concerning the offside rear tyre wearing on its edge, it is prudent to carry out a careful inspection of the rear suspension geometry and tyre condition at viewing. Uneven shoulder wear on a single rear tyre can point to issues with the rear trailing arm bushes, a weakened coil spring allowing the wheel to sit out of position, or worn shock absorber damping that affects wheel alignment under load. During a test drive, listen for clonking or knocking from the rear over uneven surfaces and feel for any vagueness or tramlining through the steering, particularly over undulating roads. A quick check on a level surface for uneven ride height at the rear, or excessive bounce after pressing down on each rear corner, would also be worthwhile. The front brake pad advisory at 3mm remaining indicates that replacement is likely due within the next service interval, and this warrants direct attention on a test drive. Under moderate braking from around 30 to 40 mph, any vibration through the pedal, a juddering sensation, or a pronounced steering wheel shake could suggest the brake discs have worn unevenly or developed lipping and would benefit from machining or replacement alongside the pads. Listen also for any binding or grinding noises on light application, which can indicate a seized guide pin or sticking caliper piston, both of which are worth excluding. On the road, the car should track straight under braking without pulling to either side, and the pedal should feel firm and progressive rather than soft or spongy, which would confirm the hydraulic system remains sound.
