2021 Mazda CX-5 Sport Auto 2.0L Petrol · BU21 ACJ

The vehicle most recently passed its MOT on 19 December 2025 with no defects or advisories recorded, continuing a consistent pattern of clean test results across the documented history. Three consecutive passes in January 2024, January 2025, and December 2025, each free from advisory notes, suggest a stable and well-maintained mechanical condition from an official roadworthiness standpoint. While a clean MOT record is reassuring, it should be noted that this only confirms the vehicle met minimum statutory criteria at the time of testing and does not necessarily guarantee that all consumables and serviceable items are in optimum condition between tests. The absence of recurring advisories relating to brake wear, suspension components, tyres, or corrosion indicates there have been no flagged deterioration trends in the recent testing cycle. With 29,468 recorded miles over approximately five years, this Mazda CX-5 is averaging around 5,894 miles per year, which is considerably below the typical UK annual mileage of 7,000 to 10,000 miles. Such low usage can reflect a vehicle used predominantly for short journeys, commuting, or one that has spent extended periods stationary. While lower mileage generally means less wear on internal drivetrain components such as the engine, gearbox, and clutch, prolonged standing periods introduce their own concerns. Brake discs and calipers are particularly susceptible to surface corrosion from infrequent use, and the automatic transmission and associated fluid can degrade over time regardless of distance covered. The relatively short gaps between MOT tests with consistent, low implied annual mileage supports a picture of either light regular use or seasonal/occasional use with periods of inactivity. Given the clean MOT history and the low-mileage profile, a prospective buyer should focus on age-related deterioration rather than wear from high use. Tyre sidewalls should be carefully inspected for cracking, perishing, or ozone damage, as rubber compounds degrade with calendar age even on low-mileage vehicles; check the production date on the sidewall and consider replacement if the tyres are over five years old regardless of tread depth. Examine the brake discs for any signs of significant surface rust or, more importantly, any lipping or corrosion pitting that might indicate calipers have been binding due to infrequent operation. The 12V battery is another priority check, as batteries left partially discharged through short trips or extended standing can suffer reduced capacity; a load test or voltage check is advisable. Additionally, verify that all time-based servicing has been conducted, including engine oil and filter changes, brake fluid replacement (typically every two years regardless of mileage due to hygroscopic fluid degradation), and inspection of the automatic transmission fluid for condition and level. On the road, particular attention should be paid to any brake shudder or vibration under firm application, which could indicate disc corrosion or uneven wear from standing. Listen for any clunks or knocks from the suspension over uneven surfaces, which may suggest dried or perished bushes given the vehicle's age, even at low mileage. The automatic gearbox should shift smoothly through all ranges without hesitation, flare, or harsh engagement, and any fluid leaks beneath the vehicle after standing should be investigated. Finally, confirm the service book history and verify that Mazda main dealer or specialist servicing stamps are present at the correct intervals, as a well-documented maintenance record is arguably more telling for a low-mileage vehicle than the MOT history alone.
