MX-30 fuel types
Most Mazda MX-30 cars tested in 2025 were electric. Electric cars need an MOT from three years old like any other car, and their tyres, brakes, suspension and lights are tested the same way.
Where the MX-30 fails its MOT
Where Mazda MX-30 cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were tread depth below requirements of 1.6mm (17.6%), condition has a cut in excess of the requirements deep enough to reach the ply or cords (17.4%) and wipers does not clear the windscreen effectively (13.3%). See every common MX-30 MOT failure.
These are DVSA failure records across every Mazda MX-30 that failed, not a claim that every MX-30 has these problems.
What should you check when buying a used MX-30?
The areas above, most common first, and what an MOT tester looks at in each.
1
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 44% of MX-30 failure items.
2
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 23.7% of MX-30 failure items.
3
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 15.2% of MX-30 failure items.
4
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 7.7% of MX-30 failure items.
5
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 5.3% of MX-30 failure items.

What the MOT record doesn't tell you
Knowing Mazda MX-30 failures cluster around tyres and visibility tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Mazda MX-30 FAQs
Is the Mazda MX-30 reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 90.4% first-time pass rate for the Mazda MX-30 across 2,898 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used Mazda MX-30?
On the car itself, start with the areas it most often fails on: tyres, visibility and lamps, reflectors and electrical equipment. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a Mazda MX-30's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
