Mazda model reference
Mazda Mazda2
What our record holds on the Mazda2, sold in the UK since 2003: body styles, fuel types and the road tax a used one pays.
No reliability figure is published for the Mazda Mazda2 that this site could cite. What circulates instead is survey data from panels that select themselves, and warranty claim rates published by companies with something to sell.
Any percentage would be our own calculation. Which years count, and whether a facelift and a new generation sharing the Mazda2 name are one model or two, both move the answer, and neither choice is anybody official's.
So the field does not exist. We do not average the other Mazda models into a number and put it here, and we do not push a marque figure down onto the Mazda2. What is real and specific is the paperwork for one car.
No fault ordering is published for the Mazda2
A 2015 1.5 Skyactiv-G at about 117 g/km is band C, £35 for twelve months in 2026/27.
That figure is a worked example for the year and engine named, not a rate for every Mazda2. Read the CO2 figure and the first registration date off the V5C before you budget, because both change the answer.

Buying a used Mazda2: what the record settles
Our record puts the Mazda2's UK sales period at since 2003. That range is the useful starting point, because everything about the cost of running one turns on where a particular example sits inside it. It came in one body style here, hatchback, with 3 fuel types: petrol, diesel and petrol mild hybrid.
The Mazda2 was on sale on both sides of the road tax change of 1 April 2017, and that is the single most useful thing to know before you buy one. An example first registered up to 31 March 2017 is taxed on its CO2 figure under the lettered bands, so engine, gearbox and even wheel size can move two cars of the same year into different bands. One registered from 1 April 2017 pays the flat standard rate instead and its CO2 stops mattering. Two otherwise identical cars a year apart can cost noticeably different amounts to keep taxed, and only the V5C tells you which one you are looking at. There is also a quirk worth knowing on the oldest examples: a car registered before 23 March 2006 cannot be charged above band K however high its emissions, so a thirsty old one can be cheaper to tax than a newer car a class below it.
For running costs the fuel matters more than the badge. On the diesels the emissions section is where a neglected car loses its certificate: the particulate filter is inspected and the smoke reading is measured against a limit, and a filter that has never had a long run to clear itself will not pass on a good intention. A mild hybrid is a petrol car for both the test and the tax: the alternative fuel discount that used to shave a little off the bill ended on 1 April 2025.
None of that is a substitute for the record of the actual car. The invoices name what was replaced, when and at what mileage, and the same job appearing twice in three years says more about a Mazda2 than any statistic about the model ever could. A mileage that goes backwards across a paperwork trail is worth walking away from whatever the badge is.
Mazda has been imported into Britain since the late 1960s and has kept naturally aspirated petrol engines and manual gearboxes in its range longer than most. The MX-5 has been sold here since 1990 and has the strongest specialist parts supply of any modern roadster. Rear arch and sill corrosion on cars from the mid 2000s is the known weak point, and it is worth an inspection rather than an assumption. That is context on the marque rather than on this car, and there is more of it, along with every other model line, on the Mazda page.
