Every Mazda 3 model year
Pass rates fall as cars age, so the only fair comparison for a 2012 car is other cars of the same age. The full run for the Mazda 3:

What this means if you are buying a 2012 3
The 2012 sits close to the Mazda 3 average, so there is no strong model-year signal either way. Judge the individual car on its own history. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 14-year-old car fails on
A 2012 car is 14 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 2012 Mazda 3 the average at test was 90,671 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
The strongest year for this model is 2021 at 92.9%, and the weakest in our data is 2004 at 57.4%. That 35.5 point spread across the model's life is why comparing a 2012 car against a newer one tells you very little.
