Takeaway: the Mazda 6’s pass rate has improved over the period (best year 2022 at 71%). Buying used? Budget for pre-MOT checks — brakes, suspension and tyres are the usual culprits.

Reading the Mazda 6’s numbers
The Mazda 6 fails its MOT first time more often than the average UK car — 70.2% pass against 71.4% nationally, across 67,352 real tests. Budget for pre-MOT checks, particularly on older examples. Pass rates reflect the age and upkeep of the cars tested as well as the design — an older fleet drags a model’s rate down.
On safety, the Mazda 6 carries a Band B real-world outcome grade: of the 506 people injured while travelling in one over five years of police records, 14.23% were killed or seriously injured — a better outcome share than 56% of the 129 models we grade. This is a real-world measure shaped by who drives the car and where, not a crash-test score — check its Euro NCAP rating alongside.
