The Mazda 6 S has an overall MOT pass rate of 69.8% across 325 real MOT tests — roughly in line with the UK average.
The most common problems on the Mazda 6 S are tyre tread depth below requirements of 1.6mm (4 recorded failures), position lamp(s) not working (4), and brake pad(s) less than 1.5 mm thick (3). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical Mazda 6 S owner drives around 7,003 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
