2021 Mazda 2 Gt — MOT failures & pass rate
Across 3,899 MOT tests, the 2021 Mazda 2 Gt recorded a 94.7% pass rate. That is 3.3 percentage points better than all cars of a similar age, which fail at 8.6%. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (2.9%) and visibility (2.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and brake pads — headlamp aim alone was recorded 92 times.
Tyres is the most common advisory, noted on 14.2% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 2 Gt
The failure pattern for this year is specific enough to inspect against: tyres accounted for 2.9% of tests. Start there.
- Tyres (2.9% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (2.0% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (1.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
