Mazda Mx-30 Gt Ev MOT pass rate & common failures
Across 3 model years and 1,647 tests, the Mazda Mx-30 Gt Ev passes its MOT 94.5% of the time. All cars of a similar age fail 8.6% of the time, so this is 3.0pp better than the group it competes with. Its most common failure areas are tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.3%) and visibility (1.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 35 times.
Tyres is the most common advisory, noted on 19.7% of tests — work that passed today but is likely due soon.

What to check before buying a Mazda Mx-30 Gt Ev
- Tyres (4.3% 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 (1.9% 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 (1.0% 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.
