Suzuki Swace Sz-T Hev MOT pass rate & common failures
3,232 MOT tests on the Suzuki Swace Sz-T Hev (2020–2023) give it a 92.1% pass rate. That is effectively the same as all cars of a similar age (8.5% fail rate), so the MOT record here is unremarkable in either direction. 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 (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 123 times.
Mileage matters less than usual here: the Swace Sz-T Hev fails 5.4% of the time in the 0-30k band and 6.5% at 120-150k, a spread of only 1.1 points.
Advisories point at the next bill rather than this one: tyres was flagged on 19.6% of tests without failing them.
The trend is worsening — 0.0% of tests failed in 2022 against 8.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a Suzuki Swace Sz-T Hev
- 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 (4.3% 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 (2.2% 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.
