2021 Suzuki Swace Sz5 Hev — MOT failures & pass rate
Across 892 MOT tests, the 2021 Suzuki Swace Sz5 Hev recorded a 93.7% pass rate. That is 2.3 percentage points better than all cars of a similar age, which fail at 8.6%. Failures cluster in visibility, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — visibility (3.9%) and tyres (2.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, washers and tread depth — wipers alone was recorded 31 times.
A 60-90k example is materially riskier than a 0-30k one: 9.7% versus 3.5%.
Tyres is the most common advisory, noted on 21.1% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 Swace Sz5 Hev
The failure pattern for this year is specific enough to inspect against: visibility accounted for 3.9% of tests. Start there.
- Visibility (3.9% 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.
- Tyres (2.8% 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.
- Lighting & signalling (1.6% 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.
