Should I check the MOT history before buying a 2021 Suzuki Swift Sz T Dualjet MHEV CVT?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Suzuki Swift Sz T Dualjet MHEV CVT?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Suzuki Swift Sz T Dualjet MHEV CVT?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Suzuki Swift Sz T Dualjet MHEV CVT reliable?

Based on MOT data from 661 vehicles, the 2021 Suzuki Swift Sz T Dualjet MHEV CVT has a first-time MOT pass rate of 94.8%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Suzuki Swift Sz T Dualjet MHEV CVT?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2021 Suzuki Swift SZ-T is a strong performer with a 93.5% first-time MOT pass rate—well above the UK average of 80%—and only 3.8% of vehicles ever recording a dangerous defect, which suggests this is a genuinely safe and reliable buy. The hybrid powertrain shows no weakness, maintaining that 93.4% pass rate across the vast majority of the 661 vehicles tested.

At just over 16,000 miles median mileage, these cars are still relatively young and lightly used, which partly explains their clean bill of health; the average failure rate of 0.17 per vehicle is impressively low, and advisories averaging 1.0 per car are mostly routine wear items. Before committing, ask the seller for full service history and check that any recorded advisories (typically tyres, brake pad wear, and fluid top-ups) have been addressed, as these cars rarely need serious work at this age.

The 2021 Suzuki Swift Sz T Dualjet MHEV CVT passes its MOT first time more often than most UK vehicles (94.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
