Suzuki Swift Sz5 Dualjet MHEV CVT (2020)
2020 Suzuki Swift Sz5 Dualjet MHEV CVT
CarHunch analysed 121 real MOT records for the 2020 Suzuki Swift Sz5 Dualjet MHEV CVT. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Swift SZ5 is a genuinely reliable proposition—a 93% first-time pass rate beats the UK average by 13 percentage points, and the 5% dangerous defect rate sits well below the concerning threshold. The hybrid powertrain appears bulletproof so far, with essentially all vehicles running the clean electric variant.
At just under 20,000 miles median age, these cars are still young and lightly used, which partly explains the low failure count of 0.18 per vehicle. What matters for a buyer is that even as these Swifts rack up mileage, the pattern suggests they'll remain straightforward to maintain—grab a pre-purchase inspection focused on the CVT gearbox and hybrid battery health, since those are the components most likely to surprise you later.
What to check before buying a 2020 Suzuki Swift Sz5 Dualjet MHEV CVT
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
