Suzuki Sx4 S Cross Sz T B Jet MHEV A (2021)
2021 Suzuki Sx4 S Cross Sz T B Jet MHEV A
CarHunch analysed 148 real MOT records for the 2021 Suzuki Sx4 S Cross Sz T B Jet MHEV A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2021 SX4 S-CROSS is a genuinely reliable proposition, with a 93.3% first-time MOT pass rate that significantly outpaces the UK average of 80% and a dangerous defect rate of just 6.1%, well below concern territory. The hybrid powertrain appears to be wearing well so far, backed up by an average of only 0.19 failures per vehicle across the cohort.
At just under 20,000 miles median mileage for a three-year-old car, these vehicles are relatively lightly used, which naturally helps explain the strong pass rates—but the real story is the low advisory count of 0.8 per car, suggesting the engineering is sound rather than simply unblemished by age and miles. If you're considering one, a pre-purchase inspection remains sensible, but this data suggests you're looking at a car that's unlikely to throw expensive surprises at you in the near term.
What to check before buying a 2021 Suzuki Sx4 S Cross Sz T B Jet MHEV A
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.
