2020 Suzuki Sx4 S Cross Sz5 Boosterjet A

CarHunch analysed 125 real MOT records for the 2020 Suzuki Sx4 S Cross Sz5 Boosterjet A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2020 SX4 S-Cross is a genuinely reliable proposition: a 93% first-time pass rate sits well above the UK average of 80%, and only 6.4% have ever recorded a dangerous defect—meaning serious safety issues are rare. The petrol engine delivers consistent results across the board with a 92.9% pass rate.

At just under 21,000 miles on average, these cars are running lightly for their age, which explains the low failure rate of 0.3 per vehicle. When issues do show up, they're typically minor (1.6 advisories per car on average), so budget for routine maintenance rather than structural repairs—but do get a pre-purchase inspection to check suspension and brake condition, as these components accumulate wear even on lightly-used cars.

What to check before buying a 2020 Suzuki Sx4 S Cross Sz5 Boosterjet 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.
