The 2020 Suzuki Vitara SZ5 BoosterJet MHEV is exceptionally reliable by UK standards, with a first-time MOT pass rate of 95.1% compared to the national average of 80%. Only 5.9% of vehicles have ever recorded a dangerous defect, which is reassuringly low and suggests buyers can feel confident about safety-critical systems.
At an average mileage of 28,843 miles for a four-year-old car, these Vitaras are running well within typical wear patterns, and the minimal failure rate of 0.21 per vehicle underscores how little goes wrong mechanically. The 1.6 advisories per vehicle are mostly minor maintenance items rather than structural concerns—if you're shopping used, prioritise a pre-purchase inspection on the hybrid electrical components, but this model's track record suggests you're buying into one of the more dependable compact SUVs on the market.
What to check before buying a 2020 Suzuki Vitara Sz5 Boosterjet MHEV
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.
