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.

We have limited data for the 2021 Suzuki Sx4 S Cross Sz T B Jet MHEV A — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
