This 2021 SX4 S-CROSS is a genuinely reliable proposition: 93.7% of these cars pass their MOT first time, significantly outpacing the UK average of 80%, and only 3.1% have ever picked up a dangerous defect. The hybrid powertrain appears to be delivering on durability, with no meaningful reliability split to worry about across the sample of 126 vehicles tested.

At just over 24,000 miles median mileage, these cars are relatively lightly used for their age, which helps explain the strong pass rate, but the real reassurance comes from averaging only 0.2 failures per vehicle and 1.0 advisory per vehicle—suggesting the SX4 S-CROSS is mechanically straightforward and not throwing up surprise issues. If you're considering one, check the service history carefully to ensure the hybrid system has been looked after, but the MOT data suggests this model is well worth shortlisting.
