Should I check the MOT history before buying a 2021 Suzuki Sx4 S Cross Sz4 B Jet MHEV?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Suzuki Sx4 S Cross Sz4 B Jet MHEV?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Moderate sample. 347 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2021 SX4 S-CROSS is notably reliable, with a 91.1% first-time pass rate well above the UK average of 80%, and only 3.5% of vehicles ever recording a dangerous defect—a low concern for buyers. The hybrid powertrain shows no weak spots, maintaining the same 91.2% pass rate across the sample.

At under 32,000 miles on average for a three-year-old model, these cars are running light mileage, which explains the minimal failure rate of just 0.21 per vehicle. The typical advisory count of 1.4 per car suggests minor wear items rather than structural issues, so focus your pre-purchase inspection on suspension and brake fluid condition, where most advisories cluster on this generation.

The 2021 Suzuki Sx4 S Cross Sz4 B Jet MHEV passes its MOT first time more often than most UK vehicles (93.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
