This Swift is a genuinely reliable performer: 93.5% of vehicles pass their MOT first time, well ahead of the UK average of 80%, and only 3.7% have ever recorded a dangerous defect—a reassuring figure for a potential buyer. The hybrid powertrain appears to be working well, with virtually no fuel-type variation to worry about.

At just under 24,000 miles on average, these cars are still young and lightly used, which explains the low failure rate of 0.18 per vehicle. The real takeaway is in the advisories: 1.3 per car is modest, suggesting routine wear rather than systemic issues, so when shopping, focus on full service history and recent brake/tyre inspections rather than sweating structural concerns.

The 2021 Suzuki Swift Sz L Dualjet MHEV passes its MOT first time more often than most UK vehicles (94.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
