Mini Cooper S (2023)
2023 Mini Cooper S
CarHunch analysed 657 real MOT records for the 2023 Mini Cooper S. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2023 MINI Cooper S is a strikingly reliable newcomer, with a 96.6% first-time pass rate that far exceeds the UK average of 80%—and dangerous defects are rare at just 1.8% of vehicles, so safety isn't a concern here. Both the petrol and hybrid-electric variants perform nearly identically, with pass rates of 96.5% and 96.8% respectively, giving you confidence regardless of which powertrain you choose.
At a median mileage of just 15,293 miles, these are still very young cars, and that low mileage context explains why failures are nearly non-existent (0.05 per vehicle on average). What matters for a buyer is that the 0.2 advisories per vehicle suggest minimal wear—if you're shopping used, prioritise a full service history and have a pre-purchase inspection focus on the electrical systems, since hybrid components can be expensive to repair.
What to check before buying a 2023 Mini Cooper S
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.
