2021 Fiat 500 Star MHEV
CarHunch analysed 1,081 real MOT records for the 2021 Fiat 500 Star MHEV. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 FIAT 500 STAR MHEV is a reliably built small car, with a 90.1% first-time MOT pass rate that comfortably beats the UK average of 80%. Only 11.7% of vehicles have ever suffered a dangerous defect, which is well below the threshold for genuine concern.
At just under 22,000 miles on average, these cars are still relatively young and lightly used, and the data bears that out—owners are averaging only 0.26 failures per vehicle and 1.4 advisories, suggesting the hybrid drivetrain is holding up well. If you're considering one, check the service history carefully and budget for any deferred maintenance, but this cohort shows no structural reliability red flags.
What to check before buying a 2021 Fiat 500 Star MHEV
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.
