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.

The 2021 Fiat 500 Star MHEV passes its MOT first time more often than most UK vehicles (91.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 91.8% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,081 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
