2021 Fiat 500 Lounge MHEV
CarHunch analysed 3,394 real MOT records for the 2021 Fiat 500 Lounge MHEV. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 FIAT 500 Lounge MHEV is a notably reliable first-time MOT performer, passing at 91.2% against the UK average of 80%—a 11-point margin that puts it in the top tier. The dangerous defect rate of 9.9% is reassuringly low, so structural and safety issues are uncommon in this cohort.
At 20,256 miles median, these cars are still relatively young and lightly used, which explains the low failure count of 0.25 per vehicle on average. The 1.3 advisories per car suggest minor wear items (tyres, wipers, trim) rather than systemic problems, so budget for routine servicing but don't expect surprise repairs; when shopping, prioritise full service history and check tyre condition yourself to avoid the most common advisory flags.
What to check before buying a 2021 Fiat 500 Lounge 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.
