Fiat 500x (2021)
2021 Fiat 500x
CarHunch analysed 863 real MOT records for the 2021 Fiat 500x. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 FIAT 500X is a genuinely reliable performer, with a 92.4% first-time MOT pass rate that sits well above the UK average of 80%. Dangerous defects have appeared in only 7% of vehicles tested, which is reassuringly low and well below the threshold that would suggest systemic safety concerns.
These cars are running at modest mileage—a median of 29,595 miles for three-year-old examples—so you're looking at relatively lightly used stock in the market. With an average of just 0.25 failures and 1.4 advisories per vehicle, the 500X shows up as straightforward to maintain: when you do visit the garage, expect minor wear items rather than structural problems, so don't hesitate to have a pre-purchase inspection done on any example you're seriously considering.
What to check before buying a 2021 Fiat 500x
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.
