2023 Ford Fiesta ST Line X Ed T MHEV A

CarHunch analysed 115 real MOT records for the 2023 Ford Fiesta ST Line X Ed T MHEV A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2023 Fiesta is a significant red flag: only 34% pass MOT on their first attempt, less than half the UK average of 80%, and virtually all vehicles in this cohort (99%) have recorded a dangerous defect at some point. For a car barely a year old with average mileage around 17,500 miles, this failure rate is alarmingly high and suggests systemic build or design issues rather than wear-and-tear problems.

The low failure count (0.05 per vehicle) and advisory rate (0.1 per vehicle) actually underscore the real problem—these cars aren't failing on minor niggles, they're hitting dangerous defects that need fixing before they're legal to drive. If you're considering this model, obtain the full MOT history before purchase and have an independent pre-buy inspection focus on whatever defects are appearing repeatedly across the cohort.

What to check before buying a 2023 Ford Fiesta ST Line X Ed T MHEV A

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.
