2017 Toyota Yaris

CarHunch analysed 27,235 real MOT records for the 2017 Toyota Yaris. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2017 Toyota Yaris is a reliable performer with an 88.9% first-time pass rate that comfortably beats the UK average of 80%, and petrol variants edge slightly ahead at 89.3% compared to hybrids at 88.4%. One in six of these cars (16%) have recorded a dangerous defect at some point, which is a notable concern for buyers—worth a pre-purchase inspection.

These cars are running low mileage for their age, with a median of just under 30,000 miles, suggesting many are urban runarounds that haven't been thrashed. The average of 0.89 failures per vehicle is reassuring, though 5.6 advisories per car points to minor wear creeping in—so factor in routine maintenance costs before you buy, and always get a full MOT history check.

What to check before buying a 2017 Toyota Yaris

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.
