Toyota Yaris (2018)
2018 Toyota Yaris
CarHunch analysed 28,340 real MOT records for the 2018 Toyota Yaris. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 Toyota Yaris is a genuinely reliable car, with an 88.5% first-time pass rate that sits well above the UK average of 80%. Only 11.9% of vehicles have ever recorded a dangerous defect, which is reassuringly low and suggests structural safety isn't a concern for this cohort.
At 27,236 miles median mileage, these cars have been used gently for their age, and the 0.68 average failures per vehicle confirms they're holding up well. Petrol models edge out hybrids slightly (89.3% versus 87.9% pass rates), but both are solid; focus your used car search on full service history rather than fuel type, and you'll have a dependable small car that won't ambush you with repair bills.
What to check before buying a 2018 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.
