Toyota Yaris (2020)
2020 Toyota Yaris
CarHunch analysed 14,721 real MOT records for the 2020 Toyota Yaris. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Toyota Yaris is unusually reliable, with a 91% first-time MOT pass rate that sits well above the UK average of 80%, and only 6.6% of cars ever developing a dangerous defect—a genuinely low concern rate for the market. Both the hybrid (90.5%) and petrol (91.8%) versions perform strongly, so fuel type won't be a deciding reliability factor here.
At an average mileage of 23,670 miles for a 2020 model, these cars have been driven moderately and are still early in their lives—which explains the low failure rate of 0.36 per vehicle. When issues do crop up, they're typically minor advisories (averaging 2.0 per car) rather than failures, so budget for preventative maintenance but don't expect costly surprises; a pre-purchase inspection will catch anything unusual before you commit.
What to check before buying a 2020 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.
