Toyota Unknown (2017)
2017 Toyota Unknown
CarHunch analysed 305 real MOT records for the 2017 Toyota Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2017 Toyota is a significant reliability concern: just 28.3% pass first time, compared to the UK average of 80%, and the median CarHunch score of 35 is well below acceptable. Only 2% have recorded dangerous defects, so safety isn't the primary worry—instead, these vehicles are prone to multiple minor issues that accumulate across tests.
The relatively low average mileage of 55,069 miles for a seven-year-old car suggests these haven't been thrashed, yet they're still failing repeatedly, pointing to design or maintenance problems rather than wear and tear. With 0.4 advisories per vehicle on average, prospective buyers should budget for ongoing repair costs and get a full pre-purchase inspection to identify what's actually wrong before committing.
What to check before buying a 2017 Toyota Unknown
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.
