Lexus Is (2015)
2015 Lexus Is
CarHunch analysed 3,090 real MOT records for the 2015 Lexus Is. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Lexus IS is significantly more reliable than the UK average, with a 90.3% first-time pass rate versus 80%, though nearly 28% of these vehicles have recorded a dangerous defect at some point—a concern worth investigating during a pre-purchase inspection. Both the hybrid and petrol variants perform similarly well, with pass rates around 90%, so fuel type isn't a reliability differentiator here.
These cars are running at a sensible 55,000–62,000 miles for their age, and while they average less than one failure per test, the high advisory rate of 5.7 per vehicle suggests wear-and-tear items need regular attention. Check the MOT history carefully for patterns in those advisories, and budget for preventative maintenance on common wear items rather than expecting major structural problems.
What to check before buying a 2015 Lexus Is
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.
- ⚠️ 27.6% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
