Vauxhall Astra (2015)
2015 Vauxhall Astra
CarHunch analysed 50,571 real MOT records for the 2015 Vauxhall Astra. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Vauxhall Astra passes its MOT at 82%, slightly above the UK average, but nearly 41% of these cars have recorded a dangerous defect at some point—a notably high figure that suggests wear-related safety issues are common by this age. Petrol versions hold a small advantage over diesels (82.5% vs 81.0% pass rate), though the gap is marginal.
At nearly 48,000 miles median mileage, these Astras have covered a reasonable distance for their age, yet they're still averaging 1.87 failures per MOT—indicating that mechanical problems accumulate steadily. The high advisory count of 10.2 per vehicle reflects typical age-related wear rather than catastrophic faults, but when shopping for one, prioritise a full service history and get a pre-purchase inspection focused on suspension, brakes, and emissions systems, where these cars commonly fail.
What to check before buying a 2015 Vauxhall Astra
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.
- ⚠️ 40.8% 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.
