Vauxhall Astra (2017)
2017 Vauxhall Astra
CarHunch analysed 47,634 real MOT records for the 2017 Vauxhall Astra. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2017 Vauxhall Astra passes its MOT significantly more often than the UK average—87.1% versus 80%—which is a solid result, though the fact that 30.5% of these vehicles have recorded a dangerous defect is a red flag worth investigating on any used example you're considering. Petrol versions are notably more reliable than diesels, with an 88.3% pass rate compared to 84.7%, suggesting the petrol engine is the better bet for longevity.
At a median mileage of 39,349 miles for a seven-year-old car, these Astras are running at typical wear levels, and the average of 1.05 failures per vehicle indicates most don't need major work when they fail. With 7.3 advisories recorded per car on average, expect minor fixes like worn brake pads or tired suspension components rather than structural problems—but always get a pre-purchase inspection to confirm no dangerous defects are lurking in the specific car you're buying.
Petrol vs Diesel
Pass rate difference of 3.6 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2017 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.
- ⚠️ 30.5% 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.
