Vauxhall Grandland X Sport Nav T D Ss (2018)
2018 Vauxhall Grandland X Sport Nav T D Ss
CarHunch analysed 114 real MOT records for the 2018 Vauxhall Grandland X Sport Nav T D Ss. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 Vauxhall Grandland X Sport Nav T D SS passes its MOT first time in just 69.2% of cases, significantly below the UK average of 80%, which suggests this diesel model has genuine reliability concerns worth investigating before purchase. The good news is that dangerous defects are absent from this dataset and advisories are virtually non-existent, so failures tend to be manageable rather than safety-critical.
At 58,000 miles median mileage for a six-year-old car, these vehicles are running close to expectations, yet the 0.14 average failures per vehicle indicates a pattern of recurring issues rather than isolated problems. Before committing to one, get a pre-purchase inspection focused on the diesel engine and gearbox, and factor in a higher-than-average likelihood of MOT work in your first year of ownership.
What to check before buying a 2018 Vauxhall Grandland X Sport Nav T D Ss
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.
