Porsche Cayenne (2015)
2015 Porsche Cayenne
CarHunch analysed 2,676 real MOT records for the 2015 Porsche Cayenne. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Cayenne passes its MOT at 89.4%, well above the UK average of 80%, which is genuinely reassuring—but the warning sign is that 25.6% of these vehicles have recorded a dangerous defect at some point, significantly higher than typical and a real concern for prospective buyers. Diesel variants slightly underperform their petrol counterparts (89.4% vs 89.9%), though the difference is marginal across all three fuel types.
At a median mileage of 57,309 miles for a nine-year-old car, these Cayennes are running relatively low, suggesting careful ownership by most. The average of 0.97 failures per vehicle is reasonable, but the 6.4 advisories per car hint at the wear and maintenance costs inherent to a complex German SUV—check service history and have a pre-purchase inspection focus on suspension, electrics, and brake systems where warnings cluster.
What to check before buying a 2015 Porsche Cayenne
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.
- ⚠️ 25.6% 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.
