Should I check the MOT history before buying a 2015 Porsche Cayenne?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

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.

The 2015 Porsche Cayenne has a decent first-time pass rate (89.5%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 89.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 6.4 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 2,676 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

2015 Porsche Cayenne — Still on the Road

Almost all 2015 Porsche Cayennes are still on the road.

Strong survival — 2,229 vehicles still getting MOTs in 2025, 90% of the peak.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2018–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
