Should I check the MOT history before buying a 2012 Jaguar Xj?

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.

What corrosion should I look for when inspecting a 2012 Jaguar Xj?

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.

How are tyres and brakes typically on a 2012 Jaguar Xj?

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 2012 Jaguar XJ passes its MOT slightly more often than average UK cars (85.6% versus 80%), which is encouraging, but a serious concern looms: 42.5% of these vehicles have recorded dangerous defects at some point. This is well above acceptable levels and suggests buyers should expect to encounter serious safety or emissions issues during ownership.

At 67,000 miles median mileage for a 12-year-old car, these XJs have been driven sensibly, yet they're racking up an average of 1.86 failures and 12 advisories per test—pointing to ageing electrics, suspension wear, and fluid leaks rather than catastrophic mechanical breakdown. Before buying, get a full pre-purchase inspection by a Jaguar specialist and budget for repair costs, as the combination of high advisory rates and that dangerous defect history suggests this luxury saloon can become expensive to keep safe and legal.

The 2012 Jaguar Xj has a decent first-time pass rate (85.6%), 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 85.6% 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 12 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 1,168 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.
