Jaguar Xf (2018)
2018 Jaguar Xf
CarHunch analysed 5,978 real MOT records for the 2018 Jaguar Xf. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 Jaguar XF passes its MOT first time at 87.8%, comfortably above the UK average of 80%, which is genuinely reassuring for a six-year-old premium saloon. However, nearly one in four of these vehicles (24.6%) have recorded a dangerous defect at some point, which is a meaningful concern for buyers and suggests careful inspection of brakes and steering components is essential.
These cars are running at a modest 42,700 miles on average, so you're typically looking at low-mileage examples that should have some life left in them. The average 0.68 failures per vehicle is respectable, though the 5.8 advisories per test hint at ageing seals and minor wear items that are worth factoring into your ownership budget—get a pre-purchase inspection that specifically addresses suspension and trim wear on any XF you're considering.
Petrol vs Diesel
Pass rate difference of 2.7 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2018 Jaguar Xf
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.
- ⚠️ 24.6% 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.
