2019 Jaguar XJ — MOT failures & pass rate
Across 1,857 MOT tests, the 2019 Jaguar XJ recorded a 92.2% pass rate. Executive cars of a similar age fail 10.2% of the time, so this is 2.4pp better than the group it competes with. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
One area stands out: tyres, recorded in 5.0% of tests against 1.5% for the next-worst category.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 33 times.
Mileage matters less than usual here: the 2019 XJ fails 5.7% of the time in the 0-30k band and 9.0% at 60-90k, a spread of only 3.3 points.
Tyres is the most common advisory, noted on 23.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 8.5% in 2021 to 6.9% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2019 XJ
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.0% of tests. Start there.
- Tyres (5.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (1.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (1.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
