2017 Jaguar XF — MOT failures & pass rate
The 2017 Jaguar XF passed 89.8% of its 39,399 recorded MOT tests. Executive cars of a similar age fail 11.6% of the time, so this is 1.3pp better than the group it competes with. Failures cluster in tyres, brakes and visibility.
What the MOT record shows
No single area dominates — tyres (5.3%) and brakes (2.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and brake pads — tread depth alone was recorded 1,287 times.
Mileage matters less than usual here: the 2017 XF fails 7.0% of the time in the 0-30k band and 8.0% at 150k+, a spread of only 1.0 points.
The petrol cars hold up better: 8.2% fail against 10.4% for diesel, a 2.2-point gap across 39,399 tests.
Tyres is the most common advisory, noted on 22.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.0% of tests failed in 2021 against 10.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 XF
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.3% of tests. Start there.
- Tyres (5.3% 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.
- Brakes (2.9% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (2.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
