2019 Bentley Bentayga — MOT failures & pass rate
Across 1,334 MOT tests, the 2019 Bentley Bentayga recorded a 96.5% pass rate. Large SUVs of a similar age fail 9.8% of the time, so this is 6.2pp better than the group it competes with. Failures cluster in tyres, emissions & environmental and other defects.
What the MOT record shows
No single area dominates — tyres (1.9%) and emissions & environmental (1.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are registration plates, catalyst emissions and headlamp aim — registration plates alone was recorded 17 times.
Mileage matters less than usual here: the 2019 Bentayga fails 3.2% of the time in the 0-30k band and 6.1% at 60-90k, a spread of only 2.9 points.
Tyres is the most common advisory, noted on 9.7% of tests — work that passed today but is likely due soon.

What to check before buying a 2019 Bentayga
The failure pattern for this year is specific enough to inspect against: tyres accounted for 1.9% of tests. Start there.
- Tyres (1.9% 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.
- Emissions & environmental (1.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Other defects (0.8% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
