2016 Bentley Bentayga — MOT failures & pass rate
The 2016 Bentley Bentayga passed 95.4% of its 2,024 recorded MOT tests. Against large SUVs of a similar age (12.4% fail rate), the 2016 Bentayga comes out 7.8pp better. Failures cluster in tyres, lighting & signalling and other defects.
What the MOT record shows
No single area dominates — tyres (3.2%) and lighting & signalling (0.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are registration plates, tread depth and headlamp aim — registration plates alone was recorded 23 times.
Mileage matters less than usual here: the 2016 Bentayga fails 4.5% of the time in the 0-30k band and 4.9% at 60-90k, a spread of only 0.4 points.
Advisories point at the next bill rather than this one: tyres was flagged on 12.5% of tests without failing them.

On a 2016 Bentayga, tyres is what the MOT record says goes wrong most — it appeared in 3.2% of tests. Check these areas before you commit.
- Tyres (3.2% 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.
- Lighting & signalling (0.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Other defects (0.6% 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.
