Our Verdict
Recommended for its low mileage and clean recent MOT, but inspect tires and windscreen for issues from the 2025 failure.
Prioritise checking the tires and windscreen for signs of the 2025 MOT failures. Verify service records to confirm repairs were completed. Negotiate based on the model’s luxury pricing and potential for higher maintenance costs. Be cautious of the vehicle’s age and lack of aggregate reliability data, which may impact long-term value.
Petrol fuel economy is likely poor given the 4.0L engine. Road tax for 2026 would be £155 annually (petrol, 2017+). Insurance groups for luxury vehicles like the Bentayga are typically high (estimate £1,200-£1,500 annually). Maintenance costs will exceed average due to premium parts and specialist servicing. Estimated annual running cost: £2,500-£3,000.
Focus on the offside rear tire and nearside front tire for structural integrity, as highlighted in the 2025 MOT. Check the front windscreen for cracks or damage that could affect visibility. Inspect the engine and transmission for signs of wear, as luxury vehicles often require meticulous maintenance. Verify that all MOT failures were fully resolved before purchase.
This 2020 Bentley Bentayga has low mileage (46,618 miles) for its age and a recent MOT pass. However, a 2025 MOT failure highlighted tire and windscreen issues. No aggregate reliability data is available for the model, but the vehicle’s history suggests manageable maintenance risks.
No aggregate MOT data exists for the Bentley Bentayga, making it difficult to assess broader reliability trends for this model.

AI Analysis
Historical fault & advisory patterns
Common Problems: BENTLEY BENTAYGA
Known issues reported by owners and MOT testers.
- Carbon Build-up (GDI Coking)(Moderate)
Direct injection leads to carbon deposits on intake valves, reducing performance and fuel economy.
- Fuel Leak Recall(Serious)
Early V8 models were subject to a recall for a potential fuel leak from the fuel line quick connector.
- Infotainment and Electrical Glitches(Moderate)
The Bentayga's complex electronics, including the infotainment touchscreen, parking sensors, and adaptive cruise control, are prone to software bugs and random reboots. Moisture ingress into wiring can cause cascading electrical failures.
