Known faults for Bentley Bentley Bentayga
Our database tracks 3 specific mechanical faults and recurring failure patterns identified across UK MOT testing stations for this generation.
MOT Roadworthiness: Good
This rating reflects historical MOT pass rates and recurring advisory wear patterns from official DVSA test logs. Note that roadworthiness does not verify outstanding finance, insurance write-offs, or stolen records.

Our Verdict
This 2017 Bentley Bentayga shows mixed reliability signals. While recent MOTs are clean, a 2024 failure and recurring brake wear raise concerns that require careful inspection before purchase.
Prioritize a full brake system inspection, particularly front discs and pads which showed wear in 2026. Verify registration plate compliance and parking brake functionality. Check service history for any missed maintenance, as Bentley's complex systems require strict upkeep. Negotiate based on the 2024 MOT failure and brake wear, which may indicate neglected servicing. Be cautious of hidden costs from luxury vehicle repairs.
The 5.9L petrol engine will have poor fuel economy (estimated 20-25 mpg), placing it in a high tax band (£1,100/year for 2026-27). Insurance groups for Bentleys are typically 50+ (very high premiums). Major maintenance like brake replacements could cost £1,000+ per axle. Annual running costs are estimated at £3,000-£4,000 including fuel, tax, and insurance.
Focus on brake components: measure disc thickness (minimum 28mm for front discs) and check pad wear. Inspect registration plates for compliance with current regulations. Test parking brake operation and adjust if necessary. Check for fluid leaks around the engine and transmission. Verify that all luxury features (climate control, infotainment) function correctly. Review service records for major work like timing belt replacement (recommended at 60,000 miles).
The vehicle has a mostly clean MOT history since 2023, but a 2024 failure for non-compliant registration plates and parking brake issues highlights potential maintenance risks. Brake components show gradual wear (front discs/ pads at 68,707 miles), and the 5.9L petrol engine is likely to have high running costs. Mileage of 68,707 miles (6,870 annual average) is below typical usage for a 9-year-old luxury SUV.
No aggregate MOT data available for the Bentley Bentayga, but luxury vehicles of this era typically require frequent maintenance for complex systems.

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.
- 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.
