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.
