The Bentayga launched as the worlds first luxury SUV, featuring the 6.0 W12 engine. These early cars are the most affordable but carry the highest maintenance risk, particularly regarding carbon build-up on the direct-injection engine and expensive tyre costs.
Direct injection leads to carbon deposits on intake valves, reducing performance and fuel economy.
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.
