Summary

While the 2020 Bentley Mulsanne is a remarkable vehicle, it is not immune to some common issues. The engine intake manifold and turbocharger actuator malfunctions can lead to decreased performance, while electrical problems such as central control module failure can be costly to fix. The transmission shifting hesitation can be resolved through a software update, while interior issues like in-car entertainment system glitches and climate control malfunctions are relatively minor. Overall, the severity and cost of the issues are not significant considering the high price tag of the Mulsanne, but they do represent potential concerns for potential buyers.
