What owners reported
Source: NHTSA complaint databaseOwners of the 25 model years this bulletin names have filed 20 complaints with NHTSA since 2015. 9 of them name Electrical System, Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
There’s sudden PDC fault arises, the vehicle’s all radar system is broken. Sometimes, the dashboard will be turned off during driving. WHEN PDC fault appears, the rear view camera when parking does not appear. Very dangerous while manipulating the car. This is a common issue in 2020 Bentley Flying Spur. I’ve done research with engineers.

The auto start on this Bentley bentagya most of the time does not work properly, but as I AM now over 12,000 miles it has started to cause the car to call at odd times. For example coming out of a parking space the car stalled leaving me half in and half out the space. It also stalled at a traffic light 3 days ago.
