What owners reported
Source: NHTSA complaint databaseOwners of the 17 model years this bulletin names have filed 8 complaints with NHTSA since 2015. 7 of them name Electrical System, Back Over Prevention, Forward Collision Avoidance — 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Bentley 2064648/6 a recall?

Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
