What owners reported
Source: NHTSA complaint databaseOwners of the 24 model years this bulletin names have filed 20 complaints with NHTSA since 2015. 6 of them name Electrical System, Visibility/Wiper — 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 bad design of the Bentley Bentayga ventilation system at the front causes the screen to steam up all the time in humid weather making it very hard to see out the front window. You clean it and it is steamed again in 5 seconds. I have nearly hit a pedestrian because of the bad visibility on a relatively humid virginia day.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.
