Bentley filed this with NHTSA as a service bulletin dated Oct 11, 2023, received Nov 6, 2023, about the power train. It names 41 model years (2016–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 32 model years this bulletin names have filed 20 complaints with NHTSA since 2015. 3 of them name Steering — 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.
On December 2, 2025 I was driving on interstate 26, and warning lights came on, at the same time steering locked up and was I unable to steer. I did manage to slowly leave right lane, about 200 yards, and enter shoulder. I turned off and restarted many times and finally the steering unlocked. In Sept. car was brought to dealer.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Bentley 2056407.5 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 2056407.5 repair free?
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.
Which vehicles does 2056407.5 cover?
The manufacturer filed it against 41 model years: 2024 Bentley Bentayga, 2023 Bentley Bentayga, 2022 Bentley Bentayga, 2021 Bentley Bentayga, 2020 Bentley Bentayga, 2019 Bentley Bentayga and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
