Rolls-Royce bulletin RR65522171
Rolls-Royce filed this with NHTSA as a service bulletin dated Apr 1, 2021, received May 24, 2021, about the engine and engine cooling — 2 documents under this number. It names 15 model years (2016–2021). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Rolls-Royce RR65522171 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 RR65522171 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 RR65522171 cover?
The manufacturer filed it against 15 model years: 2021 Rolls-Royce Cullinan, 2020 Rolls-Royce Cullinan, 2021 Rolls-Royce Ghost, 2020 Rolls-Royce Ghost, 2018 Rolls-Royce Ghost, 2017 Rolls-Royce Ghost and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
