# Service bulletins for the 2024 Rolls\-Royce Cullinan

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

4 bulletins from NHTSA, as of 2026-10-19.

- [RRA08202502](/bulletins/11022849.md), 2025-09-05, Service campaign: ELECTRICAL SYSTEM. A small number of Rolls\-Royce Cullinan \(RR31\) vehicles have been identified as having a potential issue concerning the key recognition. Due to a software error, the vehicle key may not be reliably recognized inside the trunk \(boot\) of the vehicle. This may potentially allow the vehicle to be locked while the key is in the trunk.
- [RRA01202501](/bulletins/11013536.md), 2025-02-04, Service bulletin: STRUCTURE:BODY. The tread plate should be gently pried up using an appropriate plastic wedge tool, and then the ribbon cable connector released.
- [RRA12202405](/bulletins/11012110.md), 2025-01-02, Service campaign: ELECTRICAL SYSTEM. A small number of Rolls\-Royce Phantom \(RRll/RR12\), Ghost \(RR21/RR22\), Spectre \(RR25\), and Cullinan \(RR31\) vehicles have been identified as having a potential software issue concerning the personal e\-SI M profile. As a result, vehicle telephone and Wireless Area Network \(WLAN\) hotspot functions via the personal e\-SIM may operate with a delay or not operate sporadically. The problem has been rectified with vehicle software version 24\-77\-540 \(RR21\-24\-11\-540 for RR21/RR22, RR25 and SlSA\-24\-11\-540 for RR11/RR12, RR31\), which is included in 1ST A version 4.50.4x.
