# Service bulletins for the 2025 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.

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

- [B066\-25](/bulletins/11025855.md), 2025-12-01, Other: ENGINE. Expansion Tank Return
- [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.
