# Service bulletin 0051440500

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.

## Other bulletins for the same vehicles and component

- [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.
- [A07202207UC](/bulletins/10218354.md), 2022-08-22, Service bulletin: ELECTRICAL SYSTEM. The affected vehicles have been identified as having a potential issue with an incorrect option code added to the build specification. This resulted in the incorrect coding of the Advanced Telematics Module \(ATM\), which led to the Connected Services not operating correctly or ATM not being able to update.
- [A07202206](/bulletins/10218353.md), 2022-08-22, Service bulletin: ELECTRICAL SYSTEM. The vehicles identified may potentially not transfer incoming voice audio during a telematics call due to the 3G network deactivation in the United States. Therefore, this will affect all Connected Services voice audio in an Emergency call \(E\-call\), Concierge call and Roadside assist calls.
