# Service campaign RRA09202605

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.

## NHTSA's summary

A small number of Rolls\-Royce Phantom \(RR11/RR12\), Ghost \(RR21/RR22\), and Cullinan \(RR31\) vehicles have been identified as having a potential software issue concerning the remote services, with vehicles fitted with an ATM\-01 telematics control unit. As a result, vehicle remote services such as vehicle status may operate with a delay or not function completely. The problem has been rectified with vehicle software version 26\-03\-540 \(RR21\-26\-03\-540 for RR21/RR22 and Sl5A\-26\-03\-540 for RRll, RR12, RR31\), which is included in ISTA 4.58.4x.
