Service bulletin RRA10202005

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.

RRA122022072023-01-30. Service bulletin. A Rolls-Royce Phantom (RR11/12), Ghost (RR21/22) and Cullinan (RR31) vehicles have been identified as having a potential issue concerning the 2 x coolant pipe connections at the cylinder head. The coolant pipe retaining clips (jubilee clips) may not have been fitted in the correct position, which could result in a coolant leak.

RRA022021032021-03-15. Service bulletin. A very small number of Rolls-Royce Cullinan (RR31) vehicles have been identified as having a potential issue concerning the engine earth connections. It could be possible that during the engine assembly, one of 16 earth connectors was not torqued to the required specification resulting in an inconsistent electric connection. If one of these connectors is not tightened correctly the following problems may occur: l) MIL light would be activated, 2) failure to start the engine, 3) long term - oil pressure sensor damage.
