Service bulletin 18-056-15
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.

A small number of customers may experience a clicking type noise coming from the engine area while driving. The concern may be caused by rapid activation and deactivation of the auxiliary water pump relay. This software update will improve the activation and deactivation cycle of the auxiliary water pump relay.
