Service bulletin 19LC05 - Dealer

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

Dealer Package: The involved vehicles are equipped with an engine oil cooling system. The oil cooling system could experience a small leak due to a manufacturing issue. If a vehicle is continuously operated with this condition, it may result in abnormal engine noise, illumination of the Malfunction Indicator Light (MIL), and an engine oil level low message. Over time, an oil pressure warning message may be displayed on the multi-information display and/or a buzzer may sound.
