Service bulletin A1923392070349_1

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

This bulletin advises that a small amount of coolant loss is normal. Otherwise, clean and visually inspect the coolant system in the presence of a small leak to verify if a repair is needed, and then to repair a component if it is verified to have been leaking actively.
