Service bulletin TSB190058-080820

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 Technical Service Bulletin describes the verification and resolution of an oil leak between the cylinder head and cylinder block on the intake side of the engine as caused by an excessive compression set of silicone oil grommets leading to an external oil leak. This is an update to a previously submitted communication.
