Service bulletin TSB110277-021420
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 explains that a new cylinder block and cylinder liner were introduced in production and service. The new cylinder block was designed to be backward compatable for repairs; however, the cylinder liner design is not cross-compatable between cylinder block designs. This bulletin explains how to address compatibility between the blocks and liners. This is an update to a previously submitted communication.
