Service bulletin 20504

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

The connecting rod bushing over time may develop cracks or lose chunks of material which could lead to connecting rod engine failure. Connecting rod failure in some cases can result in engine shutdown with minimal warning. A stalled vehicle in or near the roadway can increase the risk of a vehicle crash.
