Service bulletin 09-002-15

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

Knocking Noise From Engine After Sitting Overnight This bulletin involves evaluating the engine for cold start knocking noise typically after an overnight cold soak. Some engines during this build period may have been built with incorrect piston wrist pins. The wrist pins will cause an audible knocking noise upon start up. The knocking noise will typically reduce after approximately 30 minutes of idle time. Engine replacement will be required. Some customers may comment they hear an audible knocking noise coming form the engine after start up for approximately 30 minutes. This only occurs after cold start when the vehicle has been sitting over night.
