Service bulletin PIP5570

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 Preliminary information communicates to the dealer a condition where a tick noise may be present inside a vehicle while driving. This may be the result of a deformed or improperly seated steering shaft seal allowing engine compartment sounds into the vehicle. Dealers are instructed to replace or reinstall the boot as needed and are informed the condition is being reviewed by engineering.
