Service bulletin L-TT-0184-15

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

TT: Some vehicles may experience an intermittenly "tick" or "rattle" noise when over uneven terrain. The noise is typically present when the front passenger seat is empty and will go away when the front passenger seat is removed from the vehicle. Closer investigation may find the noise emanating from the Passenger Side floor sheet metal near one of the spot welds in the floor underneath the front passenger seat.
