Service bulletin LI47.10-P-079166
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
Complaint A pulsating knocking noise (e.g. clattering) can be heard underneath the bench seat, particularly in the case of a full tank (1/1 fill level). Cause The vibrating air column of the purge flow volume triggers the fill limit vent valve (FLVV) to open and close repeatedly when the fuel tank is full. Remedy By reducing the fuel quantity by around 5 liters, the noise can no longer be heard. In isolated cases, the noise can also be amplified by a fuel tank installed under stress and therefore lines adjacent to the body-in-white (above the fuel tank). In this case, the installation position of the fuel tank and the contact surfaces to the body-in-white must be checked. To do so, loosen the fuel tank and refasten it. Please do not replace component parts such as the fuel tank, activated charcoal canister, purge valve or delivery module, as this does not provide a remedy. If a similar noise can be heard with a tank fill level of, for example, 3/4 or 1/4 and not with a full tank (1/1), there is a different issue.
