I took my LC in for them to look at the rattle. I mentioned that it could be the coolant hose clamps being too close to the firewall. They fixed it but told me it wasn't those hose clamps. They said the vibration from the engine was making a high voltage cable (one of those orange ones) shake. Part of that cable then rattled against the metal sheathing of the fuel line, somewhere on the underside of the engine compartment. Regardless of the source, I'm very happy the noise is gone now.
