I have heard of some with trouble with a "pop" noise occurring in their drivers seat. I think I´d take the "pop" over the sound my passenger seat makes with NOONE in it. Granted I drive bumpy roads but the rattling from day one is driving me nuts. It sounds like it is loose in the tracks. Unfortunatley I am in Puerto Vallarta Mexico so the local dealer can´t do shiddles about it. Any ideas amigos?
