I have had my car for 1.5 years now and I just noticed a new, annoying rattling under the passenger seat. I hear it when I'm going going any faster than 5mph and then go over any small bump/crack. It sound like metal on plastic but I cannot pinpoint where it is coming from. Anyone have similar problems?

 

while the problem hasn't been solved per se. an existing thread is easily searchable: https://www.scionlife.com/forums/sho...ttle+passenger
