Does sound ridiculous, but it's literally a hole under the seat that small objects can easily fall into and rattle around. That's what the complaint is, it looks like there should be some sort of seal around it but it's just foam and carpet.
ive lost the lid off a usb pen drive in my car, fell down the side of the drivers seat, i was parked at the time so immediately stuck my hand down there, nothing so opened the door and looked around, still haven’t found it and I checked everywhere c
