An annoying clonking knocking noise has developed in my Jazz. Its a late 2008 EX (Japanese built). I've taken EVERYTHING out of the boot area, including the parcel shelf, to check where its coming from. Its a heavy metallic 'thonk' and seems to be in the rear seat or C-pillar area - on both sides of the car.
It seems to do it with the seats either in normal position, or magic seats up. But not when they are fully down. The car has to be travelling, but it doesn't seem to be affected by speed, braking, turning left or right, or if its cold or hot inside/out. It still does it if the seatbelts are done up or not. Nothing obvious seems to be loose, the plastic panels are not cracked or pinged out of shape, nor are the seatbelt or seat mountings undone. I'm worried its something to do with rear airbags, the seatbelt mechanism, or safety of the rear seat catch.
My car just randomly 'clonks' as I drive along. Its driving me nuts!
Before I take it down to Honda and ask them to check it out, has anyone else come across this problem?
