No rattles in the boot for me, I did notice though when collecting the towing eyes that are installed front and rear for transportation, we’re put under the boot carpet by the Bose Subwoofer loose, and the 2 charging cables and bag were also loose in the boot. The luggage / dog net for was also loose in the boot. So could be a number of things. I rearranged all the items and put them under the carpet into there little compartments so no rattles or sounds coming from anywhere. In EV mode all you hear is the Electric Motor, that sounds like a Super Charger. Also the 12 Speaker Bose will eliminate any rattles or squeaks ?
