I have 2014 suzuki swift when I bought it there was no rust in the trunk and Its been an year now and i noticed that inside the trunk, under the stupney there is rust and moisture. Trunk door is closed and sealed. I dont know where the water is coming inside the stupney area which is also covered with foamed hard board and other stuff was on the board like top cover etc. nothing is wet.
I am sure the water is rain water as I dried the area before and yesterday night there was rain and in the morning I checked the trunk and again there was a literally water standing inside it while all other stuff inside the trunk was dry. Where this water coming from and how to fix it. Does anyone faced the same issue?
