white splotches throughout my 2023 car (purchased in December) appeared during first heat wave with humidity in June. They detailed it out--figured it was sunscreen--lol--(I never sit in the back seats and all over them.) I think it is the oils from the leather seeping out. Would this be harmful if not just an eyesore? Subaru of America is sticking to the story it must be something I am doing wrong???? I just want it tested so I know it isn't toxic; then I'll deal with the cosmetic issue. Anyone ever hear of this?
