Do you think the ceramic coating could have hindered materials compliance ? Seen the microfiber clothes after ceramic gets applied and it turns rock hard. Wondering if ceramic on the seats may not be good long run ? Thought ?Tesla Service said it's common but after I explained to them the car has less than 4k miles and ceramic coated since day one by professional shop and weekly detailed, then they offer steam cleaning at service center to see if that work (FREE). They don't think its color transfer or stain, more of "common wear & tear "
