Owners/service Manual problems of the 2012 Toyota Camry Hybrid

Toyota fails to disclose that sunroof has drains designed to discharge water from the top of the vehicle. If one of these drains get clogged (and could happen very easy) water gets inside the vehicle. Water infiltration can start with a very slow amount so the issue is not discovered immediately because underneath the carpet is a material that absorbs this water. Mold can be developed, as well as electrical malfunctions during driving. My spouse accused breathing issues and psoriasis and we discovered that our vehicle is getting rain water inside. Could be for months or even years, as well as since we purchased it - there is not way to assume or to notice how much water you have in which time because you discover it when is too late. Toyota refuses to assume any responsibility for the damage, claiming that are not responsible for damages caused by outside elements. But in the Toyota owner manual this drain is not disclosed to the customer, so it could take a periodic check. Also lustine Toyota from woodbridge va where we service the car at every six months since we purchased the vehicle, does not have any recommendation, written or not, about these drains but instead can diagnose very quick that the water in the carpet comes from clogged drains. How come that Toyota is well aware about the issue but is not raising any awareness about it, so the customer can be prepared in advance instead of having the vehicle full with water and to pose dangers while operating the vehicle for himself and others around? Toyota needs to be held responsible like any other manufacturers are (see ww, Chrysler, Volvo) for failure to disclose important car features. We will need to get the vehicle back to the dealer and the issue to be corrected on their expense but the Toyota customer service, represented by mrs. Kristen, refuses. Our case number was 1802171412 please help.
