There is a repetitive problem with mold and AC leaks with the Scion xD. I’m having breathing problems and I feel sick. Geico and Toyota have discovered mold in my vehicle. It is actually visible but I have no idea how long there has been a leak or how long I have been breathing in mold. The AC line is under the carpet with no protective barrier which is an ideal environment for mold to grow. When I looked up a way to fix the issue several videos came up with many others who have the same issue which means it is not a maintenance issue it is a defect that has never been recalled. Toyota has serviced my vehicle for years and never brought up this issue. I didn’t notice a problem until there was a pool of water in my car and mold growing on my seats. When I brought it in to Toyota they told me what the problem was instantly. They’ve seen it plenty of times before. When I looked online I see several owners of ScionxD made in different years with the same problem. How long has my car had this leak and how long have I been breathing in mold before it was visible to my eye? Seeing as there are so many Toyota Scion drivers/owners with this issue I am reporting it to NHTSA and calling Toyota Scion Corporate Headquarters. Corporate headquarters did nothing about the issue even after I expressed my concern for the children in danger of being exposed to mold who ride in these cars everyday. I am still breathing heavy and suffering from headaches. The Toyota dealership said it would cost $4400 to fix the entire issue. Why place a tube under a carpet without protection? I wish I was informed of this earlier.
