Maybe this has been covered before but last winter my 2007 RX400h developed a severe interior water leak, spreading from the inside driver footwell to the rear foot wells. Videos on YouTube can be found showing this issue. I also reported it to Lexus main dealer during a recent air con recharge but they were oblivious to the issue. No such problems this year yet but with winter soon to take hold I’m wondering if my carpets will once again be sodden. Anybody else experienced this and had it investigated/sorted? Cheers
