Sounds like she spilled it. Too much rain in paradise. The ac drain is clogged too. Seal is broken so water washing gets i side. Based in ur description, all applies to your case. And she definitely spilled it.

Oh no this is so terrible, hope you got it resolved, covered...I am also very disheartened by my Lexus..first the dashboard melted, turned to oil and mush...turns out this is common and a known problem, there was a recall that I 'missed' (bought it used) IMO If I put a luxury car on the market and it had parts that turn to goo...there would not be a time limit to fix it, I would honor the fact that dashboards should remain dashboards, and not a pile of oil, which by the is unhealthy, and it is extremely6 reflective, causing a glare on the windshield making it impossible to drive safely. Ive had it covered with an aftermarket ugly thing it is embarrassing. Also the windows- when I roll up and down, the goo gets on them too, from the door seals or somewhere in door panels.. it always looks a mess, have to use "goof off" every time someone uses my windows. Now, Im dealing the soaking wet floorboards, it is ridiculous I have never had so many 'factory' failing horrible issues with a car, Have had Cadillacs, Explorers, Maximas, lots and lots of cars and nothing close to this. Sorry to vent on your post, I am just commiserating with you.
