I have a 06 tl base AT w 87k miles. I have only noticed this issue once beofre and It was when I cleaned my dash and interoir for that matter. Yesterday I detailed my whole car and cleaned the dash with windex. Before this discoloration came up when I cleaned my dash and some how went away. I noticed it but I didn't think much of it since it went away and wasn't that noticably by the naked eye. This time however it is very visable.

I guess my questions are:

1 has this happen to anyone before?
2 what is the outline of? Airbag?
3 is my dash gonna crack
4 what do you think acura will do about?


Here's the pic, im posting from my droid so bare with me

 

 

wait why are you using windex on plastic? does the windex you have contain ammonia as well? That cant be too good for the plastic.

I would go buy something like (< Link)and wipe down the vinyl parts asap. I saw the honda dealer parts counter sold this.

picture's broken, but if there's a rectangle outline on the passenger side, yes it is the airbag, and it is somewhat normal to see a slight depression where it is.
