Actually Lexus did it, That is what has me concerned. The attitude of "oh well" guess you can replace the whole shroud (at my cost). This is a simple little plastic cap that, my guess, is that they outsource for the part and it has been made wrong. Now how many of these do you think they replace in a year? 10 maybe, so my voice alone is not getting anyone to look into it. In the mean time I have tape on the bottle. I sure wish someone knew where I could get the replacement so I could get past this. Thanx
