Question about lexus

[Al_335i]

Im buying a lexus soon, and i cant seem to find any answers, So heres my question, I heard the lexus is250, has been having problems with oil being low, I was wondering if thats an issue with the current models, or the gen before the current models?

Im thinking about buying a 2015 Lexus is250, i just don't want any problems with my oils always being low in like 2k miles. I know about the carbon build up, but i'm not worried about that since I own a bmw 335, and its known for all it problems and carbon build ups.
