I bought a brand new 2015 GS350 less than one year ago, now it has 3800 miles on it. I just found out the driver side front wheel touches the fender when I turn right half way. I reported to the dealer and the dealer is not surprised without solution at all, which surprised me!!
I checked another 2015 GS350 from the dealer, it has the same issue, you can see the front fender is shinning because of the scratches since that car has more miles on it.(18 inch wheel)
After comparing the passenger side front wheel, I found out the driver side wheel is 1 inch closer to the fender than the passenger side.
I reported to Lexus, it is a design defect for sure. you can imagine when winter comes, the snow on tires would chop the fender off.Please check your car to make sure you are not the case.
The picture is showing a tiny gap between the tire and fender, right now Chicago temp is only 50, it's cold. after a couple of miles driving, the tire will scratch the fender as you can see the scratch mark.

Hmm, I'm going to check mine ('14) because I've noticed sometimes while parking and the wheel turned fully, I hear a bit of an odd noise & feel some roughness. I had attributed it to the sharp angle of the tires on the ground, maybe it's rubbing....
