6 months old? take it to Lexus and ask them....but it looks like some kind of cleaning chemical got on there...or a cat marking his territory (urine)?

Do cats lift up a hind leg and urinate? I thought that was a dog thing. I think cats squat and pee to mark territory.

Anyhow, I'm almost certain those stains are not caused by animal urine. It kind of looks like clearcoat failure mixed with embedded brake dust.

99% certain that's what is referred to as "chemical burn". It means someone used a chemical they shouldn't have when cleaning the rims. Only way to fix it is to have the wheels dipped which will run you about $150/rim. It would be worth playing dumb with Lexus and taking the car to them to see what they can do, but I'd be surprised if they don't tell you this was caused by cleaning the wheels.

Default Many GS F Sport got same problem

Many members in 4GS forum got the same problem, and dealer refuse to repair for couple unlucky members.
My 2013 GS got the same too but not really visible.

I have used a metal cleaning "cloth" more like a fiber mix pad that has some sort of cleaner on it. I use it on my cymbals to remove gunk. There is an automotive one as well. These are gentle cloths ( sort of a wad of insulation type fiber) and might work. It's like a brasso cloth that you rip off in the can. It has worked on stains on my winter wheels. Does not scratch the alloy.

There is another product I use called Groove Juice for cleaning various metals. It is acidic but I doubt it would cause more problems.
If the black marks have etched off the paint, I don't think either of these two products will work. If the black is on top, they could help.

Unfortunately this is not uncommon....

Black cheetah like spots on the stock rims of 2014 IS250 F SPORT
Is 350 rims ruined by bodyshop

... this is almost certainly the result of improper wheel cleaning and will likely need to be refinished to completely remove the damage.

Could always do what I did: plastidip those suckers for $8-$10/wheel, then rip it off when the lease ends. Won't look as nice, but if it bugs you enough, it might help ease your pain.

Your SOL..... there is not fixing that.

The finish is permenantly stained and discolored from the wheel being improperly cleaned.

Odds are it was sprayed down with a chemical while the wheel was still hot, and the chemical dried up.

This can happen on any wheel finish, but this specific Lexus finish seems to be the absolute worst in this regard. This semi-gloss gunmetal finish that Lexus has used on their cars for over a decade is definitely very sensitive and odds are, if you look at 10 cars with that finish on the wheels, most if not all with be similarly stained. If the wheel is not stained, the owner was probably an OCD by-the-book detailing nutjob that took an hour to wash their wheels every cleaning and the odds of finding a car that belonged to someone like that are slim to none.

Happens far too often...You have to use caution when using the heavy chemical based wheel cleaners, some even have acids in them to break down the brake dust. When I opt for an acid based wheel cleaner I ensure the wheel is cool i.e. don't drive 100 miles stomp on brakes then go straight to wheel cleaning, let them cool down or start early in the morning prior to driving or even driving little, make sure to rinse all that chemical thoroughly. If you keep up on the wheel regime you should not need to use these types of cleaners, honestly I have been able to maintain wheel cleaning with microfiber and rinse less wash thats safe for paint with the oem brembo pads.

I would never use wheel cleaners at car shows as you would not be able to rinse away all the chemicals.
