Is it safe to ride on this wheel?
I just noticed there’s carbon deformation on my rear wheel. I am told that it was caused by exhaust heat (I recently traveled and the bike was on the rack)
Is this wheel still safe to ride on? I put the bike on the same rack same position many dozen times and this never happened before. Maybe I never noticed it before but pretty bummed to see the wheel like this on top of other issues I have been having lately.

I wouldn't do anything without asking the wheel manufacturer. Contact Giant and ask them. If you are seeing that, the wheel got hot enough to soften the epoxy and deform the wheel.

Any more to the story? Sounds as if someone (shop?) explained what happened, did they offer an opinion? The only way I can imagine it would be safe is if the wrinkles are only in some cosmetic, tape-like layer. Probably only Giant could tell you.

Just for the sake of curiosity, can you feel the ripples?
Regardless, I can't imagine riding on a wheel that was heated to the point warped. That means its structure was weakened and changed...

My sister in law did that to an aluminum wheel. Burned the tire off and distorted the rim.

Impressive the continentals survived this
I would ride these for commuting at 25kph
not descending at 90kph
another reason to buy EVs. ICE cars destroy bikes.

Or, you know, put the bike in the trunk.

I had maybe 500 miles on the tires so yes they are fairly new.

Is that a carbon faring rim with a AL core or full carbon? If you take the tire off, is there shiny metal inside? If it's a faring wheel, I wouldn't sweat it.

I'm a mechanic at a Giant shop--and I'd bet a considerable sum of money that Giant would not say that's safe at all. That's a full carbon rim and the layup is compromised.
Unfortunately the damage is not related to riding so it does not quality for Giant's Carbon Confidence program. If they have a replacement rim in stock you should expect to pay for it and a rebuild of the wheel or for a new wheel, which may or may not be less expensive.
