I'd like to know is it ok to lift the Ioniq5 one corner at a time to say install winter wheels? seems there'd be possible stress on the battery compartment.

There is no jack supplied. and there is no mention if using a jack in the manuel. the only image shown is 4 lift points and a picture of a hoist which as we now lifts the entire vehicle.

I done it with 1 corner at time, what was fearing me was more about the weight of this car 4700 pounds and the capacity of my hydraulic jack.
I used my old 2 tones hydraulic jack and it had no trouble jacking all car corner.

Don't fear about the battery (Just don't jack under or course) and use normal jacking place. They made a security space perimeter around battery and added a frame for this battery to add rigidity for adding crash protection next to the car frame.
