I searched the 4th Gen forum but didn't find an answer.

Is Rain-X 2 in 1 fluid safe to use in my Optima? I remember reading somewhere the additives in this one screw with the sensors.

Or do I just use the regular blue one :

I always use the Rain-X washer fluid. Works great. I have a 2019 LX. I don't have any rain sensors in my vehicle. Not sure what other sensors it could mess up.

There was a class action law suit, but evidently nothing came from the suit, at least award $$:
