AC seems weak in hybrid?

To be clear, I believe you mean the ICE when you say "hybrid engine". It does not run in EV mode, correct. The AC compressor should run off the EV battery (at least when the engine is off), so you should notice no difference in performance whether the engine is on or off. If the EV battery gets low enough, it will turn the engine on to charge the battery. It works fine for me on my Santa Fe hybrid, which has the same system as the Tucson hybrid.
