Haste not carried into opponents turn.
Haste, is not being honored on opponents turn. Example. I have creatures can tap for any mana color. They enter with haste on my turn. End of my turn they get summoning sickness animation and can not tap them for mana.

Depends on the card granting haste. Enduring Courage, for example, grants haste only until end of turn. So of course haste is gone on your opponent's turn in such a case, and summoning sickness applies due to you not having controlled the formerly hasted creature continuously since your most recent turn began. Haste does not negate the condition for summoning sickness, it merely lets the creature ignore it so long as it has haste.
