Peace,
Obviously, that's all incorrect. Those aren't misconceptions. Islam teaches us that Jesus pbuh wasn't crucified nor was he God/son of God! Jesus pbuh is was only a messenger and a prophet sent by God to humanity. There were many prophets before him who gave the same message: "Worship God, and God alone!" This message is not alien to Islam. Actually, it's in the OT, one of the Ten Commandment:
Exodus 20:3 "You shall have no other gods besides me."
Peace,
