The facility near Kuala Lumpur International Airport (KLIA) is being touted by Malaysian authorities as the world's largest low-cost airline terminal.
But the terminal, dubbed "klia2", has been hit by repeated delays, construction issues and costly overruns that have sparked a parliamentary investigation and harsh criticism of the state-linked Malaysian airport operator that built the terminal.
"There are many concerns, especially on functionality, safety and security of klia2, which are paramount to our staff working efficiently, and for our passengers to have a seamless travel experience," AirAsia CEO Aireen Omar said in a statement.
She had said in a statement late Tuesday that the fast-growing airline -- whose success is seen as a driving force in the decision to build klia2 -- would refuse to move into the new terminal from an existing one until "unresolved pressing issues" are addressed.

AirAsia has been a harsh critic of klia2's delays and ballooning costs, and says it has been shut out of decision-making, despite being the facility's biggest and most important future tenant.
AirAsia's statement yesterday had warned about "depressions" on a runway discovered by independent inspectors.
"We are more than ready to move to klia2 but we must move under the right circumstances," Aireen's latest statement said, appealing to Malaysian Prime Minister Najib Razak to intervene to help "resolve this national issue".
The country's airport operator Malaysia Airports Holdings Bhd (MAHB) has said AirAsia and other carriers will have to move to klia2 by May 9, when it plans to close an existing low-cost terminal nearby, which handled 22 million passengers last year.
MAHB, which is building klia2, did not respond to an AFP request for comment.
The government and flag carrier Malaysia Airlines are already under fire for the still-unexplained loss more than three weeks ago of flight MH370 with 239 people aboard.
The flight lifted off from KLIA's main terminal and disappeared shortly after in a mystery that has shone a harsh light on Malaysian authorities and aviation safety.
Malaysia now believes it crashed in the Indian Ocean, but no proof has been found and the sequence of events aboard the plane remains unknown.
