"The affected vehicles have left and right side curtain airbags that may not have been manufactured properly," said NHTSA in its recall summary. "The airbags may not position themselves as intended during deployment, increasing the risk of occupant injury in the event of a crash."
There are no accidents or injuries linked to the recall, BMW told federal safety regulators.
A stop-sale order has been issued on the cars until they are repaired.
The affected Phantom sedans were built from May 22, 2015 to September 23, 2015.
Edmunds says: Owners of these cars should wait for their official recall notice and then schedule a service appointment. But those with an immediate concern should contact their dealer now.
