Anyone else being told that many of the ordered vehicles (X5s) in SoCal are "stuck at port" (on carrier) for unexplained reasons?

Am off lease with my X5 (I stupidly turned it in due to maintenance issues before my new X5 arrived). Am driving a free loaner 3-series until my new X5 comes in. Was told 2 weeks ago that it would be at the dealer and they and I are still waiting on it to clear port. The dealer is claiming that there is a number of vehicles that are stuck at port.

Anyone else dealing with this or is this a line?
