Still under warranty? Without hearing the noise myself, I can't say for sure, but there is a TSB relating to excessive wind noise from the rear interior of the vehicle. TSB 10-08-58-001F talks about sealing a "C" pillar void and also possible replacement of a rear body panel insulator. I'd take it to the dealer for diagnosis and possible repairs.
