Hybrid Noise

Hello,
I have a 2015 Sonata Hybrid Limited. For the past month, I've noticed a noise when it transitions from the electric motor to the gas engine. Sometimes it makes the noise when going from the engine back to the motor, but mostly from the motor to the engine. It's a vacuum sounding noise, and it has become louder over the last couple of weeks. The car runs well, no issues with performance, only the noise.

I've got an appointment, but that's two weeks away. Does anyone know what may be my problem?

Thanks,
AzeraFirst
