What causes a buzzing sound when i first start my 09 sonata sounds like its coming from the power sterring pump or something close by?

A buzzing sound when starting your 2009 Sonata, particularly if it seems to originate from the Power Steering pump area, could be due to low power steering fluid levels, which can cause the pump to struggle and create noise. It might also indicate a failing power steering pump or a worn-out serpentine belt. Additionally, air trapped in the power steering system can lead to similar symptoms. It's advisable to check the fluid level and condition, and if the noise persists, consult a mechanic for further diagnosis.
