I need help. My Sonata developed a high squeek that lasts a second or two when the Hybrid Starter Engine kicks in at start-up and sometimes when excellerating from a stop while driving. The dealership replaced the HSG motor under warranty but that did absolutely nothing. Anyone having this issue? Can barley hear it in the car but outside it’s loud. Very frustrating!
