Hi all, I got my 2013 is300h F sport two months ago and I'm also having issues with the audio system. Its been on and off for past 5-6 weeks now I have no sound at all from any sourse including voice command on steering wheel. My car is currently in my local Lexus dealer having this looked at, they are thinking its the amplifier at fault and should be replacing it tomorrow, luckily i bought the car with a Lexus warranty so this should be covered. Will update on this when i get car back hopefully tomorrow.
