Hello Guys, I am a happy owner of IS250 2012 and I have couple issues. 1. my parking sensor sopped to make sound utter I change my multi media console, I can see the distance on my speedometer but no sound (muted). I tried to turn it off and on, tried to disconnect my battery for hours and no change. 2. I have strange noise on rear right side like a vibration or fuel pump trying to pump air (with full fuel tank). if any one know how to fix it ??
