So this is a new noise that I've been hearing. I'm going to do my best to describe it, its a 2012 RRSC. At first I thought the screeching noise was coming from the speakers, it comes right from the center of the dash. Then I hear it when I break lightly or heavily sometimes, but it continues screeching even after I brake. And sometimes it only does it when I'm turning. The sound comes from the center of the dash, sounds like maybe the booster? It sounded too like sound from the center speaker. And I always hear a short 2 second screech when I turn the engine off too. Has anyone ever encountered this? I'm going to try to take a video too, where could I start to troubleshoot it.
