Hello everyone. I'm new here and trying to figure out why my rx7 randomly makes a really loud buzzing noise? It will do it so randomly I can't even predict it. I thought it was only on corners but it will do it now just sitting at a light! There is also a chime/bell noise that's not like when I got it when I first put the key in. Its like a bell beeping a few random beeps. Ideas?
