From day 1 when I am pulling into my driveway with my C90T, or just going slow and making a turn. I hear what sounds like a small rock or BB rolling around inside of the fake gas tank or center consol. I have taken the center consol, and both sides of the fake tank off, and given them a hard shaking in hopes that something would rattle or fall out. No rattles or noise until I put it all back together and test it. Anyone out there with a C90 hear the same noise? or know what the heck is making the noise?
