Hi, I currently own a 2016 CT Special Edition (my second CT), and I'm loving it so far. However, there has been one thing that has popped up about 1 month into ownership. Whenever I traverse over slightly bumpy roads at a certain speed, or whenever I make a left turn at a certain speed, I notice an annoying persistent squeaking sound coming from the right/rear of my car (sounds like where the battery might be). It alsmot sounds as if something rubber was rubbing against some hard surface. Has anyone else experienced this? Is there anything I can do about this sound? I told the dealership about it during my car's oil change, but they didn't seem to be able to reproduce the sound back then. Now, it's persistent as ever. I'm just afraid that the battery might have come loose or something, as I've check every possible part that could've been making the sound.
