So I took another trip to the dealer today. Apparently my first trip the guy didn't actually check for what I was talking about.
Took it on a road test with a tech and heard it loud and clear. I was told by the service manager they've already repaired 6(!!) 2012s with super low milage that have this problem. Has to do with the control arms and the bushings. They also said they've been given indication that this may end up being a TSB for early model 2012s since it's such a widespread problem.
Parts are back ordered for a month, but he placed an order for mine. Reassured by my visit today, for sure.
Anyone who is having this problem, get your car into your dealer and have them order you the parts. It's a relatively minor issue but very annoying - get it taken care of!
Deysha, I'll let you know how things go after my parts come in. If there's not resolution after that I'll definitely be contacting customer service and possibly escalating the issue. I love my mustang to death but won't hold onto it if this issue is not easily fixable.
