My 2008 Sonata (which is new to me) makes sounds I don't like when I go over moderate bumps. To me it sounds like a loose ball joint. What I'm wondering is if I take it to my local stea... uh dealership, and nothing is wrong, will they try charging me some "diagnostic fee"? Obviously this sort of thing may vary by dealer, but I'm just wondering (before I go in and get a nasty surprise) if that sort of thing is common. Hopefully if it is in need of repair the warranty will cover it and I'll get out with my wallet still on my butt...
