I've put this off for far too long...
It's made noises off and on since winter, at least. But I didn't have the cash to look into it and it didn't seem THAT serious. But now it's worse, and I have at least enough to have it looked into. I'm still hoping it's something other than struts...I think that's a fairly expensive repair.
I'm so glad my car is mostly warranteed. At least I won't have too many expensive repairs in the next few years.
