So I was going about 70mph yesterday, I think once I hit 60-65 my car started vibrating and getting worse at 70 and 75. What do you think it could be?

I've got to take the car in for a number of small fixes anyway, but I don't want to be stuck with some FWD loaner car as my AWD is awesome in this weather, to say the least. Anyways, I still have 5,000 miles on the powertrain warranty, so I suppose it wouldn't be bad for them to give it a once over to see what all I can still get fixed.

Other than that my backup sensors beepers stopped working, which I don't actually mind, haha. My rear shade won't stay down and some work the body shop (at the dealer) did needs some attention.
