Apparently when I brought my 2008 LS to the dealership yesterday for a few tweaks they called me back and according to their inspection found that both front struts had been leaking fluid, for most likely a few months. Everything is stock on the car. I'm at 37,000 miles and it struck me as odd. From what they said GM catagorizes everything from a 1-4 rating with 4 being the worst. Both of mine were at 4 with the left front being worse that the right. Anyone else heard of this happening?
