rear wheels sloped out at ground level??????????????
A few things, sagging springs, worn suspension parts, alignment is wrong, worn bearings. I would have this checked out very soon, you don't want to be driving down the road and have your tire and wheel pass you.
That is worst case.
Are you talking where it's so bad you can see it like a LOT? Or it was at an alignment shop and they told you the camber was off? That car has 4 wheel independent suspension, odd both sides would do it..and at same time suddenly? It's also all-wheel drive, so it will have a differential. bent axle? did it take a hit? A floor jack...nawww...
