Noticed recently that when I put the car in the garage upon coming home, I smell burning rubber. It seems to come from near/behind the left rear wheel.

Once I saw steam coming out from behind the left rear wheel upon coming home, not nearly as much on the right rear. The road was covered in snow that day, so it could've been evaporation of snow/water.

No smell from under the hood.

Not sure if it means anything, but I go up steep hill to get home.

What could this be?

Drive a short distance and then feel the rear wheels. If one is hotter than the other, you have a brake problem.

BE CAREFUL NOT TO BURN YOURSELF!

If you spray a little water on the wheel and it steams, it is too hot to touch.

If a short drive does not yeild a difference, try driving further.

You could finish by checking the wheels after climbing your hill.

Its your brakes, same think happened to me with smell but i let it go and ended up having to get 4 new rotors as well as a front brake line.

Rear caliper sticking? Parking brake shoe stuck? Jack up the left side and try to turn the wheel by hand. It could eventually get hot enough to start cooking your wheel bearing grease.
