Had the car for about a month now and i'm loving it (besides the mpg).
Lately I've been hearing a hissing noise coming from the front axel.
Its a constant noise, can't hear it from high rpm but that could be due to the exhaust noise.
Anyone know the problem?
Also a noob question, I hear creks or clicking noises near the rear window,
something sounds loose in the interior of the car.
I know for sure its not the infamous exhaust noise.
should i just take it to the dealer?

 

Check the passenger seat belt for that "rear window" noise. Lots of us had the belt clanking around making that noise and it sounds like its coming from everywhere in the back!

Not sure about the hissing noise. Almost sounds like a stuck brake pad dragging on your disc.
