Strange Smell

It's no big deal , I think thats your Power Transfer Unit low on fluid , they had a recall on them I think if you needed it , and it's covered under warranty if you need a new one . They had problems early on because they had seal leaks and the fluid would go out, the unit would heat up , and you get the smell. You have an 07 ' as I noticed ( like myself ) and I had that problem, but wasn't too bad, was a matter of getting it topped up ( came low out of the factory for some reason or another ) . I hope it's not something else however...
