So I have a 2010 FX35 AWD and i keep getting this burning smell under the vehicle after driving around for a while. Occasionally noticeable in the cabin, but usually only smell it right after I get out of the car after driving. Only new thing recently is new tires. (All 4)

I've read that if there is a variation in the tires that it could be the differential/transfer case getting hotter than normal.

All fluids are at the appropriate level and no leaks that I can see.

Any ideas?

Thanks!

Thanks for all the suggestions.

I checked under it this morning (put it up on ramps) and nothing seems to be leaking or be stuck to it anywhere (like plastic and stuff)

I'll get the engine covers off later and see if I see anything seeping from the valve covers, not sure if that is the problem but you never know. The smell seems to be coming from under the car, don't really smell it in the engine bay.

Thanks!
 
Recently one of my rear calipers was dragging slightly and heating up. That was causing a burning smell that I only noticed after I had driven for a while and stopped.
