I have an 02 Xterra that after short trip there's a strange burning smell coming from the rear of the vertical. I check the brakes and there not hot, or even warm after a trip. It just started do it in the winter time, mostly on real wet day. so im wondering if it water an road gunk getting on the exhaust or something serious? Is this a conman Problem? Thanks.
