Hi all. Had something strange happen tonight...Was driving in 5th and went to downshift into 4 because a small incline. Rev matched and slid into 4 and got an awful burning rubber smell at same time. Maybe I revved a little higher than needed, but definitely didn't over-rev. Smell is intense. Any thoughts on that? Cars brand new...has 4500 miles on it. I'm thinking maybe coincidentally I picked something up off the road that burned itself into the exhaust pipes but not sure.
