I have new Palisade and smells like rotten egg. Took the vehicle to the local dealer and they have replaced driverside seatbelt assembly but odor still stays. I have brought back the Palisade for deodorizationsSo I don't drive my car a ton right now since we are at home so much. A few weeks ago, I went to get gas for my mower and got a tiny bit on my WeatherTec floor mat (I wiped it up.) I don't know if it reacted with the floor mat or what, but my interior smells really bad now. It doesn't smell like gas either. It smells a little like the leather seats, but only way worse. It's so hard to describe! Anyone else's interior gone from that "new car smell" to something way worse????? I don't know what to do to get rid of it either.
