I have a 2018 LC, going on two months ownership. 33k miles. While sitting at a Home Depot parking lot today with the AC on, my cabin begins smelling like gas. Immediately turn off the car roll windows down for a bit. Started it up again and I can smell the gas again. Not a really strong smell but very noticeable, almost like a sweet smell of gas. Drove the car for about ten min, ac off windows down. The smell seemed to subside. Roll windows up and turn on ac again and immediately smells again. Side note, the two months I’ve had this car, it has struggled to start four time. Any input is greatly appreciated

 

Mine smells like *** on startup, as if someone pissed in the vents

 

Sounds like you Way need cabin air filters.
