Title says it all. Was driving the other day and the most horrid smell started coming through the vents. Smell seems to be mostly from the driver side. I use it constantly so its not like I just turned it on for the first time and it has been like this for more than one ride. What can cause that? Did a little Googling and saw a lawsuit for 2012 Corolla's about this exact issue. Mine is a lease so I'm gonna take it to the dealer, but just curious what it may be ahead of time. Thanks!
