I noticed the smell when I brought the car. However, it was not bad, but when I had the car serviced, the next few days the smell got worse and became unbearable. I took it to the dealership and they changed the filter, then told me the smell was because the ac was so good and strong that's why it had that smell.(?). The smell went away for a week and now the smell is back and worse than before. I have to start the car, run the air for 10 minutes with the window down to get rid of the smell for the each ride.
