There is a smell, like really dirty socks from the dash. It does not happen every time the car is used. To smell it you have to start the car and it is there. Sometimes the heater is on or the air. It also becomes less noticeable with time, up to 10 minutes. It is a very strong smell. I don't believe it is the catalytic converter, which has a different smell like rotten eggs. Because it goes away most the time I don't think is a dead mouse or something like that. It is not a dead animal smell. Help. You want to jump out of the car the first time you smell it. I do not know if it is a chemical or not but my noise burns a little.
