Holy crap they had your car for 4 days? I seem to notice it more when the car is 1st started but like I said not all the time, today there was no smell at all. What do you think it smells like? Sometimes I think it's an exhaust smell but sometimes it almost smells like a burning smell.

Also you should add the word "smell" to your topic title as that may get more people with the issue to reply. I also don't think its and AC issue as it happens with the AC off, it has to be some kind of ventilation issue.

The strange thing is I have a weird sound when starting and someone mentioned the compressor, I wonder if the 2 are tied together? Maybe the compressor is doing something funny at startup that is creating a buring smell.

I'm glad you posted this so I know I'm not the only one. I'm betting there will be others.
