I've had the same problem with my Cruze. The smell is not constant...mainly when the heater is running... and when it is very cold outside. The mechanic smelled it the second time I brought it in but has been unable to find the problem.
They replaced the air compressor, cabin filter, and we have done the dye test. They have been unable to find a leak. We have spoke with Chevy and they had an engineer come out and have been unable to duplicate the problem.
The dealerships have been told not to replace any parts unless they find a leak. They are working on a solution. They had my car for 4-5 weeks... mechanic was very nice... but I told him that just because Chevy can't figure out the problem doesn't mean that I should have to smell it. I'm sure that it can't be very healthy to smell this.
