Since it looks like my JX is going in for the heated steering wheel problem, I might as well bring up another issue. When I start my car, there is a nauseating sour smell that blows from the vents for about 1-2 minutes. It doesn't happen every time, but it is pretty consistent. The smell is usually gone until the next time the car sits for awhile, but sometimes I'll be driving on the road for 1/2 an hour and the smell will waft back in again. It have to crank up the the fan on high for awhile to clear it. What could be causing this? I never use the recirculate feature. I can only describe it as sour, maybe almost like an epoxy curing kind of smell. Any thoughts on what it could be? Car was built this April and has been doing it since it was brand new (has about 5k on it now).
