    A/C Refrigerant Leak?

    9 month old P3D+. Started noticing that when I first start up the car and the A/C comes on, I'm getting a very distinct vinegar-like odor coming from the ventilation system. Puzzled me for several days, couldn't figure out what it might be. I know a lot of cars sometimes have a mold problem...
