During summer months with air conditioning running, the cabin of the car fills with heavy exhaust fumes whether the air is recirculated or outside air. Daily commute is less than 10 minutes and traffic is light. I keep my windows closed when air conditioning is on. I haven't noticed this problem in the winter. I am worried about being exposed to dangerous carbon monoxide levels in the car. This occurs every time the car is driven both on the freeway and surface streets.
