Experiencing exhaust fumes in the car. It's causing eyes burning and headaches after driving the car for 30 minutes. The Dealer checked and found nothing wrong but every time after driving the car for about 30 minutes, I have head ache and my eyes burn from the air coming through the vents.
How can I troubleshoot where the exhaust leak is?
What could be the source if the exhaust gasses are getting into the cars cabin?
