The problem is Intermittent. There is a definite exhaust odor in the cabin area of the car. The car can be driven or parked and the odor will appear. The dealership has been notified, but because the problem does not always occur I doubt that they will waste much time in resolving the issue. Going into the future I will purchase a carbon dioxide detector to see how bad the problem is and if there is a possibility of health problems to consider if I continue to drive the car with or without the smell of exhaust fumes inside the cabin.
