The vehicle has strong exhaust fumes inside. It has gotten so bad people at work smell it on me. I even went to the doctor because I was trying to fall asleep while driving, I am confused when I first arrive places, my lungs feel like I am inhaling fire, I have the most painful headaches, and I am nauseous around the times I drive my car. My two girls are experiencing the same problems. But if we do not drive the Bronco on the weekends, no problems. My husband put it on the life at home and there are bolts missing from the dust shield, the ones there are loose, he had to tighten the bolts on the heads, and the convertor has hot spots on it. I have to drive at all times with a window down. The exhaust fumes can be smelled from outside as well. I have taken it to the dealer and was told there was no smell. I am scared at this point to drive it.
