“We are seeing alot in the new media about Ford explorers and exhaust issues. About a year ago we experienced similar issues with our FLEX. My husband has a 30-35 minute highway commute to work, was arriving at work and coming home feeling ill to the point where he would need to sit or lay down, it would eventually pass. We noticed a strong rotten egg smell in the vehicle. Ford dealer had the car for 2 weeks, was able to duplicate the odor - related to running A/C at highway speed - unable to figure out what was causing it. …”

I had it towed over to the Ford dealer and 2 days later they looked at it. They stated the water pump catastrophically failed, leaked into the oil pan, overfilled the oil pan and cause coolant/water to be circulated through engine causing no compression and seizing the engine.
