My 2017 Expedition EL equipped with Mechanical load leveling is making passengers in second and third row nauseous. This issue became more prevelant after an oil change at a Ford Dealer also, around this same time I had towed a small utility trailer with about 600 lbs or less. It has become so bad that no one wants to ride in it. I feel it somewhat in front row. I sat in second row and confirmed that feeling of nausea. Does anyone else experience it or know what is going on?
