While driving my vehicle I began to notice a clicking noise in relation to my tires/speed. No sensors came on, all gauge readings were normal. I pulled over and viewed the tires to check for a flat, all seemed fine and pressure was reading normal. When I resumed driving, I came back into my lane turning slightly left and noticed that the steering wheel began to vibrate. I slowed the vehicle again and put on my hazard lights while attempting to reach a freeway exit. The vehicle began shaking as though I had a flat but again I did not. I decided to turn off an exit and when I attempted to make a left turn into a parking lot, my front passenger wheel flew completely off. My two four year olds and I were then left without control of the truck, finally grinding to a stop blocking two directions of traffic on a Highway unable to get out of harms way. It was night, cars were coming in either direction. I had to emergently remove my children from their car seats and get away from the vehicle to safety. The lug nuts/bolts were completely sheered off. The wheel flew into a field several yards away from the vehicle. If I would not have exited the freeway, I shutter to imagine what would have happened to us as other large trucks would not have been able to stop at the rate that we were forced too. Please. This vehicle/part needs an official recall!
