While slowing down to make a left hand turn at an intersection, my vehicle suddenly lost power steering and the entire system completely shut down. There was no electronic function during that time. I had to put the vehicle in park, turn the key to the off position and then start it back up. It has happened multiple times, both at low speeds in drive and reverse. This would have caused a collision if there was oncoming traffic at the intersection at that time.

When driving with the 4x4 switch in the auto setting the car would jerk while driving at high speeds. Almost seemed like the left front tire would engage on dry pavement. Also there is a loss of steering while the vehicle is in motion. Speed does not change when it happens. Seems to happen more when driving around a corner. Loss of steering happened for a split second or multiple seconds.

The car was slowly making right hand turn when we heard a loud noise and stopped the car Once we got out, we saw that right wheel was completely torn out. We have videos and pictures. If it would happened on the higher speed, we would be dead. The car shop told us that they never seen anything like that in the past. Per their report, upper control arm broke off then the rest followed: lower control arm, ball joint, outer tie rod, poss inner tie rod, sway bar link, abs sensor connector. Consumer also learned from dealer that certain parts do not exist anymore and new ones are available.
