I was going really slow down an easy dirt road in 4L and all of the sudden the steering wheel spun violently two full turns left in under a second on its own. This threw my right arm off the wheel where it hit the shifter with force leaving a large bruise. Steering system fault warning appeared, the tire position on the camera screen was stuck all the way left, and i could no longer disconnect my stabilizer bar. i turned the car off for 5 minutes then back on and everything was fine. If this steering glitch happened at highway speeds I could have rolled the car and dies. Luckily i was going really slow on a relatively smooth part of the trail when this occurred and it only shook me and my passengers up a little and bruised my arm. If the trail had been more steep or if there were rocks on the trail, this could have flipped my vehicle.
