No warnings of any kind went off; I wasn’t even going 2 m. P. H. And hit a piece of wood that was right on the edge of the grass next to the road at the park. This is dangerous, especially at a park or other places where smaller children are present if I get that close to something and the none of the sensors go off letting me know there is something/someone that my vehicle could strike if not careful. I have not had it looked at yet, but plan to. No warnings of any kind have went off and it was functioning properly prior to this. There is severe damage to my vehicle.
