The reason some people are having pain in the left hip area is there is literally a bolt sticking 1.5” into the left hip. There is no bolt on the right side. I followed the instructions from forums to insert foam in the seat and found the bolt. My guess is there was a production line error where some vehicles had a too large bolt added on the left. I’m going to contact GM about this and try to get their attention. There is no reason to have the threads of a bolt stick 1.5” into the cushion.
