I am having surging problems with the cvt transmission. this problem is intermitting. After I accelrate and reach my cursing speed the cube starts surging, there are no fluctuation on the rpms or speed. I had the fuel systems clean thinking it fuel problem. I have been to the dealership twice, both times the dealership couldn't reproduce the problem. It feels like a slipping band in the transmission. Did anyone in this forum have this problem if so how was it rectify?
