I have a 2015 IQ with automatic transmission that recently started bucking while driving. Not sure if it is bad gas or signs of a transmission problem. Has anyone experienced this? It was subtle at first... almost like the brakes were sticking and then i noticed it becoming more intense. It happens very rarely (one x a month or 6 weeks) but it seems to be getting worse and more frequent. I thought it was how the CVT transmission shifts at first since it would only buck once or twice but now it is sometimes constant and not a good feeling on the highway!!!! Help.
