I have a 2015 Equinox with a 4 cylinder and automatic transmission. I've taken it in within the past six months for the same issue over four times and my answer from the dealer is they can't duplicate the problem. While slowing down coming off a highway or coming to a light my truck buckles and jerks like it stays stuck in high gear. My truck is my office and I am always on the road. At this point I am not sure what else to do about this issue and I wanted to see if anyone has any suggestions.
