I have a 2017 that seems to sputter while driving. It happens mainly when I am driving with a steady pressure on the gas trying to maintain the speed limit. The sputtering starts around 30 mph and is most notable around 45 mph. The best way to describe the feeling would be like you’re driving into a very strong headwind. The car will buck slightly then smooth out and repeat. I had the injectors cleaned with no change and the RPM gauge does not show any sign of sputter while this happens. Also no check engine light has been noticed while this happens. I’m thinking a transmission issue since it seems to be in those between speed shifts. Any thoughts
