2017 Elantra Sputter
 
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

Did you notice if this problem showed up after a recent gas purchase? If so, a can or two of "Dry Gas," or what ever your auto supply store carries might help if there happens to be water in the fuel.

Same ole situation
 
My 2017 Elantra started doing this today after I filled tank up. I'm hoping after I run the tank out it clears. I've put seafoam injectors cleaner in it and helped a little. I thought about a bottle of alcohol but I'm nervous about that in a newer car

Whatever you do , don't add any dry gas that contains METHANOL , only isopropyl alcohol.

The methanol can cause problems with the catalytic converter.
