I, too, have had the "stutter" problem on our '17 Niro EX...and our vehicle has now over 6500 miles on the odometer. The shuddering is very obvious when the Niro is right at the junction of coasting and needing a bit of acceleration to maintain speed. It feels just like a misfire (like someone pulled a plug wire on one of the cylinders) except the MPG's don't seem to be affected...as the car still averages over 52 mpg banging around town and mid-to-high 40's mpg on the highway. This jerking occurs in both EV and gas modes which , of course, leads one to believe it is not an engine misfire but perhaps a transmission/power train problem. Maybe the mechanism to provide a smooth transition between gas and EV modes is at fault?
The car has been twice to the dealer for this issue, but because no error codes get thrown by the OBD, they claim nothing can be done to remedy the problem. Supposedly, this complaint was registered by the dealership's repair facility in such a manner that ALL Kia maintenance personnel worldwide can see the problem and share remedies when available.
