What owners wrote
Engine/transmission becomes very sluggish as temperatures drop and the transmission seems to be "engine braking" the vehicle, making coasting nearly impossible. Putting the vehicle in neutral allowed the car to normally coast but once back in drive, acceleration was taxing. The vehicle lacks any power and is ruining the fuel economy trying to get the car up to speed.
The contact owns a 2018 Kia Niro. The contact stated while driving at an undisclosed speed, the engine revved up.
