The 2021 Kia Niro draws the most complaints around its dual-clutch transmission, with owners describing a recurring issue where the clutch fails to fully disengage, causing the vehicle to creep or lunge forward even with the brake pedal pressed. Related to the drivetrain, some owners report an unusual clattering or rattling noise from the EV motor and driveline that changes pitch with vehicle speed. The backup camera is another recurring concern, with owners reporting that the display goes black or the camera simply doesn't activate when shifting into reverse. A single report mentions rear brake rotors developing pitting at relatively low mileage, with the owner noting the dealer declined to address it under warranty.
