“2018 Kia niro plug-in hybrid, 16,235mi. Vehicle has been in 5 times in last several months for a total of over 30 days in shop. Transmission will do a very hard downshift intermittently when stopping. Makes vehicle dip hard..noticeable on dash cam video. On harder acceleration, power train has trouble deciding what to do and often there is a noticeable delay in acceleration. Feels sort of like it is slipping, but is a delay in powering the electric motor fully and starting the gas motor.this has caused a couple close calls when pulling into traffic expecting the car to react appropriately. …”
