Consumer Description

Immediately after getting Kia's latest recall "Voluntary Emissions Service Campaign" software update, my transmission began to Hard-Shift between neutral and 1st gear, and when slowing down, from a gear to a neutral position with the transmission. The car has lunged a few times when going from neutral to 1st gear position--concerning. This is most noticeable when car is cold, but is still always noticeable. Stop-and-go traffic it's also most noticeable. I have notified local dealership by phone message and email but have not heard back in 2 weeks.
