NHTSA Complaint #11495928 — 2019 KIA NIRO PHEV

I have a used 2019 Niro PHEV. I started getting a loud jerk when starting from a full stop. At first it started happened in EV mode only but I've had it happen in Hybrid mode a couple of times ( not sure if the engine is actually working or just on for Heating). The sound and jerk can best be described as what happens when you drive a stick shift and you pull the clutch too quickly in first gear without any gas and the car jerks forward. It also feels like I've been rear ended. The car feels unsafe the drive. There were no warning lights. Dealer hasn't reproduced it yet. I just brought it in. Please see these forum posts about this issue.
