NHTSA Complaint #11452958 — 2019 KIA NIRO PHEV

I don't know what components are involved. When attempting to move forward from a stop the car does not respond immediately. Then there is clunk noise and a lurch forward. Sometimes when this happens it feels like the car has been hit from behind. The problem began about a year ago and has been into the dealer's service center several times. I believe during one of those service visits a reset of something was done that seemed to resolve the issue for several months. The problem is intermittent. Dealer has been unable to reproduce the issue, but stated the last time the car was in for service that another customer with the same year and make was having the same symptoms and a tech that had been allowed to use the car for over a week did not experience the issue. No warning lights or codes are associated with the issue. A car that fails to move forward on a green light is in danger of being rear-ended placing the people in the vehicle and surrounding vehicles at risk of bodily injury. The vehicle has not been inspected by anyone other than service staff at the FOlsom Lake Kia dealership. On February 18, 2022, the vehicle had no power (automatic doorlocks didn't work, etc) could not be started and was towed to the dealership where it is now.
