Noises During Shifting Problems of Kia Motor Optima

Kia Optima 2017 hybrid. 26k mileage and automatic transmission become very clunky, car jerks when shifting on any gear. Not stable driving, strange noises under the hood especially when vehicle goes uphill and even on straight road car twitches. No oil leaks from the bottom.

While driving approximately 25mph I heard a loud 'bang'. Shortly thereafter, my Optima would periodically shift gears very roughly on downshifts. There was also a 'clanking' noise present on the rough downshifts or when the Optima was shifted into reverse. Upshifts while accelerating seemed to function normally. I immediately brought the car to the dealership where it was purchased. The dealership determined a bolt had snapped on the transmission mount causing the transmission to knock into the engine when it shifted. It was the belief of the dealership that the bolt had been under torqued when it was assembled in the factory. The subframe and a dented piece of the exhaust had to be replaced. This seems very dangerous to me, especially had it occurred on an expressway at a high rate of speed.

Was sitting at light and went to take off car felt like it didn't want to shift into gear and had a loud rough grinding noise, all lights on the dashboard came one. Brake light, check engine light, coolant, etc and none of the gauges were working. I stopped at the store and went to leave the car would start up but wouldn't go into gear, it was stuck in park. I had to get it towed to the dealership to have it looked at. I had just had this same problem 1 week ago where all the lights were on and the gauges weren't working and the dealership had supposedly replaced the fuse panel box but that apparently didn't fix the problem. I think that it's a computer or engine issue.
