Power train incident - • transmission holding gears, jerking between shifts, gear shifted into s mode on its own and stuck there, unresponsive acceleration, locked up steering/inability to turn the steering wheel and total loss of drive power. • happened while merging onto a highway in one of two split lanes for highway access. A merging semi truck in the other merging lane almost ran into me because I could not give it gas. Me and a local police officer who saw me broke down and stopped to provide additional cover, were nearly hit several (6) times from other vehicles and semi trucks due to malfunctions happening. • diagnosed by kia dealership and was told there was a major electrical failure which caused the electrical oil pump to fail and need a new transmission. Although my VIN doesn’t list recalls, similar issue to the recall on my same year/make/model under NHTSA campaign number 21v519. • warning lamps/messages shown in photos attached. __________________________________ forward collision warning incident - • front forward safety system light appeared on dash, then moments later a warning appeared and the vehicle braked on its own detecting a vehicle in front of me when there was not another vehicle in front of me within vision!! • happened while driving in a 55mph zone, a vehicle was driving behind me when this occurred and that vehicle almost slammed into the back end of mine causing a crash. • problem not yet inspected on vehicle due to blown transmission from above incident and inability to start/move the vehicle.

6 Warnings problem

Failure Date: 12/17/2021

I was on a straight road no cars around the collision sensor went off and slowed me down. Another time it kept slowing the passenger side wheel down as the traction control was going off it did this 2 separate times. Got down the road some and it did it 2 more times but with the driver side. Last week I pulled into my drive way and was in park when it started telling me traffic was coming from the left, like I was about to back into something, I can't remember if I had shut it off at this time due to someone had fell out of the 3rd row when her foot was caught in the seat belt trying to exit the car. I called my nearest kia dealer and was told they were so far behind and since I did not buy my vehicle from them it would be last. I asked if an accident was to happen who would be responsible and he couldn't answer me.
