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.

Back in June 2025 my car started having an issue with the auto on/off light blinking on the dash and unable to be turned off. While driving and this happens, the car is unable to maintain its sped or accelerate. This has caused safety concerns many times. Dyer Kia first said it was an update, problem still remained. Then they said a deeper update was needed to no avail. The third attempt was a new transmission which caused more problems and still did not address the initial issue. Then they said it was the battery. They installed/ replaced an already new battery yet the problem still existed. Another transmission was put in and the problem still existed. Then they replaced the TCM and the issue still exists. The car is at a new dealership and already they are saying they have not found any codes to explain the problem yet and that they need to repair the battery terminal leads that the previous dealership broke before they are able to go further. Kia corporate is not helping me find a permanent solution to this issue and I still do not have my vehicle.

My car will sometimes completely stall at a light when stopped and not restart with the Automatic stop system it has happened about 5 times almost causing a wreck.

Electrical issue all dash lights came on and couldn’t shift into gear, had to replace my main computer as it was fried at 72,000 miles, also had to get the steering column replaced total of $6,000 fixes

The vehicle is hesitant during acceleration and linger in one gear. when try to move from a stop have to remove foot of the gas and back again with a pause before it will accelerate, only to start jerking.

Recall SA512 was previously completed on my vehicle. The problem is happening again. Since there are no open recalls, I am unable to get it fixed under the recall.
