What owners say
I was driving on a busy road when the computer system completely stopped the engine from running and gave a message/notice appear, accompanied with an alarm stating "engine failure." I had to put the car in neutral and try to pull over to safety. This is the third time this has happened. The second time, the dealer repair shop ran a diagnostic test and told me that they reset the computer, and nothing was wrong mechanically. This time, it is sitting at the dealership waiting to have a diagnostic test done, but I was told it was likely just a computer issue. Prior to the engine being completely stopped, the car will jump gears while driving [i.e., from 1st to 5th while going 25 miles an hour and not accelerating], and the car feels like it is misfiring. The car is two years old and has 50,000 miles. It should not have any of these issues. A car should not be putting my life in danger while driving for no reason and without any effort to fix it.
The vehicle began misfiring while driving on the highway. The check engine light turned on. The vehicle shook violently when the gas pedal was pressed. The vehicle was unable to accelerate and required the driver to pull over on the side of the highway. This issue has presented itself several times since the original incident. After multiple visits to the dealer, the issue has NOT been resolved. The check engine light has been caused by code P0301 (misfire cylinder 1) as well as P0304 (misfire cylinder 4). Spark plugs and ignition coils have been replaced by the dealer, but the issue still persists. Forcing the vehicle to pull over and being unable to accelerate on the highway is risk to the driver's safety as well as the safety of other vehicles on the road. The vehicle also now struggles to start and begins misfiring when left off overnight and started cold.
This is the second occurrence of this issue. Suddenly all warning lights appear and the car loses power. When press the accelerator there is no revs increase and the engine misfires. I photographed the dashboard and will try to attach. The car becomes impossible to drive and my wife is scared to use it. Luckily in both cases I have been able to stop in a safe area. Switching off and restarting the engine a couple of times re-established normal engine running the issue but left the ECU warning light on.

Have contacted dealership as well as corporate kia and have not been able to get any resolution. this issue apperaed first with a check engine light Sep 2022 ,
