We have a little over 700 miles on our 2019 Kia Optima LX with the 2.4 engine. Has Kia figured out why the engines were failing? Anyone with a 2019 have engine problems? Only issue we had was the horn started honking when my wife opened the door to get out to do some shopping. A lady came by and told her to press the close door then open door on her key fob and it stopped the honking. Other than that, all is well.

On her Ford, she would put her key in the ignition and turn on the engine to stop the honking. On her Kia, the engine would not start with the key, so she was lucky the lady came by with the solution to the problem.
