2017 Kia Optima starting issues
When I press the start button the car starts but it sounds like some of the cylinders are misfiring and the engine runs very rough, shaky, and sounds weak.
I press the start button to turn off the car, then press it again to start it and then it runs normally.
I first noticed this 2 years ago when it would happen once in a few months, now it's happening much more frequently, 2-3x a week.
Any ideas how to diagnose this and where to go to get it fixed other than the dealership (I don't trust them because in my last visit for a software recall they told me that my oil plug was leaking, where it was not).
