    The panoramic sun roof opens but will not close. it takes 6-12 attempts to get it to close, it will move to where its an inch away from closing then reopen. Kia has recalls for this make and year but says my car is not affected. attempting to get it to close is very distracting and frustrating taking focus away from driving.

    The stop go feature is not working correctly, when it does cut off at a light after releasing the brake to move forward it takes 3-5 seconds to start. when the cars behind me see that i release the brake they assume im going to move which doesnt happen at first. some occasions the stop n go just doesnt work at all.

    On three separate occasions, after starting the vehicle, the car cannot be accelerated above 30 mph. The Idle Stop and Go (ISG or Auto Start Stop feature) light flashes orange, but no other warning symbols are illuminated. After safely moving the vehicle off the road, I have to turn off the engine, wait for 2-4 seconds, and restart the engine. Once the vehicle is restarted, the vehicle accelerates normally. This issue has happened twice in the past month. I plan to take my car to a Kia dealership for an inspection, but since this problem happens randomly, the Kia technicians may not be able to reproduce the problem. I purchased this vehicle used with about 77k miles in December 2023. I first noticed this issue in April 2024. The vehicle now has a little under 98k miles recorded.

    When pressing the accelerator pedal after a near stop (rolling stop, California stop, stop to u der 3mpg and then resume acceleration) or very brief stop (<1 second) there is a significant delay in acceleration or a very brief acceleration then dead pedal and no acceleration for ~ 1 second. No accelerator pedal input variations changes this, i.e. I can release the accelerator pedal, hold the accelerator pedal pr push the accelerator pedal to the floor and it’s still a “dead pedal” scenario until the car decides it’s time to go. Owned car since new (~20 miles) and now has ~64k miles, been a persistent issue for entire ownership.

    The check engine light has come on. The vehicle has stalled or loss power while driving 3 times with the last week. Once at 70 mph and the other 2 at 35 mph. Still very concerning on how to control when this occurs!!
