I have a 2020 Kia Sorento EX 3.3L V6 that is having intermittent misfires. It happened one time 4 weeks ago after a 3 hour drive. I stopped and got the code read and it said P306 and P305. I turned the car off and back on and the check engine light and misfires went away. 4 weeks later, after a 1.5 hour drive, the same thing happened. However this time, the light would not go away. I got a hotel and let it sit over night. The coolant was low so I replaced that. I got the code read again this time and it said misfires on 1,3,5,and 6. After the coolant was added, a short time later the light and misfires went away and haven't came back again in a week. Its still shaky when cruising (without hitting the gas) between 1 and 2 RPMs. I have passed over the 60,000 basic warranty at this point as its now at 60,600 miles.
