I have a 2019 kia optima LX 2.4L with 10000 miles on it. I bought it with 6000 and ever since I bought it, it has had this issue. It doesn't happen all the time but when I accelerate, it feels like it misfires or isn't getting enough fuel. It does it at low rpm's, high rpm's, and even when I have the cruise set at 80. It has also shut off on me 4 or 5 times. Each time was at a stop. Once had to give it gas when I started back up so it wouldn't die right back out. No CEL and when I take it to KIA, they say they can't do anything because they can't duplicate it. Anyone have similar issues or know a solution?
