So, I just bought a 2011 Genesis coupe 2.0t a week ago, on my way home tonight I came to a stop sign, rolled through it and got on the gas slightly, the car jerked to about 3k rpm then dropped to 1k jerked to 3k ish again then back down, then did it once more before I let off the gas, it did it decently rapidly, I got back on the gas pedal and it was fine for the remaining 30 seconds to my house, it probably did this within a span of 5 seconds max, it is an automatic, it has 126k miles on it and definitely isn’t perfect but this is the first thing it has done in the week I have owned it. I’m sure the car was beat on before I bought it but it seems to run and drive great besides doing this, if anyone has had this issue or knows what it is and if it should be concerning please let me know.
