I just bought a used 2023 Kia Carnival with only 7000 klm on it. The next day the engine light came on with P0300 code: Random/Multiple Cylinder Misfire Detected. The night before my kids were playing with the remote start, and turned the car on and off multiple times. Could this have caused this code?

I cleared the code and it has not come back after a week of driving. The car is still under warranty. Should I take it in to the dealership to have it looked at?
