2024 Hyundai Kona ELECTRICAL SYSTEM,ENGINE

A few different days over the past few months. Driving heated seats stopped working. Check engine warning light on intermittently. Key fob not working. Multiple error codes stored in system cleared by dealer. shut down the car screen has stayed on. AC light has stayed on when car is off. Screen has turned off “check you back seat” upon leaving the car heard the engine still on 3x. At the gas station turned off the car, miles to zero reading 5, P park stays on, odometer reading on. As tank filling miles to zero rapidly increased from 5 to 300. I have a video of this. Been in for service multiple times. Presently at the dealer. They r unable to replicate this. They do not seem concerned about this. I feel it is a safety and operational concern. Prefer by car not be communicating even with itself while I’m pumping gas. They want me to pick up the car. I do not wish to. I have asked if miles to zero reading is supposed to increase real time I would like to see this is the manual or other documentation. Otherwise I feel it is a huge safety risk to have my car not shut down when I ask it to. What’s to say it won’t shut down while I’m driving 75mph on the freeway? Thank you

Car will restart after it is turned off and left for awhile. Transmission will jerk hard while in gear and driving.

Twice my car wouldn't come on at all. The first time they put a new battery in even though I had it only 2 weeks and it's a 2024. The second time was today. The engine would not come on. My inside lights were blinking but the car wouldn't start. The lights went out on the inside but when I went outside the car, my outside light were blinking real fast. This lasted for about 15 minutes and then they went dead. The whole car was dead and had to be towed to the dealership.
