In general, it should. You could have a draw or short somewhere that is causing the battery to drain. I've definitely seen Cadillac's with draws that kill a battery over a shorter span of time. Ultimately, the manufacturer should have a draw chart that shows the acceptable / expected draw with the key off and all accessories off. If you have a multi-meter, you should be able to do more in depth testing without needing to pay a mechanic or dealer. I'm adding a link that you can copy & paste that has someone experiencing similar issues. https://www.cnet.com/forums/discussions/hyundai-sonata-battery-drain-mystery/
