My car is a 19 sonata. When I'm done driving I'll open the door and the car starts beeping like I have my lights on or something. With this, the car refuses to lock when pressing the lock on the door, or manually pushing them in. Also when this occurs my fob will suddenly not function at all. The only fix I've found is to start the car up and change the user settings for automatic door unlocking. Even with the auto unlocking fully disabled I still have this issue randomly.
