2022 Hyundai Sonata Electrical System

Initially vehicle battery is drained after three days of sitting in driveway and not being used. Vehicle has been taken in to dealership in July 2025 and found the 12v integrated battery was faulty and was replaced after being on backorder for three weeks. After battery was replaced the vehicle battery is drained after five days of sitting in driveway and not being used. No lights are left on, no aftermarket accessories are plugged in or attached to the electrical system. This has been an ongoing issue and the dealership I initially worked with has now had my car 3 different times and over four weeks and have stopped returning my phone calls. I have just sent my car do a different dealership and have been told it may take up to 2 months to diagnose the issue. I cannot open the door or start the car without using the emergency key, when I gain access to the car the 12v battery reset button rarely works to power the vehicle again. This is something that the dealerships are aware of, but have no idea what the actual problem is. Please for the love of God help.

Went to lower the AC fan speed earlier then went to turn it back on and the whole blower stopped working.

The car will not lock, the signal lights do not function, I cannot open gas door, cannot unlock trunk. I took the care to the service center and they just told me it was the junction box. I saw there was a major recall to this same car for this same problem with 2016. If this is a manufacture issue I think it should be covered by warranty but they are refusing to fix without me filing an insurance claim. My car has been inoperable since June. The hazard lights are on and I cannot operate the vehicle safely without repair of the junction box per service center at Hyundai of Greenville Sc

Trying to return home(alabama) from Louisiana, I tried using my key fob to get in my car, key fob was not working so I replaced the battery, still not working. Finally was able to get in my car by using the key, only to open the door and had NO POWER to my car, no dash or interior lights. Had to car road side service, they jumped the car off long enough to get the car in neutral to get it on the tow truck and towed to the dealership. Now stuck out of state until the dealership can "get time" to look at my car. This is a brand new car and really didn't expect this but again no matter if it is just a battery issue or something else, Hyundai's car has let me down and left me stranded. This is a huge problem especially when I need to get back home to family and my job so I can pay for this car.
