My 2024 Kona sat idle for two weeks while I was in the hospital. The battery went dead and refused to hold a charge. Hyundai is denying my warranty claim due to 'aftermarket components detected'?!

[DO2. Current draw from aftermarket electronic component(s) detected. Inspect and remove any aftermarket electronic component(s). Battery sensor requires activation.]

Aftermarket electronic components constantly draw power, and rapidly reduce

 battery State of Charge (SOC).

 Charge the battery with approved charger or idle the engine with the

 headlights ON.

(To activate the battery sensor, wait 4 hours after the engine off.)

Current Battery State of Charge (SOC) : Invalid

Anyone else experience this nonsense?
