Kia Telluride electrical system failure recurring after battery disconnection on Kia Telluride

Some Kia Telluride owners report experiencing recurring electrical system failures, including battery discharging issues attributed to external electrical devices. Despite disconnecting the negative battery cable, some owners find that the battery drain persists, indicating a potential underlying problem. Reports include messages stating "Battery Discharging Due To External Electrical Devices," even after removing items like USB drives and dash cams, suggesting that the issue may be more complex than just external devices. Additionally, some owners are advised to consider potential charging system issues if the battery discharge warning appears while the engine is running, as the charging system should provide sufficient power to the electrical system. It is recommended that owners have their Kia Telluride's electrical system inspected by a qualified technician to effectively diagnose and resolve these issues.
