IONIQ Hybrid: try the reset button first
The IONIQ Hybrid and Plug-in Hybrid do not use a conventional lead-acid 12V battery under the bonnet. Their 12V supply comes from a lithium unit built into the hybrid battery pack, with a 12V BATT RESET button on the dashboard. If the car is dead, press the button and try to start within a short window. If that fails, the fault is dealer work, not a roadside swap.
