Vehicle may not have a successful 2nd remote start if customer happens to request it immediately after 1st remote start without letting the vehicle sleep while at low High Voltage \(HV\) battery State of Charge \(SOC\). Vehicle may not achieve propulsion through a cold key crank if the HV battery was not conditioned using thermal periodic wakeup featur
