## NHTSA's summary

Some customers may experience a vehicle no start \(no "Ready\-ON"\) due to the 12V battery discharged or the High Voltage \(HV\) battery discharged. This may be caused by: Ignition left ON when exiting the vehicle \(exiting the vehicle during "Ready\-On"\). Door/liftgate opened multiple times without ignition "Ready\-ON" or driving vehicle. Installation of aftermarket electronic devices. To minimize THE battery drain concern, ensure that the vehicle shift selector is in Park when exiting and verify the ignition is turned OFF when exiting. NOTE: If multiple door/liftgate opening without "Ready\-ON', drive vehicle to charge 12V battery.
