Hi im kevin the most common cause of this issue is the auxilliary battery voltage dropping low .aaa should be able to get you started with a battery pack if this is the case and a replacement 12 volt battery will be needed

Tnx. My husband had to use regular unleaded instead of premium. Could this have been related? The car was running fine when we pulled into the gas station 15 min ago.

Will make no difference as the car has no way of telling what fuel youve added and if fuel were to cause any issues it would only be once engine is running .i believe your battery voltage is low
