Two issues; the similarly reported electrical stop. Started car on cold morning, drove short distance, dropped kids off at school. Went to restart, and car was completely dead. Had to jump it. Second issue; burning oil smell in cabin. Oil level was fine, and smell not coming from tail pipe. Took car to shop today for the oil smell, and I told them about the electrical stop. They said the electrical issue is related to needing to replace 4 relays. The oil smell, however, is due to a bad crankcase seal that they said failed most likely due to the cold.
