Lost all power, and into the shop it went

I went to start my car after it sat in a parking lot all day, to find it was misfiring so badly I couldn't back it up more than a few feet. I had it towed to a shop, who says that they have DTC's for random misfiring and a failed crank sensor, it's overheating, and it was low on both coolant and oil.

I can vouch that the oil dipstick showed full two days prior, nor was there oil in my parking spaces. The engine had been occasionally running on the warm side (225F) due to the summer heat, but had never overheated, though I had the thermostat replaced when it stuck open during the winter.

What do you think happened? They found a new-to-me oil leak under the engine somewhere. Except for the crank sensor code, I'd say the head gaskets blowing would explain everything else.

Has anyone had a similar problem with their G6?
