So I get into my car and the drivers door does the exact same thing. THAT ends up being the least of my worries!

I start the car to warm it up go into the house to get my daughter ready to bring to daycare. I leave the car in the driveway running for maybe 10 minutes tops. I get Bella into the car I get into the drivers seat (holding my door shut) and look at my temp gauge. IT IS PINNED TO THE RED. NO other lights are on just the temp gauge pegged. I immediately shut the car off. Now its 6am and I am questioning if I saw what I thought I saw so I restart the car. When I restart it the temp gauge is now below the 12'oclock (towards the cool side) I think Huh maybe I was seeing things. I drive (still holding my door closed) to the daycare about 4 miles from my house. I get my daughter into the daycare and leave the car running outside the daycare for about 2 minutes. I get back in and the temp gauge is normal 12 oclock. I have NO heat coming out of the vents this whole time. I start driving home and the car is very very sluggish almost no power. The temp gauge now drops back to the half point of the cool side of the gauge. I drive 4 miles home, park and call the dealer.
They are going to take the car in tomorrow. It is still THANK GOD covered under CPO. This all happened this morning. I just went out to have a look under the car and under the hood. No leaks under the car but I did notice a odd wetspot around the oil filler cap and when I took it off the inside looks like a coffee milkshake, I decided to pull the dipstick and that looks like a milkshake too. Any ideas what might be wrong with my car?

Thanks!
