Did you even bother to read the first post? Coolant that is returned to the holding reservoir is so hot, it's boiling over? He already took the car to the dealer, and replaced just about the entire system.....

As a shop owner, one thing I must ALWAYS remember: New does not mean good. I have had bad stuff right out of the box.
Now, throwing parts at a car is not always the best way to go. In this case, items are cheap, so why not. If you are out of ideas, take it to a GOOD shop for proper diagnosis. Yes, it will cost money. So does buying a bunch of parts that dont fix the issue. But the frustration, and the doubt will be gone afterwards. Yes, I know you already did that. This is not a wiring gremlin. This is a physical thing to track down. Whoever looked at it HAD to have been slightly lacking in details.
A parts store OBDII reader will not likely give datastream information to determine what the coolant temp is. They "specialize" in code reading, not diagnosing. There is a difference.

I drove it to work this morning with no problems, yesterday didnt make it to work before the coolant started overflowing. Checked it in the parking lot when I got to work and didnt seem to be hot at all. As far as the fan goes it would work before but only seemed to work when the A/C was on and didnt seem to come on very often at all. Now it seems to be coming on more frequently and comes on when the A/C is turned off.

Changed the temp sensor, turned the car back on and the fan kicked on within a min. Fan seems to me working more frequently now. the tip of the sensor was black not sure if that means anything. Drove it around tonight with no problems we'll see what tomorrow has in store.
I changed the relays with no love. Intermittent fan operation same as above.
Help

Open the cap while the engine is cold. Let it warm up and turn the heat to full, then watch for bubbles. I replaced my coolant reservoir because it was leaking some but not much which was causing to peel the underneath of my hood. If it's not indicating that it's overheating then change the temp sensor.
