I drove my vehicle listed above CXL model to the gas station and it drove fine, started right up. Next morning I went out to start it, and nothing besides all the lights would come on and it made a clicking sound. Replaced the battery, starter, MAP sensor, and checked/replaced all the fuses. My car still won't crank...

You might have a blown head gasket that has filled one of the cylinders with coolant. Here is a video you can try to see if the engine rotates by hand. Also, you can remove the spark plugs to see if that makes a change.

I have seen the positive battery cable go out and cause this issue, as well. So, if the engine does rotate, I would check there next. You can confirm the cable by putting a test light on the positive cable by the starter to see if it goes out or dims when in the crank position. Here is a video that can help as well:
