OK, Does the engine run but the Jeep will not move or is sluggish when put in gear? From the description of it revving to 6K but no motion that isn't the engine, that is the typical failure mode of the CVT transmission in the Patriot.
It sounds like you need to have a scan done to see what the code(s) that turned on the light are first. That will give you a starting point.
I hope I am wrong on the transmission, but they are very failure prone.
