So, I looked into it and found out it was the Coolant Bypass Valve, and asked the dealership about it and they said 700 dollars to replace. I did not want to pay that much especially since I saw online others were having the same problem. Message still pops up to this day when I turn on my A/C. Car now has around 205,000 miles on it and is six years old.
