I have a 2013 Impala with the 3.6l with 96xxx miles. At random I am receiving a dash fault of Engine Hot A/C off, temp gauge drops below C ( like when the key is off or the sensor is disconnected ) cooling fans ramp up to full speed and stay on after shutdown and key is removed. It is also starting to show and log a active fault code ( will have to get back with the code id# ) and this will all reset or clear with battery disconnected. I have seen in othe forums that the recommendation for repair is the CTS replacement as well as the thermostat. Both of these have been replaced and I still receiving the same code. Any ideas beyond these two repair options?
