It also has never overheated
Coolant temperature gauge on dash showing wrong temperature while ECT reads correctly.
I have a 2012 malibu lt with 2.4 LE9 ecotec engine. The coolant temperature gauge on dash is showing high temperature way out of bounds. No codes and I can read the correct ect temperature via a reader.

The ac is also working fine with hot air blowing out.
So a reboot/ capacitor discharge?Disconnect the battery and hold the two leads together for 10 seconds. Re-connect and see if that helps. Maybe you need to recalibrate the instrument cluster. How that is done, I don't know.
Does this model have a second battery?Disconnect the battery and hold the two leads together for 10 seconds. Re-connect and see if that helps. Maybe you need to recalibrate the instrument cluster. How that is done, I don't know.
Okay so that didn't work. Nothing changed--the instrument cluster's gauge is still in the same position and out of bound. Also I should mention that the instrument cluster's hand does thing where when you plug in and turn the key, it moves as "normal". And then it get stuck on the fuel cluster lol.Disconnect the battery and hold the two leads together for 10 seconds. Re-connect and see if that helps.
