Check Engine Light came on with message of "Steering Assist is Reduced Drive with Care". This same thing happened to my sister-in-laws 2019 Acadia 2 months earlier. Took it in right away to the dealership to find out it's the thermostat, it's a common/known issue and it isn't covered under my extended warranty and will cost ~$1300. I'm seeing this is a common issue for Acadia's and has not had a recall, don't understand why. It's one thing if this is a easy part to replace, but GM has made it so that most people now need a dealership or auto repair shop to fix it.
Shift to Park message comes up and vehicle will not turn off. This happens frequently and so far I have been able to get it to shift into park by clicking the lever on the shifter multiple times.
Thermostat fails. Steering assist reduced message comes up on dash. Temperature gauge stops working, air conditioning stops working and engine fans run constantly when vehicle is running. I had the dealership fix and replace under warranty the first time and now it happened again a second time.
The steering assist message comes on and off whenever the weather gets cold in the fall and winter. This causes my air conditioning and/or heater to not work. I have done research and the temperature sensor needs to get replaced because there is a malfunction of the temperature not reading the coolant. Everything is fine with fl…

The steering assist message comes on and off whenever the weather gets cold in the fall and winter. This causes my air conditioning and/or heater to not work. I have done research and the temperature sensor needs to get replaced because there is a malfunction of the temperature not reading the coolant. Everything is fine with fluids and driving. This happened when I turned on the heater.
I'm going to have to replace my thermostat and most likely my sensor. It will pop up saying (steering assist is reduced drive with care) my temperature gage on my dash will sometimes will not go up, my heat is acting funny. I've had also when I put it in park saying it's not actually shifted into park.
Thermostat stuck open and a steering assist light came on engine temp needle at zero. Check engine light came on, Had to have thermostat and coolant engine temp sensor replaced
SHIFT INTO PARK ALERT AFTER CAR IS IN PARK
Thermostat is repeatedly going bad. Throws Steering Assist reduced. Had it replaced twice and it’s bad again.
I bought a car about 2 months ago and they did not tell me the thermostat was bad and they won’t cover it.
