No more problems since my thermostat was changed.
No more problems since my thermostat was changed.Was issue fixed after the new thermostat?
I had the same issue. I took it to my dealer, they are going to replace the whole thermostat box. He said it was a common issue and it is covered under my powertrain warranty. Only problem is that the product is 1-2 weeks out.I am having this issue now with my 2019 Acadia. Were you able to get the issue resolved?
According to my dealer this should be covered under the powertrain warranty. Mine is at the dealer right now getting fixed.I just replaced the battery and still am having this error message. I have a 2018 Acadia. Did they give you an estimate for the thermostat?
i had the same problem and it is the thermostatI have a 2018 Acadia Denali & it is showing the Steering Assist Error Message which I believe is something with the Thermostat. Can someone please quickly explain the cause of this problem & what the Solution is? I want to be able to present it to the dealer if they try and tell me the problem I'm having is something else. Thank you, Dan
The problem will likely return.Can’t believe that was it! 2019 Acadia SLT2 and exact same problem out of nowhere: “Steering Assist is Reduced Drive with Care”, and at the same time the AC started blowing with no cold air at all- (it went to full power without touching it.) Cleaned the terminals, including fuse terminals on top of battery. Waited 15 mins and everything worked perfectly fine.
Ok can some one please tell use where the thermostat is located in a2018. My husband has always worked on our cars. But we can not find a Haynes book on this car. It seems they don’t make it past the 2017. If he could locate it could change it out.i had the same problem and it is the thermostat
Haynes manuals have become pretty much worthless on modern vehicles. You need either a copy of the factory service manual or a subscription to ALLDATA.comOk can some one please tell use where the thermostat is located in a2018.

I had to unseat the ground on the battery and reseat (reset the system) - Problems resolved.
Generally, this condition occurs because the thermostat may stick - - -OPEN . .. . so the engine control computer see it as not getting to a warm enough temperature in a certain amount of time.Hi All,
I have same issue on my 2017 Acadia Denali , current odometer 112,891 kms / 70,147 miles.
Took it to local GMC Dealer Service centre. They are saying is a "big" job with 6 hours of work required.
They are saying the "Thermostat is stuck" and is blocking the engine coolant from flowing correctly through engine.
And due to the location of thermostat box, it will require them 6 hours to replace and they will also need to flush out and refill engine coolant. They mentioned that I was lucky that I didn't drive a lot with this condition as there was possibility of engine overheating and possibly blowing up.
Wanted to check if C$2250.00 + tax , seems genuine for this job?
I am reading folks talking about $1400 out-the-door, thats like $1866 CAD.
This is GMC dealership located in Coquitlam, BC, CANADA.
Is it valid explanation that engine could overheat due to this issue?
I read through this thread and no where anyone has talked about engine overheating. I took my car to dealership right after warning message came, so not sure if engine is heating due to this.
Thank you for saving my life! I've had this issue for 2 years and couldn't figure it out.Had the same problem back in June and before message would come on then go off then it came on consistently air conditioner shut down. Research the issue tried a few fixes the one I found at work or my problem was the battery terminals need to be cleaned and tightened. Once that was done the problem was fixed so far the last three months have been good.
