I continue to get a message "Steering assist is reduced drive with care " this appears to be a very common issue with my vehicle model. it is very expensive to fix.

POWER TRAIN, ENGINE, STEERING
When I’m driving a warning comes on my DIC screen that says “ACTION REQUIRED STEERING ASSIST IS REDUCED DRIVE WITH CARE”. The AC does not work and the temp gauge goes to cold with the radiator fan blowing at full speed. My car has done this since I purchased it used in 2019 and when I call dealer they say there is no recall and $1200-1800 to replace a sensor and thermostate. I have not had the issue fixed yet.

ELECTRICAL SYSTEM, ENGINE
Multiple times an alert has been given for "Driver assist temporarily reduced, drive cautiously". Additionally, the check engine light has come on, with codes for the cooling system. Cooling system fan (HVAC Blower) remains on after shutting off vehicle for anywhere from 5-15 minutes. Coolant levels have been checked and are correct. Heat & AC function, however the thermostat gauge on the instrument panel does not read any temperature at all. At this time, the vehicle has not been taken to the dealership for assessment due to financial constraints.

ELECTRICAL SYSTEM
When parking the vehicle the electrical system will put a warning on the dash indicating you are not in park. A message indicates shift to park. The car will not shut off and you cannot lock the vehicle. This happened when I first bought the vehicle and it was under warranty and repaired. It is now happening a second time in 2025.

ENGINE, STEERING
The "Steering Assist is Reduced" warning came on the same time the engine thermostat display stopped working. Then the check engine light came on the same time the AC stopped working. At first I thought maybe it was just the battery, so I had that changed out. But the "Steering Assist" warning continued and the engine thermostat display was still stuck on "Cold" no matter what (note: the oil temp display still worked fine). Looking in to the problem, apparently a defective Engine Thermostat is a pretty common issue with this vehicle. Why isn't there already a recall on this? The risk of engine overheating is HUGE and dangerous. I called GMC and they want to charge and arm and a leg to fix it (the car has 47000 miles so is just out of warranty). I don't want to wait until there is an accident to have something done about this.

AIR BAGS
I purchased a used 2019 GMC Acadia from Grieco Honda around November 20, 2023. They showed me a CarFax report indicating the vehicle had never been in an accident. Immediately after the purchase, I reported several issues and attempted to return the car under their 30-day warranty. However, the salesperson convinced me not to return it, assuring me that they would address all of the problems. From the beginning, I complained that the car shook violently when driving between 45–60 mph, especially during acceleration. The vehicle took an unusually long time to heat up, and the brakes were loud and squeaky. A few months later, after driving over a large speed bump, the airbag warning light turned on. During my next oil change, I mentioned this issue, along with a problem with the window sensor. They dismissed my concerns and told me to take the car to GMC across the street because they lacked the tools to diagnose it. At GMC Hurd, I was told the diagnostic service would cost $160 and that I would need to leave the vehicle for the day. At the time, I couldn’t leave the car because I needed it to pick up my children. Now, in November 2025, my inspection is due. I brought the car back to GMC, and they informed me that the vehicle had been in a major accident prior to my ownership. They discovered that the airbags had previously deployed and were stuffed back into the driver’s seat and sewn shut. I have never been in an accident with this car. I reported this to Grieco since they were the ones who inspected the vehicle in November 2023 and passed it. I believe they managed to get the car through inspection without properly or thoroughly examining it before selling it to me. They have dismissed my concerns and told me there is nothing they can do. This is outrageous, as the airbags would not have deployed in an emergency, putting my safety at serious risk.

STEERING
"STEERING ASSIST IS REDUCED" This message appears on the instrument panel once in a while, and I have to get a mechanic to reset it. Many other people who drive the 2018 GMC Acadia, are reporting the same problem. This occurs so frequently on this model, that it obviously was a manufacturing design flaw.

ELECTRICAL SYSTEM
When DRIVING the center console screen begins to glitch. It will begin to move around and try to connect to the internet, begin to track navigation, connect to my phone and make calls, or it will just started moving back and forth from the different screens. It also makes sounds while it is glitching. It's incredibly distracting when I am trying to drive. There are a number of online forums that have identified the problem in their same year, make, and model of vehicle. There were no warnings or messages prior to the problem. It presented itself about a year ago and I have just been resetting the battery as a temporary solution.

GM need to be looked at for faulty Thermostats being put into vehicles. While driving the message "steering assist is reduced " You get to a safe place and shut you car off and the fan still runs. After speaking with my dealer today, he said he has done 7 in last week. And if you look online, everyone especially Acadia models is having this problem. Customers are getting charged alot of money for the repair. To me this is a defective thermostat on GM and needs to be addressed
