2021 GMC ACADIA Complaints

"STEERING ASSIST REDUCED. DRIVE WITH CARE" message, fan runs nonstop, even after the vehicle is off. Sounds like a plane taking off. This seems to be EXTREMELY common after doing my research. Please consider turning this into a recall!

For the 3rd time of ownership the cooling fan stays on after vehicle is turned off and the display “steering assist is reduced, drive with caution”.

The thermostat failed which cause the steering system to fail and car to not read temperature

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

ABS Modulator failed leaking oil. Loss of braking Repair service found the same problem. Part was scrapped.

Often times, on the heads-up display I would get "Steering Assist is Reduced Drive with Care" and my temp gauge will stop working and when I stop, my fan continues to run until I disconnect the battery for 20 secs.

Transmission feels like it’s slipping, almost like a jerky shift from any stop, seems like a common issue and should be recalled!

I was driving home and about 10 minutes into my drive I got a notification about my steering assistance being disabled. When I arrived home about 10 minutes or so later and went to shut my car off I noticed that a very loud fan sound from the hood of my vehicle began roaring. I restarted my car and it went away. I looked at my temperature gauge and it was all the way on C. I tried shutting my car off again and the loud electrical fan sound picked right back up again. I stayed in my vehicle while it was turned off waiting to see if it would stop while trying to call for answers. I couldn’t risk having a dead battery for work tomorrow morning. After what was about 6-7 minutes the electrical fan finally shut off. Turns out my aunt JUST had this exact same issue with her 2021 GMC Acadia as well. According to Reddit MANY people are having this issue yet there is still no recall for this problem. My car is only at 85K miles, has always been dealership maintained and has never had any issues like this until now. If this is a wide spread make and model issue a recall should have been issued.
