This Problem Across All Years
1. Shift to Park failure, P0700/P187e internal sensor, causing me to have to get a rebuilt transmission. 10/2025 2. Transmission shudder/hard-shifting ongoing 2022-2025 3. Coolant/thermostat issues. Steering Assist Reduced" message, fans stay on HIGH, no AC, engine temp on ZERO ongoing since 2024 3. Start/Stop button failure multiple times (replaced 3 times) 4. Rack and pinion/steering gear (would not return/ got stuck while turning) got new rack and pinion 2023 5. Water pump leaking, replaced 4/2024 6. Since 2023, have had ongoing “Timing OVER ADVANCED”, warning issues since 2023. This is TOO MUCH for a New car!!! I’ve owned MANY cars and NEVER had this many issues!!! There appears to be multiple design flaws with this model and similar models!

Steering Assist reduced drive with care message. This is an extremely common issue and should be a recall. ALOT of people including my dealer service advisor has this issue with their vehicle this message comes up fans kick on high a/c stops working and temp gauge stops working. It can be reset by unplugging battery or clearing the code.

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.

An error pops on the dash that says steering assist is reduced-drive with care, and the thermostat gauge does not work, nor does the air conditioner and the vehicle fan under the hood is extremely loud. This has been happening intermittently since September 2024. Basic research on the Internet is showing many people have the same issue with these vehicles. Further research suggests possible vehicle computer system issues. I don't know why there isn't a recall already.

Power steering system fails intermittently. Power steering goes and comes back on without warning, causing the driver to oversteer the vehicle. Mechanic performed software update, which did not fix the problem and told me the power steering module needs to be replaced, which would be over $1,000 for the part, plus labor and re-alignment. Additionally, the replacement power steering module is not currently available - it is on backorder.

When it rains(or car wash) my power locks don't work. I get locked out of my car. My car reset itself in the middle of an intersection(like I turned it off and back on again). One of my gauges is always not working. The sunroof doesn't work right. Water is getting in the electrical area somehow. I've taken it to two chevrolet dealerships, but no help.

My steering assist is reduced drive with care message is on. The AC is no longer working and the fan is constantly running and sounds horrible. The temperature gauge has not come off of cold. After researching this issue online-it looks like this is a constant problem with Acadias from 2017-current. People are talking about the cost being between $1100-2400 to fix. There is a service bulletin out about this issue(17-NA-158) May 2017 If GMC knows that this is a problem why are they not recalling them?? My car was purchased brand new and of course is out of warranty like most others(the extended warranty doesn’t cover it either) GMC needs to recall these vehicles and fix this issue!!!!!

While driving, the power steering went out and a service power steering message appeared. I turned off the vehicle and waited a few minutes and when the car was turned on it went away and the power steering came back.
