Last week, the coolant gauge , on our 2019 GMC Acadia, was reading below "c". . . . The "steering assist" warning was disabled on the on-screen display and the air conditioning stopped working. Took the car to a mechanic, who read the codes. . . . Mechanic stated that all symptoms were based on a defective gm thermostat. The thermostat was "stuck-open" causing the "steering assist" to be disabled as well as the a/c from being disabled as well. It seems gm has updated the part since when the series of Acadia were manufactured. After getting it repaired, at of our pockets, we researched and noticed that thousands of other gm Acadia owners had the same exact 3 symptoms: (1) malfunctioning coolant reading (2) "steering assist" disabled (3) a defective ("stuck-open") thermostat. . . . . Symptoms were exactly the same for all parties involved. We have owned many vehicles never had a thermostat fail before 65k miles. . . . It became a safety issue since the car disables the "steering assist" based on the thermostat being stuck open. Contacted gm corporate which stated unless a recall, there would be no compensation. Gm needs to make it right for the thousands of gm owners whose car has the 3. 6l engine in short, this is a major issue since the car's steering system is not working correctly we would like a recall to be initiated. Thank you.

Battery saver ignited comes on and and the entire dash flickers and turns off ! this happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! and we don’t know where it is coming from . Now shift into part light comes on !.

Car driven off the lot 06/14/2025 on Sunday 07/06/25 (21 days from purchase) while driving home from a 30 minutes away from home trip with 3 young children with me, the car gave multiple alerts and service warnings. "service brake assist" and "service ecs" lights / symbols related to the following were also displayed: traction control system (tcs)/ electronic control stability light, anti-lock brakey system (abs); brake system warning light, forward collision alert and break light I stopped the car immediately and pulled to the side of the road. After restarting vehicle, lights were still displayed and service alerts still on. Power steering was very diminished and the breaks were struggle to break. Acceleration was also impacted and every time I breaked it appeared as though the car was trying to accelerate. I was able to drive the car home slowly following back roads. On Monday 07/07/25 I called the dealership and arranged a tow to their facility. On Tuesday 07/08/25 after multiple "unavailable to take your calls" I was finally able to connect with a service technician who indicated the break master cylinder needed to be replaced. I was not given an eta on the completion of this repair. I have owned the car for 21 days. It has 1073 miles on it!!! I have 3 young children! the original route home was via a very heavy interstate! what if the brakes failed me while driving an interstate! I praise god I was able to get home safely with my children.

About a month ago when I shifted my vehicle into park and shut the vehicle off, "shift to park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "shift to park" appearing. On 7/11/25, arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off. When I went to leave for lunch, the car would not start at all, check the gm app and it stated "critically low battery". A CO-worker helped jump the battery and I was able to start the vehicle. When I went to leave work for the day, the vehicle would not start again with no notification as to why. My CO-worker jumped the battery again and vehicle started now with all the system lights on dash staying on and warnings displayed. 7/12/25 vehicle struggled to start and all system lights were still on. Later in the day, the vehicle would not start and all overhead, dash, display, taillights would not shut off. We jumped the battery and took the vehicle to our local dealer.

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.

Im a travel nurse and I was working in vermont. As I was driving on the highway in new york on my way back home a shift to park light came on, a stabilitrak light came on, power steering light came on, abs light came on, and my check engine light also came on. My vehicle started slowing down as I was driving and my lights on my dashboard were turning on and off and my speedometer was not working. I was able to pull to the side off the highway so I could get out of harms way. I made a call to onstar for help and they asked to if I made it to a safe location. As the car was still on I was able to take the next exit and ended up in an auto zone parking lot. As I made it in the parking lot I turned the vehicle off but only the engine turned off but everything else stayed on and the shift to park light kept coming on when the vehicle was in park. I was in the parking lot for 3-4 hours freezing in my vehicle until onstar came to tow my vehicle. By the time onstar came my battery in my car had drained and it was a new battery. I was told that I would have to contact auto transport to transport my vehicle to louisiana at the dealership where the vehicle was purchased. I paid $1600 to transport my vehicle back home and I had to find a way to make it back to louisiana. I didn’t have a credit card so a friend of mine was able to rent me a vehicle to get home and I paid a total of $1700 on a rental because the dealership in louisiana couldn’t give me a time or date the vehicle would have been finished. I have been to the dealership 3 times now for the same problem in less than a week. I have paid $1500 altogether to fix damages on my car that I noticed other vehicles with the same make and model had the same issues. I never had a problem with my vehicle before everything just started happening all at once. I’m currently having to pay for car rentals to get to and from work and to make sure my kids get back and forth to school. My vehicle in at the dealership again for the 3rd t.

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.

Steering assist is reduced drive with care. Everyone is have a problem with the 2018-GMC-acadia thermostat is bad.

" steering assistant reduced, drive care" " power steering ,drive with care". My car has been properly maintained, and has no issues, but this messages that keep coming up out of nowhere. And when it comes out my steering wheel gets very hard and stiff, causing me to almost get in accident in highway. This is definitely a factory defect that needs to be recalled and taken care of.

I purchased my 2023 arcadia ffwd slt a few months ago used with 11,000 miles. During the past few months I have noticed when reaching a speed of 45-60 mph the vehicle vibrates. I took the vehicle to the dealership on 10-10-24 and they said they could not find anything but they did not do an intensive problem search. I am concerned the problem may be related to a transmission recall dated 6/23. I did a search but no recalls came up my VIN but the vehicle has a major vibration when going 45-60 mph.

Went back to dealership so that they can fix it. Diagnostic code : p0128. They were able to have a/c working when I left the shop. And no messages on the instrument cluster. Following day, I have all the same issues I have before. My appointment to come back in to the shop to fix the thermostat issue I was October 10, 2024, on October 9, additional problems occur on top of the issue I am having. While driving and accelerating multiple lights on the instrument cluster screen appears on top of other issues and car decelerates.

Last week I parked in a large public parking lot and attempted to turn my car off. I received a notification in my dash to “shift to park” even though my car was already in park. I was unable to turn the car off or lock the doors. I ended up having to leave. I have now gotten this message six times in the past week. It can take up to twenty minutes to get the car to turn off so I can exit. Yesterday upon returning to the car I showed an error message as soon as I started it that the parking brake needed service, stabilitrak is disabled and steering assist is disabled- drive with care. As I tried to exit the parking lot, I found it almost impossible to turn the steering week. I pulled over and restarted the car, releasing the steering wheel so I could get home. This morning, all of the service lights were on and periodic warnings flashed on my dash throughout my drive to work. I contacted the dealership and was told that there is a recall for this exact issue on the 2015-2018 models of my car. I have a 2019. This is certainly a dangerous issue that should be proactively fixed and is clearly still present in years that are not being included in the recall. I was told my car was one month past its warranty and told I could pay 250$ for the issue to be assessed and then they could quote me on a fix. The dealership acknowledged that this is an issue they regularly fix.

On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 mhp zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a recall 17v516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.

When attempting to park vehicle, the alert "shift to park" populates and the car will not completely shut down. This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off. If it's not in the proper park position, the car can continue running, battery drainage and possible roll out of place. This also causes issues with the transmission not shutting off. I have not had this particular vehicle inspected, but contact with dealer service departments confirms continued complaints of this issue and it has not been addressed by GMC/general motors. Problem has been occurring at various times over last 3 years.

I purchased this car in may 2024 and it has done this since the day I bought it. When I shift into park and turn the car off it alerts me that I need to shift into park but it already is, I have to squeeze/jiggle the button on the shifter to make it stop. I feel this could cause some serious problems.

Complete loss of steering at low speeds. This has been an issue with gm for years, and is still not corrected on my 2015 GMC Acadia. At a stop light or when turning a corner, I could barely turn the steering wheel. Gm needs to pay to have this fixed on all vehicles still affected. There is no way I could maneuver this vehicle to avoid a person or vehicle.

Steering assist is reduced due to a faulty thermostat.

All of this has been going on for a while but it's gotten to the point of dangerous. The shift to park keeps coming on preventing me from shutting the vehicle off even though it's, in fact, in park. Then, "steering assist reduced drive with care" keeps coming on. This will come on and off. Preventing the engine from heating up like it needs to be. Then the transmission keeps slipping. Was nearly rear-ended on the highway with my child in the car when it decided to start driving really rough and wouldn't allow me to shift to the next gear. This is also an ongoing issue. Another time I was almost hit in the side when this randomly happened on crossing the highway. This is absolutely absurd! I have had much older vehicles without all these issues with many many more miles! I can't count the amount of times this has caused us serious hazards not to mention almost costing me my job! interestingly enough, the same year/make/model has been recalled for the exact same issues yet for whatever reason GMC says my model "was not affected by the recall". Funny how it's having the exact same issues as the ones on the recall list! GMC needs to fix this before they cause people to die! I'm a healthcare worker and this is disgusting!.

About 1 month ago while making a slow speed turn from a parking lot to a street the steering seemed to lock for no reason. After a brief moment the steering resumed normal function. I inspected the ignition switch and found nothing abnormal. Checked power steering fluid level, it was in the operating range. Unable to duplicate the issue at that time. On 3-9-23 while driving the vehicle started making an unusual noise coming from the engine. It seemed to be consistent with engine rpm. I believe it was the power steering pump. After stopping and starting the engine the noise was gone. A few minutes later while driving at slow speed the steering locked again, or the resistance was too great for my wife to overcome.

The contact owns a 2015 GMC Acadia. The contact stated while making a turn and parking, the steering wheel was hard to maneuver. The contact stated no warning lights illuminated. The contact drove the vehicle to an independent mechanic who diagnosed that the power pump steering needed to be replaced as there were metal shavings found in the fluid. The vehicle was at the independent mechanic awaiting a power steering pump. The manufacturer was not notified of the failure. The approximate failure mileage was 43,000.

Rack and pinion sudden failure. I lost control of the vehicle almost going off the road .

Not inspected by anyone else because they have no idea where to look because the light and actions happen on and off. Warning light and message appears. Service traction control and service stabilink light yes I will bring it in. It will turn on randomly at this point for about 4 months and the brakes are locking up the wheels while driving.

The rack unit is going out. It makes the vehicle suddenly jerk to the left at highway speeds. It could cause a collision if there is a car on the left or a head on collision if on a two lane road. It also increases the amount of force needed to steer at low speeds. I took to the mechanic and was told that it needed to be replaced and would be 2500+ dollars to repair it and that they could not do the repair their only recommendation was to take it to the dealer. So gm is not wanting to issue a recall because it would cost them a lot of money to fix it.
