I have had nothing but issues with this vehicle from the day I purchased it. I should have been more leery of purchasing a vehicle with so few miles on it as a certified vehicle. First issue lift gate wouldn’t work. Had to have sensors replaced twice. Next was the purge valve sensor that has went bad 3 separate times. Then the crankcase vent sensor. Paid a fee for diagnostics, it was not repaired took it back when the engine light came back on, they replaced it without charging but I was advised it’s not covered under warranty. And most recently my check engine light came on yet again today now reading an issue with the engine cooling system. Unfortunately the dealer is so booked out, my only option is to drop it off and hope they can get it in by a cancellation or no show. Seems there are new issues ever 3-6 months with the car.

Vehicle gives, “driver assist reduced drive with care” warning randomly. Lane change will no longer work and engine light will come on. Problem is sporadic and does not stay active. Engine light will shut off after a day. Once vehicle is shut off cooling fan runs extremely loud and for a long period of time draining battery.

When vehicle is put into park I keep getting a "shift to park" message and cannot turn off my vehicle. I cannot lock the door.

After shifting to park and attempting to turn off my vehicle, I receive an “action required shift to park” error message. I’m assuming the vehicle is in park but I’m not certain and worry about it moving or rolling. It is difficult to get it to turn off by jiggling the shifter and turning the vehicle on and off. At times, I am not able to get it off and then the vehicle will not lock and the battery goes dead. According to my VIN there is not an active recall but brief internet search states there has been numerous reports, recalls, and lemon law returns due to this.

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.

Truck lost power randomly while driving on freeway spend so much money on fixing it this has to do something with the way the built it.

The contact owns a 2017 GMC Acadia. The contact stated that while attempting to turn off the vehicle, the vehicle failed to turn off. The contact shifted from park (p) to drive(d) and was eventually able to turn off the vehicle. The contact stated that the letter p(park) was outlined in yellow and was illuminated on the instrument panel. Additionally, the contact stated that while attempting to close and lock the driver's side door, the door failed to lock securely. The contact stated that the failures occurred simultaneously. The contact stated that the failures were intermittent. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 74,000.

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "p. " however, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (auto revival in justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

In March of 2022 the vehicle displayed a warning to service the side detection system. On March 31st 2022 the dealership diagnosed that the side blind zone alert module failed due to water intrusion. The replacement of the modular was completed free of charge under "campaign - n172097060 special coverage adjustment". In December of 2024 the same warning to service the side detection system was activated again, several weeks later the warning lights on the side view mirrors lite up and remained on. Upon bringing the vehicle on February 13th 2025 for service, in it was determined to be caused by the same failed part as the first occurrence. This time the repair was not covered by the dealer, and was 1099. 22. GMC has not solved the underlining problem with these parts. The side detection system is critical when driving a larger SUV for blind zone awareness to avoid collisions while driving in multi lane traffic. When the system failed, the lights on the side view mirrors made driving difficult due to the distraction and glare. Although this problem is known by the manufacture it has provided a permanent solution, as they continue to use the flawed original parts. Due to the sensor being electrical, there was no symptoms prior to failure; the warning appears and continued at each start up. The cost of repairing safety features on an ageing vehicle becomes a burden, especially when those features can only be repaired by a dealership at high prices. This keeps many people from maintaining or fixing their cars, putting others at risk. I have the modular from the most recent repair, and will include a photo if possible.

The known ‘shift to park’ GMC vehicle defect could cause vehicle to rollaway and possibly hit someone.

I randomly get a "shift to park" warning even though the vehicle is in park. It looks like there has been this same issue with older years but not my vehicle according to the VIN.

Shift to park error message when vehicle is in park and engine will not shut off. Not recognizing microswitch in the console. Needs a recall.

The car is put in park but the it doesn’t detect that it’s in park and won’t turn off. You can’t get out of your car because the won’t turn off. There were no errors before this. I get an error message that says shift to park. I have to shift the car into drive and then park several times to make the car turn register that it’s in park the dealership has not looked at my car. Nothing has ever been wrong with my car. I have read online that it’s a problem for many people with arcadia vehicles .

I was driving and making a left turn at a traffic light when all of a sudden, every light lit up on my dashboard. Then the dashboard turned completely black along with the radio screen. When the dashboard went black, I tried to stop by hitting the brakes to pull over. The brake pedal went all the way to the floor, and I had zero brakes. I was able to coast to a dirt shoulder where the vehicle stopped due to friction and gravity. The brakes never worked to aid in stopping the motion of my vehicle. I had my vehicle towed immediately to the dealership where I bought it.

While driving vehicle stalled multiple times in the middle of the road, with service transmission and engine light coming on, causing unsafe conditions, causing accident and leaving passengers stranded. Battery being drained and needing to be replaced multiple times within 2 years. Vehicle stopping and shutting off on the highway causing dangerous driving conditions!! radio and lights flickering, with radio freezing and shutting off. Electrical system not working properly and overheating!.

On 11/26/24 my wife was running errands in her vehicle when the power shut off and killed the car. She was in the left lane of a busy state highway. She was able to coast off the road slightly before the vehicle came to a complete stop. The dashboard said to press brake and start button, but the car would not start. The vehicle was also stuck in drive and would not switch to park, neutral, or any other gears. Police came and had to push her vehicle with theirs into a nearby park lot so a tow truck could pick it up. It is currently at a gm dealership waiting to be looked at.

While driving down the interstate at 70mph+, the instrument panel went black and restarted multiple times. The car continued to stay at a sustained speed, but I was unable to control anything or see how fast I was going. It appears as if the car has shut off, but it isn't. It also affects the lights. It has happened multiple times with no known cause. When I brought this up at the dealership, they said that it would be an $80 diagnostic fee and unless they can replicate the problem they can't do anything about it because it doesn't throw any error codes. There was another women in the dealership the same time as me with the exact same issue. No fix offered. Looking online and talking to others this seems like a common issue that GMC is ignoring.

This 2024 GMC Acadia will not back up safely on a rainy day. When moving backward, when it raining the emergency braking continually engage, approximately every two feet. I took it to gm dealer service center, it did the same with them. However, they can't correct the problem and gm does not have a fix. Also others vehicle like this one are experiencing the same problem. This has been an ongoing problem since July 5, 2024 in rainy weather. I called gm customer service and have gotten no result. I don't know what to do. Can you all help us (please). Thank you all so very much.

The contact owns a 2023 GMC Acadia. The contact stated that on several occasions while driving at various speeds, the vehicle began jerking with the "service stabili-trak" message displayed. The vehicle was taken to a dealer but was not diagnosed; however, the dealer tightened the battery terminal. The contact stated that the failure persisted. The manufacturer was notified of the failure. The failure mileage was 31,000.

The electrical, engine, and a/c systems failed. First our a/c stopped blowing cold. A warning light came up and said that driver assist was not working properly, and temperature gauge went all the way down to cold and did not move after that. It appears 3 things were malfunctioning. I was afraid to drive it for fear of burning up the engine due to an engine cooling malfunction and the car overheating. The a/c stopped blowing cold air but was still blowing warm air. The steering system alert was on the dash but wasn't an issue. I called onstar to diagnose the problem and they initially said they didn't see a problem but based on what I described it would be best to have it towed. I later got an email that an issue was detected, code p0128. I called my dealership and they also said to have it towed so they could check it. We were not in a position to have the car towed and for it to sit in the service department for 5 days (that was what their queue backup was like then). I took the car to a nearby shop to have it checked. Because I was afraid to drive it we I got it there by disconnecting the battery. A/c was blowing cold like arctic air and the temperature gauge went back to normal. We got it to the shop (a few miles away) and they could not duplicate the issue due to the battery disconnection "fix". They said the car would be temporarily functioning per usual but the problem will come back again soon and to bring it back when it happens. It happened 2 weeks later (2 hours from home/stuck in traffic). We found an auto parts store and bought a wrench to disconnect the battery again to get home and all was good once we did that "fix" again. We have a service appointment to have it repaired. Two quotes I got were for $1600 and $2200. Temperature sensors/thermostats were suspected to be the cause of the issue. The auto shop stated they frequently see this issue (p0128) with GMC vehicles in recent years, even when they are only a few years old. Ours is 4 years.

The "shift to park" error warning comes on even though the vehicle is in park. The vehicle will not turn off. I had this issue with my 2017 GMC Acadia. They tried to fix it once, but it came back. I see in the 2019 version that they have added an audible dinging to the warning. I would have thought after at least 2 years they would have resolved this issue. They just made it more annoying by adding the dinging.

Vehicle stalled on major interstate while giving no warning vehicle would not start after failure had to be towed to dealership found to be a faulty fuel pump module service advisor even said this is a common problem vehicle mileage was at 33,478 this could have been a deadly accident.

I would park my car and try to turn off car. The car would not turn off. The car continued to ding the car remained on. The safety issue is the car wouldn't turn off. After many many times shifting from park to drive it would finally park, this happened every time using the car. I discovered the same exact issue is a recall on 2017 & 2018 GMC Acadia our exact car ! called the dealer explaining shift to park issue. Brought the car to Buick GMC of mahwah they noted in fact it was shift to park issue. Two days later came in for the car they would not cover problem. Cost $950. 00 for exact recall the 2 years prior. Also, contacted GMC corp. They were no help just said had no recall. Our car is 2019 Acadia with 27,236 miles.

I am filing a complaint about my 2024 GMC Acadia at4, leased brand new from frank's GMC in August 2024, now with a little over 8,000 miles. The brake pads are worn to 35% life, far below the expected 30,000-70,000 miles, with loud squealing, fluid leakage, and odors. This poses a severe safety risk to my family and others, as compromised brakes could fail. In October 2024, before my 3,000-mile oil change, I reported brake concerns to frank’s GMC service manager, javier, who advised waiting. After the November 2024 oil change and tire rotation, only three months after obtaining my vehicle, javier claimed no issues, despite my prior warnings. The problems worsened, with squealing, leakage, and odors persisting. My March 19, 2025, service appointment was delayed, calls ignored, and follow-ups never occurred. Sales manager khaled stated that owner frank confronted javier about avoiding service issues, yet no action was taken. I contacted ten GMC service departments in PA, CT, and MD; they reported similar at4 brake issues, some citing total brake failure. I spoke with gm corporate supervisors, who referred me back to the dealer. Frank’s GMC inspections overlooked my concerns. A local police department safety inspection unit confirmed the issues, but no manufacturer or insurance inspections occurred. The vehicle is available for inspection. I urge NHTSA to investigate this premature brake failure and ensure the 2024 Acadia at4’s safety. The email screenshot I included was sent in April. I contacted the same GMC dealerships that previously reported no issues to check for updates, and they confirmed a change. All of them now report the same problem with brake pads and/or brake failure. This issue is covered under warranty and should be replaced without issue, but dealers are not complying. If overlooked, this could become a national concern.
