ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER
Odometer Fraud. The contact purchased a 2016 GMC Acadia on February 28, 2026. After purchasing the vehicle, the contact obtained a Carfax report and discovered that there was a mileage discrepancy. The vehicle was a dealer sale. The contact called the dealer and was informed that the vehicle was purchased at an auction. The dealer agreed to refund a portion of the cost of the vehicle. The contact attempted several times to contact the dealer afterwards but was unsuccessful. At the time of purchase, the mileage was 92,400, and at the time of registration, it was discovered that the mileage was 192,000.

UNKNOWN OR OTHER, LANE DEPARTURE: ASSIST
The shift to park keeps showing up and I had this issue taken care of last year at the dealership and it just started again. It is over $600 to have the repair done and should last more than a year before it needs to be replaced again. The lane assist pops up every couple weeks that it is not working.

EXTERIOR LIGHTING, ENGINE, ELECTRICAL SYSTEM
This is ongoing from the purchase of the car. 1) Infotainment computer screen daytime illumination is so dark as to be a major safety issue as it causes too much time looking away from the road to operate the system. If you wear sunglasses you cannot see the screen at all. The dealer says nothing can be done to improve the problem. 2) Right rear tail light stopped working after 500 miles. Replacement requires dropping the rear bumper and quarter panel. The dealer actually damaged the body of the car while replacing the light. Where are the days of changing out a light bulb? 3) At 1200 miles the transmission torque converter is chattering and slipping on cruise control at 50 MPH. 4) Engine noise is very loud during acceleration. Seats seem flat with no bolsters and little cushioning.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
In November 2022, I started getting a dashboard "shift to park" on my 2019 Acadia after I had parked and shut the vehicle off. At the time I took it into service to have it looked at/repaired, they told me there would probably be a recall on this issue,as it seemed to be a frequent problem, and I would get a refund for the repair. That recall never happened, and now my car is once again displaying the same issue. The dealership will not cover the repair, and I will be responsible, as it is out of their 2 year warranty window. I can't just ignore this issue and keep driving, as with the "shift to park" display, there is a constant alarm that doesn't stop unless the park switch recognizes the car is in park, even when it is shut off. I feel this issue needs to be placed under a recall, and I should not have to pay AGAIN for it to be repaired.

POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
The vehicle experiences a transmission/drivetrain defect involving delayed gear engagement, hesitation, and apparent slipping. When accelerating from a complete stop (especially onto an incline) the engine RPM increases but the vehicle fails to accelerate as expected. The vehicle jerks and shakes violently and is unable to gain speed. This issue is intermittent but highly repeatable and occurs almost every time when there is a slope immediately after a stop sign. It results in loss of acceleration, violent shaking, and inability to maintain or build speed, creating a serious safety risk in traffic. It first happened around 1 year (early 2026) after the new car purchase (Nov 2025). There are no warning lights or messages. The dealer claimed they were unable to reproduce the issue during a brief test drive without me present and incorrectly attributed it to a bulletin without performing a detailed diagnosis or repair or looking at the video we recorded on the issue. The issue persists and affects safe operation of the vehicle. No inspection has been done by police or insurance. In one instance, this occurred while other vehicles were approaching from behind, creating a dangerous situation where I could not accelerate to match traffic flow. This resulted in a high risk of being rear-ended due to the unexpected loss of acceleration. I am aware of other consumer reports describing similar transmission-related symptoms such as slipping, hard shifting, and hesitation in this model. Some complaints describe transmission issues occurring at low mileage without warning lights.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Automatic brake engaged unnecessarily/ unexpectedly while driving forward at a low speed. There was no reason for the brake to engage. There were no objects or people infont of us. This has happened twice in less than a month. Both times we were in a forward motion. It could have been a serious situation if the car behind us had been any closer when we suddenly breaked for no reason.

ENGINE AND ENGINE COOLING
The contact owns a 2021 GMC Acadia. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. In addition, the coolant fan was running after the engine was turned off. The vehicle was taken to Auto Zone to be diagnosed due to the check engine warning light being illuminated. The contact was informed that DTC: P1098; was retrieved, which indicated a fault with the coolant control valve. The vehicle was taken to the dealer, where it was confirmed that the coolant control valve had failed. The vehicle remained at the dealer unrepaired. The contact related the failure to the Manufacturer Recall Number: N252508341. However, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised that the VIN was not under recall. The failure mileage was approximately 69,000.

ELECTRICAL SYSTEM, ENGINE
My Acadia keeps an error message of "Shift to Park" this has been happening on and off for about 8 months. Now it goes on every time I try to shut my car off. I have to stop and start it up to 20 times before it shuts off. I am concerned that I may be somewhere and won't be able to turn it off. I know there have been recalls for this and I need this repaired. It's obviously a flaw on GMC and honestly, I should not have to pay for it. At this point, the car is only used close by my home. I don't feel safe using it. Please help. Not only me but all drivers affected. Thank you

POWER TRAIN, STRUCTURE:BODY, ENGINE
We purchased our 2024 Acadia in June 2025. Since we have had the vehicle, it has been in the shop going on 6 times. First the sunroof seal came off, then the antenna cover fell off, the driver side rear panel had to be replaced because it was coming off. Once all this was done then the vehicle started leaking transmission fluid, took it to the dealer to get fixed, once we get it back the coolant starts leaking from the radiator hose, took it in to get repaired, now there is knocking noise coming from the engine/hood. Every time we take it in to get repaired a new problem pops up. We purchased the vehicle to have a safe way to get our kids around and it has been nothing but a headache and run around from the dealership. GMC really needs to resolve this issue. Parts seem to be on never-ending backorder with no ETA.

ELECTRICAL SYSTEM
Shift to Park warning comes on when the car is turned off and it is in park. When we park the the car and shift the car to park and turn the car off the warning "shift to park" comes on and the electrical systems will not disengage. The radio stays on, the car can not be locked, and the doors ding loud alarms if you try to exit the car. The only fix is to sit in the car for several minutes and flick the switch under the gear shift and hope that the shift to park warning eventually goes off and you can exit the car. It sometimes takes 8-10 minutes for this to happen. This first happened intermittently and now happens every time we turn off the car. It has been replicated in a dealership and service center. The independent service center that did our brakes said they were aware this was a common problem in GMCs and they experienced it. We have been told it is a microswitch and the repair option is not under any kind of recall or warranty and up to us to pay for the full repair even though it seems there are thousands of people online experiencing the same problem and paying hundreds of dollars for this fix.
