My Shift To Park senor come on often and wouldn't let me turn the vehicle off. I have taken to dealership for repair. Long wait and because parts are back ordered due to numerous vehicles having this same problem. This has left me stranded in my vehicle and not able to turn it off and leave the vehicle. I feel this is unsafe and should be handled on a recall. I am now without a vehicle for who knows how long?

Something inside the wheel started smoking and my gmc app displayed low break fluid. I pulled over and had someone come out two days later. The breakpad had uneven wear and the caliper had a broken seal on it which in turn tore the caliper up! This was not a safe situation to have with 4 kids in the car. This car has been one problem after another !

The contact stated that the failure occurred intermittently but became frequent. A dealer and the manufacturer were notified of the failure and informed the contact that there were no recalls on the vehicle, and a diagnostic estimate was provided. The vehicle was not repaired. The failure mileage was approximately 30,000.

The contact owns a 2017 GMC Acadia. The contact stated that while the vehicle was parked on an incline with the engine turned off, the contact's toddler was able to shift into drive(D), and the vehicle rolled backwards, hit a light pole and a basketball stand, causing damage to the front driver-side door. No police report was filed, and no injuries were reported. The contact was unable to shift back into park(P) and was forced to start the vehicle in neutral(N). The contact was then unable to shut off the vehicle as the gear shifter was no longer in park(P). Upon investigation, the contact learned that it was necessary to manually flip a switch underneath the gear console for the vehicle to register that it was in park(P). The contact initially took the vehicle to the independent mechanic but was referred to the manufacturer for assistance. The manufacturer was notified of the failure, and the contact submitted a claim with pictures and videos of the failure. The contact was then instructed to take the vehicle to a dealer for an inspection. The contact was later informed by the claim manager that the claim would be denied, and no further assistance was offered. The vehicle was not repaired. The failure mileage was 99,968.

Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.

Imagine wrapping up your errands and stepping into your GMC Acadia to drive home. You arrive and everything seems fine until you park, press the button to shut it off, and a “Shift to Park” message lights up the dashboard. Thinking you might have made a silly mistake, you double-check the shifter, only to realize it’s already in Park. It has become so rampant, has drained my battery and caused anxiety.

UNKNOWN I’m told the micro parking switch is the problem. This is an intermediate issue. This is a well known problem with the GMC Acadias. Their times when I try to turn off the engine, I get a shift to park error message. The car will not turn off, I’m unable to lock the doors and I’m concerned that the car is not in the park position thus and fearful, it can roll away. This has been occurring more often than before.

I keep getting this warning "Action Required Steering Assist Is Reduced Drive With Care" . This warning has occurred randomly for several years. Recently, after getting this warning the check engine light came on and the engine temp gauge stopped indicating. I have seen a bulletin from GM that this condition is covered under a 'special warranty extension' for a single model year, but it is common over at least 5 model years. This should be a recall because of the steering assist issue.

Driver's side seat belt lower attachment point. Has a flexible cable swage attachment to the lower seat belt and. This braided steel cable has failed at the swage. No accident involved. Just a fatigue failure over time. But since this is a safety system, I thought I should report it. It seems very similar to the earlier seat belt failures on the same GMC platform. That recall is included as a reference document

Twice the side detection system failed due to corroded wiring under the bumper which then led into the electrical system failing on side air bag detection/blind zone detection/traction control system/display monitor and blinkers all failing to the point of vehicle not starting. The safety is these features failed which were both safety and stability. Risks occur in becoming stranded and the problem was first noted by dealer to be a poor battery. GM pushed out a "Special Coverage Adjustment' to have the wiring/module kit to be ordered and repaired by a dealer for no charge. Stipulations was within 6 yrs or 80,000 from 'placed in use'. Warning lamps occurred after the corrosion was too far along to be rectified and after the 6n yrs off the lot. Manufacture GM issued the special adjustment but dealership did not provide notice beyond letter at point of failure in vehicle so that twice I have had to contend with this issue and pay in full for the service work performed. The second fail of this wiring system and module was within 3 years of first replacement.

Seeing the intermittent shift to park messages when the vehicle has been shifted into park and the ignition is turned to the off position. Shifter wire harness jumper & transmission controls A malfunctioning shifter raises fears of potential rollaway accidents, even if such cases remain rare. For anyone who has to park on a slope, this fear can cause serious worry. Yes, there is a service bulletin (19-NA-206) No, this is 1 of the only problems I have had with this. The other issues I have had is the clear coating on the rims are peeling
