   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 manufacturer was notified of the failure, and the contact submitted a claim with pictures and videos of the failure.

13. Filed Jun 18, 2026Failure Jun 15, 2026Wichita, KSElectrical system, Fuel/propulsion system, Power train

    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.

20. Filed May 13, 2026Failure May 12, 2026Nine Mile Falls, WASteering

    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.
