2017 GMC Acadia

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.

The contact owns a 2017 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle shuddered abnormally. No warning light was illuminated. The contact stated that the transmission and torque converter were previously replaced twice; however, the failure persisted. The vehicle was not diagnosed or repaired by an independent mechanic. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 138,000.

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
