2019 GMC Acadia

Vehicle continued to have Shift to park message when car was already in park. This is a known issue in some other GMC vehicles. Safety issue that the battery could drain or the car could roll unexpectedly. This message repeatedly displayed on the vehicle. The dealer confirmed the problem and performed the repair. Repair order number is XXX for $549.17 on XXX at Boucher Buick GMC of Waukesha [XXX].While there isn't a recall on file for this specific VIN number, I believe it should be included in the recall and I am requesting reimbursement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

shifter micro-switch is not working and is available for inspection upon request. Vehicle is not shutting off as it is indicating shift to park. The vehicle unable to shut off can cause issues while parked in the garage still running and worried about causing a fire. Problem diagnosed by private individual but have plans on taking it to dealership. The shift to park indicator issue has been occurring for almost a year and has progressively gotten worse. I have noticed other vehicles with the same make/model/year have had similar issues with known defects that a recall was issued.

I am submitting this complaint to request that NHTSA investigate a potential safety defect involving the engine coolant temperature monitoring system, thermostat/engine coolant temperature sensor system, and its relationship to reduced steering assist in 2019 GMC Acadia vehicles. My 2019 GMC Acadia, currently at approximately 61,500 miles, has experienced the following symptoms: • The engine temperature gauge remains flat or reads abnormally low/cold. • The cooling fans run continuously at extremely high speed, creating a loud "screaming" fan noise. • The vehicle displays the warning message "Steering Assist is Reduced — Drive with Care." • The vehicle has a history of diagnostic trouble code P0128, "Engine Coolant Temperature Below Thermostat Regulating Temperature." I am concerned that these symptoms are related and represent a potential safety defect rather than an isolated thermostat or cooling-system repair. GM has issued bulletin PIT5967, "Service Steering Message With P0128," which applies to GMC Acadia vehicles from model years 2017 through 2023. The bulletin states that when P0128 is present, the ECM may be reading coolant temperature incorrectly and that a "Service Steering Message" may be displayed to protect the steering gear in the event of an undetected overheating condition. GM instructs technicians to diagnose and repair P0128 first. GM bulletin 17-NA-158 also describes a relationship between P0128, an invalid coolant-temperature signal, and the "Steering Assist Reduced, Drive With Care" warning. The bulletin explains that the steering module relies on valid coolant-temperature information to provide additional steering assistance under cold conditions. When the coolant-temperature signal becomes invalid, this function can become inoperative, potentially resulting in a heavier-than-normal steering feel.

WHEN I PUT THE CAR IN PARK, I GET AN ERROR MESSAGE THAT SAYS SHIFT TO PARK AND IT TAKES PUTTING IN PARK NUMEROUS TIMES TO GET IT TO CLEAR SO I CAN TRUN THE CAR OFF AND LOCK IT. I KNOW THERE HAVE BEEN SOME MODELS THAT HAVE BEEN RECALLED DUE TO THIS PROBLEM, HOWEVER MINE IS NOT INCLUDED IN THAT RECALL. I WOULD LIKE TO KNOW WHY IT IS NOT INCLUDED AND IF THERE IS ANY HELP AVAILABLE TO CORRECT THIS ISSUE.

I purchased vehicle used 2 years ago last year. I noticed the air conditioner was not cooling. I summed it up too, and extremely hot summer.This summer I did the same thing.I took it in immediately. Catastrophic, I think I bought it like this. It fell apart, the air conditioning compressor fell apart.There is like shrapnel through everything, and they have to go through and clean everything out.It's gonna cost me over two grand. But it only be in 40000 miles on it. I understand it's a twenty nineteen, but owner said at forty thousand miles.This should never happen.

Shortly after purchasing my 2019 GMC Acadia with 52,000 miles on it, my wife parked the vehicle in our driveway and shifted the transmission into Park. When she pressed the push button to shut the vehicle off, the instrument cluster displayed a "Shift to Park" message even though the shifter was already in the Park position. Because the vehicle did not recognize that it was in Park, it would not shut off completely. The radio remained on, and the doors could not be locked. The only way to get the vehicle to shut off was to repeatedly shift from Drive to Park until it finally recognized Park. This occurred multiple times. After researching the problem, I discovered that many other GM owners have experienced the same "Shift to Park" failure. I believe this is a widespread defect that should be investigated because it can prevent a vehicle from shutting off properly, leave electrical accessories powered on, drain the battery, and prevent the vehicle from being secured when parked.

I am getting the 'SHIFT TO PARK' error message when I put the vehicle in park. When I looked up the error this is what I got... but I don't see a recall for my vehicle. The "Shift to Park" message in GMC Acadias (2017–2019, primarily) is a common, known issue caused by a faulty microswitch in the shifter assembly that fails to recognize when the car is in Park. This defect prevents the engine from shutting off, drains the battery, and requires a replacement of the shifter switch or assembly.
