2019 GMC Acadia Power Train

My 2019 GMC Acadia has shift to park warning light that repeatedly keeps coming on I've tried to park it have to turn it off two to three times maybe four times I have paperwork that I have went to the dealer and they have fixed it twice with a harness that is failing it only is a temporary band-aid fix. Even though in Indiana we do not have a recall as I know of for this year I would need to have this fixed for my safety I fear that one time it may not go into park and I may not be able to shut my car off.

The contact owns a 2019 GMC Acadia. The contact stated that while attempting to park the vehicle, the gear shifter failed to shift into park(P). The vehicle failed to turn off, with the message "Shift to Park" displayed with an audible chime. The contact was forced to move the gear shifter back and forth before it was recognized that the transmission was in park(P). A dealer was notified of the failure and the contact was provided an estimate for the repair. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 69,000.

Started getting a warning indication when starting the vehicle that stated some portion of driver assist was not functioning (or some verbiage close to that). We didn't notice any difference in the operation of the vehicle and took it to a service shop after about a week. They did some testing and discovered the problem. I am not mechanical at all but they said there were several technical bulletins from the manufacturer that led them to the problem - a bent pin on one of the rocker arms. I am going to upload the technical bulletins (3) they provided me as well as the invoice (3 pages).

The contact owns a 2019 GMC Acadia. The contact stated that the vehicle failed to shift to park(P) as intended and could not be turned off. The message "Shift to Park" was displayed. The contact was able to turn off the vehicle after shifting to low gear. The local dealer was contacted and confirmed that the VIN was not included in a recall. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 60,000.

When I placed the vehicle in park, the dashboard alert/warning would signal "shift to park". This would continue to go off for quite some time, and it continued to get worse and take longer to shut off. Eventually the alarm would not go off I turned the car back on and off, nor if I engaged with the shifter. I could not leave my vehicle in this state, and I was unable to determine if my vehicle was truly in park, which is a huge safety concern to myself and others. This also caused the battery to drain, and could impair being able to start and run the vehicle. This problem has occured on many GMC vehicles, and there have been recalls issued for the other cars. I would like a recall issued for my VIN as well. I spent $800 fixing this issue and GMC will not cover the cost, even though this is a known problem with other Acadia's (even 2019).

In March 2025 my 2019 Arcadia with only 44112 miles begin indicating a Shift to Park error message when I parked and shifted into park the error message showed on the instrument panel and the warning alarm sounded and would not stop showing the error message until I restarted the car and shifted from drive to park repeatedly. I couldn’t get out and close the door, and the warning stop, it would continue to sound the warning. The only way to stop the warning message and alarm was to stay in the car and repeatedly start the car shift to drive into park switch it off and if it still showed the error and warning, do it all over again. This could take up to several minutes and many tries. If I had of left the car all the warning would have been sounding indicating it wasn't in park. I didn't know if it was really in park or not and if not, the car could have potentially rolled off causing injury or damage. To try and determine what was the cause of this problem I searched the internet to find a solution, to do a reset or simple fix and discovered that GMC had known about this issue since 2016 and the only solution was an in the shop repair requiring replacement of some parts. The "Shift to Park" error in GMC vehicles is considered a safety issue by many owners and has led to class-action lawsuits. The issue, which prevents vehicles from recognizing when they are in park, can lead to the engine not shutting off, potential for vehicle roll away, and even entrapment inside the vehicle. On April 16, 2025 I had the repair done at Hayward Allen, Cadillac – GMC dealership, 2590 Atlanta Highway, Athens Georgia 30604. The total repair cost was $732.36 (invoice attached). ). I sent a copy of this invoice by email to GMC customer service. After customer service reviewed the amount they call and informed me they could only reimburse me a total of $73.24.

Shift to Park message comes up and vehicle will not turn off. This happens frequently and so far I have been able to get it to shift into park by clicking the lever on the shifter multiple times.

Thermostat fails. Steering assist reduced message comes up on dash. Temperature gauge stops working, air conditioning stops working and engine fans run constantly when vehicle is running. I had the dealership fix and replace under warranty the first time and now it happened again a second time.

When trying to park car, vehicle will not detect the shifter is in park. If the car does not detect its in park it will not turn off and stays running hampering your exit from the vehicle. This is truly an unsafe condition due to not knowing how to get the car to shut down as well as not knowing if the car will roll if you do get out.

When shifting into Park the car still states to "shift into park" on the dash and will not fully shut off. i still need to take the car into the dealer for service to fix. This seems to be an issue.

For 3 weeks now, my dash keeps telling me to shift to park when my gear shift is already in park. Car will not allow me to secure it because it thinks the car is not in park!

I have a 2019 GMCAcadia Denali with less than 60000 miles. The problem I have with the vehicle is I get a error that say "Park to Shift. I don' know if it is in park or not. I am afraid that it isn't in park and will create a safety issue and injuries. It is my understanding that the same problem with the 2020+ GMC Acadia and is listed in a RECALL. Why isn't 2019 not included in this recall?
