2017 GMC Acadia

The "shift to park" warning light comes up every time I put my car in park. I have to move it back and forth multiple times to get it to acknowledge that its in park or the vehicle will not shut off. This is a dangerous situation in that the car could easily roll when I am not in it. I know that this is an ongoing issue with the 2017-2018 GMC Acadia and don't understand why GMC won't issue a recall for this. If this were to cause injury or an accident then they are 100% liable. I started having these issues about a week ago. My husband took it to the dealership and they told him that its not a recall or under warranty. I cannot afford to fix this myself at this point.

The contact owns a 2017 GMC Acadia. The contact stated that the gear shifter acknowledged while shifting to park and activated the Press-to-Start button to turn off the vehicle. The message to shift to park was displayed on the instrument panel while the gear shifter was already in park. The dealer was contacted and confirmed there was no recall on the VIN. The vehicle had not been taken to the dealer. The vehicle had not been diagnosed or repaired. The manufacturer was informed of the failure. The manufacturer confirmed that the VIN was not included in a recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 36,000.

The transmission in the car failed. These failures are a known problem with this vehicle and while attempting to get assistance from GM, they refused to offer any assistance, compensation or otherwise. I understand the transmissions in these models are part of a larger inquiry. I would like to be compensated for having to have the transmission completely rebuilt after less than 7 years of ownership. GM has known and willingly decided not to repair these. While outside of warranty, this is clearly a design and manufacturing flaw.

While parking, cannot turn off the vehicle because of a warning to shift the transmission to park, even though the shifting mechanism is in the park position. Happens very frequently where sometimes up to 10 minutes trying over and over to safely park the car. Has been happening for all of 2024 but getting increasingly more difficult to park.

The contact owns a 2017 GMC Acadia. The contact stated while driving at an undisclosed speed, the transmission unexpectedly downshifted, with the shift to park message was displayed. The contact attempted to restart the vehicle, but the vehicle failed to shut off when the contact attempted to engage the parking brake. The contact forcefully engaged the parking brake to shut off the vehicle. The vehicle was taken to the dealer where it was determined that the transmission failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 13,000.

Many times after shifting the car into park, a message is displayed saying that the car needs to be put in park. It takes many time of turning the car on and off and moving the shift back and forth in order to get the message off and get the car to shut off. I notice that some 2017 and 2018 Acadia models have received recall notices addressing this problem. Our VIN number does not show up in the recall notices. Is there a reason why our car would not be covered as we have the same issue as cars that have received recall notices. Any help that you could provide would be very much appreciated. It is a very frustrating problem.
