My car would not shift into park. The indicator in the center console would say that it was in park, but when I would shut it car off I would get a warning on the dash that said that I needed to sh*t to park. I started chocking the tires when I parked out of fear of the car rolling away or run over somebody. My wife would not always chock the tires. I took the car to the dealer today and they confirmed my issue. The dealer replaced a part on the transmission. The dealer has my old part. It cost me over $400 to repair. The dealer and manufacturer are aware of similar circumstances with this model. I started having issues two months ago without warning and the problem got steadily got worse. The car has 43300 miles on it. I have owned it since new. It has never been in any accidents.

2019 GMC Acadia started producing error code of -??shift to park-?? around 32,000 miles. This malfunction is directly connected to a know a non manufacturer flaw in the shifting mechanism shifter switch an faulty grounding. The error code -??shift to park-?? will not allow you to properly shut off or start the car causing potential safety threats to individuals involved. This error code is a know issue with the shifting mechanism GMC has been putting in Acadia models for the last 5 plus years with no proper resolution to correct potential hazard for consumers. Recall Bulletins are in place for some 2009-2017 models currently, but only a temporary fix. Consumers are expected to pay for repairs for a manufacturer defective part that doesn-??t meet nhtsa requirements. I would like to add the 2019 models to this list. Vehicle was inspected by GMC dealership and master mechanic.

About five months ago, my GMC Acadia started displaying a warning when I would put the car in park, and try to turn it off. The engine would shut off, but the electrical portion of the car would stay on, and would not turn off, because the warning displaying said "SHIFT TO PARK". I have tried every conceivable way to try to get this to go off, but nothing works. My car has stay on for upwards of two and a half hours, to the point where my battery died in the car and left me stranded. There have been numerous accounts of this, as I had read them on forums, yet still no resolution has been published. I have tried taking it to be inspected, but nothing ever comes up. I have two very small children, and if I were to be in public and be stranded because my car wouldn't turn off.... I would be livid.. Also, because of this warning, it prevents the doors from being locked. That is another major concern for me, considering the day in age we're in.

The vehicle intermittently fails to recognize that it has been put into park, flashing a message on the dash instructing the driver to -??shift to park-?? even when the gear lever have already been moved to the -??P-?? position. I find it amazing that GMC even has a Service Bulletin No.: 19-NA-206 to address the situation (Intermittent Shift to Park Message Displayed While Vehicle in Park) but yet I had to pay $561.47 for the repair to ensure I don't injure my passengers and/or others.

With the vehicle shifter in park and the dash indicating in is in park I get an error message stating to "Shift into Park." This has happened serval times in the last few weeks intermittently. I am very concerned this will strand my wife and child or lead to the vehicle unintentionally rolling away while unattended. While talking to several technicians at a GM test facility I have been told this was/is a common issue. While searching the NHTSA complaints multiple multiple complaints for this issue have bee submitted.

- Troy, MI, USA

Vehicle has had a hard shift since 15000 miles, always told at dealership it was normal. At 87493 my check engine light came on and code P2097-00- I was told it was that I had a bad battery and GM would not provide me one. Light was reset. Now at 98000 miles, shifting harder (automatic) like a jolt and vibrates going up hill- told I needed transmission fluid changed, this did nothing. This was confirmed by dealership prior to fluid change and then the dealership would not set up another appointment. Had this confirmed also by an independent service center. Occasionally a light will come on to say shift into park, despite being in park. No other messages related to this.

Occasionally my vehicle will say "Shift to Park" when I turn off the vehicle, but the vehicle is clearly in Park. It has been happening more frequently lately. I have researched this problem and it appears it has been a problem with several other GMC Acadia's as well.

When I got to work this morning, I put my 2019 Acadia in park and tried to turn off the car. An alert popped up that said, "shift to park, " but the car was already in park. I turned the car off and then back on and it corrected, but this is the second time in two days this has happened.
