Parts # 84733196 Harness ASM-TRAS CONT WRG and 84955379 SWITCH ASM-TRNS CONT have been replaced three times. This is described by dealer as a faulty PARK SWITCH. When this switch fails the vehicle is unable to be shifted to park. Vehicle needed to be located in a level position, wheels chocked and battery disconnected to safely disable the vehicle. Dealership and General Motors has been made aware of problem won't do anything, other that have me pay for the labor and new part to fix it, AGAIN. There is no warning ,it simple decides to fail to shift to park.

Vehicle experiences multiple simultaneous failures including “Steering Assist Reduced / Drive With Care” warning, extremely loud cooling fan operation, temperature gauge not functioning, tire pressure monitoring system failure, and widespread electrical issues (windows, mirrors, infotainment delay). Issues occurred together and are consistent with numerous owner reports for 2019 GMC Acadia models. Condition affects steering assist and engine temperature monitoring, creating a potential safety risk.

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.

Shift to park alert continues to come on when car is already shifted into park. Car will not shut off without pulling car back out of park and shifting back into park. Causing a delay in all electrical attached to power down, potentially draining the battery.

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).

My park to shift to park warning keeps coming on. It was replaced under warranty once and came on again comes and goes and dealership is not replace it again saying it isn’t tripping a code so it won’t get covered under the parts warranty.

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).

Shift to park caused by a faulty micro switch. Woukd take up to 30 min to get car in park, leading to engine shutdown failures and possibly battery drain I did replace battery before I knew this was causing this. Messages did appear saying this was an issue ,must shift to park but no indication of how to do it. I got this repaired at barkley GMC Dec 29:30

My Temp control sensor is causing my check engine light to come on. After reviewing the problem, It seems many owners have had this same problem nation wide. I,m simply adding to the complaints by other owners that this should be a recall problem since so many owners are having this same problem. I,ve only had this car for 2 weeks & like the vehicle very much but this is a per the mechanic that may be caused by the sensor being placed too close to the exhaust without better protection from the heat. Please take this into consideration & hopefully come up with an adequate protective cover

Won't shift into park alert came on. Vehicle wouldn't shift into park. Danger of vehicle roll off? Took to GM dealer who replaced GM part 13545094 transmission controller aka shifter assembly. It is believed this defect was detected and recalled on 2018 GMC Acadia models. My 2019 was made in 2018. In service date 10/04/18.

Shift to Park Issue - this is a know issue/recall for the 2019 GMC acadia yet it when I enter my VIN number the recall doesn't show up as a problem. YET it took me 10 tries yesterday to try and turn my car off because each time I went to turn it off, I got the message to Shift it to Park. This has been occurring weekly since I purchased the used car in August 2025.

There are 2 issues im experiencing. The first is the vehicle won't allow me to shut down the engine because it doesnt recognize that its been shifted into "park". Ive already paid close to 800.00 to.have this repaired because my model year is not covered in the recall. Today, it started doing it again. The safety issue is that either I, my wife, or my teenage daughter (depending on who is with the vehicle). Can be left stranded, unless we pop the hood and disconnect the battery. The second issue is that the tire pressure monitor is no longer working. It is sending warnings that our tire pressure is low. When its not. The safety issue is needing to pull to the side of the road to check the tire pressure and also not knowing when the vehicle may actually have a low tire.
