Numerous occurences especially recently of shift vehicle to park when vehicle has been parked, turned off and already shifted into park position. Several occurrences where almost every time within 24 hours I use my cruise control and air conditioner at the same time my check engine light will come on as well as the stability trac indicator which then causes my air conditioner not to work and inability to start the vehicle due to having a check engine light on.

We own a 2018 GMC Acadia Denali. Upon shifting the vehicle into park, we cannot turn off the engine. The vehicle gives us a "Shift to Park" message on the instrument panel. As a result, we are unable to shut off our engine and, to avoid the battery running out, are forced to attempt to move the shift lever in and out of "Park" to get the car to detect that the shift lever is in fact in -??Park.-??-??

I shift the car into park but the vehicle tells me the car is not in park and won't shut off. GM charged me $656 to replace the switch and harness.
- Hilliard, OH, USA
Erroneous error code on heads up that car not in park. Appears to be in park, error code can be reset by activation/deactivation of trigger switch on shift lever. Provides unclear message if car is or is not in park, vagueness makes me question vehicle park status overall. Issue was very intermittent in 2022, frequency of erroneous error code increasing now happens 1 out of 5 times when shifting to park.

2018 Acadia will display -??Shift to park-?? warning along with an audible warning when the vehicle is shut off. This happens even though the PRNDL display is in the -??Park-?? position each time. If I try to exit the vehicle, the audible warning continues (apparently indefinitely). This began at an odometer of about 59,200. Initially, the situation could be corrected by restarting the car and shifting in and out of Park or depressing the shift knob several times. Within a couple of hundred miles, it became consistent and eventually could not be corrected as described above. Unfortunately, this is not covered under warranty. I began driving for a few months without the shift knob, simply depressing the plunger on the shift rod coming up from the transmission. Doing this, the warning rarely occurs and, if it does, it-??s easily corrected with one or two presses of the plunger. Some modifications of the shift knob have allowed the knob to be used with results similar to driving without the knob. I hope there will be a software update (deployed over OnStar) to use the PRNDL information and eliminate this failed system.

Shift to park issue. Vehicle appears to be in park but message appears. You have to continuously wiggle shifter and shut car off and off until it registers it is in park. I have no way of knowing if vehicle is truly in park or not. For safety reasons I cannot park in an incline due to concerns the vehicle will roll backwards. Several TBS bulletins have been issued by GMC on this known issue and they deny any responsibility of fixing the situation with a recall. The NHTSA needs to step in and investigate and require GMC to remedy this dangerous defect

When I put the car in park, I get the message "Shift to Park". It does not do it every time but it is happening more and more. I have to wiggle the gearshift or restart the car and shift to neutral to try it again. I am wondering about the safety issue and will the vehicle roll if I am not able to get the message to go away? I have researched this and it is happening on a lot of vehicles.
- Valliant, OK, USA
The contact owns a 2018 GMC Acadia. The contact stated that on three separate occasions while driving at undisclosed speeds, the gears inadvertently shifted from second gear to third gear and then to neutral. No warning lights were illuminated. The vehicle was taken to the dealer on three separate occasions where the failure could not be duplicated. The vehicle was then taken back a fourth time where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.

In 2019 my GMC Acadia had the -??shift to park-?? issue in which my vehicle would not shut off and I would have to repeatedly start and shift the gear shift before it would shut off. The problem was -??fixed-?? at the dealership in June 2019. In May 2022, the -??shift to park-?? issue started again. At the dealership now and was informed that since the vehicle is out of warranty, I would be responsible for repairs this time. This is a safety issue that GMC is well aware and should not happen to begin with let alone after repairs. In no way am I going to be held responsible for repairs that obviously were done with either defective parts or parts that were limited to only 3 years without my knowledge. If I knew I would have to do the same repair in 3 years and I would be responsible for it, I would have argued for better parts to begin with. GMC needs to know that this is a real problem that needs to be dealt with immediately.

- Macomb, MI, USA
After putting the vehicle in park, I get a "shift to park" error. The car does not recognize it is in Park, so it will not shut off completely. It takes several attempts of restarting the car and putting back into park before it will recognize it is actually in "Park". This has been happening for several weeks.

Shift to park not happening. Stop the car and then the shift to part indicator shows up in the driver information center. So far I have been able to clear it out. Going into the dealer first thing in the morning. I have looked and there appears to be a class action on this issue and a TSB. I just bought this vehicle and was not told about this issue.

When I put my car in park and turn off it will randomly say "shift to park" it started doing this in Aug or Sept 2019 the car was under warranty and I brought it to a dealer to "fix". fast forward April 2021 it started to say shift to park again and car is no longer under warranty. Called different dealers even the one I brought the car to fix problem (that was a joke), they know its a problem and saying since that part got fixed in 2019 with a bad part and now there is a a newer fix that should work better, but I will have to pay for diagnostic test and part again. Again they know it is a problem with these cars and it needs to be recalled. I have to turn the car off and on reshift, push the shifter harder, etc to get the message to go away so I can turn my car off.
