What 374 owners told NHTSA about the 2019 GMC Acadia Denali

Problem 1: I got the car 2 years ago, and it keeps telling me to "Shift to Park" even though its in park. That's been happening for the whole time I've had it. It does throw a code for it on the scanner machine. I have to shift it back and forth sometimes 3 times and sometimes 17 times. It just keeps beeping over and over and won't shut off. I am having a mechanic look at it Tuesday but hoping it doesn't cost a lot. But no recalls on my car. Problem 2: For the last 4 months or so it keeps saying steering assist is reduced drive with car. It's being looked at Tuesday as well. I have 109K on my car, and got it at 86K.

When I shift my 2019 GMC Acadia into park, the warning message reads shift to park and there is a ding warning that plays for several mins. This has been going on for over a year. I took it to the dealership and they said they could repair it for 1000 dollars but the solenoid was only guaranteed for 30 days. There is no possible way a dealership can expect a person to pay 1000 dollars a month to keep their family and transportation safe.

Park to shift issue - the vehicle did not register that I was in park, jerked hard when trying to place in gear, did not register the PROPER gear (reverse, neutral, drive), would NOT unlock doors to let passengers out even if it were an emergency. Seems to be triggered on inclines but have also been having issues on flat ground. Other Acadia's apparently have a recall for this issue but my VIN does not register as recalled which is not acceptable. https://www.quillarrowlaw.com/blog/gmc-acadia-shift-to-park-recall-what-owners-need-to-know/ THEN trying to accelerate on road it acted as though in neutral, would only barely function in low gear. Again, gear shifting did not respond. The fab did not register to unlock the car (it has a new battery) or the trunk, or start the car just prior to the issue revealing itself.

The "shift to park" continues to pop up and can take as long as 20 minutes to get it to go off. From what I have seen this is a super common issues for the 2019 models and why there isn't an active recall I am not sure. Getting pretty frustrating when I have read 100s of complaints about the same thing and GM isn't doing anything about it.

My 2019 Acadia often will not turn off because it has a Shift to Park issue. Apparently it is caused by a faulty microswitch in the shifter assembly that fails to signal the Body Control Module when in park, leading to a persistent warning message, inability to turn off the vehicle and battery drain. It has been going on for at least 4 years. It appears there is a recall for this problem but when I search my VIN number a recall does not come up. There are many posts that say "certain" models in years 2017-2019 but why not mine? It is definitely a safety issue because it does not turn off.

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.

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.

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).

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).
