2019 GMC ACADIA Complaints

The warning steering assist reduced, drive with caution appears. Shift to park appears. Temperature gauge drops to zero. Fan runs on high. A/C & heater don’t not work when this happens. We certainly do not feel safe driving our Acadia like this. Can’t trust that it won’t start on fire.

When shiftiing to park and turning the car off the message "Action Required Shift to Park". It is difficult to get the message to go away.

My 2019 GMC SLT seems to be having sensor problems. I keep getting a message that my driver assist is reduced and my A/C only blows out hot air. It’s done this to me randomly id say about 4-5 times. It will go off as I’m driving and than my temp gauge goes to zero. I did research and alot of other users have the same issue and say thermostat or thermostat sensor. If I disconnect my negative on battery and wait a few minutes it will work again.

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.

2019 GMC Acadia message: Action Required Steering Assist Is Reduced Drive with care Both power steering and AC affected, check engine light on, engine temperature gauge off

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.

It has the ABS lights on and tire traction light on check engine light on and given signs of failed transmission Slow to takeoff shuttering of transmission

I see where GMC Acadia is have a recall on transmission and if it’s the description of my two GMC Acadia’s, but when I put my Vin number in it doesn’t have a recall

In November 2022, I started getting a dashboard "shift to park" on my 2019 Acadia after I had parked and shut the vehicle off. At the time I took it into service to have it looked at/repaired, they told me there would probably be a recall on this issue,as it seemed to be a frequent problem, and I would get a refund for the repair. That recall never happened, and now my car is once again displaying the same issue. The dealership will not cover the repair, and I will be responsible, as it is out of their 2 year warranty window. I can't just ignore this issue and keep driving, as with the "shift to park" display, there is a constant alarm that doesn't stop unless the park switch recognizes the car is in park, even when it is shut off. I feel this issue needs to be placed under a recall, and I should not have to pay AGAIN for it to be repaired.

My Acadia keeps an error message of "Shift to Park" this has been happening on and off for about 8 months. Now it goes on every time I try to shut my car off. I have to stop and start it up to 20 times before it shuts off. I am concerned that I may be somewhere and won't be able to turn it off. I know there have been recalls for this and I need this repaired. It's obviously a flaw on GMC and honestly, I should not have to pay for it. At this point, the car is only used close by my home. I don't feel safe using it. Please help. Not only me but all drivers affected. Thank you
