2019 GMC ACADIA Power Train Problems

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.

The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 85,695.

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...

The transmission is shuttering and jerking, had it diagnosed and was told that the torque converter is going out with only 137,000 miles on my 2019 GMC Acadia

There is a "shift to park" alert that is listed as a recall from 2017-2019 gmc Acadia's. I have this alarm but apparently my vin is not affected. I would like this to be investigated as it seems my vehicle should be included in the recall.

Thermostat fails. Steering assist reduced message comes up on dash. Temperature gauge stops working, air conditioning stops working and engine fans run constantly when vehicle is running. I had the dealership fix and replace under warranty the first time and now it happened again a second time.

Shift to Park message comes up and vehicle will not turn off. This happens frequently and so far I have been able to get it to shift into park by clicking the lever on the shifter multiple times.

The vehicle will be in park, and a message will pop up saying "shift to Park check and advise".

When trying to park car, vehicle will not detect the shifter is in park. If the car does not detect its in park it will not turn off and stays running hampering your exit from the vehicle. This is truly an unsafe condition due to not knowing how to get the car to shut down as well as not knowing if the car will roll if you do get out.

I noticed when I put my car in park and turn key off, it’ll ding to warn me to “shift into park” this been becoming a problem recently and it’s been happening more often.

About a month ago when I shifted my vehicle into park and shut the vehicle off, "Shift to Park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "Shift to Park" appearing. On 7/11/25, Arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off.

This could take up to several minutes and many tries. If I had of left the car all the warning would have been sounding indicating it wasn't in park. I...

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in Ohio, but ours was manufactured in Tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the...

Shift to park light comes on and car won't shut off

Shift to park issue. This 2019 Acadia Denali has been serviced twice for a shift to park issue:(It’s a known problem that occurs when Acadia vehicles fail to recognize that the gear shifter is in the park position). The first time was under warranty in 2022 and it has just been serviced again for the same problem. The system is the same as the older GM recall for this problem and the recall should also include this model as well but unfortunately it does not.

Car has delayed shifting, and jolting when switching gears. Transmission temp gets up to 270 degree while driving

Component: Shifter Assembly & jumper harness Safety concern: Can't turn off vehicle - Carbon Monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running... Message in dash was present when I brought vehicle to dealer. Dealer also replicated No inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. GM is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair.. I was charged $778.98 for the repair, and GM's customer assistance...

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to...

Our Arcadia 2019 with 40000 miles has shift to park problem. 2017 thru some 2019 had recall notice and were fixed by GMC. Why doesn't it apply to this vehicle. We had to pay $1500 to dealer. There is an obvious problem and they have admitted it. Time for government to step in or do a class action lawsuit looks like they are filed by state

When shifting into Park the car still states to "shift into park" on the dash and will not fully shut off. i still need to take the car into the dealer for service to fix. This seems to be an issue.

Shift to park message when vehicle is in park not allowing vehicle to be shut off

Our car has the well know shift to park issue but shiws no recall. Is it possible GM might fix this defect?

I’ve taken my car to the dealership twice for transmission issues. One time the engine/transmission light came on, they kept it for a month and told me they didn’t find anything. Wrong. 2 months later I took it back because it felt like it wouldn’t change out of gears and felt lint the transmission was slipping, they told me they me since it wasn’t a light on they couldn’t check it without a code. I then had to take it to another dealership because a code came back on and they said it was something. Four months later my transmission went out while I was driving down the hwy. I have a 2019 gmc Acadia. I had the same similar codes on 3 different occasions.

I am constantly getting a “shift to park” warning after putting my car in park. My car sometimes will not shut off because of this. It’s a safety issue for me because the car is not registering that it’s in park and my battery could very well die while I’m out with my children. This is a common complaint from what I’ve researched and needs to be fixed by GMC.

The check engine light came on 12/2023. The vehicle was taken to Pep Boys and AutoZone in MD, WalMart and O'Rilley in Bastrop, LA, O'Rilley in Midlothian, TX. They could not find any problems with the vehicle. I took the vehicle to GMC in Plano, TX. THey charged me for a new battery but the check engine light remained on after I picked up the vehicle with a newly installed battery. The dealership said it would eventually go off. I took the car to Automotive Solutions in September 2024 and they can not find anything wrong with the vehicle. The car can not pass Texas inspection with a check engine light on. There is a large group on FB having this same problem. August 2024 the car will recognize when it is shifted into park. Sometimes it rolls after puting the car in park.I took the car to Automotive Soulutions...
