general problems of the 2019 GMC Acadia - part 2

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.

I would park my car and try to turn off car. The car would not turn off. The car continued to ding the car remained on. The safety issue is the car wouldn't turn off. After many many times shifting from park to drive it would finally park, this happened every time using the car. I discovered the same exact issue is a recall on 2017 & 2018 GMC Acadia our exact car ! called the dealer explaining shift to park issue. Brought the car to Buick GMC of mahwah they noted in fact it was shift to park issue. Two days later came in for the car they would not cover problem. Cost $950. 00 for exact recall the 2 years prior. Also, contacted GMC corp. They were no help just said had no recall. Our car is 2019 Acadia with 27,236 miles.

Last week I parked in a large public parking lot and attempted to turn my car off. I received a notification in my dash to “shift to park” even though my car was already in park. I was unable to turn the car off or lock the doors. I ended up having to leave. I have now gotten this message six times in the past week. It can take up to twenty minutes to get the car to turn off so I can exit. Yesterday upon returning to the car I showed an error message as soon as I started it that the parking brake needed service, stabilitrak is disabled and steering assist is disabled- drive with care. As I tried to exit the parking lot, I found it almost impossible to turn the steering week. I pulled over and restarted the car, releasing the steering wheel so I could get home. This morning, all of the service lights were on and periodic warnings flashed on my dash throughout my drive to work. I contacted the dealership and was told that there is a recall for this exact issue on the 2015-2018 models of my car. I have a 2019. This is certainly a dangerous issue that should be proactively fixed and is clearly still present in years that are not being included in the recall. I was told my car was one month past its warranty and told I could pay 250$ for the issue to be assessed and then they could quote me on a fix. The dealership acknowledged that this is an issue they regularly fix.

My car will not shut off as I am parked and “shift to park” is alerting me. The car keeps beeping. I have to re-start it multiple times and shift it in and out of park for it to finally go off. This last time it took 25 min to shut my car off.

When attempting to park vehicle, the alert "shift to park" populates and the car will not completely shut down. This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off. If it's not in the proper park position, the car can continue running, battery drainage and possible roll out of place. This also causes issues with the transmission not shutting off. I have not had this particular vehicle inspected, but contact with dealer service departments confirms continued complaints of this issue and it has not been addressed by GMC/general motors. Problem has been occurring at various times over last 3 years.

My radio is going crazy. Like going through every radio station, calls people. Its a distraction. And after researching how to fix I noticed thousands of people have the same problem. Almost cause an accident because of the distraction and this is obvious problem in GMC.

My car is saying it’s not in park when it is in park.

When I put my car in park and try to turn it off, the dash shows an error message "shift to park". The car will either not turn off the ignition or allow me to leave the vehicle or lock/unlock the doors. It alarms incessently--even when trying to move the shifter around. Takes several times of restarting and shifting to get it to clear so I can put it into park and exit the vehicle. Local dealer is charging me over $2000 to repair the transmission control shifter assembly; bcm low signal; in-line shifter wire harness jumper--exactly one month after my warranty expired. It's a known Acadia (and other gm vehicle) issue--per several bulletins--na-19-206 as an example.

Shift to park will not work. Sometime after 20 try’s it may work once but I have to disconnect the battery to turn off the car. I’m beside myself and cannot keep doing this. This is a real safety problem. I have children in my car and gm says there is no recall and I am expected to pay 800. 00 and then it is not guaranteed.

After raining door locks on every door will not work. Won't lock or unlock, manually or by using the key fob. Something seems to be getting damp and shorting out . After a day or 2 the locks will work just fine when everything dries out. Seems to be a safety issue if I can't exit the vehicle. The rear hatch is the only door that works when this happens. What is the problem and the solution? this happens every time it rains. Had it to the dealer and they couldn't find the problem.

My vehicle just hit 39k miles, it has all of a sudden started giving me a shift into park warning. The sensor is not registering that its in park and will not let you turn car off.

After noticing my ac was not cooling, I began receiving a “steering assist is reduced drive with care” notice every time my car was started. My car is more difficult to steer. It has been assessed by a certified mechanic and found that the coolant temperature probe is malfunctioning and the ecm will either need to be fixed or replaced. Due to malfunctioning power steering, I do not feel safe driving this vehicle until it is fixed.

The touch display screen. It has started to constantly go through every setting on the car while driving. I’ve tried turning the screen off. It works for a few minutes and then turns itself back on. It will change radio stations. It will make phone calls if a phone is detected. It is a constant distraction while driving GMC is obviously aware of the problem. You can call a service center. They will tell you that it happens all the time and that the part will cost you around 800$ not including service charges. With how many people depend on display screens in today’s technological ways. It’s only a matter of time before a serious accident occurs from this, if not already that hasn’t been reported. Also this affects more than just my vehicle. It’s across most of GMC models. Several public forums related to this issue.

My 2019 GMC Acadia started having the known "shift to park" issue that is affecting these make/models. This is a known issue and GMC has not issued a recall for it, nor are they covering any cost of repair. When the car is put into park, the screen displays a message that says "shift to park". This results in being unable to turn the car off. The vehicle will not lock either when the message is displayed. On several occasions, the car would not start because of this issue. We took it to the dealer and they are fixing the issue for just over $500 usd.

There have been no reported recalls yet my vehicle is on it's third battery since purchasing it? how is this possible?.

For a few months I intermittently get an engine light on, the temperature gauge goes to zero, the ac stops working, and an error that driver assist in unavailable. This will happen for a fee days and return to notmal where everything is fine. This happens on and off again. I google searched this and it is a huge problem with GMC Acadias. I used an obdii scanner and get a p0128 coolant error when this happens even though the temperature is fine. I just recently went over the new car warranty and GMC will not tell me if this is covered or not.

The vehicle’s steering assist reduced, drive with care notification came on. The vehicle lost steering assist control and made it very difficult to steer. The slightest move causes a major shift in the intended direction. This is very dangerous.

When I put my car in park and try to turn my vehicle off I get an error message saying “shift to park. ” the problem is the car is already in park and I am unable to turn the off. I usually have to start the car back and drive back and forth before the car actually recognizes it is in park. Im concerned for my safety.

The vehicle would continuously not register as being in park.

Initial battery died completely when vehicle was 2 years old (17 months ago). This week got a steering assist drive with care message and everything pointed to codes signaling low voltage. Battery tested with a bad cell. Gm will not cover the cost to replace a battery when not one but two have gone bad well before the middle of their earful lives. Gm claims there is nothing electrical drawing from the battery causing both the go array. Bad customer service on gm’s part. Logically this issue should be covered as it is not a typical maintenance replacement. It’s something causing two batteries to go bad!.

Gear shift notification problem. Unable to turn engine off after receiving "shift to park" message and the gear shift is visibly in the "park" position. In addition, the doors would not lock. My wife was forced to stay in the unlocked running car in a store parking lot for 25 minutes, until the car just "turned off" on its own. Unsafe for a woman (or anyone) to have to do at 10:30pm. This puts drivers in a really vulnerable position. Vehicle taken to dealer Jan 30, 2023. Was told they were familiar with the problem.

Vehicles shift lever doesn't always go into "park" and when the 'stop' switch is pushed the instrument panel displays notice to "shift to park" even though the operator has already done so. The audio still plays after the vehicle door is opened. So I assume the vehicle is still using battery power.

Vehicle refuses to turn off due to "shift to park" error being displayed. Vehicle also gives "driver assist unabled. Drive safely" message and ac will not cool and vehicle coolant gauges will not work.

While driving the all the the service lights came on on the dashboard and the system as well as the stabilitrak notification. The car begin to not want accelerate and I had to put on the hazard lights on a drive very slow home. Upon arrival home the car would not start but would not power off either and the a "shift to park" warning message is displayed.
