2019 GMC ACADIA Service Brakes Problems

The vehicle will be in park, and a message will pop up saying "shift to Park check and advise". Took my car into the dealer shop to get this fixed their response was the cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the park position.

Whenever parking the car and trying to stop (shut off) the engine it will randomly say “shift to park” and I cannot shut the vehicle off.

My 2019 GMC Acadia is now undergoing the same repair for at least the second time. This is the common issue known as the Shift-To-Park issue. You can read about it here - [XXX] Below are the commonly affected years: 2017 – Acadia 2018 – Acadia 2019 – several models (I own a 2019 GMC Acadia) 2020 – several models 2021 – Acadia and Traverse Despite falling into the year, make, model and issue - When I look up my VIN - No recall or warranty information is available, saying that my vehicle is NOT affected by this issue. However, this is now the 2nd (maybe 3rd) time I am having to come out of pocket to have this issue repaired. It originally happened in July of 2022 with around 40-44k miles on the vehicle. It is now happening again May of 2025 with around 72k miles on the vehicle. If I search further back, I imagine the first owner may have had the same work done too. Clearly this vehicle is affected by the issue buy according to my VIN it is not. GM (General Motors) told me that they offer no sort of help or reimbursement unless my VIN is associated with the issue. Can you guys please either add my VIN or extend out the warranty / recalls to ALL - Because this is absurd. My car doesn't recognize that it is in Park and stays on, preventing me from shutting down the vehicle / engine. Asking me to "Shift-To-Park" INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "P." However, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at Walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (Auto Revival in Justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

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.

Traveling at interstate speeds the vehicle had an short in the Body Control Module due to the HVAC drain leaking into the vehicle. The vehicle displayed a series of alarms brake, steering, and shutoff. We had no power, steering, brakes, or lights. The issue was discovered by Dave Sinclair dealership. It had been in for a sensor issue 3 months prior.

I have the shift to park error where my car is not recognizing that it is in park and will not shut off. I have been held hostage inside my car, late for work, etc because my car will not shut off because it is not registering that it’s in park. Also, my breaks are unbareably loud with whatever switch they made to the “new” brake material.

My car would not shift into park. The indicator in the center console would say that it was in park, but when I would shut it car off I would get a warning on the dash that said that I needed to shit to park. I started chocking the tires when I parked out of fear of the car rolling away or run over somebody. My wife would not always chock the tires. I took the car to the dealer today and they confirmed my issue. The dealer replaced a part on the transmission. The dealer has my old part. It cost me over $400.00 to repair. The dealer and manufacturer are aware of similar circumstances with this model. I started having issues two months ago without warning and the problem got steadily got worse. The car has 43300 miles on it. I have owned it since new. It has never been in any accidents.
