2019 GMC Acadia

For the past 4 months after turning off the engine, my vehicle is failing to recognize that it is in Park. I am getting a message on my display stating “Shift to Park”. This is preventing my vehicle from shutting down.

I purchased vehicle used 2 years ago last year. I noticed the air conditioner was not cooling. I summed it up too, and extremely hot summer.This summer I did the same thing.I took it in immediately. Catastrophic, I think I bought it like this. It fell apart, the air conditioning compressor fell apart.There is like shrapnel through everything, and they have to go through and clean everything out.It's gonna cost me over two grand. But it only be in 40000 miles on it. I understand it's a twenty nineteen, but owner said at forty thousand miles.This should never happen.

Shortly after purchasing my 2019 GMC Acadia with approximately 52,000 miles, the vehicle displayed a "Steering Assist is Reduced. Drive with Care." warning message and illuminated the check engine light with diagnostic code P0128 00 (Engine Coolant Temperature Below Thermostat Regulating Temperature). I disconnected and reconnected the battery, after which both the warning message and check engine light disappeared. However, the engine coolant temperature gauge then began behaving erratically. On multiple cold starts, the gauge would immediately indicate that the engine was already at normal operating temperature even though the engine had been sitting long enough to be completely cold. This led to a diagnosis of a thermostat and/or engine coolant temperature sensor failure. After researching the issue, I found many other owners reporting the same thermostat and engine coolant temperature sensor failures. I believe this is a widespread defect that should be investigated because incorrect coolant temperature readings can prevent the driver from knowing the true engine temperature and may result in improper engine temperature regulation, overheating, and possible engine damage.

Shortly after purchasing my 2019 GMC Acadia with 52,000 miles on it, my wife parked the vehicle in our driveway and shifted the transmission into Park. When she pressed the push button to shut the vehicle off, the instrument cluster displayed a "Shift to Park" message even though the shifter was already in the Park position. Because the vehicle did not recognize that it was in Park, it would not shut off completely. The radio remained on, and the doors could not be locked. The only way to get the vehicle to shut off was to repeatedly shift from Drive to Park until it finally recognized Park. This occurred multiple times. After researching the problem, I discovered that many other GM owners have experienced the same "Shift to Park" failure. I believe this is a widespread defect that should be investigated because it can prevent a vehicle from shutting off properly, leave electrical accessories powered on, drain the battery, and prevent the vehicle from being secured when parked.

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.

I am getting the 'SHIFT TO PARK' error message when I put the vehicle in park. When I looked up the error this is what I got... but I don't see a recall for my vehicle. The "Shift to Park" message in GMC Acadias (2017–2019, primarily) is a common, known issue caused by a faulty microswitch in the shifter assembly that fails to recognize when the car is in Park. This defect prevents the engine from shutting off, drains the battery, and requires a replacement of the shifter switch or assembly.

This vehicle has an electrical deficiency when trying to park, The console will NOT recognize that the vehicle is in park, causing bell warnings, beeping, and an INABILITY to lock the vehicle, thus draining the battery. We cannot walk away from it, nor ever leave anything of value in it. This is a recurring problem, causing stress, and having to start, shut off, re-start, wiggling the shifter knob, MANY times and HOPE that the electrical system will recognize that the vehicle IS in Park. sometimes this can take 20 minutes, IF it works at all. If not, We have to leave someone IN the vehicle when this happens, in order to do anything! This is a KNOWN problem with this shifter, and there SHOULD be a recall on it!

My 2019 GMC Acadia suffered a "major trans fluid leak" specifically from the transmission accumulator feed pipe. Because of this leak, the transmission lost its necessary hydraulic pressure, leading to "internal damage". This is why I experienced harsh shifts and a complete "missing 3rd gear". This exact part and failure mode are the center of NHTSA Recall 20V668. The recall warns that missing bolts on the accumulator can cause a fluid leak, progressing to a total loss of propulsion—which is exactly what has happened to my vehicle.

2109 Acadia. The gear shift would not register as being in park when it actually was in park. This created an issue of the interior lights and radio not being turned off when the driver door was opened, posing the possibility of the battery being drained and the driver stranded. Upon searching, it was learned many Acadias have had this issue, including a friends'. This was reported to GMC Executive Resolution Team and that it cost us $341.38 to get it repaired. They refused reimbursement and have not issued a recall even though many Acadias are involved in this problem.

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.

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.

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.

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

Shift to park error on dashboard When turning the car off and it is in park, the car does not register that it is in park and continues to run electronics in the car. Causing the car to show the error on the dashboard. This runs the battery down and car may jump out of park and roll. Asked dealer to look at it and they refused due to it not being on the recall list for my vin #. No, dealer refused and no other person will touch this issue, since its electronic in the vehicle and only the dealer can fix. Had it to another repair shop that informed me of this information. No known abnormalities prior to the incident that occurs every time you try to shut off the vehicle. Causing several attempts to turn the car off and make sure it is off and does not move on its own.

Owner of a 2019 GMC Acadia Denali (VIN: [XXX] , current odometer ~87,164 miles), purchased new. In early February 2026, the check engine light came on. Independent diagnostic scan confirmed persistent P0420 code (“Catalyst System Efficiency Below Threshold Bank 1”) as current, history, pending, and permanent. Inspection showed the front exhaust pipe bracket had snapped, damaging the flex pipe and causing an exhaust leak. This failure mode directly triggers the P0420 code and requires replacement of the bracket and affected flex pipe section. This is a known recurring issue on GM’s Lambda-platform vehicles (shared platform, 3.6L V6 engine, and exhaust system design). GM Special Coverage Adjustment N212356540 covers 2019 Chevrolet Traverse and Buick Enclave models for front exhaust pipe bracket separation (resulting in pipe damage, holes, leaks, rattling, or efficiency codes), providing free repair for 15 years or 150,000 miles from in-service date, regardless of ownership. The failure on this Acadia is mechanically identical, yet the model is excluded from coverage despite matching part design and numerous similar owner complaints documented on NHTSA and BBB reports. Multiple attempts were made to resolve through the selling dealership (no response to service inquiries). Matter was escalated to GM Executive Resolution. GM required a redundant diagnostic scan at an authorized dealer (additional cost incurred), despite independent confirmation of the issue. GM ultimately denied any coverage, TSB applicability, goodwill assistance, or further support. The snapped bracket and resulting exhaust leak can produce noise, fumes in cabin, potential component damage, and emissions noncompliance via false/legitimate catalyst efficiency codes. Inconsistent application of coverage for the identical defect across equivalent Lambda-platform models raises concerns about a widespread safety/emissions issue affecting 2019 GMC Acadia.

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.
