SHIFT TO PARK WARNING. VEHICLE WILL NOT POWER DOWN.

FUEL/PROPULSION SYSTEM

The shift to park in my 2018 GMC Acadia was faulty. On many occasions and randomly, the car would be in park but would not turn off, saying I needed to shift it to park in order to turn the car off. This has left me unable to turn my car off resulting in dead batteries and missed appointments and being late for work. This defect is well documented by GM in TSBs PIT5616A, 18-NA-297, and 19-NA-206, which describes the exact symptoms and repair that I had to have completed. This problem has been on going and as a teacher I cannot continue to be late for school because my car, though in park, would not turn off. Given GM’s prior acknowledgement of this defect, I believe reimbursement is warranted. I have never been notified of a recall on this.

BACK OVER PREVENTION: WARNINGS

My 2018 GMC Acadia is having the shift to park error. Causing it to not park; or error it causing us not to be able to turn vehicle off or know if it's in park. It pops up multiple times.

SUSPENSION

Rear right hand lower suspension control arm broke in half, after further inspection it looks to have been separated from its original factory form which then cause uneven load on the arm causing it to fracture in half. The factory form separation seems to have been ongoing for unknown time due to surface rust is visible at the factory mold separation, where it snapped in half there is no surface rust. Fortunately it happened when I was only moving the vehicle to make space for another, the broken arm cause the wheel to turn to the right as if it was making a right hand turn and I can't imagine if it would have happened while driving in the city of even worse on the freeways... It would be a certain crash and safety for us and those driving around us. Last photo is from Amazon listing, I did order the part from another source that is a factory GM part and I am doing the repairs of replacing this myself as I am mechanically inclined. Thanks

When I put my vehicle in park, the message “shift to park” pops up. It has been doing this for well over a year. I have already had to replace a battery once due to this because I didn’t realize it was still on. It does not happen everytime I park but at random times. The more it happens, the longer it takes for it to go off. At this point, I can only hope my car is really in park. I jiggle the shifter, hit the “ +|- “ on the shifter and have to turn the vehicle off and on about five or six times. Eventually it will go off. It took me 20 minutes today for it to go off in 100 degree heat. The vehicle’s AC is not running when trying to get the shifter to go off. It keeps the electronics running but not the AC. I keep waiting to receive a recall on this vehicle because of this issue but still nothing. I have noticed there is a recall for this but not vehicle. I have already replaced one battery due to this issue and do not want to continue to replace batteries and worry if the vehicle is really in park or not.

My 2018 GMC Acadia has had the "Shift T Park" alarm and indicator going off after my car is turned off and in "PARK" It only happens intermittently, but frequently enough to be annoying. The dealer and GM told me because my VIN wasn't in their recall range, they would not honor the recall. This has been happening since I purchased the car in 2018.

There is a current recall on the 2018 GMC Acadia for a "Shift to Park" issue. It clearly states that GMC is aware of this issue and my vehicle is having this issue but for whatever reason, I am being told we are not part of the recall. My VIN is not coming up with it either but we are having the same issue.

ELECTRICAL SYSTEM

Component/System: Transmission selector / electrical system (“Shift to Park” defect) Yes, vehicle is available for inspection upon request. I own a 2018 GMC Acadia. Since I purchased the vehicle used in June 2019, the car has frequently displayed a “Shift to Park” message even when the vehicle is in park and the gear shifter is fully engaged. This message prevents the car from turning off completely, leaving electrical systems running, the ignition on, and draining the battery. This issue has persisted nearly daily for the past five years. I brought the vehicle to a GM dealership in September 2020, while it was still under factory warranty, but the problem was not diagnosed or repaired at the time. The dealership could not reproduce the issue, but it continued regularly afterward. I am now paying nearly $900 out of pocket to have it repaired. Safety Risks: The vehicle does not fully shut down, increasing risk of electrical malfunction or battery failure. I am often unsure whether the car is truly “off,” which could pose a fire hazard or lead to the car rolling unexpectedly if the system misreads the gear position. This defect has also caused me to get stuck in unsafe areas, repeatedly turning the car off and on, jiggling the shifter until the system registers park. The constant battery drain has left me stranded with a dead vehicle multiple times. Reproduction / Confirmation: The issue has been reproduced by an independent repair shop and will be fixed at my expense next week. A GM dealership inspected it in 2020 but failed to diagnose or confirm the issue at that time. Inspection: The vehicle has been inspected by a GM-authorized service center. Not inspected by police or insurance representatives. Warning Messages or Symptoms: The “Shift to Park” message appears on the dashboard even after the vehicle is correctly shifted into park. This began shortly after purchasing the vehicle in June 2019, worsened over time, & still has the inability to turn off properly.

The contact owns a 2018 GMC Acadia C1. The contact stated that his wife was parking in the driveway and upon shifting into the park gear, the vehicle sensor would not register that it was in park, therefore not allowing the engine to be shut off. The contact stated that his wife proceeded to turn the vehicle on and off while continuously shifting the gears until finally placing the shifter into park, and successfully turning the vehicle's engine off. The contact noted that his wife exited the vehicle; however that moments after a loud bang could be heard, and upon inspection, the contact noticed that the vehicle rolled into the garage with the entire front bumper. No property damage was reported. The vehicle came to a stop upon impact. The vehicle was going 3 MPH at the time of the crash. The vehicle did not need to be towed. No warning lights were illuminated however, the "Shift to Park" message will display on the instrument panel. A police report was not filed. The vehicle was not destroyed. The local dealer was contacted however, the vehicle was not diagnosed as the contact was advised that the vehicles VIN was not included in any open recalls. The vehicle was not repaired.

When putting my GMC Acadia in Park and shutting off the push start ignition the alarm goes off saying it’s not in park when it is clearly in park so I have to continuously start the car and try to keep putting it in park and shut ignition off. I googled it and saw there was a recall so took it to dealership but my vin was not included. I feel my safety is at risk as my battery also went dead stranding me in another city with my young grandkids on February 23rd, and I had a large bill to get a jump as well, I believe due to this same electrical issue! We are waiting on estimate now to get it fixed which is ridiculous as it is the same issue that is covered on many other of the same model vehicles! You should really look into this and maybe other electrical safety concerns costing consumers thousands of dollars on all these GMC vehicles it doesn’t seem fair. Thank you.

For the past two weeks, when the Acadia is put into park and the engine is turned off, the warning bell chimes nonstop and a dashboard message appears to put the vehicle into park even though it is already in park. The vehicle needs to be restarted and then put into drive or reverse and then back into park. With irregularity it may or may not work. Sometimes the car must be turned on and off 5 or 6 times before it recognizes that the transmission is truly in park.

All of this has been going on for a while but it's gotten to the point of dangerous. The Shift to Park keeps coming on preventing me from shutting the vehicle off even though it's, in fact, in Park. Then, "Steering Assist Reduced Drive With Care" keeps coming on. This will come on and off. Preventing the engine from heating up like it needs to be. Then the transmission keeps slipping. Was nearly rear-ended on the highway with my child in the car when it decided to start driving really rough and wouldn't allow me to shift to the next gear. This is also an ongoing issue. Another time I was almost hit in the side when this randomly happened on crossing the highway. This is absolutely absurd! I have had MUCH older vehicles without all these issues with many many more miles! I can't count the amount of times this has caused us serious hazards not to mention almost costing me my JOB! Interestingly enough, the same year/make/model has been recalled for the exact same issues yet for whatever reason GMC says MY model "was not affected by the recall". Funny how it's having the EXACT same issues as the ones on the recall list! GMC needs to fix this before they cause people to die! I'm a healthcare worker and this is disgusting!

It's a problem that occurs when my Acadia fails to recognize that the gear shifter is in the park position. As a result, the car doesn't fully shut down, leaving the engine running. Unable to shut down vehicle if shift doesn't fully activate brake notice, and could be a safety issue if it truly doesn't park. I have not taken the vehicle to a dealer or services to have the problem reproduced yet. It also has not been inspected yet, however, after doing research online, GMC did put a recall notifying owners that this may be a problem in vehicles from years 2017-2021. When I place the shifter into park, the car does not recognize it, and alerts me to put it into parking. It started appearing 2 months ago.

My car will not recognize when it is in park. The shifter will say park but the panel says on and all accessories are staying on. It started out doing it every once in a while but now it does it nearly every day. At work I have had to just leave it like that in the parking lot to keep from being late for work and the accessories stay on. Once I had to call for a jump start after work because my battery was dead. I’m not sure if it can be stolen or not when I have to leave it like that but I don’t think it could possibly be safe. And I can’t afford to call for jump starts all the time. Thank you and please help.

My vehicle has a persistent shift to park issue. My vehicle cannot be safely turned off. My vehicle needs to be restarted multiple times and the gearshift moved to the park position for the chance that it will register being in the parked position so the vehicle can be safely turned off.

ENGINE

A warning popped up on my dashboard stating "Power steering reduced. Drive with care." multiple times. Whenever the warning popped up, my air conditioning would stop working and my engine fan would run very loud. The warning would go off and back on over the course of a year. This started in the beginning of summer, 2024. On 4/3/25 I took it into an auto mechanic shop and after they looked at this warning, they confirmed that the thermostat has an issue where it gets stuck in the "open" position, therefore the thermostat isn't working properly and my car thinks it's over heating, when it's really not. If my car were to overheat while this thermostat wasn't working properly, my engine could overheat or worse. The thermostat part is being replaced today so after today, it won't be available for inspection upon request.
