I purchased vehicle in 2018 and by 2019 it started showing a message that said error Shift need to park but I was parked and gear in parking mode .I reported to dealer but said they couldn't help me since my warranty was over due to my job I drive alot so I was over the mileage. So they itbwouldnt be covered since then it goes off and on same message and now I can't get off car until it goes off because I'm afraid to let go of brake if the parking gear don't work. I reported to dealer in time to get assistance but they just brushed it off blamed me for the mileage Maybe causing it but I see here I'm not the only one complaining about message "Shift".
When I park my 2018 GMC Acadia, my infotainment screen states the following warning: "SWIFT TO PARK", but I have already put my car in PARK. This warning started appearing around 28,000 miles; my currect mileage on my Acadia is 28,379 miles. I have checked if there are any recalls on this issue, but found none, but this issue started appearing in the 2017 models
Car won’t go into park though I’ve shifted to park. Car starts beeping and displays “SHIFT TO PARK!” even though the vehicle is shut off and gear shifter is in park position. I took to dealership, they stated, “gmc NEEDS to recall this, we have to repair every single GMC Acadia we sell with unfortunately the same defective parts” it’s a $500 fix. I just use my parking break everytime I park now.
The GMC Acadia displays a "shift to park" error. The truck is in park (or appears to be) and the truck says it is not and will not allow it to be turned off. This is a common error with the truck and GMC is refusing to take responsibility and this can cause a fatal error if the truck is not in park and rolls away.
The shift leaver when putting in park has an error code that the vehicle is not in park when it shows it is. The dealer said this is a common problem and replaced the shift leavers wire harness for 600.00. When this happens there is no way to turn the veh power off and it rolls a little before it engages.
I own a 2018 GMC Acadia and sometimes after shifting the vehicle into park and turning it off I get a message that says "shift into park" even though it is in park. This happens intermittently and but it is a bit of a pain when it does. I have to either jiggle the shifter or start the car up again and shift into park again. I just called the GMC dealer where I purchase the vehicle new, Mark Porter in Pomeroy, OH, and they said there is a bulletin from GMC on it and the fix is to replace the shifter harness which would cost me around $300. And they said if that doesn't fix the problem the next step would be to replace the shifter which would cost me another $500. In looking online it seems to be happening to a lot of 2018 GMC Acadia's and am wondering why there is no recall on it.
Shift to park error when turning off vehicle, which would not allow the engine to shut off. Had to have shifter and harness replaced.
In 2019 my GMC Acadia had the “shift to park” issue in which my vehicle would not shut off and I would have to repeatedly start and shift the gear shift before it would shut off. The problem was “fixed” at the dealership in June 2019. In May 2022, the “shift to park” issue started again. At the dealership now and was informed that since the vehicle is out of warranty, I would be responsible for repairs this time. This is a safety issue that GMC is well aware and should not happen to begin with let alone after repairs. In no way am I going to be held responsible for repairs that obviously were done with either defective parts or parts that were limited to only 3 years without my knowledge. If I knew I would have to do the same repair in 3 years and I would be responsible for it, I would have argued for better parts to begin with. GMC needs to know that this is a real problem that needs to be dealt with immediately.
“Action required Shift to Park” indicator comes on when trying to park vehicle. Vehicle does not recognize that it is in park. Vehicle will continue to move a short distance before recognizing that it has been placed in park and then comes to an abrupt stop. Vehicle sometimes has to be shifted between drive and park several times before it will recognize that it is in park.

Shift to park not happening. Stop the car and then the shift to part indicator shows up in the driver information center. So far I have been able to clear it out. Going into the dealer first thing in the morning. I have looked and there appears to be a class action on this issue and a TSB. I just bought this vehicle and was not told about this issue.
When I put my car in park and turn off it will randomly say "shift to park" it started doing this in aug or sept 2019 the car was under warranty and I brought it to a dealer to "fix". Fast forward april 2021 it started to say shift to park again and car is no longer under warranty. Called different dealers even the one I brought the car to fix problem (that was a joke), they know its a problem and saying since that part got fixed in 2019 with a bad part and now there is a a newer fix that should work better, but I will have to pay for diagnostic test and part again. Again they know it is a problem with these cars and it needs to be recalled. I have to turn the car off and on reshift, push the shifter harder, etc to get the message to go away so I can turn my car off.
Vehicle will not shut off as it shows shift to park. Reoccurring problem.

Also, when speed between 40mph to 50mph, the transmission exhibit severe hesitation to downshift when press throttle pedal. Moreover, the transmission exhibits harshness when downshift when decelerating from 45mph to 0mph.

Place shifter in "park", turn off engine, and get "shift to park" message on console. While message is displayed, the car constantly beeps, warns, lights not turning off. Have to start the engine back up, and place the shifter into drive and then back to park. Sometimes have to do this 5-10 times in order for the car to turn off. This first happened at 11k miles (under warranty) and dealership fixed. I am now at 16k miles and it is happening again (out of warranty this time).
Car would shutter on acceleration. Rpm gauge would jump when accelerating or downshift to pass/climb hill. Dealer found problem with torque converter. Metal through out transmission (see attachment for specifics as noted by mechanic)
Car displays 'shift to park' message after transmission gear selector has been placed in park. Car will not turn off and the tires roll freely. After numerous attempts of shifting in and out of park the car will finally recognize that it is in park and allow you to turn off the vehicle as well as lock the transmission.
Every time I put the car in park position the car doesn't sense that it's on park and error message keeps appearing in the screen saying 'shift to park' and the car refuses to turn off and it roll away from the drive way and I have to shift it back to drive and again to park again and again multiple times till the sensor feels it. It's a safety hazard. I looked up the issue online and found out that most of this car owners experience the same problem and there's multiple lawsuits against gmc for this issue. This car is driven by my wife most of the time and she has my kids with her in the car. It's a life threatening issue! I took the car last month to the dealership and they refused to fix it for free because the car went out of warranty by only 2k miles, and I couldn't take the car to the dealership when this issue started because of the covid. By the time we could visit the dealership we already drove over 5k miles and that puts the car outside the warranty limit.
