GMC Acadia Shift To Park Class Action Lawsuit Filed In Texas201
Back in December, we reported that many GMC Acadia owners had experienced a problem with the crossover in which the vehicle would not properly shift into park and would display a message reading “shift to park” on the dashboard. Owners chimed in to share stories of similar problems they had experienced, with our article attracting hundreds of comments from agitated GMC Acadia owners.
Now, a new class-action lawsuit has been filed over the GMC Acadia shift to park issue. According to Car Complaints, the class-action suit was filed by Lemberg Law on behalf of Plaintiff Brandy Smith, who purchased a new 2017 GMC Acadia and began experiencing the shift to park issue shortly after in April of 2017.
Most owners who report experiencing the problem say the vehicle will not recognize when the vehicle has been put in park, even when the gear selector has been moved from the ‘D’ position to the ‘P’ position. The class action suit says owners have to “resort to all sort of gimmicks to get their vehicles to detect that the shift lever is in fact in ‘Park'” when they experience the problem, including wiggling the gear level around in place and taking it in and out of ‘Park’.
This problem can leave GMC Acadia owners stranded. There is little the driver can do when the vehicle will not shift into ‘Park’, as the vehicle will simply roll away when they get out of it. The vehicle also does not shut off fully when it is not in ‘Park’ as a safety measure. The plaintiff in the new Texas class-action suit said she has been left “stranded inside her vehicle at home, at work, at school, and at various other places away from home, unable to shut her vehicle off,” on multiple occasions.
GM has already posted Technical Service Bulletins relating to the issue online, suggesting it is aware of the problem. According to Car Complaints, GM has said the cause of the problem is “unknown” and its engineering department “is still investigating the root cause.”
One TSB posted in October of 2018 and dug up by Car Complaints says “some customers may comment on an intermittent Shift to Park message when in Park and turning off the vehicle,” and “the cause of the condition may be the park switch in the transmission control (shifter) assembly not pulling BCM signal low to electronically show Park condition.”
GM dealerships have been told to replace transmission control shifter assemblies, but these repairs do not work in all instances, previous owner complaints indicate.

I see two things here some folks who are dealing with a bad dealer. Most dealers just fix it and move on. Also if under warranty and they keep it they give you a loaner.
The other is we have a few strangers here that never post. Being a legal case I can see them sending plants to post in their favor. It happens often in stories for class actions where law firms are chasing money not justice.
This is a simple documented fix. If out of warranty complain to Gzm and do not take no for an answer, they will either cave or cut you a break. Others have done this so you can.
The lawyers are not going to get you a thing unless it is a private case and even then the shifter is cheaper.
It’s sad that this is going on.GENERAL MOTORS STRESS SAFETY SO MUCH.I believe the owners should stay on GM.Its a safety issue and they should be accountable for it.You need to stick together on.Its sad that some dealers and Engineers are stupid of this issue.I really think they knew something about it.All the plants want to push vehicles out.Alot of this doesn’t get up to the upper management.
Our brand new 2018 Chevy Traverse was doing the same thing for quite awhile. I had it in the dealership twice before getting the entire shifter assembly replaced.
Problem is most likely a shift linkage adjustment underneath the car. Have the dealer repair man put the car on a hoist loosen the shift linkage rod to the transmission with the car in neutral the linkage should almost adjust itself or slide barely one way or the other into the proper position tighten a nut recheck the shift lever and almost guarantee of the problem will be fixed that easy. Had seen similar issue on Cadillac CTS that we owned I fixed it myself. Curious to know please respond
My 2019 left me stranded in the parking lot. The lights on the dashboard went black the car wouldn’t start check engine light came on. Left car with GM for 3 days couldn’t duplicate fault. Hadntvhappen sense but when’s the next time? It only had 5000 miles on it.
I bought my 2017 GMC Acadia from a GMC dealer back in November. It wasn’t until January when I started to experience this shifting into park issue. To me the GMC dealer did something to resolve this issue just long enough to sell it. I also own a Yukon and this is my 1st bad experience with GMC. If there is a class action lawsuits I’d be interested in learning how to get involved.
Purchased my 2018 Acadia back in July. Started having this issue in September. After three trips to the dealership to replace shifters and assemblies, the problem has been resolved since January. I pray it doesn’t become an issue again.
I had the same issue with my 2017 GMC Acadia. I had it for about a year or so when it began. I had no clue what to do when it first happened. I googled to find a quick resolution with shaking the gear shift. That did help but it was annoying doing that all the time. I took the vehicle to GM and told them about it. They were aware of the problem but said there was no recall on it yet. Thankfully I had a bumper to bumper coverage with my car inaurance or I would have had to come out of pocket with $1100.00, since extended warranty did nothing. I am definitely trying to get in on this action. GM should have just recalled and fixed it.
We own a 2017 GMC Acadia and purchased it with about 20k miles on it, we’ve only driven it about 15k miles and have started experiencing the issues with our Acadia, Denali trim, 4WD. It scares me because my 17yo daughter will sometimes drive it and several times could not get the vehicle to register it is in park and it will not turn off. This hasn’t been the only issue, the front sensor will sometimes think there is something blocking us and slam on the brakes when we are going 5-15mph. Fortunately it has not caused an accident.
Jason the stopping is just the auto stop. None are perfect as they can do this no matter the brand. Welcome to the future.
Read the a TSB I posted and your issue will go away.
It could be ss simple as adjusting the shift linkage underneath the vehicle! Probably not in correct spot as it is tightend together on the assembly line. Had similar problem with Cadillac CTS!! Dealer/ repair can put car on the houst with vehicle in neutral, loosen 5he nut on shift linkage rod to transmission and it should badically fall/ slide into correct position with minor adjustment!! Easy fix! Curious to know!!
Twice my Denali Acadia left me stranded due to the gear shift not engaging completely and leaving the dashboard lights ruining long enough to kill the battery, Then I had to tow my Acadia to get a new battery and some of the gear shift parts replace and it has happened about a year apart each time it was very disappointing to find out that it has not been recall after so many other have had to deal with this.
Not just 2017 gmc Acadia, the same thing happen to our 2008 gmc Acadia. We had it for about 7 years ago and it happened to us on several occasions.
I purchased a 2017 GMC Acadia on December 2019, I too have experienced the shift to park error, leaving me trapped at work, the grocery store, and home. It started about three months ago and it super frustrating! I purchased the under 20k miles. I just want it fixed!!!
People don’t realize that there is no more lincage or cables on newer cars. Your gear selector is just an electronic module that connects to bcm, and telling transmission what to do. I’m sure some software could fix it. Removing battery for a few minutes can fix glitcy modules, and weak battery can make modules to glitch. I learned it from my ram.
Some time in or around april 2019 our 2018 Acadia. Was doing that same thing the dealership changed the cable. It fix the problem. But if February 2020 while driving the car from the store our car just shifted into park crossing a intersection. Thank god we didn’t get into an accident. We were going about 20 miles a hour.took it to the dealership they had it for a week could figure it out. And said it may not happen for awhile. And just gave the car back. Now every time I drive home from work you hear the e brake engage. And disengage when I stop at the house. Dosent make you feel safe. I think theres something to do with the computer.
YES! I AM SO HAPPY I FOUND THIS ARTICLE! I have a 2017 Acadia crossover. Bought is brand new in 2017. When I first experienced the issue my dealership didn’t understand what I was complaining about but worked with me on it. Finally I was able to use them the issue, by then they had already been notified by the manufacturer that it was a known error and they were working on how to fix the issue. It became a recall and it was fixed. HOWEVER it was only fixed for two years. Now it’s happening again and the dealership wont fix it without me paying for a $130 diagnosis fee! I am happy this article says that the problem was not fixed on all cars. If I could piggyback on this lawsuit I’d do it. I have two little ones and there are times I’m stuck playing with the damn gears to turn the car off for 15mins.
I purchase my 2017 Denali Acadia 15 months ago and within a few months had the dealership replace the sensor portion of this error code. It was good for a few months, but now it’s does it periodically. I’m tired of this. My question is, Do the new 2020 Acadias have this issue? Safely is #1 and this is Unsafe!
I have had this issue and also an issue that when my vehicle shifts into second gear it “bogs” down sometimes hesitating when I’m accelerating. I have taken into the dealership to address this issue and they tell me it was a design flaw and can’t be fixed!
I bought a new 2018 Acadia Denali. I haven’t even put 20000 miles on it. Shift to park started this February. Took to dealership twice. First time in March and most recently this week. They said GM is aware of the problem and both original fixes did not fix the issue. They informed me that GM believes they have a fix due out hopefully in June! In the mean time they say live with it. Clearly they have no idea what that means. Live with my vehicle running for nearly four hours while I try to get it to register being in park?!! I’m hesitant to drive it anywhere for fear of it not turning off again. Which happens well over fifty percent of the time. Please HELP!!! I wonder how the Lemon Law would work in this situation.
I bought my 2017 GMC Acadia in October 2019. I had to take it to the dealership 3 times!! The sadder part is that my husband had to tell the mechanic that they already did what they were proposing to do AGAIN, so that they wouldn’t replace the part with the same part! Smh.
We own 2018 Acadia won’t lock in park most stops as u all know. Had fixed once with new wiring harness. 2 weeks later problem continues as before. We find pushing the shift button multiple times allows it to stop most times. We want in on lawsuit,this is lemon law problem and a safety issue!
You do realize it is in park the indicator just says it is not. It will not roll away.
Yes but it is still a safety issue. An indicator saying you’re not in park when you really are is confusing and will not allow you to just walk away while your battery goes dead wherever you might be or stress you thinking it can roll, how do you know? Why can’t it be fixed properly if it is the wiring harness which it isn’t because others say it continues after the wiring harness fix. I suggest it is in the release button push down mechanism!! Take a look at that GM!! A $35,000 vehicle should not have this simple of a problem and not be resolved, pathetic!!!
Chris you really lack in critical thinking here if this stresses you out.
#1 if it is not in park it will generally roll.
#2 Use the Emergency brake if you have any doubts.
#3 If you can not shut it off then don’t leave it. If needed carry a wrench to remove the battery cable If needed.
#4 Return it to the dealer or another dealer to have the problem resolved.
#5 if it was on so simple of a problem then why don’t you show them how to fix it?
The reality of all models and all brands is they can and will have an issue that will come up and it may not always be easily resolved. Vehicles are. Dry complex today and even a change of a bulb to the Wong one can set off a chain off issues with a body control module. I saw that one not long ago with a change to LED bulbs.
Today’s cars are using more voltage and computing power than ever and this is why GM and most other MFGs all are bringing out new gen electrical systems.
I had this issue, I know what it is like and yes it was an inconvenience but no one was ever in danger or at risk.
Do your self a favor and save the stress for a real problem. There are many people out there that would trade you a funky shifter for their problems.
Life is to short to waste worry on this. Just deal with it.
