GMC Acadia Class Action Lawsuit Filed Over Failure To Detect Vehicle in “Park”

General Motors faces a class action lawsuit brought on behalf of customers who claim GMC Acadia vehicles have defective gear shifters, which prevent them from properly placing the sport utility vehicle (SUV) in “Park” and turning the engine off.

The complaint was filed by Brandy Smith in the United States District Court Eastern District of Texas on May 14, alleging that the U.S. auto maker has known about problems with an intermittent gear shifter, yet has failed to offer a repair remedy.

Smith, who seeks class action status to pursue damages on behalf of similarly situated owners of GMC Acadia SUVs, alleges General Motors continued to manufacture and sell the vehicles for profit without offering a remedy, despite the known defect.

Smith, of Texas, claims she and hundreds of thousands of others who have purchased certain GMC Acadia models are often unable to shut off their vehicles and, to avoid battery discharge, are forced to resort to all sort of gimmicks to get their vehicles to detect that the shift lever is in fact in “Park.”

The GMC Acadia class action indicates Smith has been forced to repeatedly find new methods of turning off her vehicle, such as wiggling the shifter, shift it through its gears, and start and shut off the engine. Smith claims she has found herself stranded inside her vehicle at home, at work, at school, and at various other places away from home, unable to shut her vehicle off.

Despite Smith reporting the issues to General Motors authorized dealerships at least six times, she was told that since the intermittent defect was not noticed at the time the vehicle was inspected, no repairs could be made.

The lawsuit claims GM has been aware of the defect since at least May 29, 2018, when the manufacturer issued a Technical Service Bulletin warning customers that the vehicles may not shut off when the vehicle is put in the “Park” position.

On October 3, 2018, GM issued a subsequent announcement indicating the defect may be due to the “park switch in the transmission control (shifter) assembly not pulling BCM signal low to electronically show Park condition.” Within the notice, GM stated the defect can be corrected by replacing the transmission control assembly, yet has not offered customers experiencing the issue any remedy, nor have they issued an official recall campaign, according to the lawsuit.

The complaint details several related incidents which have been reported to the National Highway Traffic Safety Administration (NHTSA), all expressing concerns over how the vehicle must be left running, which poses a theft and drained battery risk that could leave consumers and their occupants stranded.

As a result of this defect, Smith claims the value, safety, and use of the vehicle are diminished, leaving the burden of the defects on the consumers, all while GM profits.

Her complaint presents claims General Motors breached its contract with customers and failed to provide repairs required under the vehicle warranty, among other allegations. Further, Smith alleges GM will continue to benefit from its unlawful conduct by selling and leasing more vehicles, at a higher price, and avoiding warranty obligations, while consumers suffer from the defect.

The lawsuit calls for GM to pay monetary damages to Smith and all other similarly situated consumers who either purchased or leased 2017 through 2018 GMC Acadia vehicles in the form of a refund of the full contract price, punitive damages against the manufacturer, and a recognition of the impacted vehicles for an official recall and repair campaign.

    I have a 2019 Acadia with he same issue. I took it to a GMC dealer and they did not take any responsibility. After arguing for hours, they offered to pay half of the repairs. I spent $240 to fix a problem that was not my fault!! GMC truly does NOT care about their customers safety!!!!!

  • ErickaJune 25, 2022 at 9:54 pm

    I’m experiencing the same issue and have for about 3 months. I bought the car 2 years ago and in my area in Michigan this is a known issue as to what the mechanic said. He has replaced several of these. Thankfully I do have a service contract but unfortunately will still be coming out of pocket.

    I have a 2010 Acadia that shifts bad and goes in reverse while in drive. I had the TCM replaced twice and that didn't help 2400 later I was told I needed a new transmission at 5000. I am single mother of 2 of a very small income and cannot afford that. Can I contact someone about this? I need help!!!!!

    Same problem here in Florida, now it leaves me stranded in blistering heat because it won’t turn on. I wish there was a class action suit in Florida.

    I have a 2017 Acadia, and it started doing this today. It left us stranded in 10 degree weather, no heat no nothing. Had to have it towed. Just no more yhan 2 weeks ago the starter blew. Had to have that replaced it's still under warranty...but still, it's ridiculous.

  • RogerFebruary 4, 2022 at 1:12 pm

    Had to pay $500.00 to replace issues related to shifter sensors on my 2017 Acadia Denali with less than 25,000 miles. GM should reimburse that!!

  • PeytonSeptember 21, 2021 at 5:35 pm

    Ugh! My 2018 Acadia has had issues twice with the shift to park message. Last time the dealer replaced a part and did not charge me. This time they are replacing the entire shifter and charging me $700+ this is not okay. It’s unbelievable that GMC is doing nothing about this issue.

  • LeesaSeptember 10, 2021 at 9:45 pm

    I have a 2017 Acadia and this is my second time getting this fixed. This is ridiculous that GMC will not recall all the vehicles and get this issue resolved. I am hoping to get a few more year and then trading it in for a different manufacturer!!!! I want in on this Class Action Lawsuit!!!!!

  • JessicaJuly 28, 2021 at 5:50 pm

    I have a 2017 Acadia that I leased in 2017 and then decided to OWN about a year ago. My car has recently begun the issue of not recognizing being shifted into Park. As well as other issues. Go figure.

  • NicoleJuly 28, 2021 at 2:37 pm

    I have a 2018 Acadia and have had the same Shift to Park issues and have been stranded a couple of times due to a dead battery. The transmission also just went out @ 80,000 miles and cost $5000 to replace. Was not expecting that in a 2018 vehicle.

  • LisaJuly 27, 2021 at 1:37 am

    I have a 2017 Acadia. I had this issue start in 2019. The dealer claims to have fixed the issue but it’s still happening. I was at the dealer today and they told me that they checked the car several times and found no issues. It literally just took me 15 minutes to get the car to turn off. How can I be included on the lawsuit because this is not safe to drive this way.

  • CHERYLJuly 16, 2021 at 11:42 am

    I have a 2017 Acadia and have the same issue. Until this week thought it was just me. That I was some how doing something wrong. How do we get included in the suit?

    I too am having the same issue with my 2017 GMC Acadia Denali. I have only had it a few months and it only has 15000 miles. Scheduled to go to the dealer to be fixed on Friday.

  • JerryJune 21, 2021 at 7:35 pm

    I just spent a little over $400 for the dealer to replace the shifter to correct the "shift to park" error. My Acadia was 3 months out of warranty. I hope to be reimbursed in the future should the class action suit go forward successfully.

    We are having the same issues with our 2019 Acadia and the shift to park error. I have to get it fixed soon bc it's stranded us several times. I am furious there has been no recall, but service bulletins to alert GMC service about the issues so they can charge us consumers to attempt the fix. How do we get in on this lawsuit?

  • KatelynApril 27, 2021 at 6:05 pm

    I own a 2017 GMC Acadia and have the shift to park issue. Had it fixed once under the recall and now a year-ish later it is happening again. It is absolutely frustrating and it can take a long time to get the car to finally recognize it is in park!!! I am often with my kids and can’t be dealing with this. GMC you need to make this right!

  • JamesApril 10, 2021 at 6:38 am

    I have a 2019 with 20,000 miles on it. The dealer has "worked on it" four times with no resolution. My next step is to let the mofo roll down the hill with a note on the dash to contact GM. Fed up with it! Took a chance on an American car and lost!

  • CynthiaApril 3, 2021 at 1:40 am

    I have a 2017 Acadia under 50,000 miles, shift to park notice started yesterday. Went outside tonight, lights on. Took several tries to rid this notice by starting the car repeatedly and moving the shifter back and forth. I live in Missouri, any class action lawsuits here?

The shift to park issue comes and goes but I can usually get it to park by turning car off in drive and then shifting to park. Sometimes I need to put on extra brake let car go forward without hitting brake then turn off car and shift to park.

    Having same problem on our 2019 with 42k on it. They said it would be $440 to fix it. How do we become part of the class action lawsuit as this is ridiculous to have to waste time trying to get it to register it is in park so I can turn the engine off. GM should be paying for this!

A week ago, I was experiencing "shift to park" message on the Driver Information Centre. The gear indeed was in park, & the "P" on the gear shift was lit up. After trying several times, moving the gear from P to R, then back to P everything shut off as it should. Then the problem persisted. The car is presently in the Service Department, & the Service Advisor informs me the entire gear shift assembly (if I've described it correctly) will be replaced. Obviously the problem showed itself to the mechanic. I did take out the extended warranty, so I'm hoping it won't cost me much if anything. Should I continue to have problems with the vehicle, you can be sure I'll get rid of it. Hopefully, the gear shift replacement will end the problem. Good luck to you all. I live in Canada., & from what I've read & learned, it seems this problem is widespread. I have a copy of a GM bulletin explaining the problem & suggestions as to what could be done (as far as repair is concerned) I took a copy of this bulletin to the Service Advisor when I took my vehicle in to have it repaired.

Just had this problem on a slightly older modle and the dealership cut ties and refued to honor written agreements or talk with us in late may. Is this why? They literally wont speak with us specifically following this problem.

The dealer ordered the part which took 6 months to come. I called often and they said the part wasn't in yet. Finally it came in and I took it in. The very next day after it was supposedly fixed it did it again. Did it everyday for 5 days straight. I called the dealer, they ordered another part. I waited a few weeks and got it replace today. No charge. If it does it a third time I want them to take this car back. They need to figure out this issue before someone gets in a bad predicament.

I assumed okay they will keep it. Next business day they never called me to even say it was ready. I had to call them! They told me over the phone it was covered by warranty but when I got there they said nope it’s 350.00 dollars! I never got an update on the vehicle to tell me they were going to put a new part on it. Anyways besides the terrible service at sisbarro I’m out $350 and and I can’t believe this issue has been going on for quite sometime that they can’t just issue a recall on it!

    I’ve had the issue since January 2020. The electrical unit in the shift housing console was replaced under warranty. 3 weeks later same problem. Both times the issue has caused my battery to die, now GMC won’t toe to the local dealer but wants me to commute over 1.5 hours to another dealership! Might be time to sell the GM and go with another company for a vehicle

    Had the same thing happen to me in January 2020. Have a 2017 Acadia and because the official warranty period expired in Nov 2019, they charged me $500 to replace the shift assembly, even though I still have less than 36000 miles on the vehicle. I even contacted GMC customer service directly and they offered no relief.

  • JessicaMay 23, 2020 at 2:57 pm

    I also have been stranded due to this shift to park issue in my 2018 gmc acadia. Im hoping it doesnt keep happening.
