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 bought an Acadia and this code started a few days after I picked it up. It has been back to dealers and the code doesn’t show. How do I get into the lawsuit? GMC should recall this and fix it free of charge. I feel my car is unsafe due to this issue.

Ryan or Maria
Same S-I-P problem. 2019 Acadia. 51k miles. $665 cutomer pay. Not recalled or covered by 5yr/60k PT warranty or X-warranty (switches and wiring not warrantable replacements.

Shanika
I will never buy another midsize SUV from GMC! I’ve had issues with every last one of them.

Yu
Have a GMC Acadia 2017, keep having shift to park, when I park and shut off my car. Dealer asked $665 to fix it. This should be a recall!

Patricia
I purchased my 2019 GMC Acadia last year July and have never had any issues until recently with the following problems listed: Service Parking Brake Service StabiliTrak Too be charged over $20,000 for a vehicle I have owned a year is frustrating to say the least, and I don’t know what to do. If I let the vehicle go into the Auto Stop mode at any time the whole panel lights up and the steering wheel tightens. It has died out on me 2 times and I have had the battery checked which is good and possibly a problem with the alternator. I wouldn’t expect anything to be wrong since this vehicle is still new to me. I keep up with all the maintenance such as new tires, oil changes etc. Please help if anyone is experiencing the same issues.

Idalia
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!!!!!

Ericka
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.

Debbie
Same problem

Julie
I have a GMC Acadia 2018 with shift to park issues. Warranty out in April and this was in May2022. I purchased my vehicle new in 2019. To get the vehicle fixed at Serra dealership in Jackson, TN. and cost was over $800 dollars. Called GMC and they haven’t done anything yet. I would join a class action lawsuit if there is one in Tennessee. I won’t ever buy another GMC and that’s all we ( me and my husband) have bought for many years! Not anymore!

Nichole
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!!!!!

Amanda
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.

Andrea
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.

Roger
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!!

Jamey
Same problem on my 2019 gmc acadia

George
My wife has a 2019, in the shop again in st.augustine fl for shifter. We just paid over 500.00 for first one and broke again. How do we get our money back?

Oscar
I started having the pork problem several weeks ago with my 2018 GMC Acadia, sometimes the car wont turn off and continues to alarm that it’s not in park, contacted the dealer and they are not aware with any problems with this vehicle??? I’m at my wits end I’m concerned that matters will get worst and I will be left stranded like other drivers, I hope someone on the email can help. Thanks for your tension

Peyton
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.

Leesa
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!!!!!

Jessica
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.

Nicole
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.

Lisa
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.

CHERYL
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?

SHAWNA
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.

Corey
I have a 2018 GMC Acadia and that shift to park issue is driving me crazy .I was late to work a few mornings because the battery was dead .It’s a big problem please help.

Jerry
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.

charles
my 2017 acadia denali shift to parn display appears weekly and car battery drains completely if not driven every day parasitic drain problem

Amanda
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?

Katelyn
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!

James
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!

Cynthia
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?

Teresa
Sign me up! My problems with my 2017 GMC Acadia Denali started a a year after purchase. My side sensors stopped working and dealership would not fix because I had a minor hit in a parking spot and the dent popped right out. But because the sensor is in that vicinity they wouldn’t repair even though I purchased expensive add on warranty. In January my drivers seatbelt latch stopped working. 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.

Linda
I have a 2018 acadia. Bought it used october 2019 with 32k miles. I have been having this issue off and on since i bought it. I finally had to drop it off today since yesterday i could not get it to go off. I tried to stop at the store on my way home but acadia had other plans for me lol. Finally got it to go off so i could lock the doors for the night. My extended warranty cover the fix of replacing the shifter assembly and harness. I pay a deductible of $100 for this. I now have 50k miles on it. Hope it does not fail once my extended warranty is up.

Kimberly
I am experiencing the same issue and when I go to the dealer, I cannot recreate the problem when I am at the dealership and now my car is no longer under warranty anymore.

Aaron
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!

erna
same problem here in Canada. not covered.

Paloma
My 2018 GMC Acadia is sending a shift to park issue and it’s so aggravating to sit in your car trying to turn off called dealer no recalls out of warranty taking it tomorrow to get a new shifter 500.00 dollars cost they need to have a recall on it if it’s such a problem fir everyone

Marilyn
Had same problem this past week with our 2018 Acadia. We took it to dealership and they fixed it. Two days later problem is back. Any class action lawsuits in Florida.

Cheryl
I bought a 2018 Chevrolet Malibu in early September 2020. 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.

Rose
I had this issue and I took to the dealer and they said it was fixed, but I just had an issue where my vehicle was in park and rolled out into the street with my granddaughter in the car.

Carlos
Have the same problems with ours we just bought a month ago 2017 Acadia

Mike
I’m trying to get my 2017 Acadia back into the shop for a second time for this issue. We were at less than 37500 miles when we had to pay $600.00 for the first fix due to it being out of warranty. Now it’s doing it again.

amanda
I have a 2017 acadia that bought new in January 2018. Same problem with shift to park and problem taken in twice to be fixed (did harness 2nd time) and now doing it again. Dealers unable to tell me how it can be fixed.

Karina

mamie

Amy
I have just had to pay for the repair at my local dealer. They are saying the shifter and harness are not part of the drive train. How is that possible? You can’t drive the car without it.. How do i become a part of this lawsuit?

Jennifer
I own a 2017 GMC Acadia Denali with 55,000 miles and I have an appointment to bring it in to the dealership on September 24, 2020 for shift to park issue. I am so frustrated with this vehicle because I just had it in the shop less than a month ago because my air conditioning stop working and I had to pay $1,500.00 and I was without a car for 4 days. This is ridiculous.

WA
I have a 2019 Acadia Denali and just began experiencing this problem with <25,000 miles on the vehicle. Definitely not just a 2017-2018 problem. Super annoying. Can't get an appointment with the dealership to fix this until over a week from now.

Bob
My 2017 GMC Acadia with 16,000 miles has developed a problem when I put it in park. A light comes on to shift into park. I don’t want to get stuck.

C F
I have a 2017 GMC Acadia and I live in Canada and just got this exact problem fixed! I’m lucky my veh is under warranty so it cost me nothing but I was definitely not pleased about being stranded.
