A class-action GM transmission lawsuit has hit a snag after a judge dismissed certain implied warranty claims made in the filing.
Five separate class-action lawsuits filed against General Motors over alleged defects with its eight-speed automatic transmission were consolidated in a Michigan court this week, according to Car Complaints. In the process, the judge presiding over the lawsuit, Judge David M. Lawson, dismissed claims related to implied warranty for all plaintiffs that fall under the laws of Alabama, Arizona, Connecticut, Idaho, Kentucky, North Carolina, Tennessee, Washington and Wisconsin. Another claim related to class wide monetary damages for a sole plaintiff under the Colorado Consumer Protection Act was also dismissed.
Numerous class-action suits have been filed against GM over its 8L45E and 8L90 eight-speed automatic transmission. Plaintiffs claim the eight-speed automatic transmission will slip gears, shift into gear aggressively and also cause the vehicle to shudder or jerk. Plaintiffs have also reported the transmission will lead to delayed acceleration and make it more difficult for the vehicle to slow down.
GM has argued that these claims should be thrown out, as its express warranty only covers defects that relate to materials and workmanship, and not design defects. The suits claim that all 8L45E and 8L90E transmissions experience these problems, which implies the problems are related to a design defect instead, the automaker said.
Judge Lawson will allow other allegations in the suit to proceed, including certain other claims related to implied warranty. The judge also acknowledged that the complaints put forth by plaintiffs could be consistent with either materials/workmanship defects or a design defect. He also did not dismiss claims that GM knew there were issues with the eight-speed transmission before it put affected vehicles on sale, saying “plausible inferences may be drawn that GM had substantial knowledge about the looming problems with its new transmissions before any of the plaintiffs’ purchases were made.”
The full list of affected vehicles in this newly consolidated transmission lawsuit includes:
- 2015-2017 Cadillac Escalade

GM can’t build transmissions or interiors!
GM recommends a triple flush with a different transmission fluid. The old fluid is hydroscopic and absorbs moisture. If your car is out of Warranty you are stuck with a $900+ bill. GM put the wrong fluid in. They should pay for the fluid flush, new filter and gasket no matter the mileage. Like mine a 2017 with 13k miles before the problem began.
I have said before so many times, I think this is fraud.
I think GM is committing fraud !
If you sell something saying X and X does not happen, how can you continue to sell that product !
And the warranty ! WOW, how does GM continue to get away with not honoring their warranties ?
And the dealers, dealing with these, WHAT A JOKE !
GM has little power over these dealers, and when a customer has troubles, it is just a HORRIBLE EXPERIENCE !!!
!!!!!! HORRIBLE !!!!!
HOW THE H3LL is a design flaw, or ” known faulty ” design NOT a warranty issue ?
Let me say this, IF this transmission shift was human injury related, the government would call the design defect the problem and demand a RECALL !!
Yet when its just the customers money, or lively hood, the government doesn’t care one bit !!!
I wonder how come we have government problems in the good old USA !
The customer has no rights !
Yet GM can commit fraud and steal from the consumer !
Isn’t there a consumer protection agency ?
Trump probably fired all those people also !
Your Liberal Democrat ways have finally shown through. The only work I don’t think you used that is a staple of the Left is Propaganda. You want to write a reply and include that? It is a shame this country is being ruined by the far left, wearing rose colored glasses and taking their participation trophies thinking everyone can have everything and no bad can be done in this world.
WOW !
Commonsense !
Your snowflake panties in a bunch are they ?
If you have not noticed by now , you are losing all the way around on this GM 8 speed junk transmission !
GM however is still winning as our laws, are put in place in our country to protect fraud and corrupt companies !
Even back when GM went bankrupt, the government was right there to bail them out !
This is why our country is at the brink !!
The REAL people in this country, have no where to turn !!
Just like this lawsuit, GM CLEARLY knows they have produced junk here !
There are HUNDREDS of TSBs on this GM 8 speed junk transmission !
And even in this very lawsuit, GM is saying a DESIGN FLAW, is NOT a warrantable claim !!
This will play out just like our federal government, GM will push the people, the customer, right up to the brink, before GM does the right thing here !
And all for the mighty dollar, going to the DO NOTHING population !!!!
Commonsense,
I am truly sorry I hurt your delicate feelings !
Laws are to protect you from making a bad deal? Not what I thought…hmmm any wonder people scream, ” I’ll sue!”
GM should NOT have been bailed out.. just like Fiat buying Chrysler, or further back when Mercedes Benz bought it, GM should have been sold off and the investors PAID. Yet they the stockholders lost their money.. It was a sleezebag operation and it emboldened GM to freely screw the very people who not only bailed them out, but continued to buy their bullsh!t products
I agree. I don’t see what Trump has to do with a company manufacturing a car with a major design defect. I almost feel like eventually they will blame Trump for the weather, too. Politics aside, this is exactly what a lemon law attorney is for. You don’t even have to own the car anymore to be entitled to a full recovery. I work for Law Offices of Issac Kohen, and we serve all of California. Initial insults are free and we bill the car company once the case settles. Our clients keep their settlement with no hidden fees. If anyone here lives in California and has questions, feel free to call me to discuss. 310-775-3678.

He only fired the ones who were sleeping on the job.
Why are you blaming Trump? You’re just showing your ignorance and hate mongering.
The day I left the showroom my 19′ had issues with the transmission. They said as long as the light isn’t on, GM will do nothing.
My 2016 camaro the transmission it’s got a shutter in it and a very hard shift.. is GM got a recall on this. What I understand is that this is a very big problem in many of Chevrolet Camaro and other vehicles also… what is going on are they fixing the problem . It needs to be fix
I joined this lawsuit. I have a 2017 Denali crew cab truck and it has had the “shudder” in it since I bought it. It also downshifts hard and clunks when it does. Dealer says he cannot duplicate my complaint so they won’t fix anything. I ask if he drove it and he said his mechanic did and said it was fine. I have taken it back 3 times and still won’t fix it. I have had enough and I want something to happen. GM needs to replace trans mission or do a buy back. Every penny I spent on this truck should be paid back to me.
How did you join the lawsuit? Our transmission had a catastrophic failure and needs full replacement. 2015 GMC Sierra
It is never in your interest to join a class action, and you are automatically included unless you opt out. The lawyers make all the money and the victims are left most of the time with nothing more than an extension period to their warranty. You actually WANT to find a lemon law attorney, have them opt you out, then file a lawsuit on your behalf separately, I work for Law Offices of Issac Kohen and we specialize in lemon law. We serve all of California. Every state has they own laws, so it is imp to find an attorney in your state. I’d be more than happy to discuss any questions. 310-268-7802
Do you have a law office in Milwaukee we have the same issue with our 2017 denali xl
414-517-9669
What was your outcome?
My 2018 with 36k miles on it has the exact situation unfolding.
Dealer service telling me there is no issue, they can’t duplicate the problem.
How can I join the lawsuit?
Thanks
How do you join the lawsuit claim? I have a 2015 Sierra Crew Cab. 118,000 miles…. my transmission just “went”…. it’s in the shop. They said 7-8K for replacement and it was giving me trouble since around 90 thousand miles. It has not been accelerating or switching into gear properly for a while now. Thanks Chris.
Haha, 118k and you want to join the lawsuit? Jesus what is wrong with people thinking they are entitled to anything and everything. At that point you don’t, no lawyer will want to include your case in with those having problems early, you got good use and mileage out of it. Should have gone more but who knows how it was treated, driven, abused or lack of maintenance was done. I had a buddy who he went through two 4L80’s, not because they are at all a bad transmission, actually quite the opposite, but because everytime he shifted from reverse to drive he did it at 5 mph and not use the brake. Abuse and lack of maintenance doesn’t equal a lawsuit, like the numb nut that hydro locked his Rubicon early and wants to blame and sue Jeep even though he abused the crap out of it hitting massive mud puddles at higher speeds.
Get it repaired and move on, that 118k isn’t the norm but on the lower end of normal life, most with good care and maintenance can easily eclipse 200k but it all depends.
You are exactly correct. A lot of people beat the crap out of a car or truck and complain what a piece of crap it is. I have a gmc van with 4l80e with 270 thousand miles on it . It is extremely overloaded. I push it hard at times but I don’t beat it to the point that the transmission over heats. It has only had one fluid change at 177k.
I find most transmission failures come directly from the way they are operated. Especially plowing and not using low range, the trucks are equipped with it for a reason.
The 4L80E was a great transmission!
^^Tens of thousands of complaints.
Did anyone find out the best way to join the lawsuit claim?? Private lawyer vs. being part of the Class Action Lawsuit without an attorney. I was contacted by a law firm. That is how I found out about it. My 2015 Sierra has shuddered since the day I purchased it brand-new. It also shifts hard at times. I took it in twice while under warranty and the dealership told me it was normal for this type of transmission. My current mileage is 60,920.
I just had the transmission go out on my Chevy Tahoe at 110,00 -2016. Terrible! This will be my first and last Chevy purchase, back to Toyota or Honda.
Now you know why GM went bankrupt! Let’s try that again without help from our government…
Sorry about your GM transmission troubles people. I really hope GM takes accountability for this issue. I guess a Toyota Tacoma or Tundra would have been a much better choice in my opinion. Good Luck.
Yeah like those are trouble free, especially the Tacoma, they have their own transmission issues that sent people to trade them in.
I think its past your bedtime.
I thought that truck transmission were made at the Ford general motors plant in Mexico I have a 8-speed in my Buick regal but it is a Toyota transmission made by aison
I have a 2019 Silverado that jumps into gear and does the exact same thing as described in this article I’ve taken it a few times to Chevy dealership , and was told this is normal , I beg to differ we have owned Silverado for 14 yes now have had 7 of them this is the first one to ever do this
MINE TOO, AS DESCRIBED AS ABOVE, 2019 SILVERADO 8000 MI , DEALER CHANGED FLUID,,,, NO HELP ,, LIFE LONG GM CUSTOMER…
‘” FIRST” GM PRODUCT I AM DISAPPOINTED WITH,,, PUT MY NAME ON THE CLASS ACTION LAWSUIT
PS: I KNOW CAP’S ARE ON
I have a 2019 Chevy Silverado as well and it’s doing the same thing, who do we contact for this class action lawsuit? GM just offered me a longer warranty.
Yes, that’s what they do rather than to fix the faulty transmission. Year after year after year with the same old bs. They must think car buyers don’t speak to each other.
Have a 2020 silverado , same problem . Say it’s normal ???
It seems like just about everyone I know with a chevy and GMC truck has had some sort of transmission issues. Luckily I only buy FORD, And with 96,000 miles on my 2017 F150 Lariat FX4. ZERO ISSUES.
Funny, the only person I know with a GM failure (many I know drive them) had transmission problems and it was because of abuse as noted in a comment above (changing to drive from reverse with out the brake while moving). Other than that of all our years of GM not a single transmission problem. 4 speeds going to 250k while towing a boat at its limit in an Astro van, buddy had the 4L60 in his Tahoe for 290k when he traded it in and it was trouble free. None that we have had any issues. Most don’t, just like most brands. I know a few people with Fords and a few that have moved away from them, some trouble free while others because of issues or failures. Seems the Ecoboost is the big failure point, not sure I would want my engine to be a concern even if I had a good transmission. The old 5.4’s had spark plug issues, one of the generations of power strokes was prone to failure as well as a spread of the 2.3 ecoboosts. So not sure I would boast about transmission issues when their engines are lacking…
Mmm thats funny I have 2019 Chevy Silverado when the truck is at an idol the transmission makes A Ticking time bomb sound. At least i hope thats normal lol. there was a time that mine as well down shift real hard like if some one hit me form behind. Scared the crap out of me.should I have buy a Ford.? Lol
I have a 17 Sierra SLT 5.3 w / 8 speed transmission. I complained about the irregularities everyone has mentioned and my dealer was very understanding. Flushed and changed the trans fluid and it’s much much better. Will most likely buy the refreshed Sierra with a 10 speed. Thanks
Is it to soon to list for 2020 colorado or did they fix the problem after the 2019
They came out with the new ATF fluid in around spring of 2019. Its just a band-aide. Some 2020 models are having the issue as well from what Ive seen. The fix for them is a new torque converter. Not good to say the least.
Had my triple flush at 10 000, then a converter at 15k. Still fouled up. Waiting to see if gm will do a buyback, but after seeing the court decision I believe gm will give me a 1 finger salute.
Its not Just the 8 Speed. I have been through 3 4l60e Transmissions in the past year on my Chevy Silverado. GM has NEVER got a Tranny Right! Sorry to all you new owners. Hopefully you all get help with your troubles. I know how it is ..
Come on, 3? If that isn’t a troll agenda… Ok, I can play this game it is easy to on the internet. I had an engine, two transmissions, 1 transfer case and 3 axles needing to be replaced on my Toyota in the past 6 months, don’t buy Toyota! Don’t get me started on the trouble my F150 had. See, easy to say what you want, not a single person is going to believe that…
We have three GM trucks and two of the three had transmissions replaced due to failure.
2014 Silverado was slipping and completely failed 4k out of warranty. The dealership stated I shouldn’t have followed the GM guidelines on service because everyone knows its wrong and wouldn’t cover it. Took it to a transmission shop and they refused to use the same year transmission and dropped back a version due to the main valve being the size of a ballpoint pen and its the biggest joke they’ve seen. The truck has over 200k now on the replacement transmission.
2016 GMC Seira had sudden transmission failure and died on the road 3k out of Warranty. GM wouldn’t cover it but fortunately I purchased it used with 20k on it from a Ford dealership and they covered it.
Anyway the third truck is a 2020 GMC and yeah, I should have purchased a ford because it sounds like they still have design flaws. Hey GM, maybe it’s time to fire your engineering team and while you’re at it, fire the team that designed the new trucks to dent if someone leans on it.
Hey the Dynaflow in my 63 Buick working great!
In or out of warranty, a flush and fill with the latest recommended fluid (3rd one) makes a big difference. My ’16 Sierra with the 8l90 shudder is “almost” perfect after the change. Started at 85k miles. Now at about 103k. There is a TSB out on it
People underestimate the benefits of changing transmission fluids more often than the maintenance schedule says or trying compatible fluids if there are issues. Some might say that it is a bandaid fix, but if you are out of warranty, it may keep you from having to replace the unit. Then again, it could keep the transmission working within specs and prevent it from premature wear or simply self destructing.
Trying other ‘compatible’ fluids can work. Generally OE fluids are pretty good, but there are other premium brands out there that will outperform the OE offerings.
My 17 as camaro had the shutter issue at 30k they flushed the fluid an it’s been perfect ever since. I think they just upgraded the fluid to something more performance driven.
My 2016 CT6 has a glitchy transmission. I have to drive gently so it doesn’t jerk into gear.
Another thing, isnt it weird to have three different transmissions? GM should just make the ten speed standard across the full size truck line.
Had a 2018 GMC slt 6.2 eight speed, same problems, took it in four times called GM twice, they said get a lawyer, so i called Lemon Law, they got me $2750 for each of us, bought a RST 6.2 10 speed, it is a lot faster, great trans.
A lot faster?
2016 Denali 6.2 8speed 5733lbs 0-60 in 5.8 1/4 in 14.2
2019 AT4 6.2 10speed 5466lbs 0-60 in 5.8 1/4 in 14.2
2019 Denali 6.2 10speed 5595lbs 0-60 in 6.0 1/4 in 14.4
It is the same or a touch slower it seems with the added shifts. It has been well publicized the 10 speed in many tests was a hair slower than the 8 speed, seems the larger amount of gears is a diminishing return as it slows it down with added shifts.
Hi everyone my name is jose and yes is really bad I bought a 2019 Silverado and I spent a year well over a year talking with GM and the dealership and I also have videos whit my problem. They brought a GM ingenier to solve my problem and even he could not fix my truck.by the end they give me a 2021 Silverado with 10 speed transmission and so far is been ok with it good look all of you
2019. When I go from reverse to drive it delays then slams into gear if you don’t wait an extra couple seconds. On a busy road, it’s a problem. Since the day I left the dealership, I’ve been back to complain 12 times. I opened a case with GM and they blow me off because the computer doesn’t register a problem. Dealerships are now saying the same even though the mechanics know it’s a huge issue
My dealership refuses to do anything about my transmission shift problem 2019 Canyon It’s a darn shame when a corporation Can get away with this wish I knew which way to turn The dealership will never get my business again being that day have given me the same and return damn it I cannot buy a vehicle without getting screwed only in America
Well you should have bought a Honda pilot or Honda Odyssey their problems transmission problems they only lasted 30,000 miles all the way up to 2010 Google it
I’ve complained about the 8-speed transmission since day one of buying my 2017 Sierra 5.3L. The truck jerks so bad you feel like you’ve been rear ended sometimes. It’s mostly downshifting into first gear when driving around slowly. The Dealer gave me the run around 4 times in the first 15000kms saying the truck had to learn my foot(the way I drive) and I gave up because I don’t have the time but it still has the issue like day one. I’m at 90000kms now and it’s just as bad or worse at this point. I sold my 2008 Sierra that had 400000kms on it with the original transmission that shifted smoother then this garbage. I’ll never by new again because of this. I spent 70k on this truck for nothing but problems and then get treated like it’s all my fault the hole time. Please GM let me know what you can do to make this right until then you’ve lost one of the largest fans you’ve ever had. I have 6 vehicles that are all GM’s and I’ll be focusing on changing them for different manufactures.
So you currently have 6 GM vehicles that are trouble free, have had years of great vehicles but 1 issue which isn’t that bad as you have been able to drive it for 90k and you want to switch brands? Ok, good luck with that! The grass isn’t always greener… Sucks you have had issues but sounds more like a dealer issue.
BTW, I would never buy a used truck. Too often they are modded horribly with stuff that wears out parts then take it off and the next owner has to deal with the repercussions. All these large leveling kits, wheel spacers and large off set tires just eat up suspension and drive train parts, wheel bearings and paint. The last thing I want is not knowing the dufus before me put on a 2.5″ level and wide off set wheel’s that peppered the paint, wore out the wheel bearings early and ball joints and CV axles are on their way out down the road well before they should. With the high prices of used trucks and the deals on new I will never buy a used truck. Having a warranty is fantastic, knowing what has or hasn’t been done to the truck is great as well as the maintenance records that I know of. You do you, but used isn’t a deal…
Hmmm Commonsense is your real name Mary? LOL Maybe you just need a tissue.
This common sense dude sounds like a douchebag that doesn’t know come here from sick em … If you actually turn wrenches then you can talk !!
I had an Escalade with the 8 speed transmission. When cold, it would sporadically slip. I used my phone to record a video showing the tach a 3000 rpm and the speedometer was less than 5 mph. The dealership changed the transmission 3 times. After about 16 months and 60 days of the car out of service, I went lemon law. I got my money back from gm. I loved the truck and the dealership really tried, but that 8 speed tyranny is garbage and dangerous.
Have a 2019 gmc trans is junk they said the recall to change trans module. Took it back because it was worse than before I was told it has to learn how you drive 60,000.00 for a truck and the this is junk 15000 miles it sits in the garage don’t drive it. Dealer says it normal ford would have been better
My 2017 Sierra had all of the same problems. The scariest was twice at 55 mph the trans started shaking so violently that I had to pull over because I thought something was going to explode. The trans flush didn’t work for me and ultimately my dealer said there was nothing more they could do. I ended up trading it for a 2019 F-150 with the 10 speed that I’m very happy with.
I tell people all the time if your looking at a Silverado skip the 8 speed auto and instead get a lower trim with the 6 speed or a higher trim with the 10 speed. Naturally GM makes that as hard as possible with the 2.7T which is 8 speed only or making you buy a Trail Boss or High Country to get the 10 speed on the volume 5.3 engine.
How do i get in on this lawsuit had to replace mt transmission on 2016 Silverado was over 5000 now behind on bills
Did read that right, gm said its transmission should not be covered because its a design defect?
WTF! They are trying to pull the same crap they did with wheel failures on the C7 corvettes. Claim the wheels cracking and breaking is a design flaw and therefor not covered by any warranty. Now since that worked they will try it with the transmission.
I’m waiting to hear back about a buyback, but now I see why they are dragging their feet, waiting to get a pass on this one too.
Well, be damned if I buy another corvette!
Go get u s ford, I been have a be f,150 same transmission tho gm used 100,000 miles on the 5.,0 engine been troub free on the entire time very happy
If a Chicom leader were sold one of these someone’s head would roll. literally. This is how GM has treated it’s loyal customers for decades and it is the reason they will fail again. C/mon Barra, own your product failures and take care of your customers or lose your customers. Toyota has made a killing off your design failures.
10k miles on my ’18 Sierra SLT Premium Plus, 6.2L, 8-speed. At 3k miles, I started getting a shudder, especially around 50MPH that continued to get worse. At 5k, brought it in to the dealer, they did a fluid swap to the new Mobile One fluid designed for this problem.
5k later and zero issues since.
2015 Yukon had transmission solenoid replaced under warranty and from that point forward the vehicle never shifted correctly. GM tried to reprogram and charged me $400, which had no impact on the shifting. They said it was normal and nothing more could be done. Last GM I’ll ever buy (this was the beginning of $10k worth it repairs, including a top engine rebuild.
2019 colorado trans shudder problem solved with fluid change.gm had the same problem with the allison trans when they designed and built not the best trans made.
This common sense dude sounds y a douchebag that doesn’t know come here from sick em … If you actually turn wrenches then you can talk !!
About time Gmc fans got smarter go buy a F150 way better truck more reliable & more power. Lol.
Bought a 2020 silverado with 5.3 and 8 speed transmission. When you take off some time it feels like it’s slipping and then bang into second gear . Also if you take off it shifts very hard into next gear . I was a mechanic and this is not normal . Took it to dealer and they said they all shift like that . This is not normal !! Anyone else with 2020 have this problem ???
I just brought a 2020 Silverado the truck shifts hard also. GM knows they have a problem never again will I buy a GM.(DON)
I have a 2018 Chevrolet Colorado 4 x 4 3.6. It has the 8-speed transmission. I think it’s a thing of beauty! It really utilizes the Rev range of the engine perfectly. I have none of the problems that anybody’s mentioned. I think Chevrolet is right they should throw it out.
my 2019 colorado basicly had a shudder right from new and also if you watched and listened close the engine rpm. would vary aprox. 50 or 60 rpm at the same mph. i confirmed this also with a scan tool. complained to dealer did a trans. flush was told mobil 1 synthetic atf was put in… that fixed it … BUT i have since been reading and seen a chart where the mobil 1 atf doesnot test to good against other brands … my first choice for replacement would be ams oil… HAS ANYONE PUT A LOT OF MILES ON THIS TRANS WITHOUT ANY ISSUES AND /OR USED A CERTAIN BRAND NAME OF FLUID WITH AND/OR A AFTERMARKET ADDITIVE or does that not help this transmisson
I had to get my transmission rebuilt the cluch was burnt out after ten thousand on it after I bought it with 20000 miles
I bought a 2019 limited last year which was a 2019 that was the prior body style. I notice mine shifted hard for a little while when I first got it. I also noticed that this hard shift always and I mean always corresponded with when it would shift and at the same time go from v8 to 4v mode. But it hasn’t shifted hard in the last 10k. That also said I have never had to replace a transmission in any vehicle I own so we will see if this is the first one that gets one.
Almost got killed in my 2017 Escalade. Went to git the gas on a intersection moved about 5 ft and tranny slipped in the middle of the intersection. On top of that every time you put it in gear the tranny would bang so hard I thought I got hit or hit something. I was in the shop ever 2 weeks and kept getting told that’s how they are supposed to be.
I have have a lot of GM trucks over the years.
I have always heard of all these transmission problems. Most of the problems are caused by the way people use them. They drive harshly don’t use low range on 4 wheel drive models when plowing. I have a Savana 3500 cut away with the 4l80e I bought with 25000 miles on it. I heard a lot of bad things about that transmission too. My van is overloaded and weighs in over 15000 pounds on 12000 chassis . I never changed the fluid till 170000 miles and as hard as I push it the transmission still works fine at 272000 miles. My 2010 Silverado with the 6L80e has 215000 on it it acts up once it while but I need the change the fluid. I bought I used and I doubt it has ever been changed. I have a friend with a 2016 Silverado with the 8 speed he said it acted up but at 75000 he changed the fluid and at 105000 it hasn’t bothered since. GM may have its issues , but it won’t stop me from buying another Silverado or Savana Van.
After reading lots of comments I can’t help but to mention that my 2006 Dodge, with 191,000 miles has had no significant failures of anything. Not the 5 speed trans, the 5.7 engine with the dreaded cylinder deactivation, nothing. My $80,000 2017 vette didn’t make it to 10,000 before it had trans issues. Now GM is trying to discount it as a DESIGN PROBLEM not covered by warranty. What a chicken $hit cop out. Im hesitant to try to sell it and move my problem to another in my corvette community.
GM, step up and make this right.
I bought a 1500 Silverado with 24k miles. Tranny went out at 28k. I have since changed out a whole wheel bearing, engine mount, boot, “fuel system cleaning” and now have to change out CAT. I’m at 32k.
I am 73 years of age and 90% of all the vehicles I’ve owned over the years have been a GM product. AND THIS WILL BE MY LAST and not because of my age. I live in Canada and own a 2018 GMC Canyon with 30,00 miles. The transmission is acting up when I put it in gear it has a long pause before it kicks in. One GM dealer says I have the wrong trans. Oil in it and needs to be replaced with Mobil 1 Blue label. They want $800.00 for transmission flush. Two other GM dealers say they have not heard of the wrong oil being put into these transmissions ?? If GM put the wrong oil in my new truck why should I have pay to take it out.. I read about the class action lawsuits taking place in the US and the GM dealers here say they know nothing about it. If i don’t pay the $800 bucks for the flush and I need repairs the warranty will be void. that is complete blackmail or fraud. I hate dealers that cannot be honest. Suck it up GM and admit your guilt for once. This why I will never ever buy another GM product.
How do you join the lawsuit? Private attorney or wait on results of class action? Have had transmission issues since bought my 2015 Sierra brand-new. Shuddering and hard shifting. Dealership told me this was normal for that type of transmission.
How do we join this lawsuit? My 2017 Sierra shifts horribly.
2016 gmc sierra I bought is a lemon! It has a shake when driving, oil lifter problems, ac problems, and at 80,000 miles the transmission went out and they want me to pay $5300.00 to fix a problem that gmc fkn knew about!!! Never will I get another gmc or chevy product!!! I purchased a lemon!!!!
2016 GMC slt, 5.3,8L90. 29,3xx miles. It’s driven mostly by my wife and well taken care of. Started a mildly bump of down shift into first around 6K miles we took it in thinking it was a brake problem as it only did it while applying the brakes and at a very low speed. The service manager at first said it was probably the computer learning how we drove it. At around 29K in traffic it slammed into first at stop lights while 40 miles from home. This got my attention. Took it in to dealer again after a few tries it finally did the hard downshift while the service mgr was with me. Took it in the next morning and get a call from Service that we need a new transmission! We live in a rural area so I had no idea there were trans. problems. The truck was at this time 2 months beyond the warranty on the drive train but many miles short of the 50K warranty. When told I would be responsible for the costs I balked at that and found out what is transpiring with these transmissions. We are currently waiting to hear from the factory regarding who bears the cost. All I really want is to have the trans. fixed. apparently this isn’t as easy as it sounds. Does anyone really know what the fix is? Because there are so many different symptoms I wonder if the engineers have looked at the one common item across the board that is the computer? We have other vehicles to use as this one sets in the garage so being without it isn’t a problem but we really like the “cowboy Cadillac” and would like to have it for use. Our dealer is ordinarily very helpful and usually goes the extra mile so I wouldn’t enjoy having to sue to get this fixed or as a last resort replaced by a different brand. Would love to hear from someone who knows a genuine fix for this problem.
This Judge must have been paid off, because this is far above even a warranty issue, it is a straight up safety hazard. This problem causes all sorts of unsafe behavior, from loss of control to even loss of braking. It is very unsafe. I cannot drive through a Drive-Thru without almost rear-ending someone because the transmission takes over and the brakes go hard as a rock. The problem also causes severe clunking in lower gears while accelerating/decelerating, which can feel like you’re being rear ended, causing major jerking and lurking with the vehicle. Further compounded if towing. It also presents itself as a severe vibration, making steering at times unsafe.
I have a 2021 Silverado RST 8 speed. 2k miles and about to take it back to the dealership again. The truck sometimes lunges forward and its scary especially on the highway.
I purchased a 2017 High Country brand new with 6.2 and 8 speed transmission. Have all of the issues everyone are having. Went through the flush routine, then a new temperature sensor and another flush and finally reprogrammed. Guess what still shifts hard. Dealers have been trying but don’t think this transmission can be fixed. I usually keep vehicles a long time but this one has me worried. Don’t think this chevy will make it. They will find a fix when warranty is up and cost comes out of my pocket.
I’m on 4 transmissions going on 80k miles. Every transmission has had problems on day one so obviously there is a problem. I was told the clunking noise was normal. The dealer had my truck for 183 days in 2019. I’ve owned the truck for 6 years now and literally has been in the shop for a third of it.

I think someone is paying off some judges.
look what is running gm at this time
I have a 2019 Silverado, just about to hit 11k miles, already had transmission flush, just put in shop for clunking, only vehicle I have ever bought new, been issues after issues, initially rear window leaked, now 2 issue with a major component the Transmission, leaves a sick feeling.
I think it’s crazy earlier models of the Colorado aren’t on here. I’ve heard numerous people complain about their 2015’s transmissions going out. I just had to replace my transmission on my 2016 at 98K. It started slipping and making noise around 60-70K.
Seems many comments are missing, there were thousands before, now just 94….
Anyway, I paid the $400 to get the Mobil Blue flush. Truck rides VERY smooth now on the highway (shudder is gone), but it did nothing for the low speed clunk when shifting. Since I normally don’t drive at low speeds I’m just going to live with it for now, because everything else on the truck is perfect.
They don’t cover design flaws? But isn’t it your design?. And it sounds like it’s not just 1 in a thousand cases. It’s more like every other one.
I have a 2019 chevy express van 2500 with this transmission. It’s slipping and vibrating as I drive it it has 58,000 miles on it and the dealership in my area is backed up with work I need this fixed asap as it’s a van in my plumbing company and with out it my business goes down. Can’t make a living with this kind of van. Can I take it any dealership?
Anthony; You may be in a pickle, I believe the dealers are dragging their feet in able to cause frustration as they did in my case. I finally paid for the fix which was very similar to yours. In answer to your question of taking your rig to a different dealer, yes you can. Any dealership is obligated to do warranty work but there’s no time specified as to when. I believe GM is stalling until the class action suit is settled. We may all be gray and crippled before that happens.
Have a 2018 Canyon purchased new, had a few hard shifting issues that comes and goes. (90,000 km) dealer says need a flush and add correct Mobil1 blue label only. Dealer claims original oil is wrong oil. Dealer is charging me $800,00 for a flush ??? I told them I refuse to pay that price for something that they did by putting in the incorrect grade of oil. They tell me every 50,000 Km you need to flush it and if you don’t your warranty is void . My old 2002 GMC 1500 has over 730,000 km showing and has NEVER had a flush. Go figure. I believe if the incorrect oil was originally put in and now they want to charge $800.00 to flush it or the warranty is void this is a clear case of fraud or maybe even blackmail. In Canada this truck comes with a 160,000 km powertrain warranty not sure about the US models.
I have a 2018 Denali (57k) with every option available, and like mostly everyone on here on here, I too have the same issues with the 8 speed tranny eg. clunking at low speed gear shifts etc. My truck is going in to get driver side power step repaired with new motor for it, and they are suppose to change the tranny fluid at the same time, to the new improved fluid. Maybe it was good that I got sucked into the extended up to 7yr warranty. Just hope this solves the problem. I too think Mr. or Mrs. Commonsense needs to stay out of this conversion if he/she isn’t experiencing the same issues. IMO
I have recently experienced issues with my 2017 Midnight Edition Silverado 1500. At approximately 73,000 miles: complete transmission failure. I have never put a great deal of stress on this vehicle. Please be advised gm sorta admitted they have known about this issue and are addressing on a case by case basis. The dealer servicing has indicated a root cause of “just bad luck” and “shrapnel bomb in your transmission” .. estimated repair costs 5,300.00. My issue occurred while the vehicle was in motion and while at a low speed .. I could have been on a highway .. I could have had passengers. Be aware of the operating state of your vehicle and communicate issues so the manufacturer can hopefully resolve.
Regardless if you believe it’s a dealership issue, a manufacturing issue, or whatever you wish to call this problem, we know it exists. At the end of the day, I shouldn’t be driving a $90,000 truck on the highway feeling like I’m inside a protein shake bottle. This is unacceptable. It’s quit sad that my wife would rather take our 2014 Dodge caravan to go on a long trip because it rides smoother than my $90,000 Silverado LTZ. (I have to agree with her). GM is trying very hard to put a Band Aid on an amputated injury. I’m extremely disappointed with how they are dealing with this issue. I’m clearly going to take my loss on this one because apparently GMs lawyers are great at what they do. Not that GM cares, but I will never buy their product ever again, just for the mere fact of how they treat their customers when they need them the most.
Sincerely,
Another victim.
2015 Silverado Trans went at 109 thousand,dealer replaced with Napa rebuild now shutters,they flushed 600 miles later still shuttering. Taking back for Napa warranty again.
Can someone PLEASE tell me how to join this law suit, it cause an accident and $15000 in damages.
How do we get in on the lawsuit
For compensation if won? In the process of rebuilding my transmission with less than 80k miles on my 2016 silverado
I have a new 2021 Silverado RST with the 8 speed transmission and it does all these items.
I have a 21 Silverado RST also and had the valve body replaced. Went from a violent jerk to a occasional soft jerk but only seems to happen when I’m towing.
I just bought a 2021 silverado with less than 2500km. Brought into dealer and they said it’s’normal”. I advised the safety issue and the dealer just give me a phone # for GM. Until GM owns up to the issue, the dealer won’t do anything.
Yes you have to call GM and get a case number Keep taking your truck back to the dealership. I got super lucky and it did a violent jerk while test driving it with the dealership head mechanic. I knew at that moment I had them and it wound up being the valve body. I just bought a range DFM disable also that may help
Many of these comments are from January of 2021. Has any progress been made with this lawsuit on the transmissions? My truck a 2019 GMC with 27,700 miles is in the shop for the 5th time with the same transmission problem. I want my truck fixed or get my money back!!! By the way, I just paid it off early and just got my title in the mail.
My 2018 GMC Canyon SLT (V6 – 8 speed transmission) started to vibrate and shutter under light acceleration after just a few thousand miles – about 2,700. The dealer’s service department told me it was a tire or shock issue, and not to worry. I reported the problem again, because the issue was worse. I was told to bring the truck in for a review. A TSB was noted that could be related to my issue. The Torque Converter was changed as well as the fluid, and a software update installed. The issue was cured as of Nov. 2018. The issue returned in Nov. 2021 at 13,900 miles. I reported the issue and was told another TSB might resolve the issue. The fluid was changed again. This was covered by the 5-Year or 60,000 mile Power Train Warranty. The issue again was resolved, but for how long? My warranties are now almost gone. I hope the issue is finally resolved. However, with low miles and high demand for used trucks, a trade might be in my future.
We are putting a second transmission less than a years time can’t afford theses repairs and payments never have I had such a horrible experience before and there customer service was once great with respect and understanding now that no longer exist either not what we ever expected
Are you listening GM ? I for one will never purchase another GM vehicle if THIS is how you treat your customers.
Gm has head engineers to oversee the designs on anything they make.. then they go through tests to validate the product.. you need to ask for them test sheets for that transmission before it went into production. That will tell alot about the transmission. And the corporation has to sign off on the product before it goes into production.. so design flaw or not engineers and corporate signed off stating that that product was safe and reliable. All in all someone designed and corporation approved it. Its the corporations fault for passing a defected design and allowing it to go I to production
surely this will effect emissions testing when the pos Barra Transmission slips and shudders. The defect is in the paid off legal system. GM has alot of money to spread around in Detoit.
