I would hope the dealer at least reset the computer so it can "relearn." Worth a shot anyway. They should also check the wiring and sensors to the transmission. With everything computerized these days a break in the wire can cause major issues. Also, GM needs to pay it's techs more for warranty work so they do a proper job of tracking down the issues.

I purchased a 2018 enclave two months ago with 40,000 miles on it. Almost immediately I felt the shuddering from gears shifting because I just went through the same experience with my 2010 Yukon and that’s why I traded it in the first place. I took it to the dealership today and 3 1/2 hours later they told me they reprogrammed the ECM and changed the transmission fluid. I have to drive it two hundred miles to see if the problem still persists, but I could tell as soon as I drove it off the lot that the problem is still there. On a different subject, but sort of ties into the issue, I can’t stand the start stop feature on this vehicle. And even worse, you cannot disable it without purchasing an item to plug into the ODB II receptacle. I called the company to see which one I should buy because there is also an item to disable the AFM (active fuel management system). On their website, it says if you disable the AFM the shutter may stop. So, besides thinking the problem is a torque converter, it could be the AFM. The company is range technology, and they don’t have an item that disables both the AFM and the start/stop feature at the same time. It’s either one or the other. Here’s the kicker, the thing cost $200. The salesman that sold me the car, luckily for him, was not in there today.

My 2018 with 66k on it died to day the transmission just quit at a stop light. At dealer now .

 

[Alvenir]

That's unusual, but at least it's under warrantee.

 

[gig229]

All of these transmission issues doesn't bode well for long term reliability unfortunately.

2018 Premium. Shuddering began around 15k, usually if the nose was down like on a steep driveway. Was very intermittent. Pandemic hit and we didn't drive it that much due to the kids being home doing online schooling. But anytime it was driven it shuddered on and off. In low gears. I finally got my husband to take time off work to take it in. The local dealership had it 3 DAYS and said there's no problem, but it was time for its transmission flush. at 42k miles? Fine, but hey! It's going to cost me $300. (Btw I HATE this dealership.) Picked up the Enclave and it seemed like it was better. WOO!! Then...2 days later it bucked and shuddered. They won't do anything about it."Its a quirk". Now we're at 49,600K miles and I'm waiting on 2022's in the Enclave and a few other brands to be released. My issue is it shudders and bucks on cold starts or if it's been off for over 2 hours at the least. It doesn't do it usually once it's going and past the low gears. but occasionally there's a BANG and it shudders.

I'm really NOT looking forward to a 3rd Enclave. They've gotten WORSE as time goes on. But we cannot find a 7 passenger that has the space the Enclave has. We don't like Toyota's or Honda's, as their tech seems to be behind.

I hate my local dealership and do anything I can to avoid them, but they're the closest and none of the Chevy dealerships want to touch it.

 

[gig229]

You don't like Toyotas or Hondas? Like all the latest "tech?" Then get used to these types of problems. Sorry but I've LIVED the many, many problems with my 2009 Buick Enclave I bought new. I spent well over $8,000 on repairs, and I have only 90,500 miles. I can't believe after all the transmission issues with the first generation Enclave, they wouldn't put some money into the new Enclave transmission to ensure it lasts at least to 200,000 miles with no issues providing regular maintenance is done. If Toyota can do it, so can GM, but their MBA Cost Accountants won't let them.

So GM products are lease only, provided you're okay with all the time you'll spend at the dealership. But hey at least you'll get to know your service advisor really well.

Nope. Hate the look of Toyota and Honda. We also don't buy into their hype of long life. We've had a few and various family members and friends have or recently had them and they left for other brands. Faulty electrical, transmission, paint issues, window motor issues, bad customer service, etc are the main gripes. We also have 5 kids and unless we want a minivan, none of their SUVs were big enough or comfortable enough, or they drove bad for us. We 100% understand more frills, more problems. We typically only keep the 7 passenger the length of the warranty. Which mine was up at 50k, aka 2 weeks ago. We were gung ho for the refresh, then the pandemic happened and we waited. The longer we have waited the more disenchanted we've become with the Enclave. I'd likely be more excited if I didn't have a trash dealership. 3 days for them to tell me the transmission just needed a flush. They also said our brakes were bad, despite them being new and when we checked them, they were perfectly fine. There's way more to my interactions with them, but we bought 1 vehicle there and that was it. But unfortunately, if the vehicle has a problem I'm stuck having it towed there. If it has something wrong with it and it's driveable, I can either go there or an hour out of my way to the next closest.

I LOVE the style of the Buick. I LOVED my '15 also. But face it, most cars are 'disposable' anymore. Not just GM.

 

[KDeiss]

Purchased new 2020 Essence FWD Oct 2019 around Jan 2022 started the tranny shutter as described here. Dealer changed fluid shutter gone I hope it stays that way….

 

[kolczdm]

Yes, I have a 2019 Enclave Premium and just had the Trans Fluid changed at 28K as dealer recommended. Really did not solve the dead zone issue. By dead zone I mean if you are driving thru a neighborhood like 20-30 then coast alittle then accelerate it seems to have a dead zone before the trans catches again.
What i would like to do is reset the ECM & TCM back to factory settings and see if that works. Would anyone on the forum know if this is something i can do myself? I have watched some youtubes but not sure about those procedures. Thanks for any assistance.

 

[Element1]

My 2018 has 24K on it and I did take it in for rough shift back at 7K. They said there was a change in the fluid type to be used and no problems since.

What type of tranny fluid should be in 2018? Ours has 19945 miles on it (10/30/22) and is rough. No one at dealership has ever said anything about incorrect fluid.

 

[CAC 18 Avenir owner]

Has other people had problems with the 2018 or 2019 enclave transmissions. My tranny is currently being rebuilt. It only had 7000 miles on it.

At 80K our Avenir transmission is slipping. We are now investigating the problem. This makes me sick as every Toyota I ever owned never experienced any problems through 209K. :-(

 

[5Demons]

I will say, that our '22 Avenir with 16k miles already...rides AMAZING and no skipping. Very little gear shifting is noticable and even then you have to be paying attention to it. So Buick definitely decided to fix the big issue. My father in law even traded his '21 Avenir in for a '23 because he drove ours and literally yelled YES! After he did. It's by far my fave out of the 3 we've had.

I have also had issues. 24k mikes on mine and had to have torque converter replaced. Solved the issue temporarily, now it’s slowly having problems again. Also have had entire fuel system replaced. You should contact GM, I’m seeing that a lot of people are having issues with these vehicles.

What year is your car and how much was the torque converter replacement? I just got a 2019 that shudders and am waiting to hear back from warranty…. Advice?

Did you ever find a solution? Warranty is offering $4k for torque replacement, but I’m scared it’ll come back and I’ll have to pay for a full transmission. What did you end up doing?

 

[Caleb17]

Had mine for 4 days. Purchased as a “demo/wife driven” at 3000 miles. It feels like it is jerking or shuddering between 17-30 Mph. told them the next day. We are being told it has to,”sync” with the driver. I’m not happy. A $40,000 vehicle should NOT be doing that

Did you ever find a solution? I’m facing a similar dilemma.

 

[Caleb17]

I found your message more than interesting. I have owned a 2019 Avenir since mid December 2018 and find it to be a beautiful car except for one very important aspect. For the record, this is my second Enclave (2012) and maybe tenth Buick. I always loved the smooth, powerful performance of a Buick. The 2019 is probably the best car I have ever owned on the road but just miserable around town. I find the 9-speed shifts much too often (6 speeds was just fine) it "chuggles" in the middle gears (3 or 4 thru about 6th). This is the dealer's and GM's term for the shuddering I feel when the tranny shifts. They claim it is skipping gears if you don't put your foot in the throttle. I don't like to overdrive, especially around town, so I find the chuggling to be very prevalent. Sadly, they say there is nothing that can be done.
Which brings me to your note. Please describe what brought you to getting a new transmission. My 2019 only has 6000 miles at this point.

Did you ever solve the chuggle? Just got a 2019 with 93k miles and warranty wants to replace the torque converter.

[Caleb17]

I have a 2019 Buick Enclave, just 4000 miles and in the shop now for 10-days with a transmission issue.

What turned out to be the solution? I’m also having transmission issues.

For how long did the torque converter solve the issue (in terms of time/miles driven)? I’m also having transmission issues.
