Buick Enclave Transmission Questions

    Hi trollo,

    We're sorry to hear that your vehicle is being repaired for the transmission. The good thing is that this will be covered under your warranty and you won't have to come out of pocket. We hope everything goes smoothly with your repair. Please keep us updated on this process.

    I just read your thread on your problems with Enclave. We, too, have had the same problems when using cruise control in the mountains. We took it into the dealership and they are "unable to replicate it" and even asked my husband if he accidentally manually shifted which he did not. My husband believes this is extremely dangerous as the only way to get the car down from 5000 rpms to 2000 was to put car in neutral as the pressing the breaks didnt help. I have also noticed that the car's rpms jerk when the car is traveling between 45-50 mph even though the gas is being pressed or released. What did your dealer say? We are scared to take the car into the mountains again until this is fixed.

    I have a 2008 Buick Enclave that I purchased in September of 2008, it has roughly 50,500 miles on it. This past weekend when driving out of town, the car began having issues switching gears at high speeds. It was happening more frequently the closer we got to our destination. When we arrived at our hotel my husband, suspecting a transmission issue, checked the transmission fluid. There was plenty of fluid, clearly a bright pink in color; however, there were metallic shavings in it.

    We had to have the car towed to the closest dealership because after stopping the transmission would no longer go into reverse and we couldn’t get out of the parking spot. The dealership told us when they looked up our car in the GM database, it was out of warranty! That our car had gone into service in June of 2008!

    We got a rental car and said we’d fax them our paperwork denoting the mileage at purchase and the purchase date. We did this and the dealership contacted GM on our behalf.
    GM’s response? That we purchased a USED car and that they did not need to honor our purchase date!

    The dealership when we purchased the vehicle, told us that the warranty would be good through 40,438 (438 is the number of miles on the car when we purchased it) or 100,438 (for the power train warranty) or 60 months, whichever comes first. So at this point we have reached neither date nor mileage according to our purchase documents and the agreements we signed. Does an agreement that GM has with the dealership from June supersede our agreement with the Dealership? Do we need to have our warranty repair work done at the dealership we purchased it from?

    Either way this feels like a very shady way to get out of fixing something that should last for 100,000 miles or more. Very shady GM, very shady!

    I'd be more upset with your dealer, than GM..

    They sold you a car that had already been reported as sold, and the warranty clock was ticking, yet never disclosed that to you.

    Seems like a small thing, until now... I'd suggest to them in a kindly way, that they've perpetrated a fraud on you, and you expect them to stand up and make it right.

    Hello rjconsumer,

    I'm very sorry that you've experienced this, and it seems like there's been a lack of communication throughout this process. I'd love the opportunity to take a second look at your case and clarify any additional details. If you are interested can you please email me your name, VIN, contact info, and dealership? I look forward to hearing from you.

    While researching our own engine shifting problem, I've come across many different scenarios all with the same outcome of engines not shifting out of proper gears. If the dealers cannot replicate it because they can't take the car on long road trips or down winding hills then the only recourse is for all of us to file a complaint with the NHTSA or Personally, I feel like this is an extremely dangerous situation as even hitting the brakes on our car failed to take the engine out of high rpm. The only thing that worked was shifting to neutral. After reading your story of the engine not going into reverse what happens if neutral doesn't work either? I'd hate to find out going 75 mph.
  • Probably sound like a broken record, but on my way home from work Thursday and on my way out of town for the birth of my grandson, my 2008 Enclave with just under 73K miles, RPM's started revving up super high when it needed to switch gears, then would finally slam into gear jerking the whole car. I was on a major interstate and terrified to say the least. I had complained to my dealer twice before that there was something wrong with the car when it shifts, but was pretty much blow-off both times so now here i am with a very expensive car sitting in my driveway waiting to be towed to the same dealer that blew me off when it was under on earth can GM ignore so many complaints and issues with this car???If I have to replace the transmission, I really don't know where the money will come from...
  • I echo your comments. Same scenario here: 105,000 miles on a 2008 Enclave purchased new off the showroom floor; problems have included leaking sunroof (multiple service visits), steering issues where main front-end support assembly mounting bolts loosened and needed realignment and re-torqueing (with no valid explanation as to why this happened- this also required multiple service visits), and today the transmission fails! Now waiting on a "GM Certified" transmission to arrive at dealership.

    When I inquired about the "GM Certified" vs. "New in Crate" transmission, I was told that the only option is a remanufactured transmission (GM Certified) and is warranted for 36months/100,000miles; a "New" transmission is not available but if it was available, it would only carry a warranty of 12 months/10,000 mile warranty because it would be classified as a new part. And, it would cost more than the certified unit. Does this make sense?

    It is quite obvious that GM has a serious problem and long-term customers like me (8 new GM vehicles in the past 25 years) are very dissatisfied and for good reason. As a loyal GM customer, this is the proverbial end-of-the-road for me and GM.

  • I purchased my 2008 Enclave new, and I love it, but I do NOT like the dealerships. They are dishonest to say the least.
    I've had the same problem with the RPMs shooting up while stopped at a light, but dealership says they can't duplicate, so it's my problem.
    Had two Schrader valves replaced for my AC, and they charged me $500! Should not have cost more than $200.
    Now my rack and pinion steering is making noises AGAIN. It's been replaced twice (so they say), but this time they want $1200 from me because my extended warranty had expired 10 days before - outrageous! There's more, but I don't want to belabor this message.
    Now that I'm reading these blogs, I am absolutely ready to get rid of this vehicle - love the vehicle, but I will NEVER buy another GM product.

    2008 Buick Enclave - 71K miles

    I too can relate to the Enclave owners with transmission issues. Monday the transmission seemed to be slipping, skipping then jerking into gear. I (a woman) brought it to the dealer 2 days later, I explained the transmission didn't seem to be working right. After inspection they told me it was an engine plate cover leaking oil issue and the "transmission was operating as designed". This didn't seem right, so brought to our local mechanic and was told it was a transmission issue. My husband brought it back to the Buick dealer and after again inspecting it, they confirmed this is likely a wave plate issue, a known defective part with a TSB (technical service bulletin) by Buick. A significant cost to fix.

    Yesterday (4 days since we first noticed the problem) the transmission completely stopped working and the car will no longer drive.

    The kicker is that we bought this from a GM dealer as a certified pre-owned vehicle in 2011. The car took original ownership July 30 2008 and therefore is out of warranty by 2-1/2 months. But it's near 30K miles under the warranty.

    We've kept up with all work, most of which has been done through an authorized Buick dealer.

    We feel this should be fully covered by GM. Before jumping to conclusions and posting our negative experience with GM, I wanted to give them the chance to handle the situation properly. Who do I contact for help with this?
  • We've had our Enclave for a little over a year and it seems like every four months it needs a serious repair. First was a water pump. Next, brake booster and master cylinder. Today it got to take a ride on the back of a flatbed to the dealer. It needs a new transmission, steering gear and possible a power steering pump. I'm hoping all of this is covered under power train warranty or the extended warranty from Carmax. It's the first car that my wife has "loved", but I'm afraid it's future is not long with our family.

    We've been in touch with Buick corporate, talked with April. Issue has been escalated to the District Specialist and we should hear more on Monday/Tuesday. Will send additional update at that time.

    I feel your pain. Had the water pump done, brake booster and master cylinder all this year. Now more issues. BUT, we got a letter a few weeks ago from GM about water pump. Sent in receipt for repair and are expecting a refund (we did not get repaired at GM). So if you haven't been reimbursed for that, look into it.
  • I have just read these post, and am scared to death!! My transmission light just came on, and I am about to have it checked. My question is, how long is the powertrain warranty? I bought my 2008 car with 35K miles on it (now has 86,000), and my warranty that I purchased just went out. I assume the transmission is covered under powertrain, but how long is that good for?
  • I beyond mad and upset, got this truck 2008 model back in May 2012, I had to get rotors replace days after purchase. Then later on replace battery. Replaced tires shortly after buying and lights twice. Now at 48,xxx my transmission needs replaced. And they are confirming if it's covered under my extended warranty. I put a nice hefty down payment on this truck and I just feel like I threw my money down the drain. Per hearsay I am hearing even after transmission replacement I will have ongoing problems. After reading up on this car I wish I would of did my homework. Nice look but a piece of trash and Buick won't own up to it
  • I have a similar problem with my enclave. When I start accelerating it will not shift out of low gear. I took it to a transmission shop and they said my transmission is fine but it could be my battery. I have not replaced my battery yet but I if I pull over and turn off my vehicle for about 10 seconds then it clears up. I have found out that the enclave's are power hogs and need really good batteries to function properly.
  • Second steering wheel column/rack and pinion replaced within 2 years. I guess the "Out of a job yet? keep buying foreign" bumperstickers can be changed to "still buying domestic? at least your mechanic will have a job for life"

  • Has GM done anything to recognize the piece of junk transmission that they put in the 08 Buick Enclave. It seems like the same story is told by every enclave owner. I have an 08 enclave with 61 k miles, never towed anything, blown transmission. I opened a case with GM customer care almost a month ago. The case was assigned to a supervisor named Lucenda. After talking to her a couple times, she promised to call me back in an hour with a resolution. That was a week ago. I have left 10-12 messages. I have talked to three others that promised to have her or someone call. Nobody will call back. I have a hard time believing that GM customer care has gone down hill this far. Does anyone have any advice on how i could or should proceed. It is enough that GM put a substandard transmission is a very expensive car, it is another to hide from their mistake.

  • 2008 Enclave - broken wave plate in the transmission. 61 k miles. GM customer care keeps repeating that it is out of warranty. I know that it is on years. i can calculate the age of the vehicle. It is not rocket science. My request is that GM honor their mileage warranty because they know they produced a sub-par transmission. The age of a vehicle does not wear it out, miles and use wear out transmissions. I have owned a dozen GM vehicles, never once have i blown a transmission. i bought this enclave brand new as i do most my cars, and expect more from GM. What have others had to pay to fix their transmissions?

  • 2008 Buick Enclave, 95000 miles. I brought it to my local mechanic in May because of shifting problems. He brought it to a very experienced transmission repair company. They spent 4 weeks trying to fix the problem because they did not want to give it back to me until it was running perfectly. In the meantime, I contacted GM Corporate and they told me that my car MUST be at a GM dealership in order for them to assess the situation. When I told the transmission company this they said that the GM dealership will tell you to put a GM transmission in it, collect 5000.00 and say SEEYA! And guess what, the car is at a GM dealer now and that is exactly what they want to do.... almost 10 weeks later.

    So, the transmission company is not charging for the work they did... Quirk Chevy in Braintree, MA will not release my car until I pay $1200.00 for work they have done and the car is not fixed and they want to put a GM Transmission in the car for 3500.00!

    What happens when the car still doesn't work after the transmission is put in? I'm stuck with a 400.00 monthly payment for a car I can't drive and $4700.00 poorer!!!

    The new transmission should be under full warranty if it's coming from GM. Be sure you get all that in writing. If the independent transmission shop can't fix it, and you don't want to pay the dealer, you're in a bit of a bind here. Has anyone given you any info as to what the problem is? Broken wave plate probably? It's a common problem on Enclaves of that year.
