GM Recall Issued For Missing Transmission Bolts On Chevy, GMC, Buick, Cadillac Models

General Motors has issued a safety recall for a variety of Chevy, GMC, Buick, and Cadillac models due to missing transmission accumulator bolts. The GM recall includes vehicles both in the U.S. and those sold internationally as well.

The problem: General Motors has identified a defect on certain Chevy, GMC, Buick, and Cadillac models wherein the start-stop transmission accumulator may have bolts missing. The missing bolts can be found on six- and nine-speed front-wheel drive transmissions.

The hazards: missing bolts on the start-stop accumulator endcap could possibly result in a transmission oil leak. If the leak is not fixed, the problem may progress to a loss of propulsion, which could ultimately lead to an increased crash risk. What’s more, leaking transmission oil in the presence of an ignition source could increase the risk of a fire as well.

The fix: regarding this GM recall, dealers are currently instructed to inspect the start-stop transmission accumulator on affected vehicles and replace any bolts that may be missing

Affected vehicles:

Chevrolet

Buick

GMC

Cadillac

  • 2019 – 2020 Cadillac XT4
  • 2020 Cadillac XT6

Number of affected vehicles: it is not yet known how many vehicles are affected by this GM recall.

Owners should: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer.

  1. Is it just me or all most “domestic brand” recalls due to Labor fails and most “foreign brand” recalls due to supplier issues

      1. Glad to see the issue has been caught and a no-customer-charge remedial action is in place.
        However, as an analytical investigative engineer type, this is very peculiar on so many different levels. IMO the worst being it shakes customer confidence to the core. Vehicles aren’t inexpensive today,,,, where is QUALITY being job numer one ??
        SO, what is the ROOT CAUSE of this issue???
        Did the bolts become loose and fall out with use,,, Were they initially supposed to be assembled with the extra bolts,,, or as a cost savings measure were they initially omitted thinking not necessary then field use showed otherwise? Or is it a human influenced assembly issue? Interesting its inferred that a hole and perhaps threads already exist in the castings! So that would suggest they were initially designed for the extra bolts!
        So…. is this an initial engineering/design issue, assy change order issue, sloppy workmanship issue, untrained worker issue, sabotage issue?? I could rationalize an occassional missing bolt that should be caught by QC, but enough cases to warrant a recall?? Something really seems amiss behind the scenes on this one!
        Makes me think twice about spending 70k on a new diesel truck! Let us not forget what happened in the 80s concerning QUALITY with domestic-made automobiles!!

    I’m glad they found the missing bolts.😉

      Exactly. That’s what happens when GM piles 61 seconds of work on a person in a minute.
      People can only do so much.
      For those of you that have recently been on the assembly line, you will understand.
      Those who have never worked will give this a thumbs down.

  6. My 2012 traverse has loss of propulsion, bucking, and transmission issues. I’ve contacted chevy and the NTSB numerous times and got no answer. Chevy cars suck. I have 5,000 left on my loan still and my car is running like shit. Ill never buy another chevy as long as I live .

  7. yeah I’m an older person and I expect a lot of general motors because I work for them when they used to be really on the ball yeah they had recalls then but this is stupid in this time and age missing bolts, I wonder if that’s why my 20/20 terrain when I’m stopped at a light and the engine shuts off it starts before I take my foot off the brake pedal and the car jerks, very disappointed with the car spent almost $42,000 on a not fully loaded GMC Denali terrain.

    1. Auto stop start is just harsh on most cars, you probably don’t have missing bolts causing it. I’ve had A.S.S. on last 4 cars, and it was pretty jarring on most of them when it restarted when you were stopped waiting for a light for example. It’s barely noticeable on my 2021 Jeep Wrangler though even without eTorque.

  8. What is a start-stop transmission accumulator?
    I understand start stop technology. ..
    Is it some sort of oil pump while the engine is stopped?

    Reply
    1. Accumulator holds pressure when car is off,so transmission is ready when car starts.

  9. They probably found the error when the bean character said good job in lowering the cost for your bolts

  11. What ever happened to doing ones job to ones fullest potential. Obviously someone did not install the bolts or there is a serious problem if bolts just fall out driving down the road. C’mon guys, these vehicles are no longer low cost to buy. Do the job you’re paid to do.

    Who really messed up not including the bolts ?

    Does anybody know ?
    There never is any news about investigating why these things happen.

  14. Seems like more recalls than usual on here lately.

  15. The Buick Envision wasn’t affected is that because its assembled in China?

  16. There’s NO excuse whatsoever for this mistake, as it includes different assembly facilities and many different models, so much for QUALITY CONTROL!!! In the old days, it was said, don’t buy a vehicle built on Friday or Monday, as mistakes usually happen at the end or beginning of the work week. But now it seems to affect most vehicles that were manufactured during the PANDEMIC!!! Look at all of GM’s mistakes coming out of Bowling Green, Kentucky, GM’s PREMIER Corvette assembly plant, it’s unheard of at this time.

  17. I am real worried about failures on my $75K C8 Corvette. Gm seems to be in the let it ride till its sold then fix it if we get caught repair business. Not a lot of faith in them
    but the stock keeps rising so share holders love Barret even though she dumped a ton
    of her stock recently!! I like the look and performance so here’s my ante deal me in.

    Just Saying!

    SO, what is the ROOT CAUSE of this issue??? (I Realize most customers don’t care… just fix it!!)
    Did the bolts become loose and fall out with use,,, seems like the most likely scenario… but WHY? How will the replacement bolts be prevented from doing the same? Therefore seems to suggest an engineering issue as a root cause.

    OR more sinister:

    Were they initially supposed to be assembled with the extra bolts,,, and as a cost savings measure were they initially omitted thinking not necessary then field use showed otherwise? Or is it a human-influenced assembly issue? Interesting its inferred that a hole and perhaps threads already exist in the castings! So that would suggest they were initially designed for the extra bolts!

  19. There IS a customer charge. Going to the dealer for service is a pain . If it is a simple recall you will waste most if not all of your day. Most people don’t have a dealer down the street. They should come and get the vehicle and bring it back when done or fix it on site depending on the repair. That’s what Lexus does.

    Reply
    1. Daniel,,, YES,,, thank you in pointing out that while there is no direct charge, there definitely is a ‘cost’ to the customer on many different levels!
      Did not mean to minimize that in my post! Thanks, Alex

  20. OK, you can’t blame this on a vender issue ! This is a quality control issue , once again GM is lacking behind the other vehicle manufactures in this aspect. They are going to HAVE to get this right !!

  21. GM difference had plenty of problems, I just bought a 2020 Chevy Silverado. When I fought out the problem they are having with the Silverados I would have never bought one. I have a 2013 srx Cadillac needs new headlights GM is a joke. ( Never again)

    1. The SRX headlamp assemblies are total junk. If you are handy you can buy knockoffs from rockauto.com for around $130 each. That is way cheaper than the cadillac dealer wants.

  22. I remember the days in the 60’s when they built cars with parts missing. They would sell the cars to people and then expect them to go back to the dealer to get stuff fixed. Had a 68 Plymouth Satellite with no manifold gaskets. It leaked oil in front of the engine and behind. The dealer refused to fix it on warranty. History repeating itself I guess.

  28. Typical GM junk. Never put good money into an inferior product from GM! Better to put it as a downpayment on a Toyota or Honda and make payments on the difference in cost between the GM price new to the Toyota new price. You will be happier in the long run!

  30. My husband automates all brandd of vehicles in Canada. GM has the best QC, parts, processes in the business. Acura, Honda, Ford and Chrysler use less welds making their vehicles death traps in an accident. Kia, Hyundai are rust buckets, cheap windshields that break almost instantly and they all fight you on warranty fixes. My ’17 Cadillac XT5 V6 is strong, comfortable, luxurious, sips gas and reliable. When these companies buy parts from Mexico, China even Japan, they are always the problem during recalls. Every brand has a warranty for a reason…best experience comes when they don’t argue or blame you for the breakdown! Recalls are good…they are protecting you in advance of a problem instead of hiding it. GM is not like the 60’s buddy. Educate yourself…you sound ridiculous.

  31. 1996 is about the year GM stopped making quality vehicles. Their offerings now may look great but under the skin they are just thrown together. Even the high-end flagship, the new mid-engine Corvette, has defective alloy wheels and horrible build quality with missing screws in the vent work and sloppy stitching in the way the interior is put together.

  32. I love when people say GM is junk, yes it’s getting to be tiring with the amount of recalls but they only have that many because if they find even a small issue – they fix it. They dont just let it go like Hyundai did with the velosters and the engine recalls they recently had. I’ve worked at a GM Dealer for a few years now. Out of the vehicles we’ve called in for – this recall of the Transmission Accumulator Bolts ‘Possibly’ Missing, no vehicle has been needed to be held for repair. It’s just a safety precaution because they had a few that have come back because the trans is leaking.

  34. I would not buy no brands if GM. They do not value their customers nor take responsibility for the problem with clear coat. There quality control is a mess. Mistake after mistake. I am fighting this problem now. View photos on Capital Buick GMC, Smyrna, GA.

    1. I agree.
      I have to laugh when Mary Barra says GM ‘earns’ Customers for Life. That statement shows how far out of touch with reality, GM leadersheep has become.
      When GM screws over a customer they create an ‘Ex customer for life’.

  35. After hearing all these issues I am certainly glad I decided not to buy a new GM this past Fall. The only reason I didn’t get one is because when I told the salesman I was going to wait and get a 2021 instead, he told me they weren’t making any 2021s, so I should buy the 2020. If he can’t tell the truth about that I’d be afraid that their word is useless.

  36. We were a GM family once upon a time, back in the 60’s thru mid ’70’s. Everything they have built since then is absolute junk! We’ve been exclusively Toyota/ Lexus for over 20 years. They ALL get 250- 350K miles easy with just basic maintenance.

    It’s a no brainier, and worth the higher initial investment!
