Details: The amount of reimbursement for which you are eligible depends on (i) when the Covered Repair was performed and (ii) the amount you actually paid, as described below:


    1. For a Covered Repair made within five years after initial vehicle delivery:
      You are eligible to be reimbursed the documented amount you paid out-of-pocket up to $400, if you were not previously fully reimbursed.

      However, if you can document that the Covered Repair required you to pay over $1,500 to address an internal coolant leak, your reimbursement level may be different. If so, you can elect to request reimbursement of 40% of the amount you paid out-of-pocket up to $800, if you were not previously fully reimbursed.

      (An internal coolant leak means that coolant leaked from one vehicle component into another component. Whereas an external coolant leak means that coolant leaked from inside a vehicle component to the exterior of the vehicle.)


    1. For a Covered Repair made in the sixth year after initial vehicle delivery:
      You are eligible to be reimbursed the documented amount you paid out-of-pocket up to $100, if you were not previously fully reimbursed.


  1. For a Covered Repair made in the seventh year after initial vehicle delivery:
    You are eligible to be reimbursed the documented amount you paid out-of-pocket up to $50, if you were not previously fully reimbursed.

If you paid for more than one Covered Repair (whether on the same vehicle or on different vehicles included in the proposed settlement), you may make a separate claim for each repair.

GM vehicles listed below are covered. Please note, below is for everyone BUT those in Missouri. If you’re in Missouri, please Go Here for more details.

There are three groups of vehicles that are covered by the settlement: Group A Vehicles, Group B Vehicles, and Group C Vehicles. Each group of vehicles is listed below, followed by the Covered Repairs for which cash reimbursement is available under the proposed settlement.

Note: Some of these vehicles may have been offered for sale with an engine other than a 3.1-liter or 3.4 -liter V6 engine. Any of the above models sold with an engine other than a 3.1-liter or 3.4 -liter V6 engine are not included and are not eligible to make a claim.

TCA Staff Tidbit: So, straight to the point. . . Did you encounter ANY problems related to your radiator or cooling system in one of the GM cars covered in this lawsuit? If so, make sure to submit your claim. You probably won’t get all of the money you put into the car to repair it, but you should get at least SOME of it back. At least enough for a nice dinner out for two! If you lost the receipts, you’re out of luck, but hopefully your garage or dealer will reprint them for you. That’s it! A long post, sorry about that, but there’s a lot of material to cover.

    Nothing but junk GM builds I got nothing after turning in reciepts . GM re-invented? Ha! This company is out of business it may take a few years but after the bankruptcy is temporarily over they will go bust for good/ There is nobody in their right mind that has gone through the problems of GM products that would buy another!

    My 2001 S10 was not included in this lawsuit. At 77000 miles my radiator hose busted. Had to replace. New DexCool was added. 30000 miles later the radiator busted. Had to replace. New DexCool added. Now, 20000 miles later, I am replacing the water pump. Orange sludge is everywhere. No DexCool will be used this time. I WILL NEVER, EVER BUY ANOTHER GM PRODUCT. Furthermore, I will let everyone I know they need to STAY AWAY from these sorry GM vehicles.

    I am writing this letter in regards to my vehicle . I have a chev venture that I purchased in 2004 , at that time I thought that it was a good deal . I had problems also with the intake gasket which cost me over a $1000 to repair , I was told by an employee that there was a class action suit against the company for this defect . I have relatives that retired from this company so we have always purchase GM cars . I can believe that this matter is handled so unprofessionally , I submitted necessary documents to be reinburst for the cost never even got a letter stating what would be done , I am so disappointed with this situation .

    I own five of the subject vehicles, two 3.1’s, two 3.8’s and one 5.7 truck. I first discovered a coolant leak, replaced the faulty intake gaskets, thoroughly flushed and changed all five vehicles over to good old “green antifreeze! No more problems, usually flush and fill every two years or 30,000 miles. I have well over 160,000 on two the the vehicles, the others are over 120,000 without any issues. The GM pink stuff is called “Dex-Cruel” for a reason!

    Never heard about this class action but I’m here to tell you that my ’96 Chevy Corsica 3.1 6 cylinder w/ 108k has the same problem as everyone elses… coolant leak do to intake manifold. Had the car 11 years and only real expense was 2 alternators. Now the biggie finally hit and the car is pretty much shot. The leak caused internal damage. I was hoping to drive it a few more years but I guess that won’t happen. I now intend to buy foreign.

    First it was the water pump and and then it was the engine which now has cost me over $3000.00 out of pocket for my 3.8/six cylinder 1999 Buick LeSabre.
    I had filed for my claim with valid documents well in advance of the closing date for filing and have yet to receive a single penny…

    I believe the law firm is just as crooked as GM is…

    I own a 1996 Buick Skylark and a 1997 Chevy Malibu. I caught the the leak on the malibu after my oil was contaminated with anti freeze. The top of the engine is off the car for repairs. On the Buick I replaced the intake at 50,000 miles and at 103,000 miles the leak caused the camshaft to break. Now what am I supposed to do? Both are the 3.1 engines. GM, please send a check to replace both engines.

    It’s May of 2011 and I just learned about this GM mess. Two weeks ago, a dealer replaced warped cylinder head gaskets on my 2002 Venture due to the coolant problem. The van only has 56,000 miles on it and I just had the coolant replaced last Fall – obviously, it was too late, the damage had already been done. Paid over $1,000 for the fix and am about to return the vehicle to the dealer because the problem has not been solved – still having the same symptoms as when I brought it in. Totally disgusted, with no apparent legal recourse. I don’t see where any additional lawsuit has been filed about this since the one in California was closed in 2009. If anyone knows of one that’s still open, please post a comment!

    I had my intake manifold replaced in 2009 due to leakage. I knew nothing of the problems until last week (Aug 2011) when a mechanic told me of the problems with GM vehicles. I have my receipt for parts and labor and would like something to be done about it. I also want to know if there is a case still open to get involved. Irritating!

    I filed all the paperwork that was asked for to file a claim for repairs on 2 GM vehicles (1997 GMC Jimmy & 1996 Camaro)
    It did not include additional repairs that I had to have done because these were not included in the list of years and models. I inquired about the litigation afterwards and was informed that GM was in bankruptcy, so everything was put on hold at that time. I have still not heard anything about my claims. Needless to say I will NEVER buy another GM

    I love this stuff (outside of having a dead Monte in the driveway).

    If I understand this correctly…

    The lawyers get approximately 75% of the “settlement” money, which amounts to (approx) $18 MILLION.

    The “class” gets approximately 25% of the settlement money, which amounts to (approx) $6 MILLION, which is spread among thousands of people.

    No one was “properly” notified about this class action suit, myself included. You know, they could have easily gotten this information via registered vehicles, which is the way that I’m guessing “recalls” are handled.

    And NOW noone can take legal action against GM individually because these folks have chosen to do so for us (without telling us and without giving us OUR day in court).

    Yep…sounds pretty corrupt to me.

  • Anonymous September 23, 2011

    I was just told my head gasket is shot and it will be around $2,000 to replace. The garage said they have replaced coutless head gaskets on 3.4L GM vehicles. I knew I had an minor external leak but was never informed that it would get worse and could potentially wreck my motor. 5 minutes of on-line research points to problems with Dex Cool coolant and erosion of cheap head gaskets. GM should own up to their use of crappy parts and reimburse everyone that has had or will have problems down the ‘road’. I doubt that will happen as there has been a class action law suit negotiated and closed in both Canada and the US. This does not help those of us experiencing problems now. We as consumers need to think about our future car purchases (all purchases really). I am of the ‘buy-local’ camp but will stick to local veggies and cheese, and look for a reputable foreign manufacturer for my next vehicle.

    Glad to see the lawsuit was resolved, too bad I didn’t hear about it though to get my ~$200 or back when I had the repair done back in 2005 (on an 02 Grand Prix).

    For those still running this coolant I believe I have tracked down the reason for dexcool’s failure. When you open a new bottle of dexcool the pH is roughly 8.5. I just measured the pH of my dexcool about 5 years since the repair replacement, the pH is about ~7.0. An intermediate pH measurement last year was ~8.0. It appears to me that the pH of the dexcool decreases with usage. I believe this increase to acidity is the reason for the damage to the intake manifold gaskets.

    2000 buick lesabre with 53,000 miles (from deceased parent).
    $4,500 repair bill estimate.
    5 repairs listed ~ stemming from coolant leak…. to intake manifold leak, thermostat, radiator hoses, etc
    guess 10/2012 is too late.
    since lawyers fixed it so deadline for registration instead of open ended (if possible) AND since they received over $18,000,000 of the $24,200,000 settlement (what judge/court got paid off to okay that kind of % lawyer share?)….
    LETS GO AFTER THE LAWYERS who, along with GM should have researched, via vehicle registration, ownership for notification.
    We are all nervous to post personal contact info.
    Does anyone know how to set up a facebook page relating to this? im not computer savvy. i will try my best to research options. i will check back here to see further comments & will post what i come up with.

    Hello all…..I understand and did not know about this lawsuit at all. Bought a 1999 Chevy Venture last year and I am a single mom of four kids. Now we have no vehicle to get anywhere. I spent $3200 on this stupid van last year and I have had so many problems. I has been in the shop seven times since I have purchased it. I don’t have the means to pay for this car anymore. I have a friend who is a lawyer and I am going to check into this further. This is neglect on GM’s part for anyone and also if it was such a problem with these vehicle and the money they are obligated to pay to the people who supply this company with business than why don’t they get smart and take all of these vehicles that are causing the issues off the market and allow the ones who have these POS cars to come in and trade for the amount that was paid on the current POS vehicle or give them their money back period. I will be sure to let everyone know that GM is not worth getting a car from or even to waste your time dealing with. GM is robbing people of their money and in my case they are robbing my children from having what they deserve. So thanks GM for the POS you made.

    I myself am a owner of a pos gm, I’ve replaced 2 engines so far! I WAS NOT notified of this. I’m in need of the 3rd right now, so glad I came across this! Time to scrap this gm and buy a ford! Thanks GM for NOTHING I’m not like your CEOs and earn a 6 and 7 figure salary!

    In 2004, I bought new 2004 GMC pick up truck 1500 8 cylinder 4.8 engine. The vehicle came with DEX-COOL coolant. Three or four years ago on a cold morning when I would start the truck it sounded like a diesel engine. I added coolant and it stopped. Since then, every month, I would have to add more coolant to the container. I did not see any leaks. I changed my oil every 3,000 miles. Two months ago, I had an oil change and oil would not come out. It was full of sludge. Yesterday, less than 3,000 miles I had another oil change and again full of sludge. I never knew about this lawsuit or the issue involving DEX-COOL.

    OMFG. and I just bought a 2004 Pontiac grand am se1 a few months ago and I just found some of that damn sludge in my recovery tank and it just tried to over heat for the 1st time. You better believe I am going to back flush the cooling system and get that sludge out of there big time and you can believe it that if that shit destroys my car that I wont piss and moan like these other people I will BRING ABOUT THE BIGGEST LAWSUIT THOSE GM PEOPLE EVER SAW. And I am not joking either. I do not play games and I will not tolerate an bs. I was just recently involved in a car accident involving a 2002 pontiac grand am se1 where the air bags did not deploy until after I was seriously injured by slamming my head arm and hand into the front windshield and cracking it. This is 2015 and its time to give GM a payback like they have never seen.
