Did this video help you?

Thomas Martin: GM did the same thing on the LT1's in the 90's, broken bolts galore. Recall? Not a chance. The bean counters found a place to put in a low grade bolt instead of the tried and true exhaust bolts GM used for eons before. I finally after 25 years of buying GM, gave up on them. And generations before more me only bought GM. Now they buy Japanese cars. They won't look back.

Tomlin James: People need to just do it them selves and fix it right with parts they trust. I repaired my 5.3L a couple weeks ago with new bolts and anti seize.

Peter Grooms: I have a 2004 Tahoe 5.3 with a broken driver's side exhaust manifold bolt. I used a repair bracket ($22) and it sealed the leak! Easy to install, although you need to contort yourself a little to reach to the back of the engine. I agree it's a problem, although I've found the aftermarket provides cheap solutions (Kral, Dorman).

Terry Thomas: Our 2002 Astra Chevrolet 105,000 kms 2 Missing Manifold bolts ! Cheers GM !

V. L. Moore: Carquestions I saw your video about the bolts breaking on that GMC Sierra, I have a 2005 GMC Sierra 5.3 L and I have the some problem with my truck. I will be contacting someone about this problem. Thanks

Kevin Rogers: like really? this is an extreamly simple job to repair, thos broken bolts where it is not flush with the head they are extreamly easy to do, its not a defect simply because its expected to happen, you have different expansion rates with the manifold, and head, and lets not forget about the rust factor in behind the bolt head pushing on the bolt, which causes the stress on the bolts and they snap, Ram and ford both have the same issues and fords are a total nightmare to do, ram is a pain as well but not nearly as bad, i can do BOTH manifolds with broken bolts in 3 hours EASY, you dont need to pull the inner fener out, very simple job if your expernced. just an FYI 2.4's manifolds crack sometimes, 4.3 sometimes leak, 3.5 and 4.2l are horrable for the manifold cracking down in the webbing of manifold, 6.2L in half tons and ESV's its an expected issue with anything the amount of heat and power thes engines produce expecally bering DI now, then whoever tows can see this more

Nevadaiscorrupt: Cousin has an 01 GMC. Four bolts are broke. 3 out of 4 trucks I have looked at have broken bolts. Next truck I buy is Toyota.

Nevadaiscorrupt: I watched your video and decided to go look at the bolts on my 06 GMC Sierra. Sure enough one is broke. Thanks for the video. I will file a complaint but doubt it will do any good.

koolpimp2012: Just ran into the same problem looking at $1300 for one bolt on each side :/

Toluene: See the problem is they really don't cause a safety issue. I bought an 02 Tahoe and it had the same problem so I went and bought a nice set of easy outs (or whatever they were called) and got them out. It's hard to get them out because they have that thread locker on the bolts. They are a pain! GMC/Chevy aren't the only ones with this problem either. I had this problem with the wife's 06 Durango and my '98 Expedition. I'll do a video for removing these broken bolts when I get the time.

Nevadaiscorrupt: My dad has a 02 Chevy Silverado So I looked at his, it has a broken bolt also. I also have an 05 sierra all bolts intact for now.

drens rob: I got 2 bolt missing on driver side would that make the catalytic converter to make noise like a fast knocking noise

Shane Brough: I own a 1999 Silverado z71 5.3L, I had this problem on the 2 back bolts on the drivers side exhaust manifold, one bolt was sheared off into the head. I had the problem fixed, and within a year the have broken again. It's not a cheap fix and the shop claims they used grade 8 bolts. I am still able to pass emissions in Ontario, it hasn't thrown a code yet, but it's probably just a matter of time. For now I just have to deal with the "tick" until the engine heats up and seals again. This should be fixed, GM reuses a lot of parts between different vehicles, and this is an issue that carries through many different models.

Cindy Barber: I am having the same problem with my 2008 Envoy Denali. It has the 5.3 V8. I contacted GMC about this problem after watching your video and they are giving me the run around. Do you know it there is any one working on a class action lawsuit? I have 2 broken bolts on one side and 1 on the other. I only have 118,000 miles on it. Is there anything that you know of that would be helpful I would much appreciate your feed back. Thank you and anyone else that has any suggestions. 

John Jones: GM is finally forced to step up to the plate. The recalls are mounting. I will take my 1996 K1500 over any new GM product. 

Edward Ingram: I have a 2006 hummer and I have at least 3 bolts missing

Scott Beydler: https://www.facebook.com/media/set/?set=a.557764230990982.1073741835.349520098482064&type=1 

Brian Stenson: I have same damn problem with mine a 1999 gmc sierra 5.3l. 4 bolts total broken, on L and R side towards the back. Step up GM

peacenlove0101: GM needs to take it easy on threadlock they use it on everything .

harjot nijjar: i have this same problem on my 06 gmc 2500hd, Do you know if gm has said anything about this? have they done any recall ?

rsundstrom7: This just happened to me, by of course coming to youtube for solutions, I found this vid, I have filed a complaint. Amazing how many people are having this same issue.

Theo Butter: As we know (2014 ignition switch revelations) GM will never recall anything even after several deaths. Buy a Kia.

Todd Randall: I've got a 2004 5.3L in my Yukon XL that I've owned since new (every service done) with this exact problem. It has 107,000 miles of soccer mom driving on it in southern California (not the rust belt) with a few boat tow trips in the last couple of years. GM has a TSB on it # 06-06-02-026 that I found here http://www.nastyz28.com/forum/showthread.php?t=167260&page=2 half way down the page stating to use larger head bolts. Dealer is stating $600 if it's "easy" and close to $1800 if they need to pull the head to extract the bolt. Multiple Chevy and GM forums with mechanics stating there is no need to pull the head....

Trent John: @ thebluetarp who is charging you $1000 to replace 6 bolts. I could do that work in my driveway and I know that 6 studs don't cost much

Lou's Custom Exhaust: As an exhaust specialist I will tell you this much, it is not isolated to GM cars. F150's are notorious for snapping the manifold studs on the passenger side manifold, Toyotas have a "always breaks" bolt as well. As a side note I use the same code scanner and that code would be from your passenger side manifold leaking for sure (p0430). As you said the broken bolt does and can cause your converter to fail by allowing more unburnt fuel down into the converter. The lack of backpressure from the leak is what causes the unburnt fuel condition. 

Soleil: I have a 2008 2500 Silverado and the back bolt driver side broke off. Went to my local mechanic and he could not remove the old bolt as it broke off deep inside. Replaced the manifold without the back bolt one month later the noise is back and it is worse. They have been in our community for years and mine for the past two years. How do I get my money back?. My local GM dealer quoted me a price of $1800 to fix it if they could not get the bolt out. Can they get the bolt out if it is broken off inside the engine? Also a company called Kral Auto Parts out of the States, has a part that they say will fix the problem without having to pay the big bucks. Have you heard of them? http://www.kralautoparts.com I will send in my complaint but would like some feedback, please, on my two questions above. Thanks Mark

Mac S: A bolt is hardly a major recall

surfertube44: Agreed! I just found 2 broken bolts and spent hundreds of dollars trying to fix a miss fire, this is bullcrap and also when they break off where do the land, in somebodies windshield causing an accident? they need a full recall NOW, also there " Lasts the Life time of the vehicle" found out its 10 years ,not the engine but all surrounding parts of the truck, at least my truck survived the 10 with out major problems since 2000 C 3500 5.7 but there recalling the 2014s already for catching fire! 

a lilly: The best way to fix this major problem is to go to www.kralautoparts.com. I have a `03 Silvarado that had the back bolts broke of my exhaust manifold. I found them and installed my bracket from these guys two years ago and it still works great. It installs quick into existing holes on the back side of the cylinder head. I highly recommend this for your fix on many types of vehicles. Check out their website, or Facebook to see if it will work on your vehicle.

Andy Hassan: I have a 2007 Chevy Tahoe. Truck is in shop now and I am beyond pissed that I have to pay for this obvious manufacturing flaw. Suggestions ? 

thebluetarp: ABOUT to spend $1,000 to have my broken bolt on my 2003 Tahoe fixed. but, while they are in there they are going to replace all 6. anyone know what else can be fixed, looked at or replaced while this work is being done??

Scott Fuller: I support this video all the way my dad has a 1999 with a 5.3 with 3 broken bolts I also have a 2000 with a 6.0 with 2 my neighbor has a 2002 avalanche with a 5.3 with 3 and my new 2007 has 2 I have fixed 2 out of the 4 trucks and its no cake walk doing it and its getting old fixing this when it sould be a recall

Scott Harris: I have some broke on a 2003 with a 6.0 and its filling the cab with exhaust going to go check my 2000 5.3 right now

Steven Lees: I'm 16 and I fixed it my self on my 2001 gmc yukon. It took 45 mins and I was done it's not a freaking problem 

ThE cHicKeN cHaNnEl Fowl Play!: No kidding! Design Flaw. Costly to people who can't do it themselves.

Billy Mac: Easy fix, as said in the past, take off tires and maybe wheel tubs, get a mig welder and some 3/8 or 7/16 steel nuts and washers, using the mig welder weld a big blob onto the broken stud, don't worry the mig welder wont weld to the cast iron head and the exhaust manifold, it wont ruin the stud threads either because of dissimilar metals and the red hot stud now will burn off the loctite compound. After you weld a blob of metal past the exhaust manifold put a nut on the top of it and center it to put a socket or wrench on the nut while holding it with pliers, you then mig weld bead in the middle of the nut to secure the nut on the blob of metal you just welded, you can weld a washer also facing sideways and here is the best part, after all that heat the bolt will unscrew from the head easily every time,you don't even need a socket most of the time, just be careful it will be very hot for a while, I have done this twice on my 2000 2500 6.0 None of the slag from the welding will stick to any of the cast iron, so its a perfect job and you can get to all the bolts easily, using an argon gas wire feed welder is best for this job instead of a flux coated wire, use the welder at a high temp setting !

GaianUNSTV: I'm hoping to do my own repair any youtube videos or recommendations you could make.

carquestions .: So much for it just being a problem in "salt belt" areas - thanks for filing the complaint and take some solace in the fact your comment will be here for years to come.

dandanzoo: I have a broken manifold bolt on my 2004 Yukon denali. Its a good excuse to throw a pair of Gibson stainless steel headers! Its going to be a cunt to get that out idk if im going to attempt that.

carquestions .: You summed it up nicely

carquestions .: @chuffo302stang Thanks for the comment - you couldn't be more right.

Tim Blagden: @shipmate5967 I did on July 21, 2010. NHTSA said to go to their Safercar.gov site and file a defect complaint. They also recommended contacting the FTC which I did. Another easy form to complete. The third suggestion was to contact the state attorney general's office.

squibbles0: you probably made this up

carquestions .: Read comments below - some have paid more

carquestions .: @1970gtosd You're right it is a very big problem with Ford and they are doing their very best at ignoring it - hopefully I'll be detailing it in a new video this year.

trackstrbrotha: I took the Head off and put a washer over the broken bolt. Make sure the inside diameter of washer is smaller then the bolt. Take a welder and weld the inside of the washer to the bolt. Then cut the head off of a larger diameter bolt and weld the head onto the washer. Then unscrew it. Worked on both of my broken bolts......

frankt04: I have an 03 silverado 4.8, 3 bolts snapped on driver side 4 on passenger side, you know what I'm doing in spring

bob larson: its because it was build in canada and thats says it all

shipmate5967: I have a 2003 Silverado 6 cylinder that has this same problem. I took it to the garage and they showed me the missing bolt & my engine light is also on. I already know that it won't pass the emissions test & the cost will be well over $1000. So there's no current recall and this is money I don't have to fix this problem. It probably will take forever to start the recall process and it probably won't get anywhere. I've always been a GM fan, but I probably won't buy a GM vehicle anymore.

JL H: Yo por experiencia les puedo decir que el xperia Z1 tiene buenas especificaciones pero una vez que lo tienes en la mano no es tanto lo que promete, ami me desilusionó mucho el sony Z1 porque su pantalla es muy blanca y gris sus colores son demasiado opacos, tiene buena camara pero nunca vas apreciar las fotos en tu celular, el celular por default te da muchas imagenes pixeleadas, se calienta mucho cuando lo tienes manejando al full, su cámara de video es horrible pixelea demasiado la imagen, su camara de 20mp no es tan buena parece de una de 6 mp lo único que hace es procesar la imagen y estirar el color pero no da una definición real, cuando lo tienes conectado siente en la parte de atrás como si se inflara y parece que va explotar. Su procesador snapdragon 800 va rapidísimo lo admito pero al final el 80% de las veces aparecía con error o no bajaba el documento. Sony me dejo sumamente molesto y tuve que cambiar al Samsung s4 y no tengo ningún problema.
