spent the night at the dealer and so far, they are thinking head gaskets. more test to come monday along with pulling glow plugs, etc. I'm not happy, brand new truck... hopefully hear from GM rep after mondays test.

8 months old and 15,xxx on the clock, should this mean a new truck?
 
Nope. Don't get your hopes up about getting a new truck or a new motor even. They get a few opportunities to fix it before you would have to start a lemon law claim to get it bought out.

4th time its been to the shop for the coolant issue. if they fix it, should i be getting an extended warranty? should i be putting head studs in it if they will let me?
 
After the third time that the vehicle's issue was not resolved and the customer is not satisfied a written certified letter is to be sent to gm stating the issues and they have one more chance to fix the issue. If it is not fixed they can buy back the vehicle for purchase price or replace with comparable model. This must all be done before the first 24 months of ownership

Thanks for the info everyone. Will see what happens after Mondays test. Its a major inconvenience as I'm working on the road and use my truck daily. If it's repaired I'll always have this issue in the back of my head

well, long story short. the head gaskets are blown. said there was a bulletin for poorly made gaskets and I apparently got a set. anyone else heard this? could anything else involving the motor cause the head gaskets to go bad?
 
Bad head gaskets on the 2015's.
That sucks did they say how many are affected?

didn't say, trying to get a copy of the bulletin that was talked about. truck has 15000 miles on it.
 
Well at least you know the problem now.
Hopefully they have you fixed up very soon and you don't have anymore issues!!
If you see the bulletin I know lots of us would like to see it.

Wow. I have be a 'GM' guy for my entire driving career. You spend $50k on a truck you expect a quality product. I remember when GM'S saying 'a mark of excellence' was quality. What now? Good luck and keep us posted.

if I get it, I'll get a copy up for others to see. I just hope that it's fixed 100% and there are not any other issues with it.
 
I would be making sure they check the deck of your heads, heard a lot of ps 6.0 heads that where just thrown on without checking them, they ended right back in the shop
 
I just talked to my GM buddy and he said he does not see a bulletin for bad head gaskets. Once you get the bulletin get the DOC ID # it is typically 7-8 characters printed on the top of every page of the bulletin. They might have a number but it does not look like they are being truthful.
 
Early 2011-12's had a TIB for head bolt problems, I wonder if this is what they are using?
 
I'm new to the forum my new duramax has 6500 miles on it and I had the same problem bad head gaskets should get mine back wensday took one week for them to get the gaskets and two weeks to change them they checked my heads and block made sure of it and they r fine

working on getting the "bulletin".... they will be starting tear down hopefully tomorrow am. said they have to order the gaskets after the heads are off to confirm which ones are needed? I believe I've heard that before.
