Mine cost $2063.34 Total under warranty.  It was a 6.2.  Parts $818.76 Labor $1244.58

 

Oil changed every 7K.  I drive 30K miles/year

 

I picked it up when ready and drove to the GMC dealer and traded it in.

Ya the first time the first dealer repairs it cost $2500 with labor and all . So I asked why they are $3200 . Said labor is $120 here and only $80 over there . Smh . But he says it comes with a 2 year warranty now . I’ve always had good luck with my gmc . But **** this truck . I’ll probably do the same

Never have towed with it 
and yes I did the cylinder deactivate on it after reading up on lifters going on the first time . 
I’m running a leveling kit on 33s same stock rims 
oil changes done every 2500-3k miles . Full synthetic 
i baby this truck ! 

Within what mileage did you actually do the AFM deactivation?

I’ve said it time and time again, call your local media station and let them know everything that’s been going on, dealership and GM will fold rather than having bad publicity.

This^^^ sorry to say but it is your best bet financially.

Yeah, I know some don't but his first failure WAS covered, now suddenly they are not. I know or suspect he is past warranty, but MOST times if you have a repeat failure after a warranty repair they will at least work with you. Obviously his dealer isn't and so far GM is not either. It is what it is but lifters at some point fell under the PT warranty. Extended is a crap shoot IMO and yes I have one.

I’ve had many extended warranty’s. I’ve only had three total extended warranty repairs. Those three more than paid for all my extended warranty’s, a V-10 Ram engine was one. A bad injector o -ring, a lean out blown piston, past normal warranty. One decline. An 80$ part for anti lock brakes. A Ford backed extended. I went to that Ford dealer for 10 years with 5 GM trucks and 3 non Ford cars to show them what the lost. I also canceled a T-bird I had on order. That 80$ part cost them.

If it were me I would have it towed from that dealership and here is why. They repaired under warranty and 20,000 miles later problems on same bank again. A good dealer would supply the labor and try to get GM to foot some parts . If GM won't he could offer parts for repair to you at a discount off list price. In realty his tech cost him probably 30 or so per hour . Lets say 30 x12 hr. for example . For 400dollars of his labor and you buying parts worst case it could still be a win win for both. Seems like dealer is throwing the baby out with the bath water and telling you tough sh.t. 

Ya my situation forced me to keep it there . The town only had this gmc/Chevy dealer and the closest one to them was 2hours away . I was hoping I could least get parts paid or something . Even labor . I’m still waiting on a call back from gmc ! I’m picking the truck up this morning . Paying the $3200 . And hoping gmc makes it right and least covers something

Right after the first time it did it . Not 100% sure on miles but it’s been little over a year since I did it 

[Snowcamo]

Dude it will fail again. Trade that turd in

Reason I’m asking is that it must have been near failing before you deactivated the AFM. It’s a 15 meaning it took you a few years till you did it which is what I’ve been noticing. It’s been a rather long commitment GM’s been having to deal with.

What product did you use to turn cylinder deactivation off?

Did they have anything to say about that in regards to your claim?

Well you’ll be good for two more years now.  Keep it for 23 months and then decide what to do.  If I wanted to keep the truck, at that point I’d look into a new engine or a major rebuild. It would still be cost effective versus buying a new truck..

Did they mention anything about your tune as being the reason for denying warranty and did you disable it prior to bringing it to service?? Questions every mod enthusiast wants to know.

You have a really nice looking truck. Keep it for now and pay it off. You have 24 months of warranty to decide what you want to do. You could also consider an extended warranty if you decide to keep it. Several threads on how to get the best deal on the warranty.
