I expect the dealer will do the TSB under warranty.

 

Here is where I'm at:

1) noticed peeling at 3200 miles.

2) sent pictures to Manager. Took it in for 3 day treatment

3) picked it up. Pointed out that they only did about 50% of frame.

4) they took it back for another day. Did a half ass job. Sprayed over rust.

5) the band aid coating starting peeling off on a couple spots within a week

6) now I treat the exposed areas myself.

 

Plan on taking it in right before warranty expires and have the re-do the whole thing

Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

Hopefully the dealers get fed up with these tsb bandaids and make enough noise that GM ditches the shitty wax coating.

After a year, you'd hope they've already addressed the issue with the 2015 trucks.

 

I've been poking around reading about this 'wax' coating and the rust issues - and I haven't seen any complaints on 2015's.

 

It's a shame you guys have gotta deal with that. And like I said... send some emails or phone GMC/Chevy Corporate and complain. You can tell them that "Toyota is replacing frames due to rust issues". WHAT CAN YOU DO FOR ME and keep me in a GM truck?

 

Whatever it takes to put a bug up their ass! LOL

Wax doesn't chip like paint.

It just peels off like wax, especially after you apply it to a rusty surface.

Gm has used this wax shit for decades... my 86 Blazer would have had it but it's been gone for decades. Local dealer has an 86 Chev 4x4 1/2 ton they put in the show room every year... has just over 100 original miles... it's a time capsule. It's frame wax looks pretty good though lol!

Yes, it certainly seems there was a problem with the process which resulted in poorer than normal adhesion.

Yeah you gotta stay on top of the undercoating if you don't want rust. Read the multiple threads on here that discuss the problems and solutions to it. I drive my truck through salt all winter and washed the frame off maybe twice all that time. Zero rust other than a couple spots hidden by the spare. You can't rely on the factory wax. It's basically good enough to keep the frame from rusting before you get it home from the dealer.

And in case the frame already had surface rust on it when coated with wax at the factory, the wax will last long enough to hide the rust until you get the truck home. :bs:

Is this issue continuing on the 15s just bought a 15 serria all terrain about two weeks ago and looks good as of now. The only spots I have seen any rust is the bottom of the frame, were a guy would lift the truck up on a hoist. Were the pads would touch the frame and scuffed the wax coating. Other then that looks good.

Yep there are a few of us with 2015s that have this issue. Just keep a close eye on it. Sounds like you are in the clear. It usually starts peeling off in big chunks within 5k miles.

i got 5k miles on my 15 Built in may. wax is holding up really well. "knock on wood" ... Not to worried tho i always wash under my truck regularly i had a 04 and it had zero body rot, Very little frame surface rust when i finally traded it in. only thing that rotted out on that was the brake lines :banghead:

thank you for this post, I am so frustrated with GM as I am having the same problem. black 2014 gmc all terrain front metal bumpers paint is chipping off in flecks about dime size or better. Local Dealer said tough and im sol. Dealer sold it to me said bring it back and he would see what he could do but it sounds like rock chips. I've had 30 trucks never had a bumper look like this. Anyone find resolution to this? What a sad representation by gm.

      Some Assembly is Required

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
