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

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.

    • HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.      
    • I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it. 
    • So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29. 
    • Any grease on the stud threads of any kind?   Wheel studs should have NOTHING on them for proper torquing and so the nuts don't back off.     Are all of the mating surfaces clean?  So wheel, rotor and hub?     We've had plenty of trucks at work with that wheel, this is a first to me.  Makes me think they've got a lube tech putting anti-seize on all the wheel studs or some kind of grease, and they need to stop doing that.  To have 11 other trucks with the same exact problem.      
    • I was a Chevy guy for years, then switched to GMC because I liked the looks better.  I'm actually thinking I like the Chevy looks better than GMC for the first time in a lot of years.   One thing I know for certain, the new GMC dash is hideous!  Chevy wins this one!
