You're probably right, which is why I'm not holding my breath. I've ordered some rust encapsulator paint and plan on doing my frame sometime in the next couple weeks.

Most likely. I swear this is the last first edition vehicle I ever buy from any manufacturer. If it hasn't been out for at least a model year or 2, I'm walking away.

My 2014 Silverado z71 ltz was a lemon. The frame rust was the final straw. I fixed mine by trading it in on a new ram. After 25 years of GM trucks, I have to say that it was like losing an old frien

2015 Ram Sport Crew Cab 1500 4x4. Love it. My Silverado started showing problems after day one, little things, then bigger, then frame rust and that was enough for me. Took a loss, but I walso

yeah I'm looking into the stuff from GM which is a rubberized type coating. Be careful with paint I read somewhere that can cause the wax to peel off if you coat the wax with it. You're only supposed to treat bare metal spots with any paint. Again I read that somewhere though I do not have first hand experience with any of this. This is the stuff from GM:

The wax was gone a long time ago on my truck. The entire frame is pretty much all orange. Rust encapsulator is supposed to wick moisture away from the rust, so I will probably put it on, then some black paint and then maybe something like the gm spray.

If your wax is gone that bad you should qualify for the proper TSB fix of re-coating the entire frame with that 3 part system that takes like 72 hours to perform. Mine didn't qualify for that the dealer just hit the rust spots with some 3M rubberized coating.

In Canada GM are using a product from Lloyds called Kryptonite

I'm out of bumper to bumper warranty. I don't think that tsb applies to emissions or drive train. Edited by projectsummit

Oh I see. Well keep us posted on how it turns out. Good luck!

I already went under and delt with the rust same as I have with all of my vehicles.

 

Hand Wash the unserside and rust paint over anywhere rust is starting.

 

The wax coating is useless I found three sports it just simply fell off of in large chucks.

 

Most of the paint on the rear axel was gone already as well. so painted that as well.

 

Just imagine how far a power coated frame would go GM.

 

I have a 2002 Coleman Camper with a powered coated frame and it has 0 rust on it after 13 years.

Which is good considering it sits outside 365 days a year.

I just came across this : https://www.daubertchemical.com/store/product-list/corrosion-prevention/nox-rust-x-121b

 

That appears to be the product to patch the wax coating if you need to touch it up. I think I'm going to order a can.

 

 

EDIT: Just went ahead and bought a can. It was about $28 with shipping. I'll touch up the rust spots on the frame the next time I get a free weekend to get under there and work on it.

That product used to be available at the dealers for frame touch-up. Don't know if it's still available through GM.

Yeah I thought about calling the parts department and asking but got lazy with how easy it was to just check out and have it shipped haha. It very well could be available at the dealers.

WOW

GM customer care told me to contact a different dealer to look at my truck and fix it.

New dealer ran my VIN and there was already a claim made for the undercoating fix so they won't touch it.

 

This is a pain in the A$$!!

Why not galvanize or powder coat the frames and charge the customer for it? I would gladly pay a little more to know I have something that will last. It pisses me off how they cut corners on stuff like this to save a few bucks. Now ill always have to worry about this thing rusting and having structural issues because of it.

WELL STATED,!!! I'd pay an extra 10% to have top quality materials & corrosion resistant treatments. Galvanize & coat under coat the frames & bodies, Stainless fluid lines, Imron paint in the bed box, etc.

 

i wonder how much of the quality drop is due to forced government environment regulation? Either way, quality chasis & coachwork is almost non existant on most new vehicles, especially by GM.

 

Their procurement & engineering are bottom feeders in this area.

Regarding the wax peeling, it may be due to lubricants used in the manufacturing of the frames. There is a lubricant used during the hydroforming process which allows the steel to conform to the mandrel (mold) without damage. My hunch is that the lubricant was not fully removed when the frame was dipped.

 

I believe GM at one point used Magna Industries to supply their frames.

 

A contrubuting factor to rapid rust growth may be with recycled steel commonly used today and it's high strength requirements (unlike milder, thick frames of the past).

 

 

. When GM switched from a ladder/rivit fram to Hydro Formed frame.

Hit the nail on the head here.. Chances are better then not that it is a supplier issue using a type of lubricant/coolant that is not GM specified and the only way GM could have picked it up was using some kind of FTIR gun to test it for unwanted contaminates before assembly/waxing... Hell I bet GM isn't even doing the wax in house.. So before GM gets a group of people with pitchforks and torches on there front yard give them a chance to render the situation right...

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
