Good question, it does not appear to be coming off in sheets . I have no rust as I am getting out of storage. That said I am going to spray all my cab mounts and any perches welded on frame . Daubert say 6 to 8 mil thick for best protection. My opinion is these areas have coating that is closer to 4 mill thick not 7 or 8.

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

Yea I'm not sure if I should take it in or not. This is a 3 month old truck though..

I wonder what that shit does to the water and environment. I'm personally for the idea of using nothing or very little. Most people shouldn't be on the road when it snows. They suck at driving.

I wonder the same thing, it can't be good for drinking water. I wish they'd just go back to plowing and that's it.

Rust will always be an issue for any truck, even the aluminum wonder truck. Keeeping rust away is ultimately up to the owner.

Ultimately, yes. I can see a little rust. I am sure that most owners would accept it without too much fuss. My main issue is GM telling me it's "normal." If I can crawl under my wife's 2010 Avalanche and it looks a little better after 100,000 miles than mine at 8,000 I am going to take issue with it. It is logical to assume that there is or was a difference in some of the frames either not getting cleaned prior to dipping or a problem with the dip coating itself. A company should just own up to it. That is how you keep longtime customers and make them happy.

The dip product may not be exactly the same as the 'touch up' product.

Yes good point . Even tho it is same product it could be different mfg. All the reading I have read on the hot wax dip is the actual temperature as it relates to thickness. Wax temp. to low it don't flow well over everything on dip. Wax temp. to high and flows good but dry thickness may only be 4 or 5 mil thick. Daubert say 7or8 mil dry thickness is ideal and best durability without premature ''washout'' much like a paint won't last very long applied lighter than mfg spec. My frame looks like it is reasonable thickness except during MFG assembly of vehicle where it was held or clamped . Them marred surface areas it looks like they just smeared off surrounding area and smeared it over the scare . Some of my vertical frame perches and mounts look not as thick as frame too. I will beef them areas up with more wax and see what happens I guess.

Frames are stacked, with spacers between them, when loaded on the railcars for trip from supplier to assembly plant. Some of the smearing may be at the spacer locations.

Was at a Chevrolet dealer today and looked at a couple of frames of used trucks through the rear wheel wells. Two 2016s looked pretty good while one 2014/2015 looked atrocious. I've seen better frames on 10 year old trucks. It had a nice bright orange patina on the frame.

Do you guys think this rust is bad enough to address with my dealer? On the fence about it.

Yes let me know! I'm going to at least bring it up when I'm in for my oil change in May. Get in on record in case it gets bad. The 2014/2015 I saw today had rust in the same areas but 10x worse.

There are some members here who had rust like the truck was sitting in the ocean floor bed. Mine never got so bad. One thing you want to check because I looked when I was taking pictures as proof. check the area around where they put the bars to raise your truck to do the oil change or inspection. I found those areas the wax was completely removed and rust taken hold. Very shocked by that.

This is what mine looks like directly underneath the truck.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
