To buy or not to buy, on the last week to order a 2014. This frame coating is a big concern (live in Upstate NY), lots of salt. Anyone recently pick up their new truck, how's the coating look? Wondering if this is just on the first half production batch or just a "bad" process all together??

They're adding a thicker clear coating to the whole under carriage on top of the wax, axle, transfer cases, pretty much everything underneath. I'll post a couple pics of my newer 14 as soon as I get some time

Yes, please do, thank you. I still think I may wait and order a 2015 anyway, but nice to know GM is addressing the issue.

Nice change vendors on the wax coating to save a few bucks only to turn around and have to add a clear coat to protect the cheaper wax coat from coming off. I'd love to see the cost information on all of that and if GM is even saving any money at this point. What a bunch of morons.

I just received my 2014 SLT Crew Cab that I had ordered on February 15th. Naturally, one of the first things I did was check the wax coating on the frame. There is one spot where it looks like it has smeared or came in contact with something – possibly during the build process. Other than that, there are certain areas (IE: sharp edges or irregular surfaces) where the coating is very thin or not on at all. If my truck wasn’t leased, I’d be inclined to fix this myself. I’ll let the dealership deal with this though. After crawling underneath, and going over every corner of the frame, I am skeptical of this coating holding up under certain conditions (IE: gravel roads, Canadian winters). I'm a bit disappointed to experience this after spending $50,000 on this vehicle. This is frustrating as I had wanted something I could keep for 10 years but am not sure now. Just how serious of an issue could this become down the line? Personally, I really don’t know how this is fixable other than just redoing the entire frame. Thankfully, I have the option of just returning this after the lease is up…

Holly Molly, that's bad. Get that over to the dealership ASAP, I know where you're coming from I'm in Winnipeg.

I went through this with a 2011 Sierra. Traded it in myself because of a pathetic buy back offer and made out better.

 

The fanboys on another site ripped me for complaining, but its obvious there's a problem when a brand new truck has this issue sitting on the lot. I passed on a brand new '14 double cab at a great price that had the problem. First item I looked at on my new '14 Reg cab.

 

Three different plants are the suppliers of these frames, all use the same process. One plant is in Canada.

 

Another plant is in Kentucky, and another is in Mexico. Doesn't seem to matter. You might get a good coating on a frame.......you might not.

As a temporary fix, I wonder if covering these areas with something like clear Plastidip would be advisable? I say clear because at least you would be able to see what's happening underneath. Also, the Plastidip is easily removable before a more permanent solution is applied.....

Well, I didn't take it anywhere as I don't have a 2014, but I'm very very familiar with this issue, I redid my frame on my 2008 with por 15 from scratch. As for dealerships, I wouldn't take it to any Gauthiers here in Winnipeg, I worked for them, nuff said.

My truck came off the delivery truck and had an additional clear coating on the whole undercarriage and frame. Its not hard but you can touch the whole frame without getting wax on your hands. There were only 3 others like it at my dealer and all of them came off the latest delivery truck 2 weeks ago. My new truck build fate is 3/14, and I'm assuming all trucks after mine will have the better coating over the normal wax. It seems like it'll last a while now.

In your second picture right where you see that bolt head on the underside of the frame, to the left of the bolt was a problem area on my truck on both sides. It was as if there was painters tape there when they dipped the frame and then it peeled off and rusted. Can you see that spot on your frame and verify what it looks like? It looks like it's pealed slightly at the edge before the frame turns vertical facing the camera and that's what mine looks like. Sorry I don't mean to point something out that might bother you but just wanted to see why I had identical rust spots on both sides of the truck in the same location under the frame.

Its all smashed up and metal slightly exposed but sprayed over with the clear. No rust. I'm going to take some black spray paint and touch it up now lol. I bet its from when they stack them after the dipping process.

      Gas Prices

      By Grumpy Bear · Posted

      If we actually used any significant amount of that source in the USA then I'd agree but we don't. We've had that discussion before. We drill and pump more than we use. Thing is, we sell. We export. Gas and Crude. It's more profitable so any shortage here is self inflicted and LEGAL.    I worked a gas plant that has multiple fuel sources available and I worked in the furnace and boiler plant in that facility. I'd had days we swapped fuel types four times in a twelve hour shift which isn't done on supply but on margin. Two of the fuel sources are internally generated. Tail gas and DAK, both of which are sold as well a consumed. We always had more than we needed to run the process but we chose the fuel that produced the best margin not bought at the cheapest price always. A good bit of math to that and back in the time that was done on a slide rule.     I worked the Shale Oil Semiworks of Chevron Research and CONOCO Research in Salt Lake City. That process never went into production although it was very successful. Why? Did we lack oil bearing shale? Nope. Price of crude never made the margins work. That was in the late 70's early 80's. Remember history? What was happening then was a reaction to that situation. It didn't drive it. If so then it's easy. This isn't a supply and demand thing. This is a profit and margin thing and AI rules that now.    In no refining situation that I was ever in would a bomb hitting a well anywhere in the world 'instantly' interrupt or even distress the supply. Most plants have more than a months worth of crude in the tank field and more in pumping stations. That yo-yo could play out over days, weeks and maybe months and have zero impact on plant operations. How many times has this been off and on in the last few months? These people and not stupid. These plants measure down time in hundreds of thousands of dollars per day. They are not sucking fumes or waiting on the next truckload with baited breath. Besides, as I noted, they are for the most part 'vertically integrated'. They own it from the dirt is sits in to the delivery rack and sometimes to the pump. It has a HUGE shock absorber built in. When production suffers, refining wins and when refining is winning exploration is killing. The rest of that crap in the news is a 'news cycle'. Government dipping in to reserves? Oil is stealing their milk money. There's a reason Chevron abandon Venezuela infrastructure and it had nothing to do with security of US citizens. Nationals run those plants. it has to do with MARGINS disappearing to corruption. They are in no hurry to return. Is there supply there? Oh yea. More than enough to offset what is bought in the middle east. Just isn't ???? Profitable.    We have supply. There are places in Illinois you can drive a pipe into the ground and run your homes natural gas furnace on it.    A refinery fire will gum up the supply works but not a localized war where the market is using a limited supply from. Now Europe, that's something other....

      If we're talking futures, yes, it's speculation.   The spot price of a delivered barrel is elevated now compared to before the conflict. And that is related more to current supply/demand.

      SPECULATION on the wars effect raised prices. AI is maximizing the profit. Refining is vertically integrated.

      It's the Middle East conflict that raised prices, not AI. But nice distraction.
