Exterior/Interior Rust

[royalkangaroo]

I know this topic has been brought up previous times before, but I'm looking for a little insight and/or recommendations.

I've got a 2010 Silverado 1500 All Star Edition with only 49,000 miles. The frame coating is peeling severely throughout the whole frame, and showing bright orange rust. Even interior components are corroding near the brake pedal and such. (see photos)

I know there's a TSB for 2011-2013 regarding this, but it seems like just re-coating over the rust wouldn't be very beneficial. It seems like the only solution is to strip, prep, and POR15 the whole frame. Even though I live in Vermont, it seems crazy how fast it's deteriorating. I've seen plenty of older trucks in much better shape.

Anyway, enough venting. Any ideas?

What's that bottom picture of? I'm thinking the middle one is trailer hitch?

It doesn't look pretty and is a defect in GM's engineering in my opinion. You are well on your way to what my 2001 looks like. This is another long standing problem GM is doing it's best to avoid.

Go for the throat. GM is totally at fault. I don't think the TSB said anything about coating over the rust. There was also a pre-prep to deal with the corroded frame before the new coating. The TSB was posted on this site in the last few weeks.

You are in deep doo-doo living in Vermont. As far as GM is concerned you shouldn't even drive your truck in the salt air from the ocean, lol.

I see a buy back program similar to Toyota in the future if they don't get a handle on this

2nd picture is down by the brake pedal in the cab. 3rd is the corner of the rear cross-member where the hitch is located. 4th is the main frame rail where the bed meets the cab.

 

I agree on the buy back.. this is just plain ridiculous. Only 49,000 miles! There's got to be a way GM can redesign the frame coating for longevity. I know salted roads is just a killer on vehicles, but you can see 2014's in the show room with rust starting at the corners of the frame and differential already.

 

I'm going to contact my local dealership to see what some options are.

 

Maybe the best idea is to start leasing. No sense in owning a vehicle that's going to deteriorate in less than a decade.

I started a thread about the frame rust a few weeks back. I have to schedule my appointment, although mine is a much smaller area.

c0boy,

 

How did you go about contacting GM?

Holy toledo, I think GM forgot to put the frame protection on your truck in the first place. My '06 hasn't seen anyplace where they use salt but I drove it for two years in Alaska and my frame and interior parts have only got surface rust on them, at most. A good portion of the original high temp wax coating is still in place but it's getting more and more depleted over the years. I also have a '76 Chevy pickup that looks only moderately worse than that and that was driven all over roads of Pennsylvania. I would most certainly be getting GM to do something for you. There are a few of the GM Assistance folks on this site that will gladly help you.

Your 76 had twice the steel thickness in the frame. A corrosion allowance. My 68 Chev frame, which is now a trailer, corroded has more metal then my 2001. GM put a defective anti-rust coating on the frame and took away the corrosion allowance to reduce weight and improve gas mileage. This would be ok if the corrosion protection worked.

I had my box off last summer to replace all the brake lines. Take a look at what an 01 frame looks like. I replaced a shackle this winter that rusted through and snapped. Waiting for better weather to replace the other one. BTW I have a beautiful Class IV Reese hitch attached to that frame. I can see my camper and ass end detaching in my rear view mirror some day.

My body panels are in good shape except for the rockers which blew out one month after the warranty on them ran out. But the while thing is sitting on a rusted and totally suspect frame. Next thing to go is my shock mounts and there won't be enough metal left on the frame to weld new ones on. Totally sad.

Seems like only a few more years and my 2010 will look like that, Bruce.

[brucelimerick]

All my new vehicles I undercoat and use 3M stone guard on the rockers right off the lot. Mud flaps I would recommend too, my rocker damage was mostly due to stone chips, can't fault GM for that. I always washed the underside of this truck better than the top especially in the spring.

The frame is another story though. GM voids the corrosion warranty if you use undercoating. Problem is their coating doesn't stay on. If it is a waxed based compound you can see their point, I would assume some of the undercoatings would dissolve the wax. Knowing what I know now I would have been after the dealer to get my coating fixed where it had peeled before it came off warranty. That's what I recommend to everyone with the problem. There is a TSB so it is on GM's radar. The only way they will do better is by making it economically hurt them. You are only getting what you thought you paid for. I get a little pissed when I read about people with trucks just a couple of years old still having these troubles. GM has had this issue at least a decade and has done nothing so far.

I do know my next truck won't be GM unless they solve this problem.

My stock aluminum drive shaft and special stainless steel exhaust just gleam like new. Plastic gas tank perfect except for the steel straps. Won't do me much good when the rear wheels literally fall off this truck. How can that not be a safety issue?

You'd think with those of us that deal with winters and those that deal with salt water that someone would find a coating for under neath that is impenetrable

Bottom line is that they do not want them to last, so that you will go buy their latest and greatest. Salt is nasty, and will eventually kill every vehicle that is subjected to it. That is why it is not used on airport runways. You wouldn't want to see landing gear rust off a plane. The wax coating is not one of their smarter ideas.

I just undercoat annually can't lose sleep over GM and their dumb ideas... Too bad we don't have rot out issues like Toyota maybe they'd do something then

Man, that frame picture looks bad. Almost like some sort of a metal charge (as in electricity) issue or something that is actually accelerating the rust. That is insane!

 

Having said all of this, I have heard that the liquid solution that they spray on roads now actually is way worse than even the granular salt.
