Rusting Frame

[isubucky]

I'm watching this as well. I am disappointed with this issue, but suspect it is cosmetic, but I hate to wait and do nothing to be wrong.

Just got my truck back again after 7 days at the shop for other problems as well.

I brought my 2014 Sierra in for service in January because of frame rust. I knew it was a joke when they said it would only be an hour before it was ready. Now two months later all of the rust is showing through again. I called GMC's complaint number, and they just connected me back to the dealership who said I could bring it back in to have it re-coated. My dealership is certainly not removing and treating the rust areas before applying the seal coat, just spraying it black and giving it back to the customer.

AND THAT'S THE WHOLE IDEA. DO A SHODDY JOB SO YOU DO NOT COME BACK.

I wonder if you can spray the rust spots with Iron X to remove it and save the hastle of using a wire brush to get rid of it: http://www.amazon.com/Carpro-Iron-Remover-500-Ml/dp/B004UM6DLE

 

Then just spray the 3M rubberized coating over these areas after washing the Ironx X off. I used Iron X to get rid of rail dust on the body of my truck but I also sprayed it on a rust spot on a steel door on my house and it removed all of the rust from that spot.

 

EDIT: The product description does say:

 

• Iron X should not be used on chrome, bare metal parts, brake calipers, wheel balancing weights, or SMART paint repairs

So I dunno.......

Started to notice rust on my frame lately as its spring and I'm starting to wash and clean my truck more often. It seems to be mostly on areas where it was welded. I don't even know if its worth the hassle of trying to get the dealership to fix it. They will likely just say it's because of the salt from the winter.

 

Just another thought, I don't really care so much if the rust is only cosmetic and won't cause issues in the future. That being said, where I can see my frame in the rear wheel well is rusted, has anyone considered using a bedliner materials to cover just that area?

Mine is getting worse and it’s very frustrating – especially when you see Sierras and Silverados without this problem. Whenever I see someone’s 2014 or 2015 the first thing I do is check out the frame in the rear wheel well. I’ve contemplated taking it up with the dealer and bringing up the bulletin, but do I really want them taking off the box etc? I thought about giving the problem areas a shot of black Rustoleum or something, but this might make what’s left of the coating come off even faster. Hopefully this is just cosmetic. Regardless, it’s not a good feeling paying 50,000 for a vehicle and experiencing this issue on something that’s not even a year old. I guess it doesn’t hurt to try the dealer route and see what they say. In the meantime, have you thought about trying the plastic GM Wheel House Liners? I’m not sure if they go that far down to cover the frame but it might be worth it to look into..

That is 5 attempts to cover the rust and making it worse every time, I have rustproof over spray from running boards, to paint, tailgate, back chrome bumper, wheels, exhaust tip etc... and is falling off really bad.

mrp, that rusted bolt on a '14 does not look good! That is fast rusting. I live in south, so we don't have so much of a rust issue, but we still have rust. I hate rust on my trucks. I bought a used '93 Dakota in '97 with 47,000 miles from Ohio. It was treated by previous owner with that Ziebart stuff - WOW - it works!! I still have that Dakota with not a bit of rust! Love it.

I have been using fluid film to protect against rust and so far so good. I had a 5x5" spot where the wax didnt seem to be bonded to the metal. Painted with flat black paint and reapplied FF. I've been reapplying every 6 months or so. Not for everybody but works for me.

Is the fluid film softening the wax on your truck or not?? I would like to know because this is why I haven't put it on the wax. I have only been putting it bolts and nuts that need to be removed for maintenance, brake line ends/connections/bleeders, forged steel parts, tie rods, etc.

Yes fluid film will soften wax ,it did on mine

It made it slightly softer but never lost adhesion. Just one spot in the rear wheel well that looed suspicious before I even started putting FF on it. I'm not concerned about the wax. Every GM truck I have seen in person with this wax is begins to harden and crack, exposing the steel. Or water finds a bad spot in the wax that isn't visible and rust spreads under the wax. Last summer, while putting on my exhaust, I noticed that the sharp edges of all the drain holes on the bottom of the frame had wax that was peeling back and rust had started to spread underneath.

 

 

To be honest I wish the wax wasn't there at all because I would have been painting it with POR 15 and would never have to worry about it again.

Hi Guys, I just picked up one of the last 2014 Chevy Silverado's at my local dealer. The build date was Jan of 2014 and I noticed rust on the frame exactly like everyone in this post. After complaining to the dealer and sending info over regarding the TSB you all referenced GM will be completely removing the frame and re-coating it. I'm a little nervous that they will never get it back together properly, Has anyone else had this done? How long did it take? Any issues?

 

Thanks
