Frame rusting

Dusty734 · July 12, 2019

I have a 2013 Sierra with a little over 105000 miles . Body is rust free does have some paint flaking. In March at 100800 miles I we underneath for a gas tank sensor. I found a hole in the left frame rail, approximately 4 inches x 1 inch . I contacted GM . There answer was you perforation warranty expired November or 100400 miles which ever came first after several week they offered a service voucher for $100. I declined, I am going to keep fighting. The whole frame is in terrible condition. My 2008 has surface rust but nothing like the 2013.

I pressure washed the underneath the other day to make a repair. I found the rust to be much more extensive nearly 18 inches long. Disgusted with GM this is my 16th and 8 brand new GM product, probably the last

That is some crazy rust on that frame from a 2013 with 100000 miles. Looks like it is ready to fall apart.

I plan on using rust converter , etching primer , paint , and then spraying RP - 342 . I know from having old military surplus stuff that cosmoline is next impossible to remove without gasoline or some petroleum derivatives. I know soap , water , degreaser , or road water will remove it .

2010 Silverado, wheel wells rust coming from back side, bottom of the tailgate, bottom of the doors, paint coming off behind back bumper and bottom of the doors. I take care of my vehicles. Very disappointed with Chevy. My Silverado has been a great vehicle except for these issues. I'll never purchase another truck from Chevrolet.

That's fine, Chevrolet could care less if you do or not.

And that, folks, is the sad truth of it. Several hundred potential buyers come of age every hour. What do they need you for?

notice how the metal scales. Welcome to the world of boxed frames.

OUCH on that frame!

I live in Ontario and rust is an issue with all the salt.

I have a 2015 and have Krown Rust proofed it once a year since i got it and it has helped keep the rust down.

Is that a KTM in the back?

I check my frame & underbody spring and fall & treat as needed. I don't want this one to end up like my last one. It was an 06 & was pretty rusty underneath when I sold it.

I stopped by a dealership to look at a 2017, 28k miles. They wanted 30k for it. I looked under and it was a rust bucket. Insane. I realized all the CPO trucks here with low mileage are from up north. I guess they come to dealership at a good price. I was appalled at the thought of this much rust on a 3 year old truck.

Yup... I think the city should be paying me for vehicle depreciation with all the salt used on roads. Gm doesn't want their vehicles rust free, otherwise you wont buy a new one.

I like how every year they update the TSB about defective wax coating to include the current model year. Tells me they are real interested in fixing it. I really believe that wax coating is just to get it through manufacturing/assembly without rust. After you have it they dont care as long as you get passed the 6yr100k.

Yikes. My 17 with 43k miles has about 10% of that rust and I live in the rust belt.
