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

I appears you paid for something they didn't do. There should be some trace of the protectant somewhere. I'm not seeing it.

People are still driving trucks built in the 1990s (me) more holes than swiss cheese and the frame hasn't cracked otherwise broken yet.

What he said ^^^   Not sure about the US, but in parts of Canada they use a thick tar like substance to undercoat with when you buy that option at the dealer. None of that is present in your pics. I

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?

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.

      Joke Thread

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
