Hi folks, I have a 2000 GMC Sierra 1500 SLT. It’s beautiful & has many years of life left in her. I’m starting to see a tiny bit of rust/paint bubble in the rear wheel well & along the bottom of the door. What can I do to stop it before it becomes really noticeable?  Thanks

Unfortunately, those are extremely common places where rust forms on this body style. They generally rust from the inside out on the rear fenders, and rocker panels/cab corners. You can use a rust converter and paint over it, but you may eventually need to do some body work and weld in new rockers, cab corners and sections of bed side above the rear wheel wells. It’s not a big deal, it’s very common on these trucks and as long as you have a welder, you’ll be able to do the body work yourself.

Wow, you have a 19 year old truck and just starting to see a tiny bit of rust... Whatever your doing keep it up. I had a 2003 but the rocker rust got so bad I could stick my foot in it a few years back, now I drive a 2017.  Original owner and would have like to kept it a few more years for sure but once it starts it goes fast.   But I live in IL where the salt is absolutely horrible in the winter.

Yes, I know I’m lucky. I bought this truck from the wife of an old timer who passed away. This guy took immaculate care of it. It’s got 140,000 on it & I only do 6000-8000 a year. It’s got so much life left in it & I want to nip this rust in the bud. My brother has one same year & the rust is terrible. The wheel wells are all rusted & jagged. I don’t want to see that happen to mine. We’re in NJ so we get our share of salt.

If you remedy it and keep it clean it wont spread that bad.  I knocked out the rust bubbles in my rocker, powerwashed the rust flakes out and hit it sporadically with a wire brush and wheel.  I then sprayed a ton of black rust reformer into the cavity and its been pretty stable so far.   I make sure to powerwash the cavity every time i wash my truck to clean out the gunk.

 

my wheel well started bubbling and I tried the same but not so good results because the wheel arch has layered steel.

 

Your rockers are sturdy but since its a full frame truck its not critical from a collision standpoint.   

 

Use this opportunity to ensure the frame is clean and reform rust there as well!

      I purchased a brand new 2019 2500HD LTZ Iridescent Pearl,  2 weeks ago here in Oklahoma. The truck had 26 miles on the odometer. 3 days after I brought it  home, I gave it its first washing. I was so proud of this brand new truck until I ran into rust, on the lower part of the doors. I thought to myself I just purchased a brand new truck for $60,000, why in the world am I seeing rust. I immediately crawled under the truck to find multiple components that have significant/moderate red rust showing. The trans pan and rear disc brake covers are losing their plating with rust coming through.
       
      I immediately contacted the salesman asking to bring the truck back and trade for a different one, but......I was told financing already went through and they could not take it back. That was 3 days of ownership. It's been very painful and disappointing to this point, but I did get the truck into the Service Manager and he took pics and trying to see what GM is willing to do. I just came back to Chevrolet after years of Purchasing Ford products. I even have my 1949 5 Window that I drove in college.
       
      Has anybody seen this before on brand new GM trucks? See Pics

      So I've been trying to figure out what exactly this piece is called as on one side of my truck it's rusted really bad as I've attached pictures of both sides. It's some kind of bolted-on support beam or crossmember, but when I look those up online it doesn't pull up anything of the sort. I put some POR-15 on both of them (that's why they're glossy) but I'd probably be better off buying a new set. It's a 2006 GMC Sierra 4.3

      I purchased my 2014 Sierra 2 years ago with 20k miles on it and within a couple of months I noticed the paint bubbling of the side walls inside my bed. Took it to the dealership and it was under warranty so dealership played for it. Within 6 months the paint stared to bubble off the doors, took it back and warranty was expired so neither the dealership or GM would cover the paint. Paid over $1,000 to get the doors resprayed. Now he paint is bubbling and flaking off the portion of the bed that was not resprayed, the roof of my truck, and around the front windshield. I am starting to hear people complaining about the same issues. Anyone having this problem?

      A few months ago we started to notice something on our 2019 Silverado that no owner of a brand new vehicle wants to see. Rust. Specifically on our rear bumper, just around the plastic step. It wasn't huge and didn't spread very far from the edge... but we couldn't stop noticing it. There was no excuse for rust on a 8 month old vehicle with less than 10,000 miles. The photo above shows the minimal but noticeable rust patch. It was even happening on both sides and in the same place. The issue seemed odd. 
       
      Unfortunately, we've just been too busy to bring it by to our local dealership for them to look at. Lucky for us, our procrastination has paid off, because in the time between us first noticing the problem and getting off our lazy asses to drive to our dealer, GM has released a TSB about this very issue. 
       
      It appears that on most of the early trucks, production of the bumper was completed incorrectly. The steel assemblies should be bent into shape then chrome plated. But that didn't happen in a small part of the early bumpers. The supplier bent the area around the side step after the bumper was chromed. The new folds in the steel damaged the chrome, cracking it and making the truck susceptible to rusting. 
       
      What's the fix? If your bumper is rusting already, Chevy and GMC will replace it. If it has not yet started to rust, they will apply an automotive grade wax/sealant to prevent rust in the future. 
       
      If you're unsure if your 2019 has this issue we suggest doing the following:
      1. Give your truck a bath for heavens sake!
      2. Clean the rear bumper step area with a hose or pressure washer. Front and back! We find lots of dirt collects behind our step in the bumper assembly.
      3. Inspect around the foot step area and behind the foot step area. We found rust in both areas!
      4. If in doubt, wait for it to rust and kindly ask for a new rear bumper. 
       
      Our dealership, Banks Chevrolet in Concord, NH has been great getting our rust issue fixed. Our service adviser Justin has kept us in the loop during the repair and gave us a loaner Silverado LT while they have our truck. He even made sure any other outstanding service updates are also applied to our LTZ while it was in the shop. As it turned out, there were six open issues that needed addressed. 
       
      Here's the official Service Update you can print out and bring to your dealer when you take your Silverado or Sierra in for service.
