Rust on 2014 Silverado?

Phil0922 · January 3, 2017

I've seen many threads, but still not helping.

2014 Silverado Z71. Seems to have a some rust underneath, is it too much? Should I address this? Currently live in FL, truck came from up north (There for a year).

Pictures are attached. Can provide more as these aren't the only areas. Thanks for any assistance.

Not advanced yet. That's how a rust belt State vehicle will look if a wet/iced salted vehicle is parked in a heated garage instead of leaving it outside in the cold, or the salt residue is not flushed from the frame with water ASAP. The newer models have plastic coated brake lines which should hold off corrosion, but you have to make sure the salt is removed from the steel gas tank vent and supply lines which will rust badly.

Other than stripping the frame, best bet is to scrape and coat the areas with rust restorer compound, and undercoat.

From up north that's probably par for the course but it is worrisome if you're not used to seeing it. I'd be worried if the body had any rust though. I once had a new 2000 F150 whose door panels start rusting out in earnest after the first 15 months. Also, it had thousands of teensy brown rust spots on the hood and top of the cab in the same time frame. Easy to spot on a white truck. I ended up taking sandpaper to the rust under the doors and spraying with white Rust Oleum the day before I traded it off for a 2003 Ranger FX4 and it looked almost new again! Had the Ranger until last year and the body never rusted anywhere. But underneath was a rusty nasty mess. I blame most of that mess underneath on the road conditions at a steel mill where I work moreso than the salt on city streets and roads.

Fluid film is a great lanolin based protectant that you can spray the undercarriage of your vehicle with, keeps it from rusting and keeps the metal protected in like new, does not seal and rest and water like undercoating does. All natural and keeps the underside like new

OK, so the truck was returned. Loved it and loved the price (although I know why it was priced that low). Bunch of headaches in the past couple days.

Purchased at Autonation Chevy in Clw, FL. One of the most stressful car buying experiences I've had in a while. I wanted to talk to the sales manager to see what other options we had and he never showed. Some young sales kid came running out to me to give me the key and registration to my traded car just to push me out of the lot, I was about 1/4 mile from the building. took the car home furious. Went to a GMC dealer around the corner a couple days later and picked up a 2014 DC, LTZ 4x4 for a little more. Much happier now. No rust.

I should've looked all the way underneath, I know. It was a stupid mistake that luckily didn't have any harsh consequences. Being in FL i'm not used to rust like that unless it's been dunked in salt water. One good thing Autonation had was a "no questions asked return policy for 3 days". The thing that pissed me off more than anything is they claimed to have a 172 point inspection. When asked about the rust, they didn't have an answer. All is well now. thank you for all the help guys.

The 2014 trucks had some issues with the wax coating on the frame not being applied correctly, that truck looks like it was one of the affected trucks.

GM uses a piss poor wax coating on the underside of the trucks. Looks normal for something that has been driven in the snow and salt for 2 years.

HondaHawkGT · January 7, 2017

Well it's not Toyota-magnitude yet. You have options to fix it. You could:

-Spray the rusty areas with oil/Fluid Film (don't forget inside of boxed frame

-Removed as much of the black wax as possible and apply either POR-15 or Chassis Saver to any rusty or exposed steel.

-Try to reapply the shifty GMwax to areas that flaked off.

I used the first option as of now.

Do not waste your time/money on the rubberized undercoating products.

Traded it back and purchased something newer. I still live in FL near the water, so if anything like this happens to the new truck, I'll note this. Thanks for the info!

Based on the Carfax, this was only in New York (Snow) for 1 year. Then it came down to FL. The fact that it did this in 1 year irks me. Previous driver must not have taken care of it. I swapped it for something newer/better anyways. Thanks for the info!

Back in 2015, you could go to a Chevy lot and see brand new trucks with frame rust already. And not just one or two, multiple. It is not the previous owners fault this time. I know this from actually going adn looking at the lot after noticing it on my old 14 Silverado just a week after having it. I wasn't happy, hence why I now have a 2015 Sierra.

Yes, my 2014 has rust too. GM does have a TSB out on this, which they refer to as "cosmetic" issues. I took mine in for that and they did a hack job on it, just touching up the rust, which has since returned.

GM quality is truly terrible.

Here's my old 2010 after 3 years, 40k miles, also from NY. Seems hit or miss. I had the rocker panels done at 65k and by 75k my rear wheel wells were rusting through. Truck seemed doomed from day 1. My frame was redone by the dealership at 40k, but only lasted a year. (And they did an awful job)

Hopefully my '15 fares better.

crushNchowda · January 13, 2017

It may look ugly, but in reality thats just steel reacting to the conditions, The layer of rust is an oxide & won't deepen immediately it takes ALOT of abuse over longer time to get through something the gauge of frame steel. If you were to blast that steel, hit it w/ a wire brush rotary, brillo, etc. & some oxiclean then hit it w/ a mist of oil followed by spray can clear coat it'd be mint for a long time.

HondaHawkGT · January 13, 2017

Mine is on the verge of turning 3 and 97% of factory wax is still in place. The only place where wax is missing is at the underside of the frame where a lift contacted the frame for a dealer service visit last month. Sprayed/brushed with fluid film twice each year, lightly rinsed a couple times every winter.
