My 2014 Silverado has rust bubbling up in both rockers already

[Jcharley]

I bought my Silverado brand new and The rockers are rusting out already. I have 100060 miles on it and just noticed the bubbles in both rockers. Gmc has a corrosion warranty for 6 years or 100000 miles. I’m 60 miles over and I have to pay $1,800.00 out of my pocket for my percentage of the rocker replacement. I can’t believe Chevy still has the usual rust issues on the newer trucks. It is rusting out from the inside. I took a small screwdriver and pushed it through the paint and right through the rotted metal. I very disappointed that a $45,000.00 truck is rusting already.

No help for the current predicament but if you replace rockers, remove all of those plugs in the rockers , hose it out, let it dry, spray the snot out of the inside with fluid film, replace plugs.

The area around the rear wheels is probably next to go.

I’ve only owned chevys my whole life but the fact that they can’t design a truck with a big price tag not to rust is pathetic. I had to jump through a bunch of hoops just to get them to pay more than half of the bill but I don’t think it is enough. I keep my truck in the garage every night and take exceptional care of it. Is my truck a fluke or are all of the 2014-2018 silverados rusting as we speak?

That sucks! Any pics?

 

Moisture must have got inside. Are you missing any of the plugs on the backside? Penetration from step bars?

 

Do you live in the rust belt or area where they salt the roads?

 

How many miles were on truck when you took delivery? If truck had 100 miles on it at delivery and this was noted at dealership, then your warranty would be good to 100,100. My truck had 9 miles on it so salesman noted 9 miles at delivery.

 

That's how I understand it anyway.

It had 31 miles on it. (Great idea) I live 1 hour south of Chicago so they do salt the roads but I have a heated garage and keep it clean year round. I will take pics tomorrow and put them up for everybody to see.

So half the bill is 1800 bucks? So 3600 to replace rockers? Probably to late now but I definitely would have checked around with some independent body shops might have got it done for less than the 1/2 your paying. Also since you were literally 60 miles over it might be worth reaching out to GM corporate and seeing if they might offer some relief. I don’t have personal experience with this but I’ve read more than a few threads on here where guys have got this to work for them. Also does your dealer (assuming that’s who’s doing it) guarantee it for life? The dealer that has painted my passenger side one twice now does. Also there’s a pinned thread on here about frame rust on these trucks didn’t know if you have checked that one out and/or checked yours out? Only reason I mention it is because it might not be worth hanging onto that truck long term if the frame is going South. I’m currently looking for a replacement for my 01 HD do to  it’s structural rusted frame.

 

Thread about frame rust.

That's a bummer to hear.

The total bill is $7,000.00. The rocker panel is part of the whole cab. The fenders, doors,and bed have to come off. I have to take it to the dealers body shop to get it done. They do good work from what I hear but it’s a major repair. The owner showed me how they go about doing it and it will take over a week to do. Oh, and I called GM and they said I was lucky that my dealer got me 75% of the bill covered since I technically was out of warranty. I had to work late tonight so I’ll get pics tomorrow and post them.

My Chevy dealer was only gonna cover half of the bill at first. So I went there and caused a little ruckus and they came back with me only having to pay $1,800.00. (Too much if you ask me)

When your truck was new, did you use inner panel rustproofing inside those rockers?

[Jcharley]

No I didn’t use any kind of rust proofing.

Yikes! I know we don't like to use the F-word much around here, but if you're in an area where rust/salt is that big of an issue, an aluminum body might not be the worst thing.

Is it just in the cab corner or all Along the rockers?  The photos look like a cab corner which could be repaired for way less than $7000
