2008-2013 1500 frames rusted through

Dusty734 · July 19, 2019

My 2013 Sierra-1500 has extensive rust between the fuel tank and inner frame rail. Probably 20 inch long area

Damn, how often do you do an under carriage wash? I take mine once a week anytime there is salt on the road.. How many miles on the truck?

My 2014 didn't look anything like that. Even my neighbor's 2009 Silverado didn't look like this and he only washes his truck a few times each winter. Mine had a little bit of surface rust where the lift picked the truck up a few times and damaged the wax coating.

I take it you never kept up maintenance on the frame coating? If you had sprayed it with oil or fluid film it wouldn't have done that.

Is there even any mention in the owners manuals of vehicles regarding how to care for/prevent this kind of stuff?

My '04 Sierra cab&chassis doesn't look anything like that, and I'm sure the truck hasn't been treated particularly nice (I wash it maybe 4-6 times a year), and p.o.'s probably didn't do much more, and I live in the snow belt and do a bunch of city driving year round. But lots of trucks around hear have fender lips rusted through, even relatively new trucks...

The body is in good shape ,a bit of paint flaking. GM offered me a $100 service voucher, as I missed warranty by 4 months and 400 miles .my 2008 is in much better shape than this .

Holy crap. Sorry you had this happen to you. Glad I got my truck rustproofed.

Dusty734 · July 19, 2019

This was washed twice a week inside frame as well. After 16 Gm products 8 of which were brand new, may be the last. The 2008 is in much better shape .

Don't blame ya, but don't think you'll not find this same issue on other brands..

Dusty734 · July 28, 2019

Dropped fuel tank, and welded a large patch in yesterday. Now to start cleaning and painting

I heard one of those youtube mechanics to avoid gm bankruptcy era trucks like the plague because they cheaped out on everything

Not true. The 07-2013 GM Trucks have been pretty good all around. Sure there are a few pattern issues, but what manufacturer doesn't have that?

Actually theres a GM recall on certain years and trucks. GM claims the antirust additives were never added to the frame steel. They are only offering to recoat the frame with a sealer. Cheap bastards are not footing to repair the frames that have rotted away.

No such recall. There is a TSB for under warranty frame wax repair, nothing more.
