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 .

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..

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

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.

    • I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?
    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

    • I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.
