#188 of 208 2010 GMC Sierra 1500 undercarriage rust by a_user

Mar 14, 2013 (5:38 am)

Hi All! I bought my truck in California (orange county) in the summer of 2010. I recently moved to Florida, its only been 4 months, and have noticed that the undercarriage is developing rust on certain areas. THIS IS MY FIRST GM CAR AND MY LAST. This is totally unacceptable. I cannot believe the stories I am reading out here about other owners having the same issue. Even my hitch, which has never had anything attached to it, is developing rust!!!!!!
 
I have noticed something peeling off from the frame where the rust is forming. I've also noticed that rust tends to form on spots where there is rubbing on the frame; If a brake line or a harness rubs against the rame rust will start forming there.
 
I am very dissapointed with this issue.
 
Other than this, I love my truck.

This is an ongoing issue with so many trucks. I can not believe that GM and the NHTS can not offer help the the owners of these trucks. Please make sure you put in a formal complaint with GM and the NHTS ..... MAYBE if enough people do they will have to address this matter. You can look up my User name for all the info.
PLEASE ANYONE ON THIS FORUM WHO HAS A SIMILAR ISSUE...YOU MUST PUT IN A FORMAL COMPLAINT. THIS WILL BE THE ONLY WAY TO GET ACTION.

#191 of 208 lots of unexpected rust on frame by greensilverado

I have a 2002 silverado 1500 8' bed 4x4 4.8 v8. I bought the truck new at the end of 2001. this has been the best trouble free truck I have owned so far except the rust and rot. my rocker panels started rotting a few years ago from the inside out. when replacing them I was under the truck I noticed excessive rust like large chunks of flakes. on top of that i recently replaced my rear leaf spring shackles have both been replaced due to rot. I simply thought the rust was because the truck is over 10 years old and saw a lot of new england road salt. as I said before this has been a great dependable truck for the last 220,000 miles. I have done my best to protect the frame from further rotting by painting it with POR 15 rust protector. shame on GM.

Greetings all. I recently purchased a 2004 GMC Sierra 1500 and also noticed a LOT of rust underneath which has infected the frame and basically every part underneath. Shame on me for not looking closer before buying. I have two questions that are really simple to answer, but I am unsure what those answers are and am looking for help. This may have been discussed, but I want to perhaps bump these questions up in the thread again so that folks don't have to read through 191 replies -- most of which are just complaints instead of helpful suggestions.
 
Here's my questions:
 
1) I was told by a trusted friend who is a mechanic that my brake plates and shocks need to be replaced, and that would cost me an extra $1000 or so. My question is: What are the other parts in order of importance/safety concern that would be a good idea to either get checked out again or replaced altogether if this type of rusting continues to progress (which it will I am sure)?
 
2) What is the most cost effective way to prevent further rusting or help reverse the process before it gets any worse? The truck is already almost 10 years old, and not sure how long this has been going on.
 
3) How concerning is this issue on a scale from 1 - 10 (10 being worst)?

You state that the frame is rusted. Depending on the severity of the rust you will need to replace the frame which at that point you may want to junk the truck again depending on the severity as frame failure is usually catastrophic.

Sell that truck. It is defective. I had one just like it. Sandblasted the undercarriage repainted, replaced all brake lines, sensors, ABS etc. Rust got up in the instrument cluster, everywhere. Get rid of it, the rust will only progress. This doesn't happen in a normal truck.

Not exactly sure what this means or if dealership will do anything about it.
