Just an update on this situation, haven't drove my Yukon for a couple of weeks now, it sat in my heated garage the entire time. Decided to take a look underneath to see how it looked, and to my unpleasant surprise, the rust has spread & is worsening. Not really surprised thou, but it most definitely hasn't gotten any better.

Also, again not surprised, the dealership has not paid me yet, so apparently I will have to file more legal papers which will cost me more time and $$ in order to get what'* owed. Can't imagine a dealership not taking ownership of the damage they caused...

And my headlight leaking issue has not gotten any better either, and yes, this is all completely on the inside of the light.

You don't have many options here. Other than the route you have already sought with getting compensation back for the faulty undercoating. There is nothing more you can do with that battle. GM and its dealers are well funded by thousands of lawyers. They will never settle, but would rather push everything to the last minute hoping you would just give up. And this is a prime case of it.

As far as the frame goes. There is no such thing as a perfect undercoating. Especially when everything is assembled. You have 2 options here. 1. Strip it down to the bare frame, sand blast it, dip it, then re-coat it. 2. Buy another frame brand new, coat it, then transfer everything over. And even then, I can pretty much guarantee you that it will start to rust from the inside. Undercoating doesn't prevent rust. It just hides it.

Well, I don't plan on giving up anytime soon. I'll continue to file complaint with GM on a daily basis until I find a lawyer who is capable of handling this type of case. I know there is no "perfect" frame out there, unless you buy a high-end exotic car there are some, but I still don't accept or believe a frame should look the way mine does when it was a year old. When you look at my '05 GMC frame, it still looks almost as good as the day I bought it. So it is possible to do a better, more thorough job. And I agree on my options, however that needs to be covered under GM warranty. I never thought the frame would get replaced, but I surely thought the specs for doing it would have called for sanding it down or sandblasting of some sort. Not just the cheap rattle can stuff anyone can buy and do themselves. GM needs to be held accountable for their products and how their dealerships are being operated. So far I have 3 dealerships all performing substandard work or not being able to do the work at all. I've been dealing with a nightmare of issues on my wife'* '16 CTS. It was in the shop for over a month. Before I picked it up, I asked many times if the problems were fixed. Within 5 minutes of driving it was doing several of the same things. I got them on video and sent them to the dealership and they did nothing. The GM of the dealership doesn't even want to fix the car, rather find me a different one so they don't have to fix mine. So I have been waiting 5 months now and still have nothing but problems and now it'* leaking oil. So GM need to get their act together and take care of the people who've supported and continue to support their brand to this day. It'* total B.*. and if I treated my customers that way, I wouldn't have a business anymore. So I'll keep on fighting until something of some type of reasonable resolve is determined.

How does my '13 year old frame look like-new yet? Because it was done properly and with quality materials. So it is possible to have a much better quality frame than what I'm dealing with currently. I know GM has thousands of lawyers, and I wish others would come forward as I'm sure this could have the makings of a class-action suit. I expect better, for what this vehicle costs new, it should be much better than it is.


13 years old and near perfect condition

Things were made differently 13 years ago. Different steel, chemicals blah blah blah. I could go on.

Yea this is very true, price goes way up and quality and support drop down to unacceptable levels. And the manufacturer doesn't care. It'* no wonder GM has so many legal/financial troubles. Maybe one day they'll get a clue and figure out how to fix their mistakes and take care of the people who support their brands for decades.

My 2001 YukonXL spent ~165,000 miles in Northeastern Ohio and Pensylvania, then came out so I'd have the chance to take pity on it in Colorado at ~183,000 miles. Now at ~295,000 miles it still has way less rust than yours. Not intending to brag.

I agree with statements of "different materials/methods/etc." above, but also submit that this doesn't make it right. If they had the art of rust-resisting frames working well then they likely wouldn't change what they do except to (1) make it even bettererer or (2) save money/maximize profits/etc. or (3) they have some amount of lack of control of internal processes/manufacturers/suppliers/etc. or (4) the job of rust-proofing wasn't completed correctly during assembly.

For (1) it didn't work, they should repair

For (2) okay they saved money on a bazillion of these cars and few noticed so eating the repair costs should be negligible, they should repair

For (3) shucks that'* too bad . . . and they don't market a discounted "Yukon Lack of Control of Internal Processes/Manufacturers/Suppliers/Etc. Edition" or Yukon LoCoIPMSE , probably because the lettering would eat all of the savings, even as an acronym. Either way the point here is: They sold you a car while emphasizing quality and reputation. It'* up to them to get something so basic done correctly. They should repair

For (4) darn, well that'* one thing that warranty is for, and if too many come back during a particular shift/day of week/etc. then they have computers that can figure that out and allow GM to fix the issue if they so choose. They should repair.

No, I hear ya and that is EXACTLY how it should be!! My '02 Camry with 170K looks almost as good as the day it was purchased. No rust whatsoever and it'* been driven hard during cold/snow conditions. We have snow almost 6 months of the year too. There is no excuse for this rust and the ****-poor job that was done under OEM warranty. GM failing to do something about this frame issue or the negligence on behalf of the "Cadillac" dealership is absolute B.*.

My simple resolve to GM is to simply find me a newer Yukon with similar or less miles and buy me out. I'd be willing to pay extra for a model year newer or something close. They continually ignore me day after day. I'm not giving up, I will keep at it for as long as it takes.

Appreciate your response and input!
