Paint delamination

[HyperX]

My brother in law has a 2013 Sierra Denali with this paint issue. Dealer in Kansas denied claim. said rust has to go all the way through. Has anyone seen this before? Car has never seen salt or anything else.

Story of my life.  I ended up having to rattle can the entire leading edge of my roof.  GM said it was wear and tear.

It's from stones hitting the leading edge of the windshield opening.  Thats wear & tear same as front of hood.

In my case, the leading edge of the roof was 3M'd.  The paint lifted off, stuck to the 3M and rusted underneath.

 

And meanwhile, my dad had the EXACTLY same issue happen on his 2010 Silverado but he managed to get GM to fix it under warranty.  They ended up stripping the front half of the roof and having it resprayed.  The service manager at our dealership admitted that a few years of the trucks had the roofs badly prepped for paint.

 

Keep in mind that a rock chip should just damage the location of the impact.  I know what those look like as I have plenty of them on my hood around the 3M, and even through the 3M.  A rock chip shouldn't cause entire patches of paint to lift off.

What the original dealer said - is that the cab was dipped in some chemical, and the line (production line) didn't wait long enough for it to dry. Apparently he has seen this in 2013s and GM is denying claims.

Based on my experiences, I've seen this in 2009 and 2010 trucks as well.

The process is completely automated and the body is dipped in a tank with bonderizer and is electrically  charged it is no a conveyor and then goes through an oven for approximately 20 minutes at  280F. The assembly line runs at a steady rate so the  waiting to dry is B.S.

I figured he was BSing my brother in law. In either case, it's pretty bad for a 2013. Arghh..
