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..

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
