Could you request the rear window without the slider instead?  Just curious 

Probably not since it is part of a package. One that is usually ordered as a standard option on dealer stock high end models.

Are you able to opt out for a non sliding window replacement as a fix?

 

It would be cool if they switch to the tundra style window. The entire window gose down. And it's not like they have to design something new. Just pull the 1984 caprice station wagon designs from the archive. Copy, past the rear window design and boom problem is solved.

That was my thinking, if I get the leak issue I wondered if you could ask for the solid non slider for a replacement.

The dealer will not just replace the rear window just because you ask them to. They have to follow GM's orders which are to use the sealant. Some have replaced the slider with a non slider, but they have paid for it out of pocket. As I stated earlier, if the tech knows what they are doing it only takes one trip to the dealer for them to lay a bead of sealant across the top of the rear glass. My dealer's service dept/tech had my truck ready the day I dropped it off. He said he removed rear cab spoiler to access top of rear glass, laid the sealant, and reinstalled spoiler. Left it to dry, and I picked it up that afternoon. Takes about a 24 hours for it to fully cure.

 

My tech said he has done so many that he can not count them, but has not had one to come back for a leak that he has sealed. I told him about how many folks on this forum has had problems with their service departments and having to return multiple times for the leak. He said he can not understand why, because the sealant is a good fix and has worked well for them. They have not replaced any rear glass sliders at all, just sealed them.

I do think that not all techs are created equal. The sealant job on my truck for the leak was probably an 8/10, from how I looked at it. It held the seal for about 3-4 months, then started to leak again. 


So... I DO think a tech that can lay the bead well gives owners a longer horizon to go without leaking, but I also think it's not the permanent fix.

Unless it is liquid nails or window glue, caulk and other sealants will shrink and crack over time and lose their efficacy, which means the leaks will come back.

I've posted it so many times. People say that the dealer should follow the TSB. However it's like you said not all techs are equal. Just like everyone of us on this forum. I could give the TSB to 100 techs and I guaranty you will not get the same 100 results!

15 months later, my seal job is still holding. The Kent 10200 sealant is a pretty stout product, and I believe if applied correctly it can last. I would say it’s permanent in my terms, mainly because I’m trading next year and I don’t care what happens after then.


The guys who want 10 years out of a truck might have more of a reason to pucker up.

Any good sealant should pretty much fix the leak for the life of the truck as long as it’s applied properly. RDI HVAC silicone sealant I use for work holds up on outdoor and rooftop units sealing different material types together for 15-20+ years being exposed to sunlight and all elements. $5 a tube, -60f to 400f service temp, 25% joint movement. 
95% of contractors cannot lay a decent bead of caulk. I do not think this average is much different than dealer service techs. I agree the fix not holding is most likely tech error.

And most likely the majority of those errors are improper surface prep.

I'm puckering... I try to keep cars 10-15 years. Maybe I should just use spray foam - lol

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      OCI, not when but why?

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.

      Engine Wear and ISO 4406   1.) Cold Starts. 2.) High Particle Count. 3.) Low operating temperature viscosity and high low temperature cranking viscosity. 4.) Depleted AW, Friction and Acid packages.  5.) High engine load.    https://me.caltexlubricants.com/en_me/home/learning/from-chevron/heavy-duty-diesel-vehicles-and-equipment/The-Importance-of-Clean-Engine-Oil-and-Its-Impact-on-Equipment-and-Business-Performance.html   High particle counts have five sources. 1.) They are manufactured within the engine. Both wear debris and amalgamation of degradation products and combustion driven soot (worse in GDI). 2.) They are ingested via intake air. Ever hear the best oil filter is a good air filter? 3.) They are entrained in the fuel. 4.) This one is insidious. They are introduced in 'fresh oil'. 5.) They are introduced during the oil change.   ISO 4406 is the test that measures and quantifies the combine effects of all of the above particle related issues. You can mitigate your way into multiples of engine life by being attentive to them all.    https://www.hyprofiltration.com/blog/is-new-oil-clean   (from the link above)    [Quote] What Is the Recommended ISO 4406 Cleanliness Code for New Oil?   A good upper limit for new oil cleanliness is 16/14/11 (ISO 4406). Typical new oil usually has ISO codes of 19/17/15 or worse, which is far too dirty for sensitive components. This can be a major cause of degradation and premature failure.
