May 6 2019 dropped off my 2019 Denali for rear windshield leak. They tried to pull and reseal, still leaked.

Ordered new rear windshield and it came in Friday May 10th.

Glassman supposed to install Monday afternoon May 12th.  It's Wednesday afternoon and truck still isnt ready.

Hoping for some good news tomorrow.

It's been 16 days without my truck!??

Well my 2019 early build leaker was replaced with 2020 hopefully not leaker. No signs of an leaks on the window or headliner of the 2020 so fingers crossed. Very impressed with the 10 speed after th

No leaker here so can't do a 100% verification, but the problem seems to be with the spoiler design, regardless of weather the sealer leaks or not, and any cracks in the trim make it worse.

Hope it's resolved for you. I waited 16 days total and mine got the whole window replaced and that fixed it.

That's exactly how bad mine was. I had both sides too.

Bingo. 

 

For those readers new to this thread, the rear window leak issue has almost exclusively been on trucks built on or before 10/2018.

So what has been the fix for those who’ve had theirs repaired? I took mine in on Wednesday and they ordered a new silicone recommended by GM per a bulletin that was sent out on this issue. Unfortunately, the new silicone did not correct the issue.

First step is to remove the rear spoiler and apply the sealant/caulk. Second step, I believe, is a complete new rear window unit.

A new rear window is the definitive solution.

 

Those windows are straight up defective and should be replaced. Adding extra sealant to a defective window is treating the symptom, not the cause IMHO. Unfortunately your dealer is likely to follow GM's TSB so just sit back, play the game and drive the loaner like you stole it.

 

But hey, what do I know...only took them three tries to fix mine...the third time being with a new window.

Picked mine up Tuesday. 3rd time was the charm. It’s rained a little here and there since I picked it up and it looks like the issue has been resolved. 26 days total in the shop. GM is also paying my care note for one month.

Supposedly there is a May 30th update to bulletin 18-NA-383 for the rear window leak repair. Does anyone have access to it to see what changed from previous versions?

If only this were as easy as wishing GM would replace the known defective A/C Condensers and Vacuum Pumps on our earlier K2's.

They would rather have two or 3 techs spend a day or more with tubes of silicone to repair rather than install a new rear window.

That is why I am curious what the new tsb says. Maybe they changed it to say replace window.

      Scan Tool Recommendation

      By CamGTP · Posted

      I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
