Whelp, add me to the list. First rain in a long time over here in the Seattle area and what do you know, the rear slider has a small leak onto the lip behind the seat. Appears to be a small leak, didn’t soak the cushion, but I can feel that it seems to be seeping from the slider track on the passenger side. Truck is a 2020 with 32k. Dealer set me up for next Friday and promised to get it taken care of. 

 

Wanted to update after some further investigation: while there is a streak down the passenger side of the rear window, suggesting it is coming from the top, there is also a crack right above the slider portion. It looks like it goes all the way through. Interestingly, there is no water coming from that spot. I hope the cracked frame is enough for the dealer to replace the window rather than attempt to use sealant. 

 

Update to the update: Dealer now taking truck in Wednesday. Because of the crack in the frame, they will not be attempting the standard repair, rather going straight for a replacement. I sure hope there is a newer model window that solves this problem!

 

Ok, repair update: Truck is back, was less than a 1 day turn around. They even had a loaner Sierra for me! The advisor said they keep a couple window units around for this repair and have been doing them every so often. Glass install looks good. Hope it solves my problem!

What I saw with mine. The crack was near the center but the window track acted like a gutter and took the water to the far right side of the window and it went down the glass from there.

Update on my 2020. They sealed it in the spring and it seemed ok -but noticed it leaking again last month. Took it in last Thursday and they are putting in a new rear window today.

Update on my leak: rear glass replaced, then I went ahead and sealed the top of the glass using the product and following the sticky in this subforum. When I removed the roof spoiler I found that there were only x2 foam seals and nothing else (spoiler had clearly been off at some point), it didn't seem to show any signs of leakage up there, however. The next day there was heavy rain and I let the truck sit out there for a few hours, no leak as of yet. Hope this solved it for good!

The dealer had tried to seal the rear window leak in the spring and this fall it started leaking again. Last week they installed a new rear window and the tech notes indicated that the original window frame has significant cracking.

We have had some significant rain and everything is dry, so hopefully the problem is solved -thank goodness for warranty!

Nice! I took no chances and removed the headliner/spoiler and did the external sealing after my new glass was installed. I do not want to deal with this over the winter.

2020 Crew built in Silao, 9/20....    2,135 miles as of today.

 

I have drips on both the left and right inside of the window. There's a rail at the top that ends about 2" before each side and it appears it's coming down from there.

Not sure if I should try to warranty or seal it myself.

 

 

 

I started another thread detailing some warranty issues including this window leak from last month. They applied seam sealer to mine but I didn't have any cracks, just leaks from the top. Honestly they did a crappy job. But it doesn't appear to be leaking anymore.

2020 Silverado with sliding rear window. Bought used 2 weeks ago with 19k miles. Day after leaving dealership the headliner was soaked and water pouring in during heavy rain. Dealer had it for a week. Did the TSB and so far has fixed the leak but with the way they gobbed sealant on the top of the window I can’t see how it won’t leak again…

That's not good news. I'll probably end up doing the @Leevon solution preventatively to my '23.

2019 I bought new. Just noticed the leak on passenger side back window. I can now see a slight water stain on headliner so its been doing it a while unnoticed. I can now see water trickle in after car wash. Made repair appt with dealer. 

They wouldnt say its covered until they look at it but I cant imagine its not. I still have to pay to have the topper taken off, stored then reinstalled. First time in my life a vehicle has leaked from the roof! Not unexpected thought given this post right from the beginning.

Both my 19 had the leak and just got my 21 Silverado's rear window leak fixed.  My guys @ the dealership got me fixed right up but such a pain to have to take it in for that.

What's the best way to check and see if there is a leak? I've never noticed any wetness in the rear, but my truck smells like mildew, or something, lately.

Add me to the list.  2019. Started leaking bad recently.  Dealer charged $700 to repair.  Not covered by extended warranty.

I had a Sierra a little while back and was having issues left and right. Contacted California Lemon law Center to see if something could be done about it; they were able to get all my payments back and even some on top. Would highly recommend any of you who are experiencing issues with your cars to reach out and see if you have a case.

 

Here’s their website: https://californialemonlawcenter.com/

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
