Today marks 1 year anniversary for me being without my truck for a rear window leak on my 2019 high country which caused my interior to be mold and mildew filled.  Since then i have been in 2 loaner truck and have now been in a rental truck since the weekend before memorial day.  Since march 17th gm district manager (who will go unnamed) until this process is over had ordered me a 2020 high country truck the weekend before memorial day saying they will escalate the process up,  then for me to find out through my dealer that my builder date for is was the week of August 20th,  my response back to the district manager was i dont want the truck,  give me a 21 high country.   Build date week of 10/5.  So today on my 1 year anniversary,   my dealerships website said my 21 high country  is now in transit.   So i might have it by Thanksgiving.  Oh ya forgot to mention that im still making payments on my 19 because i had a verbal buy back agreement with the district manager and because of covid the buyback division was not working.   And the last time i have spoken to the district manager was july 27th,  trying to reach him for 2 weeks straight vie calling and text with no response back.  When i receive my 21,  after the whole process is done  ceo mary barra will be receiving a very nice email from me saying how pathetic this has been

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.

I ended up getting the top gap 95% sealed and I sealed up the upper portion of the brake light. Took using multiple pieces/sizes of the rubber cord and a hair dryer to heat it up in some places. I eventually want to find a softer material that will seal it in one piece, but I tried what I could with what I have. Only had the truck for 2 weeks but after it’s first wash and our first rain there was a small leak on the passenger corner. My wife is heading up to see family this weekend and it’s supposed to rain all weekend. Truck will be left outside. This will be a good test to see if sealing the top gap and brake light gap stops the leak.

Does this leaking rear window issue seem to be primarily on crew cabs with sliders or are double cabs with sliders being problematic also? So far so good with mine. (fingers crossed)

I'd wager good money that it is cracked just like all the others in this thread. 

Welcome to the leakers club. 
 

I'm lucky, If you can call it that, I live in a dry place.  Such a shame that these vehicles are leaking.  Seems like such an avoidable problem.  You can watch the robots sealing seams and installing glass at the factory online.  Somehow there's a glitch in the assembly line that GM isn't addressing.  My $250 GMC that was my first vehicle had holes in the floor but was still water tight, unless you ran over a puddle.

I want to update and say mine is still not leaking, but I'm afraid I'll jinx myself.

 

So I will not say anything.

And it's pouring rain right now.

Picked up my truck after the dealer kept it over the weekend to let the adhesive dry.  My leak was only from the slider rail on the passenger side.  They applied a sealant to the outside of the window frame as part of the TSB from GM.  The vehicle had a very noticeable chemical smell in the cab from the sealant.  You can also see where they applied the sealant at the top of slider from the outside.  A bit sloppy in places but as long as you don't actually look carefully its not noticeable.  Also no sign of them removing the headliner or the spoiler.  Was worried it would be damaged or dirty.  

 

So far it's dry after melting snow and rain on the roof the past 3 days. Keeping my fingers crossed.

Anyone aware of any reports of 2021 trucks having the leaking window issue?

Nothing I’ve seen yet between here and Facebook. Way too soon to tell though.

Found some new evidence of water trails that weren’t there when I detailed the interior last month. I’ll monitor it, but if the headliner doesn’t get wet, I’m probably not gonna take it back. Don’t want to drive a crummy Malibu for a week while they make a mess again. A sad game of risk vs reward we play. Original caulk job held for around 14 months, FWIW.

      Trading 7.3 (Godzilla) for G.M.C gas

      It is a company truck. Not under warranty. Both companies I’m involved with usually buy trucks that are discounted when looking. Except what the owners drive. Being retired and minority owner. I don’t drive a company truck. If they have the new GM gas engine it would be in a service truck.

      2026 sierra bad brake controller

      By flattop · Posted

      Update!   Had the dealer look at the issue. First tech says no problem?? I said there was no voltage on the brake terminal on the 7 pin connector! He said he did not know what pin I was talking about. So they bring out a seasoned tech and I explain to him. He attaches a VOM and has me push the brake, and sees no voltage!!    Tom, the seasoned guy says lets go back to my service bay and look closer. We discover thru his on line system that the controller is a "smart controller" as it needs to detect a trailer connected before the brake voltage is allowed to the 7 pin connector!!! He also showed me a GM bulletin stating some trailers with LED lights have such low resistance the controller wont recognize them!!! I was thinking WTF, but thanked him for bringing me back into the service bay and explaining this all to me. He also plugged in a trailer simulator and it showed the brake controller was indeed working.   After my dealership visit I hooked up to an older camper with standard 1157 lights and the truck did connect and the electric brakes worked great!    Not to sure what I have to do with the equipment trailer with LED lights, I cant tow it with no brakes.   Why did something so simple for many years have to get so complicated!

      Do find out as that would be interesting if they have been using any L8T engines or for that matter have been running any of the Ford gas 7.3 to see how they have been panning out.    I assume your nephews engine replacement was on his dime as the regular warranty would have long past unless he had some form of extended warranty that covered such events. That shows though and may depend on the year of the build that failures are occurring with the valve train well beyond the warranty distance and more than likely so will others have that sneak up on them.

      I realize this is an old post and its probably been talked about since then on this forum and I may have mentioned it myself but the Chev multi flex tailgate on the HD trucks are all aluminum so there is that one item that I am aware of on a current GM HD truck that is aluminum but if its the standard tailgate then its still a steel unit as far as I am aware to current 2026 model year.

      Gas Prices

      By Chuck FB · Posted

      I am surprised it didn't pop back up some just in time for the end of school/summer holidays and July 4th time period. Here in Alberta it hit its low coming off the high back a week before the end of June or so and has been creeping back up some and would equate roughly to around 20 cents per gallon increase. Of course there are various factors and one is the games they typically play with wanting to capture that holiday vehicle movement but also our government directly causing our Canadian dollar to drop ( a polite way of explaining the real picture ) causing our prices to go up rather than continue down like it should have, and even though we are sitting on the crude.
