First time poster, long time lurker. I have a 10/2018 built T1 with the rear window leak issue. I have already opened a case with GM corporate and am scheduled to drop off the truck at the dealership tomorrow morning. In my case, the top of the window frame is cracked all the way through and is visible within the cab. I am concerned that the dealership is going to attempt to reseal the window and not replace the window. Any advice before I drop off the truck tomorrow? Based on this thread, I am anticipating that this will be a lengthy process before I have a resolution.

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 would just make sure to point out that full thickness crack and make very clear it needs to be a new window. I believe that is what the TSB mentions as well, that they need to inspect the frame and if cracked, replace.  Good luck, going to be a long ordeal unfortunately.

Just joined the club, not exactly what I wanted! 

 

Truck is a 2019 High Country with 1500 miles and purchased 30 days ago.  Build date is 8/18 with the passenger side leaking.  Truck is at dealership right now and was told they have ordered the sealant and will advise when it arrives.  Currently on the phone with Customer Care.

 

Amazed they can't just replace the window when there are visible cracks!  Sealant is a band aide fix for something that is BROKEN.  This is not a seal issue, it is a broken/defective part that needs to be replaced.  GM needs to own this and take better care of their customers.

The most fascinating part of your report is that your truck sat on a dealer's lot for 13 months. Wow. 

 

Sorry you had to "join the club".

 Update: Got my truck back today with the replaced rear window.

Problem 1 - Initially told it would be done by 3 yesterday so I said, "If it'll be done before 5 just give me a lift to work and pick me up when its done."  Then he said... well... it might not be done so we better get you a rental.  He called me at 3 yesterday and said it was done and that i could pick it up.  I said id drop off the rental and come right over.  15 minutes later he calls back to say its not actually done because the glue needs to dry overnight.

 

Problem 2 - I immediately noticed how filthy it was.  They didn't even make an effort to clean the rear window or surrounding area that was worked on.  It wasn't spotless going in but definitely came back filthy.  I looked down between the bed and cab and there was a huge strip of the old glue sitting on my exhaust waiting to fry.

 

Problem 3 - I could still see the messy caulk job on the top seam.  I figured with a whole new window, the glue would look perfect.

 

Problem 4 - There is a quarter inch gap between the spoiler and the glass on the left side.  About midway across it goes from a gap to line to line.  Spoiler is actually touching the glass above the slider and the right side.  Looks like the spoiler is jacked up.

 

Problem 5 - Below the glass there are scratches, presumably from a careless job cutting the old glue with a blade.  It almost looks as though they tried to hide it with touch up paint.

 

Problem 6 - Icing on the cake!  I opened one of the doors and heard a tink-tink sound come from between the bed and cab.  I assumed something was hanging in there.  When I looked I saw the left pressure equalizing vent contraption hanging out.  Its resting against the bed so when I open a door, it sucks it into place, making the first tink sound then falls back against the bed making the second sound.  They must have pressed too hard putting the rear seat padding back in and popped it out.  Of course you can't reach it to put it back in.  I got the service adviser and showed him.  He went to talk to the mechanic and came back and said there was no way they could have done that but that they'd fix it under warranty.  They need to order a new part he said.  I betting it would pop back in but they didn't even want to try.

 

I never noticed the defogging strips being so noticeable on my old window but I never paid much attention.  The giant vertical gold bands are kinda ugly.  Is this what the original one looked like?  

 

Overall, very disappointed in the workmanship on my new truck.  You would think for what I paid they'd take a little better care of it.  Not sure what to do from here...

#1 - Some sort of glue or something smudged all over the side

#2 - Notice how the gap is uneven, spoiler touching the glass on the right side but not the left.

Messy rear window smudge, still has suction cup marks

Tiny bit of a gap on the right but then the spoiler seems to dip down to the point where it touches the glass

Spoiler looks a little deformed just to the right of the slide, just above the glass

Funny, I noticed my spoiler looked a little off after the original seal, but I didn’t say anything as I figured I’m just really type A....and of course it leaked again 3 days later so I didn’t have to sit and look at it all day long worried about it.  What a mess, sorry we are all in the mess together.

Well so far my 2020 has been dry for 2 months. I feel all the new members pain. It really sucks and there is nothing they can do that will ever make it right other than a buyback. My 19 was in the shop so many days waiting for headliner and window that I could never get the smell of the shop out of my truck. I get in my 2020 and it smells fresh and new. The 10 speed is awesome too. I hope you all have luck like I did and manage to get gm to agree to a buy back.

I still check my window on the 2020 Everytime it rains waiting for that first drop. Although it's 12 degrees out so not much rain lately.

I am not sure which is worse the leaking Silverados or the freezing door locks on all the F150s. At least we can get in our leaky trucks, so there is that..

I have the solid rear window.  In the portions of this thread that I have read, this all seems to be pertinent to the rear sliding windows. 

 

Am I correct?  Or do owners with the solid rear window also have this problem?

Wow i tell you that state of GM dealer techs is a pretty sad site today imo. No more do you go to a dealer for quality work, you are more than likely to get a hacked together job from most gm dealers today then a local mom and pop auto shop it seems! I would go find another dealer Huntsman though chances are they are just all the same, sad that they give it back to you in that condition

I got a text message from my dealer that GM was looking into my issue with them on Monday. Today I got a phone call to bring it in so they can try to figure out what needs to be done and to pick up a Malibu to drive. I have Christmas with the in-laws this weekend and have to drive 3hrs away and really need the bed of my truck instead of my wife’s traverse so I’m  Going to take it in on Monday. Got a 5 day ski trip planned for Snowshoe WV on Jan 1st. I hope it’s fixed by then I’d really like to have r wheel drive and comfort for that drive if needed.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
