Hey everyone, Just saw this thread and went to look at my window and I'm also a winner of the leaky rear window! Anyone who live in Socal have a dealer they taken it to that have knowledge of fixing this problem? I have a 2021 GMC Sierra and I can't believe that this been going on for 2yr and GM haven't addressed this problem.

Tustin knows of the issues and goes through the steps one by one.
Hardin said they never heard of leaking windows

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 use Courtesy Chevrolet in San Diego. Katrina is my service writer. She's familiar with the leaking rear window problem. They have handled several of them already.

Were they able to fix it correctly?  Or you had to go back several time?

I live close to Long Beach GMC I'll take it there and see if they can correct right the first time but I was hoping someone on here had good experience with a dealer already.

I haven't had a leaky window, yet. Every time my truck has gone in for service (accessory install, 7500 mile service) I've asked them to check for a leaking rear window. Nothing so far. I also check after my carwash every 2 weeks, and after rainstorms (like today's) and I don't have this problem yet. With that said, I'm satisfied with the type of service I received from Katrina. When a 2 hour install job ended up taking almost a week she kept me in the loop and even provided a loaner. Really good customer service so far.

You're almost 2 hours from me. I doubt you'd want to travel all the way down to San Diego when you have a dozen other dealerships that are closer.

Did you know what they did to your truck to stop the leak? Remove and replace the window or just reseal?

Never knew about this issue when I purchased my 2020 Silverado......

I kind of wanted a sliding rear window when purchasing but my pick of the lot RST did not have it included. 

Seeing this, I'm pretty happy I purchased one with the solid window.

Dropped of this morning for round 2 at Tustin GMC. Service tech said that this time they will replace frame and he think that also includes the glass. This will be done by a 3rd party glass company. Hopefully this does the trick. Bummed that I will need to get my rear glass tinted again. Going to try and get GMC to cover the cost or at least float me some GM point instead. Got me an Acadia SLE as my loaner this time.

Did you not have factory tinted rear windows? Or did you just want it darker. I would think if you didn't have factory tinted you could get them to put one in.

I had all my windows IR Ceramic tinted after I bought the truck. If they replace the back glass, I will have to get it tinted again out of pocket for me unless I can get GM to cover the cost.

Just got my truck back. They replaced the entire rear window. Tech found 12 inches of sealant not applied from the factory. How I didn’t have a rainforest waterfall I have no idea. Supposed to rain tomorrow. I’m gonna park it in the driveway and see what happens.

Again, I haven't had a leaky window, yet. I'll let you know what happens when my turn comes around.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
