Update on the rubber cord idea. The gap is not consistent all the way across and the rubber cord is firmer than I expected. I haven’t had a chance to try and soften the rubber up to get it to fit all the way across. Maybe someone else has some ideas on a softer weather stripping/ cord to fit in the gap???

I wonder if plumbers putty or silicone caulking would work?

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.

Update got the window sealed and it turned out Sh.t, big blobs on both sides. Dealer tried to cut it out, made it worse. They are ordering a new rear window and having it replaced at Safelite, hopefully they  do a better job. Rear seats and head liner have to removed, so excited to have a brand new truck tore apart again!

Totally feel you pain.  I am a 8/20 build too, so far my valve springs are good (1700 miles) but my rear window leaks as well, and my battery has had to be replaced.  

 

This is the exact reason I haven't had my local dealer attempt to fix this.  I really don't get why these windows all leak lol Its just so unacceptable  IMHO

I live in western Washington and it rains here a lot. I had a trans leak and when at the dealer I asked about this. He said they had never had one come in for that. He didn't even know about the problem.

Just rained in San Diego for the first time since April, or so I've been told since I moved here in December. Decided to take the opportunity to see if I had a leak. None so far, but will check again tomorrow since it'll be raining through tomorrow night.

Why would you think he's talking about a truck frame crack?
 
I'm fairly certain he was obvious with "a crack in the frame of the sliding window".
 
Maybe he should just replace the cam instead.[emoji1787][emoji1787]

Maybe some of us can actually comprehend what we read. This isn't the first time you've ran off in left field when the ball went right down the middle.

Took my 2020 to the dealer on Friday for the leak on the passenger side.  Its supposedly their first.  No cracks were found on the slider frame.  Having the headliner, spoiler removed to apply sealant.  Will see if it works.

Let's us know if you can where the dealer put sealant on the spoiler?  Straight across the top gap or around each bolt hole?

Leak is only at the window frame.  Spoiler has to come off to get to the window for sealant application.  I'll ask though on what they did exactly, hopefully tomorrow and let you know.

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.

Well I have been waiting a month for the replacement window to come in. I'm losing faith in GMC. I will let you know how it turns out. I have a bad feeling there will not be a happy ending to this story...

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
