Yeah this is their 3rd time cleaning it...I just need to get it in a good enough state to get rid of it at this point. The window is going to leak again...

You seriously need to find a different dealer to bring your truck to. No way in hell would I find that even close to acceptable!!!

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 hear you, this whole thing is a joke. I am disgusted with the dealer and GM. Brand new trucks are getting ruined by butterfingered mechanics and GM has no fix. I was told to take it one step at a time to get it fixed and that every vehicle is the different, when I brought up the history of this forum she dismissed it. Here we are with the same problems that everyone else has had without much help...

A new headliner for your truck is a must have, period. Sealing the entire gap between glass and cab should, in my mind, stop any water from finding a way in. Remember, you can bring your truck to ANY GM truck dealer. I have found a HUGE difference in service between dealers. Some are great. Some should not be allowed to go anywhere near a new vehicle. (I used to work at a dealership many years ago, saw it first hand even then.)

Yeah I know I was a Service manager at a dealership so I get it but GM is not much of a help either. I will regroup Monday with Customer Care. I'm trying to keep my cool because like I said this is ridiculous to even consider that seam sealer is the fix for this...GM should have had a good replacement window 2 years ago, this is unacceptable at this point.

Yesterday wasn't hard rain. 

I wash my truck every 2 weeks at a do it yourself carwash with high and low pressure water sprayers. I am looking for the leak after each carwash. Nothing so far. I'll keep everybody updated.

 

If I end up developing this problem, and GM tries screwing me like a prostitute desperate for a quick $20, then I'm going to move on. GM wanted to fuss about Ram taking their #2 spot last year. Looking at how they've handled things from 2007+ with V8 engines crapping out before 100k miles, cracked dashboards, and problematic 8-speed trans, they better start getting use to the view as 4th place. I'll switch to Ram or Toyota. This is GM's last shot in my household, and I get the impression a lot of people are feeling the same way. It's not enough for them to take care of me, but how they take care of everybody in general. If they're willing to screw everybody, then they're willing to screw me, too.

The problem for Gm is old farts like my father and I are dying off and taking our GM loyalty with us. He has a small construction company and owns about 20 Gm trucks. Never gets rid of any of them, the oldest is  an 88’ 3500 4x4 with 454. Still going! I have 5 myself. He just bought 2 new 3500 4x4 service body trucks yesterday. Gotta spend it or give it to the tax man!

These dealer horror stories are the reason I hesitate to have my dealer even touch it. I bought the truck used, and am still under the factory 3/36 warranty. Beyond the small leaks on either side of the track, the truck is pristine. I’m waiting on the needle tip glue gun I ordered, and warmer weather to fill the gap between the cab and glass. As a temporary solution I bought two different diameters of the Trim Lok cord. I’m going to try and push it into the gap all the way across the top of the window.

Do you find the gap between the spoiler and cab even across the whole length?   I find the gap is a bit wider on the passenger side.

If (when) my new truck leaks my plan is to fill the gap with 3m 5200. We use it in the marine trade to seal bolts and small holes under the waterline. It works really, really well. You can bolt an outboard to a boat, seal the bolts with 5200, take the bolts out and go for a ride. Strong stuff. And it comes in black.

Add me to the leak club. Sent me home in a Buick Enclave. They’ll have my 2020 Denali til next week. Calling in a window guy to fix it. So far in 2000 miles my truck has now been in the dealer twice. Got a check engine light at 700 miles and now this. Not to mention the Bluetooth turning my phone volume down with no known fix, thinking I should have gone with a Ram or F150. Always had GM but I don’t know anymore.

There is a know fix for the bluetooth volume on your phone - 

Go to settings on your phone. Go to sounds and haptics.  Then go to ringer and alerts. Turn OFF the "change with buttons" slider thing.

Problem solved.

Well thank you very much! Had no idea. Dealer had no idea. I’ll do it when I get it back, hopefully leak free.

I need to take a closer look at it. I bought the .25 and .38 closed cell cord. I’ll probably cut a short length of each and see which one fits the tightest, then do the whole thing. I have 25’ of each.

Got an Encore too. My wife's 2015 Camry drives better and it's an LE.
They had a window guy come in and replace a molding and said they didn't see any cracking. We will see next week after I soak the truck

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
