It doesn’t seem to matter where it was produced.  Mine leaked and it is US built.

Good to know, thanks!

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.

Noticed mine was leaking a little a couple weeks ago, so I dropped it off and they said it was fixed.  Well after washing my truck yesterday noticed the headliner was very wet on both sides of the truck, so obviously not fixed.  Large spots about the size of a plate on each side.  Any idea where the leak is coming from, is it the spoiler?

If you push up the headliner , I bet you can see some type of a crack in the corners. More than likely your in for a new window the next time you go in

I am on my 3rd window on my 2018. The slider leaks where it meets the stationary pane. I was recently told taking it thru a car wash could be the problem.  I said thats not an acceptable answer. Looks like they have had problems for years and still have. I'm going to keep going back until its fixed. Be leaking since it had 4000 miles on it

The 19s And 20s have a completely different problem ours do not leak at the slider it is coming from the top of the entire width of the window not just the slider... and my f150 would have a few drops in the cab from a high pressure car wash only.. nothing like what we are experiencing

It’s coming from the top of the back glass because for some reason the plastic frame develops hairline cracks and allows water in .. just got mine back yesterday

Interesting that the write up is specific to the sliding windows. I’m still curious on the solid windows and if GM even has a write up on it. So far good but I’m dreading the day I look up and see it wet.

I feel the exact same way my friend! One more leak and I’m taking a loss and going to RAM

I did go in my settings and shut off the automatic rear defroster feature.. maybe it gets the plastic hot causing it to crack. Just pure speculation of course

Really!! WTF

I would say it’s not anything like GMs problem. The 2019 rams did have an issue with leaking rear windows, and drain plugs not installed correctly for the panoramic sunroofs. But just from scouring all the ram forums the past couple weeks, the amount of complaints is nothing compared to this forum. They came out with a new window, which all the 2020s have and apparently it’s fixed the issue completely and honestly I haven’t seen one complaint for the 20’s

I really like my trail boss .. I can deal with a few minor issues but water leaking in my interior is where I draw the line.. if it leaks again I’m going 2020 rebel or 2020 F250

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
