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.

2019 RST Crew Cab sliding window leaking on both sides. Headliner is stained, the jack and seat brackets are rusted. The dealer performed the TSB farmer fix with seam sealer yesterday, I will pick it up tonight to see the damage... I am looking to trade it for a solid window 2021. There is no way that I can keep this truck without a true fix...

 

I called GM 20 times until I talked to someone but it was no help, to get out of the vehicle even though this is a known issue without a fix, I am on my own is what they told me. I am absolutely disgusted with this whole deal.

All, I have followed this forum over the years whenever issues came up.  Had two 2017's with nothing but issues and up until last week, no major issues with my 2020 at4.  That is when I noticed old water trails on the inside of my rear glass.  Straight to the carwash to verify, and sure enough I have 6 or so cracks in the window frame and its obviously leaking.

 

In my line of work, I have a client that owns a local glass repair company.  I gave him a call to check the aftermarket for a replacement window, because I do not want to deal with my dealership for many of the reasons listed in this forum.  He actually found an aftermarket electric slider available for our trucks.  It is a non Fuyao make.  They have ordered it and will inspect it, then advise me on the best course. 

 

Just wanted to give everyone here a heads up that there is an aftermarket option.  Yet to see if it is a better option, but its an option, nonetheless.  I will most likely go with aftermarket glass and pay them to repair, rather than screw around with my local service department, which sucks, at best.

Definitely keep us updated!  I am willing to pay out of pocket for aftermarket instead of dealing with a faulty dealer part time and again.

From what I’m being told it’s about $425 for the aftermarket solid with defrost to $525 for a factory solid GM window installed. Sounds like cheap insurance. The aftermarket slider is a thought but probably coming down the same line.

Thanks for the info Blue. Mine is going in tomorrow for them to try and seal the window. My dealer uses an outside glass specialist and he has apparently done a bunch of these so far, so we'll see. I'm giving them 1 shot at fixing it. Once it leaks again I am going to go the solid window route.

Same here. Had to make an appointment because my dealer calls in an outside vendor who has done these. We shall see......

Any information from your local glass repair company on the Manufacturer and Model # of the aftermarket electric rear slider that they ordered???  I am in possession of a new GM 84944319 but have been hesitating to have it installed if it will not solve the leak problems I have experienced with the previous OEM slider.

Called a local non chain place and they want $675 to install a solid window. Same price regardless of brand.

I spoke with him this afternoon and the new glass was delivered to them today.  He did not go over part numbers, but did mention the manufacturer was ATI.  I believe they produce OEM for Chrysler etc. and aftermarket.  So it is indeed different than the OEM GM glass.  They are bringing in their tech managers to all put their heads together.  He said I had evidently opened a can of worms, some of their techs are brought in by dealers, some of them do no work for dealers.  Several techs in rural areas were well aware of the issue and have worked on dozens for GM dealers.

 

The company owners now are considering not touching any sliding windows unless under contract from GM.  They don't want the liability to fall on them if someone comes directly to them, bc if the truck is less than 3 years old, they order OEM glass, which we all know will just crack and leak eventually.

 

Anyhow, they are going to study the aftermarket slider and compare it to several OE GM rear sliders and advise me after they have done so.

Probably 25% no leak, 75% for leak.

Unfortunately, since I learned of this issue all of 3 days ago, I have reached out to 4 of my buddies and my father who all have 2019+ trucks with sliders.  All of them, except my dad, have leaks that they were not aware of until I explained this issue.  Been driving around leaking water unknown for months and years, just as I have been.

I agree with the post above.  I think many people are driving around without any clue there's a leak happening.  Especially if the headliner is not showing any signs of water.

 

I wouldn't have known to look for a leak if it wasn't for this forum/thread.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
