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.

Has your new one been leak free?!

3 weeks on FUYAO E4 and leak free so far. However, I went 9 months and 13k miles on the FUYAO E2 before it started leaking.

Is everyone getting replacement glass? Has anyone had an explanation of the repair? My dealer is stating they will reuse the same glass. 

The TSB states to caulk the window first. If it re-leaks, replace the window. 

 

Not to give you a hard time, but we have a lot of new people coming to this thread and asking the same questions that are answered in it.

 

TLDR, I get it, but if you have this problem, it would behoove you to read the 1800 posts.

My dealership told me that GM engineering informed them that the rear window were a one time use.  If the caulking job didn't work they could not reuse the old window. This was after trying to caulk the window 3 times.

UGADawgs; I agree and understand completely what you are saying. I’ve read all the posts over the past several days as I had done all my homework and was planning to purchase a new truck this month. I was shocked to find this post and if GM is following this please be aware you should do something to resolve it.  But I’m still not aware of a consistent repair method resulting in a permanent fix for this issue. Yes, as many of you fine folks say that a “quality dealership”  that knows what they are doing can/will fix it but what is that fix? Sealant or new window + frame? I’m kind of in a bind as our local dealer has a horrible reputation, extremely limited supply of vehicles so I was planning to visit Everett GMC (based on positive comments I’ve read here) which is 7 hours away. So I can’t afford to run to Everett GMC with ongoing leaking issues. So unless I’m missing something the dealer repairs are hit and miss and even with a brand new 2020 there’s still no guarantee it won’t leak. That’s a $60,000+ gamble I can’t afford to take. Please tell me I’m wrong or missing something? Thanks in advance.

You got it 100%. If I were you, I'd hold off making a purchase until GM comes clean on what went wrong and what change they made with FUYAO E4 and/or what they are doing to fix this widespread issue. This isn't some bad power steering pump or infotainment system, issue. This is a leaking window causing collateral damage and multiple return trips to dealers with half baked fixes.

GM coming clean ain’t ever gonna happen. Design changes usually happen pretty quietly, and I wouldn’t expect anything different here apart from maybe an updated TSB. 
 

I had thought about doing some “destination truck buying“ like Everrett or Laura...but doing so would have made every problem with this truck a million times worse. Thankfully I bought local. And thus have somewhat of a leg to stand on in their service department after spending 6 figures at their dealer recently.


People underestimate the value of that when they only shop the cheapest price. I wonder how many bad experiences in this thread are attributed to service by a non-purchasing dealer. I know it’s not what GM wants, but one has to imagine if the dealer doesn’t view you as a potential future customer, they might be inclined to screw you around, not give a loaner, and / or do shoddier work.

My local dealer added some urethane to my rear window last Thursday and it’s rained for the last 3 days and I haven’t seen a leak yet. They did a really good job bc it doesn’t look like they touched anything inside or outside the truck. It was kept inside to cure before they gave it back to me. They also said they’ve seen quite a few of these so hopefully they’ve got the fix down by now and I won’t have any issues going forward. I’m just gonna assume it’s fixed and keep checking it when it rains. Fingers crossed I won’t have any more issues. Just for y’all’s information my window is E9 and it was built in Mexico in 4/19.

So I finally got my truck back from where they damaged a bunch of stuff when they replaced my headliner. They're still fighting me over the gouges on the passenger a pillar. In the process of fixing things, somehow they broke a piece on my rear passenger door... what the heck?

I feel your pain. When I got mine back after two months they didn't mount the roof console all the way, the sun visor was hanging off, C pillar trim scratched, and the seat belts on backwards.

Well add me to the leaking rear sliding window. Took it in to the dealer on Monday. He confirmed cracked frame on driver side corner of the frame. Ordered a replacement on Monday and it is supposed to arrive tomorrow. Service Advisor said bring truck in on Monday to have it installed.

 

I will post an update on how it goes and the window part number installed.

One month leak free with my replacement FayUO E4

Mine is an E4 and it's currently leaking, my appointment was set 2 weeks out which is Monday 3/9/2020. The dealership said it would take 3 days but didn't disclose what their fix would be other than they are sending it to a glass shop. Fingers crossed that I am not going down a path of constantly driving loaners and a leaky truck.

So I got in my truck this morning... and it's leaking again. The headliner is wet on the passenger side again. 
Was yours replaced or just caulked?

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
