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 anyone that has the leak, decided to just deal with it for the time being, in the hopes that GM comes up with a better fix in time? I have a 2019 Sierra and just noticed the first sign of a leak today while hand washing my truck. I use a pressure washer and I’m not shy about using it around the spoiler. There was just a single small trail of water on the inside glass corner. Pretty minimal considering the pressure washer. I’ve never noticed any leaks during normal rain (and I check often). So I’m thinking I may just wait and see what develops from a fix perspective. I’m in Sacramento California so don’t get heavy rain anyway, plus the winter season is almost over.


I thought about waiting with mine too, small leak was just in two spots but wound up taking it in and letting them seal the top of the glass before it got worse and was needing a headliner, wet carpet etc. I pick it up on Monday and we’ll see if that was the right decision or not.

I’m doing that, basically. But not because I’m waiting GM out for a better solution. Mainly because my schedule isn’t that flexible, and I’m not in a hurry to keep going in this circus process GM puts us in with local dealers. 
 

I noticed mine leaking early November. Took it in and got it resealed late December. Leaking again early January, and then the headliner stain showed up for the first time. 
 

My carpet isn’t wet, the headliner is not staining any worse, and I have a towel against the window to keep the moisture from collecting. 
 

All that said, I’m not anxious trying to get this fixed. I figure the more time that goes by, the more the dealers will have an understanding of how to ACTUALLY fix this. 
 

This thread alone is proof of what I just mentioned. In early Nov when I posted my leak, I think there were 40-50 pages here after almost a YEAR of the thread being on here. 
 

In just 3 months, the thread has about tripled. Why? Because all us T1 owners are finally starting to see the leaks. So... a couple more weeks ain’t going to kill me to wait.

I’m in the exact same boat. I was at the dealer earlier this week for a separate electronic issue and the scratched the outside of my drivers door to the metal. I don’t really trust them to not make it any worse. That being said if I was closer to my warranty period being done I would be getting it fixed. 

 

Also so asked if they had seen many leaks and they said they hadn’t heard of any....

Do you have a picture of the model of the window they recently put in that leaked? E2 or E4? also be interested to know if the new window is leaking due to poor install or cracking in same spots.

What are these E2 and E-4 codes? And where to find them?

Yours looks like a solid window and not a slider.

No, mine is a slider and built in 9/19 and has the same code...

Nope it’s a slider.  No leaks yet.  I hope that e9 means it’s a newer design

oh wow. Now I'm wondering if all the spare E4's they are installing are no good. Again, we need someone to get GM on record with what the hell is going on here. not much consumer confidence.

Also, does anyone know where these go? They were left on the roof of my truck after the install.

 

Hoping its old hardware from the damaged window and that they were replaced lol

      Yes. You need to check out that thing, and the hub further.

      Would this be normal or a worn CV Shaft? 51K miles 3.5" lift? Boots are intact and no visible leaks showing. Attached is a the video I took. Thanks     https://youtu.be/ZnW7PPRmjJY?feature=shared

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.
