I'm sorry to hear you guys are waiting this long to get a headliner or rear window replaced.  Not acceptable at all.

 

Just wanted to follow up on my bolt left behind after my window sealant work.  Seems like it wasn't an 1 1/2", but the length of a Canadian quarter.  Similar size to a US quarter.  I'm hoping it is a bolt that belongs to anywhere but the ones holding up the spoiler from inside/underneath the headliner.  If any of you guys have any idea, please let me know.

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.

My .02

 

Forget about a hairline crack in the window frame.......the crack was SOP for the removable Avalanche rear window where the glass expanded from heat faster than the plastic frame surround and cracks developed in the frame.........but they never leaked water. It's all those holes punched in the roof metal directly above the headliner area that scares the crap out of me. I've seen this before on Camaro trunk mounted spoilers, Chrysler trunk mounted luggage racks and outer fender wells where gasketed screws are used to prevent leakage. Once removed they need new gasketed screws. That's why absent leakage my spoiler can pop all wants in the hot Sun.....no way I'm taking it in for a dealer removal and reinstall.

 

Currently mine is dry as bone after 4K miles and 6+ months of hand carwashes,  mountain thunderstorms, high speed runs in the rain, and 2 days of 6 in. of melting snow on the roof. My .02 experience with the Salio snot used on the seals of my Avalanche submarine was to keep it away from any hands free carwash that blasts a narrow stream of 300 mph air across the roof and blows out the crap spoiler gasket and sealant (if any) in the holes into the interior...I won't even spray a hose directly into the narrow gasket area separating the spoiler from the Silverado body let alone blasting with a pressure washer or forced in by 300 mph air......and once these seals are compromised they continue to leak.

 

And the dealer can goop up or replace the frame or spoiler gasket as directed in a TSB, but unless the seals for all entry holes to the roof are addressed it may still continue to leak or blow out the next time it is compromised under pressure.

I guess I'm shit out of luck then when it comes to washing the damn thing.  I have neither the time nor inclination to hand wash my truck.  It's car washing (brushed or brushless) only for me.  For now, my sealant TSB patch job is holding.  I usually run it through a wash about twice a month weather permitting.

I’m not sure that’s all there is to it. But at any rate, it’s a defective design, no need to cop them out on it or go through special procedures to avoid something that should never happen anyway.
 

Earth to GM, you cannot produce a full-sized truck that needs to be hand-washed. Know your market. Fleet buyers do not hand wash. Construction workers do not hand wash. Most people I know buying for personal use don’t either, especially not when the garden hose is frozen 6 months out of the year.

I hand washed only for 5 months.  Daily driver.  Summer and fall.  Nothing strenuous.  Still leaked like a sieve.  So don’t think for one second that hand washing will save everyone from a faulty design. 
 

im still shocked I was told they haven’t changed anything in the design process to fix this mess.  What a disaster.

Oh boy.

 

Always fun to see what you should have known before buying.  Guess I'll deal with it when it comes up.

I’m not gonna have XM for first time in 19 years because they want to force me to buy $1420 option package that includes a leaking rear window

Welp, add me to the list. Thought mine was good but checked this morning after rain last night and passenger side is leaking in two places. Doesn't seem as bad as a lot of them on here.

 

Question, to do the "caulking" procedure, do they have to drop the headliner? Not thrilled about having my brand new truck disassembled. Has anyone had luck with this method without having the window replaced? I recall a few but lot's to read through. 

 

Second question - has anybody tried to fix themselves? Hearing the horror stories, I figured I'm not shy of trying to seal the window myself first. I know a lot of you will say don't do it, but I'm up for trying anything at this point to not have to visit the dealer again. I am REALLY close to trading it in on a non-gm product. I have 800 miles on this truck and it's been in the shop two weeks for other issues unrelated to the window.

They do have to drop the headliner to fix it. The dealership had to replace my headliner because they couldn't get the stain out. When I picked it up last night, it looks like a rabid wombat took the trim pieces off and put it back together because there are gouge marks everywhere.

Seen this with another poster, looks like a bear clawed at his trim pieces. My guess is they require a special tool to remove properly and the oil change tech your dealer most likely used did not have the proper tools in his box, or simply didn't care which i have seen a lot of on here it seems. The other guy that it happened to on here i believe demanded new trim pieces and got them, i would do the same.

So I just got an email from my lawyer. GM sent them a form for me to fill out. They are requesting my loan information, account information, payoff amount, title, registration, etc. I hope this is good news but who knows. Dealer also called me this morning (I'm on day 56-ish???) Anyway dealer called and said back window is on order. So now "supposedly" there is a headliner and front windshield sitting in their parts department waiting for my back window to arrive.


I'm so done. My lawyer told me in the beginning this whole process is designed to wear me down and make me trade it in and take the loss - and they are right. I'm so done. Done waiting. Done reading forums, done not having my truck.

 

And then - even if I get it back, fixed, mint, like the day it came off the lot - How long  until it happens again? I'm in a good spot since it happened to me in the first two weeks @ 2200 miles. But what about next time? I drive 40,000 miles a year....F**king sucks. Screwed coming and going.

Happy for you Sam on the potential resolution.  Mine showed up 19 days after buying the truck and from the stain on the headliner it was leaking before I bought it.  I'm still waiting on GM to contact me.  According to NC law they've got until the 12th.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Some Assembly is Required

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
