So it seems now that the real source of the leak are these spoiler bolts that are not properly sealed with the sealant? So water passes through them and soakes the headliners?
 

That is correct.  And the TSB does not really address the spoiler bolts all that well.

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.

Well that seems to be a much simpler solution than the original TSB. Would of saved alot of owners some headaches and trouble if thats the case?

 

Did GM redesign the bolts or do they instruct the dealers to apply sealant every time before the bolts are reinstalled?

If they do it obviously is not right since my truck has been back 4 times for it leaking lol

I’d say that the spoiler is ONE source of the leaks. The other is clearly the sliding window frame cracking.

Had my 19' Sierra repaired a while back. Was leaking on both sides, passenger side was worse. Dealership I use did a great job. Have to look really hard to see the sealer that was put on the back glass. The tech that works there does all of my warranty work on all my vehicles. He always does excellent work. Have never had to return any for the same issue twice. Has not leaked since repair was done. I did ask about the spoiler and if he thought that it could also be leaking from there. He said that he has not had one yet to be leaking from the spoiler, all he has seen were the back glass leaking. He has done so many he can't count.

Just got my 2019 sierra back from getting the TSB for the spoiler bolts done and low and behold it still leaks. I guess they didn't even check it before telling me it was fixed. It will be going back Monday morning. Looks like this is going to be a long aggravating road. I knew I should have just bought another Honda!!!!!!!!!!!!!!!!!!!!!!

Does anyone have this supposed TSB for the spoiler bolts? I have the one for the window, but didn’t know one existed for bolts on our trucks.

Never heard of the spoiler leak issue. As I stated in my earlier post, the tech I use said he has not had one in with the spoiler leaking, it has always been the rear glass leaking, caused by cracks in the plastic frame that is sandwiched between the body and the glass. Not saying they don't leak, but the tech that did mine said none of the spoilers were the issue, and he has done a lot of these trucks.

So my rear window is cracked but i sealed it up and the spoiler bolts, it does not leak anymore. my dealer said he would replace the window he has seen where the plastic frame is cracked in 3 places. Is it just going to crack again if i get it replaced? Or should i just go ahead and do it. Id hate to see my interior get torn up just for the window frame to crack again. Thanks in advanced fellas and hope yall get yours fixed.

Nobody can answer until GM comes clean on why they are cracking.

So you're saying its pretty much pointless, it'll just crack again?

I am saying that only GM knows and won't say.

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
