Good morning.   I've seen all the posts about the leaking sharkfin, however I doubt that is the cause of this; this is occurring at the opposite corner of the headliner.

 

I noticed last week a good size stain on the headliner at the back/passenger corner. 

 

2019 Tahoe w/ 15k miles, no mods, no crashes.  I haven't been able to find anything in the search here or the google machine.  Has anyone seen this??

I have not seen it either, but I still wouldn't discount the shark fin because you know it has been known to leak.  If the shark fin is leaking, you were traveling at speed limit, in decent rainy conditions, it could be the shark fin.  The only other items attached to the roof is the two top siderails.  I believe the lip above the liftglass is welded.

Ok!  I am slightly suspecting the two wire harnesses that pass through from the roofline to the hatch because they're in that corner of the cargo area.  However I can't see any obvious reasons for it leaking there.

Update:

After overnight rain, I was able to track down the leak.

I found water and water marks on the area of the lower D pillar, and when pulling at the liftgate trim some water dropped out. 

I removed the trim and found water above the lower metal of the roof.

Upon further inspection I found water dripping out of the connector that connects the body to the liftgate.  I'm presuming the gasket that seals the connector has failed.

I'm currently at Chevy having it looked at to determine a course of action.   Will be interesting to see what they'll do about the stained headliner.

I remember using foam upholstery cleaner with a brush to clean some grime left by a mechanic.  Auto store brands are similar, try your favorite brand.

I just noticed this on my 2020 Tahoe today... headliner stained in the same exact spot.. I’ve always noticed small amount of water in cargo area after car washes but always thought maybe it got in after opening hatch... only have 9k miles on it so I’m definitely taking it in to see what they will do about it...

Any update to how the issue was resolved? I just bought a used 2018 Tahoe and have the same issue. Noticed it after taking it through the car wash the first time...

It's usually the plastic "backbone" inside the harness that breaks, causing it not to seal. 

If you're lucky, it just came loose and you can click it back into place.  If not, it needs a new one usually.

Are there any updates on how you resolved the issue?  I've taken mine back to the dealer 3 times, they changed the wiring harness and weather stripping and it still leaks in the same place as yours.

 

Thanks

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      By davester · Posted

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
