2015 Tahoe LTZ - Noise From Hatch

So my wife just purchased a used 2015 Tahoe LTZ and when I got a chance to drive it I noticed a creaking/rubbing noise from the rear hatch, driver's side area near the tail-light. The noise occurs primarily at low-speeds and is present whenever the body is stressed (ie: pulling into/out of an inclined driveway) or passing over bumps on the roadway.

 

I checked the normal stuff in that area, floor cargo box (removed it), jack, plastic panels, etc. and everything seemed fine.

 

So I opened the rear-hatch and left it open while I tested it in a spot where I turn sharply to pull into my driveway which always makes the sound occur since it causes the body to tweak slightly and voila, no noise. From what I can tell it is coming from the rubber weather seal around the perimeter of the rear hatch rubbing against the metal body of the vehicle right next to the driver's side tail-light...

 

Anyone know a fix for this? Should I replace the entire weather strip or is there some type of rubber conditioner/lubricant I could apply to the existing weather strip? OR is my hatch closing too tightly and needs adjustment (it makes a loud rubber squeak sound from that area when the power latch engages tightly during its closure process)...

 

Thanks guys!

I tried a silicone grease that was highly recommended for this purpose and it didn't resolve the noise issue so I'm thinking it it something else on the hatch causing the noise; perhaps the latch or something inside the hatch door...

 

Anyone else have this similar noise issue with their hatch on a 2015+ Tahoe?

We had something similar on our Caddy...dealer finally found a wire loose under the plastic molding that would make a noise when the body flexed. Not sure if it was a break light wire or what, but they adjusted it and the noise went away.

I believe I finally got this resolved. I pin-pointed the sound from originating very low and center on the hatch so I inspected the striker for the latch and it had some shiny areas where it appeared that the OEM black coating had worn off. So I put some lubrication on it and the sound has completely stopped for the last three days. Therefore, I went ahead and ordered a replacement striker from my dealership so I can replace the worn one. :cool:

Glad you figured it out. Things like that drive me nuts.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
