What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

[the 18th letter]

Back of my seat has popped off twice yesterday. I’ll look at it proper once it’s light out.

Is that a 2015? It seems to be a pretty common problem, my 14 sierra had the same problem. I put newer model seats in it that don't have that hard back piece.

If it’s an issue with your model year there should be a YouTube on how to repair or a Goggle search.

You have to replace the seat back. It either stretches out the plastic tabs that hold it on or breaks the bend on the end of the tab off.

Yup, 2015 Yukon. Something def seems broken tab/clip wise. When I get it back in place the bottom carpeted part is never flush. The passenger side, pic attached, is flush at the bottom.

Yep that's why I got newer version of the seats.

Changed the oil. My wife can DRIVE! It seems like I just changed (because I probably did). 155k and still moving along.

This girl will never be a low mile garage queen......we are way past that. Now it's the 'how many miles can we put on it' game.

Swapped out the stock Denali grill for a black one today. This was a pretty cheap one from AMZ ($170 or so delivered), but everything lined up nicely. Couple hours and 2 beers. I actually like it with the stock red emblem. Slowly de-chroming, but it was too humid to paint today. Mods keep me busy...

I saw a couple cool ideas on YT for a zip tie fix.

How much disassembly is required. I’m going to do this before summer is over. I got wrap for the window frames and fog lights but may go with painting instead. If I paint a grill I’ll probobly paint, but with a grill like yours I think wrapping might be more uniform.

it wasn't hard. Had to pull the whole front bumper cover. 6 screws and 6 pins on top, 7 screws around each wheel well, and 8 screws and 2 pins on bottom plus a couple tabs. I had all the fasteners out in about 20 minutes (just have a 10mm, 7mm, and t15 ready to go), then pushed out clips for another 20 minutes. The damn connector for the fog/front sensors gave me more hell than anything. Swapping the actual grill and emblem was another 15 min or so just popping tabs. I plan to use hyper dip piano black for the fogs surrounds and door/rear moldings...

Exhaust continues to evolve. First was tsp long tubes, catted y pipe and oem muffler. Sounded too high pitched and raspy.

Now I'm at headers, catted y pipe, and a single flowmaster pro series. Cold starts are too spicy for how early I leave so I'm probably going to put the flapper valve back in.

Next step will be cutting the y pipe in favor of the "borla switchfire".

Picture was taken when mocking up, everything is clamped or welded

Sounds great. How much were the long tubes and how hard was the install? You 4WD?
How's it sound at WOT?
I really want to add headers to mine at some point.

If it's anything like my 05 there will be a lot of hammering.

These are what I got, except I found them on marketplace lightly used. Definitely a chore to install. Took me a whole weekend, but it was also was my first time doing headers and I'm a notoriously slow and steady worker. I do have 4wd, and didn't have any clearance issues. I changed my spark plugs at the same time, couple places mentioned that removing them gives more space to slide in and piece of mind that you won't break one. You'll need a variety of shallow and deep sockets, extensions, swivels, wrenches, etc. There are numerous helpful install videos on YouTube, especially for Silverados, but the process is the same. WOT sounds like a flock of bald eagles.

Appreciate the information. Header install on my 5th get Camaro was a breeze. But the clearance on the Tahoe seems much tighter so I'd imagine it's a pain in the ass coming from the top or the bottom. (I assume bottom)
Apparently the headers for the 2019 cost $1000 more. No clue why that's the case on their site, don't understand what changed from 2018 to 2019 for bolt-on exhaust routing..

Down the line it'll be worth it for the WOT bald eagles you described. Feel free to post more videos of such, if you feel like it.

 

[k_arnold72]

Passenger side had to slide in from the bottom because of my hoses and lines in the engine bay. Driver side from the top, because I didn't want to remove the front drive shaft.

**Edit** @Jeff_ forgot to mention that you'll need O² extensions as well, downstream driver side and upstream passenger side. Be mindful of all cables and fuel line etc, make sure they're well supported or insulated.

So far in the 2 1/2 weeks I've owned my 2015 Yukon XL Denali, I've replaced the corroded shark-fin antenna, installed LED bulbs in all front head & fog lamps and backup lamps, treated exterior with ceramic protectant, replaced cabin air filter, installed mats in 3rd seat floor and cargo area.

Does the screen stay on if it is in the raised position? or is it normal.to turn off when it is lifted up? Also if I put my hand on the top and apply any pressure at all the screen goes off. Trying to diagnose a issue

 

[CMoore711]

@Doubeleive The screen in my ‘15 Yukon XL Denali always turned off when the screen was raised. Just like in your pic.

Not sure about the applying pressure from the top and it turning off?

 

[RST Dana]

Everyone one of the three I’ve owned went off when raised.
