    2021 6.2L Yukon Denali Dead Battery Gremlin? Not the truck?

    The truck has been perfect since the lifters were replaced. They aren't speculating that the lifters influenced/were influenced by the battery, but man, that's an odd coincidence. Perhaps some of the failed starting caused the lifter's vulnerability to surface. One other thought on the...

    2021 6.2L Yukon Denali Dead Battery Gremlin? Not the truck?

    In a super wild turn of events, we have lifter failure at 60k miles. Possibly from all of the hard and incomplete starting? An otherwise perfect truck with no issues, one that has seen nothing but AmsOil Signature oil every 5k. I was just under the 60k mark for warranty and the dealership had...

    2021 6.2L Yukon Denali Dead Battery Gremlin? Not the truck?

    I have had this truck since day one, 60k miles problem-free. I buy a new truck every year/every other year for business tax purposes and recently gave this older one to my mother (also an employee of mine). Since she got it, truck has died in her garage 3x times. Completely dead battery...

    How are you cleaning your Yukon's stock exhaust tips?

    P21S polishing soap occasionally. For my weekly washes, I use the same product that I use on my wheels, which is P&S Brake Buster (similar name, different brand). I will say, stay on top of them if this sort of thing bothers you. An ounce of prevention is worth a pound of cure...

    Goofy Codes? Check your battery.

    Our 21' 6.2l Yukon Denali, which has been otherwise pretty good, threw itself into limp mode yesterday. A call to OnStar showed p1400 ECM - Engine System, p16f3 ECM - Engine System, and c2a07 ABS - Braking and Stability System. I thought it was strange that both the engine and braking/electronic...

    Fabric wheel liners?

    An electric pressure washer cleans them out in one or two passes. I do it during my weekly wash. 40 degree tip. 1500 or so PSI. Look at options from a brand called Active. Greatly prefer felt to the plastic of yesterday.

    2023 Denali ultimate dash rattle/sound

    Yes, to confirm, I'm referencing removal of the entire "t-shaped" piece that contains the defrost vents, speaker grill, and light sensor. I started on the passenger side, right of the center channel speaker grill (on the trim piece itself, not the speaker grill itself, the grill is attached to...

    2023 Denali ultimate dash rattle/sound

    I've had this problem on the dash center trim piece, surrounding the center channel speaker, on my 2021 and 2023 Denali, worse on the 2021. I accepted that I'm extremely fussy and for me, it's never turned out great when I've tried to warranty out these things that I can fix myself, with far...

    2023 Change in Door Pockets from 2021?

    Recently traded in my 2021 Yukon Denali for a nearly identical 2023. The upper door pockets are missing rubber liners this time around. Can someone share with me the part number from their’s? I remember them lifting out. Does anyone with a 2023 have them? I wonder if it was a change or they...

    After 7.5 months told order not accepted???

    Yesterday I found a 2023 Denali on the GMC.com inventory section, in transit. I figure it's a long shot, most of these are spoken for, but might as well call. I had my credit card out for a deposit while waiting for the receptionist to transfer me to a sales rep. Lupient GMC in Minnesota. To...

    Service Safety Restraint system - need permanent fix please!!

    I've had the same message come on a handful of times. It's some sort of system logic-based error in most cases. The fix is the best part: cycle your overhead map lights on/off, both of them, and it will go away. The Germans have dealt with these issues for years. More complex systems = more...

    Tahoe/Yukon accessory hardwire

    I used the BlendMount/MirrorTap on my 2021; + is the mauve/purple and - is the black with the white stripe. To clarify, I'm using the plug at the very bottom of the area covered by the mirror/windshield housing. I'm also using the vehicle end of the plug, rather than the end that goes to the...

    Corsa Releases New Exhaust For 6.2

    I thought it was pretty raspy for what I was expecting. Sounds cool, but not for a daily driver, at least for me. So now I have a 1k exhaust repackaged as nice as i could, in a huge box, taking up space in my garage. Corsa won't take a return on an installed item, and I don't feel like...

    Corsa Releases New Exhaust For 6.2

    Nothing deliberate, I was too frustrated and didn't think of it before taking it off. One of my security cams picked it up though.

    Corsa Releases New Exhaust For 6.2

    So….the 6.2… I hated it. Couldn’t it pull it off fast enough. Extremely loud at startup on the 6.2, and I mean extremely. Far louder than what I expected from Corsa’s own promotional video. The exhaust is so loud at startup in the garage that keeping it on a daily driver would be unfair to my...

    Hands Free Liftgate logo is blurred/distorted

    Mine did something similar, cleaning did nothing. Ended up ordering a new unit for $49 shipped from GMPartsStore under part# 13540010. Could I have warrantied it? Sure, but just as easy to order it myself and swap out on my own in 5 minutes.

    Key fob cover for 2021 Yukon?

    I ordered one from Story Leather. It should be here in a few weeks (built to order) and I'll try to remember to post some photos.
