    Does anyone know the exact failure mechanism of the lifters?

    I've got almost 24k on my 2021 with no problems, but I typically run 150k+ miles between trucks. Has there been any actual info on what is failing and if we as owners can do anything to help prevent it? These new trucks are calling for 0-20 oil which is super light, especially in hot weather...

    Substance Dripping

    Wipe it with a white cloth so we can see the color. Does it dry up or stay a droplet on a cold pipe? That will help determine if it's oil or water based.

    Best source for a GMPP warranty currently.

    Thanks. I actually bought my C6 warranty from Dennis. Great group of folks and the price could not be beat. I'll make sure I reach out to him when ready to pull the trigger. I'm at about 17k miles, so I have a little more time.

    Best source for a GMPP warranty currently.

    GMPP warranties have a lot of price variations depending on the dealer. Usually there is a dealer somewhere in the US that sells them far under most dealerships. I haven't bought one in a while and was curious if there's some consensus of who that "discounted" super GMPP dealer is currently.

    Automatic High Beams

    Mine quit working as well. Very strange. It's on my list of warranty issues next trip. If you get it fixed, please let us know.

    Quick Questions for Current Owners

    If it helps, I've tried almost everything to keep wheels clean. Armor All actually has a product that works. It's an aerosol called Wheel Protectant. Put it on clean and they will stay clean for quite a while, even with brake dust.

    21+ Exhaust

    Just for clarity, you completely removed the muffler? Did you leave either of the flapper valves in position and what about the resonators? Is this on a 5.3 or 6.2? Can you quantify "incredible"? I'm looking for more sound and horsepower but I've been down the drone at cruising speeds and...

    Well found out that the 2021 will only idle for 30 minutes and then shuts off

    Someone's gong to find out the hard way unfortunately. I would have never figured that and would have left my pups in the A/C from a key start event while going into a restaurant during a road trip.

    Lane keep assist

    I can't imagine how that would affect the systems that monitor the lane assist. It's a camera in your front dash that is designed to work with various topography. My gut feel is your mind is playing tricks on you. Mine goes over the lines a little as well normally. Don't rely on it to keep...

    Interesting SXM discovery

    It took a few trips to confirm this, but I have noticed if you have enough time with the radio on, your satellite radio will actually buffer your presets and holds the upcoming song on pause right near the beginning. That way when you cycle through the presets, you always start at the...

    Remote start engine runtime on ‘21s

    Why is this a problem? If you are concerned, just hit the key again and it will stop whenever you like. The more troubling issue is if you leave your truck running with the normal start function, it will not idle longer than 30 minutes. If you left your dog inside with the A/C running on a...

    21+ Exhaust

    What model Corsa did you install? Did you keep any of the valves and/or resonators?

    rear ended on the tow hitch, what should i check for damage?

    Honestly, as a mechanical engineer, I would certainly replace the pin. I assume it hit on the nose of the hitch forging and not the ball. If the ball appears to be hit, they are cheap enough to replace as well. It's just good insurance. There are crack detection solvents if you really want...

    305/45/22 will fit nicely!

    I forgot I never reported back... Zero rub issues with stock ride height. Easy upgrade and really make a visual upgrade over those stock tires. Extra width helps protect those wheels from the wife driving

    Oil Catch Can

    Check out my post on Oct 25th on the "what did you do to your truck today" thread. It has pics of my Elite Engineering Catch can install. (I've deleted my phone pics). I highly recommend putting one on. You will get a pool of oil quickly in yoir intake and it's imperative to keep this down on...

    Adaptive cruise

    You can switch modes by holding the cancel button a few seconds. A notice how to do it pops up on the screen a couple of seconds when you engage ACC.

    Rear end cover

    If the level is above the axle height, you're probably OK with an inch shorter, just less margin of safety so keep it topped off. You can always squeeze hard and overfill while quickly putting the plug on if it helps you sleep at night. Be sure those external magnets stay put (expoxy?) ...

    Volant CAI for 21 Denali

    Does it actually pull in cold air or is it basically a less restrictive filter / snorkel? Thinking about this one and really close on the 6.2 performance exhaust (if it only didn't cost so much!)

    Key FOB Question

    Removing the battery is the sure fire way of doing this. You can also try wrapping it in a few layers of foil and placing it about mid-cabin (away from the steering column / doors / rear proximity sensors). This may attenuate the signal enough that it would not think it's still in the cabin...

    Disabling the auto shut down feature

    I work out of my truck and need power / climate control often on a job site. There is no way to get past 30 minutes of idle time, even sitting in the truck the whole time. I work out of my passenger seat, so I have to get out and go to the driver's side and do it all over again. I got to be...

    XM radio won’t load on 2021 Tahoe

    Lost mine the other day as well. Didn't know this is a potential problem, so thanks for posting this. If it does it again I'll try and get it on video, because I guarantee it will work when I bring it to a dealer.

    Check Your Engine Oil Level!!!!!

    FYI, that small overfill is probably not anything to worry about. In fact, if you were to run in a brand new engine until the computer change interval, you would probably want that little extra until everything seats in well and it slips a bit of oil. One thing to note for everyone, is the...
