    Does a 2024 Z51 with 6.2 require premium fuel?

    Not a dollar a gallon extra here for Premium...is about $0.50/gal if you shop smart...Sinclair and dinopay app gets you $0.10/gallon discount, use Costco CC and get 4% cash. back...or get the fuel at Costco and their price is about what Sinclair's is w/ DinoPay app...but in my neck of the woods...

    Open & close driver window, passenger window, and service instrument cluster

    Going to have to wait for the dealer. This sounds electrical…could be indicative of a bad ground. In order to figure it out, need to know the schematics and what might be in common between BCM and Instrument panel.

    Well, that’s gotta be a relief. Suggestion: Download a copy of the owners manual on GMC.com and read it…you will likely learn a lot. Quiz: 1) how do you turn the dome lights on and off? 2) how do you change the dome lights to not turn on when opening a door? 3) how do you open the power lift...

    Vanity mirror bulb replacement

    If I had to guess, since they are LED, they are not bulbs, and not replaceable...but I have not tried to disassemble mine to confirm.

    New 2023 Tahoe--Need reco on Add on CD Player

    Well, the Stellantis guys figured it out w/ a polarized coating on the front passenger display, they get a full LED screen in front of them and it just looks like shiny glass from the driver seat..so...there are ways to figure it out...just that GM didn't. In Fairness, my kids are grown, and I...

    Interior lights come on by walking close

    Ok, so the vehicle has this feature (Turn on interior lights when it is dark and you approach the vehicle) It is by design, likely for safety lets you see inside before you open the doors, to make sure no nefarious occupants are inside. Part of this process is the fuel pump kicks on to prime...

    HVAC mildew smell

    I have noted that the smell had subsided somewhat from when I last posted. Still humid as ever here this summer, so I don't think a lowering in humidity had anything to do with the change. Vehicle in at dealer yesterday, they: - Enabled afterblow - Changed my cabin air filter (said I need to...

    2021 6.2 Tahoe eats oil like crazy - is this truck getting lifter issues soon?

    Do not wait until low oil light comes on. Ask for a proper oil consumption test. You will void your warranty if you let your engine run low of oil, as well as destroy it. Like it or not, GM considers any consumption less than 1qt/1000 miles normal. Work with your dealer, not against them.

    Using Bluetooth audio in 2024 Yukon Denali?

    Yes, no sweat. Works fine from my iPhone when NOT using car-play. Want to test -- disable CarPlay in your iPhone settings, and just connect your phone as a phone and audio device... Shares recent call log, shares contacts if you want, can play music, no big deal. Did this often when struggling...

    HVAC mildew smell

    Called dealer today, they are going to take it Monday, diagnose and fix...at least that was their promise. Even offered me a Loaner to drive! Will report back when I am done w/ the service. Did read this online today re: Afterblow function on the trucks...

    Open and close windows

    Probably a sign of low battery. That is the auto up/down feature calibration after battery is disconnected, from the owner's manual.

    HVAC mildew smell

    Add me to the list, my 2022 is starting to stink now...anyone else brought this to the dealer's attention...what was the reaction? My Cabin AC Filter was changed 5k miles ago...so would think it isn't that...but planning on pulling it tonight to inspect.

    Extra fuel tank

    the good part about running mining her at those speeds is it probably keeps the Dynamic Fuel Management from turning off any cylinders!!

    Extra fuel tank

    Because, the majority of these vehicles are sold in USA, and speed limits are set between 60 and 80 MPH, and I think only South Dakota has 80. So GM shoots for the “target market” range of around 350 miles..they have to trade off the required CAFE fuel economy requirements (weight) with the...

    Extra fuel tank

    Ok, fair point, but guessing the OP isn’t driving at a constant 110-115 MPH. And no US car maker sizes the fuel tank for continuous operation at those speeds.

    21 Yukon Screech from rear passenger side when turning, braking at low speed

    This was the TSB I was referring to, but it seems to imply front wheel noises. https://static.nhtsa.gov/odi/tsbs/2022/MC-10225732-0001.pdf Probably not it, but I’d still take it in

    Extra fuel tank

    I regularly can go 475-500 miles in my Denali XL on the highway. At 19MPG, the 28 gallons will take you 532 miles if you go to the limit. I can easily get 19 on the highway. My City MPG is around 15.5-16; that yields a range of 434. If I drive all city, I usually go 325-375 miles and squeeze...
