    2024 Z71 mpg .. can it be this bad?

    I'm sure those 22's weigh more than the 20's which won't help city mileage.

    2024 Z71 mpg .. can it be this bad?

    Uhhhh yeah, that is part of you issue. The rims and tires. Don't be surprised if your hwy mileage sucks as well.

    2024 Z71 mpg .. can it be this bad?

    You don't even have 500 miles on it? Don't do anything until you've run at least 1000 miles and check it then. Wouldn't be surprised if the tires/rims on the AT4 decrease your mpg's a bit.

    Idea On Cost To Replace 5.3 Engine? 2015 Yukon XL

    FWIW, my friend just had the engine in her 14 Suburban replaced. $8500 at a local shop. Dealer wanted $11K.

    2017 Tahoe with very rough idle

    Does the vibration go away if you increase rpm's at idle by 100-150? A lot of these trucks have a rough idle from GM setting the idle speed so low. Probably not your issue if it just started.....

    Are the 2021+ Tahoes that much better than a 2020?

    Your 2020 is barely broken in. If you can take the hit financially AND really think a new one is that much better, go for it. I would have kept my 2010 had rust issues not reared their ugly head. Of course there is the keeping up with the Jones's thing......

    Fuel efficiency drop in newer models ?

    Agreed. No way will you get better mileage than a diesel. No way. If that is real, GM would buy that truck for a million bucks to see what magic is going on there.

    Fuel efficiency drop in newer models ?

    High octane here is totally useless if you don't need it as 93 is currently $1.20/gal more than 87.

    AFM/DOD Questions

    Re your original problem, this is a common thing. I think GM wants them to do some elaborate test for engine mounts. Mine has a slight vibration at idle, but it only idles at 500 rpm. That is awfully low. Bring it up to 600/650 rpm and the vibration goes away. I think a tune can adjust that.....

    2012 Tahoe needs a new engine

    Anyone replaced their unused spare tire due to age?

    Only one problem with a 5 tire rotation. If you have alloy wheels you will have a mismatched set of rims with the steelie spare.

    Vehicle purchase help (Tahoe/Suburban)

    My 5 are all inside. I always find it amazing that people will park $150K of vehicles outside to protect $1K worth of junk in their garage. LOL!

    2018 tahoe lt

    Not a Z71. Wrong badging, running boards, and front fascia. Z71's had 18" rims, not 20's. I think skid plates were a stand-alone option. Does it have the 2 speed (hi/low) transfer case?

    Considering a 24 or 25 Tahoe/Yukon or Suburban

    Toyota went back to a solid rear axle on the latest gen, which really affected cargo/seat space. Every review I've seen questioned the logic of this.....

    LowCountryTim's 2011 Tahoe Build Thread

    A lot of people use aftermarket dash pads on these. Depends on how factory you want it to look and how bad the current dash is.

    Maybe not all 6.2's have the bad lifter bore/ bearing wear issues

    That's not how I read it. It says only vehicles with an Open Vehicle History Screen are affected. It also says certain vehicles are affected, not all. Also read Engines used for replacement must be specially ordered by dealerships and allocated to specific VIN numbers. No way every 6.2L is...

    Should I be hesitant to buy a 2023 Yukon Denali Ultimate?

    Figured as much. No way I was going backwards from my 2010 when I sold it.

    Should I be hesitant to buy a 2023 Yukon Denali Ultimate?
