    2021 Tahoe Braking performance?

    Sorry Polo, that info is totally bass acwards...at least 70% of your braking effort is concentrated on the front. The front Brembo brake package (or any other 6 piston fixed caliper system) with 16" rotors and 6 pot calipers are not cheap but would totally transform the braking capability on a...

    Reconsidering my order

    I love my old Tahoe, but have had it with GM and their long history of using their first model year customers (or two or three years) as their final validation program for new platforms. When you're spending $75-$100k+ for a vehicle, you want it right. I've had many good GM vehicles over the...

    I'm Out

    I almost bit on purchasing a GV80...twice. First in December of '20 then a year later at another dealership. While it had ALL the bells and whistles one could want, it was too small and neither of the salesmen could work the all-encompassing infotainment system. At $74k, that was a concern...

    2022 Yukon Paint Quality

    I certainly feel your pain, having an $80k vehicle with crappy fit/finish. But I gotta tell ya, the fix may be worse than the problem. Some knucklehead is very likely going to hit the panel with a sander down through the zinc, to bare metal. (Those body panels are stamped from galvanized...

    Duramax with Catalytic converter issue

    Just looked up "renewable diesel". Found this from the gov't.... https://www.eia.gov/energyexplained/biofuels/biodiesel-in-depth.php Looks similar to a gasoline a flex-fuel type situation. Sounds like there's different types of "renewable diesel" fuels. Depends on the percentage of biomass...

    Which Tahoe to buy?

    Congrats and good luck! I think you made a wise choice with the '19.

    Which Tahoe to buy?

    Personally, I would avoid any MY earlier than 2019. Given GM's commitment to using their early adopters as their final validation methodology in virtually every new model launch, they finally got the 2Kxx bugs worked out in '19 and especially in '20.

    2nd time Lifter Failure... 2021 Yukon AT4

    I would take exception with the "Anything in the 20-21 years is in for issues". (except for all GM 5.3 and 6.2 motors ;)) GM is notorious for developing new platforms on the backs of their early adopter customers, which the past couple of full sized SUV's, has lasted for at least the first TWO...

    needing some input - do i pull the trigger?

    Anxious, being that you asked...Personally, I would not force feed getting a vehicle that you're not totally satisfied with. (And definitely, NOT with a dealer that plays word games.) In any case, you are attempting to make a serious purchase at precisely the wrong time. With the chip...

    2021 Yukon Denali---POS

    Kind of a broken record, but I've lived through a couple of GM's first model years...you can be assured that you are PAYING THEM to be a guinea pig and the final "validation" segment, before they get it right.

    (Non) Patiently Waiting

    It's not just the Amazon effect, it's the iPhone effect, the instantaneous internet news cycle, Twitter, etc. etc. that promotes all of the impatience. Many (most?) people expect to touch an icon on their phone/computer/iPad, whatever device, and get immediate action on virtually anything...

    Bad Timken Hub Asembly?

    GM uses these one piece sealed hubs on many cars/trucks. (BTW, NO difference between the GMC and Chevy truck bearings.) In contrast to the old tried/true roller bearings, these one piece units are ball bearing hubs made for quick OE assembly. I used to replace them regularly on my C4 Corvette...

    I joined the 21 master class

    I agree with Quark...here's a post of mine from last October: I don't know understand the "bad" reviews. I've had 22", 20" and 18" Alenza HL's on Escalades, Tahoe's and Lexus GX460's. I found them to be great in snow and heavy rain. I took off a set of Michelin Defenders with about 30,000 miles...

    4 Piston Big Brake Upgrade from 2019-20

    Ah, I think we're all in agreement that Silverado's are not race cars. Obviously, the fellow who did exactly what you stated couldn't even get his truck to screech to a halt because his system was a total mismatch of components. My comments were to those who might blindly choose to follow the...

    4 Piston Big Brake Upgrade from 2019-20

    Regarding the original conversion video, there are a couple of thoughts and issues that need to be addressed, as there's no sense going this route unless you dramatically improve your stopping power. 1) Adequate volume/force brake master cylinder 2) Correct F/R brake bias (after market valve)...

    Concerns with new generation Yukon

    Wow, Thislife1977...Why the vitriol? Quark stated his approach to making an informed $80K or more decision. I'm 110% in the camp that takes a very critical approach to a test drive. I have posted a number of times regarding my desire to replace my 2010 Tahoe LTZ with one of the then "new"...

    Best tires for a 2017 LT w/18" wheels?

    Big fan of the BS Alenza HL on a 3 ton vehicle. Had them on a 'Sclade, Yukon and my Tahoe. Had them on one of my Lexus GX 460's and they were a tiny bit stiffer than the factory BS model tire. And while it sounds like you're not going to be in any white stuff other than sand, it won't matter...

    ‘21 Tahoe - Cold on Drivers Side, Hot Passenger Side

    Tell her to keep taking it back to the dealer for anything that's not right to build a lemon law case. This is another classic case of first model year GM fails.

    Yukon Denali 2021 Haunted Nightmare - Request advice

    Keep taking it back to the dealer for everything to build a lemon law case. I hate being the GM first model year guinea pig. (Did that with an '07 Escalade and a buddy went through it with the '84 Corvette and another, with an early Fiero.) They ought to discount every redesigned vehicle 25%...

    Did GM stop taking orders for 2021 Yukons?

    Sad to say, but this is classic first model year GM blues.

    Considering 21 Tahoe LT or Z71

    I wouldn't disagree if I were coming into a Chevy/Cadillac/GMC dealer cold and was playing "let's make a deal" with the salesman, his sales manager and then the GM. I had already been down that road with enough dealers to know what the best deal was. When you can get top dollar for your trade...

    Considering 21 Tahoe LT or Z71

    You handled that exactly right. Many, many people only care about their monthly payment and I believe that's why so many sales people ask questions that have nothing to do with the actual money difference. To those in the know, it is very frustrating. Including my new GX, I actually had two...
