    2021 Suburban LM2 reliability sob story

    My wife's '21 had a leaking exhaust issue, their is a tsb for that. If you search for posts under my account one of them has a link to the tsb on that topic. "I think" it was specifically around a weld on the flange for the turbo.

    Engine coolant level in surge tank ?

    These systems don't consume coolant. Totally possible that it wasn't 'full' from the factory. But once the system has stabilized you shouldn't see any coolant reduction day over day. If the level is dropping it's because it's leaking.

    dmax 3.0 and the cold (-30F)

    The cold happens regardless of the hvac setting. IE, you can feel the cold hitting the back of the console. This isn't cold from the ac, it's outside air. A soda in the front cup holder will freeze when your driving down the interstate at -30F for example.

    dmax 3.0 and the cold (-30F)

    GM isn't recommending a grill cover or anything else beyond blocking or unblocking the vent within the console. It gets cold with or without a phone on the charger. No resolution yet; nor do I anticipate one to ever occur.

    Buying Used

    Based on my experience of owning multiple baby diesels (both eco & duramax), multiple large diesels (5.9, 6.7, ISM, ISX) and say 20 gas variants (bmw/ram/gm/jeep) These 3.0 diesels are the most problematic engines available today, 100% hands down. I've also had many air suspensions fail during...

    A few questions on my 2024 Denali

    Maybe on the first one or two; but after 'some number' the above doesn't happen anymore. I have so many more important things to worry about; vehicles are like number 10 in my list of concerns.

    In what situations have you used 4L/4Low?

    Backing up an incline with a 5k+ trailer; thats when I use 4L in the Denali. At one of our places the shed has a decent incline, 4L makes backing up way easier when loaded. Otherwise just regular auto or hi.

    Buying Used

    The 21+ mechanical issues are similar to the AFM issues of a few years back. Basically a "pick your poison" type of deal. If you wanted to minimize your exposure to high repair costs I'd recommend the following: - fewer options, fewer problems (get a Tahoe instead of an Escalade) - skip the...

    A few questions on my 2024 Denali

    Based on your phone choice, the wireless android auto / car play works rather well once setup. Beyond that I haven't really found anything super useful in the wife's denali.

    5.3 Guys, opinion on oil change intervals

    Follow the 'oil life' indicator; the difference between 5k and the 7kish that the dash is going to say isn't going to matter. If you are worried about the oil being 'used up' have it tested (or go read about all the folks that have their oil tested). The pattern is that modern oil doesn't...

    Tracked 2007 Tahoe for sale

    Started with PistonBully 200's; had 7 of them, very difficult to keep operational. Transitioned to the Jeep xj's; the positive being they could fit on the narrow trailers. Cooling was miserable on the xj's and they are just to small in the back seats. Now doing Tahoe's; cooling is...

    I suppose it's possible that both the harness AND the injector have failed, at different times but on the same cylinder.

    Getting rid of dead mouse smell?

    As someone who has gone through a bunch of old mice'd up jeeps; you haven't found all the dead ones yet :) I'd suggest you drop a couple traps in your garage as a precaution. Sometimes when you buy a truck you get some free pets :)

    2022 Tahoe RST: Impressions

    I used to work with the CEO of GM when OnStar first came out. The above was part of the vision they had for it in the early days (and... imagine if it worked across any GM you'd get into, think rental car). Why o why haven't we gotten their yet?
