    [SOLVED] Hauling dirty/big things in Tahoe…

    Last fall after a good hunting trip, we put three large does in the back of my 2023 Premier for the trip to the meat processor. With the jump seats folded down and using a large tarp, we had zero problems.

    Towing hitches specifically

    If you're only towing a small landscape trailer, I'd go with a fixed ball mount with an 8" drop. Draw Tite, Curt and many other brands are available.

    Going to chance it

    I've decided to forego the Range DFM Module GM Refresh. Physically, I'm not able to remove it myself for trips to dealer's service department. I'll turn off auto stop each trip and will change oil between 3,000-3,500 miles. How dumb am I being?

    Michelin Defender LTX Tires

    I just had a set of Defender LTX M/S installed two months ago. They're very quiet, track well, and steering response is great. Last weekend we got 5-7" of ice, sleet, and snow followed by a deep freeze. Our streets are very hilly and the VDOT snow plow couldn't get to us for 4 days. I put...

    Do I wait for the 2027 MY to come out? Buy new now?

    I understand from reading this forum, eliminating AFM/DFM doesn't eliminate engine failures it just postpones them a while?

    Disabling AFM

    I've been disabling AFM using L9. I've noticed in city driving, the transmission feels sluggish and the shifts are not precise. When I go back to D it's like the Tahoe wakes up and performance is much better. For highway driving, I like the performance using L9, Is it critical to use L9 in...

    Passive Locks Issue

    I have the same problem with my passenger door passive lock. I googled this: "where is passenger passive lock fuse located on 2023 tahoe" and Google AI said the fuse is number 26 in the passenger side fuse box. I checked it and it's fine. Next stop dealer.

    Does Knapp Extended warranty negotiate pricing at all?

    None of the local dealers would sell me a GMPP. I used Knapp. Local dealers must accept GMPP in the event of a covered claim.

    Correct tire pressure question

    With the wide swings in temperature this spring, I'm seeing the same swings in my tire pressure. I set mine at 35 psi cold on a 75 degree day. On cool mornings, it reads 33-34 cold and 35-36 afterdriving. On warm afternoons or when towing boat, it reads 36-37 cold and 39-41 warm. I realize...

    Best place to buy extended warranty

    Here's my two cents worth: 1. From experience, buy the manufacturers plan. 2. Generally, it'll be cheaper to buy sooner rather than later. 3. Go ahead and contact now one of the recommended dealerships on this thread and they can answer your questions with facts. I'll add Todd Southerland...

    2023 Premier Cylinder Deactivation Questions

    First, should I be getting a notification on dashboard when engine deactivates cylinders? I don't get anything now. Second, I've read if I run in 9th gear it will deactivate the DFM? If true, how do I do this?

    Is this normal?

    I haven't been to the dealer but will schedule a visit soon. I'm fairly certain it's not stuck in 4 wheel drive. On one steep launch ramp I use, I have to put it in 4 wheel to pull out without slip.
