    L87 Failure - Taking formal action

    I briefly outlined my failure scenario in this post. Here is my plan to request that GMC deal with the situation BEFORE I have a safety issue at speed. My Argument: “GM’s known defective L87 engine is continuing to generate objective wear evidence after the recall remedy, and GM’s own recall...

    UOA and Filter photos of L87 time bomb.

    Let me tell you an L87 story, with documented evidence of how bad these engines are. My 2024 Yukon Denali is just over 2 years old with 20k miles on it. Passed the Pico Test at its first post-recall service. At that time the oil was changed to 0w-40 and got the new cap. 2500 miles later I...

    Changing Dash graphic of vehicle

    So kind of a silly question but I see that the truck represented on my dash is of the exact colors and options installed. If I were to change to black wheels and emblems, can the dealer change this? I assume they would laugh at me first ;p

    Where can I find a full coverage cover as shown here?

    Where can I find a full coverage cover as shown here for a 2024 Yukon? It goes up the sides and appears to cover the 3rd row when laid flat. I have big dogs and need this to protect the interior.

    6.2L Rough idle and poor low RPM response

    Just took delivery of a brand new 2024 Yukon Denali. Immediately upon pulling away from the stealership I noticed what appears to be a slight misfire at idle and a very slight hesitation upon throttle take up in drive. I'm pretty familiar with engine tuning as I race cars where I program the...

    Denali 22" wheels available.

    Anyone interested in a set of these Denali wheels? I bought black wheels instead. Tires reused so wheels are loose in boxes. In Pittsburgh, but will ship.

    Adaptive Air Ride ... driving me nuts

    Is the Adaptive Air Ride ONLY available with the Denali Reserve Package ??? (I know its also on the AT4) I want a Denali 'Tow Truck' with Air suspension and max towing package, but without the other $7000 worth of bling stuff. Am I out of luck?

    New Order Turn Around Times?

    What's the general lead time on the 2024 Denalis with 6.2L, air suspension, max towing package right now? Not looking for much more as far as options go. Are we looking at 6-8 weeks? Longer? Going to talk to dealers next week but wanted some thoughts from this group first. - Bill
