    Dangling Yellow Wire After Dealer Service

    I found instructions for my 2023 Yukon that say the yellow wire needs to be connected to Body Control Module X7 pin 24 "Rear Footwell Accent Lighting Control". I did that and put a magazine over the light sensor on the dash, but the rear door sills didn't turn on when the rear doors were open...

    Metallic Rattle While Accelerating - Dealer Can't Reproduce (video)

    I'm familiar with engine knock and if it were that the dealer would have been able to diagnose it quickly. The noise is easiest to hear in my video at 0:02 seconds. It sounds like a "shudder" but only occurs when accelerating around 2k RPMs. It is most apparent with headphones and the volume...

    Metallic Rattle While Accelerating - Dealer Can't Reproduce (video)

    While accelerating around 2-2.5k RPMs, a noticeable metallic chain-like rattle comes from the engine area in my 2023 GMC Yukon Denali Ultimate (34k miles). My vehicle is under warranty, and I've demonstrated the problem for the shop foreman, but he "can't hear it." Another tech said he did hear...

    Dangling Yellow Wire After Dealer Service

    I picked up my 2023 GMC Yukon Denali Ultimate from the dealer (Thompson GMC - Raleigh, NC) after they performed the Trailer Brake Control Switch recall, and noticed a dangling yellow wire in the driver footwell. For safety, I've taped the end with electrical tape until I figure out what it's...
