Hello Everyone,
I have a 2021 Yukon XL with 29k miles on it. Just recently I noticed while driving around my neighborhood, I would hear what sounds like metal hitting metal. I slapped my go pro with an external mic under the truck and the rattling was more clear. The rattling seemed to start while on 2nd or 3rd gear with the engine under load….sounding like it was not idling high enough. You can see the transfer case and exhaust shaking at the same time when the rattling starts. I would post the video here but seems there’s no option for it. I have taken my truck to the dealership and they could not replicate the problem. So they asked me to take it home. I showed them the video and my adviser himself agreed there’s something rattling. Any input would help. Thank you!
