Well I've lurked on this forum for a couple months. unfortunately I'm here because after leaving my truck at the dealership for 4 days they finally called back today and said GM has gotten thousands of calls about this issue and they currently have no fix for this, and they MAY in the future release a service bulletin. I'm highly skeptical though
on a different note I wish people on this forum would limit posting to relevant content because it has been difficult searching hundreds of pages for possible solutions.
just for the record my truck is a 2014 LTZ Z71 crew cab with 18" rims and the 3.42 rear end.
in all honesty I absolutely love the truck, but for such an expensive price this should not be an issue.
