Not yet, but it is currently in service for this problem (I just turned it in yesterday). I'll post an update here, once they tell me what's wrong.
I had this occur as well. Changed regen to low and seems to have resolved it.
Mine has it. I notice it when under 10mph, whether accelerating or decelerating under regen. It is much more pronounced and obvious when towing a heavy trailer. I'm trying to figure out how to explain it to service, so they "get it".
Last fall, they told me it was tire cupping, but it's not. I was recently towing this camper, and stopped on an incline. When pulling away, under that heavier load, it was vibrating much faster than the tires could have produced (because they were barely rolling). That told me it was definitely the drivetrain, and not tires.
I have also put the truck in conserve mode, just to test whether there was a change, but it vibrated just the same. That tells me it's coming from the front end.
One idea for describing it: The rapid vibration you would get when rolling a hexagon-shaped pencil across a desk with your hand on top of it.
Does anyone have a better description?
Has anyone had service identify and fix this? I have an appointment in 4 days, and having the cause would save us all a lot of time.
P.S. It started 1-2 months before buying this travel trailer.
I think I have the same issue and I took my truck in for service about it. They kept it for about a week while the technicians would try to recreate and determine what may be causing it. Eventually they came to the conclusion that it's related to regen and Hold/ABS when traveling at very low speed. You can get it to go away almost completely if you turn off hold mode (rock crawl lets you do this, I can't remember if other modes let you) and turn down regen.
