My H3 is doing the same thing in the steering. I told the dealer that I believe it was the steering shaft because I had the same problem on my 1998 Jeep Wrangler. They did absolutely nothing to my car
My loaner with 1500 miles was doing the same exact thing - steering column vibrating and hopping and pedals vibrating when turning. It seems that the gremlins only come out when i'm driving, the dealership said nothing was happening when they drove my car. I guess I will try a different dealership.
