I haven't heard any noise from the rear of my 2017 CR-V Touring, but I have another similar issue. When visiting family this past weekend, I had 2 adults sitting in my backseat for the first time. While driving I noticed that the rear end of the vehicle seemed to "slip" a few inches anytime I was above 35 mph. It would slip both directions, and my brother also noticed it as he was sitting in the right rear of the back seat. I stopped the vehicle and checked the lug nuts on all four wheels. They were tight, so I resumed driving and again experienced that swaying "slip" feel. When I dropped everyone off, my wife and I drove home (a 120 mile drive). I did not feel the slip at all on the drive home as the back seat was empty. I am concerned about the possibility of a sway bar or stabilizer bar being loose and possibly leading to losing control of the vehicle. After arriving home, I got a couple of friends to ride in the rear seat while I drove down the highway, and I again felt the "slip" and both of my friends noticed it as well. I am taking it to the Honda Service shop tomorrow. I bought the vehicle in March, and this is the first problem that I have had with the vehicle. Any ideas????
