Radio/tape Cd Player problems of the 2013 Honda Pilot

At various speeds there is a very annoying shuddering and vibrating and growling at 45 mph to 68 mph. Just when your ready to have a smooth ride on the highway it begins to shudder in eco. . . On a straightaway while free wheeling and while I am on cruise control . . . If you accelerate or decelerate, it will cease for a second and begin again. . I have even stayed at 68 mph to see how long it would last on a straight away while it was shuddering. . . . And it continued . . . Until I decelerated. . I also get these small bucks and surges , . Or a feeling of pulling me along but feeling like I am going to fall out of my seat at the same time. . In eco. Until the shuddering stops and then it feels smooth again, for a minute. . . . And then the shuddering begins again. . . . My tires are balanced and I have had an engine mount neutralizing. . . The Honda Pilot has vcm. . . It is very uncomfortable to your ears the vibrating. . . On top of your peace of mind on your way home from a day at work. . . . Looking forward to relaxing listening to the radio to ease yourself before you get home to your family life. . . Wow. . . Not relaxing at all !!! something is definitely wrong with my vehicle. . . .
