Engine Belts And Pulleys problems of the 2013 Honda Pilot

I changed tire ,bushing stabilizer,wheel balance alignment, changed the tie rod and cv axle but the car still shaking between the speed of 60mph-70mph. . I don't remember when my Honda Pilot 2013 misfired then they fixed it but my timing belt everything was making sound , I spent to my mechanic friend coz the dealer charge me a price of 950$ to do timing belt service.

I purchased my 2013 Honda certified pre-owned in August 2015. Test drive was short and felt no issues. Felt the shudder on a highway drive the next day. Now I question if the salesperson knew this would be noticed and deliberately made the test ride short to avoid this being noticed. I even asked her about the vibration issue from reports I had read about before the purchase. I was told this was not an valid issue and that she had owned a Pilot and never felt anything. The car was brought back and a software update was done as well as fluid change in trans within the first month. It still had the shudder. After driving for a few weeks to give it a chance to prove itself and it not me "looking" for a problem I called and spoke with the service manager to report this and inform him I would coming back when my schedule allowed. It is getting more frequent and it does not seem to matter whether in eco mode or not. The shudder usually happens around 38-42 mph. But will begin anytime the vehicle cruises in any speed range continually. At higher speeds I can feel my skin shake like one of those fat burning shaking belts from years past. (just so you know I am of average build without excessive body skin. ) brought the car back a second time. That was today Feb. 3, 2016. Went for ride with the service manager. Told him it seems to be getting worse. His conclusion was that this "shudder" was a "characteristic" of my $28,000 purchase. My 1999 suburban that I traded in had a better ride. Very disappointed with Honda. I am going to another dealer to get a second opinion.
