well people I have been doing a lot of checking about the VCM Honda Odyssey Van and It seems that they have been having many Problems with vibrations and a Shudder at certain speeds and at certain RPM. The following website has 37 pages of comments on among others a rear engine motor mount which appears to be poorly designed and collapses.
The website is http://townhall-talk.edmunds.com/direct/view/.f1085e1/0 . I was completely surprised at the amount of purchasers of this Van who would never buy another Honda product. Many were just plain disgusted with Honda and the way they were told that this vibration was normal, when it fact it was not. Some people spent literally thousands of dollars trying to isolate and correct this problem.
a Different site http://accuratecars.com/blog/2008/11/26/excessive-engine-vibration-with-eco-on-the-honda-odyssey-ex-l-and-honda-odyssey-touring/ a clearly shows the rear motor mount, one bad one good and explains how to check for a bad one. I don’t know what to do now. I still would like a Odyssey, but I do not want half the problems some of these purchasers have encountered. Anyone else who want to add anything please do, but at this point I am blown away that a full scale recall has not been called for on these vans and the resulting problems with the VCM engines.
