I have 2010 Odessey for about a month. When driving on the highway
it feels very darty .I'm always making slight corrections. Also when I stick my gps on windshield the gps vibrates alot. Any clues to what is going on. Is it designed this way or is something wrong. I thought either one or more frontend parts are loose or maybe more positive castor is needed. Or maybe bad frontend design.

 

welcome to the forum. I was told many years ago, that honda does not do an alighnment to their cars from the factory. Suggest you advise the service dept of the vibration and wanders. Be sure to document all information in writing, for a few days and allow Honda to fix the problem. They will always come back with a "This is normal" or "The van needs to be broken in" Continue to document time, date, miles per hr, miles driven, etc. This is in the event you have to take it to another dealer or call American Honda, you have all the info written and no have to guess.
