About 3 months after I purchased the brand new, 2007, Honda Odyssey I noticed a reluctant feeling when I drove it. Even when I drove it around town for everyday errands or if needed to take long trips I still felt like my car was fighting me. Each time I brought my car in I would ask them to look the car over for a problem that would convey why I was having this bucking feeling. My first documented complaint was in April of 2008. They stated they could not find anything. My second complaint was October of 2008 stating the vehicle hesitates. Everytime I took it in to dch kay Honda in old bridge where we purchased the car they found nothing. It was not until my brother drove in my car in the winter of 2009, when he said there is something wrong with my transmission that I should take it to a transmission dealer and get it checked. I knew that if an independent transmission dealer looked at it or took it apart my warranty would be void so I found one who took it for a road test and stated that the transmission is slipping down to 4th and some how jumping into 5th automatically. After this I took it to dch kay Honda in eatontown and stated what was found out in Feb. Of 2009. They said again they could not find anything. I still have a reluctant feeling when I am driving the car but feel as though my time is being wasted by running back and forth to these dealers. I not only loose time, money but my car while either waiting for it or being without at home.
