We purchased this van in 2002. We owned it for 8 years and 120K miles. Overall, I was disappointed in the quality of the vehicle. It did have some good interior and exterior features. The engine was always reliable. However, the transmission was a train wreck. We had to replace the transmission 2 times while we owned it. We had numerous issues with the power sliding door. Every so often I had to clean the connectors with steel wool or the door would not shut properly. We recently traded off the van for a Toyota. The little things like nobs, handles, buttons, etc. were starting to fail. The gas mileage was also starting to diminish. I would be hesitant to purchase another Honda Odyssey van.
Engine was always reliable. Easy to maintain. Some of the interior features such as the climate control and placement of the nobs and buttons was well designed. It drove well in the snow and on family vacations.
Bad transmission design - replaced the transmission 2 times. Power sliding doors - we experienced numerous problems. A majority of the problems were with the door not shutting properly and the alarm going off. Interior nobs, buttons, handles, etc broke easily.
