Approximately 250 miles after the 15,000-mile maintenance, at approximately 70 miles per hour on I-95, the Odyssey began jerking, lunging and clunking. We immediately pulled off the road and telephoned american Honda motor company customer care. We were told to proceed to the nearest Honda dealership in fayetteville, nc. A mechanic took a five-minute test ride. The van did not replicate the jerking and clunking and we were told there was nothing they could do and we should proceed on our way. We were also told that if there were any problems a indicator light would have illuminated. The service department did not look under the hood or check any systems. Ten minutes later on I-95, at 60 miles per hour, the jerking and clunking resumed. We called ahmc customer service again. At specific request (the representative had no clue which dealers were close to us) we were given phone numbers for other dealerships further along our route, but, when we called three different dealers, their service departments were closed. We stopped at a gas station and checked under the hood. There was no transmission fluid on the dipstick. We called East coast Honda and spoke with guy emerson. We asked guy what was done to the transmission. ''we didn''t touch the transmission'' was guy''s response. We called ahmc customer service again and were told there was nothing they could do to help us though we were 70 miles from home. The gas station did not have the automatic transmission fluid recommended in the owner''s manual and ahmc concluded that we could use ''type a'' transmission fluid as a temporary replacement. We put in some of the transmission fluid the station stocked, and got back on the road. Soon the van continued to jerk, lunge and clunk until we got off I-95 and proceeded on back roads in third gear (D3). We made our way slowly home and, the next morning, we called the dealership that had serviced our Odyssey less than 48 hours and 400 miles earlier.

The van begins shaking, then stalls when cruising at any speed between 50-60mph. This also occurs at approximately 40mph. When starting from a stop, the car is increasingly failing to start in 1st gear. This is a major problem when trying to turn lft across traffic. Also, when braking to slow the car (not stop it) it will suddenly shift to a low gear, throwing the driver into the steering wheel (when this occurs, the seatbelts do not automatically tighten or otherwise restrain the driver or passengers). It is like a 20mph head-on-collision. According to the Honda customer service rep, this is a design feature. The dealership informed us the transmission is operating normally and all the problems are "features" not problems. Nice to know Honda has engineered a "give the driver whiplash" feature into the car, as well as a feature to cause the car to stall at the state highway speedlimit. I suppose it is to help Honda's bottom-line by having Odyssey owners bring their vehicles in for regular repairs after being rear-ended by other cars on the freeway. Please note, all problems started after the dealership installed the dvd player we purchased at the time of sale. It was supposed to be the Honda dvd system, but we are pretty sure it is not.

The van's engine warning light and traction control light came on at about 2700 miles while I was driving the vehicle. In addition, the vehicle gear shift was in the "D" mode for drive, and the green light began blinking off and on at the same time the engine light and tcs light were illuminated. The Honda dealership replaced the pressure control solenoid and this ended the lights being display. Today, at 3100 miles, the engine warning light and tcs light came on again and the "D" gear shift light was blinking off and on. I took the vehicle to the Honda dealership this morning and was told 5 hrs later that my vehicle needs a new transmission. I am shocked and also disappointed. It is new and cost $30,000 to purchase. What a bum deal.
