| Product type code | VEHICLE |
| Description of the problem | I bought a new 2006 toyota sienna van. From the beginning, the transmission drops into neutral as the vehicle slows for stops. Upon acceleration to move through a stop sign or light, the transmission hesitates in neutral, leaving those following about to rear end the vehicle. Or, if you accelerate, the vehicle lurches into gear throwing passengers forward. I have mentioned this problem every time i have had the vehicle serviced. The serviceman acknowledges the problem, and states that toyota claims it is a means to save the transmission. The jerking on the transmission as the vehicle goes into gear after a stop cannot be good for the vehicle. The serviceman further stated that other car models made by toyota had experienced the same problem, but that a "computer patch" had been made available that solved the problem. He said that no such patch has been made available for the sienna vans. My concern is that i will end up rear-ended because of the hesitation or that the transmission will fail. |
