Front Seat Power Adjust Problems of Toyota Sienna

3rd row power seats are malfunctioning and are operating while vehicle is in motion. Multiple times, and on different days, the power seats have started to close while passenger is seated and buckled in the seat. Occurred today while on the highway, at highway speed while my wife was seated in the drivers side 2 seat split. The seat started to close on its own - no one touched any button and we had been driving for over an hour. The seat put pressure on her until it stopped in a partially closed position. The seat buttons then did not work to reopen the seat back for several minutes. This would be extremely dangerous for a small child. This has happened in a similar scenario on multiple occasions and we are certain that the power seats are malfunctioning.

The third row power seat became inoperable. The seat back would not come up so someone could sit there. Toyota has a technical service bulletin (TSB) and it is t-sb-0183-09. Toyota knows that they have a problem with this seat. This is a safety issue because the seating capacity is cut and no seat belts for the passengers. I was out of town and we had to fold the seat down to pick up some larger items and when we dropped those items off, the seat would not return to the upright position. It was the larger portion of the 60/40 seat; therefore cutting my capacity by 2 people. Luck for us, we are a family of 5 and were still able to make it the 300 miles home with everyone in a seat with a seatbelt. If we had one more in our family I don't know what we would have done. I am able to do that type of repair but it was still over $500 dollars to repair. If you take it to the dealer it is around $1000! there is no manual override or any way to get the seat to work. You must replace the seat track assembly. Now my other side has quit working! this is a safety concern! they say the van has a capacity of 7. With that seat not working it is only 6. This would be different if Toyota didn't already acknowledge that there is a problem. I was a automotive technician for 15 years and I would accept this as a part failure, if it was isolated. It is a problem enough for Toyota to recognize it and give it a TSB! this should be a safety recall.
