2011 Toyota Sienna Seats
It is also possible to get the seat into this danger mode simply by lifting the seat adjustment lever and slightly moving the seat forward past the forward locked position. This scenario is possible when trying to accommodate extra leg room for a rear seat passenger -- thus leaving the middle seat free to travel ALL THE WAY forward without the passenger's knowledge.
We have reported this to our dealer, to Toyota of NA, and to the NHTSA. Toyota refuses to acknowledge the problem. I believe this is a major design flaw that you can so easily leave the seat in such a dangerous position.
There is another post here (mommy hate http://townhall-talk.edmunds.com/WebX/.f210245/6) where a user reports the seat sliding on it's own -- this could be the same problem. We thought it was sliding on it's own, too. Maybe it is, or maybe it's just sooooo easy for the seat to get into this unsafe mode.
Please post your experiences and please elevate the problem to Toyota.
