My husband noticed the 2004 Toyota Sienna moving in the driveway and found that the automatic transmission shifted out of park. He then played around with it and found that it can be shifted out of park without depressing the brake. I took it to the local Toyota dealership and was told that something broke off inside and would cost around $700 to fix it. They then said that my children must have broken it off swinging from the shifter. I responded that I really didn't think that my children did such a thing and the customer service rep admitted that they're probably not strong enough to break it anyhow. Thiswas very dangerous.
