2004 TOYOTA SIENNA User Comment / Complaint

In december, 2006, my tailgate closed on its own, injuring my wife. toyota replaced the rear stays (struts) under warranty, including the addition of some brackets. at first everything was fine. but when the weather turned colder (below 20f), the rear hatch would not open on its own unless opening under power. and then a couple of days ago (still very cold), the hatch closed on its own under power again. this time, my daughter and i were both in its path, but fortunately, so was a shopping cart. there were fortunately no injuries this time. i am frustrated that just 45 days after the problem was "repaired" it is already happening again.
