In our 2004 endeavor SUV the back seatbelts come undone without anyone pushing the red release buttons. I have 2 children car seats in the back and this has happened on at least 8 different occasions where the car seat is not buckled in anymore because the seat belt came loose. We took it in on 9-21-07 to dealer but they claim there is nothing wrong, but I have to question this because they only took about 10 minutes to look at it and then said it was fine and this keeps happening and is a real safety issue. I don't want to wait until something terrible happens I would like this to be repaired immediately.
