We have a 2004 Sienna and the power door has not been working for at least a year. I think the dealership told my DH well over $1500..... the whole door or something would have to be replaced. We also have had the doors freeze shut every winter (pretty much every day) since we've owned it. Really a pain!
I can remember at least two times, after defrosting the doors, that they would close...but not quite enough for the car to "sense" that they were closed and so we had to drive around with the "open door" alert beeper going off the entire time! One night, I drove my girls all the way to dance class and back with the alert beeping. We even turned the radio up full blast to try to drown out the beeping! LOL! Talk about making you crazy! When we finally got home I screamed "I'm so sick of this beepin car!!!!"....DS, who was 12 or 13 then, broke into hysterics! He got in the house and said "Hey Dad, mom is sick of the beepin' car!" We still laugh about that!
