| Description of the problem | I've got a 2005 toyota sienna xle with the power rear hatch. I think i've verified the problem with the hatch not retracting when it encounters an obstacle. Last year (first year of ownership) the hatch closed on me and would not retract. And, i was pushing back on this thing by arching my back. I'm not sure how i got out from under it but i did. It pretty much freaked me out. It was cold, and there was snow on the van. There was also an ice dam in the gap at the top of the door. I originally attributed my incident to this ice dam. (btw - chrysler's don't have this problem because they have a piece of plastic attached to the door that prevents ice from getting into this opening.) i continued to test my hatch on occasion from then on all throughout the summer and the fall. It worked just fine until dec 8, 2006. Dec 8, 2006, the temperature dropped to 33 degrees fahrenheit. It was a clear day. There was no snow. The hatch would not retract when i pulled back on it. It closed - even though i began applying upward pressure while it was still 90% open. If i had been between the closing hatch and bumper, i could have been badly hurt. If my children were there, it could have been worse. I am convinced that whatever is being used as a sensor in the door mechanism loses sensitivity during freezing temperatures. I'm suggesting that the reason the failure to retract can't be replicated at the service centers is because the car has warmed up enough by the time it gets there, or when it is worked on in a heated garage, the sensor then begins to work correctly because it is now "warm". Each time i've had the problem, my car was stone cold. It sat out overnight during freezing or near freezing temperatures while in my drive way. The engine had not been started. I was using my rear hatch to load/unload the van only. Now that the temperature has moved up into the 40's-50's, the hatch appears to retract correctly when it encounters an obstacle. *jb |
